Welcome to our channel, Discovermaths, created by Spanish mathematician
Juan Medina and myself, David Darling.
Mathematics is much more than routine calculations. That's what we aim to show in this series of videos, to which we’ll be adding week by week. Basic maths questions have behind them a surprising number of fascinating concepts. By explaining these concepts to you, clearly and simply, we’ll greatly increase your mathematical level.
Mathematics is also everywhere around us: in science, technology, economics, and is key to all these and other fields. We’ll show you the maths at work in a wide range of applications.
Get ready to join us and learn a lot. You’re going to find it easier than you imagined to gain a deep knowledge of mathematics.

The cake-cutting problem
How can a group of people cut up a cake so that each gets what they consider to be a fair share? In its modern mathematical form, this classic problem of fair division dates from the Second World War when the Polish mathematician Hugo Steinhaus tackled it using a game theory approach.

A new proof concerning the Mobius band
Просмотров 7208 месяцев назад
The Mobius band one of the most intriguing objects in mathematics - simple in appearance yet with complex properties that have kept theorists busy for more than a century. One of the most challenging puzzles seems deceptively straightforward: How small can a Möbius band get before it intersects itself?

Mathematics in the art of Albrecht Durer
What I heard : five to the four to the power of negative three added by five which is going to 2 and we take that and minus it by ten and we get 8…. THEEN WE
There is something new about Albrecht Durer ruclips.net/video/YV4QN0ZSNcc/видео.html
Mr eagle 2 is not touching the brackets but it is ÷2
Mr Kyle 8÷2(2+2)= 8÷2(4) = 8×1/2. ×4 =32/2=16. This is your mistakes. 8÷2×4= 8÷8. You got 8 by saying 2×4. But it is ÷2×4=2×8=16. Thanks. No offence just trying to be helpful. Maybe I am a bunch of fools. I respect your opinion
8÷2=4×4=16. Simple. I can't understand what all the fuss is all about
X²-x³/×-¹=ײ-1×=-x²
Thank you ! you took a bug out of my mind since at school they explained logarithms but it wasn't clear where the calculation of the mantissa came from!! it seemed like a secret, you took the values from the log tables and that was it!
Grazie ! mi avete tolto un tarlo dalla mente da quando a scuola spiegavano i logaritmi ma non si capiva dove veniva fuori il calcolo della mantissa !! sembrava un segreto , si prendevano i valori dalle tavole log e basta !
Natural numbers are these used to describe or explain natural objects. To count things/items/animals we meet in nature. For example, "the cat gave birth to 4 kittens", or "9 apples fell off the apple tree". That's why only positive integers are natural (not the negative integers, nor the decimals etc). Zero is never used to count natural items, ie you can't naturally use zero to count (?!?) and say that "there are 0 oranges on the table". And why say 0 oranges and not 0 apples? Since you never use 0 to count natural objects, it can't be considered a natural number.
I am about to turn 48 this year and today on the subway I heard a 4yo ask his mother Explain me, why 5×0=0, and I realise I have no clue whatsoever about it. I stare at him appreciatively, he was even an immigrants' son and he was speaking our language, not his mother language. Excellent video, plain, simple, without paraphernalia of any sort, just the answer I need, thank you.
One of the very many extraordinary things about these Polymaths and geniuses was their short lifespans! So this man and others packed in an enormous amount of passion and effort in no time. ❤
Thank you as a tiler wanted to expand his knowledge in geometric work I’ve come accross your video and also managed to find a decent translation in pdf of harmonices Mundi with what seems to be all the sketches too! Ancient knowledge which is vital
Soooooo long windedddd

7:07 - the 1915 & Hardy looks a little out of context here :)
Havent heard about Polya and Mertens conjectures - Mertens wasnt defined here but i found that it is based on Mertens function which uses Móbius function :) and it was stated by some guy called Stjeltes (Dutch) who wrote a letter to Hermitte :) - everybody knows Hermitian transformation or polynomials :) or a Hermitian array in quantum physics.
very good video of old facts :) but the quality is very good - i am watching at 360p and it looks two times better than that - in reference to other content watched at 360p
Very interesting paradox, discus is more like a wing than as a cannon ball. Nice channel, came here watching for some goldbach conj. observations but stayed longer :) - pity only 2,6K views, only 70 likes , as much as 9 dislikes and 2 comments. Good audio good content - will be coming back :). BTW - There is communism in Canada, US, Europe... not sure if there still is communism in china... but they're going to cut off the dependencies with europe and US.
Dude. You say he's turning right, but he's turning left. Not helpful.
Tien's signature attack from Dragon Ball Z being called Tri-Beam in the English Dub when it makes a square now makes sense.
Algebra says that all variables have coefficients. ie 1x The contents of a parentheses are a variable. It's a function that has to be completed before the next step. It's not possible to have something in parentheses without a multiplication by a coefficient happening immediately after. That's what algebra specifically states about variables. It doesn't matter what the expression, you can replace the entire thing with a variable 1(x) which has the simplest tree possible: * / \ 1 X Whatever the tree was before, it was replaced with this, and now X is a separate tree. So every parentheses creates a NEW function. A multiplication happening immediately after a parentheses is UNAVOIDABLE. Even the most basic tree has an operator and 2 arguments. The result of a function X isn't an operator, it's an argument. So there has to be at least a multiplication by 1 to make the simplest tree that can replace the original tree without changing the answer.
Mr Chris you are confusing me with your essay about the tree. Maybe I fell from a pawpaw tree and hot my head😂. But read my comments and see whether I still have a hole on my head. Thanks

Yup, this is why so few people like math
😂😂😂 angrej teacher
Take something like make that requires concentration and throw in cheesy music. Probably not the best way you could have presented this.
👏👏👏👏👏👏👏👏

Meanwhile, you're the only one I've seen that comes close to the right answer, but your answer ends up being wrong too.
Salut les kids de maths expertes ! Suprême Leader Suprême.
What I'm hearing is, 1 is algebraic, and 0.999... is transendental. Therefore, 0.999... ≠ 1.
Why tf someone puts a dramatic bgm on a math problem? Are we solving a question or going on adventure , was such difficult for me to focus on the question .

Beauty.
I was really impressed by the detailed explanation. Thank you very much.
What about applying the product rule and switch positions. There is no rule for a division but it would make the 16 more viable.
Nice❤🎉🎉
Straight headwind is actually not the most optimal direction, ideally the wind should also come in a bit from the side of the athletes dominant hand. This way the normal 5-10 degree right tilt of the discus which some consider optimal allows the discus to anglematch the apparant wind as it climbs resulting in minimal loss of velocity. As the discus starts to fall the airflow over the tail end starts to detach thus losing lift at the tail end. Gyroscopic precession comes into play now that the center of lift has shifted forward and the discus starts tilting left (another reason why starting it with a right tilt is beneficial). The more the discus tilts left the harder the wind will move it sideways relative to the original direction of travel while slowing down its fall somewhat, in addition to this the tilt angle in a strong crosswind will also shift forward a bit since the discus will tilt on the axis of the apparant wind.
How had I not come across your channel before? This is AWESOME! I am now a subscriber and looking forward to going through your extensive collection. Thank you for your work.
Like man🎉🎉🎉
🎉🎉❤❤
😂ok i will stop it
First problem could be used on day 1 of "Erdos-someoneelse" spork-in-the-road theory. Paul and I were talking about the slide @1:53. He even went as far as to demonstrate to me all published work (2024) on this problem. If asked for my input: "Paul, you seem like one person drawing a single point with a single pencil" Akin to (P,dOf,pencil) =P+dOf^(p/frame). Spice it up a little, 2 people or 2 pencils or 1 person 2 pencil 3 dOF, ......(time passes as I explain every permutation of his problem).....
Why does adding one after multiplying all of them ensure that none of them will divide into this new number
nice proof (: Thanks
It should be practical example.
