In the quantum world, processes can be separated into two distinct classes. One class, that of the so-called "perturbative" phenomena, is relatively easy to detect, both in an experiment and in a mathematical computation. Examples are plentiful: the light that atoms emit, the energy that solar cells produce, the states of qubits in a quantum computer.
When dogs were first bred to live with humans, their caretakers were always around. They lived on farms and villages or were traveling companions for nomads.
We spoke with Dr. Kerry O’Grady about how you can make reviews really count. Whether you dread it or see it as a golden opportunity, the employee review is as ubiquitous to the traditional workplace experience as a free pretzel day or casual Friday. But if leaders conduct reviews the right way, they’re not going […]
Commencement ceremonies for Northeastern University were held Sunday at Boston's Fenway Park, where some graduates tried to disrupt the event.
Social media is one of the most talked about topics in recent years, as it has grown to the point of impacting every single aspect of our lives. Long gone are the days of social media working as just a place to chat and share pictures of your kids or cats – nowadays, we use […]
Pro-Palestinian protesters briefly disrupted a graduation ceremony at the University of Michigan today as universities holding commencements braced for more tensions generated over the war in the Gaza Strip.
The best noise-cancelling earbuds to get right now, tested by us.
Whether it’s blocking the noises of your daily train ride, trying to be productive at a coffee shop or just needing to tune out the world for a while, noise-canceling earbuds can provide solace. But, as is the case with all audio gear, the effectiveness of active noise cancellation (ANC) can vary greatly from model to model, even with products from the same company. We test dozens of sets of wireless earbuds every year, and I’ve shortlisted a selection of the absolute best in terms of pure ANC...
Gravity is part of our everyday life. Still, the gravitational force remains mysterious: to this day we do not understand whether its ultimate nature is geometrical, as Einstein envisaged, or governed by the laws of quantum mechanics.
When I was growing up in the ’80s in Santiago, Chile, during the Pinochet dictatorship, air quality was the environmental problem most present in our lives. It determined whether we could drive that day, how overwhelmed hospitals would be, and whether or not we would have physical education at school. Global warming was unheard of. And plastic was our friend: a cheap, versatile, and durable material that let us play, move about, and simplify our lives. We never anticipated its long-lastingness...
Quantum mechanics is simultaneously our most powerful and weirdest scientific theory. It’s powerful because it offers exquisite control over the nanoworld of molecular, atomic, and subatomic phenomena. It’s weird because, while we have a complete mathematical formalism, we physicists have been arguing for more than a century over what that formalism means. In other words, unlike other physical theories, the mathematics of quantum mechanics has no clear interpretation. That means physicists and...
The combat sports world is rolling in the dough. Money magazine Forbes recently took a look at the most valuable properties in the industry and released a list of organizations enjoying the fruits of their labor. With an $11.3 billion valuation, the UFC stood on top of the rankings. The American promotion has had another incredible year thanks to its partnership with ESPN, and having just come off a merger with professional wrestling juggernaut WWE. The WWE sat in the […] The post Forbes Ranks...
