„Immer habe ich nach dem Grundsatz gehandelt:
Lieber Geld verlieren als Vertrauen.
Die Unantastbarkeit meiner Versprechungen, der Glaube an den Wert meiner Ware und
an mein Wort standen mir stets höher als ein vorübergehender Gewinn. “

The Equation in solving these equation are exactly similiar in solving the electric Equation. It is still the same 'Maxwell' guy. We have in germany the term:
> "Strom,", "Wärmestrom", "Lichtstrom", "Volumenstrom", "Massestrom"
There is a voltage and resistance in each of them. (+ Historical transferable)
Also transferable by Logics (Work done in institutes and interested people)

After Whirl Wind (Supercomputer for the Aerospace) one of the engineers coined the word "Computer Aided Design". Hence, from the inventions of the Graphical User Interfaces, Simulation programs and early programs for Supercomputers, CAD programs were developed.

Bewegungen und "Ströme"
Bewegungen und "Ströme"
Aus der Geschichte vom 17 Jh. zur 19.Jh Industrialisierung bis heute wurden Ströme analysiert.
Besonders nach dem 2.Weltkrieg kann anhand der Publikationen der Nature-Autoren (Wissenschaftler), der Fortschritt von den ersten Forschungen von Curie mit radioaktiven Materialien (19Jh.), dann der Projekte in Los Alamos um Neutron Diffusionen (Manchester Projekt im Bau der Atombombe, 1945er) bis heute zu den Softwaresimulationen von Navier- Stokes Gleichungen abgeleitet werden.
Von Newtons Gleichungen im 16. Jh, wurde also in Richtung von FEM Simulatoren (20Jh.) bis heute zu moderneren Polygonen in der Grafikentwicklung oder Monte Carlo Simulationen (21Jh.) neue Simulationsmöglichkeiten von festen Zuständen.(zu biegsamen) zu flüssigen (von hart viskosen- rigiden zu weich viskosen) bis zu Gasgleichungen weiterentwickelt. Besonders die Physik mit der Richtung zu subatomaren Partikeln oder die Technik in der Suche nach leichten und robusten Materialien (oder formgedächtnissen), führte zu neueren Anwendungsmöglichkeiten für die Mechanik. Nicht nur die Glasproduktion von Fraunhofer, sondern auch das einfache Schweißen und Gießen von der Strahlproduktion in der Industrialisieurng ermöglichte neue Produktionsarten (Annealing). Auch folgend bspw. der Stahlbeton in Häusern. Und nun wird mit dem Blick zum Fliegen (anstelle Aluminium, Carbon, da es leichter und robuster ist) bis heute mit dem Blick zu den Sternen, höhere Temperaturen, neue Beschichtungen (sowie aggressiven Kühlen von Raketenengines) und neue Strukturen (AI- Naturähnliche Strukturen oder Adaption der Natur) erforscht.

Prequel: Mechanical Computer
Prequel: Mechanical Computer
Since the first Computers were obviously derived from mechanical machines, I'd like to spoil that.
Many may know the Babbage Story with Lovelace (First Coder), which was the inspiration for Vannevar Bush, an electro-mechanical Differential Analyzer.. Computer (Guy, who started DARPA and many more).
# Mechanical Computer:
But do you know things before that?
Computers are conceived to be complex, but it originated from a fcking calculator (Abacus 2700 B.C.).
It just stores information in these little stones. ('Calculus' ... Calc... from little stone pebbles in the name.) (Furthermore, they were sealed in a container, so to calculate the number of sheep on a field. then send the sealed container to the other person, so he can calculate how many sheep are out there. => Precursor of the paper money)
••• + •••• = ...(transported) ... •••• •••
If you carry your keys in one spiral ring, then you store another in each key ring another key. These were used in the ancient Babylonian as a counting devices. A Calculator.
Notable: The chess turk (automated chess player) originated there as well late 18 centuary, which was a fake device :)
Don't get cheated, when someone tries to perceive to understand a computer. They might cannot fix your printer, even if they write 'Code Lines', like other commoners, who can write letters in lines.
Enjoy!
Made of 400 parts, where it could lift it wings or had an own digestion system, like the real duck.
> Movement of an 'automated' robots. - a duck.
He had at first the idea of letting a machine create mathematical table! (like excel, But couldn't make it)
# Mechanical Computer Successor:
From the Antikythera (200 B.C.) to both mathematicians - Pascal's ' Pascaline' and Leibniz's' 'Step Reckoner' (18centuary) -, there has been also a mechanical -automated duck in the rural streets. (Jacques_de_Vaucanson)
He also automated the looms in France, which someone could calculate as well.
This also led to the famous story about Babbage and Lovelace, where even Lovelace insisted & begged, that Babbage shouldn't mess around with her programming device.
Remember that, when a teacher or prof tries to be 'smart'.
Notable: The finer the little calculus stones, or the wheels, the finer is your 'ruler'.
So you have a finer precision, if you have finer steps in the ruler.
More Transistors -> Finer Calculation of the Ruler. -> The Motor itself must achieve this precision as well. You can also draw an sqrt(2), as one number or you might have learned in Pythagoras, that you can half more precise with circles than the machine. So you can divide or draw/perform mathematically more precisely than the ruler. (with your math. language)
Already in the 19 century, Lord Kelvin used his analog computer to calculate the waves.
With exactly these thoughts in his head, he combined more pulley, as an addition. (Thanks to a friend, who told & helped him)
