Like.
A human being (and other life) grows by cell division. Your question would be what stops an entire human being spontaneously cloning... -

Informative.
Yes, decoherence. Macroscopic objects have many degrees of freedom, which interact with many degrees of freedom from the environment, so... -

I appreciate the feedback and I will do some more reading from the tips you have all given. Thanks for the patience shown to a novice

FactChecker reacted to JimWhoKnew's post in the thread High School Looking for an English translation of Levi-Civita's 1926 paper "Sur l'écart géodésique" ("On the geodesic deviation") with Like.
I don't know what is the right sub-form for this question, so I post it here. I'm looking for an English translation of Levi-Civita's...

FactChecker replied to the thread Undergrad Does Spacetime rotate like a vortex?.Spacetime is a coordinate system by which positions, velocities, accelerations, etc., can be measured. Some interesting and, IMO, fun...

FactChecker replied to the thread Undergrad On the Quantum Nature of EM Waves.It might be better to say that parts of the wave, each part coming through an associated slit and spreading as a simple sphere...

FactChecker reacted to PeterDonis's post in the thread Undergrad On the Quantum Nature of EM Waves with Informative.
In the case where you're running the experiment one quantum at a time (because the source is at sufficiently low intensity), each...

FactChecker reacted to PeterDonis's post in the thread Undergrad On the Quantum Nature of EM Waves with Informative.
No. If you're using QM--and really the path integral version of QM--in this way, you're not talking about EM waves any more. You're...

FactChecker reacted to Sagittarius A-Star's post in the thread High School Confusion about one of Maxwell's equations with Like.
Yes. But ##\Phi_B = \int \int_\Sigma {\vec B \cdot d\vec S}## changes over time, because the angle between the magnetic field and the...

FactChecker reacted to DaveE's post in the thread Undergrad Odd coincidence: two people with same name living on the same street with Like.
I suspect people named Kowalski are more common in the Chicago area than near San Diego, for example. Of course if it's just a math...

FactChecker replied to the thread High School Confusion about one of Maxwell's equations.This is about the amount of magnetic flux going through the open loop of the rotating wire. That is changing as the wire rotates. With...

FactChecker reacted to PeterDonis's post in the thread Graduate How valid is the Block Universe theory? with Like.
@DarkloidNeos the article you reference, unfortunately, is not just presenting the speculations or opinions of various physicists it...
