I recommend learning about the Fourier Transform, and then peeking at how frequency transformations are used to represent everyday images, like the Cosine Transform used in JPEG. 3 blue 1 brown FFT: https://youtu.be/spUNpyF5

Yeah. That was awful. It occurs to me that anyone lost in the wilderness, due to reliance on incomplete navigation info, is probably not prepared for adventure. I might not have thought to bring a satellite-capable Personal Locator Beacon (

To get a sense of the industry in 1992, browse through BYTE Magazine from that era. There are quality scans available to read online via Archive.org — I find this index to be useful but I’m not sure how up to date it is: https://

The images I've set up for web use are not very large. I don't have a RAW workflow. So maybe I'm missing something. I've found it very challenging to get better compression than optimized JPEG via Squoosh. https:/&

Fish or no fish, my kids were themselves even before the moment they took first breath. I audited some embryology, neuropsychology classes in college. Still seems like a miracle, how the kids arrive... (I won't argue about the magic mo

One last bit, to address the fear factor: Two things about Earth are quite amazing: our atmosphere and Earth's magnetic field. Earth has a solid iron and nickel inner core, surrounded by fluid iron nickel outer core. The motion of the

I want to clarify: I chose "two minutes" as a totally arbitrary example. I think we are all clear about that -- but just "Duration X", for some value. Important to note another class of very violent, energetic event that

If you're reading this, then this Gamma Ray Burst is not going to hurt you. Gamma ray bursts were first detected by satellites that had been designed to watch for nuclear weapons on Earth. They kept reporting super high energy radiati

I have used Flipboard forever, since Google Reader (RSS) was googlized. I agree that it's chock full of clickbait.. I use it in sort of a ritualistic form of reading the news, by sorting the articles into piles. So not only reading som

I think this is a good question, because I had always thought of American Sign Language (ASL) as a transcription of English. But I learned that ASL is a language all of its own, grammar and syntax are not always the same. In college, I lear

Can't hold more than roughly $5000 of real assets and qualify for Medicaid (subsidized healthcare). Keeping that cash in the mattress is a very real option for many people with huge responsibilities (child care) and very little power.

Interesting! But don't use this to run a nuclear reactor. Or airplane. ** :-) Aircraft designs can tolerate a limited amount of deviation around their center of mass. Beyond that, the control surfaces of the aircraft may not provide su

Only 30 years! I trained in a Cessna 152 that was certificated to run on high-octane unleaded auto gas. No modifications, the EAA just demonstrated that it would run fine like that. But my 172 had to use Aviation gasoline. Until now.

"HVM" = High-Volume Manufacturing Used in the comments here... I had to think for a minute to get it. HVM is full production status, as opposed to early risk or testing.
