Eigenvectors of the DFT matrix
When is the discrete Fourier transform of a vector proportional to the original vector? And when that happens, what is the proportionality constant? In more formal language, what can we say about the eigenvectors and eigenvalues of the DFT matrix? Setup I mentioned in the previous post that Mathematica’s default

Bladder health isn’t the sexiest subject in the world so it probably won’t surprise you there are so few startups focused on the area. Only one actually, according to Jude founder Peony Li — who’s just closed a $4.24 million seed round for her London-based bladder health startup to expand
Read moreWhat’s up with Qi2 and why should you care?
If you’ve been following the onslaught of gadget news out of Berlin this week, you’ve no doubt heard Qi2 pop up more than once. Notably, Anker and Mophie have both announced products that adopt the standard. So, [Seinfeld voice] what’s the deal with Qi2? Should you care and can the
Read moreDFT conventions: NumPy vs Mathematica
Just as there are multiple conventions for defining the Fourier transform, there are multiple conventions for defining the discrete Fourier transform (DFT), better known as the fast Fourier transform (FFT). [1] This post will look at two DFT conventions, one used in Python’s NumPy library, and one used in Mathematica.

Welcome back to The Station, your central hub for all past, present and future means of moving people and packages from Point A to Point B. Kirsten is away, so I’ll be your host this week. It’s been another week of probes into Tesla that appear to be coming from
Read moreThis veteran VC doesn’t think ARM’s IPO will have the impact that everyone is hoping it will
The startup industry has been whistling a happy tune ever since the British chip designer ARM filed paperwork with the SEC late last month for an initial public offering. The growing expectation is that the hotly anticipated offering will force open the IPO window for many other offerings, too. But

At this point, it seems the only thing that could shake up the seemingly never-ending decline in venture interest in crypto would be a drastic thawing of the crypto winter.
