			<content:encoded><![CDATA[<p>A couple of must-see movies which also sport a must-have soundtrack:</p>

<ul>
    <li>Juno</li>
    <li>Once</li>
    <li>Almost Famous</li>
    <li>Harold and Maude</li>
    <li>Magnolia</li>
</ul>

<p>Those are just a few that come to mind. After recently watching Juno and Once, I was reminded of how potent a mixture film and music can be. More than just being a backdrop to what happens on screen, these soundtracks form the soul of the stories. (Interesting thought: While the soundtracks can each be enjoyed on their own, I suspect a movie from the above list stripped of its music would have a rather bleak and dead feeling about it&#8230;)</p>

This is great news. Growing up on the Mac side of the first-person shooter saga, I&#8217;ve immensely enjoyed Bungie&#8217;s Marathon Trilogy, but missed out on everything id. Yes, Wolfenstein 3D, Doom and the rest were available on the Mac (probably with the usual delay, [...]]]></description>
			<content:encoded><![CDATA[<p>Last week, Valve <a href="http://www.steampowered.com/v/index.php?area=news&amp;id=1141">announced</a> the immediate availability of <a href="http://www.steamgames.com/v/index.php?publisher=id"><strong>id</strong> games on Steam</a>.</p>

<p>This is great news. Growing up on the Mac side of the first-person shooter saga, I&#8217;ve immensely enjoyed Bungie&#8217;s <a href="http://en.wikipedia.org/wiki/Marathon_Trilogy">Marathon Trilogy</a>, but missed out on everything <strong>id</strong>. Yes, Wolfenstein 3D, Doom and the rest were available on the Mac (probably with the usual delay, but I could be wrong, since this is <strong>id</strong>), but Mac gamers scoffed at Doom&#8217;s lack of any serious plot. &#8220;But Doom is fun!&#8221; Yes, yes. We wanted our first-person carnage to be high-brow. It was all about getting to the next terminal to delve further into the story. The shooting on the way there was necessary, but we didn&#8217;t enjoy it too much. No, really.</p>

<p>Anyway, the time has finally come to check out what I have missed. Look at <a href="http://www.steamgames.com/v/index.php?area=package&amp;SubId=440">this package</a>, for the insane price of $62.95 ($69.95 after August 10):</p>

<ul>
<li>Commander Keen, Episodes 1 through 5</li>
<li>Wolfenstein 3D</li>
<li>Spear of Destiny</li>
<li>Return to Castle Wolfenstein</li>
<li>Ultimate DOOM</li>
<li>DOOM II</li>
<li>Final DOOM</li>
<li>DOOM3</li>
<li>DOOM3: Resurrection of Evil</li>
<li>QUAKE</li>
<li>QUAKE Mission Pack 1: Scourge of Armagon</li>
<li>QUAKE Mission Pack 2: Dissolution of Eternity</li>
<li>QUAKE II</li>
<li>QUAKE II Mission Pack: The Reckoning</li>
<li>QUAKE II Mission Pack: Ground Zero</li>
<li>QUAKE III Arena</li>
<li>QUAKE III: Team Arena</li>
<li>Heretic</li>
<li>Heretic: Shadow of the Serpent Riders</li>
<li>HeXen</li>
<li>HeXen: Deathkings of the Dark Citadel</li>
<li>HeXen II</li>
</ul>

<p>Another nifty aspect of this style of distribution is that you can play oldies like Commander Keen without worrying about compatibility with modern operating systems like Windows XP. The game comes packaged with <a href="http://dosbox.sourceforge.net/">DOSBox</a>, but you won&#8217;t even notice the setup work behind the scenes if you don&#8217;t pay close attention when the game is starting. You just install it and play. This is something about online delivery that&#8217;s very promising: Making old games easily and cheaply available for modern systems. (The recent release of <a href="http://www.xbox.com/en-US/games/m/marathondurandalxboxlivearcade/">Marathon 2: Durandal on Xbox Live Arcade</a> comes to mind.)</p>

<p>My plan is to play through these games, one at a time, in chronological order. That means I am starting with this:</p>

<p><img src="http://www.mcduke.net/blog/wp-content/uploads/2007/08/ckeen.png" alt="Commander Keen" /></p>

<p>And will, in a couple of years (and after I&#8217;ve upgraded my hardware), finish with this:</p>

<p><img src="http://www.mcduke.net/blog/wp-content/uploads/2007/08/doom3.jpg" alt="Doom 3" /></p>

<p>Gory times ahead! But first for some pogo stick jumping&#8230;</p>

			<content:encoded><![CDATA[<p><a href="http://users.bigpond.net.au/d.keenan/ChildrenAndReligiousBeliefs.htm">This</a> echoes much of what I believe to be the best way to educating one&#8217;s children about Life, the Universe and Everything. From the section <em>What I do intend to indoctrinate my children with as early as possible</em>:</p>

<blockquote>
  <p><strong>Wisdom</strong></p>
  
  <ul>
  <li>Doubt the stories people tell about how the world is, (especially about God, creation, birth, death, etc.) for as long as possible. But learn all the ways in which we fool ourselves, and search diligently for your own answers. </li>
  </ul>
  
  <p><strong>Compassion</strong></p>
  
  <ul>
  <li>The two most important things to do while you are alive, are to be kind and to be happy. That is, to be kind to all creatures including yourself.</li>

			<content:encoded><![CDATA[<p>I just stumbled across the very interesting <a href="http://www.templeton.org/spirituality_and_health/step.asp">STEP study</a>:</p>

<blockquote>Intercessory prayer is widely believed to influence recovery from illness, but
claims of benefits are not supported by well-controlled clinical trials. Prior studies have not
addressed whether prayer itself or knowledge/certainty that prayer is being provided may
influence outcome. We evaluated whether (1) receiving intercessory prayer or (2) being certain
of receiving intercessory prayer was associated with uncomplicated recovery after coronary
artery bypass graft (CABG) surgery.</blockquote>

<p>The results reveal what should be obvious anyway: Intercessory prayer doesn&#8217;t work. One amusing aspect of the study results is that the test group that had been told it was going to be prayed for showed significantly more complications in the 30-day period following the operation (58.6%) compared to the other groups (52.2 and 50.9). That is probably just a chance statistical burst, but maybe also due to some psychological effect. This is totally unfounded speculation on my part, though.</p>

<p>On a related note, Daniel C. Dennett, author of <em>Darwin&#8217;s Dangerous Idea</em> and <em>Breaking The Spell: Religion as a Natural Phenomenon</em>, recently had to undergo surgery due to a dissection of his aorta, but seems to be recovering well. <a href="http://www.edge.org/3rd_culture/dennett06/dennett06_index.html">Thank Goodness</a>, and please don&#8217;t pray for him!</p>

			<content:encoded><![CDATA[<p>&#8230;is that they don&#8217;t take themselves too seriously, but focus on getting the essence of the subject across in a simple, straight-forward, maybe at times even humorous manner.</p>

<p>That&#8217;s how <a href="http://www.amazon.de/exec/obidos/ASIN/0333772431/mymind-21/">Calculus Made Easy</a> by Silvanus P. Thompson (in an updated edition with some additional preliminary chapters and footnotes by Martin Gardner) stands out among the rows of thick volumes of calculus, heavy with their own importance, filled with everything you might possible ever, and will probably never, need. And in the most formal, complicated way of expressing things, too, of course. Thompson seems to have strived to comply with Einstein&#8217;s famous advice to make things as simple as possible, but no simpler.</p>

<p>Very heartening is the subtitle to this 300-somewhat pages thin book: (And yes, that <em>is</em> thin, especially when you compare it to the above-mentioned tomes.)</p>

<blockquote>Being a very-simplest introduction to those<br />
beautiful methods of reckoning which<br />
are generally called by the<br />
terryfing names<br />
of the<br />
DIFFERENTIAL CALCULUS<br />
and the<br />
INTEGRAL CALCULUS</blockquote>

<p>Or the &#8220;ancient Simian proverb&#8221; at the beginning:</p>

<blockquote>What one fool can do, another can.</blockquote>

<p>By the way, this is by no means a new book: It was first published in 1910, and has never been out of print since. So if you&#8217;re looking for a good introduction to calculus that has stood the test of time &#8212; look no further.</p>
