Exactly 200 years ago, a French engineer introduced an idea that would quantify the universe’s inexorable slide into decay.

We study Hooke’s law for elastic matter, Newton’s law of friction in fluids, as well as simple viscoelastic models (stress-strain relations). We consider the derivation of fundamental equations of ...

Instead of derivation of Kalman filter, I introduce Kalman filter from weighted average and moving average. I expect that readers will have intuition on Kalman filter such as meaning of equations.

Nuclear theorists at Brookhaven National Laboratory and Argonne National Laboratory have successfully employed a new ...

Ferrocene is a key molecule for developing molecular machines. However, it readily decomposes on the surface of flat noble metal substrates, marking a significant challenge. Now researchers have ...

In Solvej Balle’s new series of novels, the concept of a time loop is more than a gimmick; it’s a way of rethinking human ...

Mantle motions have major effects on topography and the distribution of ice sheets. The motions are key for researchers ...

The Princess of Wales has been married to Prince William since April 2011 and together they share three children: Prince George, Princess Charlotte, and Prince Louis. The family reside at Adelaide ...

In a regular electric motor, current flowing through coils generates a magnetic field that interacts with other magnetic fields, causing motion. In contrast, an electrostatic motor relies on the ...
