- This book is filled with tons of applied mathematics. Most people never see all of this math. This is a cool book! It is titled Handbook of Applied Mathematics and it was written by Jansson.

Thank you:)
The poem in the beginning is in Swedish. The title is "the winterevening of an unemployed". It seems to be about a homeless person begging for money, and the person walking past him listens to his prayer and giving him a bit of help.
During WWII, General Omar Bradley was known for doing integral calculus in his tent at night to keep his mind sharp.
Source?
As a retired Professor of Mechanical Engineering, I would say this book is designed for people who use their hands and build things. In effect, it is a practical engineering textbook.
Growing up in the 1950's my father had several books very similar to this one. Unfortunately, students today do not use their hands and practical mathematics book such as these have gone out vogue.
I think I learned more from these books than many of the more theoretical books I encountered getting my various degrees. The knowledge from these books has been very useful to me over my 50+ year career and never led me astray (The language as others have already stated is Swedish.)
the language of the poem at the beginning is Swedish
What does it say?
Thank you, I thought the language was German. However, something seemed to be weird (to be German). Then I was betting It could be a Nordic language (still close to German). Finally, I got the answer by reading your comment.
@@saurabhsuman7417"The unemployed's winter evening."
@@paulopanarella1839 German for example doesn't has those circles above some vocals
@@LeoX2 what does the poem say?
The existence of this book (and modern versions that I have seen) proves that the supposed separation between "book knowledge" versus "practical knowledge" is a false one.
As other comments have already noted, the language of the paper insert is Swedish. Both the name of the book's previous owner (Johan Erikson) and of the author (Martin E. Jansson) are also Swedish names.
The paper insert contains a poem with the (loosely translated) title "Winter night of the Unemployed". Perhaps a striking reflection of the prevailing socioeconomic conditions in 1934?
Edit: my mother tongue is Swedish :)
There's a PDF file of it in the Internet Archive.
Can't smell it though...
@@tudogeo7061 True.
Popular Science and Popular Mechanics were monthly magazines that are still going strong
"The user is likely looking for information about the poem "Den arbetslöses vinterkväll" written by A. F. Edin, which translates to "The Unemployed's Winter Evening" in English. This poem was published in 1925 in Sweden."
Nice!
ChatGPT? Lol
Like so much old Scandinavian literature, it is about the poor peoples struggle in the wintertime, and how they are ignored by the rich, which is especially heartbreaking in the cold climate of Sweden. Most famous example is The Little Match Girl.
oh didn't see the backside, it sais there are people who will help him because they are reminded that they also count on their neighbours help from time to time and something about the Lord
A different kind of concrete mathematics (to the Knuth book) lol
I workeed as a construction estimator and planner/scheduler for some 13 years and I would have given mt eye teeth for a book such as this!
Mr Sorcerer,You definitely need to buy yourself a copy of The Machinery Handbook ! The older ones come with a green leather binding with thumb nail indents in the wall of the book for easy indexing. Its a VERY detailed book on science/engineering/maths !
Swedish: the beginning is
"An unemployed person, clearly disappointed with life, stands in the winter twilight this evening. Do not pass by in haste, but listen to his plea at the door, so that he does not remain under the cold snow. The small help you give from your hand makes him happy, and he will be so grateful to you. And the Lord will give you the reward on Judgment Day."
Your videos really help keep me motivated and interested. I am currently taking a break from my Discrete Math HW to watch this!
Always gotta smell the old books first !
Maybe it's a text that was used mainly in trade schools, which I think used to be more popular educational alternatives than they are now,
unfortunately.
I am sure the guy in the 60's put that shop guide in his book thinking to himself, "One day, some guy is going to need to smell this."
Can you make a video about applied math major vs pure math major? I can't choose.
Not quite German, but almost. Maybe Danish?
"Lathing" is pronounced with a long A, like "bathing".
And "legerdemain" is an old Frenchism meaning "slight of hand".
They probably teach some of this in one form or another in Vocational School.
It is not German. You have the å letter, it is either Swedish or Norwegian.
From what I've read there was at some point a transition from teaching this style to more abstraction base methods.
Fascinating. Today applied mathematics usually means numerical math to solve some math problems.
Here applied is really applied. For real. In the real world.
I hope that smell is not mold. I have an old book that has a moldy smell. As an old book collector, do you (or anyone else) have any good tips on getting the mold smell out of an old book? Thanks.
Scandinavian, Swedish I believe.
Great Video 👍
This is not a strange book at all. It is a standard book for mechanical engineers when they need to calculate the geometry of gears in a gearbox for example. So not a book on math at all. i have tons of books on these topics.
what is strange about this? looks like typical engineering things
Its swedish
I personally would not be worrying too much about "mysterious stains"😅
Give it to chatgpt and have it translated
Love ur vids!
Any books recommended to self study for all of electrical engineering from basic to advanced?
This type of books were used by students of arts and crafts schools.
Cool!
The whole book is available on the Internet Archive. You're welcome.
The page at the start is swedish.
The name looks like Johan Eric Erickson. The language looks likely to be Swedish.
How can I write a book about something? I have a lot of in many topics such as language learning, math, physics, programming, cybersecurity, philosophy, chemistry, and others that I can't recall. I love them and I want to have something like a master's degree or PhD but unfortunately I am still young and I don't know where to start.
Start by getting the degrees. Keep working on your things in side. Your views will change, and mature
@Oliver_without_a_twist I am still a high school student and I don't know how to start especially since my family cannot afford it and I don't know which university in which country will accept me.
Really nice subjects
Amazing !!
i cant get in my country :(
Legerdemain is ‘sleight of hand’.
SLIGHT of hand NOT sleight ... !!
@@irenehartlmayr8369 slight means small or thin whereas sleight means clever or cunning.
@@bigm383 Yes, but " leger de main " means slight,in the sense of being not heavy ! So it means "slight of hand "...i.e. not heavy,easy.
Anyway,thanks.
Sleight seems to be a new word to me....! Didn't hear that before....
@@irenehartlmayr8369 So you disagree with the Cambridge English Dictionary?
@@bigm383 I didn't look it up there.But leger de main is French and the meaning in French is what I wrote.... there are variations in interpretation when transposed into another language and used there....!
I like it
😮
It’s not German.
Never seen before math, what a load of crap
me like math
Digital books are superior to real books in one way, they do not require bookshelves. The drawback to then is that if your CPU fails, you could well lose your entire library.
I found this book on Amazon and they asking ten dollars for it.
Applied mathematics is pretty familiar among Indian students because every government exams ask applied math question
I was about to say either Norwegian or Swedish. It is Swedish. Thanks people in the comments!
Dutch
.... zeker niet. Zweeds.
It’s Swedish. Not Dutch.
The mysterious paper is indded german and the title translates to "The winter of (un)employment"
It's Swedish. The text is close enough to German for some/much of it to be read but it's definitely not German.
1:00 It's Swedish :) Not German, but related.
