  • This course builds on basic level mathematical knowledge.
  • Only integration shall be known from university level mathematics.
  • The course starts from scratch in thermodynamics, NO prior knowledge is required.


This course is a comprehensive overview of engineering thermodynamics. By taking and finishing this course you are going to succeed both at university exams and engineering practice! You are going to get the answers for both your theoretical and practical questions!

I start every topic by introducing the theoretical background but as soon as possible I switch to the practical applications. In this way you are going to get a strong theoretical basis but more importantly you are going to be able to apply that knowledge! At the end of each section, there are checkpoints where you can test yourself. Of course, if you are stucked, you can revise the lectures any time to find the answers for any problem!

You don't need to know much about anything to take this course as I introduce all details also in everyday language, in an easily understandable way. From university level mathematics I only suggest knowing integration beforehand as it appears in the calculations multiple times. I have great expertise in teaching practical knowledge and preparing students for exams. If you need help, you can trust me, I am going to help you! I'm always here for you in the lectures but if you have any further question, I'm happy to answer it!

This course is primarily designed for engineers so I highlight the technical part of thermodynamics. If you are not an engineer but you are interested in the topic, then please check the curriculum. Based on that, you can easily decide whether this course fits your needs or not.

I hope I can help you with this course and I just can't wait to see you inside! Have fun and learn a lot!

Who is the target audience?
  • The course is primarily designed for engineering students, it is focused on the technical part of Thermodynamics.
  • If you have any problem understanding Thermodynamics, then it is your course! The theoretical lectures are going to help!
  • If you stuck with solving Thermodynamical problems, then it is also your course! The sample problems are going to be extremely useful!
  • If you've already learnt thermodynamics but the details are shady, take this course to revise Thermodynamics!

Mechanical engineer


Welcome to my page! :)

I'm a mechanical engineer and an online entrepreneur. I'm already teaching more than 1500 students worldwide and I look forward to see you as my student, too.

Besides my engineering and mathematical profile, I'm committed to honor my Hungarian heritage by introducing Budapest and Hungary to everyone around the world. I'd love to bump into you in Budapest so I designed my Budapest courses with my engineering preciseness to give you the ultimate experience!

I've got my MSc level degree in mechanical engineering at Budapest University of Technology and Economics and I'm enthusiastic about sharing my knowledge and my love of engineering sciences.

I've been teaching and helping mechanical engineering students as a private tutor in various subjects for 3 years. Therefore I not only know how to understand a topic as a student but also how to make it understandable for others. I passed most of my subjects with an excellent mark and I hope I can help you to reach the desired mark or objective for yourself by ease, too. I offer guidance to understanding either if you are a student or if you want to refresh and widen your knowledge as an engineer in practice.

If you can trust me and follow my courses, I can take you from beginner level to be an expert of mechanics enginnering related topics. I came far on this road and I wish you great success, too!

I'm looking forward to welcome you in any of my courses! It would be so much fun and honor to me to help you worldwide :)
