Einstein Definition and 811 Threads

A friend of mine recently put my attention to this streaming video advertisement for an entheogenesis conference on Pot-TV: http://pot.tv/archive/shows/pottvshowse-3398.html In it there is a reference to a prof. Francis Thackeray from South Africa (and a prof. Vandemir[?]; not sure if I made...

This is an interesting point that I just thought of while listening to one of Einstein's own lectures on his theory of relativity. In it he said that energy is equal to mass times the velocity of light squared. But doesn't velocity have direction? And wouldn't this imply energy has direction...

I see there is an "Einstein Conference" in the Canary Islands coming up real soon. http://nti.educa.rcanaria.es/fundoro/einstein_2nd/einstein_info.htm Does Anyone no of anything like it going on in USA or Canada, as this is 100 years for SR??

If we cool down a small sample of atoms and see bose-einstein condensation, and so the speed of the atoms is slowed down dramatically, what can we say about the speed of the sub-atomic particles (quarks etc..), do we know how their speed is being changed? regards, marcel

For more than 70 years, QM advocates have misrepresented Einstein's EPR work. Once it becomes clear what Einstein was really saying, it should be very difficult to stick with Bohr's bizarre interpretation of entanglement. Among the FEATURE ARTICLES (Cover Story) of the Scientific American...

Do you agree than Albert Einstein was basically an atheist? There seem to be rumors that he was not, after all, he did use the word "God" on many occasions. However, I am pretty sure that his "God" was a synonym for Nature. Here is what Einstein had to say: "From the viewpoint of a Jesuit...

How do I replicate the Einstein - de Hass Effect experiment? I know the basic premise: hang a slender iron rod inside a ring magnet and it should spin as the electrons all line up, to conserve angular momentum. Are there any websites detailing how to conduct/build/recreate this experiment...

From http://mathworld.wolfram.com i see that the integral notation was "the symbol was invented by Leibniz and chosen to be a stylized script "S" to stand for 'summation'. " So from that i figure integrals are just summations. So what's the difference from Einstein Summation, where "repeated...

In another thread dextercioby posted the http://https://www.physicsforums.com/showpost.php?p=406225&postcount=13 I want to address this interesting comment here so as not to divert the other thread. dextercioby - What's Q theory? I assume that it pertains to quantum mechanics?? I thought...

Where can I get a copy of the paper Theodor Franz Eduard Kaluza, sent to Albert Einstein. Any help would be greatly appreciated. Regards Terry Giblin

2005 is the centennial of einstein's 3 papers (special rel, E=mc2, photons and the photoelectric effect) and the year has been named the Year of Science on 18-22 July 2005 there will be conference in Paris called "Eintein Century" or "Einstein2005" conference there is the list of the 24...

Yeah i have to write a 20 page paper on the Albert Einstein debate of 2004 in january sometime. I can't find anything about it I am currently a senior and am not a big math/physics person so if anyone has any information about it could you please help me out thank you. -Justin

Several years ago, while I was thinking about dark matter and how we had misplaced 96% the matter in the universe, I realized that something was very wrong with how we perceived matter and that something was fundamentally wrong with physics. To think that 96% of the matter in the universe is...

The Brain of Einstein, a Question I have a foggy understand of Special Relativity, and understand that it was understood previously without a real theory by Lorenz, but the General Theory was such a shot coming out of nowhere, without physical validation, that is impossible to understand the...

At waht temp will the heat capactiy at constant volume of a substance achieve one third of its classical value of 3R? Express in terms of Einstein temperature Te. 3R = 24.9 J/ mol K R = 8.314 J / mol K = 3R (\frac{Te}{T})^2 \frac{e^\frac{Te}{T}}{e^\frac{Te}{T} - 1} But i don't know...

When you apply a vertical magnetic field to a metallic cylinder suspended by a string it begins to rotate. Why does it do so? Thanks //Henke

Thermodynamics textbooks indicates that the total energy of a system E is given by the following equation E = U + Ek +Ep where U is the internal energy due to atomic or molecular interactions, Ek is the kinetic energy due to the velocity of the system ,and Ep is the potential...

http://www.thefinaltheory.com/pages/1/index.htm Have you guys seen this yet! The author is crazy. :eek: :eek:

I've got my asbestos suit on, boys and girls. : I was searching for links to Einstein's 1912 paper where (according to Renada) he said that the speed of light in a vacuum is only constant in a space-time domain with a flat gravitational field strength. Then I bumped into this...

Hi friends! Can we understand what he meant about his theory? Or did he want to tell us such different things?

Simply Einstein: Relativity Demystified by Richard Wolfson Undoubtedly one of the best primers on special and general relatively in my view. Finished reading it a few weeks back and am delighting in dipping into various sections again. By far the best book I've read on the topic so far - and...

Okay, everyone knows about the twins paradox, you know one twin flies around near the speed of light in a spaceship or whatever and when he comes back he's 50 years younger than his twin brother. Well... according to relativity you can reverse any motion and say that the universe is passing by...

I remember reading somewhere that some Law of Newton was wrong according to Einstein's theories. Does anyone know something about this?

what were they all?

Paul Dirac said that Einstein didn't need new experimental data to produce a new theory.And he also said that infinities should not appear in a theory that is correct.What do people on theory development think about these remarks made by a man respected for the depth and clarity of his theories?

Almost a hundred years ago leading scientists were discussing the fact that if the most elemental constituents of mass all moved at the invariable speed of light, the phenomena of relativity would be a natural consequence. This, of course, required the classical space-time. Has anyone ever...

Hello friends, Einstein proved that if an object travels in a vacuum nearly at the speed of light, the result will be that the object will be transferred into future. One of my proffesors said that if a rocket travels round the Earth in space, with the speed of light for 1 year, then already a...

Most physics books says something like this on the photoelectric effect: "the photoelectric effect provided strong evidence of the particle nature of light - and it eventually led Einstein to propose that light consisted of discrete packets of energy (photons) in 1905." I have been told...

Like anyone other than Stephen Hawking... =-/

I hope this is being placed in the right forum. I am still getting acquainted with PF. The "no dice" post in quantum got me thinking...was Einstein schizoaffective ? I know very little about him other than his brain size was different...i think. Does anyone know how? When I...

Finally something interesting in the news. Check it out . http://www.cnn.com/2004/TECH/space/04/02/einstein.satellite.ap/index.html

How can I obtain a Kerr metric by using the Einstein equation?

Was Einstein really a genius or just someone clever with new ideas? SR is really a simple theory and uses many ideas from other scientists. Clearly he was creative, but was he a genius[?]

Hello there! I asked this question in a different forum, and was directed to ask this here: ---- My next question also involves Einstein. It's about gravity not really being a force or whatever. According to the program the Earth revolved about the sun because the sun warps the space time...

Heya guys I have a few general questions. The first one is about Stephen Hawking. How does he express his ideas these days? I saw a thing about him on TV today and it seemed as though he has extremely limited motor function in his hand, and he can't speak, except for the text-to-speach...

Please, take a look at the last paragraph of the http://www.aliasabur.com/nytimes.html then read the whole article and answer my question.

I was reading the other day about John Tyndall, who I believe was the first person to discover that because blue wavelengths are relatively short, they scatter and disperse more than red wavelengths. At this point I remembered that Einstein’s original theory of relativity had included a...

Ok. I have a question on SR/GR with regards to Einstein. How did he come up with this? That's what I don't understand about physics and physicists. How do they derive a formula that represents what they are trying to express? And especially with regards to Einstein. His relativity...

The difference between us and einstein is that he thinks every basic concept of the physics extremely logically. Logically means he goes back to the origin of the theory and starts connecting the basic concepts until he reaches the desired concept. Its like you go to root of the tree and start...

Section 11.6 of Ray D'Inverno's book Introducing Einstein's Relativity This section shows Palatini's approach in using an equivalent Lagrangian to obtain the vacuum field equations of GR and the connection. From equation 11.39, we already have...

I read somewhere that the roots of SR can be traced back to Einstein's childhood. I wish I could remember where I read it, but I can't. (for some reason I am leaning towards "The Universe in a Nutshell") It said that when he was a boy (11 years old, I believe) he went to the beach with his...

if Einstein sits in front of you now, what would you like to ask him? for example: what do you think about experimental success of bose-einstein condensation. certainly he will not believe me.

A friend of mine asked me this question Does anyone know the answer? Thanks Pete

Hello everyone I am new to PF actually this is my first thread. I am looking for the equation to see how far and how, the radiation from the Nuclear Blast using E=mc^2. Can anybody help? Please[?] Nicole

An experiment by Italian scientists using data from NASA's Cassini spacecraft , currently en route to Saturn, confirms Einstein's theory of general relativity with a precision that is 50 times greater than previous measurements. Link.

John Baez just posted this announcement and tentative schedule for a conference this month at the Albert Einstein Institute (Max Planck Institute for Gravitation Physics) on the outskirts of Berlin. We have had several threads at PF studying work by AEI people---Hanno Sahlmann, Martin...

Does Bose Einsteine Condesate violate the Pauli Exclusion Principle?

I was just doing some thinking, but some of the things Einstein has said over the years is just downright unacceptable. For instance, when he said his famous saying pertaining to Heisenburg's uncertainty principle and how it explains quantum mechanics,"God does not play dice." Now, I know...
