Field of View

We just learned about the Central Retinal Vein.

Another part of the eyes is the Field of View.

When we are looking forward with our eyes, we see the things in front of us, but not behind us.
We also can only see part of what is up, down, left or right without moving our head to see it all.

Some of this is because parts of our head that get in the way like cheekbones or eyebrows.
Part of it is because our eyeballs are pointed forward.
Some animals like a rabbit or a deer have eyes on the sides of their heads, so they can see almost all the way in front and in back of their bodies.

The whole space of things that you can see with your eyes without moving them is called your Field of View, or FoV.

Weddel Sea

We just learned about the Filchner-Ronne Ice Shelf.

Another part of Antarctica is the Weddel Sea.

This is the water just to the East of the Antarctic Peninsula.
Some scientists believe this to be the clearest sea water in the whole world, and people have been able to see things down in the water over 250 feet deep.

The sea is about 1,200 miles across, and some sailors have said that it was the most dangerous sea on earth.
As people have taken their boats into this sea, sometimes the ice will flash freeze, and then melt again, and sometimes the ice will crush or tip over ships.

There are many animals who live in this sea, like the Weddell seal, killer whales, humpback whales, minke whales, leopard seals and crabeater seals.

There are also some penguins that live on the land in this area and swim in the sea.

King Charlemagne

We just learned about the Icons.

Another part of early Christianity is the rule of King Charlemagne, also known as Charles I or Charles the Great.

Around 770 AD a person named Charlemagne was the king over a lot of parts of Europe, like France, Germany and Italy.

There were a lot of people in those times fighting over who should be king or emperor, so Pope Leo III who was the head of the church in Rome told everyone to follow Charlemagne and that he should be the ruler over everyone else.

Charles loved reading, writing and music, so he helped make schools for people to learn and read the books of the Bible.
He also sent people to Rome to learn how to sing and they came back to the schools to teach people how to sing the Psalms of the Bible.

A lot of the writings of the Bible were in Latin or Greek, so Charles told people to make copies of them in other languages.
This made it so that everyone could read the Bible and learn about God and Jesus themselves.

Lion

We just learned about Cats.

The big cat known as the king of the jungle is the Lion.

Lions mostly live in Africa, but there are also some in the Middle East and Europe.

Lions are big cats that are part of the "Felidae" family.
The male lions have a big mane, and all lions have a hairy fluff of fur at the end of their tails.
They are usually 6 or 7 feet long, and they can weigh over 300 pounds!

Lions live together in a family that is called a "pride".
A pride is usually a few grown up males, then some females and little lion cubs.
When the little lion cubs are about 3 years old, the boy lions are sent off to live on their own, and the girl lions stay with the pride.
When boy lions are out by themselves, sometimes they will group together with a few other boy lions until they find a home where they join a new pride as a grown up male lion.

Lions can make a lot of sounds like purring and meowing, but they are best known for the lion's roar.
It is so loud that it can be heard up to 5 miles away.

There is one type of lion called a white lion, that has white or very light colored fur.
