Solve it Sunday: Gold Standard

Solve it Sunday: Gold Standard

This question may seem laughable at first glance. I assure you, however, that I have no intention of making sport with you. Simplicity does not always indicate triviality.

Which is heavier – a 1-ton block of wood, or a 1-ton block of gold?

You may assume that both blocks are being weighed on the same weighing apparatus in the same terrestrial location, and that the machine is giving an identical value in both cases.

Good luck with this one! It’s not as simple as you might think it is.

Solve it Sunday: A Curious Thought

Solve it Sunday: A Curious Thought

This one might be a bit trickier than you think. It got me when I first read it, but read it carefully before you think you have the answer.

As always…answers in the comments

It has been said that the ultimate in exclusivity would be to build a house which possessed windows facing south on each of its four sides.

Does this seem a reasonable proposition?

Solve it Sunday: Fibonacci’s Game

Solve it Sunday: Fibonacci’s Game

This mathematical party game was devised in the thirteenth century by the Italian mathematician Leonardo Pisano, known to the modern world as Fibonacci. His work on the mathematical system helped to set up the Renaissance, but the matter we will address here is less weighty.

Between two and nine people sit in a line, and together, they secretly conspire to select one of their number.

This person picks a finger joint of one of their hands, either where their ring is being worn, or where the volunteer nominates as a spot where he or she would like to have a ring.

The volunteer then takes their position in the line, doubles it, adds 5, multiplies by 5, and then adds 10 to the total.

Then the number of the ring-bearing finger across the two hands is counted and added (starting with the left little finger as 1), and the value is multiplied by 10.

Finally a number for the knuckle joint is added on, 1 for the joint nearest the hand, 3 for the tip joint. This gives a final total.

“When the number is announced,” Fibonacci says, “it is easy to pinpoint the ring.”

Can you see how?

Solve it Sunday: Ciphertext

Solve it Sunday: Ciphertext

This is a quote made my Albert Einstein. If you can find it then maybe you’d be able to recognize it. Good luck!

In this puzzle, the challenge is to decrypt a quotation that has been made obscure by the use of a simple cypher. Are you able to work out what it says?

Solve it Sunday: High Wire

Solve it Sunday: High Wire

Are you scared of heights? This riddle is all about high-wire walking. No math involved, just some critical thinking or maybe some random knowledge involved.

An incredible amount of skill, dedication and fitness is required to master the art of high-wire walking. However, when you see such a masterful athlete proceeding to and fro over a dizzying drop armed with nothing more than a long, saggy bar, bear in mind that perhaps the feat is somewhat less insanely risky than it may appear.

Can you say why?

Good luck! I didn’t know the answer to this one, but maybe you can solve it.

Solve it Sunday: Two Pails

Solve it Sunday: Two Pails

There is no math required for this one at all. All it takes is a little memory of elementary school science, which may be worse.

Let me know your answer in the comments.

Imagine that you are in possession of two pails of water. These pails are identical in every significant respect, save that one has a large chunk of wood floating freely inside it, while the other does not. Apart from that disparity, the two are filled precisely to the brim with freshly distilled water.

Which of the pails would be heavier?

Good Luck!

Solve it Sunday: Mashed Quote

Solve it Sunday: Mashed Quote

The puzzle below holds a well-known quotation. Although the words in each line remain in the correct order, all punctuation has been removed, and the lines themselves have been jumbled up.

Are you able to piece the original quotation back together?

LIKE AN HOUR THAT’S RELATIVELY
LIKE A SECOND WHEN
NICE GIRL AN HOUR SEEMS
HOT CINDER A SECOND SEEMS
WHEN YOU ARE COURTING A
YOU SIT ON A RED
ALBERT EINSTEIN

Good luck solving this one… and don’t look it up!
