All Together Now

First and foremost, congratulations to the mental_floss team for winning its first Webby award for best cultural blog. When Kara and I started putting the first daily content on the blog in September 2002, we had dreams that it would develop into something far beyond what we could dream. We're proud to still be around to see it. And thanks to all you wonderful readers as well!

Good luck with today's math-related Brain Game Tuesday Test Time challenge:

What's the smallest whole number
that has 10 exact divisors
(numbers that can be evenly divided into it)

Here is the ANSWER.


What's the smallest whole number that has 10 exact divisors (numbers that can be evenly divided into it)?


FORTY-EIGHT. It's divisible by 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48.

Thanks for playing! Tomorrow, it's Wordplay Wednesday.

Happy anniversary to my wife Kara, who's put up with me for 19 years. Thanks, hon!

Pop Quiz: See How Well Your Brain Handles the Stroop Test

Our brains are amazing organs. They’re capable of solving highly complex problems and achieving incredible feats. But the brain isn’t perfect. Despite its many strengths, it doesn’t take much to completely confuse it. Case in point: The Stroop effect.

The Stroop effect—named after John Ridley Stroop, who first wrote about it in a psychology paper—illustrates what happens when the brain is trying to process conflicting streams of information. Specifically, the test that produces the effect involves naming the color a word is printed in when the word itself is the name of a different color. (Example: seeing the word “red” in a blue font and saying “blue.") Reading words is easy, naming colors on their own is a bit harder—and when those two things conflict, the brain is sent into a bit of a tizzy.

You can watch the folks over at Science World in British Columbia above as they take the Stroop test, and play along to test your own mental flexibility. Be prepared to feel flustered.

For more about the Stroop effect, head over to Science World’s website.
