I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
Watch a small metal ball drop through a tube, and normally that’s it; blink, and it’s over. But drop it through MetMo Eddy, and something strange happens: the fall stretches out, like gravity took a breath. This palm-sized copper cylinder is a precision-machined desk toy that turns a real electromagnetic effect into something you can…
“This lightweight exoskeleton doesn’t need batteries to give you superhuman powers” We’ve seen our fair share of real-world exoskeletons that try to show how manual labor could be different in the future, even without the help of robots. True to the common image of these mechanical suits, these exoskeletons are often large, heavy armors that…
“#The multiverse theory, explained – Macleans.ca” The term you’re hearing more frequently combines comic-book cinema with quantum mechanics A random number is printed on the copyright page of theoretical physicist Sean Carroll’s 2019 book Something Deeply Hidden. In our universe, each copy of the book shows that same number: 756,132,390,815,553. But that’s just one of…
“#Here’s what happens when a beam of subatomic particles hits you in the face” What would happen if you stuck your body inside a particle accelerator? The scenario seems like the start of a bad Marvel comic, but it happens to shed light on our intuitions about radiation, the vulnerability of the human body, and…
“#How the physics concept of ‘negentropy’ can change your life” Life is full of small decisions: Should I pick up that sock on the floor? Should I do the dishes before bed? What about fixing the leaky faucet in the bathroom? Leaving a sock on the ground is a manifestation of a concept from physics…
“#If God broke the laws of physics, would scientists even notice?” I still believed in God (I am now an atheist) when I heard the following question at a seminar, first posed by Einstein, and was stunned by its elegance and depth: ‘If there is a God who created the entire universe and ALL of…
“#Quantum physics has the answer to making better holograms” Once, holograms were just a scientific curiosity. But thanks to the rapid development of lasers, they have gradually moved center stage, appearing on the security imagery for credit cards and banknotes, in science fiction movies – most memorably Star Wars – and even “live” on stage…
“#Achievement isn’t why more men are majoring in physics, engineering and computer science” Credit: Pixabay/CC0 Public Domain While some STEM majors have a one-to-one male-to-female ratio, physics, engineering and computer science (PECS) majors consistently have some of the largest gender imbalances among U.S. college majors—with about four men to every woman in the major. In…
