However, Penrose and others made a shocking suggestion: perhaps you already have a quantum computer - in your head! They suggest that our brains (or at least parts of them) are quantum computers, and that this is a key to understanding consciousness.
Since decoherence spoils quantum effects, I decided to use the decoherence formulas that I'd been scooped on to check whether Penrose's idea really worked. I first did the maths for neurons...
...
When I plugged in the numbers, the answer I got was "not very long at all", or to be more specific, about 10^-20 (then billionths of a trillionth) of a second...
...
I also did the maths for another model that Penrose had proposed, where the quantum computation was done not by neurons but by microtubules, parts of the scaffolding in cells, and ... (查看原文)
I've switched from collecting stamps to collecting cool questions whose answer is 42. Here are my favourites so far:
1. At what latitude was the book written?
2. What's the radius of the rainbow, in degrees?
3. At most how many percent of the gas around it can a black hole gobble up?
Feeding a black hole turns out to be a lot like feeding a baby: most of the material comes flying back at great speeds... Black holes can eat at most 1-1/√3 ≈ 42% of the gas around them. (查看原文)

暴涨理论部分解释得像💩一样,而且有个主流学术圈混得好的物理学家通病，爱吹自己认识多少牛人。好的和你一起吃过小龙虾的阿兰古斯给你把暴涨理论解释得醍醐灌顶你倒是原话复述一下呀特么给读者输出的是个？？？！
