Maxillary First Molar

We just learned about the Maxillary Second Premolar.

Another tooth in the human mouth is the Maxillary First Molar.

These teeth have cusps or pointy parts on them like the bicuspids, but they have four points instead of the two of a bicuspid.
There are two cusps on the cheek side, and two on the tongue side.
Sometimes people have a fifth cusp called the Cusp of Carabelli.

Molars are used for grinding up food that is in the mouth.

There are primary or baby teeth molars, but those are replaced by premolars.
The adult molars show up further back in the jaw after the mouth gets big enough to have space for them.

Malbork Castle

We just learned about Edinburgh Castle.

Another famous castle is Malbork Castle, built around 1300 AD in Malbork, Poland.

This is the largest castle in the world, with a land area of over 52 acres!

Long ago the castle was one of the palaces where the royal family would stay.
Because of all the wars Poland was involved in, the castle has been owned by a few different countries.

During World War II there was a lot of damage on the castle.
After Poland took the castle back they have fixed it up, and it is now a museum for people to come visit.

Andronicus - bishop of Pannonia

We just learned about Epænetus, bishop of Carthage and one of the seventy disciples.

Another of the seventy was Andronicus - bishop of Pannonia.

When Paul was writing a letter to the people in Rome, one of the parts of the letter was written to Andronicus, who he said was in prison with him, and was a Christian before Paul had a vision of Jesus and believed.

Paul also mentions Junia, who people believe was the wife of Andronicus.
Andronicus and Julia went on to the place called Pannonia to spread the word of God.
Pannonia was a part of the Roman empire long ago, but now it is split up into parts of a bunch of different countries like Hungary, Austria, Croatia, Serbia, Slovenia, Slovakia, Bosnia and Herzegovina.

Da Ke ding

We just learned about the Da Yu Ding.

Another famous Chinese sculpture is the Da Ke ding, made around 1000 BC in Shaanxi China.

Just like the Da Yu ding, this is a large sculpted bowl on a tripod, used to hold things usually for special ceremonies.

Along with the Da Yu ding and another ding, it is one of the most sacred historical treasures in China.

During the many wars through the years in China, enemies would come through towns and try to destroy all of the special sculptures and take the treasures of people.

The Pan family was the owner of the Da Ke ding, and they knew people would try to destroy it so they buried it underground to hide it.
Armies came into town and tried to dig around and find it, but they never did, so it is one of the few pieces of history telling the story of what happened long ago.

It is about 36 inches tall and weighs over 400 pounds.
It has special patterns and dragons carved into it, and inside are 290 letters inscribed telling the story of Ke, the ruler of the Western Zhou dynasty.

GNC - Guidance, navigation and control

We just learned about Gimbaled Thrust.

After a rocket is launched, it needs to be guided to make sure that it goes to the right place, whether that's outer space or just up into the atmosphere.

This is called Guidance, navigation and control, sometimes shortened to just GNC.

GNC is the science of how to control a rocket after it's been launched up into the air.
