Hello friends! Welcome to a new Happy Learning video.
Today, we’re going to know why the stars, shine!
In summer, I love to watch the stars shine bright. They make me think and look back on many things…
Stars shine because they are gigantic burning hot gas spheres that release heat and light. They are so bright because there are atomic reactions inside them, that convert hydrogen into helium. Their temperature can reach 10.000 degrees centigrade. According to the colours they give off, astronomers know if they are hotter or cooler.
Our sun is a medium sized yellow star. Stars smaller than the sun are reddish and larger ones are blue.
Stars live for thousands of millions of years, but they always end up becoming extinguished.
When we look into the sky at night we can see hundreds and hundreds of stars. Some of them, either because they are very big or because they are closer to Earth, are very visible. Others, which are smaller or further away are tiny points that can hardly be seen.
At a glance from Earth, we can see about 2000 stars, but really, there are thousands and thousands of stars in the universe, but nobody knows exactly how many there are.
In the past, stars were very important for sailor’s orientation. Because of the Polar Star, the Ursa Major or Venus, sailors knew what directions to take and got to their destinations safe and sound. To see the stars better, they used devices such as the telescope.
The telescope is a gadget that works with light and is used to watch far away objects a lot clearer than by glance.
But… who was the inventor of the telescope?
The truth is we don’t know with certainty, but it was Galileo in 1609 who, using an invention by a Dutch man called Lippershey (Lipershy), built the first telescope that was used to look at the stars and because world famous.
Well, now we know why stars shine and the instrument so we can look at them. The truth is I love stars. What about you?

Finance and capital markets on Khan Academy: Hedge funds have absolutely nothing to do with shrubbery. Their name comes from the fact that early hedge funds (and some current ones) tried to "hedge" their exposure to the market (so they could, in theory, do well in an "up" or "down" market as long as they were good at picking the good companies). Today, hedge funds represent a huge class investment funds. They are far less regulated than, say, mutual funds. In exchange for this, they aren't allowed to market or take investments from "unsophisticated" investors. Some use their flexibility to mitigate risk, other use it to amplify it.
About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom.

Precalculus on Khan Academy: You may think that precalculus is simply the course you take before calculus. You would be right, of course, but that definition doesn't mean anything unless you have some knowledge of what calculus is. Let's keep it simple, shall we? Calculus is a conceptual framework which provides systematic techniques for solving problems. These problems are appropriately applicable to analytic geometry and algebra. Therefore....precalculus gives you the background for the mathematical concepts, problems, issues and techniques that appear in calculus, including trigonometry, functions, complex numbers, vectors, matrices, and others. There you have it ladies and gentlemen....an introduction to precalculus!

Finance and capital markets on Khan Academy: Interest is the basis of modern capital markets. Depending on whether you are lending or borrowing, it can be viewed as a return on an asset (lending) or the cost of capital (borrowing). This tutorial gives an introduction to this fundamental concept, including what it means to compound. It also gives a rule of thumb that might make it easy to do some rough interest calculations in your head.

Organic Chemistry on Khan Academy: Carbon can form covalent bonds with itself and other elements to create a mind-boggling array of structures. In organic chemistry, we will learn about the reactions chemists use to synthesize crazy carbon based structures, as well as the analytical methods to characterize them. We will also think about how those reactions are occurring on a molecular level with reaction mechanisms. Simply put, organic chemistry is like building with molecular Legos. Let's make some beautiful organic molecules!
