Wind Map An invisible, ancient source of energy surrounds us—energy that powered the first explorations of the world, and that may be a key to the future. This map shows you the delicate tracery of wind flowing over the US. The wind map is a personal art project, not associated with any company. We've done our best to make this as accurate as possible, but can't make any guarantees about the correctness of the data or our software. If the map is missing or seems slow, we recommend the latest Chrome browser. Surface wind data comes from the National Digital Forecast Database. If you're looking for a weather map, or just want more detail on the weather today, see these more traditional maps of temperature and wind.

But are such rockets possible? How does one go about defining the performance of these atomic-powered cruisers? This document gives some hints and equations that will allow back-of-the-envelope calculations on such matters. Though horribly simplistic, they are far better than just making up your figures. This site was mainly intended for science fiction authors who wanted a little scientific accuracy so they can write SF "the way God and Heinlein intended" (Arlan Andrews's Law). The engine and the torchship pages explain how easily do some of the calculations using Nomograms. . While this site originally focused on rocketry equations, as you can see it has grown to encompass other topics of interest to SF authors and game designers.

At least. The total number comes in at about 2 trillion of them. Now, let me be clear. This doesn’t meant the Universe is 10 times bigger than we thought, or there are 10 times as many stars. What the astronomers did was look at extremely deep images of the Universe taken in surveys, for example the Hubble Ultra Deep Field. That’s a lot of galaxies. Surveys like the UDF are limited. The astronomers who did this research had an interesting problem. The answer is two-fold. Those numbers change with distance. At the same time, these faint galaxies are easier to see close to us, and harder farther away. They calculated this for all kinds of galaxies, right down to really small ones with about a million times the mass of the Sun. And that’s how they found that there are at least 2 trillion galaxies in the Universe.
