AI Thread Summary
The discussion centers on the reasons for sleep, suggesting that it serves to allow the brain to process information, solve problems, and recharge the body's organs. There is a mention of fatigue being linked to the body's oxygen levels, with yawning seen as a response to low oxygen intake. It is noted that during sleep, the body's oxygen consumption decreases while intake remains stable, potentially helping to "catch up" on oxygen needs. The conversation also touches on the effects of caffeine, humorously questioning its role in oxygen supply, while emphasizing that the stimulation from caffeine does not replicate the restorative effects of proper sleep.

Why do we sleep? Is it because our brain needs time to move and solve problems, and recharge energy to our organs? And is sleep sub consciencous (sp) or unconscience (sp)?

I read some where that fatigue is caused by the bodies inability to acquire enough oxygen to keep everything running. This is what causes yawning, an attempt to get more oxygen. During sleep the bodies oxygen use goes down, while intake reamins about the same, essentially catching up.

Not sure if that's right, but i remember reading it.
 
From which it is easy to prove that caffeine is a good source of oxygen !

Hardy har har. But a caffeine high does not feel the same as being well rested.
 

Thread 'Predictions for the Nobel Prize in Physics 2025'

Similar to the 2024 thread, here I start the 2025 thread. As always it is getting increasingly difficult to predict, so I will make a list based on other article predictions. You can also leave your prediction here. Here are the predictions of 2024 that did not make it: Peter Shor, David Deutsch and all the rest of the quantum computing community (various sources) Pablo Jarrillo Herrero, Allan McDonald and Rafi Bistritzer for magic angle in twisted graphene (various sources) Christoph...

Thread 'My experience as a hostage'

I believe it was the summer of 2001 that I made a trip to Peru for my work. I was a private contractor doing automation engineering and programming for various companies, including Frito Lay. Frito had purchased a snack food plant near Lima, Peru, and sent me down to oversee the upgrades to the systems and the startup. Peru was still suffering the ills of a recent civil war and I knew it was dicey, but the money was too good to pass up. It was a long trip to Lima; about 14 hours of airtime...
