# Top Ten Hardest Physics Topics

Physics is number one my best things to learn. But, there's something that you may fed up when you learn them.### The Top Ten

*1*

**Quantum Mechanics**

I love physics but to say some of it's laws are just too much hard. Best example is quantum mechanics. Just make your mind tiny to understand it. It's okay to say that it's very interesting topic.

Well, Niels Bohr said that anyone who is not shocked by quantum theory has not understood it. Quantum Mechanics are fascinating, but I know that even the greatest of minds see it as hard. I love Quantum Mechanics from Heisenberg to Schroedinger.

Ok, here's a tip of mine of grasping QM: You don't have to use common sense to grasp it, it deceives you; You have to make your mind flow on thin paper.

Most exciting topic in physics ever. You can't go bored in the microscopic world.

*2*

**Electromagnetism**

Classical mechanics and fluid mechanics were pretty interesting compared to this; electromagnetism can get quite monotonous involving all kinds of directions and lengthy calculations which we did without a calculator, it just made sure that we don't find this interesting.

It took time and patience to learn this properly, and even then, I'm confused when to use the Left-Hand Rule, and when to use the Right-Hand Rule. But it's more interesting than any other topic, definitely.

EM is the basis of almost everything, yet there are not too many good professors who can teach it in an intuitive manner. So definitely the hardest topic, hands down!

First test that I failed in engineering, congrats electromagnetism.

*3*

**Projectile Motion**

Projectile motion, while being one of the first things students learn in physics, is actually one of the most difficult to grasp and enigmatic entities in the entirety of physics. Richard Feynman once said, "Projectile motion. A topic of immense importance and of utter confusion. If you throw a ball with a known initial velocity, and you know something about the medium it travels through as well as gravity, you can know exactly where it will land. How in the world does this work? It is enigmatic". The true mysteries of projectile motion are still yet to be discovered and can only be postulated as of today's research.

I struggled so much with projectile motion. I think it must be one of the hardest things besides Newton's First Law. Maxwell's Equations were wicked easy though, I don't understand why we don't start with those.

If a body follows projectile motion, that's not my problem then why should I be bothered about its x and y components?

Projectile motion is not hard, its fairly easy. I would say quantum mechanics is the hardest

*4*

**String Theory**

How does this not top the list, the amount of mathematical rigur needed to even begin understanding this is at a master's or PhD level in theoretical or mathematical physics, this is completely outside the learning experience even for people who study pure physics.

One of the most specialist areas in all of Physics. Most of Physics, nailed it and love it, but String Theory just drives me this way and that! But it's still awesome, despite the fact that it's entirely mathematical and isn't tested yet.

You need to master Quantum Mechanics before even think to start into string theory, and even then, is very hard to fully understand it.

I love this theory because it Theory of everything

*5*

**Electronics**

All is easy with practise any thing can be east

*6*

**General Relativity**

Indeed Einstein's field equations are difficult to understand. I will just say that it's not even included in the mandatory part of a regular Physic's degree (Special relativity is) because to grasp the noumerous concepts it contains you require many other advanced subjects first (tensor calculus, partial differential equations (these come after ordinary differencial equations, special relativity, and also a very good undestanding of waves (ie armonic oscillators and vibrations, electromagnetism, optics). So you may understand Wikipedia's General relativity website, but to fully comprehend the equations and their implications is another story.

It is a very interesting topic to learn, but also very confusing at times, the hardest of any other theory of relativity. I don't think you can learn it just by reading, you need to see what happens with animations just to get a glimpse of what's happening, unlike many different topics in physics.

Very hard to grasp

*7*

**Relative Velocity**

This topic has always made me suffer in physics. Rest of all the topis mentioned are quite easy. This is not a topic in modern physics. Slope problems are damn easy

*8*

**Radiation**

It's actually not difficult, if you love the amazing world of physics.. then it's certainly not ( trust me it's great )

It is interesting

*9*

**Force**

The interaction between objects is known as force. It may be push or pull ( it depends on the nature of interacting objects)

Who put this thing in here? It is elementary level Physics.

I think this was put on here by a primary school pupilâ€¦

Electric bill

*10*

**Rocket Science**

U know the saying .

Very difficult

### The Contenders

*11*

**Thermodynamics**

Like I will argue this one is as hard as QM. But the equations aren't that hard, thankfully. Still failed this stuff

Man this is the best yet one of the most difficult in physics

The first law is wrong

Best and interdisting

*12*

**Motions**

Extremely hypothetical

*13*

**Black Holes**

What you need is fantasy and patience. If you have these you are in good way.

What a fantastic topic but need patience to understand

Fascinating young topic

Just think about it...

*14*

**Astronomy**

So much out there that even college can't cover it all. It's something so amazing if enjoyed and studied well, but it can be tricky!

Can be a lot tricky... but is a heck lot amazing when you feel it..!

*15*

**Dark Energy**

Waste of reading time

It is the most difficult

As don't have much information about it

And there is so much for imaging about it

*16*

**Pressure**

Hardest ever

*17*

**Classical Mechanics**

Just one word.."TOUGH! "

*18*

**Simple Harmonic Motion**

Once understood. Nothing can stop you

The worst and most difficult topic ever! tons of formulas, no matter how hard I try, I just can't understand it. :(

*19*

**Electricity**

Just understand the concept.

It is the best branch

Electrons have dual nature same as light

Actually this is vast yet very easy if you use the Laws in a practical manner like Maxwells laws,Flemings law,Ohms law etc.First understand the concept android try it practically it will sink in your brain.

Go to hell kirchoff with your laws...i can't even identify a wheatstone bridge and tomorrow's my physics exam...i'm gonna fail...i guesss!

*20*

**Chaos Theory**

*21*

**Special Relativity**

What's the meaning

*22*

**Cosmology**

*23*

**Waves**

They are a bit difficult

*24*

**Virtual Particles**

*25*

**Statistical Mechanics**

Classical vs Quantum statistics, then Quantum vs Quantum statistics, again Quantum vs Quantum statistics. Bosons vs Fermions vs Classicals. In the game Metal Gear REVENGEANCE (2013) Jetstream Sam's sword works on Fermi Dirac statistics.
