I bought a cheap tablet for 35 AUD from officeworks. The normal price was 45 AUD but this device was pink (for kids) and had been returned. I took it home, and when I experimented with the gallery I found selfies taken by a child. I ran the factory reset but the pictures were still there so I just deleted the photos.

Actually I would argue that when we say that part of the Earth (like the ocean) is flat, we mean that it follows the shape of the WGS84 oblate spheroid, whereas an area the size of Kansas which was geometrically flat would look to us like a bowl, with its centre lower in gravitational terms than its perimeter.

The falcon can't throttle down enough to hover before landing so it has to approach the pad at high speed, and high acceleration. While doing this it has to rotate the entire vehicle to control lateral movement. It has to coordinate lateral and vertical acceleration to achieve near zero in all three axes at touchdown, with only one chance to get it right.

I doubt this can be done without extra thrusters for fine control over velocity and position.

We have a equal opportunity Calculus class -- it's fully integrated.
