Engineers think that in the equation L = r x p, they can conserve in magnitude, both the angular momentum and the regular momentum simultaneously while r changes.

I told you this before but you didn't listen. Stop being a retard and listen this time.

You are right. In something like a tetherball wrapping around pole, kinetic energy is conserved and angular momentum is not. This is standard physics, it is not revolutionary.

In the ball on a string demonstration where a professor has to actually pull on the string to reduce the radius, the professor is putting in energy into the system. In this system energy is not conserved, but angular momentum is approximately conserved if the string stays rotating around the center and the speeds are low enough that you can ignore air resistance and friction.

>In something like a tetherball wrapping around pole, kinetic energy is conserved and angular momentum is not.
I wanted to contradict that but I worked it out and it turns out to be true. When a string wraps around a pole, the center of rotation is not in the center of the pole but at the point where the string is tangent to the pole and since the force on the weight comes only form the tension of the string the force is always perpendicular to the velocity of the weight, meaning that the energy is always constant here.
I'd like to add that while it is true that the angular momentum of the rotating weight isn't conserved, that is because it is exchanging angular momentum with the environment the pole is fixed to.

wtf

what drives /sci/entists to argue a topic they clearly have no idea about? I mean it's okay talking about a subject as a layman or interested person and having boundaries on the subject knowledge is natural, but pretending to be an expert, making wild claims, denying the status quo while simultaneously refusing to read the basics on the subject, and all of that with unmitigated confidence while being called out for their ignorance... what is there to gain being a pseud, especially here? why can't you guys just learn the basics?

James Webb Telescope discovered a much higher number of mature galaxies in the early universe than models would have predicted.

What is the official /sci/ explanation for this? Are our estimations for the age of the universe wrong? Perhaps just galactic formation occurs differently?

We could go back to statistics if you like.
Attached is a tuner used for HAM radio, called a PI filter or Twin-T filter (both different but the analogy is the same).
If I wanted to match impedance between 50 ohms and 75 ohms, how many possible combinations are there using the three dials?
Answer is: The number of solutions approaches infinity.
By controlling only three discrete variables, we are able to arrive at a nearly infinite number of possible solutions (within certain boundaries).

Applying multiple Fourier-derived filters can likewise lead to similarly astronomically diverse results. Or am I wrong?

>Applying multiple Fourier-derived filters can likewise lead to similarly astronomically diverse results. Or am I wrong?
There are infinitely many numbers between 0 and 1, it doesn't mean it encompass every number. Same goes for GW templates, they can't fit any data. If they could there would be false detections constantly in the time-slides.

And I misread the section of the generic burst search, it does not use templates at all as I originally thought. So double no.

Do any of you actually use this "trick" to help you understand a math/physics concept? I always found it useless and more confusing than helpful. Every professor, textbook, and online source always fails to reach me with this mnemonic, mainly because I don't get the relation between the direction of my fingers and the direction of my thumb. They never explain it and make it seem like obvious fact and it pisses me off.

I'm in Math, and when I asked a Physics PhD from the uni what are the requisites to get in to a Graduate Physics degree, he gave me book recommendations about the topics and he said basically being able to solve exercises from the first one or two chapters on each would get your foot in any further topic. That's effort for a month if taken like a summer course. But my career has some overlap with Physics, in fact the first two years are exactly the same here. I have a hard time figuring that doing the same with mechanical engineering would be any harder. But for your career sure, Electromagnetism hits harder and Physicists here only see so much circuitry and materials related to it.

In a difficult paper a reference can serve as a shorthand for a whole idea that is not explained properly in the present paper so you should be constantly flipping back and forth to see what the numbers stand for. If you haven't read many of the references before and can't understand the paper, back up and read a key paper from those first. You might have to jump around to several papers before the paper you are interested in makes sense.

I feel like if you were a scientist 100 years ago, there was a good chance that your work would significantly improve humanity.
Now, everything seems so piecemeal. Like you can only chip away at some subject so obscure that it is irrelevant to people, or only contribute a tiny amount to some meaningful effort.

I would love if someone could tell me "no, you aren't considering x field".
