April Flowers for redOrbit.com - Your Universe Online Humans have thrown a lot of junk into space since the Space Race began in the late 1950s. NASA has an entire website devoted to the types and sizes of space trash orbiting the planet — from defunct spacecraft and launch vehicle stages all the way down to specks of paint released by thermal stress or small particle impacts. NASA estimates that over 21,000 bits of orbital debris larger than 10 centimeters exists currently. The numbers...

Lee Rannals for redOrbit.com - Your Universe Online The U.S. Naval Research Laboratory Spacecraft Engineering Department's space robotics research facility has gotten its hands on a tool to help emulate inertia in space. The 75,000 pound Gravity Offset Table (GOT) is made from a single slab of solid granite, and will help emulate the mechanics of physics found in space. The frictionless large surface area will allow researchers to replicate the effects of inertia on man-made objects...

It's an occurrence that happens so fast it cannot be followed by the human eye.  However, researchers at MIT, Virginia Tech and Princeton University announced on Thursday that they have solved the mystery of how cats lap liquids with such elegance. Using high-speed cameras, the researchers found that domestic cats and larger felines like tigers use their tongues to delicately draw up water without breaking the surface of the liquid, harnessing a perfect balance between the physical...

Scientists are now discovering why a jockey's posture during a horse race speeds up the horse. The Royal Veterinary College team reported Friday in the journal Science that after 100 years of recorded race times, the biggest improvement in speed came around the turn of the 20th century when jockeys changed their posture.  The change was a 5 to 7 percent difference in the U.S. and Britain. The researchers stuck a GPS unit in some jockeys' helmets and inertia sensors on the riders and...

GARDINER, N.Y., June 23 /PRNewswire/ -- "The Universal Properties of Acceleration: Did Einstein Look the Wrong Way?" (published by AuthorHouse) is about gravity. Author Barry Lebost proposes a new law in physics stating "that all acceleration and its intimate partner inertia have the same general properties everywhere in the universe including the surfaces of planets and stars." Lebost demonstrates that when universal property tests are performed upon the surface of planet Earth, the test...

The U.S. space agency and Honeywell Inc. say they are launching the 2009 tour of their award-winning hip-hop science education program FMA Live! The traveling science concert will reach more than 17,000 middle-school students during its 10-week, 20 city U.S. tour, the National Aeronautics and Space Administration said. Named for Sir Isaac Newton's second law of motion -- force = mass times acceleration -- FMA Live! uses professional actors, original songs, music videos and interactive science...

Base running and base stealing would appear to be arts driven solely by a runner's speed, but there's more than mere gristle, bone and lung power to this facet of baseball "” lots of mathematics and physics are at play. With baseball playoffs heating up and the World Series right around the corner, it's guaranteed that fans will see daring slides, both feet-first and head-first, and even slides on bang-bang plays at first. Who gets there faster, the head-first slider or the...

The Incredible Hulk makes a terrific leap, and physicist Alejandro Garcia cringes. It's not because Bruce Banner's alter ego is angry and green, but because the ground underneath stood still. Newton's laws say that the force of the jump should have destroyed the launch site. "You can tell when something isn't quite there," Garcia said. "Often the audience doesn't like it, and they can't quite put their finger on it." So the San Jose State University professor is trying to bring the rules of...

At the core of ESA's LISA Pathfinder mission sit two small hearts. Each is a cube, just 5 centimetres across. Together they will allow LISA Pathfinder to lay the foundations for future space-based measurements that investigate the very core of Einstein's General Relativity. A cornerstone of relativity is the concept of a frame of reference. This is a set of bodies relative to which any motion can be measured. Without a reference frame, no motion through space can be detected. Scientists...

The Seismometer is an instrument designed to measure the motions of the ground. This includes seismic waves generated by earthquakes, nuclear explosions, and other seismic sources. Records of these activities allow seismologists to map the interior of the Earth, and locate and measure the size of the different sources. There are also seismographs, which is sometimes used in place of the word seismometer. However, a seismograph is the older instrument in which the measuring and recording...

General Relativity -- General Relativity is the common name for the theory of gravitation published by Albert Einstein in 1915. According to general relativity the force of gravity is a manifestation of the local geometry of spacetime. Although the modern theory is due to Einstein, its origins go back to the axioms of Euclidean geometry and the many attempts over the centuries to prove Euclid's fifth postulate, that parallel lines remain always equidistant, culminating with the...
