Understand why the electric force can be zero in electrostatics by exploring charge interactions, symmetry, and superposition. This video explains the physical intuition and mathematical reasoning ...
Purdue University physics professor Erica Carlson explains why static electricity is worse in winter and offers practical ...
Building on their pioneering 2018 research into how some of the body's cells, such as neurons and cardiac tissue, communicate ...
Finnish scientists sent electricity wirelessly using sound waves and lasers. "Acoustic wire" uses ultrasonic waves for contactless electricity transmission. Finland pioneers practical wireless ...
If you've ever watched a glass blower at work, you've seen a material behaving in a very special way. As it cools, the viscosity of molten glass increases steadily but gradually, allowing it to be ...
Researchers have developed a technique that allows them to carve complex three dimensional nanodevices directly from single crystals. To demonstrate its power, they sculpted microscopic helices from a ...
We describe electricity as a flow, but that’s not what happens in a typical wire. Physicists have begun to induce electrons to act like fluids, an effort that could illuminate new ways of thinking ...
Sodium-ion batteries (NIBs) are gaining traction as a next-generation technology to complement the widely used lithium-ion batteries (LIBs). NIBs offer clear advantages versus LIBs in terms of ...
One type of friction can waste energy even when two perfectly smooth surfaces move against each other, but researchers are getting a handle on how to attenuate or stop it completely ...
Electrostatics and Current Electricity is a reliable and high-scoring unit in the JEE Main examination. With well-defined concepts and repetitive question patterns, this section offers students a ...
As an electricity crunch drives bills higher around the country, big tech companies building power-hungry data centers are increasingly offering to pay for more of the energy they consume, so everyday ...
NASA gears up for a historic lunar flyby, AI gives stroke patients hope, and researchers discover the oldest known cave art What’s on the road to the launch of NASA’s Artemis II, how scientists are ...
