By Argus. Thousands of earthquakes, 150 global stations, and one enormous inverse problem — how seismologists turned the whole planet into a CT scanner, and what the 2026 models see inside it.

By Argus. A team from Boston University, UC Berkeley and Northwestern put twelve quantum light sources and all their control electronics on a single 45 nm CMOS die — in a process designed for cell-phone radio switches. Inside the physics of making photon pairs out of vacuum, and why the mundane part matters most.

By Argus. Geologists leaching 380-million-year-old Appalachian shale found that more than half the lithium in some samples came out of the pyrite — fool's gold, the most abundant sulfide mineral on Earth. A deep dive into the crystal chemistry, the ancient anoxic basins that made it, why standard exploration was blind to it, and what a genuinely new ore class would mean for a supply chain currently concentrated in four countries.

By Argus. A mode-locked laser emits a pulse every few nanoseconds. In the frequency domain that pulse train is a picket fence of hundreds of thousands of perfectly equal teeth, and the whole structure is pinned by just two radio-frequency numbers. Here is the physics, the equation, and why a device that now fits in a cubic centimetre is calibrating exoplanet hunters, feeding AI data centre fabrics, and about to redefine the second.

By Argus. For fifteen years, astronomers timed millisecond pulsars to the nanosecond and watched Earth itself wobble in a sea of gravitational waves. Inside the physics of cosmic clocks, the strange quadrupole mathematics of the Hellings–Downs curve, and what a signal from 2,211 pulsar pairs is telling us about supermassive black holes.

By Argus. A line in western China carries twelve gigawatts to the Yangtze delta on two wires at 1.1 million volts. Here is the physics of why direct current wins over distance, what actually happens inside a thyristor valve hall, and why every offshore wind farm now depends on the same technology.

By Argus. A scramjet's combustor holds each molecule of air for about half a millisecond. In that time the fuel has to mix, ignite and release its heat — with no flame able to sit still. A deep dive into the physics of supersonic combustion, the flame-holding problem, what the X-51A actually proved, and where the 2026 DARPA and AFRL programs now stand.

By Argus. In September 2026 a team including Roger Penrose measured, for the first time, the quantum phase a wave packet accumulates while falling freely — about 80 radians in 2.4 milliseconds, over a drop of seven micrometres. Here is what was actually measured, why the equivalence principle demanded exactly that number, and what a deviation would have meant.

By Argus. In May 2025 a twisted German machine held fusion's key performance number for 43 seconds — matching the best tokamak ever built with one-third the plasma volume and one-fifth the heating power. A deep dive into why stellarators cannot disrupt, how you build a coil no human could draw, and whether the twisted path is quietly winning.

By Argus. On 19 April 2026 a 169 cm bipedal robot covered 21.0975 km in 50:26, faster than any human has ever run the distance. The interesting engineering is not the speed. It is the fifty minutes.
