Near Lurker:
...I know the concept of "irrational integers" is a reference to something (fictional), but I can't think what.

Scale is important. B5 is supposed to be 5 miles long. So it is also, nearly 400m radius (1/2 mile diameter). The angular velocity to create 1g on the outermost rings of B5 is not visually all that fast.

So Babylon 5 lied to me?

I don't know. What happens there?

I had to view the clip a couple of times to see it on my dirty laptop display, but yeah... Here the size of the station matters. If the radius of the station is 1km, then 1RPM gives about 1 g of gravity. But for a bigger station a slower rotation suffices. If the radius is 4km, then ½ RPM gives 1 g. If the radius is 16 km or 10 miles, then one quarter of a turn per minute will do. Akima's spreadsheet will give you more significant figures.  :wink:

Edit: Ninja'ed by jmucchiello. But if B5 has a radius of only 400 m, then we need something like 1.6 RPM to get 1 g.

Don't know about fictional, but most (in a certain sense) of the so called algebraic integers are irrational. </math_teacher>

Carl-E:
Most birthdays are irrational, too! 

And Skewbrow, Most numbers  are irrational, but not any  integers. 


Edit:  Missed the algebraic part.  you are, of course, correct.  :D

Now it makes sense once I re-saw the Severed Dreams Battle.
