Attitude Control

We just learned about the Inertial Measurement Unit (IMU).

A lot of the sensors we've been talking about are all part of Attitude Control.

This means controlling where the rocket is and which way it is pointing.
The attitude of the rocket is where the rocket is moving, whether it's up, down, left, right, forward back.

Humboldt Squid

We just learned about the Southern Sand Octopus.

Another type of cephalopod is the Humboldt Squid, also known as the jumbo squid, jumbo flying squid, pota, or diablo rojo (red devil).

These squid can gro from 5 feet to 8 feet long, they live in the Pacific Ocean, and usually live around 1,000 feet under the water.
Just like some other cephalopods, they can change colors from white to red, which is where they get the nickname "red devil".
Sometimes these squids will talk to other nearby squids by flashing different colors!

This squid is a hunter, and when it is hunting other small fish it uses all of its 8 arms and 2 tentacles to reach out and grab the smaller fish or other animals it is hunting, then pull them into its mouth where it has a sharp beak used to cut up and eat the animals.
They are super fast hunters and can swim up to 15 miles per hour!

Some people have been attacked by this type of squid, but scientists think that only happens when the squid are feeding on other prey and are hunting.
When these squid get angry they have even attacked and broken deep sea cameras sent down to look at nature.

Dental Notation - Palmer

We just learned about Dental Notation - ISO.

Another type of Dental Notation is Palmer Notation.

This uses the same idea where the number starts at the front and goes backward, but it also uses a little L shaped or corner shaped symbol (┘└ ┐┌) to show which part of the mouth the tooth is in.

So if a dentist wants to talk about the 4th tooth in the upper right part of the mouth, they would use 4┘

Himeji Castle

We just learned about the Citadel of Aleppo.

Another famous castle is Himeji Castle in Japan, built around 1300 AD.

It is the largest castle in Japan, and because of its white color is sometimes called the "White Egret Castle" or "White Heron Castle" because it looks like a bird flying away.

The castle is over 5,000 feet long, and the area around the castle takes up over 500 acres.
Inside the castle area, the main building has 6 floors and a basement. It looks like 5 floors because from outside the top two look like the same floor.
The floors go from big at the bottom, over 5,000 square feet to small at the top, only about 1,000 square feet.

On the first floor there are over 300 tatami mats, which are special made floor spaces, and lots of weapons.
Each wall has weapon racks for holding spears and guns, and once had about 280 guns and 90 spears.

There are arrow slits through all the floors to shoot arrows at attackers, and the upper floors had places that people could come out and throw things at attackers below.
Outside there are three moats, and a big maze of pathways that go around and around the castle, up hills and in small spaces.
This was to make it so even if an army did attack, the castle would see them coming a long way out and be able to stop them with the moats.

Phoenix crown of Empress Xiaoduanxian

We just learned about the Shi Qiang Pan.

Another ancient Chinese work of art is the Phoenix crown of Empress Xiaoduanxian, made around 1500 AD in China.

In ancient times in China, queens brides and noble women would wear a special crown called Fengguan which means "phoenix crown".
The name comes from the phoenix decoration on the crown, made from feathers of the kingfisher bird.
There are also golden dragons, bearded pheasants, pearls and other gems.
Each crown was different and some would have more dragons or jewels based on how important the person was.

One of the fanciest phoenix crowns was from the Ming Empress Xiaoduanxian with 6 dragons, 3 phoenixes, 5,449 pearls, 71 rubies and 57 sapphires.
This kind of crown would weigh about five pounds.
