Preparing Humanity for Accelerating Technological Changes

La Universidad de la Singularidad:Silicon Valley, la cuna mundial de la alta tecnología, abrirá este verano la Universidad de la Singularidad, un centro académico único que, financiado entre otros por Google y la NASA, formará a los futuros líderes "para que identifiquen los grandes retos de la humanidad"

Preparing Humanity for accelerating technological change - Nasa & Google

"Singularity University, based on the NASA Ames campus in Silicon Valley, is an interdisciplinary university whose mission is to assemble, educate and inspire a cadre of leaders who strive to understand and facilitate the development of exponentially advancing technologies (bio, nano, info, AI, etc.), and apply, focus and guide these tools to address humanity’s grand challenges."

What's going on? Normally, we expect society to progress, amassing deeper scientific understanding and basic facts every year. Knowledge only increases, right? Robert Proctor doesn't think so. A historian of science at Stanford, Proctor points out that when it comes to many contentious subjects, our usual relationship to information is reversed: Ignorance increases.

More accurate title: Robert Proctor on how lying asshats dilute the truth.

"Education is an admirable thing, but it is well to remember from time to time that nothing that is worth learning can be taught." -- Oscar Wilde

"It's not a "Google killer" -- it does something different. It's an "answer engine" rather than a search engine."

Where Google is a system for FINDING things that we as a civilization collectively publish, Wolfram Alpha is for ANSWERING questions about what we as a civilization collectively know. It’s the next step in the distribution of knowledge and intelligence around the world — a new leap in the intelligence of our collective “Global Brain.” And like any big next-step, Wolfram Alpha works in a new way — it computes answers instead of just looking them up. Wolfram Alpha, at its heart is quite different from a brute force statistical search engine like Google. And it is not going to replace Google — it is not a general search engine: You would probably not use Wolfram Alpha to shop for a new car, find blog posts about a topic, or to choose a resort for your honeymoon. It is not a system that will understand the nuances of what you consider to be the perfect romantic getaway, for example — there is still no substitute for manual human-guided search for that. Where it appears to excel is when

Articolo in inglese della BBC, paragone con Google

Researchers claim that a new web tool - Wolfram Alpha - could be as important as Google.

This free program aims to answer questions directly, rather than display web pages in response to a query like a search engine. Like interacting with an expert, it will understand what you're talking about, do the computation, and then present you with the results. This technique has long been the holy grail of computer scientists who aim to allow people to interact with computers in an instinctive way.

The math people catalog EVERYTHING.

"..Objectivity without transparency increasingly will look like arrogance. And then foolishness. Why should we trust what one person — with the best of intentions — insists is true when we instead could have a web of evidence, ideas, and argument?.."

Interesting post about bloggers, journalism, and how we require the abiliity to peer through an author's thoughts to dig at the sourcs of their [objective] arguments.

David Weinberger explains a phrase he coined: "transparency is the new objectivity."

"Objectivity used be presented as a stopping point for belief: If the source is objective and well-informed, you have sufficient reason to believe. [...] We thought that that was how knowledge works, but it turns out that it’s really just how paper works. [...] Objectivity is a trust mechanism you rely on when your medium can’t do links"

"In fact, transparency subsumes objectivity. Anyone who claims objectivity should be willing to back that assertion up by letting us look at sources, disagreements, and the personal assumptions and values supposedly bracketed out of the report. Objectivity without transparency increasingly will look like arrogance. And then foolishness. Why should we trust what one person — with the best of intentions — insists is true when we instead could have a web of evidence, ideas, and argument? In short: Objectivity is a trust mechanism you rely on when your medium can’t do links. Now our medium can."

THE LAST DAYS OF THE POLYMATH

People who know a lot about a lot have long been an exclusive club, but now they are an endangered species. Edward Carr tracks some down ...  read more »

That is why modern institutions tend to exclude polymaths, he says. “It’s very hard to show yourself as a polymath in the current academic climate. If you’ve got someone interested in going across departments, spending part of the time in physics and part of the time elsewhere, their colleagues are going to kick them out. They’re not contributing fully to any single department. OK, every so often you’re going to get a huge benefit, but from day to day, where the universities are making appointments, they want the focus in one field.”

People who know a lot about a lot have long been an exclusive club, but now they are an endangered species.

“Nowadays people that are called polymaths are dabblers—are dabblers in many different areas,” he says. “I aspire to be an intellectual polygamist. And I deliberately use that metaphor to provoke with its sexual allusion and to point out the real difference to me between polygamy and promiscuity."

In other words: We don't know what we don't know until we know that we don't know it.

Memonic is a relatively new tool for curating collections of information from the web. Memonic's key function is to give users the power to clip sections of websites and build them into a personal collection. Along with the clipping of information, users can add commentary to each item they place into their personal accounts. From Free Technology for Teachers

a free web-based tool that seeks to help you clip out just what you need from your web-based research and organize it in a personally meaningful and helpful way. Memonic allows you to move away from the model of bookmarking sites that contain data you want and instead of snipping that data out of the page and saving it to your Memonic account. If you're doing research on a vacation for instance, you wouldn't bookmark every page you found with interesting content about that vacation. You would use Memonic to clip out the bits that were of interest to you—a specific restaurant review from a restaurant critic page, a landmark you found on the visitor's bureau site you want to visit, some photos of local street performers you'd like to keep an eye out for, and so on. All the things you clip end up in your Memonic inbox, seen below:

25 January 2009 The British Library's head says that deleting websites will make job of historians harder. Historians face a "black hole" of lost material unless urgent action is taken to preserve websites and other digital records, the head of the British Library has warned.

web sites are vanishing at faster rate and efforts must be made to prevent this phenomenon in order to keep today's digital web resources for future generation.

The article examines the notion of archiving exisiting websites on the internet for the fear of loosing not only content, but part of our history. With so many online sites, especially in the age of user generated websites, blogs, forums, the question is which sites should be archived, and how do we decide?

Il responsabile della British Library afferma che la cancellazione dei siti renderà il lavoro degli storici più duro

Seems like we're becoming alert to the fact that the web contains stuff that needs to be saved. Good!

Historians face a "black hole" of lost material unless urgent action is taken to preserve websites and other digital records, the head of the British Library has warned. Just as families store digital photos on computers which might never be passed on to their descendants, so Britain's cultural heritage is at risk as the internet evolves and technologies become obsolete, says Lynne Brindley, the library's chief executive.

ok info~ not the best.

good info not as wasy to use or as informative

website not as appealing

only a list of more websites

No pics, had to click in order to get any information. Time consuming.

Provided additional internet sources to go to.

Too short, basic. Student would probably just copy word for word.

Plain looking. Didn't catch my eye. I wanted a site quick and to the point.

no pictures at all! didn't look interesting.

Needs more details.

info was organized and categorized by topics for easy access

not enough reliable info

時速75km 車間距離40m (75/40=1.67) を保つべし！！

統計データによれば、車間距離40mの時の平均速度は時速72kmですので、「高速道路では40m以上詰めると損をする」あるいは「時速約70km、車間距離40mが渋滞の始まり」と覚えておいていただければいいでしょう。

【鎧を着ている以上盾は必要なかった】 日本では非常に古くから全身鎧が用いられるようになりました。 大鎧（大鎧は板金に漆を塗った積層装甲である小冊を重層構造にしたもので一種のチョバムアーマーでした）が用いられていた当初、例えばヨーロッパはまだ板金鎧を実用化出来ていません。 ちなみに当時の彼らが着ていたのは柔らかい鉄を延ばした針金で作った鎖帷子でした。 【外国人と日本人の体格差について】 ここではヨーロッパとの比較についてですが結論から言いますと戦国以前の日本人と当時同時代のヨーロッパ人とでは体格差はありません。 ヨーロッパでは１９世紀以前はゲルマンなど一部の地域を除き160センチあれば大男でした。一方日本では東国部者などは170センチ台がごろごろいました。

物事には３つの状態がある：不明な状態か、アクションを起こしているか、完了しているか すべては「下書き」に過ぎないと受け入れる。そうしてこそ「やり遂げる」ことができる。 推敲などというものはない 自分のやっていることを理解しているふりをするのは、理解してやっていることに十分近い。だから理解している気になって、とにか くやること。 「先送り」を粉砕せよ。アイディアを１週間以上抱えたままでいるなら、やめること。 何かを完了させるのが大事だから「やり遂げる」のではない。さらに他のことをやり遂げるためだ やり遂げたなら、それは放り出してかまわない 完璧主義を笑い飛ばすこと。それはつまらないし、「やり遂げる」ことの妨げにしかならない 手を動かしていない人は最初から間違っている。自分で手を動かしてはじめて正しい見地に立てる 失敗も「やり遂げた」うちに入る。だから失敗すること。 破壊は、「やり遂げる」ことの一面といっていい 何かアイディアがあって、それをネットに公表しただけなら、それは（何かを実際に作るのに比べて）何かを「やり遂げた」つもりになっているだけ 「やり遂げる」ことは、さらに「やり遂げる」ための動力だ

Carr om Googles och Wikipedias symbios och informationssamhällets misslyckande

Three things have happened, in a blink of history's eye: (1) a single medium, the Web, has come to dominate the storage and supply of information, (2) a single search engine, Google, has come to dominate the navigation of that medium, and (3) a single information source, Wikipedia, has come to dominate the results served up by that search engine.

Wikipedia has come to dominate Google web search results. It often ranks #1 for searches on common topics like Internet and Evolution. Is it true that Wikipedia articles are the very best source of information for all of these topics? Or are we witnessing the effects of a popularity feedback loop, fueled by the principles of least effort, and our tendency to stick with the first and obvious answers? The web link graph is fundamentally a product of socialization, and Google is fundamentally a social search engine. A popularity bias in inherent in all social information systems, leading us all down the same well-trod path. Could it be that, counter to our expectations, the natural dynamic of the web will lead to less diversity in information sources rather than more?

Nicholas Carr questions the internet power of wikipedia & google.

(1) a single medium, the Web, has come to dominate the storage and supply of information (2) a single search engine, Google, has come to dominate the navigation of that medium (3) a single information source, Wikipedia, has come to dominate the results served up by that search engine.
