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.

Plectronocerida

We just learned about the White Spotted Octopus.

Another type of cephalopod is the Plectronocerida.

These are an extinct type of cephalopod like a nautilus that had a shell on it's back.
These cephalopods would crawl along the bottom of the water and eat food, almost like an underwater snail.

Maxillary Second Premolar

We just learned about the Maxillary - First Premolar.

The next teeth in the mouth are the Maxillary Second Premolars.

These also have two "cusps" on them like the First Premolars, so they are also bicuspids.
They are not as pointy as the First Premolars, so they are used more for grinding up food than tearing it up.

Just like the First Premolars, there are no baby or primary premolars.
The Second Premolars come up in the place where the baby molars were at when they fall out.

Epænetus, bishop of Carthage

We just learned about Crescens - bishop of Carchedon in Gaul, one of the seventy disciples.

Another of the seventy was Epænetus, bishop of Carthage.

Epænetus was called "my beloved" by Saint Paul in the book of Romans, and was said to be the first person to become a Christian in Asia.

He is believed by many to be the first Bishop of the city of either Carthage or Cartagena.

Da Yu ding

We just learned about the Yixian glazed pottery luohans.

Another ancient Chinese sculpture is the Da Yu ding.

A ding is used for storage or for special ceremonies and rituals.

This bronze ding sculpture was made around 1000 BC in Shaanxi China.
It has patterns and animal faces engraved on it, and on the inside of the ding is carved a speech from the Chinese King Kang of Zhou.

The speech talks about a few things:
Don't drink too much wine.
People need to support the king.
Everyone should try to be like the king's old grandfather Nang Gong.
All of the stuff the military owns and who is in charge of it.
The ding was made for his grandfather Nang Gong.

In the old days during wars a lot of times old sculptures like this would get destroyed, so it is hard to know what happened long ago because the history was erased.
This ding was hidden many times through the years so it was able to save the history of the past.
