I actually find the outdated textbooks simpler and easier to understand. Sure the information may not be entirely accurate but it's enough to get you started.

This is one reason I really liked my Dynamics professor. On the first day of class, he wrote "F=ma" on the white board and said, "See that equation? It hasn't changed much in the last 200 years. You don't need to buy the newest edition of the textbook; it's mostly just fixing errata. The lessons are virtually the same as the first edition."
Okay, but do I really need to draw this many circles to prove what value Pi has? Also, it's all in Greek.
watched a video on tensors with 'no math'. dude lost me in analogies. matrix vectors sumthin... brain is failing. no really the math is advancing more than that with computers and better theories for the physics experimenters.

Now for applied mathematics on the other hand...
The textbook:
“After the likeness of [this] angel. He made the incorruptible [generation] of Seth appear to the 12 androgynous [luminaries. And then] he made 72 luminaries appear in the incorruptible generation according to the Spirit’s will. Then the 72 luminaries themselves made 360 luminaries appear in the incorruptible generation according to the Spirit’s will so that there’d be 5 for each. And the 12 realms of the 12 luminaries make up their father, with 6 heavens for each realm so there are 72 heavens for the 72 luminaries, and for each 1 [of them 5] firmaments [for a total of] 360 [firmaments. They] were given authority and a [great] army of angels without number for honor and service, along with virgin spirits [too] for the honor and [service] of all the realms and the heavens with their firmaments.”
Indeed. There is a reason I gifted my son, who studies math, Euclids book 'Elements'. It is still relevant.
I think you'd get better traction out of this if it said quantum mechanics
