**We are coming to you with 20 new resources on Real Not Complex. We have both new textbooks as well as video lectures. As always, we hope that you will find here something for yourself.**

Everyone knows Khan Academy and Professor Leonard. But there are many overlooked (relatively speaking!) creators out there. TheTrevTutor is one of them. He has high quality content on the topics of:

All of those are now part of Real Not Complex.

Similarily, we discovered great lectures from a channel MathTheBeautiful:

- Partial Differential Equations, which is a first video lectures entry in Partial Differential Equations section.
- Linear Algebra lectures, which consist of literally hundreds videos and are going incredibly in depth on the topic.

We have a big update in that section:

- Already legendary Deep Learning by Ian Goodfellow, Yoshua Bengio and Aaron Courville from MIT.
- Foundations of Machine Learning, textbook by Mehryar Mohri, Afshin Rostamizadeh and Ameet Talwalkar.
- Bayesian Reasoning and Machine Learning by David Barber.

This sections also gets quite a big update:

- Famous Book of Proof by Richard Hammack, teaching proof writing and basic Logic.
- Logic Self-Taught: A Workbook by Katarzyna Paprzycka, which seems like both a gentle and very "hands-on" introduction to the topic.
- Delftse Foundations of Computation by Stefan Hugtenburg and Neil Yorke-Smith, which - contrary to the title - does introduce a lot of basic Logic, Proof Writing and Set Theory.
- Lecture Notes in Logic by Yiannis N. Moschovakis.

We have two new resources here:

- Classic textbook Measure, Lebesgue Integrals, And Hilbert Space by A. N. Kolmogorov (!) and S. V. Fomin.
- Measure Theory video lectures from YouTube channel The Bright Side Of Mathematics

We have added:

- A textbook Concrete Algebra With a View Toward Abstract Algebra by Benjamin McKay which tries to "warm up" reader to the ideas of Abstract Algebra.
- Video lectures Visual Group Theory by Professor Macauley which represents a very interesting approach in teaching Abstract Algebra.

We have added a textbook Differential Geometry: A First Course in Curves and Surfaces by Theodore Shifrin.

We have added Algebraic Geometry lecture notes by Geir Ellingsrud.

Apart from already mentioned videos of TheTrevTutor, we also added a textbook Lectures in Discrete Mathematics by Edward A. Bender and S. Gill Williamson.

We have added a textbook Enumerative Combinatorics by Richard P. Stanley.

I hope you enjoyed this update and found something interesting. See you soon!
