I begin the discussion by offering the following three laws: ▸ The laws of physicsScientific laws or laws of science are statements, based on repeated experiments or observations, that describe or predict a range of natural phenomena.https://en.wikipedia.org › wiki › Scientific_law
The laws of physics are the same for all observers in any inertial frame of reference relative to one another (principle of relativity). The speed of light in a vacuum is the same for all observers, regardless of their relative motion or of the motion of the light source.
Some inventions and contributions of Einstein are Avogadro's Number, Quantum Theory of Light, General Theory of Relativity, Special Theory of Relativity, The Photoelectric Effect, Wave-Particle Duality, Brownian movement, the relationship between mass and energy, Bose-Einstein Condensate, and many more.
He published the first part of his theory — special relativity — in the German physics journal Annalen der Physik in 1905 and completed his theory of general relativity only after another decade of difficult work.
Albert Einstein, in his theory of special relativity, determined that the laws of physics are the same for all non-accelerating observers, and he showed that the speed of light within a vacuum is the same no matter the speed at which an observer travels, according to Wired (opens in new tab).
His … general theory of relativity changed our understanding of space and time, becoming one of the two pillars of modern physics – the other being quantum mechanics. The German-born physicist's most famous equation, E = mc2, states that anything with mass has an equivalent amount of energy, and vice versa.
Albert Einstein's theory of relativity is actually two separate theories: his special theory of relativity , postulated in the 1905 paper, The Electrodynamics of Moving Bodies and his theory of general relativity , an expansion of the earlier theory, published as The Foundation of the General Theory of Relativity in ...
One more bit of Einstein/questioning lore: From my understanding, Einstein's theory of relativity began with an early “beautiful question” he posed, along the lines of “What if I rode a beam of light across the universe?” and then set out to answer.
Scientists have demonstrated that Einstein's theory of general relativity is correct to a remarkable degree of accuracy, despite having been around for more than a century.
Albert Einstein likely never took an IQ test but is estimated to have a 160 IQ—but even that can't stand up to these masterminds.
When you drive your car, E = mc2 is at work. As the engine burns gasoline to produce energy in the form of motion, it does so by converting some of the gasoline's mass into energy, in accord with Einstein's formula. When you use your MP3 player, E = mc2 is at work.
There were, in fact, unique features to Einstein's brain that may be the answer to how he was so smart. Some parts of the brain were thicker than average, which could mean he had a stronger connection between the two hemispheres. In 1947, he co-authored a top-secret paper on what to do if humans contact aliens with J.
Popular belief holds that Albert Einstein once said "There is no force in the universe more powerful than compound interest," and that he in fact invented the famous Rule of 72. The Rule of 72, as you may recall, tells us how many years are required for an investment to double, by dividing the interest rate into 72.
Einstein's 1915 general theory of relativity holds that what we perceive as the force of gravity arises from the curvature of space and time. The scientist proposed that objects such as the sun and the Earth change this geometry.
Newton's law of universal gravitation. Law of conservation of mass. Law of conservation of energy.
Einstein didn't believe in black holes
Today, the study and even imaging of black holes is standard practice. Einstein, however, wasn't convinced that black holes actually existed, despite the fact that they're directly descended from his general theory of relativity.
According to theoretical physicist Carlo Rovelli, time is an illusion: our naive perception of its flow doesn't correspond to physical reality. Indeed, as Rovelli argues in The Order of Time, much more is illusory, including Isaac Newton's picture of a universally ticking clock.
In this paper, Einstein proposed that light was not simply made up of waves, it could also be thought of as discrete, individual particles or quanta. This discovery would revolutionise physics and chemistry, because it would become one of the foundations of a new science: quantum mechanics.
"Two things are infinite: the universe and human stupidity; and I'm not sure about the universe.”
“Learn from yesterday, live for today, hope for tomorrow. The important thing is not to stop questioning.” “He who can no longer pause to wonder and stand rapt in awe, is as good as dead; his eyes are closed.” “A happy man is too satisfied with the present to dwell too much on the future.”
Path to general relativity
In 1907, Einstein had the "happiest thought of my life" when he was sitting in a chair at the patent office in Bern: If a person falls freely he will not feel his own weight.
A Relative Example
One example of relativity is to imagine two people on a train playing ping-pong. The train is traveling at around 30 m/s north. When the ball is hit back and forth between the two players, the ball appears to the players to move north at a speed of around 2 m/s and then south at the speed of 2 m/s.
The EPR paradox shows that a “measurement” can be performed on a particle without disturbing it directly, by performing a measurement on a distant entangled particle. Today, quantum entanglement forms the basis of several cutting-edge technologies.
Universal Gravity is a theory, not a fact, regarding the natural law of attraction.
