Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I ...

Deluged by responses to his request for your favourite units, Robert P Crease discovers that non-SI units persist, and are sometimes even popular, among the physics community Setting the standard ...

This week, Sam Kean takes a look at some ridiculously precise standards -- the meter, the second, and other international standard units -- and the role that elements have played in defining ...

A UNIT of pressure in terms of the height of the column of a liquid manometer is essential, since such an instrument, including the compression manometer (McLeod gauge), is indispensable in the ...

At the core of a quantum computer is the quantum processor, but these technologies are vastly different from the CPUs found ...

Save guides, add subjects and pick up where you left off with your BBC account. A unit of measurement is one unit of a quantity: for example, one second. Standard units of measurement are the ...

The standard is not an intrinsic or natural foothold that is a gift from nature, but the outcome of recipes involving technologies of human invention. I have mentioned a few non-SI units that arose ...

The Standard Model of Particle Physics is the collection of discoveries and theories that describe the smallest units of matter and the interactions between energy and matter. According to this model, ...

That property is predicted by the standard model of particle physics, the theory that describes particles and forces on a subatomic level. In fact, it’s the most precise prediction made by that ...

The Department of Physics and Astronomy at the University of Delaware is a vibrant hub of scientific inquiry, ... Results of this research were applied, for example, to develop the 2019 SI standard of ...
