Figure 4.2: Really, mate? Never had an insect flying in a moving car?
Figure 1.2 - I like that one. It's a perfect argument for the round, rotating and revolving Earth with the stars being far away - orders of magnitude farther than the Earth travel distances during the 24h cycle (so the startrail shapes are not really affected). At the same time, the perfectly circular shape of the star trails disprove the FE model with the stars fixed on the rotating literal, hemispherical firmament - the trails would be circular only if observed from the vicinity of the North Pole. From any other spot they'd track an oval (more elongated the farther from the North Pole You are). Ever thought about it?
Also congrats for making it into a SciManDan youtube video ;)
