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.
