"Relativity is just science's way of flip-flopping. Space or time, mass or energy? Which is it, pick a side [...] And I'm sorry, E equals m c squared? C does not stand for the speed of light, c is for cookie."
Occam's (or Ockham's) razor is a principle attributed to the 14th century logician and Franciscan friar; William of Occam. Ockham was the village in the English county of Surrey where he was born.
Max Tegmark (born 5 May 1967) is a Swedish-American cosmologist. Tegmark is an Associate Professor at the Massachusetts Institute of Technology where he belongs to the scientific directorate of the Foundational Questions Institute. Currently, he also teaches a relativity class (8.033) to undergraduates at MIT.
From the article: Since the early 20th century physicists have known that light carries momentum, but the way this momentum changes as light passes through different media is much less clear. Two rival theories of the time predicted precisely the opposite effect for light incident on a dielectric: one suggesting it pushes the surface in the direction light is traveling; the other suggesting it drags the surface backwards towards the source of light. After 100 years of conflicting experimental results, a team of experimentalists from China believe they have finally found a resolution
Founded in 1887 Zeitschrift für Physikalische Chemie covers the main developments in physical chemistry with emphasis on experimental research. It represents a combination of reaction kinetics and spectroscopy, surface research and electrochemistry, thermodynamics and structure analysis of matter in its various conditions.

The NOVA mini-series The Elegant Universe, watch all three one hour episodes here, divided into chapters, available in the QuickTime or RealPlayer plug-ins.
This site provides a free physics textbook that tells the story of how it became possible, after 2500 years of exploration, to answer such questions. The book is written for the curious: it is entertaining, surprising and challenging on every page.
an online academic journal accepting publications on any subject. Philica takes a completely revolutionary approach to the publishing and reviewing of academic research. The instant, open-access Journal of Everything
provides direct links to over 7000 scholarly periodicals which allow some or all of their online content to be viewed by ANYONE with Internet access for free
by Richard Walters ("For the People" magazine) "Physicist Bruce DePalma has a 100 kilowatt generator, which he invented, sitting in his garage. It could power his whole house, but if he turns it on, the government may confiscate it. "
an open source, high performance library for simulating rigid body dynamics. It is fully featured, stable, mature and platform independent with an easy to use C/C++ API. It has advanced joint types and integrated collision detection with friction.
An anemometer looks like a weather vane, but instead of measuring which direction the wind is blowing with pointers, it has four cups so that it can more accurately measure wind speed. Each cup is attached to the end of a horizontal arm, each of which is mounted on a central axis, like spokes on a wheel. When wind pushes into the cups, they rotate the axis. The faster the wind, the faster the cups spin the axis.
What kind of power would you need to overcome this obstacle? Why is this such a difficult thing to do? Well, a ninja trying to climb this ladder not only has to do something like a pull-up (no easy feat) he has to end the pull-up with enough vertical velocity so that he can be “airborne” long enough for him to move the bar to the next level. Really, this is the part that makes it tough and this is the part that I want to calculate the power for. Let’s go.
Stereoscopic visualization is seldom used in Astrophysical publications and presentations compared to other scientific fields, e.g., Biochemistry, where it has been recognized as a valuable tool for decades.
