Physics 10: Physics for Future Presidents. Spring 2006. Professor Richard A. Muller. The most interesting and important topics in physics, stressing conceptual understanding rather than math, with applications to current events. Topics covered may vary and may include energy and conservation, radioactivity, nuclear physics, the Theory of Relativity, lasers, explosions, earthquakes, superconductors, and quantum physics.

I can appreciate the Irony of him talking about sound delay, when the vid's audio is out of sync!

mograf1 is kinda right on that, its escalating again with the war with georgia and russia now.

you dont explain ... ( 2 months ago by EliteSn1p3r)

you dont explain very well, and btw sound moves faster in water...not slower. It's easy to figure out how much slower sound is then light btw, it's 0.0000001% (~300,000km/s divided by ~330m/s). Sound doesn't always have a 3-5 second delay, it depends on how much space is between you and the sound generator! It'll have a 3 second delay for approx. each kilometre. Sound is an energy wave basically, it's atoms transferring energy between them as they collide.

When you talk, the ... ( 2 months ago by EliteSn1p3r)

When you talk, the vocal cords in your mouth vibrate, this transferes energy into the air in a series of rythmatic waves. These waves are a transfer of energy between the atoms, and as the waves move along the air they may eventually meet your ear drums. When the waves hit your ear drums they vibrate them, which sends waves of energy through a fluid in your ear which is then picked up by very fine hairs inside the liquid.

ya??? good ... ( 2 months ago by sspoke)

ya??? good explanation then? how does the nose work?? I haven't a clue all I know is oder must be a very weak gas atom chain that gets sucked up your nose like a vacuum cleaner and something happens.. maybe its biologically programmed to whatever it smells like based on pattern or maybe you just store it as you learn smells into a brain database or somethings

oh, nevermind, i ... ( 2 months ago by EliteSn1p3r)

oh, nevermind, i read you wrong when you said sound moves slower in water.

your smell is like ... ( 2 months ago by EliteSn1p3r)

your smell is like an advanced form of taste, the smell of something is given off by the same chemicals that give it taste. But apparently i read somewhere only a very very small concentration of oders are in the air in comparison too how much taste is in food. And that you can only distinguishe about 5 different types of tastes, but like 150 different types of smells. If you want to learn about it look it up..

Light is not ... ( 2 months ago by tramwell)

Light is not transmitted via atoms, light quantuums traversing the universe does NOT require any travelling atoms.
Considering sound waves, again atoms are not travelling anywhere too far, they just vibrate covering a distance comparable to the wave length of the sound.
Finally with constant energy you can of course accelerate a smaller body to a higher speed than a heavier one, but atoms of some cold gas might move slower than some celestial bodies. :) Peace.

So your saying ... ( 2 months ago by sspoke)

So your saying light is just a connection string which atoms give off when they cause a chain reaction of heat pattern? Try to put it in basic works.. I like understanding everything at the LEAST basic it could get.. and thats how I understand every law of universe.
I don't like hearing words like quantumms and goolguns and useless words like that.. the word atom was made atom for a reason 4 letters.. easy to access no stress on the mind. When you learn alot of information you get strain.

Nice lecture, ... ( 1 month ago by barrosTV)

Nice lecture, entertaining. Just for clarity: the comments right after min 20 are a bit outdated. Microscopes can now distinguish down to 0.3um with visible light, AND other microscopes like Electron or Atomic Force Microscopes can distinguish at atomic scale. So we can look at atoms, not the "electron cloud" though. Perhaps this seems nerdy, but well I believe that in Science we gotta keep an eye on details too. Go physics!

Thanks for sharing. It's my first acquintance with one of the Ivy League institutuions even if I'm in Penang, Malaysia now. Thanks for inventing You TUBE and thanks UCB for giving free videos. I dreamt my son Wallace will have a chance to study in your great university.

This isn't an Ivy League school. It's a very good school (maybe better than some Ivy League schools), but its not Ivy League. The Ivy League is an association of schools in the northeastern U.S. They have been (and will be) the same 8 schools for a very long time. They are: Harvard, Yale, Princeton, University of Pennsylvania, Dartmouth, Cornell, Columbia, and Brown.

I see. Thanks for the info. You are right it is still among the 5 star Uni in the world. Is it true Stanford U is your rival? In what aspect?

UCB is ranked number 1 public school in the world. Ivy leagues are private.
