@ophiolite::my notion on gaining energy means--if we throw a ball up at the highest point it has max. energy(potential energy)which we are supplying while throwing and when it comes down it comes with the same energy(albeit energy now being kinetic).......so the energy that we supply is recovered now in the form of kinetic energy/force of the ball . similar case with our cells..where is the energy gain going finally??

there is a star say 60 light years from us. a day comes say when it expands into a monstrous red giant and we note it on earth. when do you expect the event to have occurred on a time scale on that star: (a)60 years earlier or (b)at the time we observed it on earth....if anyone feels it as (a) then let me know how we cannot even perceive it's size increase......ie., in the sky, it's size should increase so how can we not observe it??

i am not a bio(major) but i have a doubt:: when we climb a flight of stairs obviously we are putting ourselves in a higher gravitational potential and hence higher energy state. so, we need to expend some sort of biochemical energy and hence feel a bit tired. but, when we get down even we feel tired(not that much) and according to me we even expend energy in this case.now, again considering the gravitational potential energy, we now need to gain gravitational potential energy(consider that we climb up and down the stairs with the same velocity so no change in kinetic energy)1. isn't this a violation of the energy conservation?? if not, then let me know how our cells/muscles store the potential energy gained by climbing down??

talking about a** makes the question/post a hottie and trendy

i have a wave function in spherical coordinates and i'll have to see if it obeys the uncertainity principle. then how do i do it without converting the wave function into cartesian coordinates???

can you let me know the heisenberg's uncertainity principle in spherical coordinates or atleast share a link from which i can get it

CPVC(chlorinated polyvinyl chloride) or PP(polypropelene) or LDPE(low density polyethylene)

i am doing my BS in chem engg.. can i take pure chemistry(physical) for my masters??
