## New ActivityThe latest activity to be updated on this site is called "Perpendicular Pairs" (Find the pairs of equations that will produce perpendicular graphs.). So far this activity has been accessed 78 times and 15 people have earned a Transum Trophy for completing it. ## Recent News:## How cells correct errors under time pressureHow does a cell balance risk and speed when dividing? Scientists have developed and experimentally tested the first mathematical theory that describes the cell's best strategy for dividing safely and efficiently. more... ## An easier way to teach robots new skillsResearchers have developed a technique that enables a robot to learn a new pick-and-place task with only a handful of human demonstrations. This could allow a human to reprogram a robot to grasp never-before-seen objects, presented in random poses, in about 15 minutes. more... ## Study shows simple, computationally-light model can simulate complex brain cell responsesStudying how brain cells respond to signals from their neighbors can aid the understanding of cognition and development. However, experimentally measuring the brain's activity is complicated. Neuron models provide a non-invasive way to investigate the brain, but most existing models are either computationally intensive or cannot model complex neuronal responses. Recently, a team has used a computationally simple neuron model to simulate some of the complex responses of neurons. more... ## Tear-free hair brushing? All you need is mathScientists explore the mathematics of combing and explain why the brushing technique used by so many is the most effective method to detangle a bundle of fibers. more... ## Rational neural network advances machine-human discoveryMath is the language of the physical world, and some see mathematical patterns everywhere: in weather, in the way soundwaves move, and even in the spots or stripes zebra fish develop in embryos. more... ## Quantum information theory: Quantum complexity grows linearly for an exponentially long timePhysicists know about the huge chasm between quantum physics and the theory of gravity. However, in recent decades, theoretical physics has provided some plausible conjecture to bridge this gap and to describe the behavior of complex quantum many-body systems -- for example, black holes and wormholes in the universe. Now, researchers have proven a mathematical conjecture about the behavior of complexity in such systems, increasing the viability of this bridge. more... ## Chaos theory provides hints for controlling the weatherResearchers have used computer simulations to show that weather phenomena such as sudden downpours could potentially be modified by making small adjustments to certain variables in the weather system. They did this by taking advantage of a system known as a 'butterfly attractor' in chaos theory, where a system can have one of two states -- like the wings of a butterfly -- and that it switches back and forth between the two states depending on small changes in certain conditions. more... | Tweets by @Transum |
