Meibomian Gland

We just learned about the Epicanthic Fold.

Another part of the eye is the Meibomian Gland.

Just inside the top and bottom eyelids are some small glands that help keep your eyes wet.
They let out a little bit of oily liquid called meibum that helps spread around the water tears that come out, help keep the tears from spilling over onto your face, and help keep the water from just evaporating.

If someone is having problems with their meibomian glands they can get really dry eyes.
The word "meibomian" was named after the person who discovered the glands, Heinrich Meibom.

Palmer Station

We just learned about the ANSMET Station.

Another research station in Antarctica is Palmer Station.

This station is right along the Antarctic Peninsula, and is actually on a small island named Amsler Island.
Because it is right on the water, this station spends most of its time studying the sea and the animals living in it near Antarctica.

There is a boat called the Laurence M. Gould that helps people travel from the station to South America.

The People's Crusade

We just learned a little about the The Crusades.

At the beginning of the Crusades, some of the church leaders were very upset because some people in other lands called Turks had come along and taken over other lands.
The Turks were not Christians, and many people said that the Turks were not nice to Christians in the lands they took over.
They also took over the holy places like Jerusalem.

Some of the church leaders called for people all over to attack anyone that wasn't a Christian, and even to kill them.
They called it a holy war, and told people that Jesus wanted this to happen and that if they died for this war Jesus would be happy, even though Jesus tried to teach people not to kill or hurt people.

One of the church leaders in Germany named Peter the Hermit gathered thousands of people and got them very angry at anyone that wasn't Christian.
These people were very poor and scared, and they followed him carrying shovels and pitchforks and not much else.
They were not well trained soldiers, but they were all told to go kill anyone that wasn't Christian, so they went through some parts of Germany and killed thousands of people.

Later they went up against some actual Turk soldiers, and almost all of the poor people were killed.

Because it was just normal people and not soldiers, this was called the People's Crusade.
It was a very sad time because these people didn't really know much of what was going on, they just needed someone to follow and they were poor and starving.
So they started the crusade, killed a lot of people, and then were killed themselves.

Patience and Fortitude - Edward Clark Potter

We just learned about the On the Prowl - Edward Kemeys.

Another famous American sculpture is Patience and Fortitude made by Edward Clark Potter in 1910.

Potter was born in Connecticut in 1857, and grew up in Massachusetts.
He started off going to college to be a minister, but then later studied to be an artist.

He worked with famous artist Daniel Chester French where he learned about animal studies, and when he was 53 he made the sculpture of two lions out of pink Tennessee marble that are outside the front of the New York public library.

He named the lions Leo Astor and Leo Lenox for the private libraries that are inside the library.
During the Great Depression, the mayor of New York said that the people there were showing great Patience and Fortitude, so they renamed the lions to Patience and Fortitude to honor the people that lived through the Depression.

Vacuum Pump

We just learned about the Steam Turbine.

Let's learn a little about how steam engines work.
First we need to learn a few other things that people discovered before they could make a steam vacuum.

One thing people discovered was the Vacuum Pump.

A long time ago people didn't understand a long time ago was how a vacuum worked.
Not like the vacuum cleaner that sucks dirt up from the floor, but a vacuum like a ball or a tube that is so empty that it has suction holding itself closed.

You can think about this like a plastic pop bottle that you suck air out of.
As soon as you let go, it will suck the air in and fill itself up again.

Back in 1654 people didn't understand this, so a man named Otto von Guericke came up with an experiment to show them.
He took two half circles made of metal, called the magdeburg hemispheres, and put them together like a closed ball.
Then he used a pump to suck out all of the air from inside, creating what is called a vacuum.

A vacuum is a space that has no air, or very little air.
Because he used a pump to do this, it was called a vacuum pump.

After that he challenged people to try and pull the half circles apart, but not even teams of horses could do it.
This understanding of how a vacuum works was one of the things that helped people invent steam engines.
