Statistica Online Textbook "Thank you and thank you again for providing a complete, well-structured, and easy-to-understand online resource. Every other website or snobbish research paper has not deigned to explain things in words consisting of less than four syllables. I was tossed to and fro like a man holding on to a frail plank that he calls his determination until I came across your electronic textbook...You have cleared the air for me.

factoids > googol / googolplex Words of wisdom are spoken by children at least as often as by scientists. The name 'googol' was invented by a child (Dr Kasner's nine-year-old nephew) who was asked to think up a name for a very big number, namely, 1 with a hundred zeros after it. He was very certain that this number was not infinite, and therefore equally certain that it had to have a name. At the same time that he suggested 'googol' he gave a name for a still larger number: 'Googolplex'. A googolplex is much larger than a googol, but is still finite, as the inventor of the name was quick to point out.

User:FreeT/Physics Equations Please do not edit this page. This is part of FreeT's space to type thoughts to use for a later time, giving a higher quality to the finished article. This subpage is about physics equations on the Irish Leaving Certificate sylabus. You may of course copy material from here, just please don't edit it. If you can come up with some good mnemonics, please enter them. *Edit* From the 2010 Leaving Certificate on, new log tables will be supplied for the exams which will include most of the following formulae.

Game Theory First published Sat Jan 25, 1997; substantive revision Wed May 5, 2010 Game theory is the study of the ways in which strategic interactions among economic agents produce outcomes with respect to the preferences (or utilities) of those agents, where the outcomes in question might have been intended by none of the agents. The meaning of this statement will not be clear to the non-expert until each of the italicized words and phrases has been explained and featured in some examples.

Mean, Median, Mode, and Range Purplemath Mean, median, and mode are three kinds of "averages". There are many "averages" in statistics, but these are, I think, the three most common, and are certainly the three you are most likely to encounter in your pre-statistics courses, if the topic comes up at all. The "mean" is the "average" you're used to, where you add up all the numbers and then divide by the number of numbers.

factoids > big numbers Numbers go on for ever, but our notation does not. If you want to write down the value of a very big number (way bigger even than a googolplex ), the mathematical notations for factorial or exponentiation, the fastest growing 'conventional' functions, eventually becomes unweildy; you get too many factorials or exponents to manipulate easily. Something more extensible is needed. The so-called "large primes " -- useful for cryptography -- are relatively small compared to the kind of numbers that soon arise in these notations. Knuth's up-arrow notation In 1976 Donald Knuth published his up-arrow notation for large numbers. 13 Useful Math Cheat Sheets Posted by Antonio Cangiano in Applied Math, Math Education, Software, Tutorial on September 20th, 2008 | 38 responses Cheat sheets can be very useful and make for great posters around your room. The following is a collection of 13 cheat sheets for several mathematical topics and programs: And since most of us like to show our math pride off when out and about as well, Amazon sells this awesome Math Cheat Sheet T-shirt with formulas on both sides (Also available for Science and Engineering).

Quoting, Paraphrasing & Summarising A summary is an overview of a text. The main idea is given, but details, examples and formalities are left out. Used with longer texts, the main aim of summarising is to reduce or condense a text to it's most important ideas. Summarising is a useful skill for making notes from readings and in lectures, writing an abstract/synopsis and incorporating material in assignments. How to summarise Calculating the Distance to the Horizon For Any Game Home Up Site Map Assumptions | Method 1 | Method 2 Method 1 | Method 2 This is all based on the assumption that the horizon is the point on the world's surface at which the line of sight of the viewer, whatever their height, becomes parallel (tangential) to the surface of the world, and meets the surface of the world (so that the viewer cannot see any further than it).
