Are we alone?

March 10, 2023

Jupiter’s second Galilean Moon, Europa, with its interior ocean, predominantly crater-less surface, and crisscrosses of cracks and ridges spanning entire hemispheres, makes it one of the most fascinating planetary bodies ever observed. These unique geologic features are possibly indicative of liquid water traveling to the surface from its deep ocean, making Europa a hot spot for the exploration and study of life beyond Earth, also known as astrobiology.

My mind boggles. We haven’t quite created intelligence that exceeds our own, but we appear to be close (for better or for worse I can’t really say.) But I’ve been occasionally suffering from vertigo thinking: I may live to see it. The thing that has fascinated us for so long— The thing that I’ve read and seen in fiction my entire life— I may yet live to see that.

But when we find life somewhere besides upon our precious blue marble… I’m gonna lose my mind. Life on (in?) Europa seems bonkers, right? There’d be absolutely no light in that ocean… and yet. We find the bottom of our own tiny (compared to Europa’s) oceans teaming with life around sources of heat. That sounds exactly like Europa.

Also, you should totally go watch the film, Europa Report . . .

That’s a moiré

“You don’t need [machine learning,]” Bryan said. “What you need is inverse Fast Fourier Transform.”

I stumbled over a blog post, containing a pull-quote where someone mentioned inverse Fast Fourier Transform. (A mathematician named Fourier invented a fast way to do a certain sort of transformation that comes up a lot in science; It’s called a Fast Fourier Transform. There’s also a way to undo that transformation, called “the inverse”. Thus, Fast Fourier Transformations (FFT) and inverse FFT. Well, FFT/IFFT is the first thing I can recall that I could not understand. It was shocking. Every other thing I’d ever encountered was easy. But there I was, 20-some-years-old, in graduate school, and I encountered something that was beyond me. I think I had it sorted about 6 times and every time, the next morning, upon waking, it had fallen out of my head. Holy inappropriately long parentheticals, Batman!)

Anyway. Blog post. IFFTs. Time machine to the early 90s. Emotional vertigo.

…and then I clicked thru to the magnificent post which is brilliant. And then I realized the by-line was, “Shift Happens.” o_O This entire thing. I’m in nerd heaven.
