In a reality flooded by Harry Potter and science fiction movies, levitation has turned into a fact. The same physicists that showed last year that invisibility cloaks are feasible, now have turned to levitation. The team at the University of St Andrews, Scotland, has made an 'incredible levitation effects' ... |

Although they did not find out how Moses could separate the water of the Red Sea, they were able to do the same with a mass of sand grains, in an experiment which proves that no outside force is necessary to make identical molecules part.Scientists at the Rutgers University, New Jersey, proved that two identical pop... |

Fictitious forces, or pseudo forces are, as their name suggests, apparent forces that exert their influence on every object that has a mass in a rotating reference system. The fact that we are living in such a system, the Earth, means that we are influenced by these forces every day.The first weird thing about these... |

The name comes from the fact that Brazil nuts, in a container of mixed nuts, always come on top when the container is shaken, even though they are the largest and heaviest in the bunch.

The impact force has the greatest effect when it's applied over a short time period and it is equal to the mass of the hitting object times the acceleration. This means that a stone weighing one kilogram (2.2 pounds) moving at 50 m/s (1600 ft/s) will have the same impact force as a 10 grams rock moving at 500 ... |

A gravitomagnetic field is an approximation to the Einstein field equations for general relativity, valid under certain conditions, a reformulation of gravity described as a so far fictitious force around a moving, gravitating body.Much like a moving electric charge that creates a magnetic field, a gravitomagnetic f... |

Common sense tells us that the Earth's gravitational force should be equal all around the world. Well, it's not! The inhabitants of northern Canada may not be numerous, but they are the slimmest people on the planet.A new study shows that that specific region of the country feels less gravitational pull th... |
