The discovery of the structure of DNA was one of the most important scientific achievements in human history. The now-famous double helix is almost synonymous with Watson and Crick, two of the scientists who won the Nobel prize for figuring it out. But there’s another name you may not know: Rosalind Franklin. Cláudio L. Guerra shares the true story of the woman behind the helix.

2016 Leigh Page Prize Lecture Series, hosted by Yale Department of Physics and Yale Quantum Institute
John Preskill, Richard P. Feynman Professor of Theoretical Physics, California Institute of Technology, “Quantum Information and Spacetime”
Abstract: Aside from enabling revolutionary future technologies, quantum information science is providing powerful new tools for attacking deep problems in fundamental physical science. In particular, the recent convergence of quantum information and quantum gravity is sparking exciting progress on some old and very hard questions.
Shenzhen: A new breed of intellectual property (Part 3) | Future Cities ...
source: WIRED UK 2016年6月21日
In this third episode of our Future Cities strand, we explore how attitudes in Shenzhen about patents and intellectual property differ to those in the West.

In particular, we look at how the evolution of “shanzhai” - or copycat manufacturing - has created an ecosystem that could transform traditional models of business, distribution and innovation. Although, technically, any knock-off goods can be called shanzhai, the word's meaning has recently shifted to refer to electronic goods, and episode three delves behind the scenes of this business culture.
The final part of the series is out next Tuesday June 28, when we’ll be asking to what extent the practices in Shenzhen have the power to revolutionise our world. Subscribe to the WIRED YouTube channel to not miss an episode.
Future Cities is part of a new flagship documentary strand from WIRED Video that explores the technologies, trends and ideas that are changing our world.
RSA Replay: The Path to Living Well by Michael Puett
source: The RSA 2016年4月28日
Professor of Chinese history and philosophy Michael Puett has taken Harvard by storm in recent years, delivering its most popular undergraduate course, and attracting thousands of students to his lectures on the ancient teachings of Confucius, Mencius, Laozi, Zhuangzi and Xunzi.
At the RSA, he invites us to re-examine the impact of Western philosophy on our lives and some of our deepest held assumptions, and to "unlearn" many ideas that inform modern society. The ancient Chinese philosophers show that the key to living well is not by "finding" ourselves and slavishly following a grand plan, as so much of Western thought would have us believe, but rather through a path of self-cultivation and engagement with the world. Believing in a "true self" only restricts what we can become - and tiny changes, from how we think about careers to how we talk with our family, can have powerful impact on our lives and relationships.

Zoos Enrich Our Lives but Cost Animals Their Dignity, Says Bill Nye
source: Big Think 2016年6月14日
Responding to the shooting of a gorilla at the Cincinnati Zoo, Bill Nye says the treatment of animals in zoos is plainly unethical. Yet zoos do have a role in maintaining the health of ecosystems.

Transcript - So recently a four-year-old kid got into a gorilla enclosure in a zoo and the zoo officials decided in the safety of the kid they had to kill the gorilla. So here was an animal that was in his natural habitat in Africa doing his gorillatical thing. And he got captured and ended up in a zoo. And then the guy got shot because some kid crawled into his enclosure. It’s just – there’s no good thing about this. With that said my life was certainly enriched by going to zoos. I learned that even a giraffe could exist was an amazing thing to me. And the smell of the zoo was or is something I’ll never forget. It reminds me of farms, there’s animal excrement that has to be dealt with. And you see how much you have in common with these creatures. Is it ethical? I think we all agree it would be better no if we didn’t have zoos. If we had a way to interact with animals without causing them such hardship. Now the example from my personal experience which really affects me and affects my judgment on this. There was a guy named Ivan who was a gorilla brought to the United States in the 1960s. My recollection is 1962.
And he lived with a family in Tacoma, Washington. And they hung out. The gorilla was at the dinner table and they did gorilla-human interaction things, played games, did stuff. But the guy eventually got to be the 400 pound gorilla in the room and they had to put him in an enclosure in a cage that was concrete. And you could visit him in the B&I Department Store in Tacoma, Washington. And this is in the Pacific Northwest and this guy was a character, a feature, a tourist attraction. And I don’t know – I’m not a primate expert but I looked at Ivan. I looked him in the eye. We had a little meeting behind the glass and the guy wasn’t angry to me so much as bored. Like this sucks, you know, I got a rubber swing. Humans are interesting but it’s really not my deal. He got transferred to the Atlanta zoo and I visited him in the Atlanta zoo and he had it going on man. He had a big enclosure. He had girl gorillas. And you could just tell by the way he was walking around this does not suck. This is cool. That was my interpretation of Ivan’s emotions. I may be completely wrong about this but Ivan grew up with humans. He accepted humans. Humans were as much his pets as he was our pet. And so there was some crossover there that I found really compelling as a human. Read The Full Transcript Here: http://goo.gl/EfDYbN.

James Grant: "The Forgotten Depression of 1921: The Crash That Cured Itself" | Talks at Google

The Forgotten Depression tells of the slump of 1920-21: high unemployment, collapse in commodity prices, upsurge in bankruptcies and sharp break in stock prices. Unlike the Great Depression, the 1920 affair was over in 18 months. What explains its brevity?
