    What is Exascale Computing?

    We’ve covered what super computers are here in this video, and they are indeed super. The fastest machines today are in the realm of petascale computing, that’s more than a quadrillion computing operations per second. The most powerful computer in the world today is Summit, the supercomputer at Oak Ridge National Lab. It’s followed closely by Lawrence Livermore’s Sierra supercomputer, but even today’s most powerful high-performance machines can’t keep up with the demands of the increasingly complex simulations required for national security, precision medicine, climate research, and a host of other areas of basic science. So, what’s next ? Some computing experts have called improving computing performance on this huge…

    Exascale Computing is Here: El Capitan

    *Music* Quinn: El Capitan is the result of a second collaboration of the CORAL partners, which are Oak Ridge, Argonne, and LawrenceLivermore National Laboratories. The first collaboration resulted in Sierra, which is sited at our Lab. The program, the NNSA program looked out beyond 2023 at our nuclear weapons needs and came up with a number of requirements that we wanted to achieve with the El Capitan system. And one of the key ones is that it perform an order of magnitude better on some important calculations over Sierra in that timeframe to meet those objectives. Clouse: I think exascale computing is kind of the next step in improving our…

    Will We Ever Be Able to Travel Through a Wormhole?

    What happens when you have two black holes, quantum particles and a hell of a lot of gravity all in one place!? Traversable wormholes!! AKA a time machine? Many of you guys might’ve seen this demo of how a wormhole works. So if you have two points on a piece of paper… Like two planets in space that you want to travel between really quickly. If you fold space in half, you can get the two points (or planets) to connect. This is the idea of how a wormhole works… and possibly time travel. But for that to exist, we’d need huge warping of spacetime, which is really hard for…

    Will We Ever Time Travel? Scientists Say ‘No’ Based on This New Discovery

    So, this is probably what you think of when you picture an atom, right? The thing is, the central part of this model is just plain inaccurate. Scientists recently found the nucleus of some atoms don’t look like this at all, and it’s causing a ruckus because well, this newfound shape straight up shouldn’t exist. When you learned about atoms in school, you probably learned about a couple of different models– and one thing was likely always the same- the nucleus was spherical. But it turns out that might’ve been too simple. Atomic nuclei are made up of protons and neutrons that are held together by the Strong Nuclear Force…
