Towering structures must be able to bend and sway when subjected to the forces of wind and ground movement, or they will ...

Something that probably unites many Hackaday readers is an idle pursuit of browsing AliExpress for new pieces of tech. Perhaps it’s something akin to social media doomscrolling without the induced ...

Low-frequency resonance is a bigger problem than high-frequency resonance in general industrial machines. This little-recognized distinction is crucial in determining the best way to correct it.

A quartz crystal's case will be stamped with the devices' rated operating frequency, but that number is only an approximation to the real story which is that there is more than one crystal resonant ...

This facility is a shared resource serving the University of Wyoming community and beyond. It currently houses six NMR spectrometers that are used for a multitude of research in science, engineering, ...

Harmonic distortion is not a problem unless it becomes a problem. Harmonics are a breakdown of a distorted waveform into its separate frequencies, which are integer multiples of the fundamental ...

Almost anytime physicists announce that they’ve discovered a new particle, whether it’s the Higgs boson or the recently bagged double-charm tetraquark, what they’ve actually spotted is a small bump ...

Sound is one of the great mysteries. It surrounds us all the time, yet it is invisible and has no smell. Except for the most booming of subwoofers, we rarely feel its vibrations on our skin. In fact, ...

A team of scientists has discovered an electrical detection method for terahertz electromagnetic waves, which are extremely difficult to detect. The discovery could help miniaturize the detection ...
