The Seven Seas

This list of the seven seas is believed by many to be the original seven seas as defined by the sailors of ancient and Medieval Europe. The majority of these seven seas are located around the Mediterranean sea, very close to home for these sailors. Heard of Simbad and the seven seas?

The Mediterranean Sea
This sea is attached to the Atlantic Ocean and many early civilizations developed around it, including Egypt, Greece, and Rome , and it has been called 'the cradle of civilization' because of this.

The Adriatic Sea 
This sea separates the Italian peninsula from the Balkan peninsula. It is part of the Mediterranean sea.

The Black Sea 

This sea is an inland sea between Europe and Asia. It is also connected to the Mediterranean sea.

The Red Sea

This sea is a narrow strip of water extending south from North east Egypt and it connects to the gulf of Aden and the Arabian sea. It is connected today to the Mediterranean sea via the Suez canal and is one of the most heavily traveled water ways in the world.

The Arabian Sea

This sea is the North western part of the Indian ocean between India and the Arabian peninsula (Saudi Arabia). Historically, it was a very important trade route between India and the west and the remains such today

The Persian Gulf

This sea is a part of the Indian Ocean, located between Iran and the Arabian peninsula. There has been dispute as to what its actual name is, so it is also sometimes known as the Arabian Gulf, The Gulf, or the Gulf of Iran, but none of those name are recognized internationally.

The Caspian Sea

This Sea is located on the Western edge of Asia and the Eastern edge of Europe and It's the largest lake on planet. It is called a sea because it contains salt water.

Facts About Your Heart.

Here are seven great things you probably never knew about your heart.

Many people think the heart is on the left side of their chest, but the heart is actually located almost in the center of the chest, between the lungs. It's tipped slightly so that a part of it sticks out and taps against the left side of the chest , which is what makes it seem as though it is located there.

Give a tennis ball a good, hard squeeze you're using about the same amount of force your heart uses to pump blood out to the body. Even at rest, the muscles of the heart work hard - twice as hard as the leg muscles of a person sprinting.

The aorta, the largest artery in the body, is almost the diameter of a garden hose. Capillaries, on the other hand are so small that it takes ten of them to equal the thickness of a human hair.

The heart pumps about 1 million barrels of blood during an average lifetime- that's enough to fill more than 3 super tankers.

A woman's heart typically beats faster than a man's. The heart of an average man beats approximately 70 times a minute, whereas the woman has a heart rate of 78 beats per minute.

Because the heart has its own electrical impulse , it can continue to beat even when separated from the body , as long as it has an adequate supply of oxygen.

Seven Great Women Inventors

We are bombarded by so much impressive new technology that it's easy to forget that many of the simple items we use everyday were once considered breakthroughs. It's probably not suprising that women had a hand in creating many of these ubiquitous items. Although the times in which these ideas were conceived prevented many of the inventors from reaping full benefits of their genius,the tools and products we rely on today may not have been possible without their pioneering work.

MARGARET KNIGHT
Margaret Knight, remembered as 'the female Edison -received some 26 patents for such diverse items as a window frame and sash, machinery for cutting shoe soles, and improvement to internal combustion engines. Her most significant patent was for machinery that would automatically fold and glue paper bags to create square bottoms, an invention which dramatically changed shopping habits.

SARAH BREEDLOVE WALKER
Sarah Walker, the daughter of former slaves, was orphaned at seven and widowed by 20. Madame Walker is credited with inventing hair lotions, creams, and improved hair styling hot comb. But her greatest achievement may be the development of the walker system, which included a broad offering of cosmetics, licensed walker agents and walker schools, which offered meaningful employment and personal growth to thousands of walker agents, Sarah walker was the first American woman self made millionaire.

MARY ANDERSON
During a trip to New York city Mary Anderson noticed that street car drivers had to open the windows of their cars when it rained in order to see, as a solution she invented as a swinging arm device with a rubber blade that was operated by the driver from within the vehicle via a lever. Her invention could clean snow, rain, or sleet from a windshield and it became standard equipment on all american cars by 1916. Mary Anderson patented the windshield wiper in 1905.

BETTE NESMITH

Bette Nesmith, an American typist and commercial artist, discovered something she couldn't live without: liquid paper. She used it secretly to correct mistakes she and co-workers made on the job, but eventually started her own company and began selling the products as 'liquid paper'. The company was sold to the Gillette corporation in 1979 for $47.5 million.

GERTRUDE B. ELION

Gertrude Elion, 1988 Nobel laureate in Medicine, and scientist emeritus with Burroughs Welcome company, is credited with the synthesis of two of the first successful drugs for leukemia, as well as imuron, an agent to prevent the rejection of kidney transplants, and zovirax, the first selective antiviral agent against herpes virus infections. Researchers who discovered AZT, a breakthrough treatment for AIDS , used Elion's protocols. Elion was included into the National Inventors Hall of fame in 1991, the first woman inductee.

STEPHANIE KWOLEK

Stephanie kwolek, one of dupont's leading chemists, discovered the 'miracle fiber' Kevlar, which has five times the strenght of steel by weight -uses for kevlar are seemingly endless, including ropes and cables for oil drilling rigs, boat sails, etc. Many Vietnam veterans and police officers are alive today because of protection provided by bullet-proof vests made from Kevlar. Kwolek was inducted into the National Inventors hall of fame in 1995.

JOSEPHINE COCHRAN

When Josephine Cochran ordered her servants aside and began washing her own dishes, she had a revelation : washing dishes was true drudgery. This realization is what led Cochran to invent the first practical dishwasher that used water pressure for cleaning. She succeeded in creating a working model, and patented it in 1886. The dishwasher included a larger model, and the model could clean 240 dishes in two minutes, as a result, it became popular with hotels and restaurants.
