We've peered back in time to the early days of the universe, just following the Big Bang, and unraveled the mysteries of the human genome -- yet we don't really know how a moving bicycle manages to stay upright without a meatbag manning the handlebars. Scientists have long thought that it had something to do with the gyroscopic effect created by the spinning wheels and the caster effect of having the front wheel trail the steering axis (don't worry, it's all explained in a video at the source link). Researchers at Cornell, however, have created a tiny bike that generates neither of those effects yet, thanks to carefully calibrated mass distribution, still st
