Transistors are fundamental to microchips and modern electronics. Invented by Bardeen and Brattain in 1947, their development ...

It's time for another physics example. In this case, I am going to calculate the electric field due to an electric charged rod. Of course you could do this analytically using a bit of calculus.

OK, but let's get back to this relationship between the electric field and the electric potential. For this example of a constant electric field, I can solve for the magnitude of the electric ...

and living human cells will move along an electric field, for example in wound healing. Now researchers have found the first actual 'sensor mechanism' that allows a living cell detect an electric ...

People used to think that perceiving natural electric fields was something that animals only did in water. Sharks and eels can do it, for example. The platypus and spiny anteaters were the only ...

“The sensitivity to weak electric fields helps a dolphin search for fish ... from time to time by changing ocean currents, for example, with an influence on the Earth's magnetic field, or ...

The researchers found that, rather than crawling up the walls of the dish, the worms were leaping from the bottom of the plate to the lid—and they were using electric fields to do so.

Scientists found that dolphins have an ability to sense electric fields, which may help them hunt and navigate the seas. By Carolyn Wilke Newborn bottlenose dolphins sport a row of hairs along the ...
