A history of China in 8m objects - Chaguan

the Cultural Revolution, the decade after 1966 when Mao Zedong unleashed terror on his own country, pitting neighbour against neighbour, students against teachers, children against parents and Red Guard mobs against officials whom Mao despised. More than a million lives were lost, and many more ruined. Centuries-old temples and libraries were smashed to so much rubble and firewood.

Other exhibits recall hardships. One museum in Anren is devoted to the nearly 18m urban youngsters who were banished to the countryside for years of ploughing, hauling manure and digging ditches instead of being educated.

Drawing the wrong lessons about the past can prompt charges of “historical nihilism”, an offence that sees museums punished and careers blighted.

PPE: l'éolien en mer "sabordé", selon France Énergie éolienne
Ils ont promis un triplement de l'éolien terrestre d'ici 2030. Concernant l'éolien en mer, le premier parc sera mis en service au large de Saint-Nazaire durant le quinquennat "et nous lancerons quatre nouveaux appels d'offres", a indiqué Emmanuel Macron. L'exécutif vise ainsi jusqu'à 35,6 gigawatts (GW) de capacités dans l'éolien terrestre en 2028 et jusqu'à 5,2 GW en mer. France énergie éolienne estime que le déploiement de l'éolien en mer est ainsi "sabordé". "Avec des objectifs réduits de moitié par rapport aux recommandations de la filière, le gouvernement renonce au potentiel énergétique et industriel de cette énergie", estiment les professionnels.

How Do You Take a Picture of a Black Hole? With a Telescope as Big as the Earth - The New York Times
near the core, that fog forms a great glowing Frisbee that rotates around a vast dark sphere. This is the supermassive black hole at the core of the Milky Way, the still point of our slowly rotating galaxy. We call it Sagittarius A*, that last bit pronounced “A-star.” The black hole itself is invisible, but it leaves a violent imprint on its environment, pulling surrounding objects into unlikely orbits and annihilating stars and clouds of gas that stray too close.

the inaugural run of the Event Horizon Telescope (E.H.T.), a virtual Earth-size observatory designed to take the first picture of a black hole. The E.H.T. uses a technique known as very long baseline interferometry (V.L.B.I.), in which astronomers at observatories on different continents simultaneously observe the same object, then combine the collected data on a supercomputer. The E.H.T.’s director, Shep Doeleman, a radio astronomer with the Harvard-Smithsonian Center for Astrophysics, likes to call the E.H.T. “the biggest telescope in the history of humanity.” It has the highest resolution of any astronomical instrument ever assembled. It’s sharp enough to read the date on a nickel in Los Angeles from New York, to spot a doughnut on the moon and, more to the point, to take a picture of the black hole at the center of our galaxy — or, at least, its shadow.

The effort to get that picture speaks well of our species: a bunch of people around the world defying international discord and general ascendant stupidity in unified pursuit of a gloriously esoteric goal. And in these dark days, it’s only fitting that the object of this pursuit is the darkest thing imaginable.

The physicist Werner Israel put it better when he described a black hole as “an elemental, self-sustaining gravitational field which has severed all causal connection with the material source that created it, and settled, like a soap bubble, into the simplest configuration consistent with the external constraints.”

what a black hole would look like if illuminated by the glow from the superheated matter swirling around it. He did his calculations by feeding punch cards into a primitive computer. He drew the results by hand. His black-and-white images looked like twisted depictions of a black Saturn, with a ringlike accretion disk warped like taffy.

That this shadow might be visible from Earth depended on an astonishing set of circumstances. Earth’s atmosphere happens to be transparent to the electromagnetic radiation — in this case, certain microwaves — shining from the edge of the black hole, even though it blocks radiation of slightly longer and shorter wavelengths. The interstellar gunk lying between Earth and the galactic center also becomes transparent at those frequencies, as do the clouds of superheated matter just outside the black hole, blocking a view of the event horizon. Later in life, Fulvio Melia compared this alignment to the cosmic accidents that give us total solar eclipses. The moon is just the right size, in just the right orbit, at just the right distance from Earth that now and then it blocks the sun entirely. Fulvio wasn’t religious, but these coincidences were so unlikely that he couldn’t help but feel that the black-hole shadow was meant to be seen. The universe had arranged for humans to see to the nearest exit.

it’s hard to reconcile two conflicting theories if you can’t find something wrong with either one, and quantum theory, like general relativity, has passed every test. As a result, scientists have been looking for ever-more-extreme situations in which to test these theories. That led them to black holes.

To avoid poisoning one another’s minds — so that no one could accidentally nudge another group into seeing a black-hole shadow that wasn’t really there — these groups worked in isolation, making images using different algorithms and techniques, trying hard to discredit anything that looked too sharp, too clean, too likely to be the product of wishful thinking.

China is trying to turn itself into a country of 19 super-regions - A tale of 19 mega-cities
The concept of city clusters is grounded in the theory of agglomeration benefits, which holds that the bigger the city, the more productive it is. A large, integrated labour market makes it easier for employers to find the right people for the right jobs. As companies gather together, specialised supply chains can take shape. Knowledge also spreads more easily.

L’éolien français manque de souffle

L’énergie éolienne ne fournit aujourd’hui que 4 % de l’électricité française. Lourdeurs administratives et efficacité des recours expliquent cette piètre performance. Le gouvernement tente cependant d’encourager l’essor d’une filière industrielle.

La loi de transition énergétique, votée en 2015, fixe ainsi un objectif d’au moins 22 000 mégawatts (MW) de capacité installée en éolien terrestre à l’horizon 2023, contre 12 000 MW aujourd’hui. Concrètement, pour atteindre cet objectif, il faudra ajouter plus de 4 000 éoliennes aux 6 500 existantes. Mais pour atteindre l’autre objectif de la loi, celui de réduire à 50 % la part du nucléaire dans la production d’électricité, il faudra aller bien plus loin.

« On nous fait poser des Nokia 3310 alors que l’iPhone est déjà disponible, résume un industriel du secteur. Auparavant, on avait quatre mâts de 1 MW chacun, alors qu’aujourd’hui on peut avoir un mât qui produit 4 MW. Mais on ne peut pas les installer puisqu’ils n’existaient pas au moment du dépôt du projet. »

« La complexité joue en faveur de l’Europe. Une éolienne, c’est plus compliqué à fabriquer et surtout à exporter qu’un panneau solaire. »

Grâce à ces modifications, le SER estime que le temps moyen de développement d’un projet d’éolien terrestre en France pourrait descendre à cinq ans – contre sept à dix ans aujourd’hui

Certains y voient même la possibilité de créer une filière industrielle française, après plusieurs faux départs. Siemens Gamesa a ainsi une usine d’éoliennes offshore qui pourrait être prête pour 2019 au Havre (Seine-Maritime), et défend une adaptation du port afin de pouvoir accueillir les gigantesques navires nécessaires à l’installation des éoliennes en mer. General Electric attend également de pouvoir faire fonctionner à plein régime ses usines de Montoir-de-Bretagne (Loire-Atlantique) et de Cherbourg (Manche)… une fois que les projets lancés en 2011 seront confirmés.

What Happens If China Makes First Contact?

Science fiction is sometimes described as a literature of the future, but historical allegory is one of its dominant modes. Isaac Asimov based his Foundation series on classical Rome, and Frank Herbert’s Dune borrows plot points from the past of the Bedouin Arabs. Liu is reluctant to make connections between his books and the real world, but he did tell me that his work is influenced by the history of Earth’s civilizations, “especially the encounters between more technologically advanced civilizations and the original settlers of a place.” One such encounter occurred during the 19th century, when the “Middle Kingdom” of China, around which all of Asia had once revolved, looked out to sea and saw the ships of Europe’s seafaring empires, whose ensuing invasion triggered a loss in status for China comparable to the fall of Rome.

Every so often, a Hans Zimmer bass note would sound, and the glass pane would fill up with the smooth, spaceship-white side of another train, whooshing by in the opposite direction at almost 200 miles an hour.

seti does share some traits with religion. It is motivated by deep human desires for connection and transcendence. It concerns itself with questions about human origins, about the raw creative power of nature, and about our future in this universe—and it does all this at a time when traditional religions have become unpersuasive to many.

China could rightly regard itself as the lone survivor of the great Bronze Age civilizations, a class that included the Babylonians, the Mycenaeans, and even the ancient Egyptians. Western poets came to regard the latter’s ruins as Ozymandian proof that nothing lasted. But China had lasted. Its emperors presided over the planet’s largest complex social organization. They commanded tribute payments from China’s neighbors, whose rulers sent envoys to Beijing to perform a baroque face-to-the-ground bowing ceremony for the emperors’ pleasure.

The ‘time machine’ reconstructing ancient Venice’s social networks
Venice is the perfect city for the experiment because of its wealth of historically important, well-ordered documentation. It was founded in the fifth century AD by citizens of the Roman empire escaping barbarian invaders from the north. Its inhospitable lagoons provided much-needed protection, and its location at the north end of the Adriatic Sea also had strategic advantages. It soon became the most important trading post between Western Europe and the east, bringing it riches and power.

SpaceX's Big Fucking Rocket – The Full Story - Wait But Why
The moon has few natural resources, a 28-day day, and with no atmosphere to either provide protection against the sun during the day or warm things up at night, both day and night become murderous.

We’re currently pretty close to Mars, since the last Mars opposition happened on May 22, 2016. That’s why, if you happen to be an “oh shit there’s a way-too-bright star let me take out my Sky Guide app and figure out which planet that is and then tell everyone I’m with and find that, yet again, no one cares, because everyone is a horrible person” nerd like me, you know that all summer, Mars has been super prominent and bright in our night sky.11 A year from now, Mars will be on the other side of the sun from us, and we won’t see it in our night sky at all.

林惠敏:我们希望书店以后能成为一个文化地标,一道城市里的文化风景。我们希望这里是一个思想交流和思维碰撞的地方。我们曾经设想过,当大家围坐在一起交流的时候,提到某本书上的某个论点,如果大家存在分歧的话,可以马上架上梯子爬到书架顶端,取出那本著作,翻到书里阐述那个问题的一页,然后说:“看,书里多少多少页里是这么写着的”,于是将那段话大声地朗读出来……

Why shouldn't I use include to include my glossary definitions?
Why shouldn't I use \include to include my glossary definitions?

Suppose you've defined all your glossary entries in a file called glossary-defs.tex and you want to use some or all of these entries in your document. The glossaries user guide says that you can use:
\loadglsentries[type]{filename}

to load the file. For example:

\loadglsentries{glossary-defs}
You can also use \input{filename} (e.g., \input{glossary-defs}) but you shouldn't use \include{filename}, despite the number of web pages that suggest you can or should.
Although both \input and \include make TeX read the named file, these two commands aren't equivalent. The first, \input, acts as though the contents of the file were written directly in your document in place of the \input command. The other one, \include, does a lot more than this. It

checks it hasn't been nested;
issues a \clearpage;
writes a line to the main .aux file;
checks if the file should be included or excluded. (See \includeonly and \excludeonly). If it should be included, then it:
creates an associated .aux file that's used instead of the main .aux file while the included contents are being read;
reads the included file;
issues another \clearpage;
sets the values of various counters.
Therefore, if you want to just input the contents of a file, \include is far less efficient than \input, can cause a spurious page break and creates a redundant extra file. So always use either \input or \loadglsentries to load your glossary definitions and only do this in the preamble.

Everyday People in Everyday Asia
“There are many different narratives that come out of Asia, but I’d say two of the big ones are stories of economic gain — people becoming rich, or people getting evicted because of new wealth — or this exoticism, where people say, ‘Oh, look at this really strange and colorful festival they have,’ ” Mr. Jansen-Lonnquist said.

“Even on well-worn paths, we miss things. We overlook,” he said. “I think it’s important to revisit what we assume we know about. In Everyday Asia we can admit that we don’t know everything about Asia and are working through this process of discovery as well.”

Draft: From Zero To Kickstarter In $5k | Need/Want
We decided on a hard cover, so you can throw it in your bag without worrying about it. Super thick paper means when you’re writing a note, it never bleeds through to the next page (this would also be important during scanning!). We also made them the exact size of the iPad mini, as a lot of people will probably be carrying these things together anyway.

We needed to work out how we were going to position this. We’d played around with A/B testing headlines on Facebook with Smart Bedding, but it can get pretty expensive if you want a decent-sized pool of data.

Incidentally, if you’re a product person that ever has trouble explaining flows and communicating ideas to designers and engineers, I can’t recommend spending a few hours learning your way around After Effects highly enough. Being able to mock up exactly how you want things to look and work, in a few minutes, is INVALUABLE!

There seems to be a strong correlation between the quality of a Kickstarter video and how much money that project raises. Because of this, we wanted to make sure our video was decent. This was by far our biggest expense.

A Collage of Chinese Values
http://www.instapaper.com/read/267294859

I think the outside perception of Chinese youth is one of a mass of people with limited individual identity. I came to realize that perception is clearly wrong. Although it can be argued that society in China is becoming more materialistic and selfish, the care and concern for their parents by Chinese youth is something that those in the West could learn from. The ability to rebel and conform simultaneously is something unique to Chinese youth. The desire by Chinese youth to succeed and to grab what opportunities come their way whether that is in education or business is impressive. In the West, even with the current economic difficulties, we have become lazy and complacent.
