Collective dynamics are ubiquitous in the natural world. From neural circuits to animal groups, there are countless instances in which the interactions among large numbers of elementary units bestow ...

Random thermal fluctuations in magnetic memory can be harnessed to reduce the energy required to store information, according to an experiment reported in the current issue of Physical Review Letters.

Research carried out at the University of Pennsylvania has definitively measured and described the Brownian motion of an isolated ellipsoidal particle, completing a path laid out by Einstein 100 years ...

A noninvasive data analysis technique has been developed that can discern whether an object's random motion is actively or thermally driven. Inside every living cell, internal structures are ...

A group of physicists in Italy believes that mobile bacteria could convert chemical energy into mechanical energy by pushing on the teeth of tiny gear wheels. The researchers used computer simulations ...

Normally, noise is something we scientists try to avoid. In the most advanced physics experiments, the goal is usually to measure something new. If you ever ask the experimenters why it took them so ...

A study in the US has revealed that, apart from motion due to tides, seismic activity and other geophysical phenomena, the ground also moves entirely at random, at least over scales ranging from ...

Today we continue on our journey of understanding motion, direction, and velocity. Continuing in our journey of understanding motion, direction, and velocity... today, Shini introduces the ideas of ...

IN 1905, Albert Einstein published five papers that shook the world of physics. His elegant arguments and conclusions were marvels of physical intuition that addressed dilemmas raised by experimental ...
