What? Essentially every single piece of modern technology, including modern medicine, was developed by the Germans. Chemistry is all literally German, if you had any scientific literacy. Germans are largely still the only ones conducting blue sky chemistry research.
But yes, also alot was developed in America. One of the greatest founders of modern chemistry, Gibbs, was American. But these were developed by.... fellow Germanic immigrants. Gibbs was Germanic white. Modern science and technology is almost entirely Germanic/Nordic.
The foundations for quantum physics were founded in Germany. Einstein developed his theories in Germany (which were developed on the back of Planck's work - a German) though he had some jewish DNA.
"Darkest time in history" was spearheading the 2nd enlightenment? Okay. Dark for jewish subversives keeping Europe and the world down maybe. They liberated Europe to the best of their ability. Germans won Europe in the end - the EU (Germany dominated) is the effective third Reich and unification of Europe under German leadership.
Sir this a thread about groceries.
