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: 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: 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!

Solve it Sundays: Absolutely Nothing

Solve it Sundays: Absolutely Nothing

We are back for another Solve it Sundays, and this one I didn’t find too tricky. Good luck! and as always, the answers are in the comments.

 

It is tempting, soothing even, to think of mathematics as a perfect edifice of logic and order. The truth however is that it is an art as well as a science, and it has places where absolutism breaks down.

For this example, we will show that 0 = 1. Firstly, however, I should point out that when adding a series of numbers, the associative law says that you may bracket the sums as you like without any effect.

1+2+3 = 1+ (2+3)= (1+2) + 3.

So, with that established, consider adding an infinite number of zeroes. No matter how much nothing you gather, you will still always have nothing.

0 = 0+0+0+0+0+…

Since 1-1 = 0, you can replace each zero in your sum, like so:

0 = (1-1)+(1-1)+(1-1)+(1-1)+(1-1)+…

From the associative law, you may arrange the brackets in your sum as you see fit. Which means:

0 = 1+(-1+1)+(-1+1)+(-1+1)+(-1+1)+(-1+1)+…

However, as established, (-1+1) = 0, so this sequence can also be stated as:

0 = 1+0+0+0+0+0+…

Or, for simplicities sake:

0 = 1

Something is clearly incorrect. But what?

Solve It Sundays: Bodies in Motion

Solve It Sundays: Bodies in Motion

So before I get into the puzzle, I wanted to introduce a new segment I wanted to start. I bought a book a few years ago called Einstein’s Puzzle Universe and I really enjoyed trying to solve the riddles, and I thought some of you would too.

Now you’re probably thinking, OH, it’s Einstein, there’s no way I can solve his riddles, he was a genius. Well that may be true for some of the riddles, but most of them can be solved with a bit of applied brain power! Good luck with them, and let me know what you think, or if you think you know the answers, let me know!

I WILL ADD THE ANSWERS IN THE COMMENTS SECTION, SO DON’T SCROLL DOWN THERE IF YOU DON’T WANT THE ANSWERS.

We are used to the idea, that it is possible to sit still, and pass time in a motionless manner. But this amazing planet of ours is very far from static. At all times, we are hurtling through the gulfs of space at astonishing velocities.

It may seem to casual thought that from the Sun’s viewpoint, all of Earth’s population is moving at the same speed. After all, our planet revolves around it at a steady 30km per second – anticlockwise, if we are looking from above the North Pole. However, there is another factor to consider. The Earth spins on its axis as it rotates, at a speed of around 28km per minute, if you are at the equator.

You know, of course, that from the surface of the planet, the Sun appears to rise in the east. So, are you moving more swiftly during the day, or at night?

I’ve found the best way to solve some of these puzzles is to imitate them, at least to a certain extent. Obviously you don’t have a planet in your back pocket, but I’m sure you have a few roundish shaped objects laying around you can use.

Let me know in the comments if you figured out the answer, and remember, DON’T SCROLL PAST THIS UNTIL YOU’VE SOLVED IT, OR HAVE GIVEN UP. Spoiler warning below.
