Hi Luis,

" if you're reading this, did you go out and get a new brain this summer? "

I didn't get a new brain, but I did spend a fair amount of time studying Einstein. That's the kind of thing nerds do with their free time, don't you know? :-)

" The "Aurino Souza" I remember didn't understand Einstein "

You're quite right about that, but I don't feel too bad about it as I'm far from being alone. The world is full of people with PhDs in physics who don't understand Einstein either. But it sure feels good to "out-PhD" some PhDs :-) :-) :-)

All in all, I think we shouldn't get too hung up on each other's mistakes, after all this world is too damn complicated for any single person to understand. When even a genius like Einstein can say stupid things* what hope is there for the rest of us?

Regards,

Aurino
