Albert einstein Definition and 45 Threads

I read these lines from the book Ideas and Opinions by Albert Einstein- "Gradually the conviction gained recognition that all knowledge about things is exclusively a working-over of the raw material furnished by the senses." what I interpret from is that knowledge is obtained by observing...

Hello, I am trying to find in which book Albert Einstein wrote something. I will appreciate any help. The adage i am trying to find is: Education is not the learning of things , but the education of the mind so that it can think. Thank.you

Assumption: Object 1 is moving and object 2 is static. It is impossible to say which object is moving without any reference object 3. There are three scenarios possible. 1. Reference object 3 is at same position in space time with object 2, then object 1 is moving and object 2 is static. 2...

Some of the most profound statements on the nature of science have come from Albert Einstein, one of the greatest scientists of all time. What do you think Einsteine meant when he said: "The most incomprehensible thing about the world is that it is comprehensible"?

I am glad that this Summer I was introduced to an awesome novel, The Other Einstein. The book is the fictional portrayal of Mileva Maric, the wife of my favorite scientist Albert Einstein, and her struggles to balance life and work. The author has done a good job in researching the life of...

Hi All This is an outgrowth of the following thread: https://www.physicsforums.com/threads/light-photons-waves-particles-wave-particle-duality.934063/ OK first we need to clear up a few misconceptions about Einsteins view of QM. It is often said Einstein didn't believe in QM. That's really a...

Homework Statement If someone on a spaceship looked at a clock on Earth traveling at 99.5% the speed of light what would they notice? Homework EquationsThe Attempt at a Solution Would they notice that time is faster on earth? Is my assumption correct

Greg Bernhardt submitted a new PF Insights post How Well Do You Know Albert Einstein? Continue reading the Original PF Insights Post.

I am writing an essay on "Ziemlich Frech : Einstein versus Nernst". I can find very little information on this topic anywhere. I've searched the library and the internet and don't have anything certain yet. So far I'm at a stage where I believe it could be about Einstein Solids. I know that...

I am a new member! I am very much interested and want to pursue theoretical cosmology. I am currently a class/grade 10 student!

Hi I just started on my fourth year of a masters degree in mechanical engineering, and I got this fluid mechanics course that is nothing like anything I have had before. This course is based on finding expressions using Stokes equations. Combining and deriving momentum, continuity and energy...

This is not a joke. Suppose Albert Einstein was born in 1979, not 1879, and to date had not written any articles. Like the old Albert, modern Albert works for a government department. He assesses applications for arts grants. You see, unlike the old Albert, modern Albert studied art after...

GENERAL: Only two things are infinite, the universe and human stupidity, and I'm not sure about the former. Albert Einstein Common sense is the collection of prejudices acquired by age eighteen. Albert Einstein The fear of death is the most unjustified of all fears, for there's no...

History question: I searched all over the web and cannot find the answer. I knew that Albert Einstein earned his phd from university of zurich. from wiki: In 1900, Einstein was awarded the Zürich Polytechnic teaching diploma. (Between 1900 to 4/30/1905, I deduced that Einstein was unemployed and...

What led Albert Einstein to conclude that space and time were not two separate entities but merely one spacetime. Also, has there been experiment to prove this notion?

Hi, I have recently become very interested in physics. I feel like having a good physics background allows you to properly grasp everything that is going on around you and ultimately the Universe. I am very eager to learn about how things work, about light, energy, Isaac Newton's laws, Albert...

Not sure if this is the best location to ask this lol, I find myself at a quandary, I'm an avid reader and I'm looking for more textbooks to add to my collection. Preference on the technical side. I prefer seeing the related metrics etc. Textbooks I already have. "First three minutes" by...

One problem in understanding Special Relativity is that it is intuitively hard to agree with relative simultaneity. My major problem is that I cannot quite answer the question: Is relative simultaneity a real effect or only a mathematical artifact of Lorentz transformation? I am not...

Answer one and then ask your own, be creative! :) Would you rather... Have lunch with Issac Newton or Albert Einstein

Hello To demonstrate that we can deduce from special relativity the existence of an observer who finds that his three-dimensional space is not euclidean (a conclusion that is false in my opinion), in subsection "Behaviour of Clocks and Measuring Rods on a Rotating Body of Reference" of his...

Below is a list of physicist I compiled, and there achievements. I have sources if you want them. Do tell me if there is any more I should add or anything I should add to their bios, thanks in advance.θ Richard Feynman (1918-1988) Developing Path Integral Formalism of Quantum Field...

I'm concerned about your book. I got up to this part: And I got very concerned. Although what you say is true, the fact that you put the last part of the quote in a box, like you did for what you called the Fundamental Principle and its restated version, gave me the impression that you...

Hello all, I am currently applying for math REUs and I was wondering if anyone would help me proof read my essay and criticize it (as much as you'd like please). I know most of them accept mostly juniors and seniors, but I really want to get into at least one of the programs so that's why I...

How Albert einstein proved this equations that I referred at the title? He proved that with maths or with observation?

Hi all, What is the Hamiltonian or main equation, that if you solve it, parallel universes are predicted? For example, the Dirac equation, if solved, predicts the existence of anti-particles. If You solve Maxwell's Equations, you predict there should be E & M waves. Solving certain...

In 1953 Albert Einstein wrote to the Cleveland Physics Society on the occasion of a commemoration of the Michaelson–Morley experiment. In that letter he wrote:[1] What led me more or less directly to the special theory of relativity was the conviction that the electromotive force acting on a...

Hello, Some consider Albert Einstein, some think it was Galileo Galilei, some consider that E=mc^2 formula revolutionized the entire picture of physics, some consider James Clerk Maxwell's equations of electromagnetism. I consider it was Sir Isaac Newton. Newton can be well considered as...

At the moment, I am reading the book Relativity, written by Albert Einstein regarding his special and general theory of relativity. In his introduction to general relativity, he poses a thought experiment: Suppose we have a large chest in space far away from any appreciable mass (stars...

The Case Against The Word "Aether" Many BSM theories involve a space-time that has properties rather than being "nothing" or omnipresent field or substance, but the word "aether" as a description for that "non-nothing" vacuum between Standard Model particles is long past its due date as a...

Hey folks i got a doubt, one of the theories of Albert einstein say everytime we run for example our mass become a little tiny for example one person have 80 pounds when you start run you have for example 79 pounds of weight because of the speed, and when you stop running your mass go back to 80...

The quote is from Jake Goldberg's Albert Einstein: the rebel behind relativity: p. 53: "As objects begin to move rapidly through the dimension of space, their movement throught the dimension of time must slow down, because no object can move through space-time faster than the speed of light."...

Dear Professors and learned readers, The book Relativity: The General and Special Theory by Albert Einstein is, in my opinion worthy of discussion in this forum. My particular questions concerning this book are: 1. Why do you think it not used in high schools since the author recommends this...

Here's a shorter article for your review. Any errors? ---- I was wondering, how did Albert Einstein figure this out? So I got an English translation of the original article, which is entitled "Does the Inertia of a Body Depend On It's Energy Content?" This article is only a page long...

Hello. I have just regestered to tell the world of my amazing theory. I have called it, Binary universe. Albert Einstin said that everything puts a dent in spacetime. If sapce is flat, there is 2 sides witch means 2 universes. One is ours, an there's another one. I call it UB ( Universe B)...

Error in special relativity Albert einstein assumed (in the time dilation) a box-car moving with velocity V with a mirror in its ceiling and observer 1 sitting in the box car holding flash light vertically so when he sends a flash pulse , this pulse will go vertically , hit the mirror , and...

http://www.youtube.com/watch?v=wRRNeAilrnM" I thought this short 4 minute video was worthwhile, it presents a brief summary of Einstein's life and why some professional psychiatrists say that Einstein was a high functioning autistic. His own words seem to reinforce that view below: see...

Okay, I have heard that Albert Einstein wasn't really into this whole idea of quantum mechanics. What was some of the reasons for this?

If both Isaac Newton and Albert Einstein are still alive today, imagine the world we will be living in and the impact on all theories of physics! Can you imagine what the world will be like with them still around?

The following is the Einstein’s train but instead of train consider two airships of equal in lengths. http://www.youtube.com/watch?v=wteiuxyqtoM&feature=related Both are moving with same speed but opposite in direction. After certain time they cross each other such that one is exactly...

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

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

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...

I've been reading the book Relativity by Einstein, but need some things cleared up. I have only studied physics in college (took both mechanics and topics pertaining to more smaller scale phenomenas) and have a vague familiarity with concepts of physics but would like to expand on this a bit...
