**Introduction**

Well well well… we’re at one of the best topics in Astrophysics in my opinion. Stars are absolutely fascinating, they look small specks in the sky, smaller than a thumbtack… yet they’re huge balls of plasma, often times having a radius of thousands of kilometers, yet our understanding of stars is very minute, we have a long way to go so buckle up.(Also I’m very sorry for not posting in quite a while, I’ve been extremely busy with schoolwork.) Stars are so cool that the logo of Project Bluestar is a Star!!!

Coordinates is something we learn in middle school that sticks with us for quite a lot of time but what exactly are their applications? What use do we get from plotting points on an x-y coordinate system and how exactly do they help us? We’re going to find that out today

I think the universe is pure geometry — basically, a beautiful shape twisting around and dancing over space-time.

**x-y** **coordinate systems**

While it may seem fundamental, we might as well cover the basics of an x-y coordinate system just for revision. …

Yes finally, we’re going to start with something Astrophysics related! Now before we delve in, I’m legally obligated to tell you that this is a point of no return.

During the course of this article, you will be exposed to the prettiest of pictures and the most interesting facts. In fact your mind is probably not going to comprehend what will be covered because it’s just — mind blowing. Let’s go!

“The size and age of the Cosmos are beyond ordinary human understanding. Lost somewhere between immensity and eternity is our tiny planetary home.”

**Introduction**

I suppose this is kind of an Astrophysics topic? Well, I would say it is. Now distances seem kind of bland and boring but let me tell you they are absolutely crucial when it comes to understanding the cosmos.

“Being apart teaches us how to be together”

No, I’m not talking about that kind of distance, or wait maybe I am. Either way, when it comes to distances in space, it’s a bit weird. We don’t stick with the SI unit for length anymore. We don’t use meters, and probably for good reason as well.

Now things in space…

Now, I just want to start by saying that this topic isn’t exactly an Astrophysics topic but there is a reason as to why this is one of the first topics taught in any Physics class, it is used extensively in almost every field of Physics. I personally really enjoy this topic and it’s quite crucial that you understand it. Apart from being one of the foundational topics, you can use dimensional analysis on your answer for any Physics problem to see if you have the right answer.

Woahhh dimensional analysis… are we going to be looking at like…

Logarithms…wow that sounds intimidating, fear not dear reader, logarithms are quite easy and very helpful when you master them. They have their uses in measuring sound as decibels, earthquakes on the Richter scale and even the pH balance. That sounds useful! So what exactly is a logarithm?

Logarithm has the best solutions to life’s problems. If the pressure is much high, make that your strength, get multiplied and plot some practical relevant equation. — Unknown

**What is a logarithm?**

Well let’s suppose we have the following equation:

*Introduction*

Ahhh vectors. It’s seen as a bland topic with fairly intuitive rules and formulas, however they are extremely useful in representing quantities and calculating values. Vectors are used in almost every field of Physics which is why it’s usually one of the first few topics. From velocity to displacement to even qubits (The quantum equivalent of a bit) — they can all be represented as a vector. So what exactly is a vector?

*Introduction*

Often times, trigonometry is seen as a chore, a class that people take for the sake of it, yet many don’t realise that it’s importance. Trig is used in many fields from architecture, to engineering and even astrophysics! While this article doesn’t expect you to fully understand trig, I hope that you would at least understand the basics of what trig is and perhaps even solve a few problems. However before we even continue, we must first ask ourselves, what is trigonometry?

Can you imagine young people nowadays making a study of trigonometry for the fun of it? Well…

I’m a 15 year old who adores Science, from the micro that is Particle Physics to the macro that is Astrophysics, everything interests me
