Good lecture series on a very complex topic.
Kudos to the professor

[gpcrawford]

At last Marcel Grossman gets a mention in discussing general relativity most others leave the collaboration between Einstein and Grossman out . Not that I understand the mathematics .

[kingkhann]

Consise lecture series for a good grasp on the subject

NIST WTC FAQ 31 answer from NIST "Since the stories below the level of collapse initiation provided little resistance the building section above came down accelerating essentially in free fall." Einstein, "free fall is the equivalent to floating, doing absolutely nothing, and being weightless in deep space."

Two spaceships are heading towards each other. The radar on each ship indicates the other ship is accelerating towards it. However only one of the ships is actually accelerating. The accelerating ship is the entire Saturn V Rocket, with lots of inertia. The non accelerating ship is just the tiny Apollo space capsule, with very little inertia. The crew in the accelerating one are accelerating @ 1G. and will be able to sit in chairs with their coffee in cups sitting on a table, just like here on earth. The acceleration they see out the window of the Apollo capsule is just visual acceleration. In the Apollo capsule the crew will be floating around weightless, just like falling off a roof in free fall. There will be a huge collision when the huge rocket crashes into the tiny capsule. But wait a minute, if the huge rocket only started to accelerate from a distance of 12 feet away, like the distance separating the north tower's 95 lower floors from the falling upper 12 floors, then only a relatively slight collision would occur. Now the Saturn V will have a bit more inertia to push, and the cruise control would add a slight more thrust to maintain the 1G.

Hey, Copernicus was Polish, he was a Catholic and was a cannon (although not a priest) in Krakow though his life.

At the very beginning you say the course is 20 lectures. I only see ten. Where are the other ten? thx

The atomic gravity hypothesis is impresssive, search "atomic gravity theory".

[ericsu]

The theory of general relativity is invalid because it predicts the angular difference between the aphelion and the perihelion to be 2 radian for the orbit of Mercury. The actual observation is about 6.28 radian. More in

There is a lovely, cute and perhaps hiper intelligent :3 woman in this video! haha Who are you? 7:04
