Chemists, lab managers, etc. in industry: which programming language, if any, do you get the most use out of in your job?

I work as a lab tech at a small company and we live and die by our IT guys when it comes to the data entry/processing part of the job. I find myself wishing I had a little BASIC knowledge so I could have at least an inkling of how our macros work (when they work). What kind of fundamental programming skills are good for someone looking at a lifetime working in labs?

All of them. Currently working on a project that uses C, C++, C#, python, perl, matlab, mathematica, and a hint of fortran. For the love of god don't do this. I want to die.

Check out python. I also highly recommend fucking around with openbabel for chemistry shit.

Isn't python the dominant language for academic and scientific stuff?

There is always C/C++ But that's mostly for libraries. They often have python bindings.

Stimming: is the repetition of physical movements, sounds, or repetitive movement of objects common in individuals with developmental disabilities, but most prevalent in people with autism spectrum disorders.

I've been trying to solve the last one all day with no success.
Please point me in the right direction. I realize the codimension is basically generalized dimension except moving sets around instead of points, thats about it. I only got 4 hours of sleep last night because I tried and failed so many times on this

if V is a finite dimensional vector space, this is easy since dim(N1) = dim(N2), so dim(N1/N) = dim(N1) - dim(N) = dim(N2) - dim(N) = dim(N2/N)

does / operate just like set difference?

for an infinite dimensional V, i don't even know where to start, and i'm curious what the answer is.
>>
>>9034196
>does / operate just like set difference?
no, because then N/N1 wouldn't have a zero vector and wouldn't be a vector space

Despite apparently not knowing what / means here that is correct if V is finite dimensional

According to special relativity, the photon doesn't experience time and space (A and B are next to each other).

Then, how come it travels and even takes a long time to reach distant destinations in the universe?

Back in the old days, we hardly knew anything.

Now we know and can control our bodies to a much wider extent (meditation, thinking capabilities, dream control) because we trained ourselves to.

There was once a guy who climbed everest in his shorts because he trained his body to lower its body temperature to survive.

My question is this: Are we capable of, in the fat future, changing the very cells within our body at will?

We have already seen evidence of this, and it is largely a subject that isn't given a lot of credit, but has a lot of potential.

We might even be able to change our eye colour in due course. We can regulate our breathing, our thoughts, etc. Basically changing our cells. Why not eyes or other cells?

>There was once a guy who climbed everest in his shorts because he trained his body to lower its body temperature to survive.
thats because its low moisture and his legs were making heat. plus he probably had a layer on his torso of sorts just to keep his sweat from freezing or wind chill from fucking him up.

i climbed a mt baker on the glacier side, it was cold as fuck but you were only wearing like a quarterzip because the amount of exertion you put in made you hot.

people have been meditating since china, dream control is just suggestion or self hypnosis whatever you want to call it


no, you will always be fat unless you somehow had an ability to make the decision to diet

>why not eyes or other cells
i cant speak for other cells because you do control them in an indirect way with stress reactions or eating, but there's no reason to think we could change the color of our eyes, that would be like changing skin pigment with your thoughts
>>
>>9033164
I could lose myself in those eyes.
I feel it coming babe.
>>
>>9033174
The use of our brains is training. From birth. The use of our lungs, eyes, muscles, breathing, trained.

We don't have full body control yet because we haven't got the knowledge of how to train it fully yet. Even drugs which are self administered change our very conscious perception.

Which means that in the future, yes, I can totally see people changing their eye colours through their own thoughts.

The UK has a system similar to the US, except I believe 90% of the universities are state universities. In terms of prestige and competition is works just like in the US.

For the rest of Europe you have two situations.

You have countries with entrance examinations and a few prestigious universities, mostly just because they enrol the top ..% of the country. France is one example.

And you have countries where it's easier to get into university. In these countries there isn't really all that much difference in prestige, especially at undergrad level. Prestige is gained solely because of continued excellence in research. The Netherlands, Germany, all of the Nordics are like this.

For 3rd world countries it's always the same recipe. Few state universities. Very hard to get in. Very prestigious. Some private universities. You pay to get in. Considered a joke.

Spic here

A few years ago you would be right, but now every retard can enter UNAM. It's still prestigious though.

>>9033121
Belgium here. We use the ECTS (European Credit Transfer and Accumulation System)

College is 3 years. Then you get what we call a "professional bachelor"

University is split into 2 parts.
-academic bachelor part (3 years)
-master degree part (2 years)

Though it's possible to quit and get a job after getting your academic bachelor, the system is set up in a way that most people continue and get their masters degree that directly follows their bachelor.
People who were never interested in getting a masters in the first place go for a professional bachelor in college.
There are some exceptions of course. But this holds true for most tracks.

Generally there are no entry requirement other than a highschool diploma. Except for med fags who have to take an entrance exam. Engineers also have one but only in Wallonia.

Nobody cares about things like GPA or prestige.

there are lot of different ways to behold this game. i like to think of it as a rainbow of failed ideas. some of these terrible ideas collapsed on themselves and disappeared. some of these terrible ideas interacted with each other in any number of different ways. and some of these terrible ideas swallowed other, less terrible ideas whole.
we don't have the details of how, exactly, all of this came to be. there are some things we know, and there are a lot of very safe guesses and projections.
one thing we do know is that this was once an nfl game between the denver broncos and pittsburgh steelers. it almost certainly started in the 21st century, probably the 2080s or 2090s. over the next 15,000 years, the two-team system faded away. outside teams, people, and interests began to interfere in the game, eventually claiming territory.
the game is divided into 58 territories. the broncos and steelers each still have their own territory.
Territory 1 is claimed by the Broncos, who have refused to participate in any of this evolution. their territory remains completely unaltered. the hash marks are freshly painted, and the players still show up every Sunday in helmets and pads. they insist, without any success, that the game return to how it used to be. a wall stands between their territory and their others, though no one remembers for sure who built it.
the Steelers exist, but barely. their territory, which once covered half the field, is now reduced to a single, tiny corner. they would've disappeared from the field entirely were it not for the Broncos, who leveraged whatever political power they had to ensure their opponent was still in the game. there's one Steelers player who still comes back every 500 years or so. they call him the Last Steeler. he just kinda drags a stool out there and sits there for an afternoon and then leaves.
