🌌 Ilmu 'Fisika' Itu Sebenarnya Apa Sih? #BelajardiRumah

Physics, yes our world is controlled by physics. Gravity that attracts all planets in the universe, flying planes that can fly and not fall from the sky, bicycles that can keep going in balance, everything is controlled by physics. Yes, it can be so wide because physics is science that unlocks how the universe works.

From the smallest matter in the universe to super-large objects like galaxies. Trying to trace the beginning and end of this universe, to predict the end of everything. But it also helps how things can work every day, including things that break the boundary of intellect. Physics is knowledge about everything. Welcome to the science that regulates everything in this world.

Imagine studying physics like you're a detective. With the existing tracks, we inferred why a phenomenon could happen. That's how Newton found that this world is controlled by an invisible power called GRAVITATION. He just tried to be a detective. But the case is the universe.

That's just one, there are still many others. But the universe is already like this from the beginning. Only we need to find the rules by continuing to follow the traces of mysteries that exist, like Newton. With more and more universe rules that we find, the more technology we can create for our lives.

But before we continue, try to answer this question. What do you imagine if you hear the word magic? Maybe what you imagine is like this. But do you believe it or not, through physics, actually the real magic can be created. Wifi, GPS, or telephone are not visible.

But this invisible thing can make us talk telepathically to people in other parts of the world without any connection. So it is also hundreds of humans who can fly like birds, or a horse carriage that can walk without a horse, or a thing that can talk. All of that is magic. And it turns out to be surprising is that it's just how the universe works.

Through the great detectives and their weapon named Physica, we managed to find it. And what's more surprising, there are still many more spells that we have not found in this universe. Okay, so Physica is very wide, but if you want to learn where we started. Let's start from here. Classical Physica with the character of the invader, Isaac Newton.

This field is the most often taught in school and is a very useful physical branch in our daily lives. Through these branches, the world is like a machine that we already know the secret. Everything in this world can be predicted through physics. Until the 1900s, this is the limit of how we view the universe. But then, a mysterious thing happened.

The planet Mercury orbits the sun faster than it should be, and so many strange things happen on a very small scale. Physicists suspect that there is a trace that shows that there is something bigger out there. Something that can not even be explained by classical physics.

The physics detectives also tried to find this trait. And it's true, they found two new areas of physics that are not yet complete and super crazy. Relativity and quantum physics. Relativity was found by the genius Albert Einstein. This theory is so enthralling and changes the understanding of anything we ever knew about the universe.

So Einstein found that our world is not an object that attracts each other. Rather, our world is actually shaped like fabric. Imagine that the empty space is this fabric. If we put a heavy object, then our fabric will be pressed and become bent. Then because it is bent, other objects around it will fall and create a gravitational effect.

It sounds like nonsense? That's just the beginning. It turns out that the fabric of our world is also tied to time. The more our fabric or space is bent, the slower time will go in that area. For simplicity, imagine you are on a luxury plane, then passing through a super bent space. You will experience a slower time than passing through a straight space. The point is, time can even be bent and manipulated.

This relativity is what managed to break the mystery of the strange problem of the Mercury's orbit, to make it possible for us to have a super accurate GPS. But in other fields, many detectives also point out the opposite. Quantum physics points out how the super small world that arranges us all works.

Again, what's surprising is that many things are not in the mind happen in this super small world. For example, an object, namely an electron, can be in two places at the same time. And also can have two bodies at once. Yes, really crazy. Although it sounds like a fiction movie, but the screen you see now and computer which is the basis of modern civilization can be born because of our knowledge in the quantum world.

But then the challenge in this super small world, many regulations in classical physics and relativity are not working. This causes a problem where our understanding of the world is still like a puzzle that is not complete. So we are in the mystery of our universe right now.

The detectives still find theories that can combine everything. None have been successful so far. There are still many mysterious traces left. One of them shows that we have only found 5% of the rules of this universe. If most of the universe detectives are outsiders, meet the universe detectives from Indonesia.

Mr. Hussein Alatas loves physics thanks to his junior high school teacher who described physics as a big mystery. Then because of curiosity, he finally even bought and read books of physics at college level. Of course he didn't understand at that time, especially the formula. But he kept reading and reading without confusing any calculation. Because he was so fascinated with the mysteries of this universe that had not been broken.

And behind those books, Mr. Hussein found a name book. A book that inspired him to become a great detective. I went to high school, and in high school I still had a passion for music. So when I bought the book, it was a book called "Parsutrisno" in ITB.

So behind him there is his name, right? I read it, Berkeley graduation, he took nuclear physics. I immediately imagined it. At one point I have to be like him. That's the way of time, high school. It turns out that I entered ITB physics. I met people who

I have read the writings of the students from the junior high school. I can mention the names of Mr. Sutrisno, Mr. T. Holiong, Mr. Pantur Silaban. Then I met all of them at ITB.

In the Gawel language, it's called "Dreams come true". For 15 years, Mr. Hussein never got tired of asking questions and finding out about this universe. Until he finally got his doctorate.

Then, through his years of research on the mysteries of the universe and also educating the next detectives, Mr. Hussein was finally considered as a great teacher. Yes, a high rank that can be achieved in the academy world. All of that was done by one of the main components, his love for the mysteries of physics. He also has a mission to print the next universe detectives.

If he falls in love through books, in the future, physics can also be taught through movies. I also like the imagination of Star Trek, Star Wars movies. Then the most realistic movie was Interstellar. That's the most realistic of all the movies there was. Then the last one was Avengers. I know it's wrong. Fiction.

One thing that we can learn from physics is always follow its roots. Like the detective.

Not only for physics, this principle will be useful for your whole life. This principle is also what developed physics which was initially only said as a theory, becomes a science that can be so useful through technical science. From space travel to robotics, to making video games, to the need for defense. All of them need the physical knowledge.

And the physics will be the burden for the universe's detectives to continue to uncover more of this universe's mysteries that seems to be more and more unthinkable. It is precisely this mystery process that Einstein called the physical movement. So for those of you who like to ask about the universe's mysteries, don't be afraid to chase physics. Join as one of the universe's detectives.

Then, get ready for the next episode because we will discuss a science that can mix the elements of this world into something new that we have never imagined. This is it, chemistry.
