Equipment Definition and 154 Threads

I'm doing a research paper <again> and I need information on the Mars Rovers (Opportuniy or Spirit or both) and what materials make up those rovers and how physics is applied there etc...im really just starting to learn physics so i don't know much

Hi everybody, I'm working on a project aiming to determine what are the differents ways to measure the free energy (gibbs) and the enthalpy of solutions or any bodies. And I have no idea. If you know some equipment or some procedure to measure it, I would be very happy. Thanks.

I think, myself included [and mainly:smile:], there are people at PF that would like to know good testing equipment for electronics and such [multimeters etc]. Anybody with knowledge on the subject is welcome to suggest products and personal experience is very good also.
