📡Our 66 cosmic antennas, each weighing 100 tons, can be moved and connected to ground bases known as ‘pads'. ✨This flexibility allows the array to be arranged in different configurations, depending on what part of the cold Universe is being observed. 📷: Y. Villalón

Yes, it happens to be the case that the classic 'The Classical Theory of Fields' by Landau and Lifshitz is publicly available on the Internet Archive, and if I were you, I'd go and check it out.

Many people think the Apollo Lunar Module was a small, fragile craft — but this image puts its true scale into perspective. Standing over 7 meters tall and weighing more than 15 tons fully fueled, the Lunar Module was no toy. It was a two-stage spacecraft designed to land on the
