“We” who?
Just wait until the woke crowd m*****bates on Newton’s laws.
Their stupidity knows no bounds.
The “we” in the article refers to those to whom this level of semantic parsing matters.
Regarding this law though: what about a magnetically suspended top, spinning in a vacuum? Are there still forces acting upon it to slow it down?
Questions like this keep me awake at night...
Yup—human stupidity is endless, eternal, timeless—and obeys no laws.
“If we take the prevailing translation, of objects traveling in straight lines until a force compels them otherwise, then it raises the question: why would Newton write a law about bodies free of external forces when there is no such thing in our Universe; when gravity and friction are ever-present?”
The author’s argument makes no sense. Newton was talking about what happened to an object in the absence of external forces. Which makes perfect sense if the rest of your laws of motion then define how forces affect an object.
Of course, relativity turns Newton’s fixed frame of reference all topsy turvy.
Wouldn’t it depend on the torque in the magnetic field?
Take Benadryl.
Newton was racis?
Regarding this law though: what about a magnetically suspended top, spinning in a vacuum? Are there still forces acting upon it to slow it down?
= = =
Magnetic forces are suspending it.
And probably will result in slowing it.
And if you can really get a vacuum.
Einstein never meant to overturn Newton’s Laws. He just confirmed that they are appropriate and valid until about he 10th of the speed of light, and then they ‘kind of’ get a little goofy (in scientific terms).
“The whole point of the first law is to infer the existence of the force,”
This is what passes for grammar in science these days. People who don’t know the difference between “to infer” and “to imply”. You infer from the first law the existence of force, but the first law implies the existence of force. I think DEI is at work here. It is on the order of the guy who said the Odyssey was not written by Homer, but by a Greek with the same name.
Uh, yeah, we know this already, like forever.
Physics doesn’t change based on, “I don’t like it, so…”.
The hundreds of years of validation of what we currently know are a little bit relevant. Ping me in 4024 for a recap.
A distinction without a difference.
Yes, multiple ‘Homers’ just like multiple ‘Shakespeares’.........
“...It’s a description that works well until you appreciate external forces are constantly at work...”
Uhh, it’s a theoretical starting point for understanding physics and external forces are of course appreciated. Done in lab setting. Like a feather and bowling ball falling in a vacuum.
and the original translation says Priests will celebrate, not celebate...
oh dear.
Gravity is EVERWHERE.
Even in the depths of ‘intergalactic space’ there is gravity.
In order to eliminate gravity you would have to leave this Universe. But even then you would take some gravity with you.
If there was a universe that had only two hydrogen atoms in it, separated by billions of light years, there would still be ‘gravity’.........................
