  1. Thank you so much for this webpage. Im a junior in Electrical Engineering and I found multiple books written by you on amazon. I couldn’t help but research you even more, because even after various calculus-based physics classes, it is always useful to go back to the foundations and see how other people explain/see the physics world through their eyes. I, myself, loved the way you explained basics of electrodynamics. A great man once said that if you can’t explain something simply, then you don’t truly understand it.

    Also, as an engineering student myself, I do still have trouble with physics, and I love to see it all explained again in a very simple manner.

    Thank you again,

    1. Hi Alex,

      Thank you so much for taking the time to let me know! I am very happy you like my books and found them helpful. It helps me feel like I should continue writing them 🙂 Were there any other topics you wished I had books on, or is there anything else I could help you with?

      Good luck with the rest of your degree!


  2. Hello again,

    thank you for answering so quickly. I have not had the chance to see all your books. However, many people hear the phrase Quantum physics and they right away assume is something incredibly smart and out of reach but in reality the Quantum world is rather theoretical and in many ways unexplainable. A simple introduction to optics, photoelectric effect, refraction and reflection would be helpful to cover along with the relativity and basics of quantum physics. I know this is a rather complicated topic but enthusiasts like myself would like to at least see the modern physics explained in a simpler manner. I would love to see how you come up with a great simple explanation with pictures and analogies whether you make it a book or a blog!


    Refraction, Reflection, Wavelength, Frequency, Indexes, photons, photoelectric effect and so forth.

    1. Thanks Alex! That’s a good idea. I’ve been thinking about doing something along those lines, but I wasn’t sure if people would be interested. One thing I find hard is the difference in physics between explaining how something works and why something works. I always want to know why things are the way they are, but often in physics we only know how they work. I feel like that’s especially tough with modern physics. (But, also kind of fun and amazing and ridiculous 🙂 I’ll take a crack at some optics blog posts.

  3. That’s a very interesting fact that you bring. Science describes in a way we can understand how everything around us works, but the WHY it is this way is rather a clash of science and religion, yet unexplainable. I often think what if someone could come up with a system to understand things simpler and in a way deeper than the science we use to describe it. Such as describing why a chemical reaction, mechanics, electricity and so on occurs but using a different ideology away from the system we have created.

    This system of numbers and ideas that we currently use tho beautiful and perfect in a way, is very extent, complex, and perhaps limited to describe things that might be simpler or just completely chaotic.

    I like to see it this way:
    two programmers are told to create a program that can sum and subtract numbers. One programmer, a week later, shows up with a debugged algorithm, in which it has written only 6 lines of code and works flawlessly. A week later the Second programmer shows up with a debugged and full working program that has over 50 lines of code!

    they both got the same result but the second programmer failed to see the simplicity of the algorithm. This I relate to our Intelligence, maybe if we were on a different level of consciences and we weren’t bounded to this physical world, we could maybe then explain all this physics in a very simplistic manner that may lead to a solution of how it all works this way.

    is it purely chaotic or do is there a superior being controlling the balance.
    is everything random or predetermined.

    Lastly, I have read very little of quantum physics myself, and I do not consider myself an expert in anything in any way but so far what I have read about modern physics is that physics at a molecular level is very chaotic and random or simply hard to detect a pattern.

    I myself, bounded to these human limitations and nothing else, believe that everything at plain sight seems vague and dull in comparison to what is constantly going on at a molecular level and I would agree on a superior “thing” “being” manifesting itself on us. Thus space and time is infinite, leading to infinite/parallel-endless truths.

    I hope I did not bore you with this.

    1. Wow! That is a lot to type on a phone 🙂 Your ideas are very interesting, and I like the quote you end with. It makes me wonder what it means to ‘understand’ something at all. It’s crazy how different things are at a quantum level, and it boggles my mind thinking that here I am sitting in a coffee shop with my laptop sitting on a table, but the table is made of atoms and so is my laptop and those are made of electrons, protons, neutrons, quarks, and that until observed those electrons aren’t even in one place but are instead probabilistic-ally distributed. I don’t know much about particle physics at all. It’s fun to think about, though, and the interplay between science and religion. Also, I love the idea of space/time being infinite. It feels like it must be, but then I can’t imagine something that’s infinite, but I also can’t imagine it ending. It’s fun to think about. Also, I guess that is a question that will always be there. I wonder if there’s a way we could prove the universe to be infinite. It seems like we could prove it not infinite, if we had been everywhere. Or, at least maybe be reasonably sure we had been everywhere. Although, who knows, maybe we would still have missed something. But, if we haven’t been everywhere, we will never know how much more is out there. Fun to think about.

  4. Also I apologize for the grammar errors, I’m writing from my phone and I had to erase quite a few things.
    Also! what I meant with space and time being infinite is that in the end we don’t truly know anything.

    “I know that I know nothing”

  5. Dear Sarah,

    I read your book about work, energy and power on Amazon. I´m trully happy I did that cause it helped me understanding some basic topics on an easy way. I’m 24 years old and I’m from Portugal, Europe. I also have a Degree on Management which you might ask what the hell I´m doing here. The truth is that I´m thinking about taking a degree on Physics or Mecanic Engineering. From the last months, I´ve been reading a lot of books about Physics, Science in general and stuff related and I’m ready to loose my fear for Math and finally do it !

    Note: Sorry for my English but I´m a “noob” on this language =)

    Thank you for everything,

    Keep the good work!

    1. Dear Gabriel,

      Thanks so much for your message! I’m so happy you liked the book! That’s awesome that you’re thinking about doing a degree in Physics or ME. Good luck!!

      All the best,
