Description

*** The Bestseller for quantum physics & Part of the udemy business collection *** 

"Phenomenal course!! Prior to this course, I thought I would never be able to understand quantum mechanics. I would certainly recommend this course to anyone that is interested in learning quantum mechanics.“ - Maximus Akrem Nwider

"I have learned more theory here than in a semester in a university course. The information is incredibly well organized. I cannot express the insanely good quality of this course." - Aaron


This course is for everyone: beginner to expert!

We will cover the whole band width of quantum mechanics starting from the initial experimental observations and ending up with relativistic quantum theory.


Quantum mechanics is arguably among the most fascinating fields of science.

It has made numerous appearances in modern pop-culture and is present in our everyday lives. Still, it is also very challenging to get a grasp at this topic - even understanding the most fundamental concepts can be very difficult without instructions.

However, I think that this most fascinating field of science is often taught either too vague or with a too strong focus on the mathematics. Instead of watching random Youtube videos or going through hundred of hours of university courses, I think that Udemy courses are a nice platform for purposeful learning. You are kindly invited to join this carefully prepared course that will teach you the 101 of quantum physics.


Why me?

My name is Börge and I am a postdoc working as a scientist in quantum theory. Due to my expertise in the field (more than 10 years), I know which topics are most important and which parts can be cut short (especially the very dry parts). I have not forgotten the time when I learned about quantum physics and still remember the problems that I and other students had. I have refined my advisor skills as a tutor of Bachelor, Master and PhD students in theoretical physics.


This course is for you if you ...

  • ... have ever wondered what is the big deal with quantum physics

  • ... want to know why we need quantum physics

  • ... want to learn the methods how to actually calculate quantum problems like the tunnel effect

  • ... want to walk comfortably in the quantum world without being totally overwhelmed by its difficult language

  • ... have interest in popular physics phenomena like quantum computing or superconductivity and want to understand their core ideas and relations to quantum mechanics

  • ... are about to attend a university course

  • ... if you have already attend a university course and want to learn what comes next

or

  • ... if you simply want to have a carefully condensed refresher before your exams :-)

I should have started with the math review of section 4. The instructor’s voice is monotone and puts me to sleep. I wish there were some more actual videos of interactions instead of just slides with equations and formulas. The different constants and variables should be explained better so we can get more intimate with them. Some are new and some review for me. The material is great, but the approach is really difficult for me to stay engaged. I will keep watching and studying though.

It isn't beginner friendly as the title says. You need to be already aware of the topics being taught, to grasp them. This course is more like a revision of the concepts.

I loved it! I had a lot of fun learning about all the fundamental for the QM, evethough the subject is very difficult, the way is explained is very friendly and interesting. Thank you for the course!

Yes I have always been interested in Quantum Physics and am familiar with the concepts but didn't know the Math behind it.

A beautifully and carefully explained first lecture - augurs well for the rest of the course. I've finally learned the derivation of equations that I've previously just glazed over in popular physics books!

It certainly is interesting, but also complex and a bit hard to understand I am only a 10th grader lol

Unfortunately it's too difficult for me and i will have to dig to even more basic program to understand the equations. I want to follow this course for pleasure of learning only thus it's not a problem however I regret that my level of knowledge is insufficient.

I think in general it is totally what I expected! Some detailed remarks: -> The added resources (exercises mostly) are in png-format. Pdf would be nicer and some nicer formatting (title etc) could be considered. -> I do better on the quizes then, I think, my level is; the quizes are a bit too easy I think.

Very clear. Very good visualisation. Very good way to keep focused. Good as a basis for Leonard Susskind (for example). Which is also a good basis but more difficult to visualize the mathematics in your head and see the relations.

Initial review: The course topic stated that it is from beginner to expert, but there was no build up to it, it directly started with equations without any explanations thereof to make sense of it. Halfway review: This course continues to disappoint, hence I have increased the rating only by a bit from 1 (Awful, not what I expected at all) to 1.5 (Awful / Poor). The reason for such low rating being the misnomer to the course title - 'Quantum Physics from beginner to expert', it doesn't start at the beginner level at all, it directly starts at intermediate-to-advanced level, which in and by itself is nothing wrong, but to market it as being a beginner-to-expert level course is misleading and deceptive. The instructor should have labelled this course at a minimum of intermediate level, and if he were to be so interested float an introductory/beginner course as a separate one.

An amazing course in quantum mechanics. All explanations are very clear and orderly, exercises are really good to see whether you have already understood the topic. If you already have a background in quantum physics, you will enjoy the entire course; otherwise, you will probably run into some problems in the later lectures.

yeah I learnt partial differentiation in HS and also dot and cross products in uni so its' not that hard.

I’m eating a cosmic crisp apple realizing I never knew how much I do not actually know. Doctor Borge is a treasure box with the mind of a jigsaw puzzle who is explaining to me why I should have paid attention more in classes when I was younger. Thermodynamics and theoretical quantum mechanics are two topics I am now genuinely interested in thank you Udemy y’all the coolest

I am a software engineer, but deep down inside, I always study physics out of curiosity. And I find this course a gateway into what I really want to do with my life. Thank you very much, Dr. Borge Gobel!

This is my first course in Quantum Physics/Computing and being a software engineer, I can clearly say that I belong to this subject.
