"6 hours free per week"???

Prathyush Poduval

@Blue Yeah do it

ACuriousMind

I hope this doesn't mean you only have 6 hours to yourself per week

Prathyush Poduval

@ACuriousMind No No, it's the free period in the school. I do have a lot of free time after class :P

Since all the labs are over, we don't have anything to do in the time (2 hours for each subject *3)

@Slereah but it s supposed to be another interpretation by itself right? with ideas such as, the state of a system is only defined with respect to another one. This is well different than in copenhagen right?

That will leave the other half of the disk free for Linux

the waves are the perturbations

tips hat

Joshua Lin

Anyone here do measure theory? Funny question; find the measure of all reals in [0,1] that have decimal representations such that there are infinitely many n (in naturals) such that the first 10n digits of the decimal representation has an equal number of 0's, 1's, 2's, ... 9's.

It was on my exam, I couldn't do it; and I still can't :'( sad days

It's gotta be either 0 or 1... right?

Sir Cumference

@Slereah Welp, thanks for tipping over my hat

Or, at least it'd show up if the chat updated gravatars faster

Slereah

Well there's the Champernowne constant

0.1234567891011121314...

I think it's basically gonna be like

0.000000000..., 0.111111111..., 0.1212121212...., etc etc

Plus their permutations

then you expand to 100 digits, with 0.0000000000000000000...., 0.00000000001111111111..., 0.0000000000222222222..., etc etc

plus permutations

Not a clue what the measure would be though

Joshua Lin

yeah so the first part of the questions was to prove the set is actually measurable; and im pretty sure theres only one way to do that, you let A_n be the set of all numbers such that the first 10n digits of decimal expansion have an equal number of 0's, 1's, 2's, ... 9's, and then our set is

$$A = \cap_{k = 1}^\infty \cup_{n = k}^\infty A_n$$

So I thought from that you could get some sort of sum (by using the permutations idea, and maybe terms telescope or something) but no luck

I'm like 60% convinced that the set is measure zero, so I thought maybe some cool tricks would work but idk lol

Slereah

Well

I think it's computable

And computable numbers are countable

So there's a good chance that it's measure 0

though I'm not 100% sure it's computable

Joshua Lin

9:46 PM

Wait aren't there like normal, uncomputable numbers?

Slereah

I don't think normal numbers are in the category of numbers where like

Joshua Lin

I think it's true that almost all numbers are normal; so throughout the exam I thought it was also high chance that almost all numbers satisfy the property

Slereah

The 10n first digits are certainly of that composition

For all $n$

Joshua Lin

Yea normal numbers are different, but sorta related?

Slereah

I forget the exact definition of normal numbers but there's some probability distribution thing

And I'm not sure that set obeys it

Joshua Lin

9:48 PM

I think it's just if you look at the proportion of 1's, 2's, ... they all limit to 10%

Slereah

it might be a good idea to stick with binary representations for the proof

The decimal version should be the same

Joshua Lin

hmm

Slereah

You might be able to represent them as some binary tree maybe?

First digits are 0 or 1, then 00 or 11 or 01 or 10, then 0000 or 1111 or 1010 or 0011 or 1100 or 0101

etc etc

Wait, not quite

Well, it will be of a smaller cardinality than that tree

Joshua Lin

Wait I think you're thinking of something different
The condition is that for infinitely many n, the first 10n digits contain the same amount of 0's, 1's, 2's, ... 9's

So it doesn't have to satisfy for all n, and when it does satisfy, it needs n of each digit

Slereah

Ah

Hm
