Abstract: Elastic constants of metal can be extracted by measuring the ultrasound longitudinal and shear wave velocities. The Electromagnetic Acoustic Transducer (EMAT) technique provides a ...

Abstract: This paper reports on the langatate (LGT) elastic constants and their temperature coefficients measured from room temperature (25degC) to 1100degC using resonant ultrasound spectroscopy (RUS ...

Scientists from Brazil are challenging the traditional view of universal constants, proposing that only one constant—time itself—is needed to measure relativistic spacetime. The research team argued ...

Often, we observe that two pieces of data, which are not supposed to have any relationship, appear to have a very high correlation. What makes the apparent good correlation is that they both exhibit ...

The article by Jacklin Kwan on the number of fundamental constants there are (or should be) raises an important issue that cuts to the heart of physical theory: are constants genuine features of ...

It appears that we live on the knife-edge, where only the narrowest combination of values for the fundamental constants allow life, and especially conscious life, to arise. When you purchase through ...

There are (probably) less than two dozen fundemental constants that define the physics of our universe. Determining the value of them might seem like the sort of thing for large, well funded ...
