Just read your review of Sebag's 'Enigma'.

You are right about the technical gobbledy-gook. I don't think he understands the technical stuff at all.

On the Herivel Tip, for example, he says "...all they had to do was plot a point on a graph...". The nature of this graph is undisclosed. He refers in fact to the 'Herivel Square', explained in Herivel's Wikipedia article. Many other examples...

So do not doubt your own technical competence.....

Thanks for sharing such a useful information, I thing depression is a part of out life; but if its overloaded then its bad can damage our mind. I may be wrong but i thing some time its not possible not to be depressed.
