I found this answer in Math Stack Exchange, but I think it's very sketchy. Does anyone know if this relation exists and a more detailed version? Thx. #fourier #statistics

Haber in this pdf http://scipp.ucsc.edu/~haber/ph215/Gaussian.pdf (see eq. 14) with a nice complex calculus demonstration.

Maddening. I spent far too long today browsing #nerd #stickers for my water bottle. Just on an off chance, I tried "#fourier" and found a really neat one!
The #math is wrong. It shows the sum as being a square wave but the actual series shown would be a sawtooth.

A new CSI style #forensic chemistry paper to start the week. Hand-held analytical instruments such as #Fourier transform infrared and #Raman#spectroscopy are useful for taking samples in the field but lack sensitivity.
We show we can combine the data from FTIR and Raman to classify the method used to make the starting compounds needed to make for the drug #fentanyl.

1.2.3. Sums and products. #Fourier is king but Euler introduced the sigma for summation around 1755.
