Helicoidal motion of a charged particle in a uniform magnetic field

A look at the pitfalls of arguing against science from incomprehension or emotion.

According to a paper in PLoS Computational Biology, "PageRank" can be applied to the study of food webs.

Researchers have devised a penny-sized silicon chip that uses photons to run Shor's algorithm - a well-known quantum approach - to solve a maths problem. The algorithm computes the two numbers that multiply together to form a given figure, and has until now required laboratory-sized optical computers. This kind of factoring is the basis for a wide variety of encryption schemes.

Arctic temperatures are now higher than at any time in the last 2,000 years, research reveals. Changes to the Earth's orbit drove centuries of cooling, but temperatures rose fast in the last 100 years as human greenhouse gas emissions rose. Scientists took evidence from ice cores, tree rings and lake sediments.

Carbon and nitrogen stable isotopes in fast food: Signatures of corn and confinement

From a Japanese TV show - a real life example of adding vectors and relative motion. The truck is moving at 100km/hr and a ball is shot backwards at 100 km/hr, resulting in it coming to a complete stop.

Earthship Biotecture creates buildings that... * Heat and cool themselves naturally via solar/thermal dynamics * Collect their own power from the sun and wind * Harvest their own water from rain and snow melt * Contain and treat their own sewage on site * Produce food in significant quantities * Utilize materials that are byproducts of modern society like cans, bottles and tires

A physical analysis of a player's movements, combined with a knowledge of the correct forces to apply at the right time, can be used to make a good player better. Scientific analysis like this is used in many sports, from figure skating to baseball

Is it easy to hit a home run in the major leagues?

A European spacecraft will begin its quest this week to make the most detailed global map of the Earth's gravity field.

The Stages of collapse of a star, neutron star formation and black hole formation.

Some very simple counter-weight trebuchet theory.

A very strange looking cloud.

Building a trebuchet from scratch and finding the best proportions, weights, angles etc by trial and error certainly works ..well, that's how the Grey Co's first machines were done... but if you could model the rock-throwing beasts mathematically then think of the work and possibly wasted effort you could save.

On the physics and mechanics of a medieval trebuchet, a type of catapult, its design, working and optimization through improved simulation and mathematical analysis.
