Oh, I stand corrected: Indoor plumbing will only take 347,000 years.

by omar_a1 7y ago
30 years is an underestimate. Homo sapiens have been around 350,000 years. We've only had indoor plumbing for the last 200 or so. It took 349,800 years for us to install a toilet. Constructing a pyramid took 346,000 years. Granted, the

Don't forget the ridiculous propaganda being pushed by the fossil fuel industry, if the slew of climate denialist rebuttals to your comment are any indication...

Do file for Unemployment Insurance. It might not apply to your role or circumstances, but it's worth exploring if you don't have savings. (NB: Some employers reject legitimate unemployment claims as a matter of course. It often ma

I fail to see how quickly shutting the hood in cases of catastrophic failure address my concerns. When you're dealing with pressure differentials and compressed gasses, explosions and implosions are a very real risk, and shutting the f

Only if we ignore that HF is volatile, meaning that you're dealing with much more (not dissociated) HF evolving from your reagents. Even with a fume hood, you've got much more HF in your face versus a 5% concentration. Calcium glu

As in, a highly pressurized gas canister? In a container that is presumably 100% impervious to HF corrosion, yet somehow also made out of a material that can withstand those pressures? How is that safer than neutral-pressure, aqueous HF? I&

I think you're not paranoid enough about HF. It doesn't wash off, and is small enough to pass through skin to form insoluble mineral precipitate with calcium in bone and blood, which can result in amputations from dead tissue. It&

Start with an entry-level job in an MCB lab (standard bench work: pipetting, plating, PCR/PAGE, wet chemistry, etc.), and build upon that experience to get opportunities to do more sophisticated techniques, eventually leading to geneti

Yes, but did they understand that the change occurring was a physical one, rather than a chemical one? As opposed to cooking other forms of food and beverage save for ice, which would fall under chemical reactions rather than phase transiti

My money's on No, because of a slightly related psychological concept: conservation . Conservation is the cognitive understanding of whether or not the amount of a given (inert) solid or liquid will change despite its presentation. Fo

To be fair, this is also done in every other STEM field, and CS is no exception. We could all learn a lot more from each other if everything wasn't a contest all the time.

I've seen so much bad math and misunderstood statistics hard coded into widely-implemented software that that's not ideal either. Ultimately, you need a team with a combination of strengths if your product requires multidisciplina

Genetics and evolutionary ecology falls into the category of "layers of abstraction." Mechanisms for up and down-regulation, self-catalysis, epigenetic. You're convoluting the simplicity of each step of an experiment with the

I'd say there's no subtitute for hands on experience. In the same way people on here recommend writing your own project to learn a language over simply reading about it, actually doing lab work gives you an understanding that no b

I was coming into this thread to recommend looking for entry level part time mcb/bio lab work precisely because of point #1. It's a wax on, wax off thing. The repetition gives you a chance to reflect on the rationale for your tech

Solvation is part of it (particularly for soaps and mineral spirits), but the main factors are oxidation and, as you stated, acid/pH. Oxidation removes organic stains (e.g. foods, mold-stains) and, depending on the strength, disinfects

I've had this happen too. Also, lots of vagueness about what the technical interview entails, whether in terms of tech stack, format (Q&A? Coding exercises? Discussion-based?), or domain of questions (Pure algorithms? Specific appl

I'm in the same boat. I know I would do the job well, but I'm not a good test-taker. And even when I manage to perform really well on the tech screen, I still get rejected. Stay strong, OP.

Would have flagged, but didn't realize it was possible (not at the karma threshold). Will keep in mind for future reference.

No dear, you're just trying to legitimize the 'White Genocide, protect our pure race' Nazi rhetoric by playing the victim. (Nice co-opting of the word "gaslighting" by the way. Very convincing!) Calling out your bul

Yes, why won't anyone think about the plight of the White Supremacist anymore. Just awful. What fucking year is this again?

This is assuming we act before any of the global homeostasis mechanisms break due to the CO2 levels (jet stream, thermohaline cycle, methane clatharates, etc. etc.), in which case it'll take far more money (and research).

We can fund the God damn research, for one. Of course, for that we'd need a functional government.

"what is already well known and understood via Chemistry, and sure some of that is inherently just fronting quantum mechanics behind the scenes." This is actually my main point. I'm not intending to reduce or dismiss (bio)che

Maybe I'm just using a less narrow definition of quantum mechanics? I'm not referring to the specific quantum phenomena referenced in the article, but to quantum mechanics in general. In other words, since these redox steps are ha

I was also confused about the assertion that biologists dismissed quantum mechanic's affects on biological systems. Biochemists have known about this phenomenon for decades , including photosynthesis.

I've been unemployed for four months now. And, ironically, have been overworked preparing for the slew of technical interviews I've had these past two weeks (four just this week). If you had asked me this question a few weeks ago,
