We Didn’t Evolve to Do Physics, Which Is Why It Seems So Weird

Physicist Lawrence Krauss explains why understanding new theories in physics is so hard, and why it’s so much fun.

Physicist Lawrence Krauss says there’s a perfectly good reason so many theories in physics are hard to wrap our minds around: Our brains didn’t evolve for such heavy lifting.


Natural selection didn’t favor homo sapiens for our ability to ponder spooky action at a distance, he notes. It favored us because we learned how to get away from those big hungry predators. So relativity’s a bit of a stretch for us refugees from the savannah.

But that’s okay, says Krauss. In fact, it’s what makes science and physics so much fun.

So don’t feel bad if understanding something new means just sitting and thinking about it for a little bit, and don’t feel bad you — we — don’t know more. Doing a puzzle’s much more enjoyable than having done one.

Plus also, there are no predators chasing us.

Why I wear my life on my skin

For Damien Echols, tattoos are part of his existential armor.

Videos
  • In prison Damien Echols was known by his number SK931, not his name, and had his hair sheared off. Stripped of his identity, the only thing he had left was his skin.
  • This is why he began tattooing things that are meaningful to him — to carry a "suit of armor" made up the images of the people and objects that have significance to him, from his friends to talismans.
  • Echols believes that all places are imbued with divinity: "If you interact with New York City as if there's an intelligence behind... then it will behave towards you the same way."
