This will never stop blowing my mind. A 12-year sequence of real telescope images of a star 133 lightyears away. And around it, four planets slowly orbiting. Four real exoplanets, each more massive than Jupiter, imaged as they move around their host star.

How do computers calculate complicated trig functions such as tangent? I took a look at Intel's 8087 floating-point chip under the microscope to find out. The chip combines two techniques to evaluate the tan function quickly and accurately: polynomials and an algorithm called CORDIC...
A die photo of the 8087 chip under a microscope shows complex patterns from its transistors and wiring. The middle of the chip holds the microcode ROM, while the bottom half of the chip is the datapath that performs calculations. Zooming in on the datapath shows various functional blocks, which appear as rectangles with different textures. Important functional blocks are labeled: exponent ROM, constant ROM, shifter, adder, registers, and so forth.

#PPOD: 180 years ago today, Johann Gottfried Galle used this telescope to discover Neptune — almost exactly where mathematics predicted it would be. Urbain Le Verrier calculated the location of an unseen planet from its gravitational effects on Uranus. On Sept. 23, 1846, Galle searched for it. 🧪 🔭

In 1980, Intel introduced the 8087 floating-point coprocessor chip. Plugging this chip into your IBM PC made math 100 times faster, good for CAD and spreadsheets. I opened up the chip to reverse-engineer exactly how it does complicated calculations. Let's take a look inside...
The integrated circuit is a black ceramic rectangle with 40 metal pins sticking out, in two rows. (This is known as a DIP, a Dual Inline Package.) It has three rows of text: "D8087-1", a cryptic version label, and then the copyright line with a big lower-case I, INTEL m c 1980 1984. The m and c are in circles for the mask-work symbol and the copyright symbol. The chip has a small semicircular notch on the left side, indicating its orientation. The package consists of two thin ceramic layers, bonded together with a gray substance; the metal pins stick out from this gray substance. The ceramic package is important to me because tapping the gray layer with a chisel will cause the two layers to separate, revealing the silicon die inside. In contrast, most chips are in epoxy packages, which are very difficult to open, usually requiring strong acids.

Given rising interest in the rapidly strengthening El Niño event in the tropical Pacific Ocean, I've created a one-page fact sheet succinctly describing what El Niño is, this year's (remarkable) forecast, and potential impacts from California to global scales. [Thread]
JPEG version of a 1-page Factsheet: El Niño 2026-2027: A Potentially Historic Global Climate Event
By Daniel Swain, PhD | August 2026

There is a banner image depicting projected warming of the Pacific Ocean by early winter.

The content begins:
"What is El Niño?
El Niño is the warm phase of a natural cycle, known as El Niño/Southern Oscillation (ENSO), that occurs roughly every 2-7 years in the tropical Pacific Ocean. During El Niño events, the eastern tropical Pacific Ocean warms to well above typical levels. El Niño directly affects local climate in the countries closest to the unusually warm ocean waters, but can also indirectly influence the climate of distant regions thousands of miles away. During the strongest events, El Niño can profoundly affect climate even on global scales, causing temporary planetary warming and disrupting large-scale precipitation patterns..."

Before semiconductor RAM, most computers used magnetic core memory. This is the 32 KB core stack from the computer on Spacelab, the Space Shuttle's experimental laboratory. Let's take a closer look...
The core stack from the Spacelab computer. This is a stack of six rectangular circuit boards, joined by blue connectors on each end. The cores are visible on the top board. The 294,912 cores are way too small to see; there are eight large reddish-brown squares, each holding a region of cores. 18 reddish and greenish stripes are slightly visible, showing regions for the 18 bits of storage.

Oxford, the longest running continuous weather station in UK history, with temperature observations stretching back to 1815, has preliminarily broken its maximum temperature record for May yesterday by OVER 3ºC with a temperature of 33.7ºC. Unprecedented in its 211-year history.
Spaghetti chart showing Oxford Radcliffe Observatory daily maximum temperatures for every day of the year from 1815 to 2026. 211 years of historical data are shown as very faint grey lines tracing a seasonal cycle from around 5°C in winter to a summer peak of roughly 25–30°C in July and August. A blue smoothed 30-day mean line highlights the average annual temperature cycle. The 2026 line is shown in bold red, running from January through to late May before spiking sharply upward to reach 33.7°C on 26 May, well above the entire historical grey envelope for that time of year. A single dashed red reference line marks the previous May record of 30.6°C set on 29 May 1944. The 2026 reading exceeds this by 3.1°C and, in statistical terms, is the 6th most anomalous maximum temperature in Oxford's 211-year record, ranking as the most anomalous May maximum ever observed and coming within 0.6°C of the all-time June record of 34.3°C set in 1976.
