I hope that it goes that way, and marketing it that way to A may help smooth the situation if there is any perceived risk of friction.

The combined answers of Moishe and Buffy cover all the bases of my thoughts for an answer. Co-authorship on a paper detailing both approaches, and why one is superior (and by how much). B learns about the problem itself from A, A learns about the new approach from B. A provides literature expertise and one method, B provides a solution and another method. In my mind this is a near-equal scientific exchange and a beautiful opportunity for everyone involved.

I think approaching DEI with a genuine desire for learning can be a good path forward. Surely your institution's DEI offers workshops or other training opportunities? You don't have to say anything. Attend with the goal of listening. You aren't committed yet. Go with an open ear and the goal of finding a way forward.

Ah I see what you mean now. Thank you for the more detailed explanation of your position. I hope your workplace isn't quite so hostile as to keep tabs on who might be a "problematic person".

Why would you do that then? And if you can't do that, surely you can inch toward an answer by learning more about DEI generally. I assume you have a good-faith reason for asking this question here, because if you didn't you wouldn't be so interested in finding a path forward, correct?

Surely a conversation starter such as "I'd like a better understanding of DEI and how it applies to me as an instructor, so I can give the best possible experience to students of all backgrounds." would do no harm, right?

When you asked your institution's DEI about your need for understanding, your struggle, and about your proposal here, what did they tell you?

I understand what you are saying. I still disagree with the need for the external opinions. Again, this isn't the right place for me to be making this argument, because it appears to be the site's expectation for high-quality questions of this type.

My thoughts are not about politics, but about question quality. I have reviewed the chat now, thank you. I still disagree with the need for the supporting opinions, and disagree with the need for them in the other question. The external opinions on that question are immaterial to the question itself, and to that OP's own opinion. They are similarly immaterial to this question. However, if external opinion pieces as fluffy background is the structure that makes for high quality questions on this sub-site, then my argument is being made in the wrong place.

@Dilworth Your fears could be easily allayed by removing the statement. It is, as you say in the post, immaterial to the question.

@Dilworth "Regardless of the arguments for or against DEI" Then why did you bring up those arguments? The question could be made clearer by removing the arguments.
wwarriner
Jan 13, 2022 18:09
The entire statement should be removed per my second comment as it is immaterial to the question posed by the OP, and by the OP's own admission. The statement only increases signal-to-noise, decreasing the quality of the question.
wwarriner
Jan 13, 2022 18:09
@Dilworth Are you aware of the weasel words (e.g. "some" academics) used in your post? The words are supported by scant evidence of the claims made in the context of those words, and the links give the impression of "some" meaning "one". To make the post clearer, please replace "some academics" with "one academic" and "some other groups" with "one group".

Additionally, the normalized shear stress of a pipe supported to IPC codes is absurdly low, probably near the bottom of the graph. To get the exponential line to swing way down to that low normalized shear stress at 0.2 HT would be 10^<some large negative number> per second. Given a decade is 10^8 seconds, we're talking noticeable creep rates in copper pipe on the order of millions or billions of years, probably. I'm guessing it would fully oxidize or sulfurize long before then, assuming your building were still standing.

The key here is the homologous temperature, i.e. material temperature divided by material melting point. For lead this is 0.5 at room temperature. For copper it is closer to 0.2. Vacancy movement, the primary cause of creep (to a first approximation) is an Arrhenius process, meaning creep is exponentially dependent on (homologous) temperature, as we see in the lovely diagrams above. This explains why lead creeps noticeably on the order of decades, but copper does not. A decade is 10^8 seconds for reference.

I recommend looking up Revolution over Advantage, as it prevents ticks and heartworms as well. At our vet it was about 15 per dose, each lasting 30 days.

Also cat fleas can jump up to thigh height on humans and can come indoors on clothing. Make sure to treat any other cats or dogs you might have. If the cat spends lots of time in your yard you may also have an outdoor infestation so it may be worth treating your yard as well. These things are incredibly persistent! One fertilized female is more than enough to set off an infestation, and it is a huge pain to eradicate. From experience, twice :/

If you take the cat to the vet, they have a medication called Capstar that kills 90% of fleas on the body in a few hours. You can watch the little jerks literally fall off dead. Its a bit pricey (20-30 USD per dose), but makes an excellent first-line attack on the flea problem.

... and a thin, flexible sheet would probably fare better than a plate. Think of a bullet-resistant vest. It's made from tightly-woven kevlar fibers that catch the bullet, rather than try to rigidly stop it like armor. If the kevlar were bound up in a rigid matrix, the bullet might just shear the whole material, fibers and all, and punch a hole through the entire thing.

@OneSurvivor I'd agree with Ville Niemi and add that it probably depends partly on a combination of strength and ductility of what's being impacted, at the appropriate strain rates. If the material is both strong and ductile, like steel, it will absorb a lot of energy and not deform much. If the material is only strong, like ceramic or glass, it will tend to shatter. If the material is only ductile, like many polymers, it will tend to deform out of the way of the bullet. I don't know enough about mantis shrimp material to know what will happen, unfortunately. It also depends on thickness...

Your best bet for a reasonably accurate answer, as is my understanding as a materials engineer, is to use an FEA simulation with realistic material properties and boundary conditions. There isn't really a one-shot answer for this kind of problem. If you watch this video on youtube it might give you an idea why the math isn't straightforward. Basically, the interactions aren't rigid and the bullets start acting like liquids due to the extreme speed of shape changes. My estimate comes from high-school physics using PE = mgh, and so forth.

Cool answer, I learned some stuff about mantis shrimps! I'd caution that high velocity impact behavior is not readily calculated using back-of-the-envelope type calculations, so the math may be misleading. That said, you could estimate using a static energy condition and an equivalent mass resting on the armor. I estimate the bullet mass, at a height of 0.1 in with all energy as gravitational potential energy, at 50kg, which exerts about ~500 kN on its tip only (~5% of the xsection), giving just under 400 MPa pressure.

Sounds like a great opportunity to learn new things, meet new people, make friends, inspire young people, do something good for the community, pad your resume, see new places, prove you are a team player, get kudos from your boss, and get paid for all of it. It's unfortunate that you don't want to travel.

What does "the best" mean to you? What do you think "the best" means to your advisor? To your other colleagues? To famous names in your field? I imagine any two people would define it quite differently. On a slightly different note, as Thomas Carlyle said: "Every [person] is my superior in that I may learn from [them]." And just as likely, by the time you are done with your PhD, people will be able to learn something about their own field from you. That makes you their superior! :) And if everyone can learn from you--you are superior to everyone--then aren't you the best?

"Is this a reasonable request?" An equally interesting question is "Is this an UNreasonable request?" Additionally, is it worth contention with co-authors and a stalled paper?

If 1/1000 star systems were inhabited, and you could destroy all the defenses of (assuming this counts as conquering) one system and travel to the next all in one second, it would take about 19 years to do it in our galaxy of 600,000,000,000 stars. Depending on your universe, the logistics are screaming against this being practical, let alone the politics of the situation.

Does the effect apply with other forms of communication, especially writing? Does it apply when filtered through a voice modulator? Is it specific to the person or to the person's communications?
