Doctorate in mathematics, specializing in probability theory, from the University of Georgia. Masters in AI from the University of Georgia. 15 years as a computer science professor at Texas Tech. Now I work as a logician for an AI startup. Married with one son. He's an awesome little dude.
I identify as an Evangelical Christian, but many Evangelicals would say that I am a deist mystic, and that I am going to Hell. Spiritually, the difference between me and Jordan Peterson is that I believe in miracles. The difference between me and Thomas Paine (an actual deist mystic) is that I believe the Bible is a message to us from the Holy Spirit, and the difference between me and Billy Graham is that I think there is noise in the signal.

This is simply not correct to say about the Law of Gravity. It is almost correct to say about the second law of motion:
F = MA
with one caveat. Newton implicitly assumes that each particle has a property, called its mass, which is constant over time. It turns out this not true: the mass of a particle can vary over time as a function of the object's velocity, according to the special theory of relativity. If you alter Newton's theory to make mass, force, and acceleration functions of time, then I think you are correct and the second law of motion is just the definition of mass. But then, by itself, it does not predict anything (since you could measure the mass of a particle, then perform an experiment, and anything could happen since the mass might have changed between weighing the particle and doing the experiment).
