Langley’s Adventitious Angles - Wikipedia Langley’s Adventitious Angles Langley’s Adventitious Angles is a mathematical problem posed by Edward Mann Langley in the Mathematical Gazette in 1922.[1][2] The problem[edit] In its original form the problem was as follows: ABC is an isosceles triangle. Chaos theory A double rod pendulum animation showing chaotic behavior. Starting the pendulum from a slightly different initial condition would result in a completely different trajectory. The double rod pendulum is one of the simplest dynamical systems that has chaotic solutions. Chaos: When the present determines the future, but the approximate present does not approximately determine the future. Chaotic behavior can be observed in many natural systems, such as weather and climate.[6][7] This behavior can be studied through analysis of a chaotic mathematical model, or through analytical techniques such as recurrence plots and Poincaré maps.

Landing on a Comet, 317 Million Miles From Home Intended landing site Panorama by The New York Times Nov. 6 Comet 67P/C-G is shaped like a duck, with two lobes separated by a neck. Training on Signal Processing & Filter Design with MATLAB & SIMULINK Implementation Signal may be referred to as a function of time that conveys information about the behavior or characteristic of some physical phenomena. Examples of signal are temperature, voice, communication and geophysical among others. Signal can be acquired from its physical environment via sensors (e.g. microphone for voice acquisition). Scientists Uncover How Our Brains Recognize Faces GettyAlfred Pasieka/Science Photo Library When you see a face, what happens in your brain? How do your neurons process facial features to recognize a person you know? Thanks to a group of researchers at Caltech, we may finally have the answer. Doris Tsao

How Learning to Read Rewrites the Brain People who learn to read as adults show profound changes in deep structures of the brain, according to a new study. The findings may change researchers' perspectives on the extent of plasticity in the adult brain, the study said. In the study, researchers recruited a group of completely illiterate women from villages in northern India and taught them to read. The women also underwent brain scans, both before and after they learned to read.

Equality Challenge Unit Athena SWAN Charter ECU's Athena SWAN Charter Recognising advancement of gender equality: representation, progression and success for all. ECU’s Athena SWAN Charter was established in 2005 to encourage and recognise commitment to advancing the careers of women in science, technology, engineering, maths and medicine (STEMM) employment in higher education and research. Creating Narrow Reflections Basic Lighting A good place to start. These lessons demonstrate professional lighting techniques using only basic lighting tools. Having good lighting equipment is important, but knowing how to use it well is paramount! Lessons with Video At PhotoflexLightingSchool™, we realize that people learn in different ways.
