For me, I don't have any interesting things related to physics to tell or should I say I do not know whether the things I experienced was actually related to physics. I simply learned them for now and I'm hoping I will discover amazing things from now on.
Did you guys know that the Aurora Borealis which is one of our most beautiful phenomena in the world is related to physics? If you guys don't have any idea for what I'm talking about, I'm going to provide a picture. It is also known as the Northern Lights. It has always amazed people since it was first discovered as it was so unique.
This phenomenon occurred when the sun gives off high energy charged particles called ions that travel into space at the speed of 300 to 1200 kilometres per second which is really fast. A cloud of the charged particles is called plasma. The stream of plasma that came from the sun is called the solar wind. As the solar wind interacts with the edge of the earth's magnetic field, some of the particles are trapped thus following the lines of the magnetic force down into the ionosphere. The ionosphere is the section of earth's atmosphere that extends from about 60 to 600 kilometres above the earth's surface. When the particles collide with the gases in the ionosphere, they started to glow producing the auroras light that we know as Aurora Borealis.
