Engineering and science cheat sheets

The rule for this section is numbers with sources. The rocket comparison lists payload, thrust and reuse for Starship, New Glenn, Falcon Heavy and the rest. The humanoid robot page compares the announced robots by height, payload, battery and actuators. Starlink, Tesla and Boom Overture get spec sheets rather than press coverage.

The data center cluster is the largest: how power gets from the grid to the GPU, when air cooling stops working, the order-of-magnitude numbers everyone in the industry should know, and a page that grades the claims made when a data center is proposed for your town. Semiconductor manufacturing walks wafer to chip. Nuclear reactor types, deaths per terawatt-hour and geoengineering cover energy and climate with the same discipline.

Engineering metals, materials and the sensor comparison are for the person choosing a part. Human evolution and the stellar lifecycle are here because they were fun to build.
