Tensor Tympani

We just learned about the Stapedius Muscle.

Another muscle in the ear is the Tensor Tympani.

This muscle is in the middle ear and is connected to the malleus or hammer bone.
When you are chewing your food that would be really loud in your ears since the ear is right by the mouth.
But the tensor tympani muscle tightens up when you are chewing and that helps to block the sounds that your mouth makes so it is not so loud when you eat.

Good King Wenceslas

We just learned about the Christmas carol Angels We Have Heard on High.

Another famous Christmas carol is Good King Wenceslas.

This song is was written about an old story of a king and his helper who went out during cold winter snowy weather and help take care of poor people.
Around 930 AD, Wenceslas was the Duke of Bohemia which is now called the Czech Republic, and the story says he did this during the Feast of Stephen, which is on December 26th, and is meant to honor the apostle Stephen from the Bible.

The words for the song wer writen in 1853 by John Mason Neale from England, and the music came from another old song from 1582 in Finland called "Tempus adest floridum" which means "Eastertime has come".

Lyrics:
Good King Wenceslas looked out, on the Feast of Stephen,
When the snow lay round about, deep and crisp and even;
Brightly shone the moon that night, tho’ the frost was cruel,
When a poor man came in sight, gath’ring winter fuel.

“Hither, page, and stand by me, if thou know’st it, telling,
Yonder peasant, who is he? Where and what his dwelling?”
“Sire, he lives a good league hence, underneath the mountain;
Right against the forest fence, by Saint Agnes’ fountain.”

“Bring me flesh, and bring me wine, bring me pine logs hither:
Thou and I will see him dine, when we bear them thither.”
Page and monarch, forth they went, forth they went together;
Through the rude wind’s wild lament and the bitter weather.

“Sire, the night is darker now, and the wind blows stronger;
Fails my heart, I know not how; I can go no longer.”
“Mark my footsteps, good my page. Tread thou in them boldly
Thou shalt find the winter’s rage freeze thy blood less coldly.”

In his master’s steps he trod, where the snow lay dinted;
Heat was in the very sod which the saint had printed.
Therefore, Christian men, be sure, wealth or rank possessing,
Ye who now will bless the poor, shall yourselves find blessing.

Another type of primate is the Greater Dwarf Lemur, or cheirogaleus major.

Lemurs are part of a whole different group of primates, not like chimpanzees, apes or monkeys.
There are a lot of different types of lemurs, and they all come from the island of Madagascar.

The greater dwarf lemur can grow to about 10 inches long, and weigh about 1 pound.
Their fur is gre or red, with dark circles around their eyes.

They live up in the trees eating mostly fruits, flowers and nectar, and sometimes bugs.
Unlike a lot of other monkeys that leap from tree to tree, these primates are not good leapers and they mostly walk along on all fours.
These primates are also quieter than most others and will just someetimes make quiet calls to other greater dwarf lemurs.

The chorus of this song is "Gloria in excelsis Deo", and it is Latin for "Glory to God in the Highest" which comes from the Gospel of Luke in the Bible.

Lyrics:
Angels we have heard on high Sweetly singing o'er the plains
And the mountains in reply Echoing their joyous strains
Gloria in excelsis Deo! Gloria in excelsis Deo!

Shepherds, why this jubilee? Why your joyous strains prolong?
What the gladsome tidings be? Which inspire your heavenly songs?
Gloria in excelsis Deo! Gloria in excelsis Deo!

Come to Bethlehem and see Him whose birth the angels sing;
Come, adore on bended knee, Christ the Lord, the newborn King.
Gloria in excelsis Deo! Gloria in excelsis Deo!

Tarsiers have really big eyes, but they can't move their eyes around to look left or right, they have to move their head around to look.
Because of this, they can turn their heads around almost all the way and look behind them.
With their big eyes, they like to stay up at night and hunt for small bugs to eat.

They looked up and saw a star Shining in the East beyond them far
And to the earth it gave great light And so it continued both day and night.
Noel, Noel, Noel, Noel Born is the King of Israel!

And by the light of that same star Three Wise men came from country far
To seek for a King was their intent And to follow the star wherever it went.
Noel, Noel, Noel, Noel Born is the King of Israel!

This star drew nigh to the northwest O'er Bethlehem it took its rest
And there it did both Pause and stay Right o'er the place where Jesus lay.
Noel, Noel, Noel, Noel Born is the King of Israel!

Then entered in those Wise men three Full reverently upon their knee
And offered there in His presence Their gold and myrrh and frankincense.
Noel, Noel, Noel, Noel Born is the King of Israel!

Then let us all with one accord Sing praises to our heavenly Lord
That hath made Heaven and earth of nought And with his blood mankind has bought.

It was called a mouse, because it looked like a little mouse with a tail, but lots of computer mice these days don't even have wires.

When you move the computer mouse around, there is a picture on the monitor usually shaped like an arrow called a cursor.
Computer mice usually have 2 buttons, and when you press the button it's called clicking.
If your mouse cursor is pointing at something like a button and you click the left button it will press the button on the screen.
The right button is usually to give you choices for things, like if you want to copy or paste some text just like you would from the keyboard.

God Rest Ye Merry Gentlemen

We just learned about the Christmas song Joy to the World.

Another famous Christmas song is God Rest Ye Merry Gentlemen, also called Tidings of Comfort and Joy.

This song is very old, and has been found in song books going back before the year 1700 AD.
No one is really sure who wrote the song, but it became very famous after Charles Dickens had it as part of his book A Christmas Carol, where Ebeneezer Scrooge hears carolers singing this and chases them away.

One interesting thing about this song is that the old meaning of "God rest ye merry gentlemen" really meant something like "May God give rest and happiness to the gentlemen", but now these days we think of it more like "May God give rest to the happy gentlemen".

The difference all came when someone moved the comma in the sentence:
Old: God Rest Ye Merry, Gentlemen
New: God Rest Ye, Merry Gentlemen

Computer Keyboard - Special Keys

We just learned about the Computer Keyboard - Function Keys.

Another bunch of keys on the computer keyboard are the Special Keys.

We know the keyboard has all of the letters of the alphabet on it, but it also has some special keys that aren't used to type letters or numbers.
These special keys can do things like delete letters, move around the place on the monitor where you are typing, scroll up and down, or even do special things like save or quit.
A lot of the special keys have to do with moving the "cursor".
The cursor is the place on the screen that you are currently working at.
Sometimes it looks like this: | and sometimes it is just something highlighted a different color.
You move around your cursor to type words in different places, or to choose different parts of a program on the screen.

On most keyboards these are the special keys and what they can do:

Esc - This key can either leave or stop a program.
Tab - Can either put a big [   ] space in between a sentence, or it can be used to make different choices in other programs or switch programs.
Backspace - This will get rid of one letter to the left of where you were typing.
Insert - This can turn on "type over" meaning typing new letters will take the place of old ones.
Home - This moves the cursor to the beginning of a text line.
Page Up/Down - This scrolls the window up or down.
Delete - This will get rid of one letter to the right of where you were typing, or it can be used to get rid of files or emails or other things the cursor is selecting.
Shift - If you hold down Shift and type, the letters will be ALL CAPITALS.
Caps Lock - This is like using Shift, but you don't have to hold it down for the letters to BE ALL CAPITALS.
Print Screen - This can take a screenshot of what your monitor looks like that you can save in another program.
Scroll Lock - Some programs use this to change the way they scroll up or down.
Pause/Break - Some programs use this to pause.
Num Lock - If your computer has a number pad, turning this on uses numbers, off uses whatever special options are there.
Ctrl - This is a key used with others to do special tasks.
These special tasks work with most programs: Ctrl+A = Select all, Ctrl+B = bold, Ctrl+C = Copy, Ctrl+F = Find, Ctrl+I = italics Ctrl+N = New, Ctrl+O = Open, Ctrl+P = Print, Ctrl+S = Save, Ctrl+U = underline, Ctrl+V = Paste, Ctrl+X = Cut, Ctrl+Z = Undo.
Alt - Use the menus at the top of the program, like Alt+F usually opens the File menu.
[Windows] - The key that looks like 4 boxes is the windows key that opens the menu for programs.
Arrows - Arrow keys help move the cursor around on the page.
