Today’s Daily Brain Teaser (Jun 03, 2015)

daily brain teaser

Beauty of the Lake

Though my gray beginnings are not so pretty,

I grow quite well into my beauty.

Alabaster white or black as night,

My grace is known world wide.

I may make my home in the chilly Arctic,

I’m also known well down under,

From North America to South America I may be known to trumpet.

As a female I may Pen my name,

While the males may prefer to pick at a Cob.

But near or far my beauty is known by lore and by myth.

Check Braingle.com for the answer.

Creativity : Children

daily brain teaser

Most people would agree that children are generally more creative than adults. Children draw more, ask more questions and come up with interesting ideas. There are two commonly held theories about why we lose our creativity as we age.

The first theory is that as we age, we become more and more aware of practical constraints such as gravity or economics. Working within these constraints prevents us from fully utilizing our imaginations. We must suspend our disbelief in order to be mentally playful.

The second theory is that our culture socializes creative properties out of people. When we are young we are encouraged to draw and play, but as we get older more emphasis is placed on more cerebral activities such as math and reading. Children are slowly trained that being able to do arithmetic is more important than being creative.

Memory : Alzheimer’s Prevention II

daily brain teaser

Mental exercise is one way to help prevent Alzheimer’s. Another means of prevention is to remain physically fit throughout life. All of the organs in the body benefit from being physically fit, including the brain. One Harvard study of more than 18,000 participants found that people who got the most exercise showed less mental decline than those with sedentary lifestyles.

Physical exercise increases blood flow to the brain and keeps it working efficiently by stimulating the production of neurotrophins. This is especially true for the hippocampus which is the first area of the brain affected by Alzheimer’s disease. This increased blood flow and neuronal efficiency can reduce the natural shrinkage that occurs in the brain as it ages. An average person will lose between 15% and 25% of brain cells by the age of 90. Those people who get the most exercise will be at the bottom of that scale, while those people who never exercise will be at the top of that scale.

Orange Spinning Optical Illusion

Purple orange spiral

Have you ever just had one of those days where you feel like you’re going a little crazy? Yesterday was that day for me, and the illusion I found for today’s post didn’t help much!

Take a look at today’s illusion and ask yourself…is it moving??

Purple orange spiral

If you concentrate on the center of this spinning optical illusion, it doesn’t look like it’s moving much. However, if you look outside of the image it looks as though this optical illusion is spinning! You can get the same effect by slowly moving your eyes back and forth across the image.




Don’t believe that this spinning optical illusion is really stationary? Put your finger on one of the the orange spokes. You’ll see that the orange spoke you choose will still be under your finger when you look back proving that the image is stationary. It’s all just a trick of the eye, and definitely enough to freak you out a little on this early Tuesday morning!

I’m not sure who originally created this spinning optical illusion, but I do know that it was most likely inspired by Professor Akiyoshi Kitaoka, a Japanese professor of psychology. Kitaoka specialized in visual perception and illusions, particularly those involving geometrical shape, brightness, and color. He became well known for his rotating snakes illusion.

If this rotating optical illusion wasn’t quite trippy enough for you, we’ve got lots of great illusions for you to look at! Take a look at these Professor Akiyoshi Kitaoka inspired illusions or this moving tunnel optical illusion!

More than 24,000 mechanical puzzles from Jerry Slocum’s collection have been donated to the Lilly Library and can be seen and handled at the Library during business hours six days each week. There are also dozens of Hands-on-Puzzles for you to solve. Photos and information about the Puzzles and many of Jerry’s articles, lectures and his books are available on the Lilly web site. Slocum Puzzle Collection at the Lilly Library

Jerry Slocum

Jerry Slocum’s lifelong fascination with the history of puzzles led to a conundrum of its own, namely, where do you keep tens of thousands of antique mind-benders? The answer lay in the creation of the Slocum Mechanical Puzzle Collection located at Indiana University’s Lilly Library.

“Mechanical puzzles” are those brain-teasers that must be physically manipulated to achieve a specific outcome, so they are more often complex contraptions than simple jigsaws, or pen-and-paper mind games. Slocum had been collecting mechanical puzzles his whole life, eventually becoming the unofficial authority on physical puzzles with the publication of his 1986 book, Puzzles Old and New. By 2006 he had accumulated over 40,000 mechanical puzzles, thanks in part to the International Puzzles Parties, an annual private get together for mechanical puzzle enthusiasts and traders, which Slocum inaugurated in 1978.

Thus he donated over 30,000 of the puzzles to create the Slocum Mechanical Puzzle Collection in Indiana. In addition to the staggering amount of puzzles, Slocum also donated thousands of books about puzzles. Among the pieces on display (only a few hundred out of the thousands committed) are an archaic Rubik’s Cube with differing sizes of nails on each side, called a “texture cube”; a trick cup that seems normal until its drinker fills it too full and it drains away into the base; and more whimsical roadside amusements like a coke bottle with a wooden arrow through it. There are also countless intricate wooden geometrical curiosities that must be twisted and shifted together and apart.

Today, visitors to the library can actually try out a number of the puzzles and see countless others sitting in displays, just waiting to be solved.
