Hacking

What does it mean to be a hacker?  If you’re like me, a physics graduate student or any other person struggling to meet your programming demands and expand your programming skills, you might agree with my opinion that it just … Continue reading

Some notes on reconstruction algorithms and “choosing the right parameter”

First, somewhat unrelated, here are some Acrobat Reader shortcuts.  I’m especially excited about Alt + <– and Alt + –> to go backward or forward a “view”.  So for example, in a paper with internal hyperlinks to the citations as … Continue reading

Circulant Matrices, Gabor Frames, Weyl-Heisenberg groups, and the Fourier Transformm

In signal processing the marks of great physicist-mathematicians of the early 20th century and beyond are everywhere.  Apparently when Gabor authored his seminal paper (cited by 4087 according to google scholar), he was building on the foundations of laid by … Continue reading
