mobius strip

You have most likely encountered one-sided objects hundreds of times in your daily life – like the universal symbol for recycling, found printed on the backs of aluminum cans and plastic bottles.

This mathematical object is called a Mobius strip. It has fascinated environmentalists, artists, engineers, mathematicians and many others ever since its discovery in 1858 by August Möbius, a German mathematician who died 150 years ago, on Sept. 26, 1868.

Möbius discovered the one-sided strip in 1858 while serving as the chair of astronomy and higher mechanics at the University of Leipzig. (Another mathematician named Listing actually described it a few months earlier, but did not publish his work until 1861.)…

The discovery of the Möbius strip in the mid-19th century launched a brand new field of mathematics: topology: “The Mathematical Madness of Möbius Strips and Other One-Sided Objects.”

As we return from whence we came, we might wish a Joyeux Anniversaire to Denis Diderot, contributor to and the chief editor of the Encyclopédie (“All things must be examined, debated, investigated without exception and without regard for anyone’s feelings.”)– and thus towering figure in the Enlightenment; he was born on this date in 1713.  Diderot was also a novelist (e.g., Jacques le fataliste et son maître [Jacques the Fatalist and his Master])…  and no mean epigramist:

From fanaticism to barbarism is only one step.

We swallow greedily any lie that flatters us, but we sip only little by little at a truth we find bitter.

Man will never be free until the last king is strangled with the entrails of the last priest.

A thing is not proved just because no one has ever questioned it.

“Archives are a kind of site… like an archaeological site”*…

 

I was told that the most interesting man in the world works in the archives division of the New York Public Library, and so I went there, one morning this summer, to meet him. My guide, who said it took her a year to learn how to get around the Schwarzman Building on 42nd Street, led us to an elevator off Astor Hall, up past the McGraw Rotunda, through a little door at the back of the Rose Main Reading Room. Our destination was Room 328.

A sign above the door called it the “Brooke Russell Astor Reading Room for Rare Books and Manuscripts.” Inside, there were a handful of quiet researchers stooped at large wooden desks, and in the corner, presiding over a cart of acid-free Hollinger document boxes, was the archivist Thomas Lannon…

The New York Public Library’s archives contain dentures, roller skates, and, as David Grann discovered, evidence of a systematic campaign of murder; Thomas Lannon presides over it all: “Keepers of the Secrets.”

As we dig through the files, we might wish a Joyeux Anniversaire to Denis Diderot, contributor to and the chief editor of the Encyclopédie (“All things must be examined, debated, investigated without exception and without regard for anyone’s feelings.”)– and thus towering figure in the Enlightenment; he was born on this date in 1713.  Diderot was also a novelist (e.g., Jacques le fataliste et son maître [Jacques the Fatalist and his Master])…  and no mean epigramist:

“Share your knowledge. It is a way to achieve immortality.”*…

 

As of earlier this week, the English-language Wikipedia contains 4,985,975 articles. If these were printed and bound into books — each 25cm tall by 5cm thick, like Britannica — there would be 2,207 volumes, each containing 1,600,000 words…

All of this content is, of course, user-submitted. It is also user-policed: the site requires constant maintenance from a massive pool of unpaid editors, who do things like fix typos, remove instances of vandalism (like de-categorizing George W. Bush as a “sexually-transmitted disease”), and improving the breadth and accuracy of each and every page.

Of Wikipedia’s 26 million registered users, roughly 125,000 (less that 0.5%) are “active” editors. Of these 125,000, only some 12,000 have made more than 50 edits over the past six month. And of these selfless few, one man is king of the domain.

Since joining Wikipedia a decade ago, 32-year-old Justin Anthony Knapp (username “koavf”) has established himself as the the site’s most active contributor of all time. He has made an astonishing 1,485,342 edits (an average of 385 per day), ranging in topic from Taylor Swift to the history of blacksmithing.

What’s life like as Wikipedia’s most prolific editor? And what has compelled this man to dedicate thousands of hours of his time, knowledge, and energy to an online encyclopedia for absolutely no compensation?…

As we contribute to the commonweal, we might recall that it was on this date in 1760 that Denis Diderot, Enlightenment paragon and co-founder, chief editor, and contributor to the Encyclopédie, wrote to his friend Sophie Volland of the very phenomenon that koavf has devoted so much of his life to avoiding…

Diderot transcribed the words of Galiani, who seized the occasion to shine before his audience: “My friends, I recall a fable. Listen to it.” The story tells of a contest between two birds of different species, the cuckoo (supposed to be the representative of method) and the nightingale (the spokesman of genius). Which voice is more beautiful? The dispute is submitted to the ass for judgment. He is lazy and, without investigating the case or listening to the litigants, declares the cuckoo the winner. The story came from an Italian work, the burlesque epic Ricciardetto (1738), by Niccolò Fortiguerri (1674–1735), which Diderot also knew, having recently read it and found cause in it “to weep alternatively from pain and from pleasure.” The ass’s iniquitous judgment in favor of the cuckoo is a perfect example of resorting to antiphrasis: the good response, in a case of this sort, is obviously the contrary of the one given by a bad judge, that is, a judge who does not listen
