CAMBRIDGE, MA— Prof. Subir Sachdev, the Herchel Smith Professor of Physics and Chair of the Department of Physics at Harvard University and one of the top physicists in the area of quantum physics in the world, called on Indian scientists and academicians to speak up against any effort to stifle truth and science even if it puts funding of their institutions in potential jeopardy.
Imagine conseguir uma vaga na NASA, a concorrida agência espacial americana. Agora imagine que, uma vez lá dentro, tudo fica muito mais difícil, porque seu trabalho é enviar coisas que custam entre milhões e bilhões de dólares para o espaço.
Dark matter might well be the biggest mystery in the Universe. We know there’s something out there making things move faster than they should. But we don’t know what it is, and we sure as heck don’t know where it came from.
One of the ultimate goals of modern physics is to unlock the power of superconductivity, where electricity flows with zero resistance at room temperature.
Progress has been slow, but in 2018, physicists have made an unexpected breakthrough. They discovered a superconductor that works in a way no one’s ever seen before – and it opens the door to a whole world of possibilities not considered until now.
In other words, they identified a brand new type of superconductivity.
No new particles have been found at the Large Hadron Collider since the Higgs boson in 2012, but physicists say there’s much we can still learn from the Higgs itself.
Reductionism breaks the world into elementary building blocks. Emergence finds the simple laws that arise out of complexity. These two complementary ways of viewing the universe come together in modern theories of quantum gravity.
IN THE 1960S, the charismatic physicist Geoffrey Chew espoused a radical vision of the universe, and with it, a new way of doing physics. Theorists of the era were struggling to find order in an unruly zoo of newfound particles. They wanted to know which ones were the fundamental building blocks of nature and which were composites. But Chew, a professor at the University of California, Berkeley, argued against such a distinction. “Nature is as it is because this is the only possible nature consistent with itself,” he wrote at the time. He believed he could deduce nature’s laws solely from the demand that they be self-consistent.
