   I wonder if it might be possible to get back to "Nullius in verba" in modern day... Imagine if all the aspects of "settled science" came with instructions for simple at-home or basic-lab setup that could reproduce the r

   Oh and for even more linear algebra stuff, here is a 30 min condensed video tutorial that introduced most of topics in a standard LA course, also using SymPy to show demonstrations: https://www.youtube.com/watch?v=2G3PmEZI6n

   If anyone wants to try things hands-on, I highly recommend the SymPy (in particular the online live shell https://live.sympy.org/ ). The `Matrix` class can be used to create matrices (lists of lists of numbers) and vectors

   I've watched a few talks and seen cool computational demos about it (see for example https://news.ycombinator.com/item?id=22282452 ), but I still don't really understand it... or should I say I can't "we

   Thanks for taking a look and reporting the issues. I'll add clarifications around the "immediately" and remove the second "complete" as per your suggestions.

    Yes, totally agree. I was thinking of notebooks strictly as the first contact... get the notion of python commands, variables, syntax, etc. It would be great to "move out" all the working code that has been REPL-tested into a sepa

    I would recommend you learn Python or JavaScript first and use an interactive coding environment like a Jupyter Notebook, because it will allow you to try different inputs and see the outputs (or errors) immediately. Learning/exploring

    You might want to check out my linear algebra book. It has standard LA topics, but also goes into more advanced topics in the last three chapters (e.g. probability theory and modular arithmetic). See extended preview here: https:/&#x2

    That was a nice introduction to the concept of induction: the idea that patterns observed in our past experience will hold in the future. Since we're talking about induction as the basis of science, I'm surprised the concept of &q

    Yeah, that's a lot of jargon associated with Bayesian statistics, but at it's root the idea is simple. How to merge information you have before observing some data (a.k.a. prior) with new information you just observed, to obtain u

    Does anyone have a geometrical intuition about how this works? Maybe just for 3d case? How does condensation compute the volume of a parallelepiped from the individual areas of parallelogram? And what does the division do?
