This is a hard covering for the tooth just like the enamel that we learned about,
but it is covering the part of the tooth going down below the gums, called the root.
We just learned about Philologus - Bishop of Sinope, one of the seventy disciples.
t Caius - Bishop of Ephesus, one of the seventy disciples.
Another two of the seventy were Olympus and Rhodion.
Rhodion was also known as Herodion of Patras, and he was a relative of Paul and became a leader of the church in the town of Patras.
He had a very rough life and was beaten up by people who didn't like to hear what he said, and eventually he was killed along with his friend Olympas.
Another ancient Chinese work of art is the Eight Nested Relic Boxes.
Long ago in China a man called Buddha lived and many people followed him because of all the wise things he had to say.
He was so famous that when he died, they saved one of his finger bones and put it inside of a nicely carved box.
This box was put into another box and another.
There were a total of eight boxes, made of either gold, silver or jade, and wrapped in silk.
These boxes are in a museum now for people to come visit and see the box that people believe has the finger bone of Buddha inside.
Another part of navigating rockets is the science of Ballistics.
This is all about the forces that are moving the rocket around, and what happens to the rocket because of those forces.
Usually there are 4 forces on the rocket:
1. Thrust from the engine
2. Gravity
3. Drag - which is like the air blowing against the rocket
4. Lift - which is like air blowing with the rocket
Another type of cephalopod is the Opalescent Inshore Squid, also called Doryteuthis opalescens.
This is a very small squid, only growing to about 7 inches.
They live in the Pacific ocean by the eastern short of North America, all the way from Alaska to Mexico.
These squids are tiny but there are lots and lots of them.
The mother squids lay their eggs on the ocean floor, and there are so many that they cover acres and acres in the sand.
Because there are so many eggs there, a lot of ocean predators like starfish will go eat the eggs.
When the squids grow up, they are still very tiny but when they get together in groups there can be millions of them all in one place!
With so many of them swimming around, they are a big snack for other animals like sharks and seals.
