[edit] Format

The page has a table at the moment and some of the numbers on the left don't coincide with the facts on the right. Could we just make this a list of sorts with things like:

  • 1m/s typical human walking speed; speed of action potentials in brain
  • 586,000 miles/sec ~speed of light

Seems like something in this format might fix the alignment problems, though, on looking at the preview it still isn't quite right; I think the text is too close to the numbers. The original table could of course be fixed itself but I don't know how. Snowmanmelting 02:30, 17 August 2005 (UTC)

[edit] Energy and Power

I was looking over here, and it says that accelerating a 3000 ton object to 120,000 kilometers a second will have the force of around 1E22 joules, a rather high number. I don't quite get how they got this number. Anyone care to explain? The Gwai Lo 02:11, 5 December 2005 (UTC)

It appears to have been calculated using the formula for kenetic energy: E_{\rm k} = \frac{1}{2}mv^2. Note that joules measure energy, not force. Indefatigable 20:44, 24 January 2006 (UTC)
the MAC cannon article is about a pure sci-fi thing though this isn't clearly mentioned and the references etc. rather make it look like a page describing a real thing. I think this should be fixed. anyway, on earth nobody could even accelerate a gun bullet to that speed, which is over 1/3 of the speed of light, so the classical mv²/2 formula isn't good anymore, either, and relativistic formula should be used instead. — MFH:Talk 22:47, 20 October 2006 (UTC)

[edit] benz unit

are there references for the "benz unit" ? never heard of that. — MFH:Talk 22:39, 20 October 2006 (UTC)
