Red, green and blue became the primary colours on every screen because the human retina carries just three types of cone cells — the pixels aren’t matching the light, they’re matching your eyes

In 1911, the Dutch physicist Heike Kamerlingh Onnes cooled a thread of mercury to 4.2 kelvin in a bath of liquid helium and its electrical resistance vanished completely, and a current set circulating in a superconducting loop like that will still be flowing years later, indistinguishable from the day it began

When Adobe announced Flash’s end-of-life in July 2017, it closed a technology that had once run on 99 per cent of desktops — and took with it an estimated four million animations, games and interactive works now preserved only by an amateur archive called Flashpoint

The GPS satellites orbiting 20,200 kilometres overhead run their clocks about 38 microseconds faster per day than clocks on the ground — without Einstein’s relativity correcting for it, GPS would drift by roughly 10 kilometres every 24 hours

Every time you book a flight or check a hotel room, your request is routed through a green-screen mainframe system that traces back to the 1960s — and the entire multi-billion-dollar travel industry still relies on this ancient digital foundation because replacing it would be enormously expensive, dangerous, and slow

Your phone does not actually know how much battery it has left; a fuel-gauge chip estimates the percentage from current, voltage, temperature, and a model of the cell, with a late correction sometimes turning 15 percent into 3 percent in less than a minute

Wi-Fi doesn’t actually slow down when a café gets crowded — the signal is fine, but every device has to wait its turn to speak on the same frequency, and the polite queuing is what you feel as lag

Voyager 1 is still transmitting from more than 25 billion kilometres away, powered by less than 250 watts of decaying plutonium — a signal that now takes over 23 hours to reach Earth, carried by a radio no stronger than a refrigerator lightbulb

When you delete a file, the data itself stays on the disk untouched — the operating system only removes the pointer to it, which is why forensic tools can recover files months after they seem to have vanished
