Watch This Teenager Set the New Rubik's Cube Speed Record

The world record for least time spent solving a standard Rubik’s Cube is now officially under five seconds, thanks to 14-year-old Lucas Etter. He set the new record at 4.904 seconds this past Saturday at Clarksville, Maryland’s River Hill Fall competition. His speedy achievement has since been recognized by Guinness World Records and the World Cube Association.

Fellow teenager Collin Burns set the old record of 5.25 seconds during a World Cubing Association competition in Doylestown, Pennsylvania earlier this year. At the same event Etter attended this weekend, one of his competitors shaved .16 milliseconds off that time when he solved a Rubik’s Cube in 5.09 seconds. That time was never officially recognized as the new record, however, as Etter was able to best him before the day’s end.

While Etter is now recognized as the Rubik’s Cube record holder of the human world, the true distinction may arguably belong to a robot. In 2014, a “speedcuber” robot built from LEGO blocks was able to solve a cube in 3.253 seconds. It may take a while for humans to beat that record, but Etter can take comfort in knowing that he’s faster than at least one Rubik’s Cube-solving robot—and he only used two hands.

The Victorians loved a good parlour game. Charades and blind man’s bluff were well known enough in the 19th century to find their way into Dickens’ novels, and besides those there were always games like Are You There, Moriarty? and Reverend Crawley to help pass a rainy Victorian afternoon. But when they weren’t trying to guess who was hiding a slipper behind their back or snatching some scalding-hot raisins out of a bowl of burning brandy, the Victorians also had an appetite for word games, riddles and logic puzzles, countless anthologies of which were published at the time.

So how would you get on pitting your wits against these five classic Victorian riddles? Answers at the foot of the page.

1. THE BISHOP OF WINCHESTER’S RIDDLE

The son of anti-slavery campaigner William Wilberforce, Samuel Wilberforce became Bishop of Oxford in 1845 before being elected Bishop of Winchester in 1869. Best known in his day for his opposition to Charles Darwin and for an obsequious manner that earned him the nickname “Soapy Sam” (and famously led to Prime Minister Benjamin Disraeli describing him as “unctuous, oleaginous, saponaceous”), Wilberforce was also a prolific writer of riddles—arguably the most well known of which was as follows:

I have a large Box, with two lids, two caps, three established Measures, and a great number of articles a Carpenter cannot do without. Then I have always by me a couple of good Fish, and a number of a smaller tribe, beside two lofty Trees, fine Flowers, and the fruit of the indigenous Plant; a handsome Stag; two playful animals; and a number of smaller and less tame Herd. Also two Halls, or Places of Worship, some Weapons of warfare, and many Weathercocks. The Steps of an Hotel; The House of Commons on the eve of a Dissolution; Two Students or Scholars, and some Spanish Grandees, to wait upon me. All pronounce me a wonderful piece of Mechanism, but few have numbered up the strange medley of things which compose my whole.

What is being described here?

2. “CAPTAIN OF A PARTY SMALL”

A collection of puzzles entitled A New Riddle Book For The Amusement and Instruction of Little Misses and Masters was published in England, sometime in the mid-19th century, by an author known only as “Master Wiseman.” Among the dozens of puzzles contained in the collection was this classic riddle about “the captain of a small party,” the original version of which is thought to date back to the 18th century. What is being described?

I’m captain of a party small,
Whose number is but five;
But yet do great exploits, for all,
And ev’ry man alive.

With Adam I was seen to live,
Ere he knew what was evil;
But no connexion have with Eve,
The serpent or the devil.

I on our Saviour’s Laws attend,
And fly deceit and vice;
Patriot and Protestant befriend,
But Infidels despise.

Matthew and Mark both me have got;
But to prevent vexation,
St. Luke and John possess me not,
Tho’ found in ev’ry nation.

3. HALLAM’S RIDDLE

First published in 1849, this famous riddle was at some point credited to just about every major 18th and 19th century writer from Richard Brinsley Sheridan to Lord Byron, but the name by which it became best known was that of the English historian and legal scholar Henry Hallam. In actual fact, the puzzle is now believed to have been the work of Dr Edward Denison, Bishop of Salisbury from 1837–1854, and given its religious overtones is now also known as “The Bishop’s Riddle.” What is being described here?

I sit on a rock whilst I’m raising the wind,
But, the storm once abated, I’m gentle and kind;
I’ve kings at my feet who await but a nod,
To kneel in the dust on the ground I have trod;
Tho’ seen to the world, I’m known to but few,
The Gentile deserts me, I’m pork to a Jew;
I never have passed but one night in the dark,
And that was with Noah alone in the Ark;
My weight is three pounds, my length is a mile,
And when I’m discovered, you’ll say with a smile—
That my first and my last are the pride of this isle.

4. PLAYING CHICKEN

Published in 1890, One Thousand And One Riddles With A Few Thrown In was an anonymous collection of poems and logic puzzles, many of which took the form of seemingly simple single-line questions. “Which of the feathered tribe would be supposed to lift the heaviest weight?” asked on such question—the answer to which, of course, was the crane.

One of the collection’s trickiest and least obvious challenges, however, was this bizarre brainteaser that you’ll have to be well versed in Shakespeare in order to work out:

Who killed the greatest number of chickens?

5. ROSSETTI’S PROBLEM

The poet Christina Rossetti is arguably best known for her sonnet Remember, and for the lyrics to the Christmas carol In the Bleak Midwinter. But besides her poetry Rossetti was also a prolific writer of riddles, many of which were published in children’s nursery books and anthologies in the mid 19th century. Among the dozens of riddles Rossetti published is this one:

There is one that has a head without an eye,
An there’s one that has an eye without a head:
You may find the answer is you try;
And when all is said,
Half the answer hangs upon a thread!

SOLUTIONS

1. THE HUMAN BODY. Each section (flagged by each capitalized word) in the Bishop’s description is a somewhat cryptic clue to a different part of the body. The “large box,” for instance, is the chest. The “lids” and “caps” are the eyelids and the kneecaps. The “three established measures” are the nails (which a carpenter also couldn’t do without), the hands, and the feet, each of which is the name of a unit of measurement. The “soles” of the feet and the “mussels” of the body are the “good fish” and the “smaller tribe” of creatures. The “two lofty trees” are the palms, while the “fine flowers” are the irises and the tulips (i.e. two lips). The “indigenous plant” is a clue to the hips (i.e. rosehips); the “handsome stag” is a clue to the heart (i.e. hart); and the “two playful animals” are the calves. Hares and hairs are played on in the reference to “a smaller and less tame herd” of animals, while the “two places of worship” are the temples. The arms and shoulder blades are the “weapons of warfare”; the weathercocks are veins (i.e. vanes); the “steps of an hotel” are the “inn-steps” of the feet; and the “ayes” and “noes” voted in the House of Commons are a reference to the eyes and nose. Lastly, the “two students” are the pupils, and “some Spanish grandees” might be known as the “ten dons.”

2. THE LETTER A. The small party in question are the letters A, E, I, O and U.

3. A RAVEN. The original solution to this problem has been lost, and for many years debate raged as to what the correct answer was. One popular explanation was that the riddle was a clue to the Christian Church, with various Bible verses picked out to explain curious clues like “my weight is three pounds” and my length is a mile.” But that explanation still left certain clues and parts of the verse unexplained. Finally, in 1923, the author and puzzle-setter Henry Dudeney proposed a solution that seemed to answer all parts of the problem: a raven. Ravens were once believed to forecast the weather; they were worshiped and revered by ancient peoples; they’re rarely seen, though familiar to most people; they are forbidden as food in the Old Testament; a pair accompanied Noah on his Ark (where one was left alone after Noah released its mate); they weigh roughly three pounds, and can fly a mile with ease. The first and last letter of the word raven, finally, is RN: the abbreviation of the British Royal Navy, considered the “pride of the British Isles” in the 19th century.

4. CLAUDIUS. In Shakespeare’s Hamlet, the ghost of Hamlet’s father explains that Hamlet’s uncle, Claudius, did “murder most foul.”

5. PINS AND NEEDLES. One has an eye, the other does not—and only a needle can be threaded.
