A watt-second is NOT a fucking acceleration. It is a CHANGE in potential energy. It's easy to see why your step mother left you nothing. None of that means that you are not living off of the work ethic of your father who actually worked for a living and didn't run away fron it as you. You were no doubt a great disappointment to him. Your postings if you could even understand what you write would be a disappointment to you but you're not smart enough. > > > > 'Potential energy' is not work: https://www.youtube.com/watch?v=WeYsTmIzjkw -- Andrew Muzi am@yellowjersey.org Open every day since 1 April, 1971
