SuitSat Might Be The Creepiest Satellite Ever

by Amy Shira Teitel, Popular Science


On February 3, 2006, commander Bill McArthur and flight engineer Valery Tokarev stepped outside the ISS for a spacewalk. Cameras gave audiences watching the live feed on NASA TV a view of the men working, half obscured by solar panels. Then the cameras showed a body floating off into space. Tokarev nonchalantly bid adieu to his untethered colleague with an unceremonious “Goodbye, Mr. Smith.” The figure might have looked like a man, but it wasn’t. It was Suitsat, which is perhaps the creepiest satellite of all time.

The story of Suitsat can’t be told without the story of the Orlan spacesuit. Continue reading SuitSat Might Be The Creepiest Satellite Ever

Study reveals substantial evidence of holographic universe

A sketch of the timeline of the holographic Universe. Time runs from left to right. The far left denotes the holographic phase and the image is blurry because space and time are not yet well defined. At the end of this phase (denoted by the black fluctuating ellipse) the Universe enters a geometric phase, which can now be described by Einstein’s equations. The cosmic microwave background was emitted about 375,000 years later. Patterns imprinted in it carry information about the very early Universe and seed the development of structures of stars and galaxies in the late time Universe (far right). Credit: Paul McFadden

A UK, Canadian and Italian study has provided what researchers believe is the first observational evidence that our universe could be a vast and complex hologram. Continue reading Study reveals substantial evidence of holographic universe

D-Wave’s quantum computers take a quantum leap forward, now offer 2,000 qubits

by Joel Hruska, ExtremeTech

Over the past few years, quantum computer manufacturer D-Wave has been rolling out hardware capable of increasingly complex tasks and solving more advanced types of problems. This week, it unveiled a new system capable of entangling up to 2,000 qubits.

The D-Wave 2000Q has 2,048 qubits; a substantial increase over the 1,000-qubit D-Wave 2X. Equally important, the $15 million-dollar computer has a first customer — Temporal Defense Systems, which will use the machine “to solve some of the most critical and complex cyber security problems impacting governments and commercial enterprises.” The terms of the deal also give TDS an upgrade path to future “QPUs” (quantum processing units, natch).

Fooling The Machine

The Byzantine Science of Deceiving Artificial Intelligence

In the early 1900s, Wilhelm von Osten, a German horse trainer and mathematician, told the world that his horse could do math. For years, Von Osten traveled Germany giving demonstrations of this phenomenon. He would ask his horse, Clever Hans, to compute simple equations. In response, Hans would tap his hoof for the correct answer. Two plus two? Four taps. Continue reading Fooling The Machine
