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.

Asyncritus - bishop of Hyrcania

We just learned about the Rufus - bishop of Thebes, one of the seventy disciples

Another of the seventy was Asyncritus - bishop of Hyrcania.

Just like Rufus, Asyncritus was one of the people that Paul talked about when he wrote a letter to the people of Rome.

Asyncritus went on to the land of Hyrcania, which later became part of the country of Iran.

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.

Inertial Measurement Unit (IMU)

We just learned about the Airspeed Indicator.

Some of the tools we've talked about are things called Inertial Measurement Units or just IMU for short.

Inertia is the change in the rockets speed or direction, so the tools that we talked about like the gyroscope, magnetometer and accelerometer are all used to tell how the rocket is moving, so they are all IMUs.

IMUs all help measure things called Roll, Pitch and Yaw.

Roll is like when an airplane is still going forward in the air, but does a spin so it is flipped upside down, but still going forward.
Pitch is like when the airplane moves its nose to go down toward the ground or up toward the sky.
Yaw is like when the airplane isn't flying along and then turns left or right.

Different types of rockets use different IMUs depending on what kind of sensors they need, but they all are used to measure roll, pitch and yaw.

Southern Sand Octopus

We just learned about the Joubin's Squid.

Another cephalopod is the Southern Sand Octopus, also called octopus kaurna.

This octopus lives around Australia, and grows up to about 20 inches long, with very thin arms.

This octopus can not change colors like a lot of others can, so it stays hidden by burying itself in the sand.
It goes down by the bottom of the sea, and spits out a big jet of water down into the sand, then use its arms to quickly dive down into the hole it made.
