Pedro Matias Sets New Texting Record At Mobile World Cup 70

Pedro Matias showed off his mad txtin sklz at this year's Mobile World Cup and managed to set a new record for "fastest, most accurate" texts as determined by the event's corporate owners. "history was made when Portugal's Pedro Matias set the new World's Record for texting by typing a 264-character text in just 1 minute 59 seconds (besting the previous record by 23 seconds). Of course, each Mobile World Cup must have its share of controversy -- in this case, Engadget Mobile's very own Chris Ziegler led a silent protest during the awards ceremony. The group was reportedly upset over the use of QWERTY phones (the LG enV3 in this case) to break the record."

The Perfect Way To Slice a Pizza 282

iamapizza writes "New Scientist reports on the quest of two math boffins for the perfect way to slice a pizza. It's an interesting and in-depth article; 'The problem that bothered them was this. Suppose the harried waiter cuts the pizza off-center, but with all the edge-to-edge cuts crossing at a single point, and with the same angle between adjacent cuts. The off-center cuts mean the slices will not all be the same size, so if two people take turns to take neighboring slices, will they get equal shares by the time they have gone right round the pizza — and if not, who will get more?' This is useful, of course, if you're familiar with the concept of 'sharing' a pizza."

Super-Earths Discovered Orbiting Nearby, Sun-Like Star 242

likuidkewl writes "Two super-earths, 5 and 7.5 times the size of our home, were found to be orbiting 61 Virginis a mere 28 light years away. 'These detections indicate that low-mass planets are quite common around nearby stars. The discovery of potentially habitable nearby worlds may be just a few years away,' said Steven Vogt, a professor of astronomy and astrophysics at UCSC. Among hundreds of our nearest stellar neighbors, 61 Vir stands out as being the most nearly similar to the Sun in terms of age, mass, and other essential properties."

Jetman Attempts Intercontinental Flight 140

from the a-jetwing-and-a-prayer dept.
Last year we ran the story of Yves Rossy and his DIY jetwings. Yves spent $190,000 and countless hours building a set of jet-powered wings which he used to cross the English Channel. Rossy's next goal is to cross the Strait of Gibraltar, from Tangier in Morocco and Tarifa on the southwestern tip of Spain. From the article: "Using a four-cylinder jet pack and carbon fibre wings spanning over 8ft, he will jump out of a plane at 6,500 ft and cruise at 130 mph until he reaches the Spanish coast, when he will parachute to earth." Update 18:57 GMT: mytrip writes: "Yves Rossy took off from Tangiers but five minutes into an expected 15-minute flight he was obliged to ditch into the wind-swept waters."

+ - Israel Gelfand Dies at 96->

Submitted by tehgnome
tehgnome (947555) writes "Arguably the greatest mathematician of the 20th century has passed at the age of 96. The wake of Gelfand's work has influenced every modern branch of mathematics from Representation theory and Fourier analysis, to Algebraic Geometry. He will be remembered for his extreme influence on the world of mathematics and his legendary Gelfand seminar."

I think you make a nice point, but most of all I think you slipped in a better idea. Set Theory. A good class in set theory and introduction to finite math and proofs would be the best. I am a graduate student in mathematics, and I see many math majors without a good background in set theory. Also, getting an early start with induction and simple proofs in combinatorics builds mathematical maturity very quickly. Additionally, it is easy to get students interested in combinatorics because the problems are so easy to understand and fun once you do. Obvious Halmos' Naive Set theory is the one of the standards. For introduction to combinatorics, the book by Jonsenbaugh is pretty easy and it covers and intro to proof. I really like the combinatorics book by Brualdi but it might be a bit difficult. If you are super brave you could read the book by Lawvere on an introduction to category theory...
