[Blindmath] a little off topic, sound of early universe using Mathematica

[Lorne Webber]

this is what I'd refer to as an infographic for the blind. it has nothing to
do with blindness or math access, other than the fact that it's referencing
Mathematica, and a sound file which list members might appreciate, more so
than images. Please ignore if uninterested.

 

University of Washington physicist John Cramer  has devised an audio
re-creation of the big bang and following 7 hundred thousand years using
Mathematica, based on data first gathered by the Wilkinson Microwave
Anisotropy Probe space mission in 2003 mapping the cosmic microwave
background radiation temperature fluctuations, recently updated by the
European Space Agency's Planck satellite mission in March, 2013.

 

"As the universe cooled and expanded, it stretched the wavelengths to create
"more of a bass instrument," Cramer said. The sound gets lower as the
wavelengths are stretched farther, and at first it gets louder but then
gradually fades. The sound was, in fact, so "bass" that he had to boost the
frequency 100 septillion times (that's a 10 followed by 24 more zeroes) just
to get the recordings into a range where they can be heard by humans."

 

The sound files run from 20 seconds to a little longer than 8 minutes. 

Here is the link to professor Cramer's site which has the .wav files, and a
description of how he did the data analysis/transcription in Mathematica.
