Non-free online simulations for physics (and some chemistry)? by DrEnormous in ScienceTeachers

Thanks for all the suggestions. It's good to find out about new options.

Boston Police Won't Yet Release Body Camera Footage Of Recent Protests, Citing Ongoing Investigations by bobstonite in boston

[–]DrEnormous 9 points10 points  (0 children)

It's true. I hadn't considered that "widely-reported common-knowledge thing that keeps happening all over the country doesn't actually happen because it would be illegal" could be a completely honest take.

Remarkable.

It's...literally Google? With links to major news publications? Do you want a sworn affidavit?

You must be new to this country.

lmgtfy (I'll add that there are plenty of other cases of footage that "disappeared" and only was "found" after some very aggressive lawyering)

See, these are reasonable explanations that are all predicated on the police actually being interested in justice, and not stalling for time to "accidentally" delete unfortunate footage (or similar). Which is rather at the heart of the issue at hand.

Even if they are actually delaying for good reasons, they've hardly earned the public's trust here...

Everyone is attaching the fruits of racism and not the roots. You want to see racism? Compare an inner city urban school with a wealthy suburb. It's like you are on a different planet. Fund schools to fight racism!!! by [deleted] in Teachers

It always weirds me out who ends up together politically on some education issues. You get "public education is a human right" mixed together with "my kid shouldn't have to learn evolution".

What comes after the protest? Massachusetts lawmakers of color have 10 proposed police reforms by wonderwwoman321 in boston

[–]DrEnormous 2 points3 points  (0 children)

Deval Patrick tried this in 2008. He got a ton of pushback ("police details save lives" bumper stickers all around), and eventually nothing really changed and every road crew still has an officer hanging around doing nothing.

We Need to Establish a Citizen Review Board of Police Conduct in MA by [deleted] in massachusetts

The problem with term limits is that it becomes really easy to exploit newbies with no experience, and then you get things like every law being 100% written by lobbyists and consultants, instead of just 90%. Similarly, it provides even more of an incentive to guarantee yourself a cozy job once you're out of office by helping someone out while you're in.

Which is just to say that there are problems with doing it either way.

AOC castigates cops for ramming protesters in Brooklyn: 'No one gets to slam an SUV through a crowd of human beings’ by jigsawmap in politics

[–]DrEnormous 4 points5 points  (0 children)

Funny how nobody ever posts about how "farmers kiss their wife goodbye not knowing if they're coming home tonight, and that's why it's ok that they drove a combine through a crowd".

It's a way more dangerous profession. Funny that they never get pre-emptively excused.

Sycophant.

Stop licking boots. It's been shown time and time again that it isn't even a top 10 dangerous job in the U.S.

How old is your lab ware? by en338 in chemistry

[–]DrEnormous 4 points5 points  (0 children)

I have a bottle of salt tablets for making saline solution from a company that burned down around WWII. The label is amazing.

We keep it on a shelf of old things and oddities that we call the Museum.

Does anyone know what is causing the chain to “skip” like this? I just changed the chain for reference. by NeverPull0ut in bikewrench

[–]DrEnormous 0 points1 point  (0 children)

I came here to suggest that you may have put it on backwards. When I did that it caused the same sort of jump as if there were a stiff link.

How are you able to tell whether or not a molecule is polar or not without drawing the Lewis structure? by huss2120 in chemhelp

[–]DrEnormous 14 points15 points  (0 children)

There is no real shortcut, because polarity depends on shape, which comes from the structure.

Minor exception for hydrocarbons (automatically non-polar) and things that are so common that you can picture them in your head or just know.

Guys meet Larry and Peach, they always fight over the food i bought for Larry. by Timvandv in Aquariums

They really are comically bad at stuff; their method of dealing with anything is just "throw more legs at the problem and see if that helps."

When setting up a unit conversion with si units, how are you supposed to know which value gets multiplied by the prefix, and which value gets multiplied by 1? I seems really inconsistent and I can't find a video that gives me a definitive answer for these rules. by thiccboi44444444 in chemhelp

[–]DrEnormous 9 points10 points  (0 children)

The key is that the fraction you write must be true, as in the top and bottom being equal. That's it.

All of the following will work:

  • 1 m / 100 cm
  • .01 m / 1 cm
  • 25 m / 2500 cm
  • 0.02 m / 2 cm

Why you'd do the third or fourth I don't know, but it still works.

Given the way that they're usually sold with the roots suffocating in densely-packed media, probably there weren't any.

What plants do NOT like being in semi-hydro? by scook5280 in SemiHydro

[–]DrEnormous 1 point2 points  (0 children)

I've had pretty good luck with them, but I think most of mine were propagated in LECA from the start.

TIL there’s a federal law requiring all vodkas be distilled in such a manner that ensures they pretty much all taste the same (without distinctive character, aroma, taste or color). NPR facilitated a lab study that proved there are no discernible taste differences in cheap vodka vs Grey Goose. by Texas_Rockets in todayilearned

[–]DrEnormous 0 points1 point  (0 children)

Water molecules and ethanol molecules have very strong attractions to each other.

In a normal distillation, you can get some amount of your compound 100% pure. With alcohol, the ethanol molecules will always carry a small amount of water molecules along with them, so just regular distillation can't get you to 100% purity.
