Installation demonstrates how terawatt lasers can control and safely divert lightning
Almost 270 years since Benjamin Franklin invented the lightning rod, lightning protection is still based on this same concept. Although we can't deny the benefits of lightning rods, major drawbacks do remain. Installing permanent lightning rods isn't often feasible, and lightning rods also only protect against the direct effects of lightning. By attracting lightning strikes to conduct their current to the ground, lightning rods may even cause additional and more severe indirect effects, such as electromagnetic interference and voltage surges in devices and appliances.

This Physicist Discovered an Escape From Hawking’s Black Hole Paradox

In 1974, Stephen Hawking calculated that black holes’ secrets die with them. Random quantum jitter on the spherical outer boundary, or “event horizon,” of a black hole will cause the hole to radiate particles and slowly shrink to nothing. Any record of the star whose violent contraction formed the black hole — and whatever else got swallowed up after — then seemed to be permanently lost.

How Steven Weinberg Transformed Physics and Physicists


Steven Weinberg, who died on July 23, towered over theoretical physics in the second half of the 20th century. He strongly believed that, armed only with the fundamental principles of relativity and quantum mechanics, the theoretical physicist can examine all phenomena in the universe — from the smallest to the largest scales. His work transformed our understanding of every aspect of fundamental physics in startlingly deep and original ways.

Locations of Riemann zeros accurately measured
The Riemann hypothesis raised in 1859 is one of the six unsolved Millennium problems, and its proof greatly facilitate the understanding of the distribution laws of prime numbers. For a long time, there has been a growing academic focus on the non-trivial zeros of the Riemann zeta function. This enables physicists to reproduce prime numbers and inspires them to discover the essence of Riemann hypothesis with a feasible quantum approach.
