Coffee Fun Facts. Math Fun Facts. Did you know that it is possible to cut a solid ball into 5 pieces, and by re-assembling them, using rigid motions only, form TWO solid balls, EACH THE SAME SIZE AND SHAPE as the original?
This theorem is known as the Banach-Tarski paradox. So why can't you do this in real life, say, with a block of gold? If matter were infinitely divisible (which it is not) then it might be possible. But the pieces involved are so "jagged" and exotic that they do not have a well-defined notion of volume, or measure, associated to them. In fact, what the Banach-Tarski paradox shows is that no matter how you try to define "volume" so that it corresponds with our usual definition for nice sets, there will always be "bad" sets for which it is impossible to define a "volume"! Presentation Suggestions: Students will find this Fun Fact hard to believe. The Math Behind the Fact: First of all, if we didn't restrict ourselves to rigid motions, this paradox would be more believable. 9 Most Devastating Insults From Around the World. A responsible traveler won't set foot in another country without knowing how to viciously insult the people in their native language.

Yawn Fun Fact. By Andrew Newburg | Yawn.
Go ahead: Laugh if you want (though you’ll benefit your brain more if you smile), but in my professional opinion, yawning is one of the best-kept secrets in neuroscience. Even my colleagues who are researching meditation, relaxation, and stress reduction at other universities have overlooked this powerful neural-enhancing tool. However, yawning has been used for many decades in voice therapy as an effective means for reducing performance anxiety and hypertension in the throat. Several recent brain-scan studies have shown that yawning evokes a unique neural activity in the areas of the brain that are directly involved in generating social awareness and creating feelings of empathy.
One of those areas is the precuneus, a tiny structure hidden within the folds of the parietal lobe. Why am I so insistent? As a young medical student, I was once “caught” yawning and actually scolded by my professor. My advice is simple. 10 Psychological Experiments That Went Horribly Wrong. Psychology as we know it is a relatively young science, but since its inception it has helped us to gain a greater understanding of ourselves and our interactions with the world.
