I know the heat transfer diferential equation, but I only saw it being used when the temperatures of the extremities of the material are fixed. Is there any phormula that aplies for situations where at least one of the extremities is free to change its temperature? Ex.: the left side of an...

By "agglutinate", I mean "stick together"; a thing that talc, cement and flour can do, but sand can not.

I saw a guy claiming to have studied geology and telling that "only dust of hydrated minerals could agglutinate, because agglutination is produced only by Van Der Wall forces". I read many times that dust can agglutinate without water traces, so I see this is wrong, but I would like to read...

By deep space I mean outside Van Allen belts. I would like to add one more question: I have heard about the Helen Dodson Prince classification for flares, http://ngdc.noaa.gov/stp/SOLAR/ftpsolarflares.html#cfi (botton of the page) wich can range from 1 to 17. It takes several new...

I read that coronal mass ejections and flares are independent things that can cause solar particle events. The particles emitted by the first travels at about 1,000km/s and can reach us in days, while the particles emitted by the last travels at near light speed and can reach us in minutes...
