For Quality Fusion Surfing, Try Riding The Solar Wind

Researchers at the University of Warwick have found what could be the signal of ideal wave 'surfing' conditions for individual particles within the massive turbulent ocean of the solar wind, a discovery that could give a new insight into just how ...

Wave Field Synthesis Gives Us Flat Loudspeakers With Big Cabinet Sound

Flat-panel televisions are nothing new.   I think even my father has one in his toolshed by now.  But legitimate flat-panel loudspeakers are harder to come by.     There are single-speaker surround sound systems, and those are admirable, but speakers, unli ...

Ferromagnetism In An Atomic Gas

Scientists have observed ferromagnetism in an atomic gas for the first time, addressing the decades-old question of whether gases could show properties similar to a magnet made of iron or nickel. A team observed the ferromagnetic behavior in a gas of lithi ...

Paleomagnetists Create Controversy So They Can Solve It

Did you even know there was a discipline called paleomagnetics?   Probably not.(1)   It isn't easy to find a category on this site to put it in, that's for sure. But a discipline it is and it even has its own controversies, as all science must; n ...

Let's Get Physical (Art)

Science and art aren't mutually exclusive. You can demonstrate scientific concepts artistically, and sometimes even physics can be phun. Take, for example, Sir Isaac's Loft, a feature in the Franklin Institute that "blends art and science in ...

Let's Get Physical (Art) II

Art is many things, but not often enough is it scientific. Fear not, art/science lovers, for Sir Isaac's Loft in the Franklin Institute is here to save the day! I began describing the Loft in my previous article, including impossible human tricks to t ...

The Fourier Transform As Diagonalization

Why is the Fourier Transform so useful both in theoretical and applied science and engineering?  In short, often it is more convenient to solve a problem in Fourier space than the space of the problem's original formulation.  In this case, one prescri ...
