Was that a thing though (in the west) as the dowry was usually brought by the womans family? Wasn't it more like the womans family bying the son in order to have someone to support them. Trades was not really a thing for most people throughout history so the ability to toil in the fields were of paramount importance as the only way to support the family.


Women have always worked on farms.

A solo man couldn’t create a self-sustaining farm either, yet somehow they weren’t the ones being bought and sold “for their own benefit.”


When synchronizing two nodes A and B, where there is a persistent difference in the travel times A->B and B->A, how do you achieve synchronization when knowing A->B->A or B->A->B?


Delay symmetry is a critical assumption in any two-way time transfer process. White Rabbit goes to extreme lengths to maintain that property.

This includes mandating use of cables that share a single optical fiber, with specific wavelength pairs and fiber types so you can calibrate for unavoidable differences in propagation time.

More info on their wiki:

For a first approximation, you can assume A->B and B->A travel times are equal.

And because optical links are used, the asymmetry is mainly due to the wavelength difference which is known.


you can't. You can only assume that they are equal and attempt to make them as equal as possible. (the same issue arises when measuring the speed of light: it's actually not possible to distinguish if the speed of light is different in one direction to another, we only know accurately the average of each direction)


If they return to baseline in 30 minutes, was there even an increase to begin with? What is the mean lifetime of those cytotoxic cells, and would one expect such a decay in so short a time?

I understand that it is a very dynamic system but 30 minutes seems very short to me. So is the return a die-off or where do they go?


The lifespan of T cells varies from months to years (memory T cells). T cell development begins in the bone marrow and continues in the lymphatic tissue and periphery. During their lifespan, these cells circulate in the body and migrate based on chemical gradients.

What happens when you exercise? Blood pressure increases, blood vessels dilate. I honestly would not be surprised if what these authors observed was just existing T cells in capillary beds being kicked up into circulation, only to adhere and begin to intravasate a couple minutes later.


Excellent explanation, thanks.

That seems to translate well to my layman intuition. Would there actually be a health benefit with respect to cancer (or pathogenic disease) from this "T cell migration"? Is there a sense in which migration of T cells spread information to different parts of the body or is this just not how it works?


I have seen plenty of miss-use of solutions of the following though:

1. Struggle with exercise.

2. Check proposed solution.

3. Thinking that your understanding of the proposed solution constitutes an ability to solve it yourself.

This is analogous to the original problem, where you assume the ability to follow reasoning translates to being able to reproduce it.

The main use of exercises without solutions is to try and force students to go to their teachers and interact, so that someone can try to pinpoint what exactly the missunderstanding is.

This can probably be better done with assigned homework. However grading can be time consuming, so trying to filter so that only those that have problem with specific exercises come to see you is one way to try and get some time economy going.

Also yeah. This is better in course specific work sheets than in books, since books should be self contained enough to be usable without the guidence of TAs or professors.


Asking "Can you cite some legal precedence for lemon law cases?" gives an answer containing

"In California, for example, the California Supreme Court in the case of Lemon v. Kurtzman (1941) held that a vehicle which did not meet the manufacturer's express warranty was a "lemon" and the manufacturer was liable for damages."

I dont think that case exist, there is a first amendment case Lemon v. Kurtzman, 403 U.S. 602 (1971) though.

I can't find any reference to Kurtzman or 1941 in any of the references. I think the answer is that the AI generating the text, and the code supplying the references are distinct and do not interact.


Yes. But his point is that what we have been doing is more like taking on credit card debt to spend on booze than taking a bank loan to buy machinery. And assuming that being the case, your statement completely misses the mark.


Certainly people who suffer a miscarriage when trying to have children suffer deeply. It is clear then that they lost more than some human tissue.

Also if you beat a woman causing her to misscarry, then we look upon that quite a lot harsher than if no miscarriage occured.

In general we don't tend to value human life or rights when it is inconvenient to do so though.


> Also if you beat a woman causing her to miscarry

An interesting note: even in the Code of Hammurabi there's a provision for that, and that's from about 4,000 years ago.


Today I learned that there are actually six provisions in the Code of Hammurabi for that, covering different effects to the mother and (according that system) standing of the mother!

  209. If a man has struck a free woman with child, and has caused
       her to miscarry, he shall pay ten shekels for her miscarriage.
  210. If that woman die, his daughter shall be killed.
  211. If by a blow he has caused a plebian's daughter to have a
       miscarriage, he shall pay five shekels of silver.
  212. If that woman has died, he shall pay one-half mina of silver.
  213. If he struck a freeman's female slave and has caused her to
       have a miscarriage, he shall pay two shekels of silver.
  214. If that female slave has died, he shall pay one-third mina of
       silver.


This also shows how women at that time were treated as "glorified property":

> If that woman die, his daughter shall be killed.

You damaged my property — your property will be equally damaged. Justice!

Women wouldn't be treated as equal to men for another 3,500 years or so.


Also, does that mean that according to the Code of Hammurabi, a man without any daughter, can kill as many free women as he pleases without any consequence?


  283. If a man be an insufferable pedant, he shall be put to death.


Well played


I don't think too many people tried that "crazy amazing loophole that the government doesn't want you to know about but can make you rich".

Looking at the rest of the code, it seems this sort of action is doomed by the adage, "an eye for an eye" - where a blind man might lost a hand instead of an eye.


Let us apreciate that we are not bound by the Code of Hammurabi, and strengthen our resolve to not move in that direction.


No. It is a legal principle. If there is a sign stating: "Parking prohibited 03am - 07am" then that implies that parking is allowed outside that window of time.


Well, transcription is a the transference of information between mediums. Spoken to written. Spoken to recorded media. Written to other written. But strangley not written to spoken, so the analogy breaks down there.

But if you have the understanding that transcription is a copying to another media, then the jargon makes perfect sense. People used to dictate and have a secretary transcribe. But we don't do that any more. And like the sound of a typewrighter the verb "transcribe" has drifted out of common parlance and might therefor gone a bit stale as an analogy.


But non of that is _peer_ recognition. HR is not your peer, your boss is probably not your peer, your coworkers are probably your peers.

I would think that your peers are the people you socialize with. If you never had a non work-related conversation with someone, you most likely don't see them as your peer.

People pretending to be your peers, pretending to appreciate you, wont feel rewarding. But you willingly do things for the people you like and hang around with without remuneration. Is your wife, your sibliblings, or your friendly neighbour not your peers?

If you have no peers, whose recognition you appreciate, at work. Then there is something wrong with the work environment and that problem is probablh management.


Sorry, but that's a bit childish.

My co-workers are not my social group except for the time I put in at work. That's the beginning and the end of my relationship with them and it's like that for most people who have families of their own. Our relationships are as organic as they can be in a work environment, we don't bullshit each other, and while a toxic relationship with a co-worker might drive someone away, no amount of hand-holding and friendship-having is going to stop someone for leaving for a pay increase. At some point, all business relationships end and all you're left with is what you managed to earn with your time and effort.
