Tackle this logisticians’ parlour game and you may be a bit closer to understanding the nature of truth itself

“Three gods A, B, and C are called, in some order, True, False, and Random. True always speaks truly, False always speaks falsely, but whether Random speaks truly or falsely is a completely random matter. Your task is to determine the identities of A, B, and C by asking three yes-no questions; each question must be put to exactly one god. The gods understand English, but will answer all questions in their own language in which the words for ‘yes’ and ‘no’ are ‘da’ and ‘ja’, in some order. You do not know which word means which.” Welcome to the “Hardest Logic Puzzle Ever”. If you should happen upon three questions that will unmask the gods, don’t stop there. Your next task: make the puzzle even harder.

“I never am really satisfied that I understand anything; because, understand it well as I may, my comprehension can only be an infinitesimal fraction of all I want to understand about the many connections and relations which occur to me, how the matter in question was first thought of or arrived at…”

Thanks for the beautiful submission

Ada Lovelace has been honoured by a Google doodle on the 197th anniversary of her birth. Photograph: Google Google’s latest doodle celebrates the 197th birthday of Ada Lovelace, the 19th century mathematician and daughter of romantic poet Lord Byron. Often described as world’s first computer programmer, Lovelace showed a keen interst in mathematical studies from an early age and was taught by her mother, Annabella, who was also a gifted mathematician. In correspondence with Charles Babbage, who was working on the ideas for a machine that is now recognised as a forerunner of the modern computer, Ada demonstrated her gift for mathematics and was described by him as ‘the enchantress of numbers’. She was introduced to him by another female scientist famous in her day, the mathematician Mary Somerville, who mentored Ada during her relatively short life. Babbage was impressed by the mathematical skills Ada possessed and invited her to translate a piece in Italian written by Luigi Menabrea describing Babbage’s ‘analytical engine’, so that it could be published in England. Her notes include what is recognised as the first algorithm intended to be processed by a machine, while she also speculated on its future ability to create graphics and complex music. Born in 1815, she had no relationship with her father, who died when she was eight. In 1835, she married William King, who was created Earl of Lovelace in 1838. She died in 1852 at the age of 36. Her lasting legacy as role model for girls and young women considering careers in technology is remembered on Ada Lovelace Day, which is dedicated to the celebration of the achievements of women in science and technology.

No one knows where it came from, or what it was meant to do, but 4 percent of all trading in the U.S. stock market last week was executed by one algorithm, CNBC reports. Nanex, a market data firm, told CNBC that the algorithm was placing orders once every 25 milliseconds and then canceling them. The orders went out in bursts of 200, then 400, and then 1,000 orders. Then suddenly, around 10:30 AM on Friday, the algorithm stopped entirely. Nanex has the animation that helped them zoom in to the mysterious algorithm posted here. So why would someone put out fake orders like this? A trader explained to us that this is a high frequency trading firm’s way of baiting buyers interested in purchasing a specific stock and forcing them to reveal their positions. Once the potential buyer has put out their bid, the HFT cancels the order and the buyer is left out in the open. Usually, its a set-up for another trading strategy the HFT is about to execute. Tricky. (via Mystery Algorithm 4% Of Trading Last Week – Business Insider)

PROOFS are the currency of mathematics, but Srinivasa Ramanujan, one of the all-time great mathematicians, often managed to skip them. Now a proof has been found for a connection that he seemed to mysteriously intuit between two types of mathematical function. The proof deepens the intrigue surrounding the workings of Ramanujan’s enigmatic mind. It may also help physicists learn more about black holes – even though these objects were virtually unknown during the Indian mathematician’s lifetime. Born in 1887 in Erode, Tamil Nadu, Ramanujan was self-taught and worked in almost complete isolation from the mathematical community of his time. Described as a raw genius, he independently rediscovered many existing results, as well as making his own unique contributions, believing his inspiration came from the Hindu goddess Namagiri. But he is also known for his unusual style, often leaping from insight to insight without formally proving the logical steps in between. “His ideas as to what constituted a mathematical proof were of the most shadowy description,” said G. H.Hardy (pictured, far right), Ramanujan’s mentor and one of his few collaborators. (via Mathematical proof reveals magic of Ramanujan’s genius – physics-math – 08 November 2012 – New Scientist)

A Washington State University researcher has found that engaging elementary school students in science for as little as 10 hours a year can lead to improved test scores in math and language arts. Samantha Gizerian, a clinical assistant professor in WSU’s Department of Veterinary and Comparative Anatomy, Pharmacology and Physiology, saw improved test scores among fourth-grade students in South Los Angeles after students from the Charles R. Drew University of Medicine and Science gave 10 one-hour presentations on science. “A lot of students say things like, ‘I didn’t know science was fun,’” says Gizerian, who helped with the classes while on the Drew faculty. “And because they think it’s fun, all of a sudden it’s not work anymore. It’s not homework. It’s not something extra that they have to do.” The fourth-graders in turn took home nonfiction books and showed a greater willingness to practice reading and math, says Gizerian. Test scores bear that out.

A little science goes a long way: Math and language scores improve with 10 hours of instruction

A must watch:

Jacob Barnett is an American mathematician and child prodigy. At 8 years old, Jacob began sneaking into the back of college lectures at IUPUI. After being diagnosed with autism since the age of two and placed in his school’s special ed. program, Jacob’s teachers and doctors were astonished to learn he was able to teach calculus to college students.

At age nine, while playing with shapes, Jacob built a series of mathematical models that expanded Einstein’s field of relativity. A professor at Princeton reviewed his work and confirmed that it was groundbreaking and could someday result in a Nobel Prize. At age 10, Jacob was formally accepted to the University as a full-time college student and went straight into a paid research position in the field of condensed matter physics. For his original work in this field, Jacob set a record, becoming the world’s youngest astrophysics researcher. His paper was subsequently accepted for publication by Physical Review A, a scientific journal shared on sites such as NASA, the Smithsonian, and Harvard’s webpage. Jacob’s work aims to help improve the way light travels in technology.

Jacob is also CEO and founder of Wheel LLC, a business he started in his mom’s garage, and is in the process of writing a book to help end “math phobia” in his generation.

Jacob’s favorite pastime is playing basketball with the kids at his charity, Jacob’s Place. It is a place where kids with autism are inspired every day to be their true authentic selves…just like Jacob.
