Last week I met Tom Beddard, a physicist turned web developer turned artist (and friendly guy). He creates fractals — those recursive shapes that infinitely repeat at every scale. They’re based on simple math, but they can create some amazing images.
Says Beddard: “I don’t seek any new mathematical insight into the resulting structures, it’s a purely aesthetic pursuit to scratch a creative itch. Part of the fascination with fractal exploration is when … amazing and completely unexpected structures can pop out and surprise you.”
Some of the fractals look like Gothic architecture. Some of them look like alien seed pods. All of them are mesmerizing. You can see lots more on Beddard’s flickr page. You can actually fly through the fractals and see them morphing in these videos. And now, thanks to a new app called Frax that Beddard helped develop, you can make fractals of your very own.
500 kg of Epsom salts are added to 1000 litres of water, creating a 30 cm deep solution, which is heated to 35.5 degrees C (skin temperature).
The temperature of the water means that once you are settled in the tank, it is virtually impossible to distinguish between parts of the body that are in contact with the water, and those that aren’t, in effect “fooling” the brain into believing that the person is floating in mid-air.
I took a lot of pictures of Robin’s Tesla coil last night. I did some longer exposures and then some short exposures to get only a single spark while holding down the shutter to take continuous pictures.
We also stuck a radiometer on the top of it. The radiometer contains low pressure gas which emits light when current flows through it acting similar to a fluorescent light bulb. Here’s how a radiometer normally works.
The pictures I took of the radiometer vary in brightness because I adjusted the exposure on each picture. When we were watching it was a fairly consistent brightness.
