“They say it's your birthday, it's my birthday too, yeah; They say it's your birthday, we're gonna have a good time; I'm glad it's your birthday, happy birthday to you” from Birthday by Lennon-McCartney Happy 50th Birthday Greg Kinnear! Fifty years. Five decades. Half a century. Whatever way you look at it, in a human lifespan, the fiftieth birthday is a major milestone. A time for celebration, and perhaps more than a little reflection. Undoubtedly, you are spending some time... Read more

Idea Channel - Is The Universe A Computer?
The Hitchhiker’s Guide to the Galaxy is about everything. Life, the Universe, everything. If you’ve read these amazing books, you know the answer is 42, but what’s the question? To find out what the question was, they built a giant computer we call Earth. And though it seems silly, perhaps Douglas Adams was correct, and that not just earth, but the WHOLE UNIVERSE is an incredibility complex computational system, processing the answer to some

As the third week of the short summer session for freshman electromagnetism opens, the minds of young professors everywhere run towards cool polarized light demonstrations. In helping track some of these down, I remembered that there was an awesome experiment involving sodium chlorate in a book titled "Crystals and Crystal Growing" by Alan Holden, Phylis Morrison. It turns out that sodium chlorate crystals pass polarized light at different angles depending on the wavelength of […]

A team of researchers from the Nanoengineering Research Centre (CRNE) and the Department of Electronic Engineering at the Universitat Politècnica de Catalunya—BarcelonaTech (UPC) has found a way to manufacture crystalline silicon materials cheaper and faster. The results of their research have recently been published online in Applied Physics Letters. This thin crystalline silicon wafer production method can be used to fabricate the latest generation of solar cells. Read more »

One of things I like to do, as you know, is to run an order-of-magnitude calculation when I see a claim that seems off, to see if it’s plausible. The future of flight: Shape-shifting engines and body heat power This claim caught my eye Tan Kai Jun, the team leader, envisions cabin seats upholstered with [...]

This is a fascinating shot and there is lot going on. Play it at least three times and watch what happens above the water surface, at the water surface and below the water surface! The explanation over at Fuck Yeah Fluid Dynamics In air, some of the energy of this pressure wave would be dissipated [...]
