What exactly is tunnel splitting? The essay mentions this various times without clearly explaining what it is, and whenever I search it up online multiple things are said about it.

From what I could understand, quantum spin tunnel splitting makes it so that the magnetization of a system can "switch between states with opposite magnetization that are separated by an energy barrier much larger than thermal energy". But what exactly happens during tunnel splitting? And why are there different ones mentioned in the article? [magnetization tunneling, zero-field tunnel splitting, ground-state tunnel splitting]

I also understand that this phenomenon "defies classical physics" because of magnetization switching. How is that possible?

This is a learning objective.

The light is reflected back inside the water, because of the total internal reflection:

• water is denser than air
• angle of incidence is greater than the so-called critical angle

Wet things become darker, because of the water consistency, reflectance that doesn't let all the light to transmit through it.

The probability of light getting transmitted is: 1 - R1 (reflectance at the air-liquid interface)

Two types of reflection:

1. specular - light leaves the surface at the same angle it hits it
2. diffuse - hitting light is scattered into all angles when reflected

It is definitely NOT 100%. However, it is safe to say "... is very close to 100% ..." or " .... is nearly 100% ..."

"... were required to be robust against the high-multiplicity environment..."

"Lead ion nuclei" is a little redundant. Stick to just "Lead ions" or "Lead nuclei".

"B" is usually reserved for the meson states of the b-quark. Since this is general, including potential baryonic states, I believe this should be "b-hadron".

We're not removing overlapping regions, right? Rather, we are merging overlapping ROIs into one single ROI so as to incorporate the reality that they overlap. The image illustrates that, and not a removal of the intersection of two ROIs (which is what this language implies).

"selected" or "produced"? Not sure what the intent is here for the underlying verb. ROIs would normally result (be produced) from the L1 trigger, then be used in the HLT. So is "produced" the right word?

This is needed.

MV2 doesn't use the output of SV1; it uses inputs employed by SV1 to make decisions, but makes them instead using the BDT architecture.

提出了 AI Physicist 这样的概念（paradigm），这也算是我的某种终极目标吧。

只能说是有趣吧，对理论的归纳和理解也比较有趣。

It seems that the author is establishing a relationship between modern physics and technology as a circular relationship in that modern physics would not be possible if technology did not allow us to study it nor would technology advance should modern physics not be studied. So, essentially, modern technology is a method to reveal modern physics to us? Therefore, modern technology is also a revealing just as modern physics is a revealing, but that they mutually allow each other to do so?

Some interesting data points in this article.

How widely known is this figure?

A new theory of the relationship of mind and matter, David Bohm

You have probably heard about the hunt for dark matter, a mysterious substance thought to permeate the universe, the effects of which we can see through its gravitational pull. But our models of the universe also say there should be about twice as much ordinary matter out there, compared with what we have observed so far.

Two separate teams found the missing matter – made of particles called baryons rather than dark matter – linking galaxies together through filaments of hot, diffuse gas.

It would be interesting to discuss these similarities. From my non-chemist brain, I see more pattern and regularity in the chemical than in the social. Reminds me of NDTyson quote that physics is easy and sociology is hard because of the nonlinearity of human behavior.

'The Nobel Prize in Physics 2013 was awarded jointly to François Englert and Peter W. Higgs "for the theoretical discovery of a mechanism that contributes to our understanding of the origin of mass of subatomic particles, and which recently was confirmed through the discovery of the predicted fundamental particle, by the ATLAS and CMS experiments at CERN's Large Hadron Collider"'

The term "decay" when applied to non-macro phenomena is terribly misleading for anyone who isn't a physicist.

"Decay" has several meanings (see the Wikipedia page), but it would not be foolish to assume that the term is commonly associated with things like decomposition or biological decays. Even in physics, an orbital decay is a gradual process.

"Transformation" is much more applicable, and is a term I've used myself over the last few years instead of "decay" in this context.

Look at "Four-vectors": https://en.wikipedia.org/wiki/Four-vector

Or is it that all particles that interact with the BEH field have mass? ;)

Typically, though, the matter particles (fermions) are grouped into two, depending on whether they interact with the colour charge (quarks) or not (leptons, which include both the electrically charged leptons and neutrinos).

However, the division into three groups, as shown here, is helpful!

Wow, this is a specialty!

That is, π^2/90 = 2π * π/180 to convert 2π to degrees.

Page 187 On hyper authorship

"hyper authorship” is an indicator of "collective cognition" in which the specific contributions of individuals no longer can be identified. Physics has among the highest rates of coauthorship in the sciences and the highest rates of self archiving documents via a repository. Whether the relationship between research collaborators (as indicated by the rates of coauthorship) and sharing publications (as reflected in self archiving) holds in other fields is a question worth exploring empirically.

Straightforward intuition isn't just intuition.

Doesn't give reference on how the physicist detector models are known in wikipedia

Physicists authorship models

biomedicine is a less homogeneous group and so less internal trust

physicists live in a very trustful, observant, world; also they do a lot of internal, pre-referee, review

Why is there less soul-searching about hyper-authorship in HEP? disciplinary differences

Multiple authorship is not problematised in the HEP community as it has in biomedicine.

Great overview of what is going to happen in article:

1. History of authorship
2. Survey of state of biomedicine
3. "extent to which deviant publishing practices in biomedical publishing are a function of sociocognitive and structural characteris-tics of the discipline by comparing biomedicine with high energy physics, the only other field which appears to exhibit comparable hyperauthorship tendencies"
4. Assess extent to which biomedical trends may foreshadow trends in other fields.

The researchers describe their experiment as a “loophole-free Bell test” in a reference to an experiment proposed in 1964 by the physicist John Stewart Bell as a way of proving that “spooky action at a distance” is real.

Really interesting abstract.
