Delta Prime's latest activity
-
Delta Prime reacted to vanhees71's post in the thread I Measurements and uncertainty principle with
Like.
In many but not all books. The collapse postulate is the most confusing of all the Copenhagen like interpretation schemes. Fortunately... -
I think you've missed the point of the thought experiment.

Delta Prime reacted to nsaspook's post in the thread When 50,000 volts go through a wire at 5,000,000 FPS - The Slow Mo Guy with Like.

Delta Prime reacted to Baluncore's post in the thread Ground loop on electronic audio systems with Like.
There should also be a capacitor between E1 and E2.

Delta Prime reacted to Baluncore's post in the thread Ground loop on electronic audio systems with Like.
Yes, you can, if you place values on all the components. Notice that there is actually no L1 in a coaxial cable. The transmission line...

Delta Prime reacted to Baluncore's post in the thread Ground loop on electronic audio systems with Like.
This was not a true hum loop, but was a more worrying situation. I noticed a "hot to the touch" power cable on a newly installed faulty...

Delta Prime reacted to PeroK's post in the thread B Energy-time uncertainty relation for a volume and macroscopic objects? with Like.
It's nothing like that. Time is not an observable in QM; it's an independent variable, unrelated to the particle itself (unlike the...

Delta Prime reacted to otennert's post in the thread B Energy-time uncertainty relation for a volume and macroscopic objects? with
Informative.
I think we have covered the "time-energy uncertainty relation" a couple of times already, see e.g. here... -
Delta Prime reacted to tech99's post in the thread Electromagnetic fields are polarised when leaving a dipole antenna.... with Like.
No. The radiation fields from a dipole and a loop are the same once we get further than about a sixth of a wavelength from the antenna...
-
Delta Prime reacted to kuruman's post in the thread Electric field of a finite linear distribution of charge with Like.
If integration is inevitable, then, since the electric field is zero at the origin by symmetry, the integral to do is $$V(x,y)=k\lambda...

Delta Prime reacted to BvU's post in the thread Coulomb's law to find electric field for charge density function with Like.
Coulomb's law ? ##\ ##

A couple of cows were smoking a joint and playing cards. That's right. The steaks were pretty high.
-
No. The photo is real. (Yes, I posted a very bad copy of it) It was made as a joke and posted in here as a joke...

The crazy thing today, the better it looks, the more likely it is to be a fake (AI generated).
