Scientists Make Model of the Entire Known Universe
One of the world's five most powerful supercomputers has modeled the structure of the known Universe, giving scientists fresh data on mysteries like the distribution of dark matter.
What's the Latest Development?
One of the world's five most powerful supercomputers has been used to construct the first-ever model of the entire observable Universe. Named CURIE, the computer is equipped with more than 92,000 CPUs and can perform 2 million billion operations per second. Scientists have used it, along with the standard model, to simulate the Universe with a cosmological constant from the big bang up to the present day. Two additional simulations will focus on "the cosmological evolution of models with dark energy, the mysterious component introduced to account for the accelerated expansion of the Universe."
What's the Big Idea?
The current simulation has already allowed scientists to discover new properties concerning the distribution of matter throughout the Universe. "The researchers have found that the first galaxy clusters formed when the Universe was only 2 billion years old and the most massive cluster in the observable Universe today weighs 15 quadrillion (or 15 thousand trillion) solar masses." The simulation has also revealed, with unprecedented accuracy, the imprint of the Baryon Acoustic Oscillations which are responsible for the distribution of dark matter. The data are being called a "gold mine" for the cosmological community.

Blackstone's Byron Wien, Vice Chairman of Private Wealth Solutions Group, gave a speech laying out the wisdom he learned during his 80 years. Here are 15 of Wien's best life lessons, which teach us about improving our productivity, sleep, burnout avoidance, and everything in between.
According to TwoFold CEO Alison McMahon, a leader who doesn't care (or can't pretend to care) about his or her employees isn't much of a leader at all.
Why do people quit their jobs? Surely, there are a ton of factors: money, hours, location, lack of interest, etc. For Alison McMahon, an HR specialist and the CEO of TwoFold, the biggest reason employees jump ship is that they're tired of working for lousy bosses.
By and large, she says, people are willing to put up with certain negatives as long as they enjoy who they're working for. When that's just not the case, there's no reason to stick around:
Nine times out of ten, when an employee says they're leaving for more money, it's simply not true. It's just too uncomfortable to tell the truth.
Whether that's true is certainly debatable, though it's not a stretch to say that an inconsiderate and/or incompetent boss isn't much of a leader. If you run an organization or company, your values and actions need to guide and inspire your team. When you fail to do that, you set the table for poor productivity and turnover.
McMahon offers a few suggestions for those who want to hone their leadership abilities, though it seems that these things are more innate qualities than acquired skills. For example, actually caring about your workers or not depending wholly on HR thinking they can do your job for you.
It's the nature of promotions that, inevitably, a good employee without leadership skills will get thrust into a supervisory position. McMahon says this is a chronic problem that many organizations need to avoid, or at least make the time to properly evaluate and assist with the transition.
But since they often don't, they end up with uninspired workers. And uninspired workers who don't have a reason to stay won't stick around for long.
