Best ResponseYou've already chosen the best response.1by the way , I think you meant to say dw:1364614621701:dw

Best ResponseYou've already chosen the best response.0it is an equation provided from the fractal study of energy consumption efficiency by mass

Best ResponseYou've already chosen the best response.1because unit for mass and energy doesn't match up hence they can equal each other

Best ResponseYou've already chosen the best response.0so our M is not mass :X since mass is small m in physics

Best ResponseYou've already chosen the best response.0Because Bigger animals need more energy to survive and smaller animals don't need as much because of their size.

Best ResponseYou've already chosen the best response.0no… M is still mass in that equation E is the energy consumption in calories? if we say that is the rate of metabolism (q) then what amount of energy required  how much calorie per gram? I think I stumbled on a very complicated living system processes :/ and may need a decade to get to fully understand

Best ResponseYou've already chosen the best response.0@Nubia9811 we know that bigger animals require more energy, but we are talking about the rate of efficiency. Meaning that big animals, like elephant, use energy more efficient than small ones like mouse. Let us say we need 10,000 mouse to be the same mass of an elephant, the sum of consumption of energy will be higher for the mouse compared to one elephant though they of the same mass.

Best ResponseYou've already chosen the best response.0can you do that alongside where E=M?

Best ResponseYou've already chosen the best response.1yes, http://www.wolframalpha.com/input/?i=Plot%5Bx%2Cx%5E%283%2F4%29%2C%7Bx%2C0%2C5000%7D%5D of course , we can see , it is much lower as mass increase

Best ResponseYou've already chosen the best response.1yes, we have to look for as mass get really big

Best ResponseYou've already chosen the best response.1that would be a deep question , wouldn't it?
