Paul Otlet's "Universal Book" and Other Amazing Notions

Original image

Paul Otlet was an information scientist working in the late nineteenth and early twentieth centuries. He designed various systems of cataloging and connecting information, including systems that expanded upon those are broadly used today (for example, Otlet's Universal Decimal Classification significantly expanded on the Dewey Decimal System). Among Otlet's credits are the inventions of the term "link" for the notion of documents referencing each other, and his vision of a réseau ("web") of human knowledge. From a Boxes and Arrows article on his achievements:

In 1934, years before Vannevar Bush dreamed of the memex, decades before Ted Nelson coined the term "hypertext," Paul Otlet envisioned a new kind of scholar's workstation: a moving desk shaped like a wheel, powered by a network of hinged spokes beneath a series of moving surfaces. The machine would let users search, read and write their way through a vast mechanical database stored on millions of 3×5 index cards.

This new research environment would do more than just let users retrieve documents; it would also let them annotate the relationships between one another, "the connections each [document] has with all other [documents], forming from them what might be called the Universal Book."

Otlet, together with Henri la Fontaine, created the Mundaneum in 1910, in an effort to gather and classify all world knowledge. The Mundaneum was to be the heart of a "city of the intellect," and sought to break human knowledge down onto 3x5 cards, which would be cataloged using Otlet's Universal Decimal Classification.

These $425 Jeans Can Turn Into Jorts

Opening Ceremony

Modular clothing used to consist of something simple, like a reversible jacket. Today, it’s a $425 pair of detachable jeans.

Apparel retailer Opening Ceremony recently debuted a pair of “2 in 1 Y/Project” trousers that look fairly peculiar. The legs are held to the crotch by a pair of loops, creating a disjointed C-3PO effect. Undo the loops and you can now remove the legs entirely, leaving a pair of jean shorts in their wake. The result goes from this:

To this:

The company also offers a slightly different cut with button tabs in black for $460. If these aren’t audacious enough for you, the Y/Project line includes jumpsuits with removable legs and garter-equipped jeans.

This First-Grade Math Problem Is Stumping the Internet
May 17, 2017

If you’ve ever fantasized about how much easier life would be if you could go back to elementary school, this math problem may give you second thoughts. The question first appeared on a web forum, Mashable reports, and after recently resurfacing, it’s been perplexing adults across social media.

According to the original poster AlmondShell, the bonus question was given to primary one, or first grade students, in Singapore. It instructs readers to “study the number pattern” and “fill in the missing numbers.” The puzzle, which comprises five numbers and four empty circles waiting to be filled in, comes with no further explanation.

Some forum members commented with their best guesses, while others expressed disbelief that this was a question on a kid’s exam. Commenter karrotguy illustrates one possible answer: Instead of looking for complex math equations, they saw that the figure in the middle circle (three) equals the amount of double-digit numbers in the surrounding quadrants (18, 10, 12). They filled out the puzzle accordingly.

A similar problem can be found on the blog of math enthusiast G.R. Burgin. His solution, which uses simple algebra, gets a little more complicated.

The math tests given to 6- and 7-year-olds in other parts of the world aren’t much easier. If your brain isn’t too worn out after the last one, check out this maddening problem involving trains assigned to students in the UK.
