One of the problems with posing a 'bold new plan' is that you can't just extrapolate from previous plans.

What you do on a dinosaur expedition is you hike and look at the ground. You find bones sticking out of the dirt and, once you see something, you dig.

Our reactor actually burns nuclear waste as fuel. So not only is it safe and powerful, it solves an important issue: It actually reduces nuclear waste instead of creating. It's the reactor of your dreams.

Most visions of extraterrestrial life are actually steeped in human hubris. The fictional extraterrestrials of 'Star Trek' or a hundred other space operas are less alien than many of my neighbors. And funny, the ones running the place are mostly WASPish men.

Chefs think about what it's like to make food. Being a scientist in the kitchen is about asking why something works, and how it works.

Cooking is for chefs. Science informs us and lets us cook while knowing what we are doing, but it is not a replacement for the skills of a chef.

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.
