THEREMIN - A Touch Friendly Synthesizer ✖Update: 7 February 2014 Thanks to everyone for sharing! Over 100,000 people have played on the theremin in the last 3 days which is absolutely amazing. Due to a large number of requests, we've began working on a record function as well as an offline version of the app which will be available soon. Feel free to either subscribe at the bottom of the page or follow us on Facebook & Twitter for updates and future toys. More info The web audio theremin is a touch friendly & responsive audio synthesizer built in javascript using the Web Audio API with HTML5 canvas. Feel free to get in contact with me here: luke@femurdesign.com If you are using Safari or Chrome, please update your browser to the latest version. This synthesizer uses latest Web Audio API technology which is currently supported in Chrome, Safari, Opera and iOS Safari 6+.
Ding Dong Bell The sound of bells In East Anglia, as you look across the fens, villages appear almost like little islands (indeed some of them were islands before the fens were drained) and these villages are dominated by big churches with tall towers. In the past people regulated their lives and passed messages by ringing church bells, which could be heard for miles around, telling the time of day, and giving news of births, marriages and deaths in a parish. Bell ringing is good exercise for the body and mind, the bells are heavy and the bellringers have to remember the changes. The mathematics of the changes With four bells there are of course many more possibilities; there are twenty four different permutations or orders in which the bells can be rung and there are four bell ringing changes. Now look at the network diagram below which shows all 24 possible permutations in the order of the four bells. Find the vertex labelled 1234. Circuit diagram showing the 24 permutations of 4 bells
20 Random Amazing Facts MISHELLA / Shutterstock.com Northfoto / Shutterstock.com Text Version: Fact 556: A popular additive to many perfumes, Ambergris, comes from the intestines of sperm whales. When it’s fresh, not surprisingly, it smells like crap, but then later begins to smell sweet and “earthy”. Fact 557:Jumping Badger was the birth name of famed Indian chief Sitting Bull… His father’s name was Jumping Bull and his mother’s was “Her-Holy-Door”. Fact 558: Famed Astronaut Buzz Aldrin’s mother’s name, before getting married, was Marion Moon. Fact 559: The “Sea of Tranquility” was the location on the Moon where man first set foot. Fact 560: Unlike Earth and most other planets in our solar system, Venus rotates clockwise. Fact 561: You are 10,000 times less likely to be killed by a shark than as the result of either texting and driving yourself, or someone else doing it. Fact 562: Birth control pills meant for human women also work on gorilla females. Fact 563: Mother in law is an anagram for “Hitler Woman”.
Monte Carlo method Monte Carlo methods (or Monte Carlo experiments) are a broad class of computational algorithms that rely on repeated random sampling to obtain numerical results; typically one runs simulations many times over in order to obtain the distribution of an unknown probabilistic entity. They are often used in physical and mathematical problems and are most useful when it is difficult or impossible to obtain a closed-form expression, or infeasible to apply a deterministic algorithm. Monte Carlo methods are mainly used in three distinct problem classes: optimization, numerical integration and generation of draws from a probability distribution. The modern version of the Monte Carlo method was invented in the late 1940s by Stanislaw Ulam, while he was working on nuclear weapons projects at the Los Alamos National Laboratory. Immediately after Ulam's breakthrough, John von Neumann understood its importance and programmed the ENIAC computer to carry out Monte Carlo calculations. Introduction[edit]
Body Language By a man’s fingernails, by his coat-sleeve, by his boots, by his trouser-knees, by the calluses of his forefinger and thumb, by his expression, by his shirt-cuffs, by his movements – by each of these things a man’s calling is plainly revealed. That all united should fail to enlighten the competent enquirer in any case is almost inconceivable / Sherlock Holmes, 1892. The aim of this exhibition is — to become aware of ourselves and of the people around us. Source: wondersbook.wordpress.com Copyright © wondersbook.wordpress.com .

Dr Hannah Fry: the mathematical models that underpin our sexual success | Science What are the odds? Or how mathematician Peter Backus weighed up his chances of finding love… Just as it’s not possible to calculate precisely how many alien life forms there are, it’s also not possible to calculate exactly how many potential partners you may have. But all the same, being able to estimate quantities that you have no hope of verifying is an important skill for any scientist. It also applies to maths student Peter Backus’s well-publicised quest to see whether there were intelligent, socially advanced women of the same species out there for him to date. 1. 2. 3. 4. 5. 6. 7. Leaving him with just 26 women in the whole world he would be willing to date. Personally, I think that he is being a little picky. I think there’s room to be a bit more generous. 1. 5. 6. 7. Almost a thousand potential partners across a city, then. But there is another issue. Strangely though, opening our minds to all potential partners seems to be the opposite of what we do when we’re single.
