This is a quote. It can span multiple lines!

Here is a simple footnote,¹ and here is a longer one.²

Introduction to $E=mc²$

Note that $ and $$ should just render normally.

Einstein's mass-energy equivalence is one of the most famous equations in physics. It states:

where:

• $E$ is the energy of an object.
• $m$ is the mass of the object.
• $c$ is the speed of light in a vacuum (approximately $3\times {10}^8$ m/s).

In simple terms, this equation tells us that mass and energy are interchangeable. A small amount of mass can be converted into a large amount of energy, and vice versa.

Energy conversion in the Sun

For example, in the Sun, nuclear fusion reactions convert hydrogen into helium. In these reactions, a small amount of the mass of the hydrogen is converted into energy, according to the equation $E=m{c}^2$.

This is why the Sun has been able to produce enormous amounts of energy for billions of years.
