P.R.Halmos, How to Write MathematicsAMS, 1973 Also, some pages are organized into series while others, especially the older ones, are accessible individually. Throughout the discussions at this site I refer to various titles I love and find useful enough to have them in my own library. First off, you may want to look at the page that explains to the curious the origin and nature of my logo. There is also a page where I offer a beautiful geometric problem. One page currently presents 118 different proofs of the Pythagorean Theorem which was a great fun putting together. Another page looks into different ways a specific statement may be related to a more general one. Other pages have educational content. To me Internet is one of life's wonders. Recently I discovered the source of the 4 Travelers problem. |Contents||Store|

Algebra: Themes, Tools, Concepts - Henri Picciotto matematika.ba Lucia de B. is innocent This internet site has been created by a group of individuals who form the “Committee for Lucia”. None of its members are related to Lucia, nor are they from her circle of friends. They are merely individuals driven by the certainty that Lucia is the victim of a gross miscarriage of justice. # News: BBC 23-7-2010 – Can chance make you a killer?

Math Delights - Coins in Twoland by Joshua Zucker, joshua.zucker at stanfordalumni dot org In Twoland, the only coins are the toonies: 1, 2, 4, 8, 16, 32, 64, 128, and so on. The law says you must always pay with exact change; only the banks are allowed to make change. In Twoville you must pay with zero, one, or two of each type of coin, never more than two. (If Twoville is too complicated for you, try Oneville where you can only pay with zero or one of each coin!) For instance, to pay 6 toonies, you could pay with: one 4 and one 2 (and zero 1s) one 4, zero 2s, and two 1s or two 2s and two 1s. You could describe the three legal ways to pay by writing them in English, as I just did. Another, shorter way to write the list of legal ways to pay might be like this: 110102 022 (or simply 22). Create a table with the list of ways to legally pay for items that cost 1 toonie, 2 tonnies, ..., 16 toonies in Twoville, remembering that you cannot use more than two of each coin. What about the amounts that are exactly one single coin?

Matematička takmičenja u Srbiji Can Math Make a Better Marathon? Less than two miles from the finish of last month’s Chicago Marathon, with the race finally narrowed to a neck-and-neck duel between two Kenyan runners, the NBC television commentators began placing their bets. It wasn’t a hard call. Abel Kirui, who hadn’t won a marathon since 2011, was visibly struggling, repeatedly falling behind and then clawing his way back. At one point, grimacing, he snatched a cup of water from a volunteer and dumped it over his head. Such moments are what make marathons fascinating to watch and their results impossible to predict. In theory, the pace that a runner can sustain in a marathon is a straightforward function of physiology—how well the heart can pump fresh blood through the arteries, how much energy the leg muscles burn, and so on. Noakes is now most famous for having abandoned the idea of physiological limits entirely. At the moment, the clearest example of the potential impact of real-time data comes from cycling.
