Re: Verifying physics at home

If using a spectrometer, wouldnt you also have to derive how it works? If Im doubting any experiment not done by me, then if someone hands me a spectrometer, its just a box with lights on that agrees with what you say. Sorry, you gotta build a spectrometer. And also prove why it works. Using first p...

Re: What if the second law was breakable?

So what impact does that have on the contraction of space?

Im not sure what the current state-of-the-art is, whether a "big crunch" has now been ruled out, but would it have the reverse effect? Would it suck energy out of systems? I cant quite get my imagination to work.

glue chair = plastic chair (it might not be the exactly right polymer, but its pretty danged close enough) Think about it - take a plastic chair: if made from wood of the same thickness, it would be extremely fragile, but a plastic chair is more than robust enough for some reasonably heavy-handed use.
