True! I'm interested in all kinds of physics, but what I love the most is going deep on a topic and then returning to everyday life and seeing everything differently. I spent a couple of weeks on an almost altered state of consciousness after my first time learning about relativity. I always...
As a hobbyist, studying physics is deeply pleasurable. Yet, I never seem to find anyone discussing this? Discussions on the merits of learning physics always focus on its practical utilites. Are you aware of any books or articles where physicists discuss the deep pleasures that come from...
Of course, makes perfect sense.
But what if I'm trying to setup this same problem from the start from the reference frame of the male clock? Would I be wrong in drawing a spacetime diagram where the female clock's worldline starts at ##x' = 2d##, the midpoint's worldline starts at ##x' = d##...
Follow-up question: when setting up the problem from the male clock's frame, I'd expect the midway point to move towards the male clock with speed ##v##, and the female clock to move towards the male clock with speed ##2v##. However, since ##D1## and ##D2## are different (##D2 > D1##) at all...
I followed this suggestion and obtained the expected result. Thanks for the suggestions. I will now try to do the same using the Lorentz transformations.
This is not a homework question, just a scenario I've come up with. Imagine I have a male and a female clock moving towards each other. If they're in sync, one will fit inside the other and they'll continue on their way. If not, they'll collide. (Apologies for the crude drawings.)
I place these...
I'm reading a book about electrocardiograms. In one page, the author says that when a wave of depolarization (positively charged sodium ions enter the muscle cells of the heart, causing contraction) moves through the heart toward an electrode placed on the skin, an upward deflection is...
Thanks a lot for the feedback, phinds!
I'll just ascribe that idea to the "fiction" part of "science fiction". After all, scientific knowledge is always "as far as we know". :)
Hey, guys. I'm writing a science fiction novel and would like to know if you guys think there's anything wrong with the grammar in this sentence:
"Space-time tunnels required large amounts of dark matter to stay open, and they could not be closed during the course of the mission, for it took...
Thanks for taking the time to write all of this. I'm aware of everything you said.
However, the question being asked here is really pretty simple: due to the rotation of the Earth, objects lying still on the planet's surface are always describing curved trajectories. For an object to describe...
