In this long video, Yves Meyer addresses the question of his vocation for the beauty and truth of mathematics from the moment 9 minutes 41 seconds. I&#8217;m going back to my childhood.

Now there has been some debates about it as you can listen on NPR. It is a marxist analysis.

					<description><![CDATA[A revealing debate on &#8220;Why haven&#8217;t we created a Google yet?&#8221; [in France]. It&#8217;s fascinating, irritating when you disagree, and exhilarating when you recognize yourself in the discussion. Needless to say where I stand&#8230; but I should add that my reading of the book *Palo Alto*, which I&#8217;ll be discussing here soon, compels me to [&#8230;]]]></description>
