In 1964, Douglas Engelbart of the Stanford Research Institute developed the first prototype for a computer pointing device, which was housed in a carved block of North American cherry wood.

(Fox News Digital)

The Svalbard Global Seed Vault stores backup copies of crop seeds from gene banks worldwide in chambers reached by a tunnel running about 130 yards into a frozen mountain and cooled to –18°C. As of 2025 it holds just over 1.3 million seed samples from more than 6,000 plant species and 120+ countries, designed as an "insurance policy" so humanity can replant essential crops if war, disasters or climate change wipe out local collections.

A standard 52-card deck can be arranged in 52! different ways, which works out to about 8.07×10^67 possible orders. That number is so huge that any properly shuffled deck you hold is, for all practical purposes, a sequence of cards that has never appeared before in the entire history of card playing. In fact, 52! is roughly 10^17 times larger than the estimated number of atoms on Earth, so there still wouldn’t be enough atoms for each one to "stand in" for a different card ordering.
