I think the more interesting thing is that a moving object will keep moving at constant speed unless a force is applied to it.
Like, um, the friction against the ground that the object is moving on. Isaac Newton observed commonplace phenomena then figured out the scientific reasoning behind the phenomena then put it all into words that we now quote as time-tested & true scientific dogma.
Then Einstein comes in and says everything is moving at a constant spacetime velocity, and that friction isn’t a real force.
Friction is real, it’s the “force” of gravity that is an illusion.
True, like any good physicist, which I am not, I skipped the explanation of physics world. I was trying to be more funny than clever.
Einstein was a bit of a bad boy
Gravity, not friction!
It was his math contributions people liked. Particularly his invention of calculus which could be used to solve a plethora of unsolved math problems. It’s not because he said things fell.
Isaac Newton invented meth???

TBF, that’s actually a pretty profound insight.
Most, if not all, of us take certain concepts for granted until someone points out that it’s more complex than we realise. Examples like Dark Energy & Matter, entropy, the placebo effect, the nature of mathematical objects, etc. are proof of this.
It’s not unless. It’s until, which has more implications.
That’s not Newton’s contribution. Aristotle already said that an object only moves if a force acts upon it.
Gödel: “Using logic ive shown that there will always be true statements can not be proven/falsifiable within any formal system of logic”
Mathematicians:
Is that one as intuitive, though? I haven’t ever heard an intuitive explanation for it.
In fairness, at the time, many Europeans believed in faries and other creatures, including these guys:

So, not much has changed then…
Gibson said “The future is here, it’s just not evenly distributed.”
The future was there with Newton, but it’s still not evenly distributed 400 years later.
Touché!
“Your Grace, he has sinned against the church!”
If anything was going to get Newton in trouble with the Church, it would have been his lifelong obsession with alchemy, not his three laws.
This actually wasn’t obvious at all. If I let go of an apple in midair, it falls. Why? Nothing appeared to be acting on it. The “common sense” explanation is that things naturally fall. Their “default” action is to move toward the earth. That’s why there are explanations from ancient myths about the sun and stars being “hung” in the sky. Cause otherwise, they would fall to earth too, right? Everything does.
What Newton did was to show that there is a force acting on the apple, and without that force, it wouldn’t move. He also came up with an equation that could predict what that force would be between any two objects at any distance, and what motion or lack of motion would result from that force.
Can someone put this guy next to monkey Jesus?
Yeah, it really feels like every toddler figures this out for themselves. He just said it succinctly.
its like how the idea of putting one number in front of another for a tens or hundreds figure seems so obvious but took forever to invent
