<p>Excellent introduction to human believing mechanisms. Michael Shermer covers pretty much everything from the foundations of moral values to religious and political preferences. Several perspectives (Evolution, neuroscience, socio/anthropology, etc). Cognitive biases and belief-induced historical and scientific misunderstandings&#8230;</p>
<p>Actually quite good.</p>

			<content:encoded><![CDATA[<p>Just heard this fantastic mnemonic memory trick by Brian Dunning (host of the <a title="The Skeptoid Podcast" href="http://skeptoid.com/" target="_blank" onclick="urchinTracker('/outgoing/skeptoid.com/?referer=');">Skeptoid Podcast</a>) in <a title="Follow Dr Karl (and the naked Scientists for the same price) on BBC 5 Live's Podcast" href="http://www.bbc.co.uk/podcasts/series/drkarl" target="_blank" onclick="urchinTracker('/outgoing/www.bbc.co.uk/podcasts/series/drkarl?referer=');">Dr. Karl&#8217;s (BBC) Podcast</a>.</p>
<p><strong>How do you know if you&#8217;re talking about a trillion? Quadrillion? Quintillion? Sextillion?</strong></p>
<p>Turns out it&#8217;s actually quite easy:</p>
<ul>
<li>Count the number of zeros</li>
<li>Remove 3</li>
<li>Divide by 3 and interpret the result
<ul>
<li>1 zero left (mono) =&gt; million</li>
<li>2 (bi) =&gt; billion</li>
<li>3 =&gt; trillion</li>
<li>4 =&gt; quadrillion</li>
<li>5 =&gt; quintillion</li>
<li>6 =&gt; sextillion</li>
<li>7 =&gt; septillion</li>
<li>8 =&gt; octillion</li>
<li>9 =&gt; nonillion</li>
<li>10 =&gt; decillion</li>
<li>11 =&gt; undecillion</li>
</ul>
</li>
</ul>
<p>Amazing isn&#8217;t it? It works for languages &amp; countries that use the &#8220;Short Scale&#8221; (that is, English speaking countries and Brazil according to <a title="Long and short scales on Wikipedia" href="http://en.wikipedia.org/wiki/Long_and_short_scales" target="_blank" onclick="urchinTracker('/outgoing/en.wikipedia.org/wiki/Long_and_short_scales?referer=');">Wikipedia</a>). A pity the rest of the World uses the French &#8220;Long Scale&#8221;, which has nothing logical to it <img src='http://alan.vonlanthen.org/wp-includes/images/smilies/icon_sad.gif' alt=':(' class='wp-smiley' /> </p>

			<content:encoded><![CDATA[<p>La vulgarisation scientifique est un de mes vieux rêves et il est en train de se concrétiser, avec les moyens du bord, mais il se concrétise quand même!</p>
<p>En effet, <a title="le site de Mathieu" href="http://www.mfavez.com" target="_blank" onclick="urchinTracker('/outgoing/www.mfavez.com?referer=');">Mathieu Favez</a> et moi-même venons de boucler le premier numéro de <a title="podcastscience.fm" href="http://www.podcastscience.fm" target="_blank" onclick="urchinTracker('/outgoing/www.podcastscience.fm?referer=');">Podcast Science</a>, la science sans prise de tête.</p>
<p>Il s&#8217;agit d&#8217;un rendez-vous hebdomadaire, à ne manquer sous aucun prétexte, qui décortique pour vous l&#8217;actualité scientifique avec des mots de tous les jours, et propose un dossier sur un grand thème de la science. Le tout intercalé de discussions entre deux passionnés qui cherchent à communiquer leur passion tout en passant un bon moment.</p>
<p>Des sujets un peu ardus au menu de cette première semaine:<br />
- Un problème mathématique à un million de dollars<br />
- La preuve scientifique est-elle scientifiquement prouvée?<br />
- Une petite vidéo d&#8217;un vulgarisateur scientifique qui a de la bouteille<br />
- Et la minute philosophique de la semaine avec François Rabelais</p>
<p>Comment écouter le podcast?</p>
<p>Soit en ligne, à l&#8217;adresse suivante: <a href="http://www.podcastscience.fm/" target="_blank" onclick="urchinTracker('/outgoing/www.podcastscience.fm/?referer=');">http://www.podcastscience.fm/</a></p>

			<content:encoded><![CDATA[<p>Pas encore écouté, un peu peur d&#8217;ailleurs, ça devait bafouiller ferme&#8230; Autant je me sentais relax avant que l&#8217;émission ne démarre, autant le live m&#8217;a stressé. Et quand je stresse, ce qui est malheureusement le cas la plupart du temps, je n&#8217;ai plus accès qu&#8217;à un dixième de mes facultés cognitives (mémoire, vocabulaire, &#8230;) Faut que je me mette au yoga&#8230;</p>
<p>Mais bon, malgré tout, c&#8217;était super cool à faire, je me suis régalé!</p>
<p>Je me suis juste livré à une petite revue de presse des sujets  scientifiques lus ces 15 derniers jours et qui concernent la tech (le thème de mon podcast préféré)</p>
<p>Juste un regret: j&#8217;ai complètement oublié de parler de mon coup de coeur, un excellent blog de vulgarisation scientifique en français (si si!), <a href="http://lorelinerobbe.canalblog.com/" target="_blank" onclick="urchinTracker('/outgoing/lorelinerobbe.canalblog.com/?referer=');">http://lorelinerobbe.canalblog.com/</a></p>
<p>La prochaine fois, j&#8217;y pense, promis!</p>
<p>Un tout grand merci encore à <a title="@bcurdy" href="http://twitter.com/bcurdy" target="_blank" onclick="urchinTracker('/outgoing/twitter.com/bcurdy?referer=');">@bcurdy</a> et <a title="@Syde" href="http://twitter.com/syde" target="_blank" onclick="urchinTracker('/outgoing/twitter.com/syde?referer=');">@syde</a> de l&#8217;invitation.</p>

<p>In other words, we&#8217;re not fond of honey because it&#8217;s sweet, but it tastes sweet because our brain loves it. We don&#8217;t love our babies because they&#8217;re cute, but we find them cute because the contrary would have led us to extinction. Same reasonning for what we feel is sexy. And the best is undoubtedly about humour, which merely reflects how our brain is wired: what a satisfaction it is to us when we eventually understand the underlying mecanisms behind anything.Â  Laughing is our little treat. All this is called the &#8220;Hurley model&#8221; and will be described in a book to come by Matthew Hurley, Reginald Adams Jr and Dan Dennet.</p>
