Physics 10 - Lecture 01: Atoms and Heat

Cheap skates! So in all the books i have read (you would probably hate them - mysticism an all that) they were twisting words. Oh well; cant say im not dissapointed but its good to know the truth. Thank yous. (o:

the toyota ad lol

i dont even know why i cliked on this, yawn lol

I like your state of mind. People interpret the world around the acording to their opinions and one persons beliefs are no more correct than anothers. Dont the results of quantum mechanics experiments depend upon the observers??

When a physic says "observer" and "observation", (s)he refers to the measurement apparatus and the measurement value it produces, not the persons conduction the experiment. In this sense it turns out that the observation (the measurement) in q-mechanics indeed is dependent on the observer (the measure apparatus).

How nice. Im only slightly bothered. (o: Still; nobody answered my questions. If when things get colder the paticles move less and take up less space why does water expand when you freeze it? I said we have never seen atoms which the prfessor denies. The Japs rendered their planes invisible by painting them (recently) with a paint with a color that was outside of our vissible spectrum. Is the thing we see through an electron microscope just a computers interpretation??

Nothing says things must take up less space with lower temperature. The space configuration of solid water is larger than liquid water. Water close to freezing will start take up more space as it adjust to is solid state.

Black is "no color". The paint you refer to is probably radar paint, which absorb radar waves and make the radar signature much smaller.

Atoms are seen indirectly. But everything is seen indirectly. What we see is not the real object but interpretation of bounced photons.

well it's there first lecture im sure that he is just re introducing them back in to something that they may have forgot

this is lame
