"I will make you study calculus if you don't let me win!" is how I imagined this would go

I dont really understand how you're supposed to spot the "coincidences" if you can only see the encoded text. Although on the 3rd line I do notice "Ebi" and 9 letters later again "Ebi". Both of them just happen to be the word "the".

Little Timmy you’re going to use maths to make mad money and get all the sexy ladies.

The histogram at 3:50 is very clearly not normally distributed, so it's a bizarre decision to then compare normal distributions later on at 4:45.

I've been tricked! I learned math!

Could you not remove that text on the bottom right when you were drawing?

Why couldnt you just use cross-sectional area to compare volumes, because it is a circle and you don't need the volume, you just need the angle.

I was a sprinter at the beginning of highschool in WA State. After the first month, the sprint coach told me to go to hurdles with the reason being "Just trust me." I went on to the state championships in both hurdles events my senior year, standing at 6'3" on the podium.

In Mario kart 8 deluxe the mini turbo boost is greater with a high acceleration stat, so if you’re a good driver you will pass people even if their top speed is technically higher than yours. Interesting video though 😎👍

As a life long tennis player this remidms me of something lots of hating comments have towards the difference between men and womena matches, namely that you can never predict who'll win with the women cause "the women can't serve" (thats a ridiculous statement and everyone knows this). The difference between the men and women is that when the pressure is intense and you body is exhausted its far easier for a 6'2" man to get the ball precisely and powerfully over the net than a 5'9" woman. Im not calling for the height of the net to be lowered for women or anything considering that mixed doubles matches have both men and women playing at an insane level together

I know it's not the point of the video but acceleration is actually not that important at all. The most important stats that you should be looking for are speed and even more so the hidden stat of mini turbos that increases the effects of your turbos after sliding. But high acceleration is also on the combos that have high mini turbos, which is why high acceleration combos are still good even though the actual stat is not important.

I think the optimum is dependent on the condiment, most mayos you can tower quite high, so the fully flat cup is definitely the best, the ketchup depends on how runny it is, it varies between brands, but i would still say you can get more from a fully spread basket. The video demonstrates the best angle for runny sauces, never been to arbys, but bbqs are usually more runny

I've heard of a one-time-pad hard drive getting shipped by Amazon or some similar company as a worst-case post-quantum encryption method. In that case it would be much easier to securely send one large hard drive for many messages than the individual messages themselves.

Great video!

The fact that you stop when you get hit by an item is why the coin item was such a hated gamechanger. If you were up ahead, you no longer had a guarantee that you will be able to get something useful to shield yourself with, or quickly reach top speed to recover (mushroom).

How about just getting better at the game ?

Interesting video... then you got to the maths and started using inches only for height. It kinda broke the momentum of the script having to translate into feet and inches, then again to metric. Talk about cognitive overload

i nearly always win with a large character, mr scooty, and the littlest wheels

Scientists and Engineers are ALWAYS sloppy and cutting corners in their low tier dumbed down version of mathematics,and Mathematicians always have to come and clean up the disgusting displays of mathematics put together by Scientists and Engineers with no appreciation for precise mathematical definitions,theorems and proofs.

Real Mathematicians know this is DUMB,Scientists and Engineers are sloppy and not as rigorous and sophisticated as Mathematicians when it comes to problem solving,and this is evident in this clickbaity video.

It can be made stronger by modifying the encryption key at each round of encryption. For example, the cypher can encrypt the first set of letters. The original letters can encrypt the next set, or the encrypted first set of letters can encrypt the next set. Any combination would work so long as the first set of letters could be decrypted using the key. AES: CBC, PCBC, CFB, and OFB use such a method. The key could also be modified by some agreed method between each round as well: CTR.

"Statistics reveals unfair genetic bias in all Olympic events."

It's a bit silly to label the current hurdle sizes as "arbitrary" as if you want to have a hurdles event, some kind of standard will need to be established, and whatever it will be you'll always be able to call it "arbitrary". Saying so doesn't add anything to the discourse. Also, the international bodies aren't interested in the aformentioned solutions not because they're wholly unsympathetic to the concerns of the athletes but because those solutions are crap. Having multiple hurdle sizes requires managing x times as many hurdles as well as individual needs of every athlete every heat, it's just not practical. Granting the ability for the athletes to space them out is also a huge time investment in a tightly run ship that are the highest level tournaments, not to mention the concern that everyone has to jump the same number of hurdles, and run the same distance at the end of the day. btw this is also why long jump and pole vault aren't proper counterexamples of this already being done. The former doesn't care about total distance travelled, only from the jumping point, and the latter doesn't take horizontal distance at all into account, so spacing the approach out has no baring on finishing the given task. And finally lowering the hurdles doesn't actually make the sport more accesible. Number 1: someone out of the optimal height range right now can still compete, its just that it's harder. Therefore any increased accesibility is in the form of making the race easier for shorter athletes. But number 2: even that isn't the case. Because while the race would indeed be easier for them, it would also be easier for the optimal height athletes as well! Meaning that finally, this change would only aid accesibility if you prove that it make the races easier MORESO for the shorter athletes than the taller ones. Which would be hard, and even if proven, would be a way minor impact that it sounds. But still number 3: even if you insist that that minor impact is worth it, the new smaller height would still be !!!ArBiTrArY!!! It's noteworthy to point out that this sport specifically creates a lower AND an upper bound of innate fitness for optimal performance, but it's not an issue to be solved. It's not "unfair" per se as, well... sports test physical fitness. Obviously people less naturally fit will do worse, it still doesn't stop the hardest workers from overcoming that (as you mentioned at t he end of the video). And the way the event is set up is an intelligent design build up through the long tradition of athletics, and there are good reasons for why things are as they are.

why not run backwards

"my son spencer, who is perhaps 15" woah woah woah... PERHAPS?!?!

Normal people: Let their kids win most of the time MathGuy: No!

As a cryptographer I love this video

Not to mention hurdle races are already one of the most time consuming and logistically tough events to set up and run, custom heights/distances would never be feasible

I wonder how much stronger the Vigenere Cipher would be if you used a "secret" alphabet order. In that case you can't decode a whole group that corresponds to one of the letters in the key at once.

(Knowing that it's much easier to decrypt a message encrypted by another message) I would have shifted the message by a certain amount (say 30 positions) and subtracted that from the original message. If you guessed an amount that corresponds to the length of the key, then the result is a (part of the) message minus another (part of the) message. And if you run frequency analysis on it, you can use the fact that E-E will be the most common combination of two letters followed by things like E-S, S-E and S-S. All frequencies will be much closer to 1/26th than in a simple substitution cypher, but will still be detectable for a long enough message. This is kind of like what the technique around 4:50 does, except that that only considers occurrences of E-E and S-S, but ignores E-S and S-E.

Just as a note: The One-Time-Pad is not only improbable to solve by guessing the key, it is impossible. Since you could decipher the encrypted text to any other text of that length, you have no way of checking, wether you had the right key.

Key: paradox Plaintext: So what is the answer? In truth, the when-will-I-use-this question is unfair for the teacher. She doesn’t know when you specifically will use it because she can't see into your future. The difficulty in answering this question lies with an implicit assumption hidden beneath the question. The student has an idea of the kinds of situations that she will encounter in her life, and when the response from the teacher doesn’t apply to any of these situations, the mathematics seems useless. But it is fraudulent to assume that we know at a moment of reflection the kinds of situations in which we might use something. Why? Because we don’t know what we don’t know.

Spoiler warning... The key is "paradox".

Here is the code to break at the end of the video so you don't have to transcribe it (it is also in the description): Ho nhdh fh tye dbplei?

What about this method. Both the sender and user have the same dictionary. Then the secret key could just be a word in the dictionary, but that is not what you use to code and decode the message. Both use the letters that come right after the key word in the dictionary and go as far as needed for the message. This makes it a one-time pad, but solves the problem of passing a long secret key.

Mathematical cryptography was my favorite math class in college! I like cryptographic stuff, it's really interesting, and an oddly practical use case for number theory.

0:30 in this precise situation, going backwards (i.e. to the right) is likely optimal. Chances are that if there is a vehicle in the next lane, it is farther away from you. If it's not, then you may as well stand in the middle and hope both vehicles swerve a little bit. If the other vehicle is very small, jumping over it is more safe, even though you will probably still get injured. A moving vehicle can't hurt you very much if it's mostly under you.

I love the editing of this video, you can see the effort put into it while it also feeling kind of "home made" if that makes any sense, I love that everything is explained only using drawings or images

Please put the secret message in a comment or the description, thanks!

I can send you a otp using the square root of 2 I use as many digits as I have in the message you would know the length of the message and the next message would continue from where we left off

Cryptography is just some of the most fun math.❤

this channel needs more subscribers 😭😭😭

Great video!
