Harvey moved to Wichita, Kansas, where he was a medical supervisor in a biological testing lab. Over the next 30 years, he sent a few slides to other researchers who wanted to study the brain, but kept the rest of the brain in two glass jars, sometimes in a cider box under a beer cooler.
The story of Einstein's brain was largely forgotten until when a study was finally published. Harvey failed a competency exam in , and his medical license was revoked, Blitz wrote.
Harvey eventually donated the brain to Princeton Hospital, where the brain's journey had begun. Harvey died in Pieces of Einstein's brain are now on display at the Mutter Museum in Philadelphia.
They concluded that it might indicate the neurons had a higher "metabolic need" — that they needed and used more energy and that might explain why Einstein had better thinking abilities and conceptual skills.
However, other researchers have pointed out a few problems with that study , according to Eric H. Chudler, a neuroscientist at the University of Washington. First, for example, the other brains used in the study were all younger than Einstein's brain.
Second, the "experimental group" had only one subject — Einstein. Additional studies are needed to see if these anatomical differences are found in other people. And third, only a small part of Einstein's brain was studied. Another study, published in in the journal Neuroscience Letters, found that Einstein's brain weighed only 1, grams , less than the average adult male brain about 1, g.
Also, Einstein's cerebral cortex was thinner than that of five control brains, but the density of neurons was greater. A study published in in the journal Brain revealed that the Einstein's brain had extra folding in the gray matter, the site of conscious thinking.
In particular, the frontal lobes, regions tied to abstract thought and planning, had unusually elaborate folding, analysis suggested. Scientific work Einstein's legacy in physics is significant. Here are some of his key scientific principles that he pioneered: Theory of special relativity: Einstein showed that physical laws are identical for all observers, as long as they are not under acceleration.
However, the speed of light in a vacuum is always the same, no matter at what speed the observer is travelling. This work led to his realization that space and time are linked into what we now call space-time. So, an event seen by one observer may be seen at a different time by another observer.
Theory of general relativity : This was a reformulation of the law of gravity. In the s, Newton formulated three laws of motion, among them outlining how gravity works between two bodies. The force between them depends on how massive each object is, and how far apart the objects are.
Einstein determined that when thinking about space-time, a massive object is a distortion in space-time like putting a heavy ball on a trampoline. Gravity is exerted when other objects fall into the "well" created by the distortion in space-time, like a marble rolling towards the large ball.
Photoelectric effect: Einstein's work in proposed that light should be thought of as a stream of particles photons instead of just a single wave, as was commonly thought by the time. His work helped explain some curious results scientists saw at the time. The photoelectric effect refers to how electrons are ejected from the surface of a metal due to incident light. The "wave" theory of light suggests that the electrons should be ejected with more energy when the incident light is increased, but experiments showed that the energies are actually independent of the radiation intensity.
He was unsuccessful, but Encyclopedia Britannica suggests that Einstein was ahead of his time because, for example, the strong force in quantum mechanics was better understood in the s and s. Other physicists are still working on this problem. Applications of Einstein's work There are many applications of Einstein's work, but here are some of the bigger ones in astronomy: Gravitational waves : In , the Laser Interferometer Gravitational-Wave Observatory LIGO detected space-time ripples — otherwise known as gravitational waves — that occurred after black holes collided about 1.
LIGO also made an initial detection of gravitational waves in , a century after Einstein predicted these ripples existed. The waves are a facet of Einstein's theory of general relativity.
Mercury's orbit : Mercury is a small planet orbiting close to a very massive object relative to its size — the sun. Its orbit could not be understood until general relativity showed that it's the curvature of space-time that is affecting its motions and changing the orbit.
There is a small chance that over billions of years, Mercury could be ejected from our solar system due to these changes with an even smaller chance that it could collide with Earth. Gravitational lensing : This is a phenomenon by which a massive object like a galaxy cluster or a black hole bends light around it.
Astronomers looking at that region through a telescope can then see objects directly behind the massive object, due to the light being bent. A famous example of this is Einstein's Cross, a quasar in the constellation Pegasus.
Albans, a town about 20 miles north of London. At the age of eleven, Stephen went to St. Albans School and then on to University College, Oxford; his father's old college. Stephen wanted to study Mathematics, although his father would have preferred medicine. Mathematics was not available at University College, so he pursued Physics instead. After three years and not very much work, he was awarded a first class honours degree in Natural Science.
His own private universe expanded when he proposed to his future wife. Stephen Hawking has worked on the basic laws which govern the universe. With Roger Penrose he showed that Einstein's General Theory of Relativity implied space and time would have a beginning in the Big Bang and an end in black holes.
These results indicated that it was necessary to unify General Relativity with Quantum Theory, the other great Scientific development of the first half of the 20th Century.
