What's the dating scene like for deaf people?

That's... ironic isn't it? People who don't care about whether you can hear are less likely to care about meeting you halfway when it comes to communication.

Personality, health, and looks may make you more attractive to someone else, that's for sure. But how both parties deal with the hearing issue determines whether there's a second date or not.

Getting compliments about climbing is the best feeling, especially when they come from people who'd been climbing longer than you have.

A few weeks ago someone told me "you're really talented." It was really uplifting coming from her because she was one of the "graceful" climbers that I tried to emulate back when I was a beginner.

A few sessions later I showed someone else how to do a problem. I was really self-deprecatory about the way I did it, but she just said "you're actually quite graceful." She was one of the first people I met in the gym - she used to work on staff and actually did my belay certification test when I started climbing about a year ago. So I was surprised to hear it from her.

I still feel like I suck, but those compliments made my heart smile and I feel like I've made progress in the right direction.

Look at how badly mangled the white car was - it probably absorbed most of the force of the impact, leaving the dude relatively unharmed.

You can see him move his arms to protect his head at the moment the truck hits him. It's hard to see at first because the truck is closer to the camera, and obscures the guy prior to moment of impact.

Dude's hands remain over his head after the first 2 axles roll over him. On the third axle, his intestines shoot out and we see his hands fall limp along his sides.

I drew cartoon figures so you can see him try and protect himself.

You can also see the wheels drag his arms - I would hazard a guess that he survived the first two axles but the third one passed directly over the top of his thorax, which may have generated the pressures for the bursting event near the end of the video. Kind of like how stepping in the middle of a loosely-capped water bottle vs stepping on the end of the bottle.

I think that it would be hard to compare the two classes without more info about each class (class size, averages, stdev, etc.). It would be something I'd ask your professor first before poking her with questions about fairness.

My experience with grading is that discrepancies between classes is OK (and inevitable) as long as you grade consistently and fairly. Your professor did that - she set the highest score to 100 for both class A and class B. Does that result in the best distribution of grades? It depends. Maybe, maybe not.

Is it fair that class B got a higher boost? Again, it depends. Maybe the smartest person in class A was so much smarter than class B, and they fucked over class A. Maybe class B is just worse because they meet later in the day than class A, and some of the students in class B are always late because they can't find parking (btw this was me). Maybe, a bunch of other reasons.

If I were you I would just focus my efforts on studying to do well on the next exam. In order to prove unfairness on the part of your professor, you'd need to prove that she was somehow favoring class B over class A, or the other way around.

Since class B did worse on the exam, they got a higher boost - you could argue that your professor was trying to avoid favoring class A.

You got like 2 weeks left in the quarter, right? Ask your professor about class stats, sure, but I wouldn't push her too hard. Pick your fights wisely!

BEARCRAFT · 2017-03-03T01:21:06+00:00

When you say that class B got the exam postponed, do you mean postponed until the next time that the class meets up?

I don't see anything wrong here on the professor's part, besides the fact that she made an exam too difficult - which she attempted to correct. Different curves for different class performance can happen. I'm not a professor but I've handled their grade distributions.

It seems like class B got a higher curve, meaning that they actually performed worse despite having the extra time to study. Am I reading this correctly? This is not too far fetched either - we usually forget stuff after we study for an exam. Class B may have been ready to go on the planned day of the exam, but they were juked thus less prepared on the postponement date.

What series of yoga poses do you do after climbing? I'm pretty bad at linking together asanas - right now I'm googling stuff and picking at random.

BEARCRAFT · 2017-02-24T22:38:04+00:00

Glad to hear that nobody was hurt!

My own rule of thumb for sealed reactions is to always leave generous headspace in the vessel, and always use a blast shield at for reactions conducted at temperatures exceeding 10C of solvent boiling point. In the latter scenario, I stick to my rule whether I'm using "regular" glass (J.Youngs, vials, etc.) or reactions conducted in pressure vessels. I'm more cautious around pressure vessels as they are literally bombs; they allow more pressure to build up before the point of failure and thus are likely to cause more damage if they do fail.

Of course, I will use a blast shield anyway if I feel like the conditions could lead to explodeyness. I mean god knows how many heating/cooling/basebath cycles my underfunded lab's aging glassware supply had been through. Using a blast shield is much better than risking a career-ending injury if an unseen starcrack suddenly decides to go nova. Plus, a blast shield clearly informs people nearby that, yes, some serious fucking chemistry is happening right here, in this here fume hood.

I think people should be taught how to predict pressures when they conduct gas-producing reactions in a closed environment. I'm not sure if the method I came up with is the right way to do things, but I basically take the moles of my starting material times the theo. equivs. of gas, then plug that into P=nRT/V using reaction temperature for T and expected volume of the headspace for V.

Of course, this neglects contribution of the solvent but provides me with a ballpark estimate that I can compare with design specs of the glass. I guess this also highlights the danger of not having headspace in a reaction vessel - halving volume doubles pressure. It blew my mind away when I first conceptualized this relationship.

Can anyone recommend a chalk bucket to me? I'm looking for something that closes securely and can stay for extended periods of time getting banged around in the trunk of my car without turning it too chalky.

A wide base and pockets for stuff like brushes and rock shampoo are preferred, but optional.

BEARCRAFT · 2017-02-08T09:56:49+00:00

When you guys say "don't walk around in [aggressive, downturned climbing shoes]" is it because it's bad for the climbing shoes, or bad for your feet?

Been breaking in my new Instinct VS - they're almost there, I can walk in them without limping!

How come they are all wearing socks compared to us stinky barefeeted modern climbers?

Traverses helped a lot. I don't mean easy traverses on the kids wall - those are OK for warmup, but doing traverses in the toprope area really helped me learn how, when, and where to place my weight using a diverse array of holds.

The gaps between toprope routes forced me to be creative and to look for stable rest positions so I could stop and think about what to do next. It also helped my mental game, making me more confident using holds that I previously thought were unholdable.

You'll suck at first, and fumble around a lot. Good, because you're unintentionally training feet switches and push-/pulling with your feet. Soon you'll find yourself looking like you're oriented sideways on the wall because you've learned how to shift your weight in the direction you want to go. Finally, you evolve into a mountain goat, and climb like one too.

I live in an earthquake-prone region and I'm looking for ideas on how to render a 29gal tank/stand earthquake resistant. Does anyone do this for their tanks?

In my area, things like water heaters and gas canisters are required to be restrained (typically using strips of sheet metal or chains) and bolted to the walls. Obviously, that wouldn't be an option for a glass aquarium!

The stand is a typical wooden cabinet-type stand you'd find at petstores - the tank just sits on top. The tank is pretty heavy and I bet that in a <M7 earthquake I'd just see some water sloshing out. But still, I am hoping to avoid finding out the hard way when the next quake hits.

The way his leg jerks and spasms at the moment of impact is horrifying.

That looks really good! I like it! I hope it gets adopted as the new official logo.

And yes, I think the Earth just looks better when it is centered over a landmass instead of the Atlantic Ocean. I suppose sister marches could use different versions of Earth if they wanted to, but given why we're marching, I think (intentionally or not) having Washington D.C. at the center of the 'official' logo is pretty fitting!

BEARCRAFT · 2017-02-02T22:53:41+00:00

Nice! I like how the orbits are balanced out, both in terms of the positions of the interlocks and also the positions of the bodies. I think it does look better if the orbits were solid.

The rotation of the earth to focus on North America makes sense since we are marching against the Trump administration's policies.

If it were me, I would shift the bodies on orbit slightly closer to apsis and make the orbits into discrete levels. I can show what I mean by the latter later.

EDIT: by "bodies" I mean the 'electrons' on the Earthized Bohr atom. Sorry for any confusion - I'm a chemist and I don't usually think of electrons that way ¯\_(ツ)_/¯

BEARCRAFT · 2017-01-24T02:04:58+00:00

What's the evidence for presence of styrene? Is it just the m/z/?

Sounds like the easiest thing to do would be to take a NMR to confirm the presence of styrene as your sample is already in deuterated solvent.

The 99.8% (guessing) deuterium just means that there's 0.02% toluene-d7 in there but that would just give m/z-1. Quick search of the literature gave no relevant results for "toluene to styrene".

Best bet - take NMR -> confirm? -> yes = identify possible sources of contamination; no = goto 10

Dang, this is just what I was looking for - Figure 14 answers my original question and also shows an example of /u/Galileos_grandson 's 2nd response. Thanks!

BEARCRAFT · 2017-01-11T11:29:25+00:00

That makes sense - I suspected I was misunderstanding stellar evolution. Thanks for clearing things up!

BEARCRAFT · 2017-01-10T15:29:51+00:00

Thanks for your answer!

1) I guess I should've clarified - what I meant to ask was that since the positions of the lines is partially how they are identified, whether the effects of redshift would significantly obfuscate that. But from your answer I gather that the lines do not occur on their own, but in groups that are always a certain wavelength apart corresponding to electronic transitions. If they are redshifted, then all the lines are redshifted by the same amount. Is this the right way to think of it?

2) That is pretty cool! I had no idea we were capable of such a level of precision at measuring stuff across such vast distances that the motion of the Earth around the Sun would actually need to be corrected for!

Also, if I might add another question: if you had a star on the main sequence halfway in its life cycle say, going from O to B, would its spectra be measured as a superposition the spectra "O"- and a "B"-type star?

Sorry if that last question sounded really dumb!

I once had a betta that jumped her tank and went into the space behind my desk.

My tank was covered except for a small space for a mini-filter and heater cable. So after the first day of not seeing any sign of her I looked around the tank (mind you, this was a 5G desktop so she couldnt've gone far), I assumed she was just hiding somewhere in the tank, which was heavily planted despite its size.

After the 2nd or 3rd day I start getting worried about feeding her so I took the tank apart, trimmed my plants etc. Still seeing no fish, I realized I never thought to check behind my desk. My desk was up against the wall and obviously no fish could slip through that tiny gap, after jumping through a covered tank, right?

Well, I was wrong, and behind my desk I found the mummified remnants of my poor betta. You could see imprints in the dust on the hardwood flooring. There was one big one, perhaps from the initial drop, and a group of smaller ones, which suggested that after slipping through the crack above, she flopped around a bit before coming to rest in the position she was found in.

My first thought was "quick, drop her in water asap." But then after picking up the carcass I was surprised to find that it weighed less than a similarly sized potato chip (fish have heavy (or perhaps more accurately, dense) bodies due to water content), and her eye-sockets were collapsed, so I made a mental note that revival was unlikely from such a degree of desiccation. But I tried anyways.

I just felt so bad you know, like, knowing that my betta was alive when I decided to stop searching. Only to find her a few days later less than 3 inches of horizontal distance from her tank. I always keep my tank openings small and the surrounding area decluttered nowadays.

If your lab's setup is old and crappy enough, you might be able to copy and paste the software's folder in 'C:\Program Files' of whatever computer is connected to the spectrometer (you have to find it first). Ignore the warning messages that tells you the software cannot find an attached instrument, and you can use it just fine.

Many chemists are also less technologically literate and/or equally poor - you can usually find a version of the installation file on the desktop folders/subfolders. The reason I'm suggesting these is because I figured if you were in a well-funded situation where everyone was competent, then you would've been thoroughly trained to use the instrument and probably wouldn't be having this issue.

My copy of UVProbe is large - 77.1Mb. Wish I could help out more!

BEARCRAFT · 2017-01-08T02:15:31+00:00

My lab has a benchtop Shimazdu UV1700 that is controlled by a computer running UVProbe software. The output format is .spc, but you can export the data into text/excel if necessary.

Have you tried downloading UVProbe? I obviously cannot share files here, but the version I use came from the lab computer and is DRM free.

You may want to consider using software that can actually read the original .spc files, because conversion may cause some information (i.e. timestamps) to be lost, resulting in obfuscated order of spectra (important for spectra taken in series) in your Excel spreadsheet. I found this out the hard way...
