The shadows lurking in the equations
If you've ever graphed equations, chances are you have only ever graphed equations in what I refer to as "Binary mode" - which draws a line where the equation is EXACTLY equal, and leaves white everywhere else.

Measuring the doppler shift of WWVB during a flight
We advertise 100 kHz as the lower edge of HackRF Pro ’s operating frequency range, but that isn’t a hard limit. While working on the design, I realized that it should work fairly well to pick up longwave time signals such as WWVB , broadcast at 60 kHz from Colorado, USA.

Attention lapses due to sleep deprivation due to flushing fluid from brain
An MIT study reveals what happens in the brain as lapses of attention occur following sleep deprivation. During these lapses, a wave of cerebrospinal fluid flows out of the brain — a process that typically occurs during sleep and helps to wash away waste products that have built up during the day.

A century of reforestation helped keep the eastern US cool (2024)
Throughout the 20th century, as most of the world warmed, the eastern US remained mysteriously cool. Now, scientists think they have an explanation: trees.

Why do some radio towers blink?
One day on my drive home, I saw three towers. One of them had a bunch of blinking white lights, another one had red lights that kind of faded in and out, and the third one, well, it wasn't doing anything. I'm lucky to have a radio engineer for a dad, so Dad: why do some towers blink?

Cancer survival rates are misleading
UPDATE: I submitted a more formal version of this article to the UMAP Journal (Undergraduate Mathematics and Its Applications), which publishes articles that use mathematical modeling for real-world problems, often with a pedagogical or expository angle. A preprint is available on arXiv at…

Interstellar Mission to a Black Hole
If DM could form a BH at the center of a planet, wouldn’t that then collapse the planet into that BH, consuming it? Wouldn’t the same apply to stars, extinguishing them?

Unexpected patterns in historical astronomical observations
Researchers at Nordita at Stockholm University have analyzed flashes of light on astronomical plates from the early 1950s and found statistical connections between the times of these flashes, nuclear weapons tests and reports of unidentified anomalous phenomena (UAP). The results are presented in two studies published…

Lace: A New Kind of Cellular Automata Where Links Matter
This article is about a new kind of simple computational rule ("LACE rules" running on LACE, the Link Automata Computing Engine platform) which, when applied locally on a grid of cells, demonstrates fascinating emergent "artificial life" behavior.
