DRIVERLESS CAR

Uber Rolls Out First Driverless Cars

 

 it's kind of a surprise that Uber is planning to roll out its first self-driving cars in the heart of Steel City. But that's evidently the plan, according to a recent report at Bloomberg.  Thanks to three converging rivers, the downtown area is a tangle of narrow bridges, stacked overpasses and barely sublimated Rust Belt aggression. Pittsburgh drivers are in it to win it.

 

BLACK HOLE

 One of the biggest problems when studying black holes is that the laws of physics as we know them cease to apply in their deepest regions. Large quantities of matter and energy concentrate in an infinitely small space, the gravitational singularity, where space-time curves towards infinity and all matter is destroyed. Or is it? A recent study by researchers at the Institute of of Corpuscular Physics (IFIC, CSIC-UV) in Valencia suggests that matter might in fact survive its foray into these space objects and

come out the other side.

the researchers obtained a description of black holes whereby the centre point becomes a very small spherical surface. This surface is interpreted as the existence of a wormhole within the black hole. "Our theory naturally resolves several problems in the interpretation of electrically-charged black holes," Olmo explains. "In the first instance we resolve the problem of the singularity, since there is a door at the centre of the black hole, the wormhole, through which space and time can continue."

. Project Tango – 3D Mapping

Project Tango aims to bring spatial awareness of the world around us to handheld devices. We can navigate to any corner of the world, and yet our devices don’t know the difference between up and down, left and right, or what’s beyond the horizon, since these devices “see” the world in 2D.
With Project Tango, mapping the world in real-time won’t be a problem. Imagine entering a building and as you walk inside it, your smartphone maps everything. The ceiling, floor, walls, and objects on your path.

To get an idea of what we can use this technology for, we will let the magic of movie science show you. Here’s a clip from the movie Prometheus where it shows exactly what Project Tango can be used for.

A giant piece of a recently launched Chinese rocket fell to Earth last night (July 27), blazing a spectacular sky trail that left observers across parts of the western United States slack-jawed.
The dazzling fireball lit up skies over Utah, Nevada, Colorado, Idaho and California about 9:40 p.m. local time Wednesday (12:40 a.m. EDT and 0440 GMT today, July 28), breaking into many bright pieces as it went.

The sky show occurred around the peak of the annual Delta Aquarid meteor shower, but it wasn't caused by bits of comet dust. Rather, experts say, the culprit was the second stage of China's Long March 7 rocket, which launched on its maiden flight June 25.
The 6-ton rocket stage hit Earth's atmosphere at about 18,000 mph (29,000 km/h), said astronomer Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics, also an assiduous satellite tracker.

Our self-driving cars are designed to navigate safely through city streets.

They have sensors designed to detect objects as far as two football fields away in all directions, including pedestrians, cyclists and vehicles—or even fluttering plastic shopping bags and rogue birds. The software processes all the information to help the car safely navigate the road without getting tired or distracted.

The car processes both map and sensor information to determine where it is in the world. Our car knows what street it's on and which lane it's in. Sensors help detect objects all around us. The software classifies objects based on their size, shape and movement pattern. It detects a cyclist and a pedestrian in this case.The software predicts what all the objects around us might do next. It predicts that the cyclist will ride by and the pedestrian will cross the street. The software then chooses a safe speed and trajectory for the car. Our car nudges away from the cyclist, then slows down to yield to the pedestrian.
