Breathe …is there anything more important?



Wheels, coins, frisbees, manhole covers, DVD's, and buttons, are round.

Balls, BB's, planets, bubbles, and marbles are spherical.

Why are these such special shapes? And why are these things round or spherical?

Why are bubbles spherical? A sphere most efficiently balances the air pressure between the two sides of the soap film. Planets are spherical because the gravitational force compresses matter into a shape that is evenly distributed.

And, why are manhole covers round? There are many answers to this question but the one I like the most is that a round cover is the only shape that will not fall through a round hole. Every other shape could drop into it's diagonal. (Images of manhole cover rubbings here: Christiansen Designs.)

Other facts about circles:

  • Cylindrical containers can hold more volume than square or hexagonal containers made with the same amount of material.
  • Round plates hold more food.
  • A round pizza uses less dough to fill the largest space.
  • A round table gives diners more space for more dishes, as well as, a sense of equality.
