Stephen Hawking Thinks Our History Is That "Of Stupidity"
1 of 35
Studying the past is really only helpful if you can use it to benefit the future. If you can't learn from the mistakes of yesterday, the same mistakes get repeated. Even so, there's more to life than studying where humanity went wrong. Stephen Hawking made this point when he said, "We spend a great deal of time studying history, which, let's face it, is mostly the history of stupidity. So it's a welcome change that people are studying instead the future of intelligence." Hawking made this comment in an October 2016 lecture at the opening of the Leverhulme Centre for the Future of Intelligence (LCFI) at Cambridge University. The center is a multi-disciplinary institute that will look to address the unanswered questions around artificial intelligence.
BRIXO Blocks Take Fun With Legos To A Smart New Level

Playing with toy blocks seems childish, right? Not so fast. BRIXO blocks are like Legos on steroids, and they've got a lot to teach kids and adults alike. These blocks are coated in chrome and conduct electricity, which means they can add light, motion, or sound to any building block creation. They're perfectly compatible with Legos, so adding just a few BRIXO blocks to your Lego castle can give it new life. And since they are basically robotic instruments, BRIXO blocks make it socially acceptable for adults to play with blocks.
The Cybathlon Is The Olympics For Bionic Athletes

If you love the Olympic games and robotics, then, boy, do we have a treat for you. Meet the Cybathlon. This competition is the Olympics for bionic athletes. A coalition of Swiss robotics labs helped the first-ever Cybathlon take place in their home country in October 2016. The competition, which is modeled after the Olympics, sees athletes with robotics assistance competing in a variety of events. The National Centre of Competence in Research (NCCR) Robotics hosted the competition in an attempt to drum up interest in human-oriented robotics technologies. The Cybathlon has six events: a bike race, leg race, wheelchair race, exoskeleton race, arm prosthetics race, and Brain Computer Interface race for competitors with full paralysis. See the athletes in action in the video below.
A Matrioshka Brain Is A Computer The Size Of A Solar System

Imagine a computer the size of a solar system. For power, it would use a Dyson sphere—a solar array that completely surrounds the host star to collect almost all of its energy. That energy-collecting sphere would double as an ultra-powerful computer processor. Once the sphere had collected all the energy it needed, it would pass the excess to another larger Dyson-sphere processor that completely surrounded the first, repeating the process until all of the energy was being used. That's why this theoretical computer is called a Matrioshka brain: the nested Dyson spheres would resemble matryoshka dolls, or Russian nesting dolls. Of course, if you surround your star with Dyson spheres, it would be difficult for life on your planet to continue. That's kind of the point: this Matrioshka brain would be so powerful that a species could upload their entire consciousness into it and live within an alternate universe simulated by the computer. The species itself could die and its planet could be destroyed, but the civilization would live on in a digital world identical to the one it left behind. In fact, many people, including Elon Musk, believe we're living in a simulation like that at this very moment. This provides one answer to the Fermi Paradox—that is, the question of why we haven't encountered aliens despite the likelihood that they're out there. It's possible that any civilization advanced enough to find us has already decided to abandon reality entirely and upload themselves to a Matrioshka brain.

MegaMIMO 2.0 Is The Faster Wi-Fi We All Need

There always seems to be a speed issue when accessing a wireless network in a public place. But thanks to research from MIT, you may soon say goodbye to slow coffeehouse Wi-Fi. Researchers from MIT's Computer Science and Artificial Intelligence Lab (CSAIL) have developed MegaMIMO 2.0, a Wi-Fi system that is three times faster than traditional Wi-Fi and has double the range. Wi-Fi speeds are slow in public places due to interference. If a lot of people are trying to connect to the same internet connection, the speed practically slows to a halt because there isn't enough wireless spectrum available for people to get their data quickly. MegaMIMO 2.0 is designed to juggle multiple access points at once without creating interference. It does this all while remaining on the same frequency. Get more details on this Wi-Fi system, and learn more about Wi-Fi in general, with the videos below.
