  1. Gravity = Isaac Gravitation = Albert

  2. that's funny because so much aerospace has happened, and still happens, near Ventura Blvd.

  3.  @Krasnoo  than why are they dying to get here? You can't even own five AR15s, let alone one, nor can you say whatever you want, w/o going to jail. Sux 2b u.

  4. It's microgravity because the ISS decelerates b/c of air resistance at roughly 0.0001 m/s^2, or, if you prefer useful units: 2 mph/day.

  5. Does QCD really care about flavor?

  6. 1/2 mv^2. Unless v << c is not true. Then use: [1/sqrt(1-(v/c)^2) -1]*mc^2

  7.  @scottmanley  My numbers agree. U235 averages 200 MeV per fission. 1000g/235 g/mol = 4.2 moles. Times 6e23, times 1.6e-19 J/eV , divided by 4.6 GJ/ton_TNT = 19.6 kT = 20kT. Bam. Most of that energy is nuclear binding energy...which is mass, so your original statement is correct. There are a few beta+ emitters in nuclear waste, so a tiny amount comes out as 511 keV gamma rays, aka: antimatter annihilation.

  8. but the local gravitational field in the ISS has a mean of 1 micro-g b/c of air resistance, while the tidal gradient is around 300 ng/m (micro over 3 meters). Micro gravity is the perfect name.

  9.  @SergKiev87  at the center, you are falling forward at 2 mph/day b/c the local gravitational field. If you're swole, you might feel a torque coupling your mass quadruple moment to the tidal gradient, if you are body positive (no multipole moments), not so much.

  10. but they are correlated. There is a dead-time after a stroke. On the other hand, just plot their time series and look at the autocorrelation.
