Hello, learners have you ever heard of the most complex subject in the known universe, one which is still far from being understood. One which is the literal cause of everything, one which is making high-school students hate school, and most importantly, one that made Rick and Morty possible. You guessed it right and probably know what I’m talking about physics and how

revolutionizing education.

Physics is a huge subject that covers many different topics going from galaxies in the depth of space right down to subatomic particles. If you don’t already know physics it’s difficult sometimes to see how all of these different subjects are related to each other, so this is my attempt to show that in a map for

Classical Physics

## Physics app

talks about Newton’s laws of motion, which describes how everything made of matter, moves about. His law of universal gravitation tied together the motion of planets in the sky with the falling of objects on earth into one elegant and general description. He also invented calculus as a supremely powerful mathematical tool, which has been used over the centuries to drive new physics. Calculus is really a part of mathematics, but physics and mathematics are inseparable.

Math’s is the language of physics and you can imagine it like the bedrock that the world with physics is built from. Newton additionally gained ground in the field of optics which is the material science of light and how it goes through various materials. Physics app explains refraction seen in prisms and lenses which are used to focus light, telescopes, microscopes, and cameras. Telescopes empowered us to look into the profundities of room and watch the wild cluster of articles there and create astronomy and cosmology.
Optics is firmly identified with the hypothesis of waves, which is fundamentally how vitality can go through unsettling influences of a medium like swells on the surface of a lake or sound through the air.
Physics app shows how lights don’t need a medium to travel, though it can travel through the vacuum of space it still follows the same principles as always namely reflection and refraction and diffraction.
This brought us to electromagnetism and the description of magnets, electricity or more generally, electric and magnetic fields. It was a physicist called James Clark Maxwell who discovered that these are two aspects of the same thing. He then derived the wonderfully elegant rules of electromagnetism which could be found on physics app, theorized that light was an electromagnetic wave. Electromagnetism likewise clarifies the greater part of the power.
Bouncing back somewhat traditional mechanics is identified with Newton’s laws and spreads the properties and movement of strong articles.
Fluid mechanics is the description of flows of liquids and gases using fluid mechanics, you can work out how much lift is generated from airplanes wing or how aerodynamic of the car is. Fluid mechanics is notoriously difficult, mostly because the motions of tiny things like molecules get really complicated really fast.
That brings us to chaos theory, according to physics app chaos theory is the description of large complex systems and how small differences in initial conditions can lead to very different final outcomes.
Thermodynamics is the description of energy and how it passes from one form to another. It also includes entropy which is a measure of order and disorder and basically tells you how using different kinds of energy are.
Energy is a fundamental property to physics and although I’ve written energy here, I should have written it everywhere on this map because everything has energy so that’s all of classical physics which could be understood from physics app.
The picture of the universe we had around the year 1900, it told us we lived in a universe where everything ran sort of like clockwork. If you could measure everything accurately enough the future was kind of predetermined. However, not everything was solved, there were just a few holes in experiments that hinted at something. The orbit of mercury was slightly too fast, and some strange things happened on the smallest scales with electrons and light, which were all unexplained. Physicists at the time thought that they’d solve and explain these problems soon enough but poking at them they unraveled the new domains of Relativity and Quantum physics and turned our understanding of the universe completely on its head.

Relativity

Albert Einstein was the genius who
developed the theories of special and General Relativity. Special relativity predicts that the speed of light is constant for all observers, which means that when you travel really fast weird stuff starts happening like time slowing down. It also states that energy and matter of different aspects of the same thing, through the famous formula
e=mc
2
(e equals mc-squared).
General relativity says that space and time are part of the same fabric of space-time, that the force of gravity comes from objects bending space-time making other objects fall in towards them.

Quantum Physics

While relativity describes the very big, other physicists were busy at work on a very small in the world of quantum physics. Atomic theory probed the nature of the atom, and more and more detailed descriptions of the atom were developed. From a tiny sphere to electron orbits, to energy levels and then to the electrons being wave-like charge distributions.
Condensed matter physics describes the quantum physics of many atoms together in solids and liquids and is where many great technologies have come from like computers, lasers, and quantum information science.

Nuclear Physics

Nuclear physics describes how the nucleus of atoms behaves and explains radiation, nuclear fission, the splitting of the atom used in our nuclear power plants, the nuclear fusion, which takes place in the Sun and will hopefully soon be harnessed here on earth.
Particle physics broke even deeper to find the fundamental subatomic particles that everything is made of and is described in the standard model of particle physics. In quantum field theory captures all of quantum physics and combines it with a special theory of relativity and it’s the best description of the universe we have.

The Physics we are yet to explore

Unfortunately, quantum field theory doesn’t include gravity and so physicists don’t know how to join quantum physics and the general theory of relativity together, leading to the giant chasm of ignorance. One day in the future we hope to close this chasm and come up with a theory of all of the physics we will call it quantum gravity. There are many attempts to do this, some examples are string theory or loop quantum gravity and there’s many more. But quantum gravity isn’t the only thing we observe but don’t understand, there are also the major puzzles of dark energy and dark matter which seem to make up 95% of the universe. So,
all of our physics only really describes 5% of what we know about and everything else at the moment is a mystery. There are many other mysteries out there like the Big Bang Theory, no doubt there are things beyond that like we don’t even know, that we don’t know which gets to the lofty cloud which floats over all of physics philosophy. Although many physicists make fun of philosophy, it’s the big philosophical questions that motivate a lot of physics, like,
• What is the fundamental nature of reality?
• How come the universe even exists?
• Do we have free will if we’re just made of physics? or
• How do we know that the way that we do physics and science actually gets to the fundamental truth of the universe? and
• Just, why is all of the physics like the way it is?
Well, those are rather big questions, ones which we may or may never answer, but there’s no reason to give up trying, after all, physicists are not quitters.
