OK, the microscope adjustment is too complicated to build from scratch. I am probably going to atttach the adjustment mechanism to my box. Problem is that I don't know what to buy/will be available at a general store that would have such an adjustment mechanism. does anyone have any suggestiosn?

aite lol. I have no engineering expierence but hopefully ill come up with something. ill post my designs when i do

thx for the response it has fixed volume. could you give me a sense of what the design would look like?

Hi, how does an adjustable chair/microscope work? I need to make an adjustable height box, and I need some basic understanding of the design. -Gary

sorry i don't know if I am supposed to release too much info from the research paper...but there are some equations there-i hope you can see them, because they reflect the things I need to study

I need more in depth/ specialized/advanced information than that

help! don't know what to study so I am a high school student,who has onlly studied basic physics (no AP). However, I am doing an ice engineering internship this summer, and I want to understand everything in my professors research paper. It seems like its very speciailzed to studying heat...

what does the symbol before the first "u" on the left side of the equation mean? It is found on this wiki page under the section "derivation in one dimension" http://en.wikipedia.org/wiki/Heat_equation the wiki page kind of just skipped a step, and didnt explain what the symbol...
