Tire Code


We just learned about the Tire Valve Stem.

Another part of a tire is the Tire Code.

If you look on the side of a car tire, you will see some letters and numbers printed on it.
These are there to help tell you what kind of tire you have, and also helpful things like how much air you should put into it.

Most tires use something called the "ISO Metric tire code" which has rules for what letters and numbers go in what order.

This code has these rules:

Use: One letter to tell how the tire will be used, like "P" for Passenger car, or T for a Temporary spare tire.
Width: Numbers for the width of the tire in millimiters.
/ in between the numbers
Height: Numbers for how tall the rubber part of the tire is. This is also called aspect ratio or profile.
Type of tire: One letter tells the type of tire, like R for a radial tire.
Rim width: The diameter of the metal rim that the tire is wrapped around.
Load: A code that tells how much weight the tire can take.
Speed ratimg: A code that tells how fast a tire can go.

So if a tire code says: P215/65R15 95H
That means it is a Passenger car, 215 milimeters wide, 65 millimeters profile height, Radial tire, 15 inch rims.
If you look up the 95H code, that means it can handle 1,520 pounds and go 130 miles per hour.

Eardrum


We just learned about the Vestibule of the Ear.

Another part of the ear is the Eardrum also called the tympanic membrane or myringa.

This is a thin piece of skin and tissue that works almost like a drum.
When sound comes into the ear, the eardrum vibrates.
There are nerves connected to the eardrum, so when it moves it sends signals to the brain telling it that the ear is hearing sounds.

The flag of East Timor has a red background, with a yellow triangle covered by a black triangle, and a white star.
The yellow is for the country's history, the black is for truth, the red is for freedom, and the star is for peace.

Silent Night


We just learned about the Lift High the Cross, by Joseph Mohr and Franz Xaver Gruber in 1818 in Austria.

One of the most famous Christmas songs is Silent Night.

The German name for this song is "Stille Nacht, heilige Nacht".
Mohr had written the song as a poem, and wanted Gruber to write the music to go with it for a Christmas church service.
A river had flooded the church and the organ didn't work anymore, so Gruber wrote music for the guitar.
It was later written in English in 1859 in New York City.

One time on a Christmas Eve in 1914 when British and German soldiers were at war, both sides stop fighting for one night and sang Silent Night in English or Stille Nacht in German, and went out to meet each other on the battlefield in peace.
It was called the Christmas Truce of 1914.

Codex Arundel


We just learned about Leonardo da Vinci's Codex Atlanticus.

Another one of Leonardo da Vinci's famous books of inventions is the Codex Arundel, written around 1500 AD.

While da Vinci was working on his art, he also took a lot of notes about how the world works.
He was learning about how weights and pulleys worked, how mirrors worked, and even had ideas about the sun and moon.

One of his ideas was to use a curved mirror to take sunlight and use the solar power it to heat up cauldrons.
His book Codex Atlanticus is 283 pages of his writings about how things work.
