8:48 duckies!!

Please!!!!! Don't drink anymore. I almost died from drinking at 16..I'm 45 now...and I'm staying strong. I drank at a wedding recently and fk I could have kept drinking. You are doing a great job. You have a great idea and channel. Stay Strong!!!!!!!!!! If you are having a hard time with drinking just remember that there are other staying strong WITH you!!

28:38 Congratulations on a month without drinking. Alcohol is a horrible drug and its affect on mood can sneak up on you. Combined with its addictiveness it can be a horrible thing. It's amazing that you are trying to defeat it and still be productive with creating videos. Also the bravery to tell us you have a problem should not be underestimated. We're on your side and rooting for you :)

In fact, this is one of the common ways to cook eggs in Korea, which is called rosted eggs in English. Or maybe they just call it a Korean sauna egg.

I hope we can get some math crossovers in grade -3. Maybe with numberphile

After grade -infinity, I can’t wait for grade i

Polyester lab coat is no good. Buy a proper one, for real. And big up for mentioning and confronting your alcoholism. Stay sober, it isn't worth it.

From what you've said, that means for every twin prime pairing, the number between them MUST be divisible by 3.

Bro! You’re in the east bay?

Nice to get a peak behind the curtain of this awesome and weird channel

Thanks for the quality content you've been making. I'm very much looking forward to the first threeven numbered grade!

Those trees are epic!!

Love you too, Domotro 🧡🧡💛💛💙💙

Dude, alcoholism is some of the scariest shit. If you're struggling with it, that's not because you suck. It's because it's a hard thing to do. The important thing is that you're working on it and trying to do better. As far as how it affects videos goes... if it helps you to think that you're doing it for our sake or that you'd be letting us down if you had a drink, then by all means see it that way. But what really matters is you. You don't owe us videos, but I think you owe it to yourself to take care of yourself. However hard it gets, don't give up struggling against it, because you deserve better than that.

I fully expected the lab coat to be flame retardant. Someone buy this man a fireproof coat.

I’m so confused what’s the difference between these two channels? Combo class has less subscribers, but domotro from combo class has less views on big videos

Yay -3

Thanks for what you're doing! Really enjoy whatcing your vids on math, on fruits, on game theory and all the stuff! Hope to see you in grade -3! Love from Russia!

You are wholesome, can't wait for Grade -3!

Okay, now sit domotro down and make him watch "this house has people in it". The kids love the cursed content.

That was great man. Just finished it and it made my night. Love to see the things you care about pull you through.. they're good things. 💚

You might want to buy a sweet sweet flame-resistant lab coat like NileRed has! Although, they're blue. They're also 800 dollars

Hell yeah, just in time for my birthday

I love the style of this channel. The background mixture of nature and chaos provides a steady baseline of engagement for my brain. It keeps my mind from wandering and focused on the content. I hope to see plenty more of “things interacting with gravity in interesting ways” in Grade -3 :)

More creatures!!

Good on you, man. Keep it up. Your mind is amazing. Don't water it down...

that potato grew some testicles/ovaries lol

An amazing video! It's great to see you come out of this grade with the same eagerness as the end of grade -1! Hoping for a great grade -3

About to go to bed, checks phone, sees Domotro uploaded Grade -2 finale, postpones going to bed.

This is the final episode of Grade -2 of Combo Class. It is like a documentary about the past era of my life (and about the past grade, although most parts are made entirely of unseen footage). I spent a long time making this video and I hope you watch the whole thing, but here are timestamps of its different chapters: 0:00 - Part 1: Introduction 1:58 - Part 2: Injuries 6:09 - Part 3: Adventures 8:22 - Part 4: Animals 15:44 - Part 5: Plants 20:46 - Part 6: Evolutions 45:51 - Part 7: Camping 28:27 - Part 8: Secrets 30:18 - Part 9: Cycles 33:58 - Part 10: Conclusion To be continued soon in Grade -3.... Consider supporting my videos on Patreon: www.patreon.com/comboclass (More links and information in the video description)

Yay!!! It’s finally done, I’m excited for Grade 1101 (in base -2)

These problems are largely due to the difference between inclusive and exclusive counting and its interaction with modular arithmetic.

Which infinity represents the total amount of infinities!?

I’ve been playing around with including powers and subtraction as an option. So far, i think 15 is the first whole number to need subtraction in this system. ((1+1)^(1+1+1+1)) then subtract 1.

is there any reason for this "clone" stuff or is that just a coincidence? does it happen in other bases too?

Domotro's Law

Very very very interesting 🤔🤔🤔

19:28 “The OEIS calls this the Mahler-Popken Integer Complexity sequence.”

If you study Cantor's diagonal from the perspective of the skew diagonal using a skew symmetric list, you will uncover something interesting. It's easier to visualize using binary numbers where each digit can be either a 1 or a 0.

Bro, you are literally a genius. You would be one of the few people in the world who would understand the maths used by God in nature and in the scripture.

ternary base: 0,1,2.

Proof by contradiction is problematic in this context. The reason is that a very similar problem can be constructed in which you prove that infinity is irrational by contradiction when in fact the contradiction simply means infinity does not exist as a rational number. It also does not exist as an irrational number. This is to say that encountering the contradiction is not enough to prove irrationality. It can only prove that your assumption is not true. So if you assumed a rational solution exists, the proof by contradiction result becomes “a rational solution does not exist.” To affirmatively prove irrationality you must also prove that a solution exists and is irrational. However we already know no rational solution exists so we must assume an irrational solution exists and then prove the assumption true. Good luck. These are some reason why it is better to think of pi as a concept or an equivalence class of integer sequences rather than a number. It is also describable as an algebraic relationship which is also a concept. Like infinity which has an unbounded most significant digit, irrational numbers have unbounded least significant digits. The unbounded nature is what makes these mathematical things concepts rather than numbers. Infinity and irrational numbers have in common the fact that they contain an infinite amount of information. So in summary, proof by contradiction works, but it only works to prove the negation of the assumption. There does not exist a rational expression for sqrt2. This is not the same as claiming sqrt 2 exists and is irrational. Making this unjustified leap is one of the greatest logical blunders of modern mathematics.

This phenomenon applies to gear design as well. There is a defect called hunting tooth wear that occurs when the same two teeth mesh and develop a unique wear pattern between them. When this occurs, those two teeth wear out faster than any other teeth. So a more reliable gear set is one where the tooth counts are co-prime so that the frequency in which the same exact two teeth come in contact with each other is as low as possible. This maximizes the chance of even wear amongst all teeth.
