A prediction market was more accurate than most polls about the 2024 US presidential election

What compels an audience shifts over time, meaning yesterday's popular speeches might not go over the same way if delivered today.

Additionally, US political candidates typically promote themselves in their speeches, an approach initially considered vulgar in Australia and Britain.

The first algorithmic random number generator was developed in 1946

Although previous methods of randomness involved physical tools with limited outcomes, such as dice, or relied on chaotic variables for number generation, such as electronic noise, John Von Neumann's middle-square method turned the problem into a mathematical computation. It has since been replaced by methods that generate numbers from unique initial values, such as the time on a clock.

William James laid the foundation for psychology as a scientific discipline in the US

The breakthrough that changed our perception of the universe

In the 1920s, the Hooker Telescope helped Edwin Hubble make a discovery that forever changed how we see the universe.

Everything you know about Phineas Gage is wrong

A stray spark sent a 3.5-foot-long, 1.25-inch thick iron rod through the brain of foreman Phineas Gage in 1848, creating a scientific case that has attracted onlookers for nearly two centuries. His life reportedly soon spiraled out of control, with his behavior tending toward selfishness and chaos. Evidence of these changes is far less common, with Gage's story bloated by fabrication, scientific prejudice, and artistic license.

Supreme Court Justice Louis Brandeis once called states 'laboratories of democracy'

Louis Brandeis argued that federalism allows states to experiment with new policies without committing the entire nation, thereby allowing successful ideas to spread while limiting the risks of failure.
