I know it’s a unit of energy but in engineering, we colloquially just use it as BTU/hr which is something like .3 kW

It's the adrenaline rush, I bet. It feels like a drug. The recognition is probably nice too.

Lol. Whoosh

Also, consider your chances of dying due to some plague or real military encounter or just "old age" starting at 40 instead of 70... It's not like jousting is gonna increase your chances to die that much (🤣)...

The problem is wrongly stated. 2500 kg is a mass, not a force. Also, no specifics of the atmosphere are provided. Is it, for instance, STP? Also "How fast" is not a good question. This projectile will have a non-linear acceleration due to air friction. If it goes transonic, it gets even messiet.

Football was a very deadly sport Who ever was carrying the ball got piled on. Broken bones and death were common, Things changed with protective gear and the forward pass.

Do you have any examples of the shed style vs earlier?

It flexes at the point of impact.

What do you mean humans generate 500 BTU each? Is that per second or per hour?

Henry VIII seems to have been deeply affected by a jousting accident when he was young.

When you have a very large building you wind up having a reduced ratio of surface area to volume. The thermal energy inside the mall has a harder time finding a way out than it would in a smaller building because there's just less building surface in comparison. It takes time to get truly cold.

Being rigidly attached to the 6.6 sextillion tons of planet earth does tend to diminish the magnitude of the change in motion though.

Tempered glass is like a rubber band stretched out tight. Ceramic is like a razor blade. Once that razor blade nicks the rubber band, it introduces a weak spot that creates a cascading failure and the entire thing tears itself apart.

Any reason why? I'm taking a trip to DFW soon.

Thanks!

Tournaments were dangerous, though the equipment limited this, however there was a lot to be gained from them in terms of honour, reputation, status and hard cash. William Marshall became wealthy from his success in tournaments and attracted the attention of the royal family, he went from penniless second son and knight-errant to the right hand man to 5 kings, regent of England and Earl of Pembroke.

Migraines affect vision and balance. They can also last for several hours and put people out of commission for days. Sometimes medical pain relievers don't affect migraines like they would help with headaches.

Also an interesting tradeoff between efficient protection and redundancy. E.g. if we had eyes on all our fingers we’d probably be ok to lose a few, but also a lot more likely to lose a few.

Eyes, ears, noses, and tongues take a lot of energy to make and maintain, so having them all in one “take extra good care of this” spot is a pretty good strategy.

Medieval Europeans did a lot of dying in the winter. Old people, very young people...

A lot of the winter survival tricks are either not viable or no longer worth it. The solutions of today are better, it's just a matter of getting enough consensus, in most cases.

I've been in some small countries customs where it's just a standard 8' drop ceiling with like 3,000 people queued up, definitely feels super claustrophobic.
