This Surfboard Photo Could Be the Next "The Dress" Debate: Do You See Bumps or Grooves?

When a fellow POPSUGAR employee was texting with a group of his surf buddies about this Craigslist ad for a used surfboard, he mentioned to the group that based on this up-close photo of the board, it must be damaged, because it looks like something had eaten away at the surface. He quickly sparked a debate with his friends, who either saw wax bumps or wax-filled grooves. We brought the debate to the office, and the photo created a divide: team bumps or team grooves. And yes, the great dress col...

If You Pay Close Attention to the Math Behind Pizza, You Could End Up Saving Serious Dough

Listen up, pizza-lovers. If you've ever been faced with the conundrum of which size pie to order to get the most bang for your buck, today's your lucky day. Twitter user @fermatslibrary broke down the math behind pizza sizes, and it's blowing people's minds. Turns out that after finding the area of each pie, one 18-inch pizza will actually yield more cheesy goodness than two 12-inch pizzas. This essentially means you'll have more to eat when you order one medium pizza instead of two smalls (or ...

This Christmas Brain-Teaser Is Deceptively Tricky - Can You Solve It?

I love a good brain-teaser, especially ones that challenge me to locate objects hidden in a cluttered picture à la those I Spy books I used to hoard and relentlessly scour back in the day. The latest search-and-find game to circulate the internet puts a fun holiday spin on the concept, challenging viewers to spot five turkeys in a chaotic Christmas scene. Designed by the folks over at Stay in Cornwall, the brain-teaser may sound like a piece of (fruit)cake, but it actually takes most people bet...

Can you figure out what number comes next?

Take a look at the sequence. What number comes next? The answer is a no brainer – once you know the answer, that is. Neil Sloane, founder of the Online Encyclopedia of Integer Sequences, starts explaining the answer at :22, so pause before then if you need more time to figure it out. Extra footage of this video can be found here.

Puzzle - how to ensure you get the quarter, not the penny

From our friends at Futility Closet: Here are a penny and a quarter. Make a statement. If your statement is true, then I’ll give you one of these coins (not saying which). But if your statement is false, then I won’t give you either coin. Raymond Smullyan says, “There is a statement you can make such that I would have no choice but to give you the quarter (assuming I keep my word).” What statement will accomplish that? Answer is here.

This Brain Teaser Will Make You Want to Throw Your Phone in the Trash

View this post on Instagram A post shared by NFINITY8 (@nfinity8dubai) on Aug 26, 2018 at 11:31pm PDT Take a good hard look at this seemingly innocent photo and see if you can figure out just how many number 8s you see.

This Addicting Color Quiz Will Have You Questioning Your Eyesight

Playbuzz is known for its addicting quizzes and games, and this particular one is about to suck you in. It claims to test your vision by showing you colors in the same family and asking you to choose which one is different. We played several times and one time chose the wrong answers on purpose - only to still get the "healthy vision" result. So be warned: it's definitely probably not as accurate as other vision tests out there, but it sure is fun. Have at it! Related: ...

These Connect-the-Dot Puzzles Look a Lot Easier Than They Actually Are

The internet is great at frequently making us feel confused and utterly hopeless with its constant stream of impossible optical illusions and math problems. Yet another example of this is one asking people to complete different tasks, like connecting dots using only a certain amount of lines. While this sounds simple enough, the puzzle's creator maintains that only one in five people can solve all of the puzzles. Think you've got what it takes to be one of the people? Check out the puzzles below...

Can we wrap a 1x1x1 cube with the blue 3x3 piece of paper, cutting along some edges without disconnecting it?

Here's a good puzzle that Clifford Pickover found at CTK Insights: Is it possible to wrap the cube with a 3×3 piece of paper below it? Handling of the paper is subject to two conditions: 1. The paper may be only cut or folded along the crease lines. 2. The cutting should not cause pieces to separate.

Excellent $5 puzzle book: The Moscow Puzzles: 359 Mathematical Recreations

I bought the Dover edition The Moscow Puzzles in 2014, and it's still one of my all-time favorite puzzle books. Here are a few samples: Book description: This is, quite simply, the best and most popular puzzle book ever published in the Soviet Union. Since its first appearance in 1956 there have been eight editions as well as translations from the original Russian into Ukrainian, Estonian, Lettish, and Lithuanian. Almost a million copies of the Russian version alone have been sold. Part...

A hat puzzle

A good puzzle from our friends at Futility Closet: Three logicians walk into a bar. Each is wearing a hat that’s either red or blue. Each logician knows that the hats were drawn from a set of three red and two blue hats; she doesn’t know the color of her own hat but can see those of her companions. The waiter asks, “Do you know the color of your own hat?” The first logician answers, “I do not know.” The second logician answers, “I do not know.” The third logician answers, “Yes.” What is ...

Brain teaser: draw a cross inside the grid

On the latest episode of Scam School, Brian Brushwood presented three old brain teasers. Here's my favorite. Make a five-by-five grid of dots. Then draw a cross by connecting the dots in such a way that five dots are enclosed by the cross and eight dots are outside the cross. The example on the right satisfies the first part (five dots inside the cross) but it fails the second requirement (it has four dots outside, but needs eight.) You can learn the solution by watching the video.

Puzzle: The Candy Thief

A puzzle from our friends at Futility Closet: Five children — Ivan, Sylvia, Ernie, Dennis, and Linda — entered a candy store, and one of them stole a box of candy from the shelf. Afterward each child made three statements: Ivan: 1. I didn’t take the box of candy. 2. I have never stolen anything. 3. Dennis did it. Sylvia: 4. I didn’t take the box of candy. 5. I’m rich and I can buy my own candy. 6. Linda knows who the crook is. Ernie: 7. I didn’t take the box of candy. 8. I didn’t know Linda u...

The best place to sit in a "suicide circle" if you really don't want to die

Math problems are more interesting when they are posed as horror stories. The Josephus Problem gets its name from Titus Flavius Josephus, a first-century Jewish scholar. The story goes that he was with 40 other soldiers when they were surrounded by conquering Romans - imagine that scene in Games of Thrones, where Ramsay Bolton's men trap Jon Snow's army in a tight circle and start moving in. Rather than give themselves up, the soldiers decided to commit suicide en mass, but by killing ea...

The best book of physics brain teasers

I bought Thinking Physics, by Lewis C. Epstein in 1984. It's one of my favorite books of brain teasers. They are designed to help you gain a qualitative, intuitive sense of physics. The author stresses that after you read each of the many charmingly illustrated problems in the book, you should put the book away and take your time running a simulation of the problem in your head. This is great advice. The book is broken up into sections: Mechanics (kinematics, Newton's Law of Motion, momentum a...

The Missing Dollar puzzle from Martin Gardner's Aha! Gotcha book series

Martin Gardner wrote Aha! Gotcha: Paradoxes to Puzzle and Delight and Aha! Insight in the early 1980s and I love them both. Both books have excellent brain teasers with charming illustrations. They are both out of print, which is criminal, but Amazon has used copies for $0.01 (plus $3.99 s&h).
