AN absolute determination of the acceleration due to gravity at a site in the National Physical Laboratory has recently been completed. It is the first to be made by timing the symmetrical up-and-down ...

According to legend, Galileo dropped weights off of the Leaning Tower of Pisa, showing that gravity causes objects of different masses to fall with the same acceleration. In recent years, researchers ...

Although we take a lot of scientific knowledge for granted today, each of the basics – whether it be about light, gravity, mass or the shape of the Earth – had to be theorized and experimentally ...

When they look for violations of Einstein’s general relativity, physicists deliberately plan experiments to find nothing at all. In 1887, physicists Albert Michelson and Edward Morley performed one of ...

Engineers from Caltech have discovered that Leonardo da Vinci’s understanding of gravity—though not wholly accurate—was centuries ahead of his time. In an article published in the journal Leonardo, ...

Leonardo da Vinci becomes more of a scientist with age and performs experiments to test theories. Muslim scientists in the Middle East had been testing their theories with experiments for a long time.

You see this all the time in textbooks: This is often described as "the acceleration due to gravity". Is this really the best thing to call this? No. A better name would be "the local gravitational ...

In physics there are two broad ways to look at the world. One is the classical realm of Newton and Einstein, where objects have definite form and interact in clearly determinate ways. The other is the ...

On Wednesday (Sept. 27) morning, an international team of physicists reported a major finding about an elusive form of matter known as antimatter. It appears that antimatter responds to gravity the ...
