From jury duty to tax audits, randomness plays a big role. Scientists used quantum physics to build a system that ensures those number draws can’t be gamed.

Populating spreadsheets with placeholder data for visualization, prototyping, or modeling purposes. These functions provide a reliable and efficient way to generate random data, making them ...

[Giorgio]’s random number generator for this project is just a pair of resistors, with an op-amp buffer, amplifier, and current switch to turn analog data into a digital output of random 1s and 0s.
