The Chemical History of a Candle

Absolutely beautiful and stunning series. Required viewing of all that breath.
Michael Faraday’s The Chemical History of a Candle retold by Bill Hammack.

Solar Time

, , on October 6, 2015

Solar time uses the position of the sun in the sky to mark and coordinate events. Time is complicated (my definition is in the preceding sentence). Light cones are a new breakfast cereal. Can you name the controversial seven fundamental base units?
This neat figure shows the difference between solar time and standard time. When I’m in charge of time keeping some day I assure you a sundial and length of daylight will be involved.

Space Wonder

, , , , on March 22, 2015

Roger Dean creates wonderful science fiction scenery.
Recently read Against the Fall of Night by Arthur C Clarke, which is bursting with interesting ideas. Some more for thought:
Outer Space – I bet you can figure out with decent certainty your location across the entire universe just from sampling the nearest bit of space.
Heliosphere – Similar to the above; every drop of space from many AUs away to the nearest lake has a unique composition.
Deep Space Network – at the very least a catchy name
Voyager 1’s Family Portrait
New Horizons – Almost to Pluto!
Thermoelectric Effect – not directly related, but super cool

What is a Fourier Transform?

, , on October 27, 2011

A mathematical method of converting a set of data (represented as any function) to the sum of its wave components.
Basically, this is a result of the idea that a function can be exactly recreated using only combinations of sin and cosin functions of various amplitude, phase, and frequency. The trick is that most transforms require a lot of computing to tease out every wave component.
