Dental Notation - Universal Numbering System

We just learned about Hypodontia.

When a dentist wants to look at your teeth, they give all your teeth a number so they can talk about which ones are healthy or have cavities.

This is called Dental Notation.

There are a few different ways that people number the teeth.
One way is called the Universal Numbering System

Sometimes a dentist will start with the upper right back adult or permanent tooth as #1 and then go 2,3,4,5,6,7,8 to the top middle, and 9,10,11,12,1314,15,16 to the top back left tooth.
Then next is the lower back left tooth at #17, and then toward the front 18,19,20,21,22,23,24.
From the front left around to the front right, 25,26,27,28,29,30,31,32.

Those are for the adult teeth.
If it's a primary or baby tooth, they use ABCDE from top right to top middle, and FGHIJ from top middle to top left.
KLMNO from bottom left to bottom middle, and PQRST from bottom middle to bottom right.

Prague Castle

We just learned about Kronborg Castle.

Another ancient castle is Prague Castle, built around 870 AD in Prague.

This is the largest ancient castle in the world, taking up about 750,000 square feet.
It was the home for the kings of the land of Bohemia, the Roman emperors, and presidents of the country of Czechoslovakia.
The Bohemian crown jewels are in this castle inside a hidden room.

In 1618, a war started because of something called "defenestration" which means throwing someone out the window.
Some angry mobs came around and tried to throw some rulers out of a window 70 feet high, but the people lived, and other people fought back and started a war.

The castle complex is made up of many buildings, like 4 churches, 4 palaces, 9 gardens, several schools and houses, fountains, statues and even a vineyard for growing grapes to be made into wine.

Agabus the prophet

We just learned about the Aristobulus - bishop of Britain, one of the seventy disciples.

Some more people on the list of seventy that we don't know much about are:.

Narcissus, bishop of Athens
Phygellus, bishop of Tarsus.

Another of the seventy we know a little more about is Agabus the prophet.

Agabus was talked about in the Bible as one of the apostles who was around when the Holy Spirit came down to the apostles.
He went to Jerusalem, and helped tell people about a really bad famine that was coming, where there would be no food.

Qin Bronze Chariot

We just learned about the ancient Chinese sculpture Gouji Zibai Pan.

Another ancient Chinese sculpture is the Qin Bronze Chariot, made some time around 200 BC.

This sculpture is of a driver with two seats in a chariot, with a large bronze umbrella.
The chariot is being pulled by four bronze horses, about half the size of a real horse.

It was found broken into many pieces, and it took five years to put the whole sculpture back together.

Spacecraft Magnetometer

We just learned about the Gyroscope.

Another tool used for navigation and guidance is a Spacecraft Magnetometer.

This uses a magnet that is wrapped in metal coils, with electricity running through the metal coils.
If there are other magnetic forces around, these electric coils will give off fields that can tell the rocket which way to go.

Stumpy spined cuttlefish

We just learned about the Ammonoidea.

Another type of cephalopod is the Stumpy spined cuttlefish, also called the dwarf cuttlefish, or sepia bandensis.

This is a cuttlefish that is very small. It's about 3 inches long, and doesn't even weigh one pound!
They are light brown or yellow, with white spots on their heads, white stripes on their body, and blue spots on their fins.

These cuttlefish live in shallow waters near the country of Indonesia, usually by coral reefs.
One interesting thing about these cuttlefish is that they don't swim!
They use their arms and flaps on their body to walk along the floor of the sea.
