Einstein's Pathway to Special Relativity Back to main course page John D. Norton Department of History and Philosophy of Science University of Pittsburgh Background reading: J. Schwartz and M. We have now reviewed the developments in the physics of moving bodies, of light, of electricity and magnetism that brought the physics that Einstein found when he began to think about ether, electricity, magnetism and motion. It was pondering these developments that led Einstein to discover the special theory of relativity in 1905. The story of Einstein's discovery of special relativity has exercised an almost irresistible fascination on many, in spite of the dearth of sources. Chasing a beam of light Einstein in high school Writing a half century later in 1946 in his Autobiographical Notes, Einstein recounted a thought experiment conducted while he was a 16 year old student in 1896 that marked his first steps towards special relativity. "...a paradox upon which I had already hit at the age of sixteen: The basic thought is clear.
Albert Einstein Albert Einstein (/ˈælbərt ˈaɪnʃtaɪn/; German: [ˈalbɐrt ˈaɪnʃtaɪn]; 14 March 1879 – 18 April 1955) was a German-born theoretical physicist. Einstein's work is also known for its influence on the philosophy of science.[4][5] He developed the general theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics).[3][6]:274 Einstein is best known in popular culture for his mass–energy equivalence formula E = mc2 (which has been dubbed "the world's most famous equation").[7] He received the 1921 Nobel Prize in Physics for his "services to theoretical physics", in particular his discovery of the law of the photoelectric effect, a pivotal step in the evolution of quantum theory.[8] Near the beginning of his career, Einstein thought that Newtonian mechanics was no longer enough to reconcile the laws of classical mechanics with the laws of the electromagnetic field. This led to the development of his special theory of relativity. Life Early life and education Death

Bomb Facts: How Nuclear Weapons are Made Bomb Facts: How Nuclear Weapons are Made A. Plutonium The world's first nuclear explosion was achieved with plutonium, a man-made element produced in nuclear reactors. (a) Plutonium needed to make a bomb: - 4 kilograms: Weight of a solid sphere of plutonium just large enough to achieve a critical mass with a beryllium reflector. (b) Plutonium generated by various reactors: (c) Estimated amount of heavy water needed for a small reactor used to make nuclear weapons: - 19 metric tons: India's 40 megawatt (thermal) Cirus reactor. - More than 36 metric tons: Israel's more than 100 megawatt (thermal) Dimona reactor. - 78 metric tons: India's 100 megawatt (thermal) Dhruva reactor. B. The world's second nuclear explosion was achieved with uranium-235. (a) Uranium-235 needed to make a bomb: - 15 kilograms: Weight of a solid sphere of 100 percent uranium-235 just large enough to achieve a critical mass with a beryllium reflector. (b) Various methods used to enrich uranium: (b) Gaseous Diffusion France
image What Is Michael Burry Doing Today? ‘The Big Short’ Character Is Still Weary Of The Financial Market Adam McKay's dramedy about the 2008 financial crisis, The Big Short, is drawing rave reviews and plenty of Oscar buzz, with some even saying the movie makes the confusing housing market meltdown more accessible than it's ever been before. The film's cast is tremendous, with Brad Pitt, Steve Carrell, and Ryan Gosling all playing fictional characters who are based on people who actually saw what was happening in the market. But the most intriguing character of all also happens to be a real person: Dr. Michael Burry, portrayed in the film by Christian Bale. Burry is still involved in the financial sector, and he's still making predictions about what could go wrong in the economy. But after a few years of laying low, Burry decided to once again become a hedge fund manager. In a Dec. 28, 2015 interview with New York Magazine, Burry outlines the problems he still sees in the financial system — and he doesn't think the preventative measures put in place by the government are helping matters.
Do Try This At Home Scientific experiments do not need to happen in fancy laboratories. Exploring science can happen at home using inexpensive supplies. Oobleck Oobleck is a non-Newtonian fluid that behaves unlike other fluids. For this experiment, you will need: 1 part water 2 parts cornstarch Drops of food coloring (there are a few options with this) Combine ingredients and stir. Oobleck is nontoxic, but does get messy. Precipitation in a Jar: Exploring precipitation at home is quite easy. 200 ml (1 cup) Hot, but not boiling, water Tall glass jar Glass plate Ice cubes Pour the hot water into the clear glass jar and immediately cover with the plate. DNA Extraction DNA can be extracted and examined quite easily. To begin, you will need to choose the source of DNA. Add the plant material, salt, and water to the blender. Unpoppable bubbles Industrial strength bubbles that resist popping are easy to make. Slowly stir the ingredients together in the bowl, as to not form bubbles. Glow in the Dark Bubbles
Michael Jackson American singer (1958–2009) Jackson is one of the best-selling music artists of all time, with estimated sales of over 400 million records worldwide.[nb 2] He had 13 Billboard Hot 100 number-one singles (fourth highest of any artist in the Hot 100 era) and was the first artist to have a top-ten single on the Billboard Hot 100 in five different decades. His honors include 15 Grammy Awards, six Brit Awards, a Golden Globe Award, and 39 Guinness World Records, including the "Most Successful Entertainer of All Time".

How the Science of Swarms Can Help Us Fight Cancer and Predict the Future | Science The first thing to hit Iain Couzin when he walked into the Oxford lab where he kept his locusts was the smell, like a stale barn full of old hay. The second, third, and fourth things to hit him were locusts. The insects frequently escaped their cages and careened into the faces of scientists and lab techs. The room was hot and humid, and the constant commotion of 20,000 bugs produced a miasma of aerosolized insect exoskeleton. In the mid-2000s that lab was, however, one of the only places on earth to do the kind of science Couzin wanted. Couzin would put groups of up to 120 juveniles into a sombrero-shaped arena he called the locust accelerator, letting them walk in circles around the rim for eight hours a day while an overhead camera filmed their movements and software mapped their positions and orientations. That’s what happens in nature, but no one had ever induced these shifts in the lab—at least not in animals. The answer turned out to be quite grisly. Today it’s not working.
How To Fathom Pi: Amazing Visual Illustrations Distribution of the first 123,201 digits of π mapped onto a red-yellow-blue Brewer palette and placed as circles on an Archimedean spiral by Martin Krzywinski Pi is, quite possibly, the most famous number known to man.* This fact is a little bit ironic, as we don’t actually have a number for pi. Well, not a complete number anyways, because pi never ends. If you try to pin it down to the decimal, you can’t do it—the decimal representation goes on endlessly, and it never settles into a repeating patters. Hence, all the fame. If you are unfamiliar with this number, pi is the mathematical constant that represents the ratio of a circle’s circumference to its diameter, and it is typically written as 3.14159 . However, (despite some minor set backs) the quest to understand pi continues. Recently, Cristian Ilies Vasile created an amazing way to visualize pi. This visual representation was created by a 41 year old individual who suffered brain damage after being attacked by muggers.
