Recent developments in online learning have increasingly democratized the exchange of information in higher education: the launch of University of the People, a tuition-free online university; Khan Academy's acquisition of SmartHistory and its growing emphasis on humanities and liberal arts; the University of Reddit's crowd-sourced lessons being taught in real-world classrooms; Skillshare creating a community marketplace for teachers and students; Lore opening its doors to learners from all walks of life; major institutes in India putting every class lecture on YouTube in English; LectureFox collating together free university lectures from across the web. Of course not everyone is happy with the way things are going.

Engineers at Rose Hulman design a pretty cool prosthetic arm for a kid according to his specs (4min, video). Looks like it's part of a program to connect students with kids in need that has produced similar projects in the past.
Many visitors to Boston assume that the Back Bay neighborhood is one of the city's oldest. It's actually one of the newest, reclaimed from Charles River marshland at the end of the 19th Century. Before the completion of this project, Beacon Street to Brookline was the top of a tidal dam. Today's Boston Proper is actually mostly fill: in 1630, Boston was 783 acres of land. By 1901, it was 1,904 acres. Filling in Back Bay was an enormous project, but some valuable lessons were learned decades earlier while filling in the South End.

This stealthy undertaking was not an act of robbery or espionage but rather a crucial operation in what would become an association called UX, for “Urban eXperiment.” UX is sort of like an artist’s collective, but far from being avant-garde—confronting audiences by pushing the boundaries of the new—its only audience is itself. More surprising still, its work is often radically conservative, intemperate in its devotion to the old. Through meticulous infiltration, UX members have carried out shocking acts of cultural preservation and repair, with an ethos of “restoring those invisible parts of our patrimony that the government has abandoned or doesn’t have the means to maintain.” The group claims to have conducted 15 such covert restorations, often in centuries-old spaces, all over Paris. - Wired.com "The New French Hacker-Artist Underground"

When it comes to railways, the British are famous for their colonial legacy of one of the world's most extensive railway networks built across then British India but their lesser known and far grander vision was the Cape to Cairo railway network intended to stretch across the sea of colonial pink on the African continent. Left incomplete due to politics and geography, most of it is still almost as it was built in its day. [more inside]

In February 2011, every teacher in Providence, Rhode Island was pink slipped. Not all 1,926 of them got fired, of course, but with the district facing a $40 million deficit, anything is possible. The district says it needs flexibility, just in case. Every school district in the United States faces its own version of what’s happening in Providence. However, “IMAGINATION: Creating the Future of Education and Work” is focused not on how we got here but rather how we can move forward from here immediately even as the education system continues to struggle.

Saturday August 27 Bill Nye dedicated a solar noon clock he designed. The clock is embedded in the facade of Rhodes Hall. At Solar Noon, when the Sun culminates, that is, reaches its highest point in the sky, the sun-shaped feature will light up. It is the marrying of mechanical and electrical engineering with astronomy. What could be better?

The internet is full of answers, and some of them might even be true. For almost 20 years, the the Newton BBS has been a source of answers to science questions that may be accessed directly via the Web
as well as through telnet (no public telnet access any more, sorry). The Newton BBS "Ask A Scientist" archive has answers from 15 science fields, from astronomy to zoology, for a total of more than 20,000 questions answered. This was covered previously, and the site is aimed at teachers and students from grades K-12, so io9's Ask a Physicist questions (with answers from Dr. Dave Goldberg) might be more engaging.

iPhone 4's reception woes, wherein bridging the area where the metal bands meet (affectionately dubbed "the spot") results in a dramatic loss in signal strength, have been widely covered in the media over the past few weeks. Apple acknowledged the concerns publicly with a letter to customers where they concluded that the issue was not with the phone, but rather that they were being too generous in the way the software communicated signal quality as bars. After an update to iOS, the bars are in fact different but the problems persist. Most recently, Consumer Reports stated it was unable to recommend iPhone 4 because of the significant design flaw, despite listing it as the highest rated overall smartphone they've tested to date. The latest wrinkle in the story has been an open letter to Steve Jobs from Chuck Schumer, yes -- United States Senator from New York Chuck Schumer, in which he questions the adequacy and transparency of Apple's response to customer concerns. Apple will be holding a press conference at 10AM tomorrow in San Francisco to address the matter. [more inside]

Value engineering (also known as Value Analysis) is an approach to cost-effective product development that seems to have had its heyday in the developed world. However, as this recent student project "Value Engineering Project (Tata Nano)" seems to show, it is still popular in the developing world. Comparing this definition of Carlos Ghosn's now famous phrase "Frugal Engineering" with VE's seems to imply "new name; same approach" - understandable since Tata are the leading lights of the Indian Value Engineering society. Is it time for a global revival of interest?
