		<description>I think its safe to say the growth of a child in microgravity would be severely impacted...

I would think it unlikely a child that matured in microgravity would ever be able to return to gravity safely. Not that this is likely to be an issue anytime soon.

		<description>I worked in a very male dominated environment and that kind of thing is (hopefully was, I chose to walk away from it some 25 years ago) common place. I didn’t find your story at all unusual or surprising.</description>

		<description>I do wonder what the effect of micro-gravity would be on pregnancy... I suspect it would not be good. 

However there is this paper: https://pubmed.ncbi.nlm.nih.gov/9502520/#:~:text=Ten%20rats%20spent%20days%20nine,growth%20and%20somatic%20motor%20development.



&lt;blockquote&gt;Sprague-Dawley rats were studied to learn whether gestation in the near-zero gravity, high radiation environment of space impacts selected mammalian postnatal events. Ten rats spent days nine to twenty of pregnancy aboard the space shuttle orbiter Atlantis (STS-66). Their movement was studied shortly after return to Earth; subsequently, several of their offspring were cross-fostered and examined through postnatal day 81 (P81) for whole body growth and somatic motor development. Values for the flight animals were compared to ground-based control groups. Relative to controls, the pregnant flight rats showed a marked paucity of locomotion during the first few hours after returning to Earth. There was greater likelihood of perinatal morbidity for the offspring of flight dams when compared to the control groups. Whole body weight of surviving offspring, averaged for each group separately, showed typical sigmoidal growth curves when plotted against postnatal age. The flight group for our study had a larger ratio of female to male pups, and that was sufficient to account for the lower average daily weight gained by the flight animals when compared to the control groups. Walking was universally achieved by P13 and preceded eye opening, which was complete in all pups by P17. Thus, both of these developmental horizons were attained on schedule in the flight as well as the control rats. Characteristic changes were observed in hind limb step length and gait width as the pups grew. These patterns occurred at the same time in each group of rats. Therefore, prenatal space flight from days nine to twenty of gestation did not interfere with the establishment of normal patterns for hind paw placement during walking. &lt;/blockquote&gt;



Only the latter half of gestation was spent in microgravity but- as &lt;a href=&quot;https://pubmed.ncbi.nlm.nih.gov/15607544/&quot; target=&quot;_blank&quot; rel=&quot;nofollow&quot;&gt;this paper&lt;/a&gt; argues- it is the latter parts of gestation that would be most vulnerable to micro-gravity effects.



&lt;blockquote&gt;Up to the 21-22nd gestation week the fetus is in conditions similar to neutral floating, while after the 26th gestation week the apparent weight of the fetus is 60-80% of the actual weight. Decreased effect of the buoyant forces that affect the fetus in human species during the last trimester has a number of implications for the colonization of the solar system. During space flight it is impossible to apply the existing countermeasures against microgravity deconditioning of the muscular and cardiovascular systems to the fetus. Absence of gravitational loading during the last trimester of gestation would cause hypotrophy of the spinal extensors and lower extremities muscles, reduction in the amount of myosin heavy chain type I in the extensor muscles of the trunk and legs, hypoplasy and osteopeny of the vertebras and lower extremities long bones, and hypotrophy of the left ventricle of the heart muscle.&lt;/blockquote&gt;

		<description>I hate this crap.

Sadly, the Geosciences have always been a boy&#039;s club.

Many years ago, I worked for a major mining company. Our work was pretty minor to their spreadsheets, a backwater, a wildcat operation they threw some money at for a tax write off.

But every year, the big wigs would come to town, or out to the field to check up on us and have a vacation and some per diem.

Our team was six people, four guys, two women.

On one of these visits, after a long day of presentations, the big wigs decided that an after-dinner trip to a strip club was in order. Our female co-workers were not invited, of course - but I was.

I told my boss that I was not interested in going to a strip club.

He told me, and I&#039;ll never forget it, that it would be good for my career with the company if I went. There was also the tone that it would be bad for my career with the company if I did not go watch women be objectified.

So...

I didn&#039;t go. 

And I did not have a career with that company.</description>

		<description>I asked him a question and his reply started with ‘I don’t know how much you know about X so I’ll keep it simple’

I had no further questions for him.</description>

		<description>Well, &#039;funny&#039; probably isn&#039;t the word I am looking for...
When I was a physics undergrad I worked part time in the lab for one of the professors- one of the post-docs in the lab was in training to be an astronaut... I can only imagine what would happen to someone voicing those sort of speculations in her presence...

In addition to everything else, she had a black belt in at least one martial arts style.</description>
