Reply to comment by Weed_O_Whirler in Light traveling through a medium that slows it. Does the same photon emerge? by TheGandPTurtle
A quality answer and even some better added mystery. Nice! Well done. So, why do physicists fight about that? Is it actually unsettled science?
Are there any other mysterious things in physics you can share?
My favorite thing I’ve been learning about lately (as a layman) is the double slit experiment, quantum mechanics, how particles behave differently when observed. I’ve been reading people say that one possible answer is the many worlds theory, and I haven’t heard other respected theories yet. Any thoughts?

Reply to comment by Current-Ad6521 in Why do dopamine reuptake inhibitors not treat Parkinson's disease? by unripenedboyparts
So, it is my understanding that Duadopa is supposed to be less likely to induce tardive dyskinesia than oral ingestion of Levadopa. Is this because it's pumped directly to the GI system? How would it have a positive effect on the lungs & heart that way? And is there a reason that tryptophan isn't used in the treatment of Parkinson's?

But the total spin of helium 4 is whole, which makes the whole system a boson

Big step up from basically anywhere else in the solar system other than earth though. And Iirc oxygen is buoyant enough in this atmosphere that you can live inside oxygen balloons which solves some logistic problems of building the cloud city.
Overall venus is a serious contender for off world colonisation when we get to that point along with mars and moon

Reply to comment by WhoAm_I_AmWho in Is it possible that abiogenesis is still happening right now on earth? by dolekanteel
This is what Nick Lane talks about in his books. Hydrothermal vents were very likely important in abiogenesis but only in an ocean with a different chemical makeup than today

Because photons aren’t traveling through a medium of photons. It’s a propagating electromagnetic field.

I believe you are referring to the one-electron universe postulate. https://en.wikipedia.org/wiki/One-electron_universe

Yes, there is a formula to calculate the proportion of water at different temperatures needed to obtain a desired temperature. The formula is known as the "weighted average temperature formula" and it can be expressed as:
(T1w1 + T2w2) / (w1 + w2) = T3
where T1 and T2 are the temperatures of the two water samples, w1 and w2 are their respective weights or amounts, and T3 is the desired temperature.
Using this formula, you can solve for the unknown weight or amount of each water sample needed to obtain the desired temperature.
This formula can also be applied to other fluids as long as their specific heat capacity and density are known.

Electrons are fermions and cannot occupy the same quantum state, hence why there is exchange energy. Photons are bosons and are able to occupy the same quantum state, so there is no exchange energy for photons. Hope this answers your question :) -another quantum chemist

I had no idea legionella was named after the outbreak among American legion members and that’s where the legionnaires name comes from. Wow

What if photons have tiny little “fingerprints” where you could, with sensitive enough equipment, identify them?
Or like a serial number…
Would that work for identifying them each and seeing if it was the same?

Thank you a lot for responding, however i want to know, what dose are you talking about when you say "dosage"?
