Scientists at UCSB have been attempting to get the particle using just pencil lead and Scotch tape.

The world spent up to $600B to avert the Y2K computer glitch

Early computer programmers used a two-digit code to record years rather than four. With the switch in the year 2000 from '99 to '00, analysts feared databases might fail and prompt outages and financial catastrophe. To prepare, governments and businesses spent an estimated $300B to $600B to mitigate the glitch.

Limited transparency soon after Chernobyl made it a source of conspiracy theories

Some rumors about the event became perceived as more reliable than the Soviet mass media, which had omitted key information during the early days of uncertainty. The resulting theories included CIA involvement in the disaster, three-headed birds, aliens, and a weaponized earthquake.

The Majorana 1 chip may provide quantum computing using geometry-based qubits

Traditional quantum computers are incredibly fragile, with encoded information easily disrupted and requiring significant error correction systems. Microsoft’s approach involves storing data on a surface, which is more stable, but involves an elusive particle first theorized in 1938.

Pigeons were thought to be the cause of what would be evidence of the Big Bang

In 1964, Arno Penzias and Robert Wilson accidentally detected the CMB while trying to eliminate persistent static from their radio antenna. The pair initially blamed the signal on pigeon droppings inside their antenna—cleaning it didn't help, but it did win them a Nobel Prize.
