The Earth rotates at about 1,670 kilometers per hour at the equator, yet we experience no sense of motion. But how is this possible? To understand why we don’t feel Earth's rotation, it’s essential to ...

This paper describes a mathematical model for head injury prediction based on the hypothesis that injury results from a combination of displacement and rotation of the brain inside the skull. The ...

The interior of the Sun does not rotate at the same rate at all latitudes. The physical origin of this differential rotation is not fully understood. It turns out, long-period solar oscillations ...

Shapes can be transformed in a number of ways. These include translation, rotation and reflection. Translation causes a shape to move. Rotation causes a shape to move. Reflection causes a shape to ...

These motions were measured by analyzing 10 years of observations from NASA's Solar Dynamics Observatory (SDO). Using computer models, the scientists have shown that the newly discovered oscillations ...

Although we’re living in the twenty-first century, there are still many dangers in our workplaces. For certain industries, such as the construction, manufacturing and industrial industries, the risks ...

It’s hard to put your finger on exactly what makes a running stride “good,” as we’ve learned from an endless succession of inconclusive and often contradictory biomechanics studies over the years.

The Sun’s differential rotation pattern has puzzled scientists for decades: while the poles rotate with a period of approximately 34 days, mid-latitudes rotate faster and the equatorial region ...
