“The Wear of English Coins”

More than eleven thousand pounds sterling worth of silver is wasted every year in the course of the circulation of crowns, half-crowns, florins, shillings, and sixpences. One hundred sovereigns of the date of 1820, which were weighed in 1859 by Mr. Miller, showed a loss in weight through the wear of circulation which was estimated at £1 6s. 7d. There is, therefore, more waste produced in the circulation of gold and silver coins than is generally thought of. …

Mr. Miller some years ago made a number of precise experiments, from which it was ascertained that £100 worth of sovereigns lost £3 9s. 8.4d. of their value in a hundred years; similarly £100 worth of half-crowns lost £13 11s. 8.8d.; £100 worth of shillings, £36 14s. 3.1d.; and £100 worth of sixpences lost £50 18s. 9.8d. in value, or more than one-half in the hundred years.

For years, South African miners have been finding disks and spheres like this one. Usually brown or red, the objects can measure up to 10 centimeters in diameter, and like this one they’re often engraved with parallel grooves or ridges.

How could worked artifacts have found their way into mineral deposits that are billions of years old? Did aliens visit southern Africa in the remote past? Or is the region’s geologic history vastly different than we’d imagined?

Neither. Despite their artificial appearance, geologists say the objects arose naturally, probably as concretions as volcanic sediments in the region hardened into pyrophyllite.

To a Thesaurus

O precious codex, volume, tome,
Book, writing, compilation, work,
Attend the while I pen a pome,
A jest, a jape, a quip, a quirk.

For I would pen, engross, indite,
Transcribe, set forth, compose, address,
Record, submit–yea, even write
An ode, an elegy to bless–

To bless, set store by, celebrate,
Approve, esteem, endow with soul,
Commend, acclaim, appreciate,
Immortalize, laud, praise, extol

Thy merit, goodness, value, worth,
Experience, utility–
O manna, honey, salt of earth,
I sing, I chant, I worship thee!

How could I manage, live, exist,
Obtain, produce, be real, prevail,
Be present in the flesh, subsist,
Have place, become, breathe or inhale

Without thy help, recruit, support,
Opitulation, furtherance,
Assistance, rescue, aid, resort,
Favour, sustention, and advance?

Alack! Alack! and well-a-day!
My case would then be dour and sad,
Likewise distressing, dismal, gray,
Pathetic, mournful, dreary, bad.

Though I could keep this up all day,
This lyric, elegiac, song,
Meseems hath come the time to say
Farewell! Adieu! Good-by! So long!

— Franklin P. Adams, collected in Carolyn Wells, The Book of Humorous Verse, 1920

Introduced at the end of the 19th century, hail cannons offered farmers a novel way to protect their crops: They could disrupt the formation of hailstones by blasting sound at approaching storms.

Unfortunately, there’s no scientific evidence that they work. And anyway, if loud sounds can prevent hail, won’t thunder do the work for us?

Market Forces

The following question was a favourite topic for discussion, and thousands of the acutest logicians, through more than one century, never resolved it: ‘When a hog is carried to market with a rope tied about its neck, which is held at the other end by a man, whether is the hog carried to market by the rope or the man?’

The Misfortune Field

One of the most enduring contributions to the [Wolfgang] Pauli legend was the ‘Pauli Effect,’ according to which Pauli could, by his mere presence, cause laboratory accidents and catastrophes of all kinds. Peierls informs us that there are well-documented instances of Pauli’s appearance in a laboratory causing machines to break down, vacuum systems to spring leaks, and glass apparatus to shatter. Pauli’s destructive spell became so powerful that he was credited with causing an explosion in a Göttingen laboratory the instant his train stopped at the Göttingen station.

– William H. Cropper, Great Physicists, 2004

(To exaggerate the effect, Pauli’s friends once arranged to have a chandelier crash to the floor when he arrived at a reception. When he appeared, a pulley jammed, and the chandelier refused to budge.)
