A Quote by Brian Greene
Evidence in support of general relativity came quickly. Astronomers had long known that Mercury’s orbital motion around the sun deviated slightly from what Newton’s mathematics predicted. In 1915, Einstein used his new equations to recalculate Mercury’s trajectory and was able to explain the discrepancy, a realization he later described to his colleague Adrian Fokker as so thrilling that for some hours it gave him heart palpitations.

We went to the moon using just Newton's laws of motion and gravity. Newtonian dynamics we call it. So then we find out, "Well, this works because there's certain regimes we've never tested it in." Had we done so, we would show that it didn't work: For example, at very high speeds, very high gravity, Newton's laws fail. They just fail. You need Einstein's laws of motion and gravity. Those would be his special theory of relativity and general theory of relativity. Now you invoke those and it works.
By the time 1967 had rolled around, general relativity had been relegated to mathematics departments... in most people's minds, it bore no relation to physics. And that was mostly because experiments to prove it were so hard to do - all these effects that Einstein's theory had predicted were infinitesimally small.
Einstein and the Quantum is delightful to read, with numerous historical details that were new to me and cham1ing vignettes of Einstein and his colleagues. By avoiding mathematics, Stone makes his book accessible to general readers, but even physicists who are well versed in Einstein and his physics are likely to find new insights into the most remarkable mind of the modern era.
Relativity was a highly technical new theory that gave new meanings to familiar concepts and even to the nature of the theory itself. The general public looked upon relativity as indicative of the seemingly incomprehensible modern era, educated scientists despaired of ever understanding what Einstein had done, and political ideologues used the new theory to exploit public fears and anxieties-all of which opened a rift between science and the broader culture that continues to expand today.
In grownups, mercury can cause memory loss, tremors, vision loss and numbness of the fingers and toes. It can also adversely affect fertility and blood pressure regulation, and a growing body of evidence suggests that exposure to mercury may lead to heart disease.
Only Freddie Mercury could do Freddie Mercury. He was absolutely brilliant - I loved him to pieces, and I had a great deal of respect for him.
Most of what Einstein said and did has no direct impact on what anybody reads in the Bible. Special relativity, his work in quantum mechanics, nobody even knows or cares. Where Einstein really affects the Bible is the fact that general relativity is the organizing principle for the Big Bang.
Most people who have encountered mercury have done so after breaking a mercury thermometer. And many of us who saw the liquid balls of mercury scatter across a floor or countertop considered the element the most beautiful on the periodic table.
When general relativity was first put forward in 1915, the math was very unfamiliar to most physicists. Now we teach general relativity to advanced high school students.
Srinivasa Ramanujan was the strangest man in all of mathematics, probably in the entire history of science. He has been compared to a bursting supernova, illuminating the darkest, most profound corners of mathematics, before being tragically struck down by tuberculosis at the age of 33, like Riemann before him. Working in total isolation from the main currents of his field, he was able to rederive 100 years' worth of Western mathematics on his own. The tragedy of his life is that much of his work was wasted rediscovering known mathematics.
As for mercury, a child will almost certainly get more mercury exposure from her immediate environment than from vaccination. This is true, too, of the aluminum that is often used as an adjuvant in vaccines to intensify the immune response.
More philosophically-minded critics regarded Einstein's argument for relativity as little more than a logical bait-and-switch ploy: "[T]he supposition of most expounders of the Special Theory, that Einstein has proved the relativity of simultaneity in general - or that his 'simultaneity' is something more than a logical artefact - must manifestly be given up.
Pythagoras used to say that he had received as a gift from Mercury the perpetual transmigration of his soul, so that it was constantly transmigrating and passing into all sorts of plants or animals.
Groucho Marx, in his later days, gave me the best review I've ever had and probably will ever have. I changed a light bulb over his bed, and when I came off of his bed with the used one after putting the new one in, Groucho said, 'That's the best acting I've ever seen you do.'
A. Douglas Stone, a physicist who has spent his life using quantum mechanics to explore striking new phenomena, has turned his considerable writing skills to thinking about Einstein and the quantum. What he finds and makes broadly understandable are the riches of Einstein's thinking not about relativity, not about his arguments with Bohr, but about Einstein's deep insights into the quantum world, insights that Stone shows speak to us now with all the vividness and depth they had a century ago. This is a fascinating book, lively, engaging, and strong in physical intuition.
The action of the child inventing a new game with his playmates; Einstein formulating a theory of relativity; the housewife devising a new sauce for the meat, a young author writing his first novel; all of these are in terms of definition, Creative, and there is no attempt to set them in some order of more or less Creative.
