Comment: Not worry about after crash, but AVOID CRASH (Score 1) 756

I spend most of my time driving NOT crashing. I'd worry less about where my hands are after a crash and more on where to place my hands to give me the best control of the vehicle so as to AVOID crashing. That might easily be tested in simulators. If I were a betting man, I'd place money more on 10-2 than 6:30-5:30.

Professional writers spend a lot of time doing research. Lots of research. This means reading material about the subject matter. Use Google and see what's online, but also read a few dozen books from a good library. That being said, you don't need a lot of technical detail; you're going to write a story. That involves realistic characters, dialog, and relationships. This is what will make you succeed (or fail) as a writer.

Studies in this field are really difficult to do. A rigorously defensible experimental regime is nearly impossible to establish. Inferences made from Factor Analysis and Correlation matrices are nearly shaky as Ouija boards and Yarrow sticks. Low numbers of casual observations made from a preselected class of people does not constitute good random sampling. The best conclusions in the field would barely serve as hypotheses in a true science. The "softer" sciences are extremely difficult to work with.

NASA To Demonstrate Largest-Ever Solar Sail in Space 91

Zothecula writes "NASA's upcoming Technology Demonstration Missions are intended to 'transform its space communications, deep space navigation and in-space propulsion capabilities.' Three project proposals have been selected for these missions, which should be launching in 2015 and 2016. One of those projects will involve demonstrating a mission-capable solar sail. While NASA has recently tested a solar sail measuring 100 square feet (9.29 square meters), this one will be the largest ever flown, spanning a whopping 409 square feet, or 38 square meters."

Do not underestimate the value of print statements for debugging.
