Scientists Observe New Exotic Phenomena in Photonic Crystals

Topological effects, such as those found in crystals whose surfaces conduct electricity while their bulk does not, have been an exciting topic of physics research in recent years and were the subject of the 2016 Nobel Prize in physics. Now, a team of researchers at MIT and elsewhere has found novel topological phenomena in a different class of systems — open systems, where energy or material can enter or be emitted, as opposed to closed systems with no such exchange with the outside.

This could open up some new realms of basic physics research, the team says, and might ultimately lead to new kinds of lasers and other technologies.

The results are being reported this week in the journal Science, in a paper by recent MIT graduate Hengyun “Harry” Zhou, MIT visiting scholar Chao Peng (a professor at Peking University), MIT graduate student Yoseob Yoon, recent MIT graduates Bo Zhen and Chia Wei Hsu, MIT Professor Marin Soljačić, the Francis Wright Davis Professor of Physics John Joannopoulos, the Haslam and Dewey Professor of Chemistry Keith Nelson, and the Lawrence C. and Sarah W. Biedenharn Career Development Assistant Professor Liang Fu.

ISS Expedition 54 crew land safely in Kazakhstan

Houston TX (SPX) Feb 28, 2018 Three members of the Expedition 54 crew aboard the International Space Station (ISS), including NASA astronauts Mark Vande Hei and Joe Acaba, returned to Earth on Tuesday after months of performing research and spacewalks in low-Earth orbit. Vande Hei, Acaba and cosmonaut Alexander Misurkin of the Russian space agency Roscosmos landed at 9:31 p.m. EST (8:31 a.m. Feb. 28 in Kazakhstan) sout Full article

Heavy metal is in our blood!

Anytime you don’t feel powerful, remember this:

Supergiant stars are beasts! Their life is a fight between gravity pushing in and heat pushing out. They fuse heavier and heavier elements in their core until they get to iron. They can’t fuse any more. Iron absorbs more energy than it returns, so gravity takes over. The star’s core collapses and the star dies in an explosive supernova that outshines its entire galaxy.

The heat of a supernova fuses new elements during the explosion, which are then spread out into space via the nebula remnant. Nebulae are the birthplaces of new stars and solar systems.

The iron in your blood came from one of the most powerful explosions in the universe.

You have something in your blood that can kill stars and build solar systems.

So the other night during D&D, I had the sudden thoughts that:

1) Binary files are 1s and 0s

2) Knitting has knit stitches and purl stitches

You could represent binary data in knitting, as a pattern of knits and purls…

You can knit Doom.

However, after crunching some more numbers:

The compressed Doom installer binary is 2.93 MB. Assuming you are using sock weight yarn, with 7 stitches per inch, results in knitted doom being…

3322 square feet

Factoring it out…302 people, each knitting a relatively reasonable 11 square feet, could knit Doom.

Should make a Webbinar about it

Webb 101: 10 Facts about the James Webb Space Telescope

Did you know…?

1. Our upcoming James Webb Space Telescope will act like a powerful time machine – because it will capture light that’s been traveling across space for as long as 13.5 billion years, when the first stars and galaxies were formed out of the darkness of the early universe.

2. Webb will be able to see infrared light. This is light that is just outside the visible spectrum, and just outside of what we can see with our human eyes.

3. Webb’s unprecedented sensitivity to infrared light will help astronomers to compare the faintest, earliest galaxies to today’s grand spirals and ellipticals, helping us to understand how galaxies assemble over billions of years.

4. Webb will be able to see right through and into massive clouds of dust that are opaque to visible-light observatories like the Hubble Space Telescope. Inside those clouds are where stars and planetary systems are born.

5. In addition to seeing things inside our own solar system, Webb will tell us more about the atmospheres of planets orbiting other stars, and perhaps even find the building blocks of life elsewhere in the universe.

6. Webb will orbit the Sun a million miles away from Earth, at the place called the second Lagrange point. (L2 is four times further away than the moon!)

7. To preserve Webb’s heat sensitive vision, it has a ‘sunshield’ that’s the size of a tennis court; it gives the telescope the equivalent of SPF protection of 1 million! The sunshield also reduces the temperature between the hot and cold side of the spacecraft by almost 600 degrees Fahrenheit.

8.  Webb’s 18-segment primary mirror is over 6 times bigger in area than Hubble’s and will be ~100x more powerful. (How big is it? 6.5 meters in diameter.)

9.  Webb’s 18 primary mirror segments can each be individually adjusted to work as one massive mirror. They’re covered with a golf ball’s worth of gold, which optimizes them for reflecting infrared light (the coating is so thin that a human hair is 1,000 times thicker!).

10. Webb is so sensitive, it could detect the heat signature of a bumblebee at the distance of the moon, and can see details the size of a US penny at the distance of about 40 km.

BONUS!  Over 1,200 scientists, engineers and technicians from 14 countries (and more than 27 U.S. states) have taken part in designing and building Webb. The entire project is a joint mission between NASA and the European and Canadian Space Agencies. The telescope part of the observatory was assembled in the world’s largest cleanroom at our Goddard Space Flight Center in Maryland.

Webb is currently being tested at our Johnson Space Flight Center in Houston, TX.

Afterwards, the telescope will travel to Northrop Grumman to be mated with the spacecraft and undergo final testing. Once complete, Webb will be packed up and be transported via boat to its launch site in French Guiana, where a European Space Agency Ariane 5 rocket will take it into space.
