Working in manufacturing, I’ve seen that the norm is for engineers to fail to get it right the first time, or the second, or the third, etc. And if they do eventually get it right, it’s because they have present physically reality to give them a reality check.

Stupid mistake.

It just so happens:

* the Earth is an inertial referential (to a very good approximation)
* describing the movement in the center of mass frame is a lot simpler and the center of mass coincides to a very high degree with the Sun’s position due to the fact the fact it has a much higher inertial mass than the Earth.

deterministic = A always causes B, A causes only B, and only A causes B.

materialism = A and B are fixed, unchanging, measurable, physical objects that are representative of the contents of the entire universe, observed or not, including all human thought, throughout the entire past, present, and future.

Alternatively, A and B could be processes involving such objects. A physicist who believes in “heat,” “fire,” “energy,” “electromagnetic fields,” or “gravity” might compromise by proposing that some processes seem to be non-materialistic only because we haven’t found the magic particle yet that would explain them.

Just in case I wasn’t clear, I was not typecasting janitors. I used to be one, and they are usually smarter than you think. However, I also used to be a salesman, and they are usually dumber than you think.
