Prototype Robot With Smartphone to Test 3-D Mapping, Navigation Inside Space Station | NASA
Image Credit: NASA/Ames Orbital Sciences Corporation’s Cygnus spacecraft will carry 3,293 pounds (1,493.8 kg) of cargo on its upcoming commercial resupply mission to the International Space Station, including crew supplies, nanosatellites, student research and this prototype free-flying space robot equipped with a smartphone, known as Smart SPHERES (Synchronized Position Hold, Engage, Reorient Experimental Satellites). NASA…

What’s a Color?
What is color? It seems like a simple question at first, but when you think about it, the reality of what we’re seeing is a pretty complex situation. Our human eyes sift through a small piece of the vast electromagnetic spectrum and translate it into every color of the rainbow. But there are other animals…

First Full 3D Model of Eta Carinae Nebula Created by Nasa Scientists
An international team of astronomers has developed a 3D model of a giant cloud ejected by the massive binary system Eta Carinae during its 19th century outburst. Eta Carinae lies about 7,500 light-years away in the southern constellation of Carina and is one of the most massive binary systems astronomers can study in detail. The…

Algebraic Topology
A first course in Algebraic Topology, with emphasis on visualization, geometric intuition and simplified computations. Given by Assoc Prof N J Wildberger at UNSW. The really important aspect of a course in Algebraic Topology is that it introduces us to a wide range of novel objects: the sphere, torus, projective plane, knots, Klein bottle, the…

Proofing BICEP2
Inflation—the hypothesis that the Universe underwent a phase of superluminal expansion in a brief period following the big bang—has the potential of explaining, from first principles, why the Universe has the structure we see today. It could also solve outstanding puzzles of standard big-bang cosmology, such as why the Universe is, to a very good…

Puffing in Large Scale Interactions
This combination of three wavelengths of light from NASA’s Solar Dynamics Observatory shows one of the multiple jets that led to a series of slow coronal puffs on Jan. 17, 2013. The light has been colorized in red, green and blue. Image Credit: Alzate/SDO A suite of NASA’s sun-gazing spacecraft have spotted an unusual series…

From the Mathematics of Supersymmetry to the Music of Arnold Schoenberg
Published on Jun 28, 2014 https://perimeterinstitute.ca/videos/… The concept of supersymmetry, though never observed in nature, has driven a great deal of research in theoretical physics over the past several decades. Much has been learned through this research, but many unresolved questions remain. This presentation will describe how these questions can lead one down a surprising…

On Superposition
Published on Jun 18, 2014 MIT 8.04 Quantum Physics I, Spring 2013View the complete course: http://ocw.mit.edu/8-04S13Instructor: Allan Adams In this lecture, Prof. Adams discusses a series of thought experiments involving “box apparatus” to illustrate the concepts of uncertainty and superposition, which are central to quantum mechanics. The first ten minutes are devoted to course information.…

LHC Sound
Sonification is the process of creating sounds that carry information. Musical compositions carry information in the sense that they often describe a place, a time or a feeling; the associations we make between sonic properties such as pitch and physical properties such as speed or size, come to us without effort. The grand aim of…

What is Your Theory On Blackhole Radiation?
MSU Professor Chris Adami has found the solution to a long-standing problem with Stephen Hawking’s black hole theory. In a groundbreaking study recently published in the journal Classical and Quantum Gravity, Adami found that various types of information, as specific as matter or particles, or as obscure as the contacts in your mobile phone or…

Black holes, quantum information, and the foundations of physics
Volume 66, Issue 4, April 2013 Quantum mechanics teaches that black holes evaporate by radiating particles—a lesson indicating that at least one pillar of modern physics must fall. See: Black holes, quantum information, and the foundations of physics by Steven B. Giddings, in Physics Today, April 2013 Based on an image from NASA/CXC/M.Weiss Citation: Phys.…
