In Slovenia, two extreme athletes were thrown into the air from the largest catapult in the world
A 360-meter chimney of a former coal-fired power plant was used for the launch. They were accelerated to 180 km/h in just 2.15 seconds 🤟
Every ball starts at one focus of the ellipse and flies off in its own direction. One bounce later they all pass through the other focus, at the same moment. 1, 2, 3, 5, 8 ... 377 balls (Fibonacci), and it works every single time. That's the reflection property of the ellipse
☝️btw..
Firefighters wear devices that start beeping loudly if a person remains motionless for more than 30 seconds. 🧯
This is necessary to quickly find a firefighter who has lost consciousness or is trapped.
That's why they try to move a little bit during the pauses!
