South African students study math via cell phone

The Associated Press reported on Thursday about an unusual experiment occurring out of necessity in South Africa. With students preparing for required graduation exit exams just less than a month a way, droves of them are turning for MXit, a popular instant messaging service, for assistance. Specifically, the students are using MXit to get answers to their math questions. Tutoring by cell phone was made necessary following a nationwide strike of South African teachers just before the all important exams.

Facebook-Ally in math education?

The Hill is reporting that on Thursday math students and educators gained a new ally in the quest for better math education in America–Facebook.  On Thursday, the popular social networking site sent a letter to Congressional leaders asking for more funding for math, science, and technology education, expressing concerns that if action isn’t taken, America will fall behind its competitors in these key areas. Excerpts from the letter follow: The shortage of students entering STEM careers has long been recognized in Washington, Silicon Valley, and beyond.

Lyric probability processor

Since the first electronic computers were developed over 60 years ago, they have operated in a fundamentally similar way. Lyric Semiconductor recently announced a new kind of computer processor that is a shocking change in the math behind computers. You may know that computers “speak” binary, meaning that at a fundamental level, they operate on the base two number system, a series of 0’s and 1’s. The reason for this is that those 0’s and 1’s can be easily translated into what sort of amounts to a long list of yes/no or true/false questions for the computer to crunch.

New pi world record

All hail Shigeru Kondo, the new king of pi! According to The Daily Telegraph, Mr. Kondo, a systems enginer, has broken the world record for the most digits calculated of pi, finding the ratio of a circle’s circumference to diameter to a mind-blowing 5 trillion places. For those unfamiliar with pi, it is an irrational number, meaning that when expressed in decimal form, its decimal continues forever without ever reaching a repeating pattern.

Calculator Spy Camera

Here’s a gadget that we didn’t see coming: a calculator that doubles as a spy camera. If you’d like to keep tabs on anyone from your babysitter to your colleagues, this device delivers. The calculator copies the design and functionality of a Casio DS-5500, so it is a usable calculator. It records at 640 x 480 resolution at 30 frames/second. Apparently, it can also take 1280 x 960 pictures, for those of you that plan to use it as a replacement for your digital SLR.

Million Dollar question: Does P = NP?

In an age where we are surrounded by computers that solve problems of almost unimaginable complexity in a matter of seconds, students of math may be surprised to learn that there is an entire category of problems generally believed to be “unsolvable” by computers.  The class of P problems can be solved in “polynomial time,” while NP problems are solved in “nondeterministic polynomial time.” At the risk of oversimplifying, P problems can be solved by a computer fairly quickly.
