Numbers Soar Out of this World

 

Space - the final frontier for numbers. The ability of scientists to determine the size of the universe is limited “to the distance light has traveled since the Big Bang.” Distances in space are measured in light years. A light year is the distance that light travels in 365 days or 5.88 trillion miles/9.46 trillion kilometers. Krüger 60 in the Cepheus Constellation is 12.95 light years from our sun. The Milky Way -- the galaxy not the candy bar -- is an estimated 12 billion years old and 100,000 light years wide. Every 250 million years our solar system orbits the Milky Way.

Fun fact - If you multiply 111,111,111 by itself, you get all the digits in both ascending and descending order or 12,345,678,987,654,321.

Measurement, Temperature, and World Time

The advent of the Internet has brought people from around the world together in a way never before experienced. Web surfers and online gamers must now navigate different systems of measurements, temperatures, and time.

To convert a Fahrenheit-based temperature into Celsius, you simply need to subtract 32 from the temperature, multiply the resulting number by 5, and divide the answer by 9. To reverse the process, multiple the temperature by 1.8 and then add 32. The temperature considered to be a normal human body temperature in America - 98.6 degrees is equal to 37 degrees in Celsius.

You’re on holiday from London. A sign states it’s 5 miles to Manhattan, but you have no idea how far that is. To get kilometers from miles, multiply the number of miles by 1.609344.

Your favorite game system has announced it will be shut down for maintenance and upgrades at noon GMT (Greenwich Mean Time) Beginning in 1883, a change was made from mean solar time to Greenwich (England) Mean Time to make a more standardized system of time. At every 15 degrees along the longitude lines, an hour is added to GMT going east and subtracted going west. At noon GMT, it would be 7 a.m. in New York.

Fun fact - In Biblical times, cubits were used to measure. A cubit was equal to the distance between a person’s elbow and the tip of his middle finger. If two people were available, you could determine fathoms by having each of them outstretch his arm and touch fingertips with the other.

This is another example of how numbers play a very significant role in everyday life .
