The Rocket into Planetary Space - Hermann Oberth

We just learned about the Le Prieur Rocket.

Another part of rocket history is the book The Rocket into Planetary Space by Hermann Oberth.

Oberth lived in Germany, and after reading the science fiction books by Jules Verne he loved thinking about rockets.
He became a scientist and wrote a book about launching rockets into space called "Die Rakete zu den Planetenräumen" which means "The Rocket into Planetary Space".

Later on he wrote another book called "Wege zur Raumschiffahrt" which means "Ways to Spaceflight".

In 1929 there was a movie called "Frau im Mond" which means "Woman in the Moon", and the director of the movie asked Oberth to make a fake rocket to use in the movie.

When it was made, the movie had the most real looking rocket ever made on film, with a multiple stage rocket, liquid fuel and other real parts of rocket science.

Oberth later went on to work for NASA to help make rockets for space flight.

Radula

We just learned about the Octopus - Three Hearts.

Another part of a cephalopod's body is the Radula.

We know that the octopus has a beak and that it uses the beak to bite it's food.
After the food gets into its mouth, there are tiny little teeth called the radula that help grind up the food.
It's almost like the octopus has a tongue with spikes on it that it rubs against the food to break it up into tiny pieces.

Masticatory Mucosa

We just learned about the Oral Mucosa.

Another part of the skin in the mouth is the Masticatory Mucosa.

This is the part of the wet mouth skin called gingiva that is on the roof of the mouth, and the top of the tongue.
The skin on these parts of the mouth is called keratinized stratified squamous epithelium.
That is a lot of big words that mean flattened skin with a lot of layers, that isn't loose and saggy.

It is different than other skin like underneath the tongue that is very loose.

Castillo de Coca

We just learned about the Alhambra.

Another famous castle is Castillo de Coca, built in 1493 in Coca, Segovia, Spain.

This castle is special because it has a type of brick work called Mudejar.

There were people living in Spain that were from another country with very different styles.
Mudejar means "allowed to stay", and it was used for people that were from another country but were allowed to stay in Spain.
While they stayed there, some of the types of castles they made back home were made in Spain just like the Castillo de Coca.

The castle has a moat and a keep, and an outside wall around the main castle.
Inside the central keep is a 82 foot tower, and walkways around the top of the walls with all sorts of defenses for the people inside to use if they were being attacked from below.

Against Heresies - Irenaeus

We just learned about the Didache - The Teaching of the Twelve Apostles.

Another part of early Christian history is the book Against Heresies, by Irenaeus.

During the early time of Christianity when people disagreed about what they should believe, there was a group of people called the Gnostics.
They believed that Christ and Jesus were two separate beings.
Like Jesus was a physical body, and Christ was a spirit that lived in him.

The bishop of France named Irenaeus was very upset about this, and decided to write a book saying why they were wrong.

His book was written some time around 180 AD, and many church leaders used that letter to tell people that they believed Gnosticism was not true.

Mokujiki Shonin

We just learned about the Wooden Budda by Enkū.

Another famous Japanese sculpture is the Mokujiki Shonin.

Just like Enkū that we learned about, Mokujiki Shonin was a monk who traveled around and talked to people.
Once when he was visiting a village, he saw a sculpture of Buddha made by Enkū, and decided to become a sculptor just like him.

His sculptures always seemed very free and rough, close to nature and happy.
