I don't even know if this makes sense. Boo cold. Try playing with this: www.khanacademy.org/cs/pascals... en.wikipedia.org/wiki/Ulam_spiral My personal website, which you might like: vihart.com
+ThunderJelly No. That kind of prime is called a Mersenne prime they are 2^n-1 not all of them are prime. The reason why the biggest primes are Mersenne primes is because you only have to apply an algorithm to the exponent to see if it is prime vs. having to apply a formula to the whole number, but even just working with the exponent/n takes a standard computer a few months of non stop computing. 2^4-1=16-1=15 and 15 is not a prime.
*HaphazardDisastard* Will you (please) keep updating new prime numbers discoveries? It's fascinating to see how long (and how many mathematicians!) it takes between one and the other
@debblez Some people aren't as good at this stuff as others. I get confused by a lot of her videos cause her explanations are a bit too fast and intricate for me. You all seem to understand it though, so good for you! Some people are still trying to catch up. Atleast we're trying?
The triangle with colors is exactly how I come up with algorithms in software development while I had terrible grades in maths: at first I try the "complex way" (= using numbers) because it's what comes first naturally, then I try to "simplify" it (= using colors because we don't need to know the exact value of each circle) and finally look if there is any pattern. Problem is, you can't explain this method in a test 😅
I believe the idea is because it's counting. Even bees understand counting. The idea of the Golden Record (a record sent into space with a bunch of information) was that aliens would have to *find it*, not just have it happen to land on their planet because thats an unreasonable belief. It's not that much of a stretch to think they would have to know how to count to find and retrieve something in the middle of space safely. And as for recognizing, humans can recognize math in little pictures with cats and whistles if you think about it long enough, so it would take a while but again assuming they know how to add and multiply because they went into space to get a shiny disc, they could figure it out eventually.
bro, two hours ago I had no idea what a sierpinki's triangle (still don't know how to spell it) but when she was doing the Pascal's thingy I said out loud "hey that's gonna turn out like sierpinki's triangle" I feel very educated. thank you vi.
You are amazing! Math is one of my favorite things, but I'm in calculus, so we don't get to relax and do cool stuff like this with numbers! (We do other cool stuff, you know, with variables, usually.) I like this very very much!
you can't understand this video if you can't understand basic math, therefor you are a fool to think that your math teacher teached you less than her. Also what she "teaches" you is not useful at all in any way or form in your averages Joes life.
@@darkgrundi9543 dude I mean she just devises from years ago over and over again, NewZealand curriculum sucks, plus I want mean, at all so why are you?
agreed! How about, hay Vihart, I think your passion for math is infectious and I have always known that exploring math for yourself is exciting, but I never had anything to think about, because I could never start. Thank you for your long hours of editing, filming and planning to crate such a comfortable channel for this difficult subject on which you shed light on.
Half of the people are like “Nani what’s happening”, the other third is like “woah replace my teacher” and the other seventh is like “ and here’s some more math you might be interested in” and the other forty-seconds is talking about something else
My favorite Pascal triangle patter is coloring by multiples of 5: every 4 rows of the triangle you create a bunch of smaller triangles and they are either: Point up with the two diagonal edges all of the sam color Point down completely filled by multiples of 5 And if you keep track of all the point up triangles and put a dot for every triangle color in another triangle you get the same colors as the starting triangle! It’s like a series of triangles you could track down to infinity!!!!
In this video I believe ViHart had done a amazing job in contributing a mathematical theory in a really fun way. I personally didn't like the first one named Stanislaw Ulam, but I really enjoyed trying Pascal's Triangle. The reason why I might have thought this was more enjoyable since this complicated pattern with numbers, is just depends on a equation that was shown. Anyways I personally enjoyed this video the most. I admire her by the way she talks about all of these things, when i have trouble with my odds and evens.
THEY JUST KEEP ACTING LIKE: ‘oh, you know me, just a dummmy-dumb-dumb, doodling in math class~!’ ALL THE WHILE COMPLETELY BLOWING MY MIND WITH AMAZINGLY INTERESTING MATH IT’S JUST SO FUNNY TO ME-
In school, I always had a hard time with math because my teachers couldn't grasp the fact that I have a creative mind, not a technical mind, making me a visual and hands-on learner. The teaching methods they used just made everything so complicated, and even though your method is a tad confusing too, the colors and visuals you give make it a little easier for me! :)
This video for me was a bit hard to track but provided a lot of good information. I have a hard time identifying prime numbers immediately so the first game was a bit hard for me to understand. Pascal's triangle has always been pretty cool to me. I liked how she showed it with colors as well. It gave me a new way to look at it. I still really want to know how it was figured out though, and if it was purposeful or not.
Bahaha, your prime ribs remind me of me in English calling Hamlet Ham and Polonius Polish Sausage, hoping not to interchange those for their names on tests 😂
I particularly enjoyed doodling the "look and say" numbers. Where you start with 1, and that's one 1, so you write 11. Then that's two ones, so you write 21, and so on. I never discovered anything cool about it other than the fact that it's impossible to get any number higher than 3 unless it's the number you started with.
I did a math thing In class we're doing scientific notation, and I did the entire worksheet before the teacher finished one, so I decided to make a game. I made these rules; 1-2 is up 2.1-4 is right 4.1-6 is down 6.1-8 is left and 8.1-10 is up, then right, then down, then left. I made some funky shapes and even made some math creatures.
It was inspiring that the guy who found the largest prime number won 100,000 dollars! I did not know that prime numbers were used to talk to aliens so that was very shocking to hear. But it did make sense as aliens and humans might have to communicate through mathematics if not a mutual language which is bright up in the video. Pascal’s triangle was in this video and I learned it in algebra 2 but I’m still a little confused by it, especially after this video. I liked that this video was about math games to try to make math more enjoyable and less stressful. However, the games are so complex it might be more confusing than just being in math class. I like that she suggests to make your own math game though because then it might be more fun and catered to someone’s actual interests in math.
