Transcript of Telescopes
Telescopes are used to look at the universe. It helps us understand the world above. We study stars, planets, and many other things.
The First Telescopes
No. Not magic like in "Harry Potter," but it is truly amazing how these work. Sorry, Ron.
A telescope basically is an instrument that collects electromagnetic radiation (i.e. visible light).
Types of Telescopes
I'm related to Isaac Newton's teacher, Isaac Barrow.
Where The Word Telescope comes from
From the Greek words
"to look or see";
HOW DARE YOU BECOME BORED! I AM ABSOULETLY DISGUSTED! I AM TRYING TO GIVE A PRESENTATION, AND IT'S NOT MY FAULT! IF YOU WHINE ONE MORE TIME, I WILL SEND YOU OUT OF THIS ROOM! Now let's continue.
What They're Used For
The first telescopes were first used in the Netherlands in 1608. In 1668 Isaac Newton made the first "real" reflecting telescope, today known as the Newtonian Reflector. It's magical, the way these telescopes worked.

You are a wizard. No, just kidding! This presentation is over. Sorry, for those who did not get the "Harry Potter" commentary. Thank you for watching. Bye!
Scientists can not improve the light gathering of a telescope, just by making it larger. Disturbances and nonuniformities in the atmosphere, affect the amount of light a telescope can gather. This is why you see telescopes atop mountains.
