When the sun reaches the right angle in the sky, a beam of light will ricochet along the mirrors, strike a diffuser, and illuminate the great chamber where the vampires sleep.

Twenty-five years ago, physicist Robert Lang worked at NASA, where he researched lasers. He has also garnered 46 patents on optoelectronics and even wrote a Ph.D. thesis called "Semiconductor Lasers: New Geometries and Spectral Properties." But in 2001, Lang left his job in order to pursue a passion he's had since childhood: origami. In the origami world, Lang is now a legend, and it's not just his eye-catching, intricate designs that have taken the craft by storm. Some of his work has helped pioneer new ways of applying origami principles to complex real-world engineering problems.

The saxophone is one of the most popular instruments, so why is it not a regular in the orchestra? Contrary to what some people say, it's not because the sax "doesn't blend" - in fact, it was designed with blending in mind, and blends fantastically well with almost any instrument. The real reasons are largely historical to do with the cartel-like world of Parisian instrument manufacturers in the 19th Century, and the effect this had on the instrument's perception over the next 100 years.

There are some stories that just seem right, some things that make perfect sense and don't require further explanation. The story of pitch inflation is not one of those.

If you’ve ever seen an orchestra perform you’ve probably had a difficult time looking away from the person dead center on the stage – the conductor. It’s hard to miss someone as they swing their arms around pointing at the musicians that seem to be focused instead on their music stands. So what exactly is the conductor doing?
