Your account will be renamed
Hello,

The developer team at Wikimedia is making some changes to how accounts work, as part of our on-going efforts to provide new and better tools for our users like cross-wiki notifications. These changes will mean you have the same account name everywhere. This will let us give you new features that will help you edit and discuss better, and allow more flexible user permissions for tools. One of the side-effects of this is that user accounts will now have to be unique across all 900 Wikimedia wikis. See the announcement for more information.

Unfortunately, your account clashes with another account also called Wilasinee. To make sure that both of you can use all Wikimedia projects in future, we have reserved the name Wilasinee~enwikiversity that only you will have. If you like it, you don't have to do anything. If you do not like it, you can pick out a different name.

Your account will still work as before, and you will be credited for all your edits made so far, but you will have to use the new account name when you log in.

Sorry for the inconvenience.

Yours, Keegan Peterzell Community Liaison, Wikimedia Foundation 23:47, 17 March 2015 (UTC)

= Problem 1 - Find $$\begin{align}y_{xxxxx}\end{align}$$ =

Statement
Find $$\begin{align}y_{xxxxx}\end{align}$$ in terms of derivative of y with respect to t, where $$\begin{align}y(x(t))\end{align}$$ and $$\begin{align} x=\textbf{e}^{t}\end{align}$$.

Solution
Applying the chain rule to $$\begin{align}y(x(t))\end{align}$$

Then solving for $$\begin{align}y_x\end{align}$$

Taking the derivative with respect to $$\begin{align}x\end{align}$$

Then solving for $$\begin{align}y_{xx}\end{align}$$

Taking another derivative with respect to $$\begin{align}x\end{align}$$

And again solving for higher order derivative with respect to $$\begin{align}x\end{align}$$

Repeating the process again for the fourth derivative

And again solving for higher order derivative with respect to $$\begin{align}x\end{align}$$

Repeating the process one final time for the fifth derivative

And solving for fifth order derivative with respect to $$\begin{align}x\end{align}$$

Note that the coefficients of the equation for the derivative with respect to $$\begin{align}x\end{align}$$ of each order form a Diophantine equation which sums to zero. This is expected as if $$\begin{align}y\end{align}$$ is constant with respect to $$\begin{align}t\end{align}$$ it should also be constant with respect to $$\begin{align}x\end{align}$$

General Solution Method
There is a 'general' recursive algorithm for finding the coefficients of the partial derivatives with respect to $$\begin{align}t\end{align}$$. Expressing the nth partial with respect to $$\begin{align}x\end{align}$$ as a sum of partials with respect to $$\begin{align}t\end{align}$$.

The first coefficient is always one

The second term initiates the recursion and is

Then the next coefficient is found by multiplying each term by the terms to the right, dropping the terms where there are no terms to the right. To demonstrate $$\begin{align}y_{xxxxxx}\end{align}$$ ($$\begin{align}y_{n=6}\end{align}$$) will be found without using $$\begin{align}y_{xxxxx}\end{align}$$.

Then each term times the polynomial to its right

Again applying the recursive rule

Applying again for the fourth term

And once again for the last term

Thus $$y_{xxxxxx}$$ is

The solution is checked by noting the sum of coefficients is zero, i.e. $$\begin{align}\scriptstyle 1-15+85-225+274-120=0\end{align}$$.

User:EttoreGreco/Wavevolution (Deutsch)

In englisch Wavevolution und auch Wavevolution (English)

Wavevolution "den Zusammenhang zwischen Wellen und Materie und die daraus resultierenden Konsequenzen für das Universum und die Menschheit.

Definition
Wavevolution ist die Korrelation zwischen Wellen und Materie und die daraus resultierenden Konsequenzen für das Universum und die ganze Menschheit. Wavevolution erweitert das Konzept der Evolution, um alle Formen der Energie durch einen Prozess der allmählichen Veränderungen verwandeln Wellen in Atome. Diese Transformation zeigt, wie die Energie-Bewegung in Atomen und in Wellen identisch enthüllt die Schaffung von einer einzigen Bewegung, die für alle Energie ist. Eine solche Änderung ist aufgefallen (und teilweise missverstanden) in den wave function collapse oder auch in der photoelektrischen Effekt nach Energie  Absorption in Masse durch elektromagnetische Strahlung  s (das zeigt, wie die Photonen und deren durchgeführt Potenzial umzuwandeln  subatomaren Teilchen). Dies bedeutet, dass alles, was existiert, einschließlich der Menschheit, Energie aus transformierten Wellen entstanden ist. Von Einsteins Hypothesen wird berichtet, dass Energie und Materie analog sind, sondern dass die Energie-Transfers (nach Einstein) durch zwei getrennte Mechanismen: Partikel und Wellen. Diese falsche Division zeigt zwei Formen von Energie, Teilchen und Wellen, als ob sie nicht austauschbar waren. In jüngster Zeit ist das Konzept eines Teilchens unter neuer Kontrolle im Lichte der Experimente, die den kleinsten Teilchen, nur wie Wellen verhalten gezeigt haben. Welle-Teilchen-Dualität ist das Konzept, dass alle Materie und Energie weist sowohl wellenartige und Partikel-ähnliches Verhalten. Eine der Auswirkungen dieser Welle-Teilchen-Dualismus ist, dass Photon s, berechnet auf die Frequenz haben, Wellenlänge, Amplitude und andere Eigenschaften innewohnen Wellenmechanik werden. In diesem Zusammenhang Wavevolution unterscheidet sich grundlegend von der Welle-Teilchen-Dualismus in dem Sinne, dass während dieser letzten Theorie hält das Photon als ein Teilchen verhält, wie Welle statt für Wavevolution Wellen in Partikel zu verwandeln. Was Wavevolution sind Wellen und Teilchen austauschbar und es gibt nur einen Mechanismus, um alle Energie-Transfer. Das ist die Quantenmechanik. Die Quantenmechanik ist hier als die natürliche Anziehungskraft zwischen zwei entgegengesetzten und komplementären elektrischen Ladungen bestimmt. Wavevolution auch identifiziert sich mit allen Erscheinungsformen von dieser einzigartigen und konstante Energie Verhalten als Indikator einer einzigen Universal-Gesetz (Quantenmechanik), die orchestriert alle Energie im Universum, wie in einer Sinfonie für eine große gebrochene Symmetrie. In Wavevolution,-Symmetrie ist überall. Alle Elemente haben eine elektrische Ladung, ein Gegenstück. Messe weniger nicht vorhanden ist. Neutrale Elemente sind Verbundwerkstoffe aus zwei entgegengesetzten Ladungen und keine Elementarteilchen. In Wavevolution Alle verwandeln.

Abweichungen von den Standard-Modell der Theorie
Einsteins Theorie definiert das Universum in einem geschlossenen Raum, dass es nicht erweitern schrumpft, dass http://it.wikipedia.org ist ein [ / wiki / Universo_statico statischen Universum]. Dies ist "das Gegenteil von dem, was wir ein paar Jahre später mit der Rotverschiebung des Lichts mit dem Hubble-Teleskop und dass stattdessen gibt es eine [http gelernt: / / it.wikipedia.org / wiki / Universo_in_accelerazione Beschleunigung Universum] und in ständiger Expansion. In einem statischen Universum, und alle diejenigen, die angenommen haben, seine Theorie Einsteins geführt worden, zu glauben, dass die Atome sind immer Atome, da " Anfang der Zeit. Bis jetzt, mit diesem Erbe ', nach Einstein, Wissenschaftler eingeführt berühmten Theorien genannt das Standard-Modell, String, und" M "Aber das Universum" alle ergebnislos zu demonstrieren, wie die Big Bang erstellen bleiben. In ihren Theorien, versuchen Wissenschaftler Bang erklären die Schöpfung mit atomaren Teilchen bereits bestehenden zu der Zeit des Großen]. In der Theorie [[w: de: Modello_standard | Standard Model] gibt es mindestens drei Arten von Bosonen W, Z und Photonen neben Gluonen. Partikel wie Bosonen gegen Masse W + und W-haben ein neutrales Element in ihrem dritten fünf Boson Z. Dann Elementarteilchen]. Die Z-Bosonen sind Teilchen, die Träger vermitteln die [[w: de: Forza_nucleare_debole | schwache Kernkraft], um Bosonen W + und W-als auch das Photon (masselosen als durch das Standard-Modell) statt den elektromagnetische Ladung. Die schwache Kernkraft und die elektromagnetische Feld sind beide das Ergebnis von der gegenüberliegenden Bosonen W + und W-, zwei Einheiten Masse. Im Standardmodell der Theorie und des Photons "gilt als eine fundamentale Teilchen mit Masse nicht hinaus und ohne eine korrekte Verfall von Energie trotz des Standardmodells Theorie bestätigen, dass die Energie des Photons kann" durch Wechselwirkung mit anderen Teilchen übertragen werden. Das Photon und "hier" im Widerspruch Beispiel. Wavevolution In der Photon "elektromagnetische statt verstanden als Teil der beiden gegensätzlichen elementare Teilchen tragen, dass Gebühren. Denken Sie an zwei gegenüberliegenden Ladungen (Elementarteilchen) im Inneren einer Welle wie zwei konvergierenden Pfeile Reisen im Raum, und ein Funke aus ihrer Reibung "erzeugt um die beiden Pfeile, so dass" bis zu ihrer imamgine spiegelt genau die Funken. In Wavevolution dass Funke genannt Photon ist nicht "ein Elementarteilchen, sondern ein Produkt der beiden entgegengesetzten Ladungen (wie das Spiegelbild der Energie). In Wavevolution die Masse der Photonen, sondern weil es "so s Licht bleibt zu entziffern.

Waves zu Atomen
Wavevolution Theorie und" den Prozess der Veränderung eintritt, und ihr Potenzial zu Photonen w geliefert durch eine konstante exponentiellen Abfall, die verwandelt. sogar die gleichen subatomaren Teilchen wie Photonen links nach Funktion verstehen Kollaps der Wellenfunktion Decadimento_esponenziale Die Auswirkungen dieser Umwandlung sind auch relevant für die Erschaffung des Universums. In Wavevolution in der Quantenwelt Universum ursprünglich von einer Welle transportiert wird allmählich fragmentiert durch einen Verlust von Energie durch Störungen aufgetreten. Zum Beispiel, ein großer Teil der  gamma in der Zeit durch die Verringerung ihrer Energie Potential,  Raggy X und Röntgenstrahlung allmählich  UV usw. abnehmenden 'auch ihre Frequenzen. Die ursprüngliche Quanten von Energie und "Fragmentierung verwandelt in verschiedene Formen von Energie durch spontane symmetrisch. Da die Wellen und Reisen mit anderen zu interagieren, wie viel Energie, ändern sie ihre potentielle Energie. Mit Planck-Gleichung E = hv, wobei E 'Energie, er ist der Planck-Konstante Vorabend' Frequenz, werden einige Wellen weniger häufig nach der Wechselwirkung. Nach Erreichen einer kritischen Quanten von Energie (weit unter dem Radio), um die Wellen Zusammenbruch bilden zwei subatomare Teilchen mit entgegengesetzter Ladung. Durch kontinuierliche Masse Aggregation und allmähliche Veränderung mehr und mehr "komplexen Formen der Energie, die wir von den Wellen auf den Menschen es. 'S nie wissenschaftlich Atome dokumentiert die Transformation von Wellen zu, obwohl wir w wissen aus Radioaktivität ', dass die Atome in Wellen umgewandelt werden. So "auch wenn wir nicht beweisen können, die Transformation von Wellen zu Atomen, haben wir Beweise für das Gegenteil Transformation. Es ist wie, zum Beispiel, wenn ein Eisberg fällt an den Küsten von Afrika und Menschen zu sehen, das Eis im Wasser schmelzen, aber da hat nie Wasser gesehen Gefrierpunkt zu Eis erstarrt wegen ihrer heißen Klima, hatte er Zweifel über die doppelte Transformation. Obwohl die Technologie ist nicht "noch in der Lage, um die Transformation von Wellen in Atome nachweisen, aber wir haben" eine große Anzahl von Forderungen als Beweismittel. Konventionelle Weisheit hat bewiesen, dass etwa 3 Millimeter Kelvin Photonen in Elektronen und Positronen sind für einen Moment verwandelt und dann sofort nach Selbstzerstörung. Konventionelle Weisheit und "nahezu bestätigt Wavevolution. In der Tat, eines Tages werden wir bald feststellen, dass bei einer Temperatur noch cool, diese beiden entgegengesetzten Ladungen nicht zerstören "einander, sondern beginnen, Masse bilden eine neue (versuchen diese Umwandlung genau das Gegenteil der Strahlung.

Über Zeit, Raum und Bewegung
Für progressives Wavevolution Wissenschaft enthüllt die Existenz eines Gottes und nicht als "bis jetzt möglich gewesen, für die Religion und Wissenschaft. Wavevolution Atome zeigt zum ersten Mal als die Bewegung von Energie in sich identisch mit dem in den Wellen. Wir) 'definieren können diese Bewegung als eine Richtung (oder sogar ein Wille, da "es und" konstant und immer gleich. Wir wissen jetzt eine Bestellung vorliegt. dass in Bezug auf jede Form von Energie und' kann vorhersagen, welche wird "seinen nächsten Schritt auf der Grundlage der Qualität" seiner Elemente. Complexity "trafen, um Bewegung vorherzusagen und" proportional zur Komplexität "dieser besonderen Form der Energie. Alle Formen der Energie, die zusammen das Universum, sind orchestriert von der gleichen und immer Übergangslösung zwischen ihre Magnetfelder vergleichbar sind viele Stücke, die bewegen sich in einem Schachbrett selbst und ewig. Seit 'Richtung (' oder 'The) und Staat nicht angegebenen Reihenfolge durch diese erzeugt durch die menschliche Rasse (es gab sogar vor der Menschheit ') Seine Anwesenheit bedeutet auch, die Existenz eines Schöpfers. Obwohl es möglich ist, Kenntnis von der "ausgedrückt in diesem Gemälde, und dass" das Universum kann nie wissen, der Maler aber nur darauf achten, dass er existiert. Irrtümlicherweise Konventionelle Weisheit erklärt, wie all die Energie, die Universum existiert in der Nummer konvergierte bei einem (mit eigenem Raum) zum Zeitpunkt des Urknalls über 14700000000 Jahre alt ". Darüber hinaus zeigt die herkömmliche Weisheit, dass diese Single Point of Energie im ganzen Universum geschaffen wurde. Diese Theorie "ohne Fundament, zeigt ihre Unzulänglichkeiten von vornherein Alle Räume sind teilbar und mindestens zwei Punkte werden immer gebraucht für die Koordinaten eines beliebigen Raum. In der Tat konnten wir immer zweigeteilt in für jeden Bereich mit einer Bewegung, die Zeit kommt zu einem. Es gibt keine Zeit und Raum ohne Bewegung. Es gibt keinen Raum und Zeit ohne Bewegung. Nicht Time and Motion existieren ohne Space. Aber wenn einer der drei gibt es die beiden anderen. Wenn die Schöpfung Bang Big eingeleitet durch einen Punkt mit einem eigenen Raum die, die schon vor, Punkt könnte die nicht gleich sein der ' Anfang der Zeit, und der Schöpfer aller Dinge. Eine bereits vorhandene Platz zum Urknall, impliziert zwangsläufig die Anwesenheit von einem bereits bestehenden in der gleichen Explosion. Darüber hinaus eine ungeteilte Raum unmöglich existieren. In der Tat, die mehr Platz 'konnte nur einen kleinen Ball und auch wenn der Punkt von Energie (vor dem Urknall) war unendlich klein diese konnte nicht in der Form einer Kugel. Die Kugel hat einen Durchmesser Perimeter Perimeter, sondern auch kleinere, wenn Sie weg bewegen aus dem größeren Durchmesser (oben oder sogar darunter Durchmesser). Der Begriff der unendlich kleinen schließt die Möglichkeit "eines Perimeter mehr" klein. Das Unvorstellbare Punkt unendlich klein (nicht entweder eine Kugel sein), wenn explodierte gleichzeitig würde Herkunft verteilt seine Energie aus einem einzigen Punkt aus. Der Platzmangel nell'indivisibile unendlich kleinen Punkt würde auch die Anwesenheit von Zeit und Bewegung für die Erschaffung des Universums. Während des Universums 'Zeit geschaffen. Also das Universum nicht starten "durch ein Leerzeichen. Creation auch, weil es sich vorstellen, ist schwer zu" den Ursprung, die Ursachen "der Explosion von Energie, war noch nie bewegt durch eine andere Ursache (Gott sei" die erste Ursache). Der Begriff der Ursache-Wirkung-Ursache, gültig in unserer Welt, nicht "gut für Gott und seine Schöpfung. In der Tat, in unserer Welt, Leben und" eine durchgehende Kette von Reaktionen. alles, was existiert, ist "eine kontinuierliche Reaktion (Ursache / Wirkung / Ursache), die stammt aus einer "ewig" vorherigen Fall, dass alle leben und "die Wirkung von einem früheren Fall, sondern auch die Ursache für eine neue Wirkung. In der Tat sind wir nicht bekannt, dass Kraft, die fähig zu bewegen und hat sich nicht zuvor Kraft bewegt um weitere drei. Aber wie kann "Die Existenz einer von der ersten Konzepte entwickeln nichts? Jede Existenz (wir wissen, dass der) lebt immer eingeschränkt innerhalb: Zeit, Raum und Bewegung. Zum Beispiel, in jedem Moment der Zeit, die Sie besetzen einen Raum in Ihrem Leben, und dass "die Bewegung. Diese drei Konzepte werden immer zusammen, und sonst" der Mangel an Existenz in unserer Dimension. Infinity konnte nie Physik oder vollständig erklärt werden gesichtet wie Mathematik, Chemie. Es wird "Sprung von der Plattform dieser kleinen Größe. Zeit, Raum und Bewegung entstand gleichzeitig als Gott, eine Dimension der Stabilität," Ursache "a Move ( genannt Big Bang), die symmetrisch teilt die Energie und die Rekombination Zeit, wodurch der "Raum in einer kontinuierlichen Expansion des Universums. Ereignis des Urknalls, das Universum geschaffen Spiegel wie ein gebrochenes, zerbrochenen Spiegeln in vielen mehr "Kinder, die ständig wieder vereint und getrennt durch eine einzige Bewegung. Wie ein großes Puzzle, alle Seiten eines jeden Spiegel sind symmetrisch gegenüberliegenden und ergänzenden Seiten des Spiegels, und dass" an ihrer Seite. Zwei benachbarte Spiegel Bewegung hingezogen zu einem Natural (Quantenmechanik) und zusammen schaffen sie eine neue, dritte Form von Energie. Auf diese Weise, das Universum Gott weiterhin von der Idee zu erweitern ....... auch Fragmente von Ihrer Energie mit der Veranstaltung Big Bang, zu Universum breitete sie in einem expandierenden (mit Dimensionen Zeit, Raum und Bewegung), will sich die Füllung "unendlichen Leere (Größe, ohne Zeit, Raum und Bewegung.) Quantenmechanik ist" Gottes Instrument, das immer wieder neu vereint und wieder trennen die Energie, um Energie zu erzeugen neue Formen der. Eine Kreation mit einem Anfang und für die Ewigkeit. "Always", Konzept so unerreichbar für uns ist dies die zeitlose Brücke und füllt einen kleinen Maßstab (Universum) und unendlich (die Leere). Was gibt es jenseits des Universums und im Laufe der Zeit? Wenn es stimmt, dass wir zählen rückwärts 14600000000 bis 14700000000 Jahre, und auch, weil nicht 14,8 Milliarden? Vor 14700000000 Jahre her, da war die Zeit. Was dann? Nur Gott, der absoluten Stabilität ".

Erstellen
Der Zeit des Urknalls gab es keine Masse, sondern nur die Wellen, die Energie tragen in der unendlichen Vakuum. Das Universum ist nur ein kleiner Teil der Leere, die auf Energie erreicht ist. Wenn wir das Universum von außen beobachten konnte, sieht es wie ein Nebel in der Form eines Kreises nach innen gebrochen und durchzogen von einem Wind je. Der Energie-und 'wie der Wind, der Universum durchquert den Nebel in ewiger Geschwindigkeit, die je einzugreifen und die Erweiterung des Umfangs der. Wie kann "das Universum weiter ausbauen Warum?' die Wellen Universum reisen am Rande des nicht noch nie getroffen (und nie begegnen) jegliche Einmischung in die Leere. Diese Wellen immer weiter um sie zu erweitern den Raum des Universums zu schaffen, und hinter sich lassen. Wie kann 'des Universums geworden, was heute ", mit allen seine Masse, durch einen einzigen Punkt? Das Verhalten der Wellen an den Rand des Universums und "anders als das Verhalten von Wellen im Universum, in dem alle Masse und" Wavevolution erstellt von. Die Schöpfung des Universums und "Prozess die ständige Weiterentwicklung, die Wellen beginnt mit der und fährt mit seiner Umwandlung in die ganze Masse, die jetzt vorhanden sind, einschließlich des Menschen. Inside the Universe Wellen ändern ihre Frequenzen auf Widerstand zu stoßen auf ihrem Weg durch andere Wellen, Masse, Gravitation und magnetischen Feldern. Diese Wellen, durch die Interferenz auftritt, weiterhin einen Teil ihrer ursprünglichen Energie umzuwandeln in andere Formen der niedrigeren Energie. Mit anderen Worten, die ursprüngliche Energie, die durch diese Wellen durchgeführt wird allmählich fragmentiert. Für Beispiel Gamma-Strahlen im Laufe der Zeit verringern ihr Niveau von Energie (und Frequenz) auf X-ray geworden, Röntgen-und UV-Strahlen werden so geworden 'für alle anderen Arten von Strahlen. L' ursprünglichen Betrag von Energie ist nicht "verloren, sondern einfach Formen verteilt in verschiedenen anderen. Die Erschaffung des Universums folgt einem Mechanismus die Wellen allmählich Wärme frei, die Beträge" von Energie, original Band und ihre kurz, sie werden länger und länger, die weniger und weniger Energie, als wenn sie ursprünglich gestartet Reisen. Diese Wellen verlieren Energie durch Emission von Wellen in Form von anderen Bands immer größer als der andere. Für eine Länge fast flach (weniger erreicht ein kritisches Niveau von Energie), um die Erstarrung in Wasserstoffatome durch Division ihre Energie (wie die Spitze eines Haares) in seinen beiden gegensätzlichen Elemente:. ein Proton und ein Elektron (nach einer anfänglichen Phase des Übergangs als subatomaren Teilchen) Wenn die Wasserstoffatome durch Hitze miteinander verbunden sind andere, so dass sie erzeugen Mischung miteinander somit "alle anderen Elemente der Masse. Noch heute unterscheidet Wissenschaft der organischen von den anorganischen Masse. Die organische Masse enthält alle Pflanzen-und Tierreich, einschließlich des Menschen (und mehr" Das scheint Leben zu haben). Die organische Masse setzt eine Veränderung und es eindeutig "aus anorganischen Masse, sondern scheint frei von Bewegung und Leben unterschieden. Diese Differenz und" aber "irreführend, da auch Veränderungen bei der Massenbewegung und anorganischen auftreten. Zum Beispiel in Diamanten, die langsam wachsen in der Ausbildung kubische oder in der Saphire statt nach einer Flugbahn Winkel von 60 Grad wachsen zu bilden hex, in Atomen und Molekülen, die ständig bewegen, um sich zu vereinigen und neue Formen der Masse oder sogar in Wellen, die uns umgeben. Das gleiche herkömmliche Definition des Lebens ist immer noch unklar und Klarheit vermissen. Die Tiere leben? Gibt es eine tote Pflanze? Die meisten Menschen betrachten eine klare Definition des Lebens kann nicht sehen, darüber hinaus Pflanzenreich. Aber wenn wir beobachten, nur diese drei Formen des Lebens, dass Menschen, Tiere und Pflanzen, die wir sehen, wie ihre Nenner nur gemeinsame "Bewegung. Aber wenn die Bewegung und das Leben dann ist das Leben" überall in " Universe. Wo außerirdische Lebensformen? Es ist alles um uns herum.

Universum
Der ursprüngliche Sinn von Energie, schaffen 'des Universums kann' auch, dass im Inneren werden im Vergleich zu einem Magneten, wenn "beinhaltet die sowohl positive als auch negative Ladungen. Die Veranstaltung war der Big Bang "als ob der Magnet war von einem Hammer getroffen. Die ursprüngliche Energie" jetzt Elemente aufgeteilt in vielen fragmentierten symmetrisch, jedes Element hat seine eigene magnetisch. Nach der Law of Attraction (Quantenmechanik), die Elemente der entgegengesetzten elektrischen Ladung angezogen zu verbinden, während die mit der gleichen elektrischen Ladung gegenseitig abstoßen eins. In der Tat, wenn wir Magnet versuchte Stück zusammen eine fragmentierte, bemerken wir, dass die Magnetfelder Fragmente bestimmen die Abstände der einzelnen präzise unter den Elementen, ebenso wie mit den Entfernungen zwischen den Sternen.

Kritik Das Konzept der Commutalism Hinblick auf eine neue Form von Demokratie ohne Politiker und durch die Nutzung des Internets.

Comutalismo (dieser Artikel in italienischer Sprache) und auch Kommutalismus dieser Artikel in der deutschen

Bereits im Jahre 42 v. Chr. Cicero sagte: "Eine Nation kann seine Narren, und sogar das ehrgeizige überleben Aber es kann nicht überleben, Verrat von innen ein Enemy at the Gates ist weniger gefährlich, denn er ist bekannt und er trägt seine Fahnen offen, aber die... Verräter bewegt sich unter den in das Tor frei, seinen schlauen Flüstern raschelt durch alle Gassen, in der sehr Hallen der Regierung selbst zu hören. Für den Verräter erscheint nicht Verräter, er spricht in den Akzenten vertraut, um seine Opfer, und er trägt ihr Gesicht und ihre Kleider, und er appelliert an die Gemeinheit, die tief in den Herzen aller Menschen liegt. Er die Seele einer Nation verrottet, er heimlich und unbekannte Werke in der Nacht auf den Säulen der Stadt zu untergraben, infiziert er den politischen Körper, so dass es kann nicht länger widerstehen. Ein Mörder ist weniger zu befürchten. "

Seit Anbeginn der Zeit hat jeder Ideal von den gleichen Krebs, Korruption untergraben worden.

Kommunismus und neuerdings sogar Kapitalismus haben beide als Systeme der Regierung wegen der Korruption und nicht gescheitert, weil diese Ideale waren ungültig. In einem neuen und dauerhaften Form der Regierung Vertrauen kann nicht mehr sein eine ihrer Komponenten. Alle Anstrengungen sollten unternommen werden, um eine neue Art der Demokratischen Regierung mit neuen Mechanismen, die nicht erfordern wird das Element des Vertrauens und noch garantieren lässt den Willen der Mehrheit in die Gesetze dieser Regierung wider bilden. Dadurch wird ein System der Regierung mit immer neuen Mechanismen in der Zeit verbessern die bereits bestehende Möglichkeit, eine Regierung durch das Internet aufgebaut werden.

Das Konzept der Commutalism Hinblick auf eine neue Form von Demokratie ohne Politiker und durch die Nutzung des Internets. In Commutalism, würden die Bürger direkt abstimmen die Gesetze und nicht die Politiker. Solche Form der Regierung würde die öffentlichen Ausgaben für die Politiker und vor allem die Kosten für ihre Korruption. Unterschiedliche Rechts-Boards von privaten Bürgern (jeder Bürger unter wiederum einen Teil der verschiedenen Karten werden) kompostiert könnten für die verschiedenen Vorschläge ernannt. Jede Gesetzesvorlage könnte via Internet eingeführt werden und einer öffentlichen Kontrolle, bevor die Mehrheit der Bürger zu genehmigen konnte oder ablehnen. Eine Police Department ständig wechselnden und kompostiert durch eine größere Zahl von Bürgern (auch unter abbiegen) gebildet, die Gesetze durchzusetzen, wenn durch den einzelnen Bürger gefragt. Monetäre Mittel könnten für verschiedene soziale Programme zugeordnet werden und jeder könnte log in, um die Bilanzen und die Zahlungsfähigkeit dieser finanzierten Programme zu sehen. Alle Gesetze würden in regelmäßigen Abständen überprüft werden, da einige von ihnen fälschlicherweise angenommen werden könnte oder von einer begrenzten Anzahl von Menschen zahlen dann mehr Aufmerksamkeit genehmigt oder vielleicht auch, weil sie nicht im Einklang mit allen anderen Gesetzen bereits genehmigt sind. Jeder Bürger hat das Recht, zu wählen oder nicht wählen zu gehen, aber sein Recht nicht verkauft werden, noch gegeben, niemanden. In Bezug auf die Wahl, würde jede Beschwerde von den Menschen nicht gerechtfertigt, da diese würde entweder Teil einer Minderheit oder wegen ihrer mangelnden Beteiligung an den Wahlen sein. Dieses System der Gesetze würden stets ausdrücklich den Willen der Mehrheit der stimmberechtigten Bürger.

Um das zu erreichen, würden wir einfach zu herrschen, dass alle Menschen genug zu essen und sauberes Wasser für ihr Überleben sind berechtigt. Wir konnten einfach erstellen automatisierten Mechanismen zur Plantagen zu bewässern und wachsen essbare Gemüse gepflanzt, um die Bedürfnisse der weniger privilegierten Menschen zu befriedigen. Diese Plantagen könnten in einigen der vielen abgelegenen Gebieten auf unserem Planeten, die noch nicht aktiv genutzt werden bewirtschaftet. Mit ähnlichen automatisierten Mechanismen dieses Gemüse kann geschnitten, gesäubert, verpackt und transportiert zu werden für den Verzehr bereit. Ein Programm wie dieses könnte durch eine schlossen Aufwand aus der Fülle bereits von der Bevölkerung erworben finanziert werden. Einmal etabliert die Quantität und Qualität aller Waren für dieses Programm benötigt, kann diese Waren in einem Netzwerk von Märkten teilen alle notwendigen Güter, um die natürlichen Anforderungen und liefert in den verschiedenen Standorten zu erfüllen ausgetauscht werden. Dieses Programm (erstellt für jeden zu erhalten) sollte in ständiger Entwicklung, um einen Lebensstandard im Einklang mit der zeitgenössischen Reichtum ihrer Zeit bieten.

Alle übrigen Waren (über denjenigen für die existentiellen Bedürfnisse zu befriedigen) konnte in einer neuen Form des Kapitalismus ausgetauscht werden. Neu und transparent Free Market-Regeln wird für den Handel von allen überflüssigen Waren angewendet werden. In Bezug auf die Übertragung von privaten Gütern oder Dienstleistungen, würde jede einzelne Transaktion müssen im Netz gemeldet werden sichtbar durch jedermann (wie eine Rechnung öffentlich gemacht). Jeder private Transaktion besteuert und gleichzeitig bezahlte mit einem gleichen festen Prozentsatz gilt für alle. In einem solchen System müssen alle privaten Eigenschaften und ihrer Besitzer wie auch alle Geld-Transaktionen und Geschäfte des Privateigentums öffentlich im Netz gemeldet werden. Dies ist in Ordnung zu bringen unerlaubten Geschäften Licht und root die Korruption durch die sofortige Beschlagnahme der Waren, wenn nicht gemeldet. Sobald das Überleben für jedermann gewährleistet ist, wir sollten weniger tolerant mit Verbrechen, als wir es heute sein, wenn es oft durch den Mangel an lebenswichtigen Bedürfnisse getrieben haben. Das Recht auf eigene müssen auch geschützt werden und garantiert für alle diejenigen, die die Zeit ihres Lebens für mehr als nur das Nötigste vom System bereitgestellt Arbeit handeln möchten.

User:Charles Jeffrey Danoff/How-to Build an NBA Dynasty Notes

inspiration for the potential of this work comes from Bill James's early Baseball Abstracts.

Overview
This document is an attempt to collect my thoughts (and hopefully those of many others) on the answer to this question:

 * How do you build a NBA Dynasty?

In October 2010 as part of my work with the Peer to Peer University (P2PU) Fall 2010 Course DIY Math I wrote a post outlining this research, its background and where I might want to go next.

 * Brady said a lot of organizations do not have the competetive stamina the Patriots do, they want 'Victory Monday' off following a win, they don't want to do 2 hour practices on Friday, the patriots don't take any days off. That's what Matt Patricia is trying to do in Detroit, build up those calluses so at times like this (in 4th quarter) it's easy. - Parahprased from Al Micheals and Cris Collinsworth Sunday night broadcast of Pats vs Lions game -- Charles Jeffrey Danoff (discuss • contribs) 02:57, 24 September 2018 (UTC)

 * Kelly was asked how the Eagles' offense could be better without Jackson on the team, and he said, "I don't think our offense has ever been predicated on one player. We used three quarterbacks last year. We used multiple running backs. Our tight ends are integral to what we do. I think we have an outstanding offensive line. It's never been about just one guy. It's why I think we have diversity" on offense, he added. "I mean, we were first in rushing and I think ninth in passing. I think there is balance in terms of how we do things. You want great players at every position, and I think that's what we're always striving for in terms of where we can put people into position. It's never been predicated on just one guy, because if it is, if he's out for a water break or hurt for an extended period of time, then you're going to be in trouble." via http://espn.go.com/nfl/story/_/id/10675583/chip-kelly-noncommittal-desean-jackson-future-philadelphia-eagles --Charles Jeffrey Danoff (discuss • contribs) 16:01, 26 March 2014 (UTC)

"So from that standpoint I think it's very similar to the top college programs. They're year-round programs. I don't think it's any one particular thing that you do, I think it's how you do everything. It's how you approach things."  ""It's not if you trap the pick-and-roll, or you force the pick-and-roll to the baseline, or you blitz and catch and shoot," Thibodeau said. "It's how you conduct your business. What you expect from your players, the professionalism, how you approach each and every day. To put everything you have into it, to play for the team. To put the team first. When you look at the teams that have been able to build over a period of time, they have those characteristics." " --Charles Jeffrey Danoff (discuss • contribs) 06:32, 3 February 2014 (UTC)

 * In the NBA it's more about philosophy: what do I do in a 2 on 1; when do I shoot; when do I pass? Because you don't have time with the 24 second shot clock to call plays. In college with the longer shotclock you can run plays, but in the NBA you need to have guys who understand the team philosophy and can just act with the shot clock winding down.

 * What are the odds you can win a title without superstars?“The chances are, for me, they’re slim,” Ujiri says. “I totally agree that, yes, you have to have one or a couple of those guys, but how do you create it where — I can’t come into Toronto or come into Denver and give the excuse that, ‘Hey, I can’t get any of those guys.’ “So I have to create the environment here. I have to create that environment. It starts with the young players, it starts with the culture you create there, it starts with drafting well. You bring those players, and you attract those players.”

 * Charlotte Bobcats owner Michael Jordan says he's learned to be quicker in admitting mistakes by Rick Bonnell
 * -- Jordan on Michael Kidd-Gilchrist: “He is a hard-working kid. He’s learning on the run. It’s not that he doesn’t have talent. But it’s hard to learn in this (NBA) culture because there are so many games. (Bismack) Biyombo is the same way.”
 * -- He says the biggest thing he’s learned as an owner is to be quicker to admit and correct mistakes. He mentioned the one-season tenure of Mike Dunlap as coach as an example. “I liked Mike, I absolutely did. I said I could have played for him. But that’s not today’s kid. The difference between Steve (Clifford) and Mike is the kids articulate what (Clifford) is saying.”

 * "In terms of the Titans, the onus was probably on them to realize that Johnson might struggle to reach these heights again going forward. They re-signed Johnson, who was holding out at the time, to a four-year contract extension before the 2011 season, which was a full year after his monster campaign. General manager Ruston Webster is admittedly not a numbers guy, and it's not always important for a general manager to be in tune with the numbers, but this was a case where understanding outliers and outlier seasons would have saved the Titans a bunch of money. There's no way they or anybody else would have handed Johnson this contract if they had a second chance. That understanding of outliers isn't a Titans-only issue or even a running back–only problem. It's about mistaking one year of performance as more meaningful than it should be. Statistics reflect performance and help identify the outliers in this context, but having big numbers isn't necessary to join this conversation, to which Dallas's massive contract for left tackle turned right turnstile Doug Free can attest. ... And in terms of Johnson, it's about properly calibrating our expectations. ... That we still wait for Johnson to hit his prior strides speaks to our human nature and the way we interpret growth in young athletes. The reality is that when we expect some players to be hitting their stride and beginning a steady growth process, they might actually be peaking" http://www.grantland.com/story/_/id/9572848/bill-barnwell-looks-numbers-see-chris-johnson-return-record-setting-ways --Charles Jeffrey Danoff (discuss • contribs) 22:49, 17 August 2013 (UTC)

You'd have to be doing drugs to deal for that monstrosity of a contract; I'd need to see one full healthy season from him before I considered it. Could the Chris Paul trade have worked out any worse for New Orleans? They ended up with a possible lemon (Gordon), a few months of Chris Kaman (long gone), a year and a half of Al-Farouq Aminu (leaving after this season), and a lottery pick they turned into Austin Rivers (who generated some 'historically bad' buzz over the holidays before breaking his hand last week).

Teams win championships conventionally (an alpha dog superstar, an accomplished sidekick, a third elite player, than five or six role players) and unconventionally (three or four elite starters who complement each other, then four or five role players), but never radically. The Heat are thinking radically, even if it might not seem like it. They believe two alpha dog superstars -- both perimeter players, both creators who need the ball in their hands, both franchise players who developed particular habits carrying inferior teammates these past seven years -- can reinvent themselves as co-CEOs of a basketball team." from LeBron and Wade: Can it work? 29 Oct 2010
 * Beckley Mason, "The best NBA coaches have a track record of enhancing their players’ awareness. Phil Jackson’s Zen philosophy of being “in the moment” is really about being fully cognizant of teammates and opponents. In Utah, Jerry Sloan’s persistent use of the flex offense has the interesting effect of increasing his team’s collective awareness level. Because they devote so much energy and practice time to one offense, Jazz players are intensely aware of the near infinite permutations of each set, and are focused on reading and reacting. With an internalized, cohesive offensive strategy, Jazz players are able to consistently rise above offensive expectations. See, being aware isn’t just for the greats, it’s also how bad players become average and mediocre players become Kevin Martins. In short, it’s how a player maximizes his potential." from On Awareness: The Intangible Skill That Makes All The Difference November 19th, 2010
 * must a dynasty necessarily include something new, that couldn't be predicted by a mathematical equation. like a new pop hit needs to have something fresh to catch that is inspired by what came b4, but also not able to be predicted. e.g. jordan being first 2-guard led dynasty. \

 * Ben Golliver "Walk like a GM, talk like a GM" March 10, 2011 @ 6:29 pm "We have looked at three thoughts. First, that the NBA trade market is not nearly as efficient as it should be, but that analytics may help improve that. Second, that the short-term pressure on NBA GMs to win big is enormous and that some GMs have shifted course to focus on risk assessment so that they can swing for the fences when necessary. Third, that NBA executives are feeling limitations in their ability to use analytics to gain an advantage during the draft process and that non-quantifiables such as work ethic and dedication remain undervalued assets.

Taken together, we’ve reached a point where we can officially declare that the honeymoon period is over for the cult of advanced statistics in basketball. ... The message from the 2011 Sloan Conference, then, wasn’t the same as previous years: It wasn’t a declaration of arrival, a celebration of newfound success or even an admission of early struggles. Rather, it leaned more towards a high school reunion, where the like-minded from around the country, now fully content and secure with their place at the table, gathered to swap stories and best practices in front of a rapidly growing crowd of followers, anxious to learn how they might grab their own seat.

Havoc
Coach Smart's teams play a style of basketball known as "havoc". Smart described his "havoc" defensive philosophy during his introductory press conference as, "We are going to wreak havoc on our opponent's psyche and their plan of attack." On the court, the "havoc" defensive mindset is visible through the heavy use of the full court press and pressing after made baskets to disrupt opponent's timing of offensive sets. In his second season, VCU led the Colonial Athletic Association in steals. Offensively, Shaka Smart-coached teams play uptempo and push the ball after misses and makes with what Smart describes as, "The freedom to make plays in the open court".

Ideas in Geometry/Instructive examples/Section 2.1 Basic Set Theory number 10

Ặ== Section 2.1 Basic Set Theory number 10 == Prove that XU(Y∩Z)=(XUY)∩(XUZ) Smoo1244 03:33, 22 October 2010 (UTC)

Definition: A set's any collection of elements for which we can always tell whether an element is in the set or not Definition: Given two sets X and Y, X union Y is the set of all the elements in X and all the elements in Y. We denotes this by XUY. Definition: Given two sets X and Y, X intersect Y is the set of all the elements that are simultaneously in X and in Y. we denote this by X∩Y. Now to find the left side, we know that X is union to Y intersection Z. This means, that everything is in X and the elements intersecting at X and Y.

On the other right side of the equation, the elements are in the intersection of X union Y and X union to Z. If we were to make a diagram of X union Y and another diagram of X union Z, we would see that X Union Y is everything in X and Y, similarly, X union Z is everything in X and Z. If we were to combine these two diagrams together, we see that the diagram looks exactly like the left hand equation, XU(Y∩Z)

I like your overall explanation of the problem. It would also be better if there were some pictures involved so that it would be easy to know what the problem looks and like and it would be easier to follow along. Also, If you could discuss the basic definitions involved in the beginning of your paragraph, that would be easier to relate to your problem better. Like the definition of what probability is and other basic definitions students who have never taken this class would need to know in order to figure out this problem

-Suzie Moon Smoo1244 04:14, 27 October 2010 (UTC)

You definitely did a good job explaining why you need to do the formula for the problem. Maybe what you could do is write out the formula and how you solved it all with the math and algebra out underneath. Or like suggested above, include a picture. But we definitely need to see all the work that is done to finish this problem to understand how you got your final answer, not just skipping there, but all the intermediate steps too.

I like your pictures of the answers, but I think it would be best to have an actual discussion with words about your problem. You should write the steps out that you did with the pictures so students that have never taken this class can follow along also. Also, you should write the definitions that one may need to know in order to solve this problem, such as what a union is and a intersection is in the beginning of your discussion.

Relational Databases/Introduction

Introduction
Relational databases are a common and powerful approach to storing information. They make efficient use of computer storage by connecting sets of data together. In this course we are going to engage in a quick introduction to relational databases, starting from the basics of how they work and finishing at a point where the reader should be able to build their own simple database in an SQL-based relational database management system (RDMS), such as MySQL, SQL Server or PostgreSQL.

Some background: how data is stored in a flat file database
I would like to propose a simple database: a small database for a personal library, where I hope to keep track of who has borrowed my books. To do so, I want to keep track of:

 * Borrower's name
 * Borrower's email
 * Borrower's phone number
 * When the book was borrowed
 * Title
 * Author
 * Year published

Of course, a more complex database would store more data, but for a personal library that might be enough. This will let me know what the book is, (title, author and year of publication), who has it, when they took it, and how to contact them in order to ask for it back.

One method of tracking of these records is a spreadsheet. In a spreadsheet, each column could represent one of the fields above, while each row would cover one of the records. For example, I could use:

This is what is commonly referred to as a flat file database: a database in which all of the data is kept in a single file. It has the advantage that it is relatively easy to use. If I wished to know what book Alex had borrowed, I could quickly scan through the names column until I found Alex, then read across to find the title. Similarly, a computer could check the first column of each row until it found the desired name, and then quickly output the title of the book. There is a bit of a speed hit if there are a lot of records, as it could take a while to scan a file consisting of tens of thousands of entries, but I would get there in the end. And if needed, I could always optimise the data: for example, I could order the records by the name of the borrower or the title of the book, which would make searching even faster if I was only looking for one of those two fields. Thus flat file databases are useful where either speed (given certain constraints) or simplicity is a concern, especially when the data set can be well defined and is small, or where searches are limited to just one field in an ordered set.

However, the limitations of this approach quickly become apparent. For example, what if Alex borrows two books at once? There are two options:

 * 1) Create a second record, repeating all of the information about Alex
 * 2) Add more columns to allow for more books

The first option creates:

Unfortunately, this introduces a number of concerns, although for now the focus on but two. First, by repeating data, the possibility of errors has increased. Every time the same information has to be entered, there is a chance that something will go wrong. And this problem becomes worse when Alex's details need to be updated, as those details must be updated in every one of the rows related to Alex. Databases need to be reliable, and anything which can increase the possibility of errors is a bad thing. Second, it wastes memory. The system already has Alex's details on record – now it has the same data twice, using up twice the memory.

Alternatively, more columns be added per record:

This makes the risk of errors smaller, but it is still wasting memory: all of those empty fields take up memory in the database, and most of them are unused. (Many databases will reserve a certain amount of memory per field, irrespective of what is actually in it – variable width fields do exist, but many fields are not variable, and even those that are have to commit some memory to the task). Plus, what happens if Alex now decides to borrow a third book? I could add a third set of columns, but then the memory usage is even worse - and, of course, that places a limit of three books per user. What if someone wants to borrow four?

Thus it is time for an alternative approach.

An alternative approach
If we stop thinking about computers, and instead think about how this would be handled this in real life, it seems that the solution is simple: create two sets of records. One as a list of "borrowers", containing their names, email addresses and phone numbers, and a second containing a list of books with the names of those who borrowed them. Implementing this using the above data, we get:

This is much more effective that the flat file database: it has the potential to use less memory (although there is a need to include the borrower's name in two places); there is less information being repeated; and there is no limit as to how many books someone can borrow. There is a cost, of course: using it has become harder. For example, to find out who to ring to chase up a copy of The Time Machine, I would need to look in the list of books, find it, read the name of the borrower, then scan the list of borrowers until I find their name and look up their phone number. Not impossible, but certainly more difficult than with the flat file. (Doing this, in the language of relational databases, is called "joining" the two tables, and results in a speed hit).

There another problem, though. What would happen if there were two people called Alex? In such a situation, the system would collapse: there would be no means of telling if the Alex referred to in the books table is the first Alex in the borrowers table or a different Alex. The name is not sufficiently unique to identify all of the potential people who could borrow books. What is needed is something unique - a code to represent each borrower that would be different for each one. This, in computing terms, is called a unique identifier, and in databases a unique identifier can be a primary key (PK): a unique code that is the primary means of identifying a record in the database. A common example is the registration number for a car, or an ID given to each student at a school.

The simplest solution to creating a unique identifier is to just number each record, using a numeric sequence starting at 1. Doing so will provide the unique identifier that the database needs, but it also has a neat side-effect: in computing numbers are generally much smaller than names, and thus the result is a reduction in how much memory is required to refer to the different records.

This does make it a bit harder for people to read, perhaps, but computers won't suffer from the same problem. They can handle the numbers as easily as they can handle words.

Expanding the model
This is good, but it is still not perfect. One problem is that there is no way of knowing who borrowed the book last – the system doesn't retain a borrowing history. It has the date the book was borrowed on (which will presumably be blank if it has been returned), but as there is only one date box, we need to overwrite that date each time it is borrowed.

On solution to this problem could be to modify the "Books" list. For example, we could add a "returned" column so we know when it came back, and just add a new record when it is borrowed again.

However, now there is the same problems as before: data is being repeated, which is both risky (because of the possiblity of errors) and wastes memory.

So, how about an alternative? The solution last time was to create a new list. How about separating the dates, borrower IDs and dates returned from the books list, and placing it in one of its own?

It is true that this does not make it any easier for people to work with – now they have to scan through three lists to work out who has borrowed a book, and they need to check to see if it has been returned as they go – but this has reduced the incidence of repeated data, improving the reliability and potential size of the system. Reliability is one of the primary priorities for database design.

Bringing it together
This final design is a relational database. Indeed, the design could be readily implemented in a relational database such as MySQL, Oracle, Microsoft Access or SQL Server with no significant modifications at all. The "relations" part of the "relational database" name comes from the IDs: the Books list is related to the Loans list by the Book ID, and the Loans list is related to the Borrowers by the Borrower ID. There is still room for some refinement, but if you can understand how these lists (or "tables" as they should be called in a database) relate to each other then you've passed the biggest hurdle.

Tasks to try
After the above discussion, we now have a basic database consisting of three tables and a number of records:

Using these tables, there are a number of things you can try.

Question 1
When was "The Time Machine" borrowed?

Looking in the Books table, the ID of "The Time Machine" is "3". Looking up 3 in the Loans table under "Book ID" reveals one record, which confirms that the book was borrowed on 1 March 1971.

Question 2
How many books has Alex with the email address otheralex@internet borrowed?

There are two people with the same name, Alex, so relying on the name wouldn't be enough. However, using the email address, the Borrowers table reveals that the Alex with that email has the ID of 4. Looking at the Borrower ID column in the Loans tables reveals that there are no loans for a person with the ID of 4. Therefore, Alex with the email address otheralex@internet has not borrowed any books.

Question 3
Who has borrowed the copy of H. G. Wells' "The War of the Worlds".

Looking in the Books table, the ID of "The War of the Worlds" is "2". Looking up 2 in the Loans table under "Book ID" reveals two records. However, only the second record shows that the book hasn't been returned, and that is by a borrower with the ID of "3". Checking the Borrowers table reveals that the borrower with that ID is Kim.

Therefore Kim currently has a copy of the book. Given that Kim borrowed it in 1971, it is probably overdue.

Question 4
How many books Kim has currently borrowed.

Kim's ID in the Borrowers table is "3". There are two records in the Loans table for someone with that ID, neither of which has been returned. Therefore Kim has borrowed two books. (Note that there was no need to look into the Books table).

Question 5
What would you need to change in the database in order for Sam to return her book, and for Kim to borrow it after her.

You would need to change the record in Loans representing Sam's loan (Borrower ID 1, Book ID 1) to include a return date, and then add a new record to the Loans table, with the book ID (1), Kim's ID (3), and the date the book was borrowed.

Technically you could do this without accessing the Books table, but you would need to find out both Kim and Sam's IDs from the Borrowers table.

Question 6
Add a new borrower (Jim, jim@internet, ph 9876-5432) and a new book (Dracula).

Add to Borrowers:

Technically you could use any ID not currently being used, but it is easier just to go with a sequential number, as that way it won't repeat. To the Books table, you need to add:

Question 7
Make a new table ("Authors") to contain a list of authors, and relate it back the "Books" table. (This one is more challenging, but would be a good step towards understanding relational databases).

You will need to make two changes. First, create a new Authors table consisting of Name and ID:

Then you need to adjust the Books table to use an Author ID rather than an author's name:

This will,once again, make it more difficult to find data, as you need to join more tables together. But it means that you only need to spell an author's name correctly once, and it uses less memory (so long as enough authors have written more than one book in order to make it worthwhile).

Next steps
Once this makes sense, as I hope that it will, it is time to move on to looking at how to design a relational database.
