How does a fibre-optic cable no thicker than a garden hose carry roughly 99 per cent of intercontinental internet traffic across 13,000 kilometres of ocean floor?

Saving Tips August 9, 2026

The answer is that the cable is barely doing the work. The glass inside it is. Every intercontinental fibre carries…

Every year about 27.7 million tonnes of Saharan dust cross the Atlantic on the trade winds, and NASA’s CALIPSO satellite has traced it fertilising the Amazon with roughly the same quantity of phosphorus the rainforest loses to rivers

Saving Tips July 28, 2026

The Amazon looks like the last place on Earth that would need a delivery of dirt. It is the wettest,…

When a lightning return stroke heats a channel only centimetres wide to roughly 30,000 kelvin, about five times the temperature of the Sun’s visible surface, the air expands so violently that the pressure wave rolls across the ground as thunder

Saving Tips July 28, 2026

A cloud-to-ground lightning return stroke can heat the air inside its narrow channel to roughly 30,000 kelvin, more than five…

In 1947, Harvard’s Mark II ran on roughly 13,000 electromechanical relays, stored numbers across 100 registers, and read instructions from punched paper tape, turning thousands of clicking metal switches into a Navy calculator vulnerable to dust, loose contacts, and one famously misplaced moth

Saving Tips July 27, 2026

Harvard’s Mark II began solving test problems in July 1947 with approximately 13,000 electromechanical relays clicking inside it. The machine…

How did a single computer worm written by a Cornell graduate student in November 1988 crash roughly 6,000 machines and force the internet to invent security?

Saving Tips July 27, 2026

On the evening of 2 November 1988, a Cornell graduate student named Robert Tappan Morris uploaded a small C program…

In 1968, Douglas Engelbart sat before roughly 1,000 computing professionals in San Francisco and demonstrated the mouse, hypertext, video conferencing and shared-screen editing in one 90-minute session, a concentrated glimpse of the interactive computer future later remembered as the Mother of All Demos

Point a phone at a standard QR code taped to a lamppost. The camera can be tilted, the paper can…

Octopuses possess roughly 500 million neurons distributed across their body, with two-thirds located in their arms rather than their central brain, meaning each arm can taste, problem-solve, and react to stimuli independently of whatever the octopus is otherwise paying attention to.

Saving Tips June 10, 2026

A common octopus (Octopus vulgaris) can solve a maze with one arm while another arm, on the far side of…

Every year, roughly two billion new smartphones, laptops, and tablets ship with a key arrangement designed in the 1870s to prevent slender metal arms from colliding inside a machine that has been obsolete for decades, a piece of 19th-century mechanical engineering quietly embedded in the muscle memory of about five billion people.

Saving Tips June 8, 2026

Christopher Latham Sholes patented the layout that now sits under the thumbs of nearly every smartphone owner on Earth in…

When seismic waves from the Chicxulub impact reached what is now North Dakota roughly ten minutes after the asteroid struck, they appear to have triggered a ten-metre standing wave in an inland river that flung fish onto the bank and buried them under glass beads still falling from the sky.

Saving Tips June 5, 2026

Robert DePalma was digging at a ranch in the Hell Creek Formation of southwestern North Dakota, in a place he…
