East Antarctica


We just started learning about Antarctica.

Antarctica is split up into two parts, Wast and East Antarctica.

The East part is the bigger part, and is sometimes just called Greater Antarctica.
It is closer to Africa and Australia, and the Indian Ocean.
The East and West parts of Antarctica are separated by a 2,000 mile long mountain range.

Anno Domini


We just learned about the Hagia Sophia ancient church.

Another part of early Christianity is Anno Domini.

When we talk about what year it is, we sometimes put the letters AD at the end, like 2019 AD.

The AD stands for "Anno Domini" which means "Year Of"
"Anno Domini" is just a short way to say "anno Domini nostri Jesu Christi" which means "year of our Jesus Christ".

A long time ago a man named Dionysius Exiguus was working on a new calendar to be different than the one that the old emperor Diocletian had used.
Diocletian was very bad for Christians and had many of them killed.

So Dionysius made a new calendar and said that the year was 525 AD.
By putting AD at the end, he was taking away the naming of the years from the bad Diocletian and giving it to Jesus.

In the new AD calendar, people believe that Jesus was born around 1 AD.
The time before that we call "BC" for "Before Christ".

In the old days before people used English they used "aCn" which was for "Ante Christum Natum" meaning "before Christ's birth".

Water Nymph and Bitterna - William Rush


We just learned about the Chacmool statue of the person laying down.

Let's learn about some sculpture from America long ago.

In the early 1800s there were not a lot of famous sculptures until William Rush came along.

His first famous sculpture was the Water Nymph and Bittern.

In the city of Philadelphia Pennsylvania, there was a river called the Schuylkill River that brought water into the city.
William Rush was asked to make a fountain for the city, so he made one of a woman and called her the water nymph, to be like a spirit that was living in the river that brought water to the city.
A bittern is a type of bird that lived around the river.

Russian - Do you speak Russian?


Remember that to say please or you're welcome in Russian, you say пожалуйста (pozhaluysta).

To ask if someone speaks Russian, you say:
Ты говоришь по-русски? (Ty govorish' po russki)
which sounds like tee goh-voh-dree-sh poh roo-skee - 文A
This is if you know the person pretty well.

If it is a grownup or teacher that you don't really know, you would say:
Вы говорите по русски (Vy govorishtay po russki)
which sounds like vee goh-voh-dree-tay poh roo-skee - 文A

To say yes you would say да (da) which sounds like dah - 文A

or to say no you would say нет (net) which sounds like nee-yet - 文A

Valve Port


We just learned about the valve Bonnet.

Another part of a valve is the Valve Port.

This is the part of the valve that lets water or gas in or out.
They can have as little as just two ports, but many valves have more.
Some valves even have up to 20 ports!

Simple two port valves are just open or closed.
Other valves with a lot of ports might have a few open and others closed depending on how it is set up.

Lappet


We just learned about the Nerve Net that is like a jellyfish's brain.

Another part of a jellyfish is the Lappet.

The circle shaped bell of a jellyfish is sometimes split up into parts by a small indent on the outside of the bell.
This little part where the bell dips toward the middle helps the jellyfish bell be able to flex and pull in and out so the jellyfish can swim.

Each of the parts of the outside of the bell between the indents is called a lappet.

Zonule of Zinn


We just learned about the Uvea.

Another part of the eye is the Zonule of Zinn.

This are the tiny little things like strings that go from the ciliary body to the lens.
Remember the lens is like the magnifying glass that changes shape so you can see far or close,
and the ciliary body is where the muscles are that help push and pull the lens to change it's shape.

It might sound like someone just wanted to come up with a funny name for a part of the body, but the word "zonule" means like tiny zone or tiny area, and the person who discovered this part of the body was named Johann Gottfried Zinn, so he named the area the Zonules of Zinn.

Sometimes it is also called Zinn's membrane, or the ciliary zonule, but Zonule of Zinn sounds the most fun.
