10 Strange Things About The Universe Space The universe can be a very strange place. While groundbreaking ideas such as quantum theory, relativity and even the Earth going around the Sun might be commonly accepted now, science still continues to show that the universe contains things you might find it difficult to believe, and even more difficult to get your head around. Theoretically, the lowest temperature that can be achieved is absolute zero, exactly ?

Science, Optics and You Online Activities for Students The following activities are provided to help you investigate light, optics, and color. They were written by educators with input from scientists, researchers, students, and teachers. Energy & Machines Activities and Games Free Downloads Physical Science Sorry this category is so small. I don't often get stuck in situations where I have to generate physical science resources. (My inventions always come about as the result of finding myself in a teaching situation for which I can't find adequate resources.) Energy

Simple Mechanics Cams The basic principle of the cam is to turn a circular motion into a linear one. This is referred to as reciprocating movement. In it's simplest form you turn a handle to make something move up and down. The cam-follower is connected to, and part off, a shaft known as the Push-Rod.

Black hole binge could test general relativity - space - 03 May 2013 CRACKS in Einstein's theory of relativity could be evident at the heart of our very own galaxy. If new calculations are correct, the enormous black hole that sits at the core of the Milky Way should have Saturn-like rings that offer a safe haven from its irresistible gravitational pull. Einstein came out with his theory of general relativity in 1916.

Practical Physics This website is for teachers of physics in schools and colleges. It is a collection of experiments that demonstrate a wide range of physical concepts and processes. Some of the experiments can be used as starting-points for investigations or for enhancement activities. Five-Minute Film Festival: The Science of Sports Editor's Note: VideoAmy here ... I'm excited to have Edutopia's new Web Video Strategy Coordinator, Keyana Stevens, guest curating today's Five-Minute Film Festival. You may be seeing more of Keyana in this space moving forward, I'm sure you'll love her picks as much as I do! Math, Physics, and Engineering Applets Oscillations and Waves Acoustics Signal Processing Electricity and Magnetism: Statics Physicists chip away at mystery of antimatter imbalance (PhysOrg.com) -- Why there is stuff in the universe—more properly, why there is an imbalance between matter and antimatter—is one of the long-standing mysteries of cosmology. A team of researchers working at the National Institute of Standards and Technology has just concluded a 10-year-long study of the fate of neutrons in an attempt to resolve the question, the most sensitive such measurement ever made. The universe, they concede, has managed to keep its secret for the time being, but they’ve succeeded in significantly narrowing the number of possible answers. Though the word itself evokes science fiction, antimatter is an ordinary—if highly uncommon—material that cosmologists believe once made up almost exactly half of the substance of the universe. When particles and their antiparticles come into contact, they instantly annihilate one another in a flash of light. “The question is, why was there an excess of one over the other in the first place?”
