The processing capacity of the conscious mind has been estimated at 120 bits per second.

I have never seen a proton or electron spinning around it. I have never actually seen a chromosome. I trust that they exist because people who I trust tell me they do.

A song playing comprises a very specific and vivid set of memory cues. Because the multiple-trace memory models assume that context is encoded along with memory traces, the music that you have listened to at various times of your life is cross-coded with the events of those times. That is, the music is linked to events of the time, and those events are linked to the music.

Ten thousand hours is equivalent to roughly three hours a day, or 20 hours a week, of practice over 10 years... No one has yet found a case in which true world-class expertise was accomplished in less time. It seems that it takes the brain this long to assimilate all that it needs to know to achieve true mastery.

It's getting harder and harder to know, when you find things on the Internet, what you can believe and what you can't.

Most of what we know we don't really know first hand. I've never seen a cancer cell. But I trust this community of experts who have, so I believe that cancer exists. But we trust these experts, and we trust that the experts have a system of checks and balances and self-correction. And we have to insist that experts have certain certifications. They're not perfect. Every once in awhile there's an engine falls off the wing of a plane, or a tax audit happens and you find out your expert made a mistake. But it's a pretty good system. It's the best system we've got.

We need to take a step back, and realize that not everything we encounter is true. You don't want to be gullibly accepting everything as true, but you don't want to be cynically rejecting everything as false. You want to take your time to evaluate the information.
