When a projectile strikes armor without penetrating it, deadly steel discs can still eject from the interior and kill the crew inside. This is spallation — a phenomenon rooted in elastic wave mechanics that plagued WWII tank crews and still challenges modern spacecraft design.

What happens when a knife blade vibrates tens of thousands of times per second? This article traces ultrasonic cutting from the Curie brothers' piezoelectric discovery through industrial applications in electronics, medicine, and food processing — all the way to consumer kitchen knives and DIY 3D-printing tools.

The LK-99 saga of 2023 reignited public excitement about room-temperature superconductivity — and reignited the same misunderstandings that have plagued this field since Georg Bednorz and K. Alex Müller discovered high-temperature superconductivity in 1986. This article traces the history, explains the physics, and untangles the myths.

When a spherical projectile hits kevlar fabric at cosmic velocities, the resulting hole is square — a counterintuitive phenomenon explained by Rakhmatulin waves and the anisotropic mechanics of woven fibers.

From partisan kettles in WWII to Voyager probes 25 billion kilometers from Earth, radioisotope thermoelectric generators have been quietly powering civilization's most remote outposts for decades.

On the night of March 28, 1848, Niagara Falls went almost completely silent. For 30 hours, people walked across the riverbed, danced quadrilles on exposed rocks, and salvaged War of 1812 weapons before the water thundered back.

A deep dive into the history and engineering of railway turntables — from 18th-century mine tracks to Moscow's monorail depot, covering tramways, trolleybuses, and the unique technical artifacts that persist into the modern era.
Science
Most people have never truly unpacked what their dream job actually requires — and most are also blissfully unaware of their own peculiarities. A sharp, funny essay on career choice, self-knowledge, and embracing the specific flavor of madness that makes you employable.
Science
An exploration of the hypothesis that our Universe operates as a giant cellular automaton, drawing on Stephen Wolfram's research to explain speed of light limits, quantum mechanics, dark matter, and other physical phenomena through simple computational rules.
Science
Only 5-6% of plastic actually gets recycled, and the petrochemical industry has known since the 1970s that recycling was economically unviable — yet spent decades and millions promoting the myth.
Science
A comprehensive guide to every type of drill bit you are likely to encounter, from simple spade bits to exotic friction drills and mortising bits. Covers materials, coatings, strengths, weaknesses, and the right tool for every job.
Science
A comprehensive overview of Toxoplasma gondii -- the parasite infecting roughly a third of humanity -- covering its life cycle, dangers during pregnancy, behavioral manipulation of hosts, emerging evidence of male fertility damage, diagnostic methods, and practical prevention advice.
