The depressing thing about battery technology is that it gets better, but it gets better slowly. There are a whole bunch of problems in materials science and chemistry that come in trying to make existing batteries better.
Nathan MyhrvoldWhen I was about nine years old, I announced to my mother that I was going to cook Thanksgiving dinner. And I went to the library and got this whole pile of books. I'd love to say it all turned out great. It didn't. But, sort of, from that point on, whenever there was serious cooking at home, I was the one who did it.
Nathan MyhrvoldMost estimates of the mortality risk posed by asteroid impacts put it at about the same risk as flying in a commercial airliner. However, you have to remember that this is like the entire human race riding the plane - it is one of the few risks that really could wipe us all out.
Nathan MyhrvoldRisk is the sort of word that is easy to discuss upfront but tough to handle when it comes time to pay the piper. There will always be some who wimp out and second-guess when the pain hits, but that is a childish reaction.
Nathan MyhrvoldIf you have two steaks, one that's an inch thick, one that's 2 inches thick, how much longer does the thicker one need to cook? It's four times as long. It goes roughly like the square. How come cookbooks don't tell you that?
Nathan MyhrvoldFood, like anything else, lives in the physical world and obeys the laws of physics. When you whisk together some oil and a little bit of lemon juice - or, in other words, make mayonnaise - you are using the principles of physics and chemistry. Understanding how those principles affect cooking lets you cook better.
