Another one of his famous inventions was called Leonardo's Robot.
Some time around 1495, Leonardo da Vinci came up with the idea to make a mechanical knight, that could move around.
He made some sketches on how to make it using pulleys and cables that were inside metal armor.
He showed it off to some people in Milan, and by pulling on cables he could make it stand, sit, and move its arms and head.
His robot has been lost, but some people have followed his designs and made copies of what they think his looked like long ago.
When we think of computers, some people think of the laptop they use at home, or the bigger computer they use at work.
Other people might think of the really big computers sitting alone in rooms at buildings doing gigantic amounts of work for hundreds, thousands or even millions of people.
There are other things that are computers that people don't really call computers, like tablets or iPads, cell phones, or video game systems.
All of these things have computers inside them that make them work.
These days even things like cars, airplanes, TVs, and even things like Washers and Dryers have tiny computers in them!
The first computers made were made over 50 years ago and filled up entire rooms with all of their parts.
Things have gotten so small now that a computer the size of your fingernail could do more than that whole room of computers did.
Another type of new world monkey is the Grey-Bellied Night Monkey.
Just like you would guess from their name, these monkeys stay up at night like an owl.
And just like an owl, they have really big eyes so they can try to see as much as they can in the dark.
These monkeys live only in some small parts of South America.
They only grow to be about 3 pounds, and they live in the trees eating fruit, vegetables, and small bugs.
Another part of the ear is the Semicircular Canals.
On the outside of the inner ear are three tubes that go out like circles and then come back to the ear.
These are part of the bony labryinth, and they are what help the body tell which direction the head is moving.
Inside these tubes is some liquid, and at the opening of the tubes are some very tiny hairs.
When you move your head around, the liquid bumps into the hairs, which send signals to the brain telling it that you are moving.
The three semicircular canal tubes go in three different directions so that they can tell whether you are tilting your head, moving up or down, or side to side.
Let's learn a little about the country of United Arab Emirates, also called Emirates or UAE!
This is a small country in the middle east, bordering Oman, Saudi Arabia, and the Persian Gulf.
It is about 32,000 square miles, and has about 10 million people living there.
People in UAE speak Arabic.
The flag for the United Arab Emirates is has a red stripe on the left, and then sideways stripes of green, white and red.
The red is for courage, bravery, hardiness, strength, and unity.
The white is for cleanliness, honesty, peace, and purity.
The green is for prosperity, hope, joy, love, and optimism.
The black is for winning battles and strength of mind.
To eat in UAE you might have maqluba, which is cooked meat, rice and vegetables, cooked in a pot and then flipped upside down when served.
The name maquluba means "upside down".
Visiting UAE you might go to Dubai to see the Burj Khalifa, the tallest building in the world at about half a mile high.

In Abu Dhabi there is some man made land in the shape of a palm tree, called the Palm Jumeirah.
Also in Abu Dhabi is the fastest roller coaster in the world at 149 miles per hour, at the Formula Rossa at the Ferrari World park.

Another famous Christmas song is We Three Kings, also called Three Kings of Orient, or The Quest of the Magi.
It was written in 1857 in New York by John Henry Hopkins Jr.
Hopkins was working as a church leader in Pennsylvania, and wrote the song for a Christmas pageant, based on the story in the book of Matthew chapter 2.
In the pageant he had each wise man sing one verse, and then all three would sing the final verse.
The Bible doesn't actually say there were three kings, it just says there were three gifts: gold, frankincense and myrrh.
It also doesn't say who the kings were, but later on in church history people think the wise men were named Gaspard, Melchior and Balthazar.
After the pageant it was just a song that his family and friends would sing together at Christmas time, but they all liked it so much he later decided to have it printed in a book of carols in 1916.
It then became famous all over the world, and was one of the first famous Christmas songs that was created in America.
Lyrics:
[Sung by All] We Three Kings of Orient are, Bearing gifts we traverse afar, Field and fountain, Moor and mountain, Following yonder Star.
CHORUS: O Star of Wonder, Star of Night, Star with Royal Beauty bright, Westward leading, Still proceeding, Guide us to Thy perfect Light.
[Sung by Gaspard] Born a King on Bethlehem plain, Gold I bring to crown Him again, King for ever, Ceasing never Over us all to reign.
[CHORUS]
[Sung by Melchior] Frankincense to offer have I, Incense owns a Deity nigh: Prayer and praising All men raising, Worship Him God on High.
[CHORUS]
[Sung by Balthazar] Myrrh is mine; its bitter perfume Breathes a life of gathering gloom; Sorrowing, sighing, Bleeding, dying, Sealed in the stone-cold tomb.
[CHORUS]
[Sung by All] Glorious now behold Him arise, King, and God, and Sacrifice; Heav’n sings Hallelujah: Hallelujah the earth replies.
[CHORUS]
