Bonnet


We just learned about the Valve Body.

Another part of a valve is the Bonnet.

This is on top of the valve body, covering up the inside of it.
The bonnet can be taken off the top to open up the valve and fix it.

Nerve Net


We just learned about the Jellyfish Stomach.

Another part of a jellyfish's body is the Nerve Net.

In humans, our nervous system is our brain which is in charge of the rest of our body, and then our spinal cord and nerves that sends messages back and forth to the brain.

In most jellyfish, they have a nerve net which is kind of like the nerves we have all over, but without the spinal cord or a brain.

The nerves are all hooked together, and if a jellyfish senses something near by the nerve net can send messages all over it's body for the whole jellyfish to swim or try to pull in it's oral arms.
But it doesn't really have any thinking to it, it is just a very quick and simple reaction to a feeling.

It's kind of like if you touch something really hot, your hand very quickly pulls away without really thinking about it.
But if you were like a jellyfish, then your hand would touch something hot but your whole body would pull away, arms, legs and all!

Half Tower


We just learned about the Caltrop spikes in the ground.

Another type of fortification is a Half Tower.

This is a tower in a castle that is open in the back or on the sides.
It is usually open to the inside of the castle so that people can get in and out easily, but still be protected from the outside.

Pentarchy


We just learned about the Baptism of Clovis I.

Another part of early Christianity is the Pentarchy.

We've already learned that the head of the big churches were called Bishops, and that the Bishop of the church in Rome is called the Pope.

In the old days there were 5 churches in the Roman empire that were seen as the most important:

Rome - in what is now Italy
Constantinople - in what is now Turkey, and renamed Istanbul
Alexandria - in what is now Egypt
Antioch - in what is now Turkey, renamed Antakya
Jerusalem - in what is now Israel

There were other churches, but the leaders of these churches were put in charge, so if there as disagreement between all of the many churches around these leaders would decide what to do.

It was the start of the churches really getting organized and turning into a really big group instead of a bunch of small churches spread around that argued with each other.

Xicalcoliuhqui


We just learned about the San Martin Pajapan Monument I.

Another type of Mesoamerican art is Xicalcoliuhqui.

This word means "twisted gourd" and is something that is seen on a lot of art from the Mesoamerican areas from long ago.

It is made up of some small steps that are then connected to a spiral.
Ancient sculptures and paintings used this on buildings, clothing or other works of art.

Russian - Very good thanks, and you?

We just learned to say How are you? in Russian, Как дела? (kak dela)

and Very good thanks is Спасибо Хорошо (Spasibo khorosho)

To be polite you should also ask how the other person is doing.

In Russian sometimes you use different words if the person is a friend or a stranger, or a teacher or someone you are showing respect to.

If you are talking to a friend, you say:

And you? - А вы? (A vy?) - sounds like ah-vee - 文A

If you are talking to a stranger or a teacher you might say:

And you? - А ты? (A ty?) - sounds like ah-tee - 文A

russian language
