The Perfect Way To Slice a Pizza 282

Posted by samzenpus from the equal-distribution-of-the-pie dept.
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."

i find its fairly naive to think that one will find a candidate that that they believe in 100%. With the number of ppl in the US and the quantity of ideas those ppl generate, finding a candidate that agrees with each one (even within their own party let say) is very slim. one needs to look at a candidate that has the ability to make a positive change toward a greater good. so you may disagree on one or even a handful of issues, but do you atleast agree with the way he/she forms their opinion and delivers his/her argument. because in the end, those handful of ideas you disagree with may be changed both in your mind and or his/hers. combine this with the fact that we also have congress/house/supreme court and the few things you don't like about the prospective president may not even matter.

to me obama is the first in a long time of presidential candidates that has the country's interest at heart and has an open enough mind to accept the changes that are and will be happening in this country.

First Fossil Evidence That Velociraptors Hunted in Packs 169

Posted by Zonk from the clever-girl dept.
Ponca City, We Love You writes "The New Scientist reports that palaeontologists have excavated a fossil trackway in Shandong Province in China 100 to 120 million years old that contains footprints left by six Dromeosaurs, the more formal name for raptors, showing evidence of group behavior. Up until now, the popular stereotype from Jurassic Park of raptors hunting in packs has had no fossil evidence to back it up. The paths of the six 90 kilo raptors do not overlap where the animals walked alongside a river or stream. '"The odds of these tracks being made by different individuals that just happen to be moving in the same direction, without their tracks stepping on one another, are small," said Jerry D. Harris, director of paleontology at Dixie State College. "Groups that do that usually have relatively sophisticated behavior, and they're relatively intelligent," Harris added. "By moving together in groups, it's entirely possible that they hunted in groups."'"

Research Reveals Mislaid Microprocessor Megahertz 99

ransom1982 noted a new article on The Register that says "Not only are chip companies regularly releasing ever-faster microprocessors, but new research has revealed that modern CPUs actually lose megahertz over time." This makes it even more complicated to compare the performance of Intel and AMD CPUs since you have differing architecture, clockspeeds AND the year of manufacture to consider. Buyer beware!

Chaos and Your Everyday Traffic Jam 477

Posted by timothy from the could-often-be-my-dad's-nutty-driving dept.
An anonymous reader writes "What causes these mysterious traffic jams that continually appear throughout the day for no reason whatsoever? Is it simply the fact that most people just don't have a clue how to drive? That's very possible, and in reality there are so many variables involved in something like a traffic jam. But is it possible that the entire traffic jam could be both the continuing and end result of a chain reaction set in motion by a single driver who was in too much of a hurry?"

Roomba + Wii remote + Perl = Awesome 175

Anonymous Wii Lov'n Coward writes "Check out the WiiRoomba, a mashup using a Wii remote, a perl script, and the Darwiin Remote software. While a little sluggish to respond, the Roomba is entirely controlled by the Wii remote accelerometers." All of the source code to do it yourself is available at the site linked, along with a youtube video of how it works.

The Physics of Santa 172

Posted by CmdrTaco from the tachyons-and-jeffries-tubes-oh-my dept.
Roland Piquepaille writes "If you don't believe that Santa Claus can deliver presents to millions of homes in a single night, Larry Silverberg, professor of mechanical and aerospace engineering at North Carolina State University (NCSU), explains that Santa's society of elves has an understanding of physics and engineering that exceeds our own. In fact, Santa Claus and his crew really can deliver presents in one night because of their advanced knowledge of electromagnetic waves, the space/time continuum, nanotechnology, genetic engineering and computer science. For example, he doesn't carry presents. He uses a nano-toymaker to fabricate toys grown atom by atom inside the children's homes. Very entertaining reading... Here is a link to additional details and pictures of Santa and his elves flying over New Zealand."
