as in physics, so in life.

i noticed that when people talk about smart scientists, they normally mention Einstein. he sure was a clever cookie. but so was Werner Heisenburg. he's most famous for his Uncertainty Principle. he found that the outcome of any experiment will always be influenced by the presence of an observer, no matter how impartial or uninvolved that witness tries to be.

we definitely do influence things and people just by looking at them.. :)
