ELI5 Bayes theorem and conditional probability example.	y8ucgq	false	explainlikeimfive	Mathematics	Greetings to all. I started an MSc that includes a course in statistics. Full disclosure: my bachelor's had no courses of statics and it is in biology. So, the professor was trying to explain the Bayes theorem and conditional probability through the following example. "A friend of yours invites you over. He says he has 2 children. When you go over, a child opens the door for you and it is a boy. What is the probability that the other child is a boy as well." The math say the probability the other child is a boy is increased the moment we learn that one of the kids is a boy. Which i cannot wrap my head around, assuming that each birth is a separate event (the fact that a boy was born does not affect the result of the other birth), and the result of each birth can be a boy or a girl with 50/50 chance. I get that "math says so" but... Could someone please explain? thank you

ELI5: Logarithms and logarithmic function	xq83ei	false	explainlikeimfive	Mathematics	null
eli5, How do you do something for Pi seconds? How does that work? [Scenario below]	jso8jz	false	explainlikeimfive	Mathematics	What would happen if someone tried to do something for Pi seconds? I created this scenario in my head earlier today and I feel that there is definitely something I’m missing because the answer seems like it should be easy but i can’t seem to find it. Say that Person 1 (P1) Takes exactly 3 seconds to do a push-up, P2 takes exactly 3.5 seconds to do a push-up, and P3 takes Pi seconds to do a push-up. P1 would finish the push-up first, P3 second, and P2 last. This is obvious, since the numbers (3, ~3.14, 3.5) work easily that way. To an onlooker, it’s clear the order in which the push-ups were finished. But, seeing as though Pi never ends, how does P3 ever finish their push-up? In one way of thinking, isn’t it fair to say that, to a microscopic level, they never finish their push-up? The number of seconds it takes for them to finish it is so small, to some degree, they will never complete the task? But, we already know that they complete the task because Pi is between 3 and 3.5, and P1 and P2 already finished theirs, and so P3 must’ve, logically, finished theirs as well? Please don’t roast me to oblivion, I’m honestly looking for an answer that makes sense. Thank you! x
ELI5: What are Mock Theta functions ?	p4xhj7	false	explainlikeimfive	Mathematics	With respect to my background, I have just completed my high school with a knowledge of basic differential and integral calculus; I am nevertheless seeking to cultivate an interest in pure mathematics. On doing some research on the great mathematician Ramanujan, I found that he was prominent for discovering "Mock theta functions." While the name does sound pretty fascinating, I hope to find a good explanation regarding this topic. Thanks in advance !
ELI5: What do odds mean in gambling and how are they calculated?	p52bid	false	explainlikeimfive	Mathematics	I saw a post on gambling odds regarding who killed Mr. Burns, but I have no clue what all that actually means. How are odds like that calculated, distributed, etc. I've seen old movies take odds on things as simple as a chalkboards, but how can you do those calculations without a calculator keeping track of funds? Is ten to one odds the same as 10/1 odds? How can different people bet different odds on the same gamble (as seen with the post, Homer seeing really low odds and Maggie getting like 70/1)?

Eli5 what a Borel set is and how it could relate to modern music composition.	w7kih3	false	explainlikeimfive	Mathematics	I am in a music composers circle and here is the latest instructions, by a composer whose compositions are great but English is not: “The challenge is to invent a soundtrack or soundscape for a movie or a novel that tells the story of the Tribe of Borel. The language of this people is essentially mathematical demonstrations. The onlu imposed figure is that the first 8 bars of your track are identical to the last 8 . No duration limit. Play as you like with spirit of a collage. I think you can find mathematical demonstrations in different languages on youtube. But there are probably other ways to express this mathematical dimension. I hope you will enjoy it ! https://en.wikipedia.org/wiki/Borel_set" This guy is a great composer so i want to wrap my mind around this. Any ideas?

ELI5 If a sheet of paper can be folded into both a triangle or a circle, how come the total of the angles in the former is 180 degrees but the circle has 360? It's the same piece of paper.	l2jrg8	false	explainlikeimfive	Mathematics	EDIT: I am maybe being unclear. I'm referring to the paper side-on once folded. What I mean is that if you roll a sheet of paper into a tube shape, the end of it is a circle (360 degrees). But if you fold the edges into a triangle at the edge, then that's only 180 degrees but it's the same bit of paper.
ELI5: How do difficulty settings work in digital/video games? Example: Checkers or Chess.	l2p81g	false	explainlikeimfive	Mathematics	In something like Halo, I understand that you take more damage and give less damage as the difficulty climbs. But I don’t necessarily see any increased difficulty with the enemy strategies . Now with something like Chess/Checkers, the difficulty is ONLY about strategy. My input has a planned and programmed response from the computer player. I get that. But how is the difficulty here actually adjusted? What is the program doing or not doing when it’s playing to win, versus going easy on you? Thanks!

ELI5: Where does the p value come from?	dus64i	false	explainlikeimfive	Mathematics	So i know the value needs to be 'satistically significant' for an experiment to be valid and that the variable chosen is explaining the outcome. I also know it needs to be p<0.05 so you know it's above the 95% confidence interval and that the value chosen is explaining the outcome. And you can have smaller p values like p<0.01 = 99% which is even stronger evidence. But how does it work? Why does a calculation given you that certainty? And how was it decided that 0.05 is the point when the value becomes statistically significant? And to lead on from that, if there is a clear relationship between 2 variables, you have to ignore it if its only 90%.. Im just confused on the background of the of thr p value.

ELIF: How would we calculate where to go for space travel?	g1jul1	false	explainlikeimfive	Mathematics	Let's say we want to go to Alpha Centauri A and it's about 4.3 light-years away. So, The information about where the star is is almost four and a half years old by the time we get it. Given that the star itself is moving through space, if we went just where we saw it last from here, by the time a ship got there, it would be gone right? How would we figure out what direction it went and how to rendezvous with it?

eli5, How do you do something for Pi seconds? How does that work? [Scenario below]

jso8jz

false

explainlikeimfive

Mathematics

What would happen if someone tried to do something for Pi seconds? I created this scenario in my head earlier today and I feel that there is definitely something I’m missing because the answer seems like it should be easy but i can’t seem to find it. Say that Person 1 (P1) Takes exactly 3 seconds to do a push-up, P2 takes exactly 3.5 seconds to do a push-up, and P3 takes Pi seconds to do a push-up. P1 would finish the push-up first, P3 second, and P2 last. This is obvious, since the numbers (3, ~3.14, 3.5) work easily that way. To an onlooker, it’s clear the order in which the push-ups were finished. But, seeing as though Pi never ends, how does P3 ever finish their push-up? In one way of thinking, isn’t it fair to say that, to a microscopic level, they never finish their push-up? The number of seconds it takes for them to finish it is so small, to some degree, they will never complete the task? But, we already know that they complete the task because Pi is between 3 and 3.5, and P1 and P2 already finished theirs, and so P3 must’ve, logically, finished theirs as well? Please don’t roast me to oblivion, I’m honestly looking for an answer that makes sense. Thank you! x

With respect to my background, I have just completed my high school with a knowledge of basic differential and integral calculus; I am nevertheless seeking to cultivate an interest in pure mathematics.

While the name does sound pretty fascinating, I hope to find a good explanation regarding this topic. Thanks in advance !

ELI5: What do odds mean in gambling and how are they calculated?

I saw a post on gambling odds regarding who killed Mr. Burns, but I have no clue what all that actually means.

Is ten to one odds the same as 10/1 odds? How can different people bet different odds on the same gamble (as seen with the post, Homer seeing really low odds and Maggie getting like 70/1)?

I am in a music composers circle and here is the latest instructions, by a composer whose compositions are great but English is not: “The challenge is to invent a soundtrack or soundscape for a movie or a novel that tells the story of the Tribe of Borel. The language of this people is essentially mathematical demonstrations. The onlu imposed figure is that the first 8 bars of your track are identical to the last 8 . No duration limit. Play as you like with spirit of a collage. I think you can find mathematical demonstrations in different languages on youtube. But there are probably other ways to express this mathematical dimension. I hope you will enjoy it ! https://en.wikipedia.org/wiki/Borel_set" This guy is a great composer so i want to wrap my mind around this. Any ideas?

EDIT: I am maybe being unclear. I'm referring to the paper side-on once folded. What I mean is that if you roll a sheet of paper into a tube shape, the end of it is a circle (360 degrees). But if you fold the edges into a triangle at the edge, then that's only 180 degrees but it's the same bit of paper.

But how is the difficulty here actually adjusted? What is the program doing or not doing when it’s playing to win, versus going easy on you? Thanks!

ELI5: Where does the p value come from?

dus64i

false

explainlikeimfive

Mathematics

So i know the value needs to be 'satistically significant' for an experiment to be valid and that the variable chosen is explaining the outcome. I also know it needs to be p<0.05 so you know it's above the 95% confidence interval and that the value chosen is explaining the outcome. And you can have smaller p values like p<0.01 = 99% which is even stronger evidence. But how does it work? Why does a calculation given you that certainty? And how was it decided that 0.05 is the point when the value becomes statistically significant? And to lead on from that, if there is a clear relationship between 2 variables, you have to ignore it if its only 90%.. Im just confused on the background of the of thr p value.
