Einstein's Equivalence Principle Put to Test : Discovery News

Test of equivalence principle searches for effects of spin-gravity coupling

The Evolution of Time (Director's Cut) - So, if you liked science class in school; have a go at this one. a Total 3 and a half freak out session about mathematical theories and a version of the Universe that excludes the Big Bang. Huh? Yup !!

### 10241-1: Maersk Line Triple-E

LEGO 10241 - Maersk Line Triple-E / The name "Triple E" is derived from the class's three design principles: "Economy of scale, Energy efficient and Environmentally improved". These ships are expected to be not only the world's longest ships in service, but also the most efficient container ships per twenty-foot equivalent unit (TEU) of cargo. #PinYourResolution

Fractions with Starburst. 4.NF.1 Number & Operations- Fractions. Extend understandings of fraction equivalence and ordering. Explain why a fraction a/b is equivalent to a fraction by using visual fraction models with, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size.. Use this principle to recognize and generate equivalent fractions.

Perfect exposure settings: Reciprocity is the law of the relationship between shutter and aperture. It stipulates that one stop increases in aperture is equivalent to the shutter duration doubling. Both increase light by one stop.

1915, Albert Einstein published his papers on General Relativity and the Equivalence Principle which were received with a great deal of skepticism. According to General Relativity, the gravitational attraction between masses results not from some hidden force but from the warping of space and time by those masses. He also said there was no such thing as "ether". And, he predicted from his theory that light from distant stars would be bent by the sun.

### Triple star system 'can reveal secrets of gravity'

Triple star system can reveal secrets of gravity: A newly discovered triple star system that consists of a pulsar and two white dwarf stars who's orbits around the pulsar are smaller than the orbit of Earth around the Sun will help scientists study precise measurements of gravity and could resolve difficulties with Einstein's theories.
