@nospamblueyonder.co.uk says... E = mc^2 + 1/2mv^2 You are mixing up Einstein and Newton. The first part of this formula is Einstein Mc^2 Which has no meaning in Newton physics as in Newton physics where we have two laws. The law of conservation of mass. The law of conservation of energy. The second part in Newton is the value for kinetic energy. 1/2 mv^2 In Newton system the formula for energy is E= Kinetic energy + potential energy. -- It is scarily when you consider that kooky conspiracy theorist actually vote.

Newton could handle math and Einstein couldn't. The first part of this formula is Einstein Mc^2 No, that's Langevin, Not Einstein You already said what Einstein's formula was. Which has no meaning in Newton physics as in Newton physics where we have two laws. The law of conservation of mass. The law of conservation of energy. Up until Langevin, that was true. Einstein thought it was E= m (Definite integral 0 to v) sqrt(1-v^2/c^2)^3 .dv. See http://www.fourmilab.ch/etexts/einstein/specrel/www/ If you are going to teach history, at least get it right or stop trying to teach it. That integral belongs to Newton, by the way. Einstein isn't allowed to use the work of Newton. The second part in Newton is the value for kinetic energy. 1/2 mv^2 It sure is. In Newton system the formula for energy is E= Kinetic energy + potential energy. There you are wrong. Just because Newton hadn't discovered E = mc^2 in his lifetime doesn't mean those that followed him didn't. See "Evidence Against Emission Theories" J. G. Fox, Amer. J. Phys. 33, 1 (1965). E = mc^2 +1/2 mv^2. so E^2 = (mc^2 +1/2 mv^2)^2 I have no idea where you got your kooky formula from. Did you copy it from somewhere? You won't learn much that way. Androcles |

He may not have been a brilliant mathematician but he was pretty good. The first part of this formula is Einstein Mc^2 No, that's Langevin, Not Einstein You already said what Einstein's formula was. (a) I think you should do some checking on Paul Langevin. He derive E = mc^2 from Einstein's theories. Which has no meaning in Newton physics as in Newton physics where we have two laws.

Check Einstein mathematics in GR. He may not have been a brilliant mathematician but he was pretty good. Yes. It is a common misconception (paraded about by crackpots and the popular press) that Einstein was not able to do math. They cite that he failed math. In fact, he was a first rate mathematician, coming up with a notational methodology for repeated summation that is widely used in all branches of physics and many branches of mathematics. Einstein's failure at a mathematics course was not due to ineptitude, but lack of interest in the regimented structure of the classes he took in the gymnasium. |

I have it on good authority (;) that the first Ms. Einstein was being courted at the time as well... I nearly failed Controls Theory for just such a reason... David A. Smith |
