POO-EE! Roman Toilet Seat Found Near Hadrian’s Wall

How would you like to root around in a 2000 year-old toilet?! The Romans created aqueducts, newspapers, and bound books… but did you know they helped create the toilets we have today?
Archaeologists at a Roman excavation site in Northumberland have recently uncovered a wooden toilet seat…that is 2000 years old! While it looks a bit more basic than the toilet seats we have today, it shows that they were very concerned with cleanliness.

In communities all over the world, people are doing just that. Or something very like it.

Rock, Paper, Scissors… Robot???

rock paper scissors robot

The game rock-paper-scissors is well known around the world. We’ve all used it as a choosing method, or simply as a game! The easiest version is played between two people. Both players choose one of the three shapes for one of their hands, and reveal their choice at the same time, hoping their choice beats their opponent.
It’s nearly impossible to gain an advantage over your opponent, unless you wait long enough to identify their choice before you make yours, but the chances are that they will realise your cunning plan and call you a cheater!
This game is not simply a choosing game. There are mathematicians dedicated to constructing algorithms for the best strategy to win, and scientists devoted to creating unbeatable robots! In fact, researchers at the University of Tokyo have created a rock paper scissors robot that wins at rock-paper-scissors 100% of the time.
