A simple nonlinear regression technique is presented for obtaining the equation of settling velocity as a function of sludge concentration based on the data obtained from multiple batch settling tests ...

Scientists are testing a novel way to measure cosmic expansion using time delays in gravitationally lensed quasars. Their results match “local” measurements but clash with early-universe estimates, ...

New measurements of a subatomic particle provide the strongest hint yet that the leading theory of quantum physics that explains our universe may be missing a fundamental element, scientists say. The ...

Time, not space plus time, might be the single fundamental property in which all physical phenomena occur, according to a new theory by a University of Alaska Fairbanks scientist. The theory also ...

Linear measurement tools are essential for determining the dimensions of an object. These tools provide a way to quantify distance in a straight line. In engineering and physics, getting your ...
