 <title>maybe the theory is not crazy after all .... if only:</title>

 <description>&lt;p&gt;
If only we consider that the basic mechanism for bubble formation is compression of thin layers, which clearly in rubber and with no asperity makes the slow Schallamach &amp;quot;waves&amp;quot; (or better, fronts) that we have been able to see already with technology of the 1960&amp;#39;s. But there is no reason &lt;em&gt;not&lt;/em&gt; to admit bubbles can also be generated within asperities of micron scale, at nanometer scale, so that we cannot see them.... Yet!&amp;nbsp; But together, we see their movement. I wish de Gennes were alive, I was supposed to meet him last year in Trieste at a workshop, I cannot tell you how disappointed I was not to have had the chance to meet with him. Now, I could have stepped into his office in Paris and he would have confirmed or disprooved my theory in less than a second.
&lt;/p&gt;
&lt;p&gt;
So this seems to be one case where, as Michel de Montaigne says, &amp;quot;I only took other people&amp;#39;s flowers, and all I did was to find the chord to bind them&amp;quot;!&amp;nbsp; So here the idea may not be that crazy, just the natural step forward on the shoulders of giants like Bowden, Tabor, Johnson and ... especially de Gennes!
&lt;/p&gt;
