Thor, dont worry, there will still be a lot of free content on Youtube. This is actually an opportunity for those who are making videos that they never wanted to give it for free in the first palce. Since video makers could not charge a fee on Youtube in the past, this is a significant move as it will bring a lot more creators and users together.

Tryn28, good question. We will try to answer the question of how calculus helps in everyday life in a article soon.
We have explained about how money is printed in an earlier article here.
Good point. While printed currency is often referred to as paper money (which is what the paragraph seeks to convey), to make the currency note long lasting, money is printed on a mixture which has a large component of rags or cloth.
A very good point and your Science teacher is right. The earth has witnessed periods of warming and cooling. The Ice age is an example of cooling of the earth. Cooling usually occurs because of the amount of sun light that enters the atmosphere. It could be blocked because of composition of the atmosphere, distance of the Earth from the sun, the ocean ciruclation and many other factors.
Thanks for bringing it to our attention. We have fixed it.
Tryn28, Thank you for pointing it out. We have fixed the spelling.
Rehannef, Good question. We looked it up for you from the NASA website and this is what they have to say on how asteroids get their names. Hopes this helps answer your question.
"How Asteroids Get Their Names
The International Astronomical Union's Committee on Small Body Nomenclature.is a little less strict when it comes to naming asteroids than other IAU naming committees. So out there orbiting the sun we have giant space rocks named for Mr. Spock (a cat named for the character of "Star Trek" fame), rock musician Frank Zappa, regular guys like Phil Davis, and more somber tributes such as the seven asteroids named for the crew of the Space Shuttle Columbia killed in 2003. Asteroids are also named for places and a variety of other things. Naming an asteroid for a pet was only allowed this one time.
Asteroids are also given a number, for example (99942) Apophis. The Harvard Smithsonian Center for Astrophysics keeps a fairly current list of asteroid names."
That is because North Korea did not let anybody into the country. They do allow people into the country even now. North Korean government is very secretive and it is difficult to get information about the roads and locations that is important for building a map.
Now however, citizens cartographers - map makers and people who know North Korea because they have either have lived or are now living in the country, have helped to add information to make the maps more informative.
Clara, we want to clarify, "Protestor" won the award in 2011.
