"In 1926 German physicist Werner Heisenberg determined that it ws impossible to measure the trajectory of an electron hurtling through space. Light waves were too big to cast a shadow of the tiny particle, and gamma rays--which have a much smaller wavelength--were too powerful. As soon as gamma rays struck the electron, they knocked it off its course. The very act of observing the electron thus altered its behavior and contaminated the experiment.
"Extrapolating from this phenomenon, Heisenberg formulated his famous Uncertainty Principle, which states that there are some things, such as the speed and trajectory of an electron, that we can never know for certain because the very act of observing them changes the data."

How do we truly know anything?
