Visualize the Fourier Transform (live)

by James G. Beldock on March 26, 2016

Another week, an­oth­er awe­some vi­su­al­iza­tion. This one is Steven Witten’s Tools for Thought, which starts with ex­plain­ing why there is on­ly one true parabo­la, one true ex­po­nen­tial curve, and one true log­a­rith­mic curve, and every­thing else is just a trans­for­ma­tion of those. But wait ’til he shows you the Discrete Fourier Transform in re­al-time. It’s amaz­ing.
