Here’s some fun for some of you math buffs....but you’d better be good!  

Did you know that....

★    The lapsed time in seconds between seeing a flash of lightning and hearing a thunderbolt is a measure of the distance between the observer and the storm at the rate of 5 seconds per mile.

★    We could approach the speed of light (186,000 miles/second) if we could accelerate continuously through space at the rate of 1g,where g is surface gravity, (32.2 feet/seconds 2<second power>) for 1 year.

★    For any solid figure with polygonal faces, the number of faces (F) plus the number of vertices (V) less the number of edges (E) is always 2.  This is expressed as F+V-E and is called Euler’s formula.

★    Because of a tidal interaction causing the moon to recede from the earth, the earth’s rotation is slowing 23.2 microseconds per year.   This means that in 155 million years, there will be twenty-five hours in a day instead of twenty-four, and the year will have only 350.5 days.

★    Every year that is divisible by 4 is a leap year, except for centennial years that are not divisible by 400.  For example the years 200, 2400 will be leap years but  2100 and 2200 will not.

★    Your heart beats over 2.2 billion times by the time you are 60 years old.

★    The length of a meter is approximately equal to the length of a pendulum that completes a single oscillation in one direction in one second.

★    the universally accepted measure of a time unit- a second - is defined by the radiation frequency of the cesium 133 atom.  This is the time required for the atom to vibrate 9,192,631,770 times.

★    Betelgeuse, the supergiant star in the constellation Orion, has a diameter in excess of 80 AU (astronomical units), making it larger than 9,000 of our suns.  It would fill our solar system past the asteroid belt.

★    The nearest start system, Alpha Centauri, is 4.3 light-years (about 25 trillion miles) from earth.

★    A number is divisible by 3 if the sum of its digits is divisible by 3.

★    Every odd number greater than 7 is the sum of three prime numbers.

★    At a depth (h) in feet below the water surface, the pressure in pounds per square inche is  0.433h.

★    Were Bill Gates of Microsoft to invest his entire $56 billion at 5% (after taxes), it could spend $8,872,716 per day, and it would take him 40 years to exhaust his fortune.

★    A number is divisible by 8 if its last three digits are divisible by 8.
