R-7 Rockets

We just learned about the PGM-11 Redstone.

Another type of rocket from history is the R-7 Rocket.
Sometimes it's called the R-7 Semyorka, because the Russian word for seven is "Семёрка" which sounds like Semyorka.

After World War II when the Russians brought German scientists to work for their country making missiles, they learned a lot about making missiles, and made the R-1, R-2, and R-5 missiles.
Then they sent the Germans home and started making their own missiles.

The Russians made a missile called the R-7, and it was the first "ICBM" missile which stands for "Intercontinental Ballistic Missile".
This means it could be launched from one continent like Europe or Asia, and fly all the way in the air to land on another continent like North America.

For the first time in history, someone could launch a missile from over 5,000 miles away to bomb another city.
Because this was such a scary thing, it pushed the scientists in the USA to try and make their own ICBMs to fight back if they were being bombed from across the Atlantic ocean.

The R-7 rocket was not just used for war, it was used for space exploration.
Sputnik was the first satellite to be launched into space to orbit the earth.
In 1957 the Russians used a type of R-7 rocket to launch it up into space.
This also pushed the other countries of the world like the USA to make rockets for space exploration.

Crystal Jelly

We just learned about the Upside Down Jellyfish.

Another type of jellyfish is the Crystal Jelly.

This type of jelly is mostly clear, with lines called radial lines in the bell part of its body called the bell that help it swim.

Around the outside of the bell are small tentacles that it uses to sting its prey, but the sting does not hurt humans.

It's mouth is hanging down in the middle, and this jelly eats very tiny things like plankton or barnacles.

They live mostly in the Pacific Ocean, off the coast of California.

Filiform Papillae

We just learned about the Taste Buds.

Another part of the tongue is the Filiform Papillae.

The lingual papillae that we learned about come in a few different shapes and sizes.
One of those is the filiform papillae, which are small and cone shaped, with small threads at the top.

These papillae do not have any taste buds, they are only used by the tongue for feeling, and to give the tongue a rough feeling.

The tongue has more filiform papillae than any other type of papillae.

Chillon Castle

We just learned about the Kilkenny Castle.

Another famous castle is the Chillon Castle, built in Veytaux Switzerland in 1005 AD.

It is built on a small island, right on the edge of Lake Geneva.

When it was first made, it was built to defend some of the valleys and roads in the area, but later on was used as a prison for some famous people.

The prince's castle in the Disney movie The Little Mermaid was made to look like this castle.

Antilegomena

We just learned about the Muratorian Fragment.

Another part of the early Christians working on the Bible is called Antilegomena.

When people were trying to collect all of the writings about Jesus and what happened to him and after him, some people disagreed on which were real letters and which ones were fake.

There was a lot of disagreement because long ago it was very hard to figure out which letters were real, so if people disagreed on a writing it was called Antilegomena.

It is a Greek word ἀντιλεγόμενα that means "spoken against".

Remember we learned about people deciding which books were "canon" meaning measured or accepted.
If a book or letter was Antilegomena, then it was usually not accepted as "canon" and would not be put into a Bible.

Ellora - Jain Caves

We just learned about the Ellora - Hindu Caves.

Another part of the Ellora area is the Ellora - Jain Caves.

The people who made the Jain believed in different things than the people who made the Hindu or Buddhist caves, but they were built right along side the Hindu caves at about the same time.

Just like the other two sets of caves, these areas have special sculptures of gods and goddesses that people worshipped, and also temples and special worship areas.
