V-2 Rocket


We just learned about the Bell X-1.

Another part of rocket history is the V-2 Rocket.

During World War II when everyone was making rockets for war, the Germans made a rocket called the V-2.
It came from the German words "Vergeltungswaffe 2" meaning "Retribution Weapon 2".

It was the world's first missile that used a guidance system to make sure it hit the target.
The rocket used ethanol and liquid oxygen for its propellant, and launched itself into the air for 65 seconds.
After that it would start falling towards its target, and it used gyroscopes, accelerometers and tail fins to guide its path as it fell toward the target.

It was also the first man made object to go into outer space on June 20, 1944.

After the war, Great Britain, the USA, the Russians all used these rockets to help learn how to make rockets to launch into space.

Crown Jellyfish


We just learned about the Purple Striped Jelly.

Another type of jellyfish is the Crown Jellyfish, also sometimes called the cauliflower jellyfish or cephea.

The rounded top of a jellyfish's body is called the bell.
On top of this jellyfish's bell is what looks like a cauliflower crown, so that is where they get their nickname.

The bell of this jelly is a bluish purple colored skirt, that they use to swim along.
On the bottom of the jelly are large orange brown mouth arms that it uses to eat with, and a bunch of very small tentacles that it uses to sting its prey so it can eat it.

Conwy Castle


We just learned about the Château de Chambord.

Another ancient castle is Conwy Castle in Wales, built around 1283.

This castle was used as by king Richard II for a while during a war, and survived many battles.

It is built right up against the shore of the River Conwy, and there was an old secret entrance that went down to the water where people could sneak in and out or get food and other supplies.

It has eight large towers, two main areas called the inner and outer wards, and two small areas for protection called barbicans.

A barbican is like a wall or gateway with small towers that was used to help defend the castle.

Tetramorph


We just learned about Biblical Canon.

Another part of early Christianity is the Tetramorph.
This word comes from the Greek words "tetra" which means four, and "morph" which means shape.

When people started to put together the writings of the apostles, there were the writings we call the Gospel, that told about Jesus life.

The four books of the Gospel we know are Matthew, Mark, Luke and John.

In the Old Testament in the book of Ezekiel, he writes about a vision God gave him showing some creatures that had 4 different faces.
The face of a human, a lion, an ox and an eagle.

Some people believe that those four faces are for the four gospels, and so sometimes in art the four writers of the gospel are shown either sitting next to those animals, or sometimes even with animal heads on human bodies.
Matthew is shown as the human, Mark as the lion, Luke as the Ox, and John as the Eagle.

This way of showing the four writers of the gospel was called the Tetramorph, and it also became a way to talk about the four gospels.

Ellora - Buddhist Caves


We just learned about the Sanchi Capital of Ashoka.

Another part of Indian sculpture is the Ellora - Buddhist Caves, in Maharashtra India.

These caves have artwork from thousands of years ago, and there are over 100 caves, with sculptures and artwork for different people with different beliefs.

There are 12 caves called the Buddhist caves, because they all have artwork about Buddha.
They were carved around 600 or 700 AD.

Eleven of these caves are called "viharas", which are monastaries with prayer halls.
These viharas had places for people to live, sleep, cook food and pray.
Cave number 11 was three stories high and had many rooms.

Inside some of the rooms were sculptures of Buddha or other statues that people would worship.
