I have been thinking about writing some short scifi stories and thought it would be good to have a place to exchange formula's and facts that would be good to know.<br /><br />For instance the formula for rotational speed as it relates to simulated gravity<br /> F=(.0011)W^2*R <br /><br />F is cetrfugal force in gravities<br />W is rpm<br />R is radius in meters<br /><br /> If anyone knows of any good links for this kinda stuff it would be cool to share them.
