Currents and Phases in Quantum Rings
-------------------------------------------------
Emergent phenomena in quantum systems often exhibit magnetic signatures. In this talk, I will describe how to use the current in a ring to access fundamental and topological properties of quantum states of charge-carrying particles. Applying a magnetic flux through a ring creates a phase gradient, in response to which a current flows, creating magnetic fields that we measure with a scanning SQUID microscope. I will take you on a tour of currents and phases in common and exotic quantum materials. Gold rings are normal metals with finite resistance down to the lowest measured temperatures. Remarkably, they nevertheless carry currents that flow forever (called persistent currents), whose sign and magnitude are a test of quantum theories of disordered metals. Aluminum rings superconduct at low temperatures, and are an ideal model system to study superconducting fluctuations. The strong agreement of theory and experiment in conventional metals and superconductors sets the stage to study superconducting rings interrupted by a single Josephson junction. This geometry allows us to measure a fundamental and informative property of the junction, called the current-phase relation. In junctions made of topological materials, the current could theoretically be 4pi-periodic rather than 2pi-periodic as a function of the phase winding in the ring. I will report on progress towards this smoking-gun signature for Majorana modes.

Lisette Oropesa, Marisa Martinez, And More! | Episode 707 | Art RocksPublic Broadcasting!
Louisiana native Lisette Oropesa is charming audiences in premier opera houses around the world. During a recent guest performance in Baton Rouge, the highly regarded soprano discussed the path that led her to operatic heights. The influence of Mayan ancestral roots is evident in the multi-media artwork of Minnesota artist Marisa Martinez. Then, we meet Suzanne Wallace Mears of Oklahoma City, also a mixed-media artist whose wit is reflected in her contemporary works. Closer to home, in Houston, Texas, photographer Peter Molick now uses drone technology to capture “Space City” from above.
First Lensman by E. E. Doc Smith
The Secret Planet. No human had ever landed on the hidden planet of Arisia. A mysterious space barrier turned back both men and ships. Then the word came to Earth, Go to Arisia!, Virgil Samms of the Galactic Patrol went--and came back with the Lens, the strange device that gave its wearer powers no man had ever possessed before. Samms knew the price of that power would be high. But even he had no idea of the ultimate cost, and the weird destiny waiting for the First Lensman.

Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago.
Learning by listening is a great way to:
- increases imagination and understanding
- improves your listening skills
- improves your own spoken accent
- learn while on the move
- reduce eye strain
Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

SUMMARY
=======
The Arts and Crafts movement was an international trend in the decorative and fine arts that began in Britain and flourished in Europe and North America between about 1880 and 1920, emerging in Japan in the 1920s as the Mingei movement. It stood for traditional craftsmanship using simple forms, and often used medieval, romantic, or folk styles of decoration. It advocated economic and social reform and was essentially anti-industrial. It had a strong influence on the arts in Europe until it was displaced by Modernism in the 1930s, and its influence continued among craft makers, designers, and town planners long afterwards.The term was first used by T. J. Cobden-Sanderson at a meeting of the Arts and Crafts Exhibition Society in 1887, although the principles and style on which it was based had been developing in England for at least 20 years. It was inspired by the ideas of architect Augustus Pugin, writer John Ruskin, and designer William Morris.The movement developed earliest and most fully in the British Isles and spread across the British Empire and to the rest of Europe and America. It was largely a reaction against the perceived impoverishment of the decorative arts at the time and the conditions in which they were produced.

Auburn Coach Wife Kristi Malzahn Agrees with Match & eHarmony: Men are Jerks
My advice is this: Settle! That's right. Don't worry about passion or intense connection. Don't nix a guy based on his annoying habit of yelling Bravo! in movie theaters. Overlook his halitosis or abysmal sense of aesthetics. Because if you want to have the infrastructure in place to have a family, settling is the way to go. Based on my observations, in fact, settling will probably make you happier in the long run, since many of those who marry with great expectations become more disillusioned with each passing year. (It's hard to maintain that level of zing when the conversation morphs into discussions about who's changing the diapers or balancing the checkbook.)
Obviously, I wasn't always an advocate of settling. In fact, it took not settling to make me realize that settling is the better option, and even though settling is a rampant phenomenon, talking about it in a positive light makes people profoundly uncomfortable. Whenever I make the case for settling, people look at me with creased brows of disapproval or frowns of disappointment, the way a child might look at an older sibling who just informed her that Jerry's Kids aren't going to walk, even if you send them money. It's not only politically incorrect to get behind settling, it's downright un-American. Our culture tells us to keep our eyes on the prize (while our mothers, who know better, tell us not to be so picky), and the theme of holding out for true love (whatever that is—look at the divorce rate) permeates our collective mentality.
Even situation comedies, starting in the 1970s with The Mary Tyler Moore Show and going all the way to Friends, feature endearing single women in the dating trenches, and there's supposed to be something romantic and even heroic about their search for true love. Of course, the crucial difference is that, whereas the earlier series begins after Mary has been jilted by her fiancé, the more modern-day Friends opens as Rachel Green leaves her nice-guy orthodontist fiancé at the altar simply because she isn't feeling it. But either way, in episode after episode, as both women continue to be unlucky in love, settling starts to look pretty darn appealing. Mary is supposed to be contentedly independent and fulfilled by her newsroom family, but in fact her life seems lonely. Are we to assume that at the end of the series, Mary, by then in her late 30s, found her soul mate after the lights in the newsroom went out and her work family was disbanded? If her experience was anything like mine or that of my single friends, it's unlikely.
And while Rachel and her supposed soul mate, Ross, finally get together (for the umpteenth time) in the finale of Friends, do we feel confident that she'll be happier with Ross than she would have been had she settled down with Barry, the orthodontist, 10 years earlier? She and Ross have passion but have never had long-term stability, and the fireworks she experiences with him but not with Barry might actually turn out to be a liability, given how many times their relationship has already gone up in flames. It's equally questionable whether Sex and the City's Carrie Bradshaw, who cheated on her kindhearted and generous boyfriend, Aidan, only to end up with the more exciting but self-absorbed Mr. Big, will be better off in the framework of marriage and family. (Some time after the breakup, when Carrie ran into Aidan on the street, he was carrying his infant in a Baby Björn. Can anyone imagine Mr. Big walking around with a Björn?)
