I guess that was written at a time when people with fairly poor education were thrust into jobs that required a sophisticated level of understanding. Members of my family moved into mana, accounting, farming, radar, sonar, navigation, gun sighting, and so on. After the war some (mainly women) went back to the previous occupations. Others were propelled forward because they understood trigonometry, physics, electronics, etc.
What a great book. I did an apprenticeship as a machinist in the 80's and some of it was still taught then, especially all the screw cutting maths. As you enjoy collecting do you have the Wolfe and Phelps shop maths books? They are great too.
Studying mechanical engineering, we delve as well into the thread / fits/speeds and feeds calculations. A lot of this looks familiar. Versatile book, cool stuff.
There are some TM 9-2820s on eBay, mostly for about $30 US each it seems. As it's a US government publication, though, it should be legal to disseminate the contents for free online. If the Internet Archive gets a copy it should be able to make it freely available. 4:12 , 5:24 : I assume that most of this stuff (updated and expanded with metric parts and so on) is still very much on the curriculum for the machinists who produce metal parts based on a mechanical engineer's drawings. You also can't avoid entirely avoid maths in carpentry either, especially if you're a master carpenter on structural-carpentry jobs. Wood's actually tricky enough as it expands and contracts in extreme and uneven but somewhat predictable ways: you'd need a combination of reference tables and some maths to calculate the necessary margins in some applications. Overall, books like these are probably a fairly good way to encourage secondary-school students to stop moaning that they'll never need algebra in "real life".
It is a regular book of 1940s )) Time makes this book special It is nostalgia, when you open such a book and feel warming feelings This one is still available on ebay as used physical copy, but not in torrents or internet archive
If someone sends a copy to the IA they'll scan it, and since it's under US government copyright they'll probably be able to share the contents without restrictions.
I'm learning about the Arduino platform to teach myself electronics. I've always been creative but was not all that interested in any of this stuff until recently. I don't expect it to be easy or effortless, but I'm still excited to expand my creative horizons when I eventually get a better grasp on the paradigm. It's given me more opportunities to do math, which led me to buy a scientific calculator with an attached Ewriter. It's can't retain notes on the display, but it functions well enough as an on-hand digital scratch paper. Still remains to be seen how useful it will end up being.
Great, many thanks, Sir! Have another book from that series: EM 324 „Elements of the Differential and Integral Calculus“, Feb. 1944, War Department Educational Manual, by Granville, Smith and Longley, 556 pages. It’s awesome and very challenging, going way beyond math capabilities of today’s students. Love it.
where do you find these random books? Online shopping, or in-person thrifting, or used book stores? Old reference books are a lot nicer than pdfs acquired online (or $100 limited-access pdfs, thanks Pearson).

The first hundred pages or so of "Machinery's Handbook" by Industrial Press is mathematics.

I use some of the book on a daily basis it's nice to see this on here

When we arrived at the trigonometry pages, I could smell them too.
Haha
Shop Math saved my life. It's true story.

Nice. How come they don't teach this any more?
I wish I could smell it lol
Are you nigerian ?
Are you intelligent?
