This video presents the analytical solution for the electric field along the axis of a uniformly charged disk. Starting from Coulomb’s law, we derive the exact expression and discuss its physical ...

In this video, we derive the electric field between two charged plates using fundamental principles of electrostatics. Step-by-step reasoning, clear equations, and physical intuition are used to show ...

For as long as people have watched storms roll across the sky, lightning has inspired awe and fear. You can see the flash and ...

Red arrows indicate the nuclear spin axes at the positions of the N3 nitrogen atoms on the guanine (G) bases. Due to the helical structure of DNA, there is an angular deviation in the orientation of ...

As the Parker Solar Probe ventures closer to the sun, we are learning new things about our home star. In a new study, physicists led by the University of Iowa report the first definitive measurements ...

NASA scientists have discovered a planet-wide electric field surrounding Earth, confirming a 60-year-old hypothesis. Studying the field could yield some vital information about how our planet's ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...
