Nice explanation, especially why the Fourier transform F(u) of a real valued function f(t) is complex.

Reason: F(u) encodes as a complex number

- the magnitude of each sinoid (real part)
- and the phase shift (imaginery part)

Very nice drawings + explanations, but the speaker speaks without any breaks!
