Many years ago I knew a woman that answered with (laughing)
"Speak, Baby... It's Your Dime."

Reminds me of that girl who had "Just the two of us" on her answering machine ... until her gynecologist tried to reach her ...

GaH!
I lost track of a query that maps together logins users and roles. When I move a database around, data moves, but not so with security. And I lost track of the system views I used for the tables.

I was watching a PBS television program about glass blowing and it reminded me of the glass blower at my university's chemistry department back in the 1960's and 1970's. Amazing work.

In June, my wife and I were in Norfolk, VA and visited the Chrysler Museum and their Glass Studio across the street. We just happened to be there at the right time to see a one hour demonstration. It was pretty interesting.

Have you ever actually tried it? The force required from one's breath is surprisingly high. I could barely inflate the glass bulb at all.

In Sydney, there's a tourist trappy area called "The Rocks" with a fascinating store called Argyle Glass. I remember watching their master glassworkers creating intricate ornaments, such as dragons, unicorns, cute pussycats, kangaroos, koalas, a harley motorbike, and many other things. They made it all look so easy.

Iirc, the answer is blowing in the wind. Not sure why its there.

No, but I could tell from my university's glass blower, it wasn't easy.

There are different glasses for different applications; some are more viscous than others, some get "tired" or get "the goody" cooked out of them. https://en.wikipedia.org/wiki/Glassblowing

 

[Bystander]

Got almost as far as ring seals, http://www.ilpi.com/glassblowing/tutorial_ringseal.html , never successful with them. There's a lot more to the viscosity and bubble blowing...how does the wall thickness NOT get into a "runaway" failure mode? It can't be just the cooling of the thinner wall... Took the glassblowing for fun in grad school and am just now thinking about the physical chemistry involved.

Here, the head of meteorology services just got fired. They predicted high (70-80%) chance for storms/rains for the time of some state event (fireworks and stuff), which then so got cancelled.
Unfortunately (?) at that place, at that time there was no storm.

Do Not Ask.

Kind of annoying how some of these sites overdo the whole big-picture approach. Don't get me wrong, I'm a big-picture guy. But sometimes I just need a definition, ad when I do a search, I have to go through sites that first put you through a overview, the provide motivation. WITHOUT/BEFORE giving the actual definition. Just happened recently with "Explained/Unexplained variation.

Brits think yanks have too many guns, generally. However..this is one of the best movie scenes ever.

I liked its German title: In the land of the rocket worms!

The cast was also outstanding.

Well, I prefer the second part
I could never decide about the the first part that was it intentionally a parody or they took it seriously

Makes me wonder if I should request to see all future dates without makeup first?

I think (hope) it's rather a transition (from a makeup to a different makeup) than just one makeup

She is squeezing her chin down a little accentuate it in the first part. Guys do not have any tricks unfortunately, the only thing we can do is shave really.
If I turn up to a date looking tired, rough or old that is just tough!

According to a study in Evolution and Human Behavior (see YouTube above), men can rise in the physical attractiveness scale by 2 points if their salary was higher by a factor of 10.

Funnily, the same study found that for women to appear more attractive to men (also by 2 points), their salaries would have to increase by a factor of 1,000.

Moral of the Story: Men care about looks a lot (and very little about how much money a woman earns), while women care about money somewhat in terms of how attractive they see you as?

 

[Mayhem]

Most likely doing a degree in electronics engineering after I finish my undergraduate degree in chemistry. Tuition is free here, so that's not a problem. I don't know, just feels like the questions I had when going into chemistry have mostly been answered. Either way, I have the tools to find answers to them myself.

Also I don't want to be a desk chemist which is what 95% of chemists end up doing lol.

I could do a whole thread on this seriously. What women want? Just the right amount of sensitivity, pet a dog and get gooey near kids. Go to the gym and get that athletic look but not much bulk, that's off putting. Earn a lot, if you are not that attractive just earn more. Dress well and if you work your ass off as a baker? In sweat heat and flour every day? Tough, she wants to see a bankers garb not a baker.
Look after yourself but don't be vain, smile but really MEAN it.
You have to smile right...I mean REALLY!?

The scariest thing about all this is that these are based on studies not anecdotes.
Therefore some validity and it certainly matches up with a few life experiences.

Something went wrong somewhere, something in our Evolutionary past that is at odds with our recent social Evolution?

Where you based? Fees over 9k per year in UK.
Drug stores/Chemists/Pharmacists usually have a qualified Pharmacist who can give a quick consultation if you ask. If they are not sure they refer you back to your GP but normally they give good advice.
Also they are more connected directly with the drugs, that is their job.
They can also recommend unbranded stuff so a straight Chemist will not necessarily know any of that.
I came back from China convinced I had malaria as I got badly bitten by mosquitoes in a hotel lounge and I had huge bruises on my arms, I looked like a IV drug user.
Went to chemist, looked at the bruises, asked for the region I was in and concluded it was highly unlikely I was infected but to visit GP if I developed xyz symptoms.
This practice saves the NHS money taking up the Drs time.

So? No industrial Chemistry where you are? R&D?

This is a confusing post, but to answer: Denmark, free tuition for all education except commercial pilot + some others I imagine. Industrial chemistry is a thing, but still the majority of positions are in analytical chemistry and I don't want to do that.

I was just addressing your points.

1. You are in a decent position if you do not have University fees where you are.
2. Pharmacies have specialised individuals that provide a service that a straight Chemist would not be able to do. Processing a prescription is below what a graduate Chemist is capable of.
3. That was just an open question, you are a graduate Chemist,you must have liked and been enthused by the subject? I was just interested as EE seems like a jump.
Edit. Not a criticism, if I could have afforded to do another degree in Chemistry after my UG I probably would have done it.

It's a put off for women though be warned, they do not like serial students

Seems someone has come up with some new glasses that can be adjusted on the spot by the wearer, providing 20/20 vision. Though haven't verified it.

I like chemistry, but EE is also interesting and in the future it would be cool to work with the development of chemical analysis apparatuses.

Someone in a Math video in YT makes free use of derivatives, using df/dx=dy/dx and dx/df =dx/dy , not addressing that in some cases, y may not be well-defined if y is not globally invertible. But they made a whole host of videos for free, so I feel guilty about possibly raining on their parade.

Cool method for general parametrization of n-sphere in $\mathbb R^{n+1}$:

Start with
$Sin^2u +Cos^2u =1$

Multiply through by $Sin^2 v$:

$Sin^2 v Sin^2u + Sin^2vCos^2u=Sin^2v$ ; use $Sin^2v=1-Cos^2v$ , to get:

$(SinvSinu)^2 +(SinvCosu)^2 +Cos^2 =1$

And iterate for higher dimensions, multipliyng through by $Sin^2w$* and using/subbing $Sin^2 =1-Cos^2$.

*This must be a letter heretofore unused.

That's a good "list" of totally non-politically correct assumptions/stereotypes.

Sounds about right (on average) . . .

The dog/pet bit is very true. . .it's frequently listed as something that makes women more comfortable with you. ...

re: dressing well. . .This is anecdotal, but I usually hear complaints that guys still dress like they're in college even in their late-20's to 30's...hell, possibly even in their 40's...They wear shorts and t-shorts...or jeans and t-shirts...sweat pants and t-shirts, etc. The complain is that they don't have adult clothes.

Maybe women are naturally better dressers?

 

[BillTre]

There are a lot of asymmetries between the sexes general from a biological point of view. This includes differences in the amounts of resources invested and limitations on numbers of offspring in reproduction. To an extent, sexually different behaviors, ingrained by selection, will reflect these differences.

Making sperm vs. making eggs is a good example:
The production of an egg takes a lot more resources than an individual sperm. Post fertilization care (carrying a developing fetus if you are a mammal) is another burden on the female.
Sperm are relatively cheap to make on a sperm-by-sperm basis and they can be made in the billions.
Eggs (in mammals) are also made in limited numbers, which is a hard limited on the number of offspring. Numbers of offspring is a prime indicator of evolutionary success.

Parental care is another:
When sexually disproportionate parental care can exist 9generally, more on the females), there are good adaptive reasons for particular choices of mates by females.
For example: females would tend to choose mates with traits that indicate they would be productive (indications of wealth), feel responsible toward offspring and mate (treat dogs well?), and healthy (indicative of good genetics and long term productivity).
The Dr. Suess book Horton hatches the egg provides an alternative view of the investment of parental care, kind of like a cowbird.

There is a huge literature on mate choice and sexual differences.
There is also a lot of variation between different species.
