Private coding / programming lessons with python
Python is one of the best, if not the best, language to start learning programming. It is also one of the most widely used languages today, especially in cutting-edge areas such as machine learning. This popularity means that Python is constantly evolving. It offers a wide range of tools and libraries, which are free and very varied. As an aeronautical engineer, I like to share my knowledge and derive satisfaction from it by teaching and motivating others. I'm used to working with people of different ages. I believe in the importance of segmenting learning, visualizing progress, setting concrete goals and practicing regularly. Beyond these general principles, there is no magic rule or method. Some approaches work with some students but not with others. Adaptation to individual needs is therefore the main objective of private lessons. So I will do my best to find what motivates and helps my student.

Graduate teacher gives courses in Physics & Chemistry, Mathematics, many years of experience.
I am a dynamic and demanding teacher who gives private lessons in Physics-Chemistry as well as Mathematics. I graduated from teaching seven years ago, after a masters in physical sciences with honors, and I teach in college and high school since. I have also been preparing students for the Baccalaureate Science for many years, all of whom have been awarded very good honors. I also prepare my students for different exams (Matu, Bac, preparation for EPFL, etc...) I make sure to rework the basics so that the student can progress quickly. It is important to me that my students acquire a solid foundation of knowledge. I also give effective work methods that will allow him to progress much more quickly and so he can regain self-confidence. I can go to the student's home or also take the course via Skype.

Logic, formal languages, and automata theory for computer science
Experienced and patient teacher of logic for computer science. I have taught logic, formal languages and automata theory to undergraduates for six years. My tutoring is adapted to the student's level and goals. Whether you need to learn logic for your studies, or you would simply like to know more about the subject, I will be more than happy to help you improve your understanding and skills. Logic The sciences presuppose a certain standard of rationality. An ability to distinguish between correct reasoning and claims that do not follow from the assumptions. In this class we study the basic principles of logic and apply mathematical techniques to the study thereof. Topics include: Propositional and Predicate Logic Syntax and semantics Semantic Tableaux Natural deduction Correctness and soundness Completeness Formal languages and automata A formal language is an abstraction of general characteristics of programming languages. Such a languages consists of a set of symbols together with some rules to determine whether a string made up out of those symbols is a member of the language. Topics include: Regular languages, context-free languages Finite automata, pushdown automata, Turing machines Regular expressions Regular grammar, context-sensitive grammar Pumping lemmas for regular and context-free languages
