Elevators

2012-01-23T04:48:00.000-08:00

Fact: The first elevator was built in 236 BC by the Greek scientist Archimedes, of Eureka! Fame. Early elevators were hoisted or wound around a drum, pulled by slaves or animals. The Coliseum in Rome in the first century BC had 24 elevators operated by over 200 slaves. In the middle ages, elevators based on winch system were popular in walled castles. Screw drive elevators were developed around 1800 and hydrolic elevators around the same time. The safety break was invented in 1853, which is when the elevator evolution started. Then in 1880 came electrical elevators. Soon after – elevator music. It’s purpose: to calm nervous elevator passengers and disguise the scary sounds of the elevator.

Fact: The first postage stamp was called the Penny Black and was created in England by Rowland Hill in 1840. It had a picture of Queen Victoria at the age of 15. Before the invention of the stamp postage was paid by recipient and price would be unpredictable and complicated. The Penny Black was produced for only a year, but so many copies of the stamp were printed that it is not considered a rare stamp today.

Breast pumps

Fact: The breast pump, a device to extract milk from a woman’s breasts, used when a woman is for some reason unable to breastfeed her baby, was first patented in 1854. A mechanical breast pump was invented in 1922. Breast pumps were used in hospitals, by mothers of preemies or women who for some reason could not breastfeed normally. Breast pumps became commercially available for non-hospital use in 1991, when Medela introduced an electric vacuum-operated breast pump. This was a revolution for working mothers, allowing them to continue feeding their children breast milk even after they had returned to work.

Stone age brain surgery

2012-01-16T16:05:00.000-08:00

Fact: Brain surgery dates back to the stone age and was performed in many different civilizations around the world. Cutting holes in the skulls was probably meant to relieve pressure and release evil spirits. The patients may have had problems such as epilepsy, headaches or depression. Evidence of the skull healing skulls indicates that the some patients survived for a while after surgery. This type of brain surgery was called trepanning, and has made a surprising comeback in recent years.

Fact: Four monkeys named Albert were launched into space in 1948 and 1949, but none of them survived. In 1948, Albert I was the first monkey astronaut. He flew on a V-2 Blossom rocket from White Sands Proving Ground in New Mexico. His flight only reached 39 miles, and Albert I suffocated. Albert II followed in his footsteps three days later, and reached an altitude of 83 miles, but died on impact after a parachute failure. Albert III flew in 1949, his rocket exploded soon after takeoff. A couple of months later Albert IV reached an altitude of 80 miles, but also died after a parachute failure.

Dimples

2012-01-13T02:37:00.000-08:00

Fact: Dimples are caused by a shortened muscle in the cheek. The short muscle pulls at the skin, especially when the person smiles, although sometimes dimples are visible without smiling. Dimples are inherited from one or both parents as a dominant trait and sometimes disappear or change as the person gets older and the muscle stretches out.

Dimples in the chin happen when the jawbone doesn't fuse perfectly together during the embryonic developent. They are also genetically determined.

Blood

2012-01-12T06:02:00.000-08:00

A fact: Apheresis is ancient Greek for "taking away". This word is used for a special kind of blood donation, where the blood of the donor is passed through a machine which removes certain components from the blood but returns the rest. In this way it is possible to collect plasma or platelets or red blood cells or white blood cells -- and even bone marrow cells for transplant. The donor usually does not need fluid replacement as most of the blood is returned to her body.
