I have been looking for a general all around math text since last century (as an amateur / recreational mathematician). I m starting to look at this. It seems to cover lots of ground. Any observations?

While there are a lot of of textbooks flown around, I'd like to prop up ROB201 textbook, which I came across recently, also aims to cover a lot of ground and is accompanied by videos.

https://grizzle.robotics.umich.edu/education/rob201 - "ROB 201 Calculus for the Modern Engineer"


If I were to write such a text, it would have a lot more about building intuition for advanced mathematical concepts. This intuition is extremely valuable, but missing from almost all advanced-level texts. On the other hand, it’s very difficult to put into words, and probably quite personal.

Subscription to Math Academy might be more suitable for that.

Red flags of Math Academy:

- Centred around AI

- Seems geared around edutech (which is what I gather from the site)

Green flags for Napkin:

- Covers advanced undergraduate and graduate topics

- Encourages pencil & paper way of learning (took me way too long to learn this is the best appraoch)


> Centred around AI

Where do you see the centered around AI? I have used it a lot and have not touched a single subject around AI.

> - Seems geared around edutech (which is what I gather from the site)

What is edutech and why is it unsuitable?

Finally, have you _used_ MathAcademy at all?


Where do you see the centered around AI?

From https://www.mathacademy.com/how-it-works:

> Math Academy is an AI-powered, fully-automated online math-learning platform. Math Academy meets each student where they are via an adaptive diagnostic assessment and introduces and reinforces concepts based on each student’s individual strengths and weaknesses.

What is edutech and why is it unsuitable?

I don't want a computer in the loop when I learn math, plain and simple. My preferred style of learning is instructor led with a mix of Socratic method and hand holding. But bar that, reading texts and using a pen and paper.

Finally, have you _used_ MathAcademy at all?

Nope, doesn't look like my cup of tea.


As far as I can tell, most of its value comes from having a reasonably thorough dependency tree of math topics and corresponding exercises (which can be solved with pen and paper) and describing it as "AI" is how you get investors to fund a math textbook.

The “ai” is an expert system yes to calibrate to your ability to answer questions it throws at you. The questions are all human written. I had your initial scepticism as well, I can reassure you that the ai is not an LLM. Also the guy Justin skycak who built it has put a lot of thought into its pedagogy

My experience with MathAcademy is very positive. So is my experience using ChatGPT 5 as a math teacher in learning mode. I'm as fed up with AI slop as most people, but for me this is a domain where it excels.


Try the Princeton Companion.

+1 this is a great reference text

There is no one book which can give you the overall sweep of Mathematics. However, you might find the following (though not textbooks per se) useful.

1) The Princeton Companion to Mathematics by Timothy Gowers et al. and The Princeton Companion to Applied Mathematics by Nicholas Higham et al. - The closest you have to a Modern Encyclopedia of Mathematics. You get unmatched breadth after which you can move on to dedicated books as needed. Well worth the money.

2) Mathematics: Its Content, Methods and Meaning by Aleksandrov, Kolmogorov et al. - Absolutely brilliant overview of Basic Mathematics. Published by Dover and hence very affordable.

3) Elements of Mathematics: From Euclid to Gödel by John Stillwell - Written as sort of an update to the great Felix Klein's Elementary Mathematics from an Advanced Standpoint books. The Topics are particularly well chosen given modern advances; they include Arithmetic, Computation, Algebra, Geometry, Calculus, Combinatorics, Probability, Logic.


Ask and maybe some one will look it up on Wikipedia.

Isn't this big news? I am looking for more information (how far away, closest approach and such).


None of the planets listed (I may have missed something, let me know) have rain. Here on Earth Antarctica is a desert even though it is covered with water (https://en.wikipedia.org/wiki/Climate_of_Antarctica).

First time I have ever heard "zettaliter" That is a lot of water bottles.


I am glad it looks like Waymo is taking safety seriously. If they are getting into fewer crashes (serious or not) that is a good thing. It is worth remembering, imho, that the ability to avoid a crash, whoever is at fault, is an important skill also. I hope they keep working at the self driving and continue getting better with their safety record.

I also hope they figure out how to keep the wheels from falling off. How did this happen? Does it happen often (to any class of vehicle)?


There is not a Nobel Prize for mathematics so treatment:)


I wonder if the workers had he opportunity to go back to where they were staying to collect their stuff before being sent back?


Also, (speculation warning) it could be the government paying for airline seats to "keep them available" is a kickback. That is, lobbyist paying government officials for a contract that is not needed.


Sound like winners.


Looks like a high quality study, albeit small. There is a good summary here https://www.newscientist.com/article/2494421-bespoke-brain-i...
