Rotating bodies often move in surprising ways with flips and wobbles that reveal the hidden rules of physics. Car sitting at ...

Mathematicians thought that they understood how rotation works, but now a new proof has revealed a surprising twist that ...

For the first time, physicists have simulated what objects moving near the speed of light would look like — an optical illusion called the Terrell-Penrose effect.

A rack and pinion steering system consists of a pinion (a circular gear) with a rack (a linear gear). The system works by converting a revolving motion into linear motion. Most cars, small trucks, and ...

The trend toward diversifying from U.S. stocks to overseas equities is set to accelerate over the next six to 12 months. That’s the call of MRB Partners, an independent strategy firm, who believe the ...

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 ...

Physics, particularly forces and motion, can be challenging. By observing everyday motion, conducting simple experiments, and understanding Newton's laws in plain language, the concepts become more ...

Need for measurement: Units of measurement; systems of units; SI units, fundamental and derived units. significant figures, Determining the uncertainty in result. Dimensions of physical quantities, ...

Mathematicians have finally succeeded in unifying the laws of physics that govern the motions of particles at different scales. Their efforts resolve a question set by mathematician David Hilbert in ...

The construction industry must find a balance between safety and individual autonomy: Proper education about the risks of rotational motion, TBIs, and more. Safety systems with the aim of reducing the ...
