Throughout history we’ve seen examples of artists and others who, while possessing amazing talent, also don’t seem “normal.” Whether it be tormented artists like Vincent van Gogh, or the stereotype of the “mad scientist,” it often seems like a little schizophrenia might underlie amazing genius.
In fact, some psychological studies have found that schizophrenics do tend [...]... Read more »

It was one of the most memorable scenes in Jurassic Park—a hungry Tyrannosaurus rex chasing after Ian Malcolm, Ellie Sattler and Robert Muldoon as they make their escape in a Jeep. It was also among the moments that probably made paleontologists in the audience facepalm. Tyrannosaurus was fearsome, but it was way too big to [...]... Read more »

Is there an underlying structure common to all languages? There are at least two arguments in favor of that position. One is an in principle argument, and one is based on observed data.
Since Chomsky, many researchers have noted that language would be impossible to learn if one approached it without preconceptions. It's like solving for 4 variables with only 3 equations -- for those of you who have forgotten your math, that can't be done. Quine pointed out the problem for semantics, but the pro........

Many non-scientists misunderstand the basic way science works. While there are indeed huge discoveries that fundamentally change the way we think about things, the vast majority of the time published papers are a steady plod onwards, adding in very modest amounts to the staggering array of human knowledge. Often seismic shifts in scientific opinion don’t come from great discoveries but from many scientists reading the literature and arguing among themselves and coming to different conclusions ........
