Solve it Sunday: Infinite Worlds

Hello my dear Sherlocks, Einsteins, and other puzzle solvers. You’re probably all cooped up and sick of your family at this point, and need something to keep morale up.

Well, I got just the thing for you.

As always, the solution to the riddle is in the comments.

The mathematics of infinity can be startlingly beautiful. It can allso be just plain startling.

Consider the natural numbers – 1, 2, 3, 4, etc. They are infinite; any number you can conceive of can be increased. Now consider the even natural numbers – 2, 4, 6, 8, etc. These also obviously extend to infinity.

So if you compare the set of all natural numbers with the set of all even natural numbers, which is larger?

Best of luck to you!!!

Solve It Sunday: Ciphertext

Hello my dear Sherlocks, I have a cipher for you today! A bit different than our normal puzzles, but a tricky one nonetheless.

I hope you enjoy this post, because I had a tough time solving this puzzle. I wasn’t able to do it, unfortunately, so I gave up and looked up the answer.

As always…the answers are in the comments!

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: Tribal Mathematics

Hello everybody, I hope you have your thinking caps on! I’m back for another Solve it Sunday post, and this week is a tricky one.

As always, answer is in the comments, and you think you have the right answer, make a comment of your own.

During the 19th century, a European colonel in Ethiopia recorded a report of an encounter with local tribesmen, from whom he was purchasing cattle.

He wanted seven beasts, at a cost of 22 birr each. Not being numerate, the herder called a local priest to verify the total price.

When he arrived, the priest dug two parallel columns of holes. The right-hand column represented the purchase price, so in the first hole he placed 22 stones, and then halved the number of stones for each subsequent hole, rounding down. This gave him 22, 11, 5, 2 and 1 stone.

The left-hand column then represented the cattle, and in the first hole he placed seven small stones. He then doubled the number of stones for each subsequent hole in the column, so that the holes contained 7, 14, 28, and 112 stones.

Declaring even values to be evil, the priest then went down to the right-hand column and whenever he encountered an even number of stones – the 22 and 2 holes, in this instance – he removed the stones from that hole and its neighbor in the left-hand column – 14, 28, and 112 respectively – into one pile, which he counted out one by one.

They came to 154 birr, which was indeed 22×7.

Indeed, this technique of multiplication will always work for whole numbers, but why?


Think you know the answer: let me know in the comments or on social media!

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

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?

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