On a hot hot summer day I like to go to local supper market to buy a tub of my favourite ice cream that bring home in shopping bag. It is hot hot outside the bag, and it is frozen cold ice cream inside the bag.

Now, according to the first law of thermodynamics, heat always flows from a reservoir (an object at high temperature) to a sink (a object at low temperature) when both are placed in contact with each other. The mode of heat transfer this way is called conduction of heat energy.

The question is - if heat flows from hot outside the bag – the big giant reservoir at about 35 degrees – to the cold ice cream inside the bag - a sink for heat below zero degree. Then why the bag, in the path of the heat flow, should get cold?

I have to do them next semester and It's only wise to put in some work during the holidays. Anyhows, like, is it as simple as SineA/a= SineB/b= SineC/c? With the / sign denoting division. Is that all we need to know? It couldn't be that simple, could it?

there are many types and subtypes of glaucoma the open angle and the one which is narrowed or blocked angle glaucoma. There are many drugs used to manage these types of glaucoma. I have found out that adrenergic agonists(sympathomimetic) /alpha agonists are used to treat OPEN ANGLE glaucoma. My question is 1. why are these adrenergic agonists used in glaucoma when in fact they mimic the sympathetic response they cause pupillary dilation which increases intraocular pressure which is contraindicated in glaucoma, please explain how it can help in glaucoma if it causes pupil dilation? I have also found out that beta blockers(sympatholytic) suppress the sympathetic response causing pupil constriction decreasing intraocular pressure which helps in glaucoma. Cholinergic drugs/parasympatholytic mimic parasympathe response also helps by pupil constriction. and for open +narrow glaucoma 2. is my understanding correct? which drugs are used for which type? 3.why are benzodizepines not for glaucoma

it is known that there exist real positive numbers θ such that the integer part of θ^3^n is a prime number, for all positive integers n. The least such number is called Mills' constant and is approximately

1.30637788386308069046...

http://en.wikipedia.org/wiki/Mills%27_constant

My Question:
Is there any reason why Mills has chosen the number 3 in his formula.
It's obvious to me that one can chose any real number k > 1 so that Int(θ^k^n) gives also prime numbers for each n.
Of course we will get a different θ if k is not 3.
