It was too revolutionary!

Seems @Vanadium 50 isn't the only one thinking about this: https://www.euronews.com/next/2023/09/12/scientists-believe-black-holes-are-lurking-much-closer-to-earth-than-we-previously-thought#:~:text=Data%20from%20the%20European%20Space,light%2Dyears%20from%20Earth%20respectively. My guess is...

1) The galaxy looks much more like a square than a cube. 2) the center of the galaxy has about 30 times the stellar density of the edge. Both of these together easily give two orders of magnitude.

I had typed out a long explanation but then realized it was far more math-based than your OP! The most intuitive explanation is probably that the Raman effect is a two-photon process. Since the EM field is represented by a vector, two-photon processes must be represented by a rank-2 tensor. We...

The answer is yes, most likely: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7906952/ The mechanism of action is still up in the air, as the chemical reactivity of PFAS itself is very low. However, physically, PFAS “looks” a lot like lipids, and can activate lipid-specific pathways and partition...

The equation you’re looking for is the Poisson Boltzmann equation: https://en.m.wikipedia.org/wiki/Poisson–Boltzmann_equation

I’m bored so let’s try some quick order of magnitude estimates. According to a quick google search, the biggest needle likely to be used for vaccination is a 22 gauge 1.5 inch. This has an inner diameter of about 0.4 mm, giving a total volume of about 4 cu mm. The Covid booster is 250 cu mm. So...

Science says nothing about meaning; if you're looking for it there, you've already gone astray. Forum activity across the board may be down, but also consider that it's summer and school has only recently started up (at least in the US). There always seems to be a dip in activity during the...

Roughly the last 10 years have also seen time crystals (AMO physics) and the thermodynamic uncertainty relation (stat mech) in theoretical physics, as well as room temperature exciton condensates and moire physics in twisted 2D materials (both condensed matter/solid state) in experimental...

You definitely don't need to assume a contradiction. Also, 2 is not a premise. 2 can be derived from the premise "ABC is a city with more than 5 million inhabitants" by using existential introduction: ##P(a)\vdash\exists x P(x)## but this is also not necessary in the proof.

A few things: 1. The form of your post is very difficult to follow. You have a 1, a 4, but no 2 or 3. You have things labeled as premises in very odd (and likely incorrect) ways. I would lay out everything a little more cleanly than this if I were you. 2. This looks like a homework problem. I'll...

Why would the methyl group have changed position upon reaction with bromine water? Edit: to be clear, you’re likely not going to get any stereochemical information out of these experiments. But you should still think about the question above as it relates to your OP.

It has nothing to do with the structure of glucose, as the two anomers of glucopyranose interconvert rapidly under physiological conditions. Instead, it has to do with the disruption of the pathway that's activated when insulin binds to cellular insulin receptors. In simple terms: glucose can't...

Here’s a video that just popped up in my YouTube feed where they explain PVT diagrams: There are some good animations in here that make it a little clearer what’s going on.

I’m not sure this is right. The -CH2OH group is not particularly activating to the phenyl ring. There is a far more strongly activating group that you should consider.
