Animal sonar, echolocation, and noise pollution

Whales and dolphins have a tool called echolocation, a sonar which allows them to "see" their prey, even it's internal workings! Noise pollution in the water has a significant effect on whales ability to navigate, hunt, locate their pods, and reproduce.
Echolocating animals have two ears positioned slightly apart. The echoes returning to the two ears arrive at different times and at different loudness levels, depending on the position of the object generating the echoes. The time and loudness differences are used by the animals to perceive direction. With echolocation the bat or other animal can see not only where it's going but can also see how big another animal is, what kind of animal it is, and other features as well. - wikipedia


Many modern submarines use their own sonar a low and mid-frequency sonar is so deafening the pressure waves affect animals on the cellular level, causing the equivalent of "the bends" or decompression sickness. For animals with echolocation this causes sonar function to fail and leaves these animals blind, if they're lucky. What often results is massive beachings (update: court blocks sonar 7/6/06)

Augustus Caesar became the emperor of Rome in…

Augustus Caesar became the emperor of Rome in 27 BC, and he ruled the empire for over forty years. This period of history became known as the time of the "Great Roman Peace" ... In A.D. 80 the Colosseum was finished where battles were reenacted, where gladiators fought, and where crowds were entertained by savage violence entertained by the spectacle of Christians being eaten by lions.

n AD 404 a tragic event finally put an end to the gladiators. A Christian monk named Telemachus entered the arena in Rome and tried to separate two combatants. The crowd went berserk, climbed over the walls into the arena and tore the monk limb from limb. The Emperor Honorius permanently banned all gladiator contests.

The Romans were also known to sentencing Christians to death by play. In a live play, when it came time for a death scene, the real actor would be replaced by the accused and the execution would be performed live on stage.

The rule of 72

The rule of 72 is used to find the number of years it takes to double your money at a given interest rate.

(72/[interest rate]) = years until a principle doubles



So, how long will it take to double your money at eight percent interest? Divide 8 into 72 and you get 9 years.



If you collect 7% on your savings in a little over 10 years the amount will be double what it is today.


The rule of 72 also means that you can determine the time
it takes for a population to double if it is growing at a steady rate by solving this function:

(72/[rate of growth]) = years for population to double

Dedicated fathers in the Antartic

A father Emperor penguin withstands the Antarctic cold for 60 days or more to protect his eggs, which he keeps on his feet, covered with a feathered flap. During this entire time he doesn't eat a thing. Most father penguins lose about 25 pounds while they wait for their babies to hatch. Afterward, they feed the chicks a special liquid from their throats. When the mother penguins return to care for the young, the fathers go to sea to eat and rest.

Investing facts, tip about hot stocks

The price of hot stocks like IPOs and tech stocks can rise and fall suddenly.

"In these fast markets when many investors want to trade at the same time and prices change quickly, delays can develop across the board. Executions and confirmations slow down, while reports of prices lag behind actual prices. In these markets, investors can suffer unexpected losses very quickly."

"To avoid buying or selling a stock at a price higher or lower than you wanted, you need to place a limit order rather than a market order. A limit order is an order to buy or sell a security at a specific price. "

How do you count cards in blackjack?

A blackjack card counter performs a simple calculation...over and over and over again. The goal is to bet more money when a deck is loaded with big cards 10,Jack, Queen,King, & Ace because the chances of a dealer busting increases. To figure out when the deck favors the player they do the following:
The card counter begins with zero. For every card that appears either they add 1, minus 1, or keep it the same.
If the card is a 2,3,4,5,6 you add 1. If the card is 10,j,q,k,ace you subtract 1. If it's a 7,8,9 the score remains the same.

So, a card counter will bet small while they keep count and if their tally reaches +5 or greater they increase their bet. This system relies on the law of large numbers which says while the bettor will lose or win money on a given day over time the bettor will have the advantage and thus be profitable long-term.

p.s. This is much easier said than done. This formula was introduced in Beat The Dealer in 1966 and the casinos are doing just fine. Good luck!

Easily attained substance found to reduce the risk of breast cancer!

In 2003, a North Carolina State University study of over 15,000 women found that women who performed the act of fellatio and swallowed semen on a regular basis - one to two times a week - reduced their risk of breast cancer by up to 40 percent. No benefit was found for those who did not participate regularly.

soothes a sore throat, and even manage depression!
