None actually , its just my phone camera which i stick up against my lens whenever i see something

Sigma sagittarii(uncropped(1) and cropped(2)) Antares(uncropped(1) and cropped(2)) These were the only images i could take as it is monsoon season so it gets cloudy really quickly so i took as many as i could within a few minutes.Enjoy!

Yes i was recommended this very book by users here, i have started it but not yet completed 👍

I do have a basic idea of flat spacetime and a curvature in that spacetime due to mass present causes gravitation (not a force when it comes to this i think ?)

I found that they are ripples in spacetime. I saw a image of two stars rotating and the ripples were labelled gravitational waves Oh and they also travel at the speed of light(a NASA site) and caused by supernova and such https://spaceplace.nasa.gov/gravitational-waves/en/

Many more questions....please enlighten me on this topic. thank you!

Oh okay ...but why do we not consider individual electrons while saying current is scalar or tensor? Is it based on frame of reference by any chance? If say i were to not consider current density(vector) and rather only current with 3 electrons flowing what would that be . Do i consider it a...

Electric field is present . The net movement of electrons would flow in direction opposite to the electric field yes.But if we were to take a small cross section of the conductor and say 3 electrons are moving in slightly different directions would that not mean that it has 3 components to the...

Oh ok 👍just another question that do we have anything better than einstein's SR and GR as of now ?

Oh .....now that makes so much more sense.

.

I understand , but what is causing the leaves going yellow?. Someone please explain it for me (and ofcourse the OP too) will be of great help thank you! Maybe this article can explain ? https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7411892/

Not my field of expertise but my suggestion is you might want to use conc.sulphuric acid to remove the waxy cuticle layer. The cuticle is made of polysaccharides also it might dehydrate the leaf too if it reaches the leaf layer( just a suggestion , i have no real experience but you might want to...

Maybe this can help you

I will answer your question but only the one here on PF. Electromotive force is basically the potential difference between two points before they are connected . Now there are two cases after connection is made between the points of 2 different potentials Case 1: EMF = Voltage This happens...
