Bellver Castle

We just learned about the Palace of Versailles.

Another famous castle is Bellver Castle, bult in 1311 on the Island of Majorca in Spain.

This was built long ago for King James II of Majorca, and it is a special castle because it is shaped like a circle!
The outside of the castle is a circle, the inside is a circle, and all of the towers are circles.
It is the only circular castle in Spain!

For a long time it was the home of the Kings of the land, but later was turned into a prison.
Now it is a museum and a place for tourists to come look at.

Tychicus - bishop of Colophonia

We just learned about Apollos - Bishop of Cæsarea, one of the seventy disciples.

The next two disciples listed were also with Cæsarea as being friends of Paul, and leaders of the churches.

Cephas - bishop of Iconium
Sosthenes - bishop of Colophonia

Another of the seventy was Tychicus - bishop of Colophonia.

He is mentioned a few different times in the Bible by Paul, where he was being sent to different churches to help teach the people there about Jesus.
Paul talks about Tychicus in the books of Acts, Ephesians, Colossians, Titus and Timothy, so he was a hard worker that Paul could send around to help people all over.

Kongōrikishi

We just learned about the Tamamushi Shrine.

Another type of Japanese sculptures is the Kongōrikishi (金剛力士), also called Niō (仁王).

These are two big mean looking sculptures with big muscles and weapons that were made as guardians for Buddhist temples.

One guard is making the "ah" sound and the other is making an "uhm" sound.
The ah is supposed to be like the first sound you make when you are born, and the uhm is the last sound you make before you die.
So the statues represent all life from birth to death.

Norwegian - Hello and Goodbye

We've now learned a whole year of Greek!
Wow!

Let's try another language now, how about Norwegian?
This is the language of the people of Norway, and it also is a lot like the languages of Danish and Swedish from the countries of Denmark and Sweden.
The vikings from long ago spoke a language called Old Norse, which later turned into Norwegian, so in a way it's the language of vikings!

Norwegian uses mostly the same alphabet as English, but it has some accents on the letters, like some of the other languages we've learned about.

It has three extra letters that are not in English: Æ, Ø, Å
These are vowels that make sounds like the a in apple, the u in cut or i in girl, or the o in lock or short.

Let's learn how to say hello and goodbye in Norwegian!

There are a few ways to say Hello.

Hi - Hei - Sounds like High
This is like saying Hi to your friends.

Hello - Hallo - Sounds like Hah-loh
This is like saying hello to a grownup, saying hello on the phone, or yelling hello to a friend from far away.

Bye - Ha det - Sounds like Hah-duh
This is just like saying bye to your friends.

Good Bye - Ha det brah - Sounds like Hah duh brah
Usually people just say hah det, but sometimes they say hah det brah, just like usually in English you say bye, but you might say goodbye sometimes.


(from: wikipedia - norwegian language)

Greek: Γειά σου, Χαίρετε, Αντίο

ASL: Hello and Goodbye

Italian: Ciao, arrivederci

German: Hallo, Auf Wiedersehen

Spanish: Hola! Adiós!

French: Bonjour! Au Revoir!

Bellifortis Rockets

We just learned about the Shock Diamond.

For the history of rocket science, the inventions were made either for war, or for fun like fireworks.

There was a book called Bellifortis written by a German scientist named Konrad Kyeser around 1400 AD that talks about rockets.
It says how rockets were being used for war but also for fun like fireworks.

Because there were no pictures back then, some people made drawings of the rockets, but no one knows for sure what they looked like.
In this book there was a drawing of the famous Alexander the Great holding a big rocket.

Konrad's book talks about rockets that were launched in the air, rockets that floated on the water, or rockets that were tied on a string.
These rockets probably all used the solid rocket fuel of gunpowder to launch them along.

Cephalopod - Funnel

We just learned about the Octopus Gills.

Another part of a cephalopod's body is the Funnel, also sometimes called a siphon.

When a cephalopod like a squid or octopus breathes in, they suck water into their mantle and then push it through their gills.

When they breathe out, they shoot the water out of a tube called a funnel.
They can even use that water shooting out like a little water jet and push their body along under water.
