:::: You are out by a factor of 1000. A kiloton of TNT-equiv is approximately 4.185*10e12 Joules. The kiloton equivalent for the figure GregG gave would be about (given he didn't use the approapriate figure for the speed of light in a vacuum I'll approximate as well) 20000 kilotons (20 megatons).

:::::Correct. I was doing the conversion in my head. It's should be something around 21,500 kilotons (21.5 megatons). Which of course would make my subsequent conversion incorrect as well. I guess that would make me.... wait for it... wrong. Thanks for the correction DVergne. Wow! It's surprisingly easy to admit you're wrong! Maybe other people will try it... --[[User:DonnyC|DonnyC]] 02:04, 18 January 2013 (EST)

::::::Indeed, 1kg has an equivalent energy of <math>9 \times 10^{16}J</math> - a immense number: it equals 25TWh - the output of all German power-stations combined in a fortnight. On the other hand, the sun emits <math>3.8 \times 10^{26}W</math> this means that it loses roughly 15 Trillion kg each second - or the mass of our Moon in less than 57 days.
::::::But we have had other examples of the equation on this talk-page:
::::::*In Cockroft's experiment, a mass of <math>3.0616 \times 10^{-29}kg </math> is transformed into an energy of <math>2,755 \times 10^{-12}J</math>
::::::*In Compton's experiment, rays having a frequency of a couple of EHz are used. The photons have an energy W=h*f, and interact with electrons as having a mass of W/c².
::::::This is about measurement, not politics. And please, Andrew, answer [[#A few questions for Aschlafly regarding the experiment of Cockcroft¹ and Walton]]: those questions may be difficult for a lawyer, but nor for an engineer. So, I'd like the engineer in you to answer the questions, not the lawyer to give another political statement. --[[User:AugustO|AugustO]] 06:11, 18 January 2013 (EST)
