...rare as you might think. Affecting some 2.5-7.5% of the population, researchers say, the learning disability dyscalculia prevents people from comprehending or manipulating numbers, even small ones, easily. Though you may have never heard of it, the condition is much more than being bad at math. "You need to hear people suffering from dyscalculia, how hard it is for them to do everyday things, just going to the shop, counting change," says Roi Cohen Kadosh, a research fellow at University College London (UCL). Other practical impossibilities for dyscalculics: balancing a checkbook, planning for retirement, being a baseball...
Cohen Kadosh took five volunteers with normal math abilities through more than 500 trials. In an experiment published this month in Current Biology, he targeted different regions of the test subjects' brains with magnetic pulses while they performed number-recognition problems. A normal subject, when asked to identify whether a 2 or a 4 is written in larger text, will be a split-second faster on those occasions that the 4 is printed bigger. Normal subjects process that 4 is a bigger quantity than 2, and that information aids their pick - just as number recognition slows them down slightly when...
...tantalizing possibility that one day a cure may be as simple as flicking that switch in reverse. Cohen Kadosh hopes the result will allow scientists to develop a diagnostic tool for dyscalculia based on neuroimaging. Identifying children with developmental dyscalculia would let parents intervene earlier to teach important math concepts, just as they can intervene today to help dyslexic children read better...
...Farm” is mostly gloomy and almost always hilarious in its take on the absurd, whether that’s education, religion, or war. In 57 sketches that can be read in under a minute each, Rich finds humor amid the darkest of scenarios: a lonely math teacher’s test questions (“5. A math teacher is frightened 95% of the time. How many hours a day is he frightened? What is he so afraid of?”), a Crayola color-namer’s recent colors (“Sad Red?...
Einstein's exposure to science and math produced a sudden transformation at age 12, just as he would have been readying for a bar mitzvah. He suddenly gave up Judaism. That decision does not appear to have been drawn from Bernstein's books because the author made clear he saw no contradiction between science and religion. As he put it, "The religious inclination lies in the dim consciousness that dwells in humans that all nature, including the humans in it, is in no way an accidental game, but a work of lawfulness that there is a fundamental cause...
