the room temperature is 25 degree celcius, while our body temperature is 37 degree celcius. So, we are hotter than the surroundings.

We have also known that black is a good emitter of heat, as compared to white.

So, when we wear a black shirt, we should be emitting heat faster to the surroundings, as compared to a white shirt, thus making us cool faster. However, it is wearing white shirts which will make us cooler.

What is the flaw in my concept? I've tried to find the answers, but to no avail.

Thanks.

Sorry for the technical question but does anyone out there work on EMs.

Basically I work on a protein which has two different conformations (which can be distinguished under an EM) I just need a way of describing the abundances of them beyond 'there looks like theres more x than y'. So I can put some numbers to my data.

Does anyone know if there is a standard technique for this out there? And what it would be called so I can do a proper PubMed search (or even better a citation). Ahhh There's never anyone in the EM section when I need them.

Thanks

Why is it that I can remember little unimportant events that happened in my childhood over 20 years ago, but I can't remember what I wore last Monday? I know major events or traumatic events that happened in your life your brain will remember for years, but I can remember one particular day sitting in my elementary school classroom listening to the teacher talk about some uninteresting fact. I cannot remember any other days immediately surrounding this one event. So, I'm a just wondering if any of you science minded folks know how your brain decides which little events to pick out from your past and store permanently in your memory?
