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.
