Science Friday: How Einstein proved E=mc² March 30, 2012, 10:27 AM — If you've ever wondered how Einstein arrived at his famous calculation, YouTuber "minutephysics" has you covered. In about two minutes, here's how he did it: Physics Flash Animations - StumbleUpon We have been increasingly using Flash animations for illustrating Physics content. This page provides access to those animations which may be of general interest. The animations will appear in a separate window.

Usenet Physics FAQ Version Date: February 2018 This list of answers to frequently asked questions in physics was created by Scott Chase in 1992. Its purpose was to provide good answers to questions that had been discussed often in the sci.physics and related Internet news groups.

'Schrödinger's hat' could spy on quantum particles An international team of physicists has proposed a new device that could detect the presence of waves or particles while barely disturbing them. Called a "Schrödinger's hat", the device has not yet been built in the lab but the team believes that it could someday be used as a new type of sensor for quantum-information systems. In the microscopic world of quantum mechanics, direct observation of the property of a particle – the position of an electron, for example – causes the collapse of the particle's wavefunction. The result is that the particle that you set out to measure has been changed in a significant way.

The Law of Attraction - StumbleUpon In this post I want to describe what the Law of Attraction is, how you can use it to attract beautiful things to your life, and then attempt to explain how it works. If you have never heard about the law of attraction before, it may seem like a bizarre concept at first, but don’t let that prevent you from learning what could easily be one of the most important things you can learn in your life. To put it in simple words, the Law of Attraction states that your intentions become your reality, therefore the more you think about something, the more chances you have to bring it to reality. The Law of Attraction states that all the power comes from the universe, because at the lowest level, we are all made of the same thing: energy.

The Sliding Rocks of Racetrack Playa Mystery One of the most interesting mysteries of Death Valley National Park is the sliding rocks at Racetrack Playa (a playa is a dry lake bed). These rocks can be found on the floor of the playa with long trails behind them. Somehow these rocks slide across the playa, cutting a furrow in the sediment as they move. 8 shocking things we learned from Stephen Hawking's book From the idea that our universe is one among many, to the revelation that mathematician Pythagoras didn't actually invent the Pythagorean theorem, here are eight shocking things we learned from reading physicist Stephen Hawking's new book, "The Grand Design," written with fellow physicist Leonard Mlodinow of Caltech. The book, covering major questions about the nature and origin of the universe, was released Sept. 7 by its publisher, Bantam. 1. The past is possibility According to Hawking and Mlodinow, one consequence of the theory of quantum mechanics is that events in the past that were not directly observed did not happen in a definite way. Instead they happened in all possible ways. This is related to the probabilistic nature of matter and energy revealed by quantum mechanics: Unless forced to choose a particular state by direct interference from an outside observation, things will hover in a state of uncertainty.

Psilocybin, the Drug in Magic Mushrooms, Lifts Mood and Increases... The psychedelic drug in magic mushrooms may have lasting medical and spiritual benefits, according to new research from Johns Hopkins School of Medicine. The mushroom-derived hallucinogen, called psilocybin, is known to trigger transformative spiritual states, but at high doses it can also result in “bad trips” marked by terror and panic. The trick is to get the dose just right, which the Johns Hopkins researchers report having accomplished. In their study, the Hopkins scientists were able to reliably induce transcendental experiences in volunteers, which offered long-lasting psychological growth and helped people find peace in their lives — without the negative effects. (PHOTOS: Inside Colorado’s Marijuana Industry) “The important point here is that we found the sweet spot where we can optimize the positive persistent effects and avoid some of the fear and anxiety that can occur and can be quite disruptive,” says lead author Roland Griffiths, professor of behavioral biology at Hopkins.

Stunning Infographics and Data Visualization Feb 02 2010 Information graphics, or infographics, are visual representations of information, data or knowledge. The graphics are used where complex information needs to be explained quickly and clearly, such as on signs and maps and in journalism, technical writing and education. Today, infographics surround us in the media, in published works both mainstream and scientific and in road signs and manuals. They illustrate information that would be unwieldy in text form and act as a visual shorthand for everyday concepts, such as “Stop” and “Go.” Astronomy Interactives This site provides ranking tasks for teaching introductory astronomy. Pencil-and-paper versions as well as computer-based versions are available grouped by topic. New materials will be added as the computer-based versions are completed.

Buddhism and the Brain & SEEDMAGAZINE.COM - StumbleUpon Credit: Flickr user eschipul Over the last few decades many Buddhists and quite a few neuroscientists have examined Buddhism and neuroscience, with both groups reporting overlap. I’m sorry to say I have been privately dismissive. One hears this sort of thing all the time, from any religion, and I was sure in this case it would break down upon closer scrutiny. When a scientific discovery seems to support any religious teaching, you can expect members of that religion to become strict empiricists, telling themselves and the world that their belief is grounded in reality.
