Abstract: In physical human-robot interaction, active compliance is often preferred above passive compliance, since it makes the control of the output impedance easier than with the use of passive ...

In physics, we have a bunch of constants that are used in models to explain how the world works. These are fixed numbers that we plug into equations along with our variables. For example, the ...

It's fun to think about the fundamental physical constants. These are special values used in our models of the physical universe. They include things like the speed of light, the gravitational ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Planck's constant reveals the quantum world's fundamental energy levels. It shows how light and matter exist in discrete units (quanta). This constant defines limits to our knowledge of particle ...

A torque wrench (pronounced "tork") is one of the essential tools you need before starting an engine rebuild, and helps determine when the appropriate amount of force has been applied to a fastener ...

The first day of spring is Thursday. The spring equinox will occur at 5:01 a.m. EDT on Thursday. An equinox occurs when the Earth's equator aligns with the sun, resulting in a "nearly" equal amount of ...

Mathematicians attended Roger Apéry’s lecture at a French National Center for Scientific Research conference in June 1978 with a great deal of skepticism. The presentation was entitled “On the ...

Phoenix Springs, the debut game from Calligram Studio, is immediately striking no matter your familiarity with point and click adventure games. The developer creates self-proclaimed "arty text games", ...

A buzzword floating around the equipment industry needs to be unpacked: “zero-torque” or “torque-free.” There’s a good chance you’ve heard about one or both — even if they mean the same thing. In an ...
