Während die faschos in der Öffentlichkeit über ethnische Säuberungen phantasieren, ist vielen Bürgerlichen sogar AfD Plakate abnehmen zu radikal, weil ja illegal. Da finde ich es ziemlich gut da so offen drüber zu reden, ohne plausible deniability, das normalisiert das ja auch irgendwie
Too much pillow talk?
...oh, they're talking about a shirt

But actually it should be Englischtest, in German compound nouns are used
I imagine most historical figures will be profoundly disappointed when they learn of modern politics... No god-emperors, no global communism, just a capitalist hellhole full of near-fascist governments. Mussolini might have a field day, but imagine summoning the ghost of Ramesses II or Vladimir Lenin into today's political landscape
You just discovered the field of calculus! If you look closely enough at any smooth function it looks locally linear, and the slope of that linear function is it's derivative
Not quite what's happening here, here the problem is if you consider geodesics on a sphere to be straight. In special geometry they are, for all intents and purposes, but in higher euclidian geometry they form large circles
You are absolutely correct, but to add on to that even more:
When we talk about space, we usually think about 3D euclidean space. That means that straight lines are the shortest way between two points, parallel lines stay the same distance forever, and a whole bunch of other nice features.
Another way of thinking about objects like the earth is to think of them as 2D spherical manifolds. That means we concern ourself only to the surface of the earth, with no concept of going below the surface or flying up into the sky. In S2 (that's what you call a 2D spherical manifold), and in spherical geometry in general, parallel straight lines will eventually cross, and further on loop back and form a closed loop. Sounds weird, right? Well, we do it all the time. Look at lines of Longitude, for example.
We call the shortest line connecting two points in curved manifolds geodesics, as you said, and for all intents and purposes, they are straight. Remember, there is no concept of leaving the sphere, these two coordinates is all there is.
What one can do, if one wants to, is embed any manifold into a higher-dimensional euclidean one. Geodesics in the embedded manifold are usually not straight in higher-dimensional euclidean space. Geodesics on a sphere, for example, look like great circles in 3D.
What if you're closer than five meters from what you've been old? /j
Even then, the difference between 20 and 2000 characters is negligible
