A phone knows which way is up because a silicon chip smaller than a grain of rice contains tiny cantilever beams that physically bend under gravity, and the circuit measures how far they flex in three axes thousands of times a secondSeptember 7, 2026
At 3 gigahertz, a processor has only a third of a nanosecond between clock ticks, enough time for light to travel about 10 centimetres in vacuum before real interconnects, logic gates and capacitance shrink the distance a signal can cross on the chip Saving Tips July 24, 2026 A processor running at 3 gigahertz gets one clock cycle every 333 picoseconds, roughly a third of a nanosecond. In…
The Voyager Golden Record has a small sample of uranium electroplated onto its cover, put there so that whoever finds it can measure how far the metal has decayed and work out how long the record has been drifting, a built-in clock for a message engineered to last around a billion years. Saving Tips May 28, 2026 Two identical records left Earth in 1977, one bolted to each Voyager spacecraft. The disc is the part most people…
