What is it?

Did Einstein like the term "Relativity"? I know that Einstein referred to “Relativity” when he wrote or talked about his theories, but is it true that Einstein was not originally fond of the term “Relativity” to describe his theories by that name? I have found in a couple German publications...

The "Einstein Mith" NOw that we are in 2005 the so claimed year of physics, perhaps is time to speak about some of its greatest miths.. Einstein:= the proud discoverer of relativity,photoelectric effect and other...in fact did you know that the einstein formulation of Specific heat is not...

This to me means that everything is moving *through space* in some form or another. If we can calculate a slowest object it would be like finding a fastest time. Einstein dared not say it. If moving through space is what slows time then time can be both absolute and relative. The Fastest...

Garth has mentioned a few times in another context that Gravity Probe B is examining whether or not a rotating mass creates a distortion in space-time in the way that Einstein's General theory of relativity predicts. (Good luck Garth for SSC… My money’s on Einstein, though…!) I wonder if...

Please forgive me if I put this in the wrong forum, but I couldn't help but wonder...you know that UFOs defy the laws of physics, right? Well, What would Einstien say about UFOs?

I've been very much intrigued by this picture of the surface tension of water supporting a metal paperclip: http://www.visions-of-science.co.uk/winners2005/win-18.htm" "By photographing it using a grill in front of the light source, the deformation of the water caused by the clip's weight...

The recent PBS special, Einstein's Big Idea, is well worth watching (it's a history of e = mc^2). One reason is that in the first hour, it traces the historical development of the concepts of mass, energy, electricity and magnetism and electromagnetism in the 1700's and 1800's. One item of...

what about maxwell's equations/theroy states that the speed of light is constant in all refrence frames? (how'd enstien figure that to be true)

Given U^k_i, the components of U is a delta function i.e for i=k U^i_k =1, to prove it is invariant under Lorentz transformation~~ I don't know how to express it in Einstein summation notation, I am very confused with the upper-lower index, is it right to write the transformation in this...

In Volume 26, Number 6, November 2005 issue of European Journal of Physics, there is a special section dedicated to "Einstein and a Century of Time". There are several papers that discuss the historical issues of Einstein's work in SR and GR, and beyond... These papers are available FREE for...

I'm heading to this year's Nobel Conference in Minnesota. The topic is the Legacy of Einstein and the panels will consist of scientists in the areas of statistical physics, relativity, cosmology, and unified theories, who will discuss current work in the areas of Einstein's greatest...

I have to do a project in relation to Einstein on geo-reactors. What is a geo-reactor and what did Einstein say about it??Where can I find out more? Thanx

I came across a rather interesting website: [PLAIN ]http://www.relativitychallenge.com/index.htm [/URL] Steven Bryant explains how several of Einstein's equations that support the theory of Special Relativity are in error. He goes as far as to correct them and create a revised model he...

This site was linked at the top of the physics forums website. www.relativitychallenge.com I guess everybody has freedom of speech. Do people just get a kick out of proving Einstein wrong?

Read ALL of it: http://www.spaceandmotion.com/Theology-Albert-Einstein.htm BEFORE you reflect. This man has thought far too deeply and he must have read many books. If everyone on Earth developed this understanding there would be no need for so many religions and human unification...

I'm sure most of you have heard of the Einstein Referigeration Cycle . For those who have not I've listed the references for further reading.. http://www.me.gatech.edu/energy/pubs/SLA_2.pdf ok 342 K is about 156 F ,for anyone with an attic , it seems to me that this is the perfect solution to...

This guy is starting to get on my nerves. I should have guess that he was a creationist by the way he posts. He makes obviously wrong claims and gives no evidence for them. Not only does he give no evidence he does the creationist "Ignore all evidence to the opposite of what I am trying to say"...

Why did Einstein choose to define speed of light as a constant and time as a "variable" (relative to motion), rather than the reverse? I am aware of experimental results confirming constant speed of light and time dilation. But Einstein did not have those results at the time he proposed SR as...

Hello I am a teachers assistant for a one week summer camp class entitled "Time Space and Einstein" and are in ideas for demonstratiosn for the class. The class consists of students going into 6-8th grade. Anything that you think could keep the attention of kids who don't like equations or...

One morning Einstein was walking through beautiful rolling meadows and noticed that 3 cows were munching grass. What surprised him was that the cows had their heads through an electric fence mowing the grass that was on the neighbors field. The electric fence was supposed to prevent the cows...

I've a question here, is there a way to derive m'= \gamma m ? So far, i have not seen any derivation to this. I have heard that relativistic mass is a definition, but how did Einstein thought of this?

Hi, I need some help on a paper I'm writing about Newton versus Einstein. Basically I have to prove that Newton is the greatest physics person alive. I researched a lot online and found that Einstein basically copied Newton's findings and added the fourth dimension to make it look it was his...

hi, can anyone tell me where can i get 'Young Einstein' by Patrick Pringle on the net for free?

"I came to America because of the great, great freedom which I heard existed in this country. I made a mistake in selecting America as a land of freedom, a mistake I cannot repair in the balance of my life." I wonder because with all the anti-American people I've known, i have yet to hear...

Here I'd like to present theories of professor of physico-chemistry, Ph.D. Najip Valitov from Russia, who discovered new theories after Einstein. Part of his discoveries are described in his web-page: [PLAIN]www.bashedu.ru/ValitovNKH.htm[/URL] In 1972 professor Valitov, who lived in the...

Hello all, I have a quick question on Einstein notation. I'll write the tensors as a capital letter and the covariant indices as lower case letters (and not use anything that has contravariant indices). I'll also use != for not equal or not congruent to. In Schaum's outline of tensor...

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?
