the problem you brought up Notorious about the children kind of remind me of the two dice problem, and what sum would appear the most http://gwydir.demon.co.uk/jo/probability/calcdice.htm

Share Bear posted:im gonna frantically search for a proof for e that does not involve calculus, but i feel like this is something that is done inductively the way its proven to most people is through compounded interest, $e is the amount of money youll get starting with $1 and 100%/yr interest, compounded continuously over a year. strictly speaking its a limit but you can get the point across just fine to somebody who doesnt understand limits

theres also the definition that e is the sum for n=0..infinity of 1/n!

tbh, this is why there should be a financial literacy class as a separate thing among other reasons so you can present e as part of the magic spell that banks will use to hose you over

Couldn't you give people a primer on compound interest in a non-technical way as part of their high school education? Make it sort of like a sex education. They'd benefit from knowing about about predatory lending practices like ARMs and such. I don't see much benefit from people having a vague recollection of the natural logarithm and exponential growth, when really what they need to know is how to protect themselves from banks taking advantage of them. How to find an appropriate interest rate calculator and use it would be enough (although using search effectively seems to be non-trivial for a lot of people).

augh i still dont get this loving algorithm and ive emailed the authors weeks ago but they dont write me back  ive done the first part where i segment an image into vertical zones, and segment the zones into regions. then comes a HMM part where im supposed to refine the zones, but the way its described is impenetrable for me. i would be really gratful if someone could help me out here problem in detail: http://math.stackexchange.com/questions/955964/hidden-markov-model-transition-probabilities-which-are-modeled-with-an-exponent papers (all describe same algorithm): 2008 - ILSP - Robust text-line and word segmentation for handwritten documents images.pdf 2009 - ILSP - Handwritten document image segmentation into text lines and words.pdf 2011 - ILSP - Segmentation of Handwritten Document Images into Text Lines.pdf 2013 Segmentation of heterogeneous document images - an approach based on machine learning, connected components, and texture analysis.pdf (section 5.2) Carthag Tuek fucked around with this message at 02:36 on Oct 30, 2014 |

stats lets you understand such fundamental things about how the world works, on a physical level, and makes clear that some things seem like common sense but aren't etc

when doing uni physics i was doing a tutorial thing coz i was 26 and hadnt done maths since 16 and he stopped the class to go over all these algrebra fundamentals, like how you can flip both sides of equation or thatn division by X was the same as multiplation by 1/X and all of a sudden algebra became not hard but simply a puzzle to be solved and a powerful tool for getting information how you wanted it and it also lets you "see inside" a lot of physical phenonmena, and skippingf it would be a tradegy
