Albert Einstein developed his theory of special relativity in 1905, and then mentally mapped out his theory of general relativity between 1907 and 1915. For years to come, the rest of the world would try to catch up with Einstein, trying to understand the gist, let alone the full implications, of his groundbreaking ideas.
Above, you can watch one such attempt. Produced by Max and David Fleischer, best known for their Betty Boop and Superman cartoons, The Einstein Theory of Relativity used the power of animation to explain relativity to a broad, non-scientific audience in 1923. One of the first educational science films ever made, the silent animated film was created with the assistance of science journalist Garrett P. Serviss and other experts who had a handle on Einstein’s theories. According to a biography of Max Fleischer, the film was “an out-and-out success.” “The critics and the public applauded it. And Einstein did too, apparently deeming it an “excellent attempt to illustrate an abstract subject.”

Professor Einstein was surprised tonight into loud and long laughter.
Hollywood demonstrated its principles of “relativity,” how it makes things seem what they are not, by use of a dilapidated motor car.
At the First National studio, German technicians persuaded Professor Einstein to change his mind about not being photographed and photographed him in the old car with Frau Elsa, his wife. He cannot drive a car.
Tonight the German technicians brought the film to the Einstein bungalow. The lights went out.
Then the ancient automobile appeared on the screen with Einstein at the wheel, driving Frau Elsa on a sight-seeing tour.
Down Broadway, Los Angeles they drove, then to the beaches. Suddenly the car rose like an airplane, and as Einstein took one hand from the wheel to point out the scenery, the Rocky Mountains appeared below. Then the car landed on familiar soil and the drive continued through Germany.
It was just a Hollywood trick of double exposure and a thrilling comedy, but not for the public. The master film was destroyed, and the only copy was given to the Einsteins.
That one surviving copy of the film eventually ended up in the archives at Lincoln Center, where it sat unnoticed for decades, until Becca Bender, an archivist, stumbled up on it last year. And fortunately now we can all enjoy that light moment shot so long ago.

First presented in the early 1960s at Caltech by the Nobel Prize-winning physicist Richard Feynman, the lectures were eventually turned into a book by Feynman, Robert B. Leighton, and Matthew Sands. The text went on to become arguably the most popular physics book ever written, selling more than 1.5 million copies in English, and getting translated into a dozen languages.
Schrödinger’s Cat is one of the more famous thought experiments in modern physics, created by Austrian physicist Erwin Schrödinger back in 1935. The Telegraph summarizes the gist of the experiment as follows:
In the hypothetical experiment … a cat is placed in a sealed box along with a radioactive sample, a Geiger counter and a bottle of poison.
If the Geiger counter detects that the radioactive material has decayed, it will trigger the smashing of the bottle of poison and the cat will be killed.
The experiment was designed to illustrate the flaws of the ‘Copenhagen interpretation’ of quantum mechanics, which states that a particle exists in all states at once until observed.
If the Copenhagen interpretation suggests the radioactive material can have simultaneously decayed and not decayed in the sealed environment, then it follows the cat too is both alive and dead until the box is opened.

Here’s an extraordinary recording of Albert Einstein from the fall of 1941, reading a full-length essay in English:
The essay is called “The Common Language of Science.” It was recorded in September of 1941 as a radio address to the British Association for the Advancement of Science. The recording was apparently made in America, as Einstein never returned to Europe after emigrating from Germany in 1933.
Einstein begins by sketching a brief outline of the development of language, before exploring the connection between language and thinking. “Is there no thinking without the use of language,” asks Einstein, “namely in concepts and concept-combinations for which words need not necessarily come to mind? Has not every one of us struggled for words although the connection between ‘things’ was already clear?”
Despite this evident separation between language and thinking, Einstein quickly points out that it would be a gross mistake to conclude that the two are entirely independent. In fact, he says, “the mental development of the individual and his way of forming concepts depend to a high degree upon language.” Thus a shared language implies a shared mentality. For this reason Einstein sees the language of science, with its mathematical signs, as having a truly global role in influencing the way people think:
The supernational character of scientific concepts and scientific language is due to the fact that they have been set up by the best brains of all countries and all times. In solitude, and yet in cooperative effort as regards the final effect, they created the spiritual tools for the technical revolutions which have transformed the life of mankind in the last centuries. Their system of concepts has served as a guide in the bewildering chaos of perceptions so that we learned to grasp general truths from particular observations.
Einstein concludes with a cautionary reminder that the scientific method is only a means toward an end, and that the welfare of humanity depends ultimately on shared goals.
Perfection of means and confusion of goals seem–in my opinion–to characterize our age. If we desire sincerely and passionately for the safety, the welfare, and the free development of the talents of all men, we shall not be in want of the means to approach such a state. Even if only a small part of mankind strives for such goals, their superiority will prove itself in the long run.
The immediate context of Einstein’s message was, of course, World War II. The air force of Einstein’s native country had only recently called off its bombing campaign against England. A year before, London weathered 57 straight nights of bombing by the Luftwaffe. Einstein had always felt a deep sense of gratitude to the British scientific community for its efforts during World War I to test the General Theory of Relativity, despite the fact that its author was from an enemy nation.
“The Common Language of Science” was first published a year after the radio address, in Advancement of Science 2, no. 5. It is currently available in the Einstein anthologies Out of My Later Years and Ideas and Opinions.

Long before humanity had paper to write on, we had papyrus. Made of the pith of the wetland plant Cyperus papyrus and first used in ancient Egypt, it made for quite a step up in terms of convenience from, say, the stone tablet. And not only could you write on it, you could rewrite on it. In that sense it was less the paper of its day than the first-generation video tape: given the expense of the stuff, it often made sense to erase the content already written on a piece of papyrus in order to record something more timely. But you couldn’t completely obliterate the previous layers of text, a fact that has long held out promise to scholars of ancient history looking to expand their field of primary sources.
Originally composed by Galen of Pergamon, “an influential physician and a philosopher of early Western medicine,” the work made its way into the 6th-century Islamic world through a translation into a language between Greek and Arabic called Syriac.
Alas, “despite the physician’s fame, the most complete surviving version of the translated manuscript was erased and written over with hymns in the 11th century – a common practice at the time.” Palimpsest, the word coined to describe such texts written, erased, and written over on pre-paper materials like papyrus and parchment, has long since had a place in the lexicon as a metaphor for anything long-historied, multi-layered, and fully understandable only with effort. The Stanford team’s effort involved a technique called X‑ray fluorescence (XRF), whose rays “knock out electrons close to the nuclei of metal atoms, and these holes are filled with outer electrons resulting in characteristic X‑ray fluorescence that can be picked up by a sensitive detector.”
Those rays “penetrate through layers of text and calcium, and the hidden Galen text and the newer religious text fluoresce in slightly different ways because their inks contain different combinations of metals such as iron, zinc, mercury and copper.” Each of the leather-bound book’s 26 pages takes ten hours to scan, and the enormous amounts of new data collected will presumably occupy a variety of experts on the ancient world — on the Greek and Islamic civilizations, on their languages, on their medicine — for much longer thereafter. But you do have to wonder: what kind of unimaginably advanced technology will our descendants a millennium and a half years from now be using to read all of the stuff we thought we’d erased?

Earlier today, they laid Stephen Hawking to rest in a private funeral held at University Church of St. Mary the Great in Cambridge, England. Although the funeral itself was attended by only 500 guests, the streets of Cambridge swelled with onlookers who broke into applause as the coffin holding the physicist made its way into the church, leaving us with some proof that there’s still something right in a world tilting toward the wrong, that we can still appreciate someone who overcame so much, and left us with even more.
