According to Theodor Hänsch, director at the Max Planck Institute for Quantum Optics (MPQ) in Germany and one of the winners of the 2005 Nobel Prize in Physics, a laser frequency comb can now be used ...
Wide binary stars with separation greater than about 2000 astronomical units are interesting natural laboratories that allow a direct probe of gravity at low acceleration weaker than about 1 nanometer ...
Helmholtz Zentrum Dresden-Rossendorf (HZDR), which conducts long-term research in the fields of energy, health and matter, has announced the development of a new diagnostic tool specified for a ...
Researchers from SANKEN (The Institute of Scientific and Industrial Research), at Osaka University find a simple and elegant way to measure pressure and acceleration using the same device Osaka, Japan ...
Imagine you want to study what happens when an object accelerates. Oh, this is way before any of that internet stuff—also, no computers or electronics. In fact, let's say it's the year 1780. What do ...
The question of how fast the universe is expanding just keeps getting more confusing. Our two main methods of measuring the acceleration of the universe’s expansion disagree by nine per cent.
