I'm still in a holiday mood so forgive one more prank before moving to serious physics (as if this blog were ever serious ;-). Traveling to conferences this summer I noticed that humans had acquired a new useful skill. Have a look at this picture:
and there are many more similar ones stored on my disc ;-) Of course, the interesting point here is not sleeping during a talk - everybody does that. The remarkable point is perfect balancing of a laptop while sleeping. In the extreme case it went on for 45 min without awaking and without dropping the laptop to the floor. Amazing!
Using Darwin's theory of evolution one can predict that this new skill will quickly spread in the scientific community.Those who do not possess it will inevitably destroy their laptops while sleeping at conferences, thus losing years of work and dropping in the academic ranking. As a consequence, these handicapped ones will acquire less mating partners and thus less chances to pass their genes. Unless laptops become shock resistant in the meantime.
