A superposition of?

In statistical mechanics there's a concept of "ensemble average" and its provable that if you have a system, the average state of the system over say a 100 realisations ("ensemble average") run for 1 second each, is equal to the the average of one system run for a 100 seconds - under some assumptions of course.

I don't know enough a about human biology to make a statement about whether any of those assumptions will hold true, but maybe someone else will.

I mean the data lacks any person's sleep history, but if there is a cohort of bad sleepers, as a group you get a collective pseudo-history (because altough study is done at the same time they are in different life stages) that is no-one's history but might track the average well for that cohort AND take into consideration more than a week.

In the similar way sampling the height of 1000 of 1M people will give you a good estimate of the average.

>We'll send you $105 through the sketchiest way possible, PayPal, to make sure you feel like you're getting scammed, because you are!

What are the good ways to be sent approximately this sum of money nowadays?

Airwallex, Stripe, Wise,

Direct bank transfer (which above will support OR just a regular bank)

Requires trust yeah (except maybe the regular stripe credit card txn)

My Oura ring establishes a consistent sleep rhythm and nudges me when it is approaching.

I read that with a lower case O at first and was intrigued!

I realize this is far off, but I'm hoping that someday I can get gene therapy to get this.

The assumption is what you do when awake those extra hours is more productive (or fun of whatever you are aiming for...) than asleep.

Sleeping you has the disadvantage it cannot keep score. Wake you has "I completed X today and Y yesterday". Advocate for sleeping you!

That’s because this is in UK Biobank, a cohort of >500K Brits and collecting actually in such a large cohort is a miracle, let alone for multiple days. All thanks to the people who volunteered into the study. Would it be nice to have even more? Sure. But at that scale, patterns start to emerge.

styyyaaa · a year ago

Yes. Any statistics buffs here who can tell me:

Is 500k brits for 1 week as good as 5k brits for 100 weeks.

Effectively with so much data aren't you getting a superposition anyway.
