Amazing Calculations

Dear Sisters and Brothers

 

Look at these amazing calculations:

 

1) 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.

 

2) 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.

 

3) 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.

 

4) 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.

 

5) 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.

 

6) Your heart beats over 2.2 billion times by the time you are 60

years old.

 

7) 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.

 

8) 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.

 

9) 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.

 

10) The nearest start system, Alpha Centauri, is 4.3 light-years

(about 25 trillion miles) from the earth.

 

11) A number is divisible by 3 if the sum of its digits is divisible

by 3.

 

12) Every odd number greater than 7 is the sum of three prime

numbers.

 

13) At a depth (h) in feet below the water surface, the pressure in

pounds per square inche is 0.433h.

 

14) 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.

 

15) A number is divisible by 8 if its last three digits are

divisible by 8.
