Mathematics is about wonder, creativity and fun, so let's teach it that wayAlice in Wonderland enthusiasts recently celebrated the story's anniversary with creative events like playing with puzzles and time—and future Alice exhibits are in the works. The original 1865 children's book Alice's Adventures in Wonderland, sprung from a mathematician's imagination, continues to inspire exploration and fun.

Mathematics Education Thu, 18 Jul 2019 09:50:01 EDTnews482659186Illusive patterns in math explained by ideas in physicsPatterns appear widely throughout nature and math, from the Fibonacci spirals of sea shells to the periodicity of crystals. But certain math problems can sometimes trick the human solver into seeing a pattern, but then, out of the blue, the pattern suddenly disappears. These illusive patterns crop up in many areas of math, with one example coming from certain calculus integrals that have deceived the intuition of even the best mathematicians.

Mathematics Thu, 18 Jul 2019 06:00:01 EDTnews482637571Ramanujan machine automatically generates conjectures for fundamental constantsA team of researchers at the Israel Institute of Technology has built what they describe as a Ramanujan machine—a device that automatically generates conjectures (mathematical statements that are proposed as true statements) for fundamental constants. They have written a paper describing their device and have uploaded it to the arXiv preprint server. They have also created a webpage for people who wish to allow the network to use their computer's process cycles, suggest a proof or develop code toward new mathematical structures.

It appears to have finally met its match through work by Hao Huang, an assistant professor of mathematics at Emory University.

Mathematics Wed, 10 Jul 2019 08:59:25 EDTnews481967944Expert mathematicians stumped by simple subtractionsMathematical thought is seen as the pinnacle of abstract thinking. But are we capable of filtering out our knowledge about the world to prevent it from interfering with our calculations? Researchers from the University of Geneva (UNIGE), Switzerland, and the University of Bourgogne Franche-Comté, France, have demonstrated that our ability to solve mathematical problems is influenced by non-mathematical knowledge, which often results in mistakes. The findings, published in Psychonomic Bulletin & Review, indicate that high-level mathematicians can be duped by some aspects of their knowledge about the world and fail to solve primary school-level subtraction problems. It follows that this bias needs to be factored into the way mathematics is taught.

Mathematics Tue, 18 Jun 2019 07:14:46 EDTnews480060876The hidden structure of the periodic systemThe periodic table of elements that most chemistry books depict is only one special case. This tabular overview of the chemical elements, which goes back to Dmitri Mendeleev and Lothar Meyer and the approaches of other chemists to organize the elements, involve different forms of representation of a hidden structure of the chemical elements. This is the conclusion reached by researchers at the Max Planck Institute for Mathematics in the Sciences in Leipzig and the University of Leipzig in a recent paper. The mathematical approach of the Leipzig scientists is very general and can provide many different periodic systems depending on the principle of order and classification—not only for chemistry, but also for many other fields of knowledge.

The continuous gentle, wavy hills and wide valleys of the Carpathians, Appalachians or lower parts of the Alps contrast strongly with the soaring peaks, ragged ridges and deep ravines of the high Tatra mountains and Pyrenees, which are, in turn, different from the inaccessible, snow-covered Himalayan or Andean giants, along whose slopes flow long tongues of glaciers instead of water. Beneath this great diversity, however, lies a surprisingly similar structure.

But when both numbers have a billion digits each, that means a billion times a billion or 1018 operations.
