Elon Musk's dad says he's not proud of Tesla founder and explains kids with stepdaughter

Image
Elon Musk’s dad has admitted he isn’t proud of his billionaire son and explained why he married and had a baby with his stepdaughter in a candid radio interview. Errol Musk, 76, was called to Kyle and Jackie O’s show Monday morning for a bizarre 20-minute interview in which he joked that he could be Kyle’s real father. The Tesla CEO’s father said Elon had ‘overstepped the mark’ of what he considered successful but said the Musk family had ‘done a lot for a long time’. ‘Your descendant is a genius. He’s worth so much money and has created so many things, you can’t take that away from him. Are you proud?’ Jackie O asked. ‘Not. You know, we’re a family that’s been doing a lot for a long time, it’s not as if we suddenly started doing something,’ Errol replied.

Sneaky black hole discovery explains star death, black hole formation, and gravitational waves

Calçada, CC BY There is always something new and exciting going on in the field of black hole research. Albert Einstein first published his book explaining the general theory of relativity—which postulates black holes—in 1922. One hundred years later, astronomers captured the true image of the black hole at the center of the Milky Way. In a recent paper, a team of astronomers describes another exciting new discovery: the first “dormant” black hole observed outside a galaxy. I am an astrophysicist who has studied black holes—the densest objects in the universe—for nearly two decades. An inactive black hole is a black hole that does not emit detectable light. Because of this, they are notoriously hard to find. This new discovery is exciting because it provides insight into the formation and evolution of

Hardwick explains Richmond's late sub-call when question is asked over high defender injury

Richmond coach Damien Hardwick has explained why tall defender Ben Miller was substituted in the final quarter of the Tigers’ crucial draw with Fremantle. Key points: Tigers defender Ben Miller was medically substituted at the end of the game with Fremantle Reports differ as to why Miller was left out of the game, with Damien Hardwick saying it was a calf injury A player may only be substituted if he is reasonably determined as medically unfit to participate in any match for at least the next 12 days With Richmond leading by one goal after 16 minutes of play in the final quarter, Miller came on to the bench and was medically out of the game for the smaller, faster Maurice Rioli. A minute later, Fremantle equalized through Bailey Banfield’s goal, which led to the first draw of the 2022 AFL season. The substitution raised eyebrows, with Miller not appearing to suffer any visible injury. A medical substitute rule is in place ahead of the 2021 season, with doctors supposed to determine “a

Polarization of light creates art, explains mathematical concepts

Stochastic stress-induced birefringence in plastic spoons left in the hot sun was visualized via polarization-filtered staining. The ladle is placed between a pair of parallel polarizer sheets in an open-gate arrangement, with a parchment paper backing to act as a diffuser for sunlight illumination. Credit: Aaron Slepkov, University of Trent Light polarization supports the latest technological innovations, including 3D cinema and LCD. In LCDs, small, electronically controllable liquid crystal elements are sandwiched between the polarizers. If, on the other hand, other transparent polarization-altering films—such as plastic gift wrap and wrapping tape—are placed between a set of polarizers, a polarizing filtered color array can be observed. In American Journal of Physics Aaron Slepkov, of Trent University in Canada, explores the physics of how these colors appear, how they can be controlled, and why subtle changes in viewing angles, s
