It's very hard for individual inventors to get paid. For the same reason that private equity is valuable - broadly, that's a good thing - in the case of patents, many that own them aren't in a good position to take the next step.

I was good at math and science, and I got lots of degrees in lots of things, but in a parallel universe, I probably became a chef.

Most 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.

Wine lovers have known for centuries that decanting wine before serving it often improves its flavor. Whatever the dominant process, the traditional decanter is a rather pathetic tool to accomplish it. A few years ago, I found I could get much better results by using an ordinary kitchen blender.

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.

Risk 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.

Food, 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.
