Bad Stanzas

From William Wordsworth, “Goody Blake and Harry Gill”:

Of waistcoats Harry has no lack,
Good duffle grey, and flannel fine;
He has a blanket on his back,
And coats enough to smother nine.

From Charles Wesley, “On the Sight of a Corpse”:

Ah lovely appearance of Death!
What sight upon earth is so fair?
Not all the gay pageants that breathe
Can with a dead body compare.

From Richard Le Gallienne, “Beauty Accurst”:

The sleepy kine move round me in desire
And press their oozy lips upon my hair,
Toads kiss my feet and creatures of the mire,
The snails will leave their shells to watch me there.

From John Scott of Amwell, “To a Friend, Apprehensive of Declining Friendship”:

Too much in man’s imperfect state
Mistake produces useless pain.–
Methinks, of friendship’s frequent fate
I hear my Frogley’s voice complain.

From Isaac Watts, “On the Sudden Death of Mrs. Mary Peacock”:

Hark! she bids all her friends adieu;
Some angel calls her to the spheres;
Our eyes the radiant saint pursue
Through liquid telescopes of tears.

In The Stuffed Owl, D. B. Wyndham Lewis quotes this anonymous verse:

I always knew what sort of weather
We were going to have,
For Cynthia never wore her feather
When the weather would be bad.

But when the days were warm and bright
Cynthia wore a feather,
Sometimes black and sometimes white,
The colour doesn’t count whatever.

Dinner for One

In humans, each eye has a small blind spot corresponding to the point where the optic nerve leaves the retina. Normally this isn’t noticeable because the brain can fill in the gap with information from the other eye. But by closing one eye and positioning the target at the appropriate angle, it’s possible to invoke the gap deliberately.

“When the famous physiological psychologist Karl S. Lashley was forced to endure an irritating dinner guest, he amused himself by bringing his blind spot over the person’s head, neatly decapitating the person.”

Mazes are designed to be tortuous, so even a published solution can be hard to follow. A “straight-line diagram” dispenses with the windings and converts the essential puzzle in a simple map that’s easy to interpret:

This example summarizes the hedge maze in Barcelona’s Parc del Laberint d’Horta.

The same can be done with any meandering route — many subways have adopted stylized maps that dispense with geography and focus on the order of stops, the most important detail for most commuters.

Flight From Moscow

Russian chess master Alexander Petrov composed this puzzle to commemorate Napoleon’s defeat in 1812:

Currently the emperor stands in Moscow, on h7. The goal is to chase him all the way back to Paris and to checkmate him there. The white knights are Cossack cavalry, and the white bishops are Russian partisans. Given these clues, which square represents Paris?

Small World

Reddit user xilefakamot created this in 2020 — a “topologist’s map of the world.”

It depicts international borders and nothing else — the shapes, sizes, and distances between countries are forsaken in order to present the pattern of their borders as efficiently as possible.

“No calculations per se – I sketched out a series of networks showing which countries bordered each other, then gradually smoothed them out to make the map – all done manually.”

Open and Shut

The French constrained writing group Oulipo invented a new crime they call “plagiarism by anticipation.”

If William Shakespeare writes something, and you later write the same thing, then Shakespeare is guilty of plagiarism for anticipating your idea.

“Thus justice is done, and each is rewarded according to his merit.”

A Bug’s Life

A bicycle has wheels of different sizes. On the rim of each wheel is a bug. As the bike travels, the bug on the smaller wheel traces a large number of small arches, and the bug on the larger wheel traces a smaller number of large arches. On a given bicycle trip, which bug travels the greater distance through space?

Remarkably, they travel the same distance. The arches are cycloids, and one revolution of a wheel produces one cycloid arch of length 8r, where r is the wheel’s radius. With each revolution the wheel travels a distance 2πr along the road. This means that during a bicycle journey of distance D, the wheel makes D/2πr revolutions, and the attending bug’s total distance through space is (D/2πr)(8r) = 4D/π. The rs have dropped out, which means that the size of the wheels doesn’t matter — the length of each bug’s path through space is 4/π times the length of the bicycle journey.
