<content:encoded><![CDATA[<p><a href="http://teachingphysics.files.wordpress.com/2008/07/phun-1.jpg"><img class="alignright size-medium wp-image-136" src="http://teachingphysics.wordpress.com/files/2008/07/phun-1.jpg?w=180" alt="" width="258" height="174" /></a>I just found this package through some random surfing.  It's called <strong>Phun</strong> and it's a simple graphical world builder with a real physics engine underneath.  There is a decent online tutorial and a pretty decent online community to share ideas and solve problems.  The download is only 2.8MB, it loads up fast and easy.</p>
<p>Phun can be found here:  <a title="Phun" href="http://www.phunland.com/wiki/Home" target="_blank">http://www.phunland.com/wiki/Home</a></p>
<p>The software was created by Emil Ernerfeldt as part of his masters thesis at Umea University.  He calls it a 2D Physics Sandbox and I can see why.  You want to take yours shoes off and just play in it all day.  Since its creation, Emil has gone to work for a software company where he continues to develop Phun.</p>
<p>Phun is free for an individual to use, but not free for commercial use.  Emil made it clear, however, that Phun is free for educational use.  I plan to install in on the computers in my classroom and give assignments and perhaps extra credit for designs that demonstrate the principals we are working on in class.  There is no reason why my students can't install the software at home and bring in their creations.</p>

<content:encoded><![CDATA[<p>O nome do jogo é <a href="http://www.kloonigames.com/blog/games/crayon">Crayon Physics</a>. O objetivo é coletar as estrelas, empurrando a bolinha, desenhando quadriláteros (!) ou linhas que respeitam as leis da física (eles caem!!).<br />
Viciei totalmente. É fácil, dá pra zerar muito rápido (mas a cada vez que você joga pode descobrir novas formas de chegar às estrelinhas) e aí você ganha um level de bônus onde pode brincar livremente.<br />
<img class="alignnone" src="http://img530.imageshack.us/img530/286/crayonqs2.jpg" alt="" width="500" /><br />
Parece um pouco com o <a href="http://www.phunland.com/wiki/Home">Phun</a>, um aplicativo divertidíssimo que também conheci há pouco tempo, mas com menos recursos (ah, mas no Phun você não coleta estrelinhas!!). No Phun você pode construir máquinas, motores, mexer na gravidade, no atrito e até usar água e vento.<br />
Vai um vídeo então do programinha mágico:<br />

<span style='text-align:center; display: block;'><object width='425' height='350'><param name='movie' value='http://www.youtube.com/v/3nSpSNb9a5'></param><param name='wmode' value='transparent'></param><embed src='http://www.youtube.com/v/3nSpSNb9a5&rel=0' type='application/x-shockwave-flash' wmode='transparent' width='425' height='350'></embed></object></span></p>
<p><strong>Why?</strong><br />
My physics teacher recently broke his wrist/arm/something, and as there are only a few physics lessons left before the summer holidays (at time of writing: 2) we won't be getting another teacher. Instead we were set work to 'investigate the forces on a 70kg person on a fairground ride' - a poor attempt at compensating for the theme-park trip missed as a result of the broken bone (he was going to drive us). This led me and friends to have a play with phun, to produce some fairground-ish rides, of which the 'Big Dropper' was the most successful.</p>
<p>The video was recorded<!--more--> using <a href="http://recordmydesktop.sourceforge.net/about.php" title="Record My Desktop">RecordMyDesktop</a> after having tried several other programs which failed to do the job - xvidcap and glc both failed to record a decent video. RecordMyDesktop produced an Ogg Theora format video which I then uploaded straight to youtube.</p>

<content:encoded><![CDATA[<p><a href="http://murdersherote.files.wordpress.com/2008/07/rbon53ljpeg.jpg"><img class="alignleft size-medium wp-image-330" src="http://murdersherote.wordpress.com/files/2008/07/rbon53ljpeg.jpg?w=226" alt="" width="226" height="300" /></a>Everyone's had one. Some people have two or more if they are famous. I had one and it freaked me out for a long time. I bought my first cell phone because of it.</p>
<p>Stalkers. Creepy, weird, and generally socially inept with a bit of malfunctioning chemical hard-wire.</p>
<p>After I graduated from high school, I moved to the nearest city and lived and worked for a year before deciding to go to university (something I highly suggest if you are broke and really don't know what you want to do with your life).</p>
<p>The day after I moved to the city, I started my new job, working in a pharmacy, in the back where the action happens: the drug dispensary.</p>
<p>I have maaaannny stories about working in pharmacies (I worked as a Tech for 5 years), some funny (I took a call once, where the guy on the other end told me seriously without laughing, that his penis was too big for even the Magnum sized connies and what should he do - I was laughing too hard and had t pass it to the pharmacist), gross ("Pharmacist, I haven't taken a dump in a week, what can I take?), NSFW gross ("Um, so I have this strange fluid leaking from my anus..." - I'm not even kidding people, if you want to go into pharmacy, have an iron stomach because people come in there as if they are talking to their doctor, no one hides anything). There was also the d-bag who would hit on me everytime he came in to fill his Valtrex (herpes medicine) as if I didn't know what it was for. Ew. Ew. No.</p>
<p>But there is only one creepy story.</p>
<p>About two months after I was hired, I got a strange call at work.</p>
<p>"Hello", I answered.</p>
<p>"Um, hi, you don't know me, but I know you [I swear to god, he said this]. I have been watching you" [ack, creep alert!], he told me.</p>
<p>"Who is this? Tom if this is you, I swear to Lucifer, I will melt down your motherboard when I get home!" I spat into the phone. (At the time, I was living with 3 guys, one of whom was my boyfriend at the time. Yeah, I know how crazy this sounds. They were messy and dirty, but that's another post).</p>
<p>"Oh, uh, no, no, you have never seen me in person, I come in to fill my prescription and I have seen you a couple times and you look like an angel. I was wondering if you were interested in being my friend?"</p>
<p>"Uhhhh, that's not a good idea, I am flattered but, uhhhhhhh, I have to go." And I quickly made "busy" noises (slamming things, tapping on the computer keys) before hurriedly hanging up the phone. [SHUDDER]</p>
<p>I was thoroughly freaked out by the fact that he had been watching me, looking, staring, observing from afar, yet I didn't know what he looked like, except that he had the stalker-talk down to a movie script finesse. 'You don't know me, but I know you' and 'I've been watching you' - dear.god</p>
<p>I told my boss and my co-workers about it and they told me not to walk home alone (which I did because I lived close by), and to think about getting a cellphone (which I did not, until my mom threatened my life until I bought one so she could talk to me every night for a month while I walked home after work).</p>
<p>It didn`t end there.</p>
<p>No, he called the next day, and the next, until after losing sleep for a couple nights, I got on the phone and told him that no, I didn`t want to be friends, that his whole approach had made me uneasy and that should he call me again, I would contact the police and set about getting a restraining order.</p>
<p>He quietly said that he understood, which made me feel really guilty, but at the same time, I felt scared and stressed out, and no friendship or relationship should ever be founded on either of those things. So he left me alone and the calls stopped, though to this day, I never found out what he looked like, never met him in person, and completely forgot all about him.</p>
<p>Until the scary Tylenol 3 addict who forged doctors prescriptions, showed up and refused to leave the store, making my stalker seem friendly and harmless in comparison. Stay tuned for more pharmacy phun.</p>

<p>Current (visual) mood of how I feel internally.  I want to write, but I am super exhausted, yet super happy and at peace (liek teh kittah).  The reason?  Children's church tonight.  If you ever serve in any ministry, I say consider Children's ministry; it'll change your life!  Sure, the kids and activities can drain the energy right out of you, but once you see the work God does in the live's of His children, you will give yourself to exhaustion willingly!  There's nothing more heart- (warming, changing, captivating, ________, ) than seeing the joy and hope in the eyes of children that look forward to being in God's house and being themselves while discovering who God has called them to be.  They're not likely to say this directly, but like I said, you see it in their eyes, feel it in their spirit, hear it in their inflection,... you just know.   And to top all that off, it is just plain F-U-N !!!  (or as Pastor Sarah would say, "PHUN").  But don't take my word for it, come see for yourself!  You'll be amazed!</p>

<content:encoded><![CDATA[<p>Just a quickie for all y'all who missed the raucous pho night on Sun!  We had a blast!!!  Nathan Malone has moved beyond a pho apprentice into the Master realm for ingesting a durian boba - ask him, that's all I'm saying.  The delightful Allan Pan graced us with his presence, &#38; humor, the delightful Gallant couple was truly gallant, Chelps drove in early from Kansas to make the evening (pho or kansas?  that's a toughie), Justyn Regan was mighty in wit, Zach Hilbrich was as clever as always and the color of Bryan Kinney's pho matched his hair (kind of orangish red).  Anyways, if you missed having phun with us, then make it a priority to be there the next time.  I'll give you plenty of warning!</p>
<p>We had a blast &#38; the only way it could have been more phun is if you had been there.  :)  Now while pho may not be your bowl of noodles / cup of tea, its all about the people - so just come &#38; have an iced coffee, salty lemonade, or whatever &#38; enjoy the comphany!  Its wonderphul! ;)</p>

<content:encoded><![CDATA[<p>Gisteren eindelijk eens tijd gevonden om phun te testen. Het programmaatje om te experimenteren met fysische processen waarover ik eerder schreef. Het downloaden verloopt zeer vlot en de installatie vraagt ook amper kennis van zaken. Met andere woorden kon ik ongeveer twee minuten na de start van het downloaden, het programma effectief gebruiken.<br />
Wat mij opviel was het intuïtieve design. Er staan enkele mogelijkheden aangegeven en met klikken en slepen maak, verplaats en verwijder je heel eenvoudig objecten. Met de rechtermuisknop kan je dan heel veel opties van deze objecten aanpassen. Zo kan je vaste objecten vloeibaar maken, het soortelijk gewicht en de veerkracht aanpassen. Ankerpunten kunnen fungeren als motor die je een bepaald toerental en een bepaalde kracht kan meegeven.<br />
Het programma is beschikbaar in het Nederlands waardoor het zelfs bruikbaar is om in de lagere school mee te werken. Ook heel leuk zijn de beschikbare modellen. Deze pagina's zijn leuk opgevat en geven ook een snel overzicht van een aantal van de mogelijkheden van het programma.<br />
Ik denk dat kinderen hier snel mee kunnen leren werken en dat het hen kan helpen om bepaalde processen te leren begrijpen. Zo zullen ze bijvoorbeeld het drijfvermogen van verschillende vormen kunnen testen en spelen met het soortelijk gewicht of de wrijving. Ook kunnen ze experimenteren met bijvoorbeeld de kracht die een motor zal moeten bezitten om een voorwerp met bepaalde eigenschappen te bewegen.<br />
Dit zijn maar enkele manieren om te werken die onmiddellijk in mij opborrelen. Verder is het ook gewoon een leuk spel om te zien hoe voorwerpen zich gedragen wanneer ze aan kettingen en veren opgehangen worden en er andere blokken worden op gestapeld.</p>

<content:encoded><![CDATA[<h2>Are you having Phun Yet?</h2>
<p>In my last Post I mentioned the incredible physics sand box or physics reality simulator <a href="http://www.phun.at/">Phun</a> . Here I will explain in some detail one scene created with Phun.<br />
When you build physical simulations in Phun you are creating a visual representation that is  attached virtually near physical behavior.  In a way you are actually building graphically a very sophisticated computer program where each element have physical properties. Like being able to move, collide, bounce, gravity, velocity, acceleration etc. Naturally the simulation is no perfect but is very close to reality and that is what makes it very surprising and I believe useful. It's almost like using Lego blocks but this time you can build the building blocks by yourself!</p>
<p>I will name the process of building scenes "<em><strong>Phun programming</strong></em>" for the above reason and by extension a Phun programmer is he who creates a scene.</p>
<p>While many of the Phun programmers restrict them self to creating rockets and tanks some others have dedicated their time to create ingeniously intricate mechanism.  I am still in complete awe by some of the mechanical things that people have created with Phun. Between those prolific creators I have found Livio Zucca from Turin Italy the home of world fame mathematician <a href="http://en.wikipedia.org/wiki/Giuseppe_Peano">Giuseppe Peano</a>. I believe Livio's creations deserve more attention for his ingenuity.</p>
<p>In my prior post about the <a href="http://blog.isallaboutmath.com/2008/05/18/pascals-triangle-and-phun-computer/">Pascal triangle with Phun</a> I extended a prior idea from Livio.  The machine in question is a binary mechanical counter.</p>
<p style="text-align:center;"><img class="aligncenter size-full wp-image-54" src="http://isallaboutmath.wordpress.com/files/2008/06/liviosbinary1.png" alt="" width="311" height="241" /></p>
<p>The main component to perform computations in this particular device is what is know as a <a href="http://en.wikipedia.org/wiki/Latch_%28electronics%29">latch</a> and it should not be confused with a <a href="http://en.wikipedia.org/wiki/Flip-flop_%28electronics%29">flip-flop</a>. The main difference between latch and flip-flop is that latches are transparent storage elements while flip-flops are not. Wikipedia point out this new distinction.</p>
<p style="text-align:center;"><img class="aligncenter size-full wp-image-54" src="http://isallaboutmath.files.wordpress.com/2008/06/liviobinary12.png" alt="" width="370" height="305" /></p>
<p>In the above picture you can see a magnified section of the machine. This we called the <strong><em>ball feeding mechanism</em></strong> and it's function is to collect balls and feed them up the  two dimensional vertical tube on the left.</p>
<p>Let us explained in a bit of detail how this is achieve with Phun.</p>
<p>In Phun you can simulate gravity and can also simulate movement. You can define two types of hinges. The normal kind that is just a hinge that hinges and there is the one that can act as an engine or motor. This is just a programmatic simplification on Phun's designer part. It will be nice if there was some visual differentiation between them but at the moment there is none.</p>
<p>The crosses are used to attached things so they will not fall off the scene when gravity acts upon them.<br />
Notice the green bar at the bottom of the picture. That bar acts as the collector of balls and it does have a very slight inclination this is useful in this design as it makes the balls roll slowly towards the left where the feeding mechanism is located.</p>
<p>You can also see a spring and I guess you must probably already know what a spring does!</p>
<p>and at last the actual latch</p>
<p style="text-align:center;"><img class="aligncenter size-full wp-image-54" src="http://isallaboutmath.files.wordpress.com/2008/06/liviobinary13.png" alt="" width="290" height="125" /></p>
<p>The latch acts like a <a href="http://en.wikipedia.org/wiki/Weighing_scale#Balance">balance</a> and there is a hinge that can be visible if you magnify the picture a little bit more. The numbers have a double function in this particular case. They act as stoppers for the balancer and also as indicators of the state of the latch. As portrait above this latch is in 0 state.</p>
<p>As you probably know latches have two states. One can be use to represent 0 state as in this case and the other can be use to represent 1.</p>
<p>The latch alternates between this two states as you can see in the animation below.<br />
You may also appreciate the mechanism for translating circular motion into linear upward motion on the left side. This mechanism brings back memories of the mechanism that provided steam locomotive with motive power in time past.</p>
<p>As you may have already guess by the picture of the machine and the name the function of this particular mechanism is to count balls dropping down from the device and this is done using the <a href="http://en.wikipedia.org/wiki/Binary_numeral_system">binary numerical system</a>. The binary system is a numerical positional system that uses only two digits instead of the 10 digits we use in our decimal numerical system.</p>
<p>For educators Phun will be a source of inspiration. I believe it is very useful for the instruction and motivation of Mathematics,Physics, Computer Science, Mechanical Engineering,Electronics. Phun is opening a new universe of interactive learning and should I dare also say FUN!</p>
<p>If you like to play,run or modify the Scene above in the Phun simulator you can download the Phun program and the scene from</p>

<content:encoded><![CDATA[<p>Im Zuge meiner wissenschaftlichen Hausarbeit habe ich mich mit Lernsoftware befasst und möchte dazu das Tool Phun vorstellen. Vorweg: Im Moment macht es eher den Eindruck eines "Spielzeugs", (wie man auch bei zahlreichen <a href="http://www.youtube.com/results?search_query=Phun&#38;search_type=" target="_blank">Youtube-Videos</a> das Gefühl gewinnen kann), weshalb mich hier in erster Linie der Einsatz zu Lehr- und Lernzwecken interessiert. Vielleicht können wir hier nach der Vorstellung des Programms einige Ideen sammeln:</p>
<h3><span style="text-decoration:underline;"><strong>Allgemeine Angaben:</strong></span></h3>
<p><strong><em>Name:</em></strong> Phun - the 2D physics sandbox<br />
<strong><em>Hersteller / Vertrieb:</em></strong> <a href="http://phun.cs.umu.se/wiki/emilk" target="_blank">Emil Ernerfeldt</a> / VRLab, Umeå University, Sweden<br />
<strong><em>Website:</em></strong> <a href="http://www.phun.at/" target="_blank">http://www.phun.at/<br />
</a><strong><em>Getestete Version:</em></strong> 3.5 beta<br />
<em><strong>Typ:</strong></em> Simulation<br />
<em><strong>Fach / Zielgruppe:</strong></em> Die Software eignet sich hauptsächlich für Physik, speziell im Bereich Mechanik, und technische Fächer, eventuell können durch die freien Gestaltungsmöglichkeiten noch andere Fachrichtungen einbezogen werden.<br />
<strong><em>Einsatzort:</em></strong> In der Schule zu Demonstrations- und Versuchszwecken, aber auch als "Spielzeug" zuhause.<br />
<strong><em>Preis / Lizenz:</em></strong> Freeware für nicht-kommerzielle Zwecke, näheres <a href="http://phun.cs.umu.se/wiki/Download" target="_blank">hier</a>.</p>
<h3><span style="text-decoration:underline;"><strong>Technische Angaben:</strong></span></h3>
<p><em><strong>Betriebssystem:</strong></em> Windows XP und früher, Windows Vista, Linux, MacOS ab Version 10.4, läuft auf x86 und PowerPC<br />
<em><strong>Minimale Hardwareanforderungen:</strong></em> "bescheidene" Rechner, Grafikkarte mit 3D-Unterstützung<br />
<em><strong>Zusätzlich benötigte Software:</strong></em> keine Angaben</p>
<h3><strong><span style="text-decoration:underline;">Inhalt und Ziel:</span></strong></h3>
<p>Phun lässt sich zurecht als virtueller Sandkasten bezeichnen, der ein neues Projekt lediglich mit einem blauen Himmel präsentiert, durch den träge kleine Wölkchen treiben. Nur mit einem Zeichenstift und einer Werkzeugleiste ausgerüstet kann der Anwender hier seiner Kreativität freien Lauf lassen. Welche Möglichkeiten sich hierdurch ergeben zeigt eindrucksvoll ein Beispielvideo des Herstellers:</p>
<p><span style='text-align:center; display: block;'><object width='425' height='350'><param name='movie' value='http://www.youtube.com/v/0H5g9VS0ENM'></param><param name='wmode' value='transparent'></param><embed src='http://www.youtube.com/v/0H5g9VS0ENM&rel=0' type='application/x-shockwave-flash' wmode='transparent' width='425' height='350'></embed></object></span><br />
(Verwendung mit freundlicher Genehmigung von Emil Ernerfeldt)</p>
<p>Phun eignet sich zum kreativen Experimentieren mit mechanischen Eigenschaften. Hierzu erschafft sich der User seine Experimentiergegenstände und -umgebung komplett selbst. Dies können einfache Klötze bis hin zu komplexen Maschinen sein. Dabei werden die Grenzen (fast) nur von der eigenen Phantasie gesteckt. <a href="http://www.youtube.com/results?search_query=Phun" target="_blank">Youtube-Videos</a> von Usern zeigen, was sich mit Phun etwa realisieren lässt.<br />
Die Einschränkungen liegen in den zur Verfügung stehenden Materialien begründet. Körper lassen sich frei mit dem Pinsel zeichnen, daneben gibt es von Zeichenprogrammen her bekannte Werkzeuge zum Erstellen von Rechtecken und Kreisen, auch Federn, Ketten und Gelenke sind möglich. Leider fehlen zum Beispiel Seile im Repertoire. An manchen Stellen lassen sich diese eventuell durch Ketten ersetzen, aber im Test waren sie beispielsweise für einen Flaschenzug mit zwei Rollen ungeeignet.<br />
Daneben lässt sich mit Phun nur qualitativ aus Beobachtungen heraus arbeiten. Messgeräte, etwa einen Kraftmesser, gibt es nicht.</p>
<h3><strong><span style="text-decoration:underline;">Lernmotivation / Interessenförderung:</span></strong></h3>
<p>Der große motivierende Aspekt des Programmes ist die völlige Freiheit. Das Programm gibt mit Ausnahme seiner Funktionen im Grunde nichts vor. Der Kreativität sind somit nahezu keine Grenzen gesetzt. Setzt man die Software als Experimentierumgebung im Unterricht sein, so sollte man diesen Aspekt nicht außer Acht lassen. Der Lehrer kann natürlich das Experiment bereits vorbereiten, was Zeit spart und die Schüler ein wenig an die Hand nimmt. Phun aber bietet da Möglichkeiten, die ein einfaches Experiment erweitern können. Etwa kann eine zusätzliche Aufgabe sein, den Versuchsaufbau zu optimieren oder mit selbst kreierten Versuchsmaterialien zu wiederholen. Wurde nichts vorgegeben, können Wettbewerbe veranstaltet werden. Die schönste oder zweckmäßigste Versuchsanordnung kann dann prämiert werden, was zusätzlich motivierend wirkt.</p>
<h3><strong><span style="text-decoration:underline;">Lernunterstützung:</span></strong></h3>
<p>Durch seine Offenheit unterstützt Phun genetisches Lernen. Die Schüler können, wie schon erwähnt, selbstständig am Versuch arbeiten und diesen bei Bedarf komplett verändern. Sie können zusätzliche, ihnen geeignet erscheinende Materialien einbauen oder entfernen, können Reibungswerte verändern und noch vieles mehr. Der große Vorteil ist dabei die direkte Visualisierung der Ergebnisse. Die Software beschränkt sich dabei auf deine zwei-dimensionale Darstellung. Sie kann sowohl zur einfachen Veranschaulichung, etwa als Simulation oder "Lehrerexperiment" dienen, als auch als Experimentierumgebung für die Schüler. Dabei muss der Lehrer stets abwägen, in welchem Maß die Software zur Verdeutlichung eines Inhaltes auch einsetzbar ist. Mit Phun kann etwa ein Ottomotor schematisch gebaut und die einzelnen Phasen darsgetellt werden. Wäre es nicht besser, hierfür eine bereits existierende Animation zu nehmen, die speziell für diesen Zweck entwickelt wurde (wie etwa bei <a href="http://de.wikipedia.org/wiki/Ottomotor" target="_blank">Wikipedia</a>)? Einfache Reibungsexperimente lassen sich auch mit kostengünstigen Materialien druchführen. Welche Vorteile bietet dabei die Software? Ein Einsatz des Programms ist daher stets abzuwägen, was aber prinzipiell für jeglichen Softwareeinsatz gilt.</p>
<h3><strong><span style="text-decoration:underline;">(Zusammen-)Arbeiten mit der Software:</span></strong></h3>
<p>Beim Start präsentiert sich die Software in englischer Sprache, welche sich aber leicht auf Deutsch umstellen lässt. Der User hat die Möglichkeit, die Auswirkungen seiner Arbeit in Echtzeit zu verfolgen oder aber er baut und platziert seine Konstruktion erst in völliger Ruhe zusammen und startet abschließend die "physikalischen Gesetmäßigkeiten" durch einen Klick auf den grünen Start-Button.<br />
Die Bedienung ist intuitiv und durchdacht. Die Icons sind nahezu selbsterklärend und auf ein überschaubares Maß reduziert. Neben dem üblichen Laden und Speichern, den Optionen, um Feinheiten am Programm vorzunehmen bildet die Werkzeugleiste ein zentrales Element. Für gezeichnetete Objekte können mit einem Rechtsklick noch weitere Optionen individuell eingestellt werden, etwa ob ein Gelenk automatisch rotieren soll, welche Reibung der Körper besitzt und dass sich das eben gezeichnete Objekt in Wasser verwandeln soll. Hinzu kommt noch die Möglichkeit, mittels "Durchstreichen" einen Gegenstand zu löschen oder Kettenglieder zu zerteilen. Das Video oben zeigt schon sehr viele der Bedienmöglichkeiten, so dass eine aufwändige Einarbeitung entfällt.<br />
Weitere Unterstützung liefert die Website, wo es neben einem FAQ und einem Tutorial auch ein gut besuchtes Forum gibt, wo sich auch über den Einsatz von Phun zu Bildungszwecken unterhalten kann. Ebenso stellen dort User ihre selbst erstellten Szenarien ein und diskutieren über diese. Ein Ausbau dieses Angebot mit Hinwendung zum schulischen Bereich wäre denkbar. Vielleicht kann man sich irgendwann einmal bei von Plattformen wie <a href="http://4teachers.de/" target="_self">4teachers.de</a> nicht mehr nur Arbeitsblätter und Unterrichtsentwürfe herunterladen, sondern auch Phun-Anleitungen und -Szenarien.</p>
<p>Wie gezeigt bietet die Software eine Menge Möglichkeiten. Was haltet ihr davon? Welche Vorteile bietet Phun, wo sind Schwierigkeiten beim Einsatz im Unterricht zu sehen? Welche Unterrichtsszenarien mit Phun sind neben den oben genannten noch denkbar? Ich freue mich schon sehr auf Ideen und Diskussionen!</p>

<p><a href="http://phun.cs.umu.se/wiki" target="_blank">Phun</a> is out for OSX! Okay, it came out a few weeks ago, but I just got around to downloading it. Phun is a 2-D Physics sandbox.<br />
<span style='text-align:center; display: block;'><object width='425' height='350'><param name='movie' value='http://www.youtube.com/v/0H5g9VS0ENM'></param><param name='wmode' value='transparent'></param><embed src='http://www.youtube.com/v/0H5g9VS0ENM&rel=0' type='application/x-shockwave-flash' wmode='transparent' width='425' height='350'></embed></object></span></p>
<p>At this time, I have no idea how I'll use this in class, but I have a new prep to plan for next year and a summer that is mostly unplanned.</p>
<p><span style="font-size:large;"><strong>3D</strong></span></p>
<p>Via <a href="http://infosthetics.com/archives/2008/05/tag_galaxy.html" target="_blank">information aesthetics</a> I ran across <a href="http://taggalaxy.de/" target="_blank">Tag Galaxy</a>, a 3-D<span style="font-size:xx-small;"><sup>1</sup></span> representation of photos on <a href="http://flickr.com/" target="_blank">flickr</a> by tag. Each planet represents photos of related tags. Of course I had to see what the math tag looked like:</p>
<p style="text-align:center;"><img class="aligncenter" style="vertical-align:middle;" src="http://www.jackieb.brokenruler.com/Web/Math_Tag_Orbit.png" alt="" width="665" height="351" /></p>
<p style="text-align:left;">I had planned to post the screen shot of the "planet" of photos. However, the first photo I checked was <strong>not</strong> licensed under a Creative Commons License. So, be careful.<span style="font-size:xx-small;"><sup>2</sup></span></p>
<p><span style="font-size:large;"><strong>4D</strong></span></p>
<p style="text-align:left;">I've got nothing, sorry. Although I do keep bugging a friend to work on a time machine. Alas, he hasn't come through yet.<span style="font-size:xx-small;"><sup>3</sup></span></p>
<p><span style="font-size:xx-small;"><sup>1</sup>Obviously it is really two dimensional. Also, I think it is more of a planetary system than a galaxy.<br />
<sup>2</sup>In a strange coincidence, the first photo I checked for CC belonged to <a href="http://www.virtualcourtney.com/" target="_blank">Courtney</a>.<br />
<sup>3</sup>I know, I know. He hasn't built a tesseract either.</span></p>
