Enormous black hole streaking through space — Astronomers have spotted quasar 3C 186 thirty six thousand light years away from the center of its galaxy, seemingly trying to escape.
This quasar seems to be rushing away at around 2000 kilometers per second (4.5 million miles per hour) instead.
~ That’s inconceivably fast. Let’s hope it’s trajectory is mathematically away.
A rocket to Mars cost less to get there than making the film The Martian — Ipsita Agarwal via Backchannel retells the story of how India’s underfunded space organization, ISRO, managed to send a rocket to Mars for much less than it cost to make the movie The Martian, starring Matt Damon. “While NASA’s Mars probe, Maven, cost US$651 million, the budget for this mission was US$74 million,” Agarwal writes.
~ Well if you think that’s bad, imagine how much it would cost to send Matt Damon to Mars.
Quantum Computing might finally have a use: chemistry — Simulations of molecules and chemical reactions to aid research into things like new materials, drugs, or industrial catalysts are not new, and account for a significant proportion of the workload of the world’s supercomputers. Yet the payoffs are limited because even the most powerful supercomputers cannot perfectly re-create all the complex quantum behaviors of atoms and electrons in even relatively small molecules, says Alan Aspuru-Guzik, a chemistry professor at Harvard. He’s looking forward to the day simulations on quantum computers can accelerate his research group’s efforts to find new light-emitting molecules for displays, for example, and batteries suitable for grid-scale energy storage.
~ And even less lab explosions.
AI is better at lip reading — Scientists at Oxford say they’ve invented an artificial intelligence system that can lip-read better than humans. The system, which has been trained on thousands of hours of BBC News programs, has been developed in collaboration with Google’s DeepMind AI division.
Watch, Attend and Spell, as the system has been called, can now watch silent speech and get about 50% of the words correct. That may not sound too impressive — but when the researchers supplied the same clips to professional lip-readers, they got only 12% of words right.
~ Well, I still reckon it’s going to be hard to get people to write words on their lips.
Massive artificial sun — An enormous machine looks like an insect’s eye uses 149 lamps to simulate sunlight, making it a handy tool for testing things like solar panels or generating clean energy. Scientists threw the switch on the world’s largest artificial sun on Thursday, which happened to be the birthday of the fellow who designed it, who had tears in his eyes.
~ Please point it at England. Oh, wait, Brexit …
Robot solves uncertainty — A human wearing a headset stands in front of a Brown University robot, which sits on a table with six objects in front of it. The human points at, say, a bowl, and asks, “Can I have that bowl?” A Microsoft Kinect atop the robot’s head tracks the movement of the hand to determine which object the subject means and combines that data with the vocal command. But two bowls are sitting right next to each other, and Iorek can’t differentiate which one the human wants. So it hovers an arm over the bowl it thinks the human wants and asks: “This one?” If the subject says no, the robot determines that its master seeks the other. That may seem like a simple interaction, something a child could do. But this is huge for a robot because the system solves a nasty problem: uncertainty.
~ OK, it can have my damn job, then.
