ELI5: What's the difference between a point and a vector? | cl90wf | false | explainlikeimfive | Mathematics | This just won't get in my brain. If I'm in a 3d space and have a point, it has 3 values (xyz) that defines where in space it is. If I have a vector it also has 3 values to define where it is (or is headed which seems to be the same since at the end of it's arrow, it basically still has a point, that it's pointing at, right?). So what's the difference? |
ELI5: how do we measure the "number of gallons per second" a waterfall outputs | clbtlo | false | explainlikeimfive | Mathematics | For instance "Niagara Falls: 3,160 tons of water flows over Niagara Falls every second.

ELI5: Why the Fibonacci Sequence is important/ related to nature (and everything else) | 52hkpc | false | explainlikeimfive | Mathematics | I understand what it is and how it is broken down, but I can't quite seem to grasp how exactly it connects to nature and everything else. I looked at the other two, older posts, but it's just not clicking with me for some reason. Feel free to refer me to /r/nostupidquestions Edit: thank you all for your help & answers! It has finally clicked! |
ELI5: Wierdness of the binomial distribution | 52n21o | false | explainlikeimfive | Mathematics | Six heads out of ten coin tosses is a perfectly acceptable outcome. In my head, that would mean six hundred heads out of a thousand tosses is the same, but in fact, even getting 550 heads would mean there is 99% chance that the coin is unfair. How to grasp this concept? |

ELI5: What does an "over/under" mean in a gambling context? | 52x32d | false | explainlikeimfive | Mathematics | Someone in work today talked about the over/under of some team winning the sportsball and I realized I don't really understand what that means. Bonus points if you can explain how a "spread" works. (Is this the same thing?) As in for the Carolina Panthers v San Francisco 49ers game there is a 14.5 point spread in Carolina's favor (I think). |

ELI5: How many lines, shades, figures etc combination are in a given area of a paper or anywhere it's possible to write something down | 53tmzu | false | explainlikeimfive | Mathematics | It seems to me that lines on a piece of paper can be interpreted in a different way depending on how those lines are constructed, connected with each other. It's also fascinating to say that the famous mathematic equation E=Mc^2 could have existed, but are just waiting for Einstein to discover its existence. This includes basically everything humans ever have written or drawn on to something. So I just wanted to know the combination of this or is the answer infinite? |

ELI5: Excel Correlation Analysis: me vs. my boss | 4nwarc | false | explainlikeimfive | Mathematics | I work at a company that produces paper and the paper has to be measured by a density machine for quality purposes. Recently, the company has purchased a newer model of the density machine to replace the outdated one. My boss has given me the job to test the paper on both machines and compare the results in excel. The procedure is to obtain the sample and put in in the machine, which measures the density, and then put the SAME SAMPLE in the new machine. My problem is, with my knowledge of math, I should compare the two data sets on the y-axis and the sample number on the x-axis, in order to compare them against each other at the same sample number. He thinks the data set 1 should be on x-axis and data set 2 should be on y-axis. I feel like that can't be the case, considering that comparing x to x isn't a function, and graphs are just representations of functions (an input and an output). He thinks graphing two inputs should give a better correlation? Ex: His idea x/y = (98.2mm,96.2mm) My idea x/y1,y2 = (sample 1, 98.2mm, 96.2mm) I've taken much more calculus based courses(engineering) which may be the cause of my confusion, and lacking statistics Can someone else explain it better than he is to me? |

ELI5: Can anyone explain Kruskal's tree theorem or TREE(3)? | 4p51lu | false | explainlikeimfive | Mathematics | Been fascinated by large numbers such as Graham's number, but unlike Graham's number, which was reasonably easy to understand after going through some articles/explaination, TREE(3) is extremely hard to understand for me even after reading a couple of explanations. |
ELI5 the Cutting Stock Problem and ways we solve it. | 4p6zxe | false | explainlikeimfive | Mathematics | I received a really cool project at work that asks me to determine how many units of pre-cut material we use to make our fancy custom boxes. There's a lot of guess work involved sometimes and getting good at estimating supplies for these boxes takes a lot of experience (like I said, fancy ). In trying to develop a pretty algorithm for this project, I came across the Cutting Stock Problem. Maybe if I can see how algorithmic approaches to CSP are applied to two-dimensional supplies, it will help me finish my project and get a treat from the Big Boss. Thanks! Here's a video that address a problem similar to my own. |

ELI5: The Green (sometimes Blue) Eyed Prisoner (sometimes Islander)Problem | 4qjaer | false | explainlikeimfive | Mathematics | Here is a link detailing the problem in full. While the color and situation of the people may change, the logic behind it does not. The tl;dr of it is as follows: There are people in an isolated environment that may not speak about their eye color. If they find out about their eye color, they disappear (suicide, leave island on boat, killed by mind reader, etc). There are no reflective surfaces. All people in the environment have perfect logic. They can see each others eyes. Upon being told that at least 1 person has blue eyes, after x number of days where x is the number of blue eyed people in the environment, all the blue eyed people disappear. I just cannot find an explanation that doesn't leave me asking, "If they only know that at least one person has blue eyes, then how can they possible figure this out. How does watching the others' behaviors tell them that they know if somebody does or does not have blue eyes. If it were, "At least x - 1 people have blue eyes", I get it. But just 1? |

ELI5: Why does the distance between two points grow smaller as the observers distance from the two points grows larger? | 5clxhr | false | explainlikeimfive | Mathematics | The reason I have this under mathematics is because I believe this is more mathematics oriented, but I originally wondered this by just looking at a plane flying high and noticing how small the wingspan was -- I've never heard a rigorous definition of why this is how it is. |
