Verified Einstein Quotes

The generalized theory of relativity has furnished still more remarkable results. This considers not only uniform but also accelerated motion. In particular, it is based on the impossibility of distinguishing an acceleration from the gravitation or other force which produces it. Three consequences of the theory may be mentioned of which two have been confirmed while the third is still on trial: (1) It gives a correct explanation of the residual motion of forty-three seconds of arc per century of the perihelion of Mercury. (2) It predicts the deviation which a ray of light from a star should experience on passing near a large gravitating body, the sun, namely, 1".7. On Newton's corpuscular theory this should be only half as great. As a result of the measurements of the photographs of the eclipse of 1921 the number found was much nearer to the prediction of Einstein, and was inversely proportional to the distance from the center of the sun, in further confirmation of the theory. (3) The theory predicts a displacement of the solar spectral lines, and it seems that this prediction is also verified.

Albert Einstein once said, “Most people say that it is the intellect which makes a great scientist. They are wrong: it is character.” . . . On one level, science is a collection of facts about the world, and adding to that collection does require discoveries. But science is also something larger. It’s a mindset, a process, a way of reasoning about the world that allows us to expose wishful thinking and biases and replace them with deeper, more reliable truths. Considering how vast the world is, there’s no way to check every reported experiment yourself and personally verify it. At some point, you have to trust other people’s claims—which means those people need to be honorable, need to be worthy of trusting. Moreover, science is an inherently social process. Results cannot be kept secret; they have to be verified by the wider community, or science simply doesn’t work. And given what a deeply social process science is, acts that damage society by shortchanging human rights or ignoring human dignity will almost always cost you in the end—by destroying people’s trust in science and even undermining the very conditions that make science possible.

Many people have difficulty contemplating the human soul. They think that an immortal, massless entity with no dimensions that exists outside space and time is inherently preposterous. But they are perfectly willing to accept the existence of light. Yet what is light? Einstein’s special theory of relativity says that it is an immortal, massless entity with no dimensions that exists outside space and time. Hasn’t the penny dropped yet? Since Einstein, we have had scientific proof, verified by countless experiments, that something completely uncontroversial and unquestioned – light – has exactly the “physical” attributes commonly assigned to the soul. So, is it any longer tenable to assert that the concept of the soul is scientifically ridiculous? If it is then the concept of light must be equally ridiculous. If we took one further step of attributing mind to light, the theory of light would become the theory of souls.

Things have becone even more mysterious. We have recently discovered that when we make observations at still larger scales, corresponding to billions of light-years, the equations of general relativity are not satisfied even when the dark matter is added in. The expansion of the universe, set in motion by the big bang some 13.7 billion years ago, appears to be accelerating, whereas, given the observed matter plus the calculated amount of dark matter, it should be doing the opposite-decelerating. Again there are two possible explanations. General relativity could simply be wrong. It has been verified precisely only within our solar system and nearby systems in our own galaxy. Perhaps when one gets to a scale comparable to the size of the whole universe, general relativity is simply no longer applicable. Or there is a new form of matter-or energy (recall Einstein's famous equation E=mc^2, showing the equivalence of energy and mass)-that becomes relevant on these very large scales: That is, this new form of energy affects only the expansion of the universe. To do this, it cannot clump around galaxies or even clusters of galaxies. This strange new energy, which we have postulated to fit the data, is called the dark energy.

Patience is not a hallmark of the press, especially in the Internet age of rapid fire news reports. The media hungrily gobble content as long as they can make the case that it is new and interesting to the public. Unpublished reports, speculations, preliminary review process sometimes become as newsworthy as meticulously verified conclusions.

Are [the arts and the sciences] really as distinct as we seem to assume? [...] Most universities will have distinct faculties of arts and sciences, for instance. But the division clearly has some artificiality. Suppose one assumed, for example, that the arts were about creativity while the sciences were about a rigorous application of technique and methods. This would be an oversimplification because all disciplines need both. The best science requires creative thinking. Someone has to see a problem, form a hypothesis about a solution, and then figure out how to test that hypothesis and implement its findings. That all requires creative thinking, which is often called innovation. The very best scientists display creative genius equal to any artist. [...] And let us also consider our artists. Creativity alone fails to deliver us anything of worth. A musician or painter must also learn a technique, sometimes as rigorous and precise as found in any science, in order that they can turn their thoughts into a work. They must attain mastery over their medium. Even a writer works within the rules of grammar to produce beauty. [...] The logical positivists, who were reconstructing David Hume’s general approach, looked at verifiability as the mark of science. But most of science cannot be verified. It mainly consists of theories that we retain as long as they work but which are often rejected. Science is theoretical rather than proven. Having seen this, Karl Popper proposed falsifiability as the criterion of science. While we cannot prove theories true, he argued, we can at least prove that some are false and this is what demonstrates the superiority of science. The rest is nonsense on his account. The same problems afflict Popper’s account, however. It is just as hard to prove a theory false as it is to prove one true. I am also in sympathy with the early Wittgenstein of the Tractatus Logico-Philosophicus who says that far from being nonsense, the non-sciences are often the most meaningful things in our lives. I am not sure the relationship to truth is really what divides the arts and sciences. [...] The sciences get us what we want. They have plenty of extrinsic value. Medicine enables us to cure illness, for instance, and physics enables us to develop technology. I do not think, in contrast, that we pursue the arts for what they get us. They are usually ends in themselves. But I said this was only a vague distinction. Our greatest scientists are not merely looking to fix practical problems. Newton, Einstein and Darwin seemed primarily to be seeking understanding of the world for its own sake, motivated primarily by a sense of wonder. I would take this again as indicative of the arts and sciences not being as far apart as they are usually depicted. And nor do I see them as being opposed. The best in any field will have a mixture of creativity and discipline and to that extent the arts and sciences are complimentary.
