hannza lab glassware (33 comments)

The supervisor's right - they should return them sooner.

Honestly, nothing drove me more nuts than people being inconsiderate with communal glassware. My lab was excellently equipped, with a more than sufficient supply of glassware for the people working there - if they were kept in circulation, that is. Instead they sat in fridges, freezers, in the back of fumehoods, often unlabelled and far past the point of their contents being important or, in some cases, even known.

It's bad lab practice. Keep stocks of intermediates etc. in cleaned out reagent bottles. Keep small samples in glass vials or other "disposable" glassware. Don't store your NMR tubes or marker pens in glassware (I'm not making these examples up).

Although, thinking back on it, maybe that stuff was only really bugging me because it was the last six months of my PhD and *everything* was bugging me...

I would have been quite annoyed at that. Hell, I even get annoyed when the people near my lab bench have a bunch of glassware (UNLABELED) scattered around and encroaching on my workspace. It's not like we're heating 12M HCl every day, but even if we're using .15M KI in water, it's not that hard to label things and keep a lab space organized! of course, some of these people have to be reminded about using the right disposal container...

but then, we're not PhD students

hannza Re:Paywalls (33 comments)

As an academic, I would describe it as more like living in a nightmare.

yeah. it's hell. I think a lot of students pay more fore textbooks than they do for food. Since I'm a science major, I'm usually required to get the new editions, which are twice the cost of the previous edition. Of course, most of the information in the old edition is outdated...

I can definitely see how this could be useful, especially in research labs. but with budgets in the state they are, it'll be years before public universities will get a chance to even think about applying this technology.

National Planetary Exploration Car Wash and Bake Sale

hannza attention (103 comments)

I think it's a good idea to draw attention to the issue, but I dunno how much coverage it will get. I know the news where I live tends to focus on local politics and crime, the weather, sports, and current national stuff.

of course, they might just throw it in as a 'local event,' ignoring the fact that it's going on around the country.

The Laws of Physics Trump Traffic Laws

hannza Re:Quantum Physics trumps everything (378 comments)

"But officer, since I didn't observe the stop sign, it was both there and not there at the same time. It was there after YOU observed it, but by that time I was already gone!"

"If you knew where I was, then how do you know how fast I was going?"

Robotic Squirrels Battle It Out With Rattlesnakes

hannza Re:Is this trait unique to the Grey Squirrel? (125 comments)

Yeah, the species studied is Spermophilus beecheyi, the California Ground Squirrel.
The grey squirrels in the US are Sciurus griseus (the Western Grey squirrel), Sciurus arizonensis (Arizona grey) and Sciurus carolinensis (the Eastern Grey squirrel), and the 'red' (more brownish) squirrels in the US are Sciurus niger (the fox squirrel, pretty much all over North America) and Tamiasciurus hudsonicus (red squirrel). The red squirrels in the UK are most likely Sciurus vulgaris (the Eurasian red squirrel) and the grey ones are likely Sciurus carolinensis as well, as the species was introduced to Europe.

Robotic Squirrels Battle It Out With Rattlesnakes

hannza respect the squirrels (125 comments)

(Eyes furry rodent hanging out at the bird feeder with a bit more respect.)

I honestly think that the squirrels around my house are smarter than my dogs (of course that's not saying much). And there are sooooo many crazy squirrel stories I could tell...

Suffice to say, once one of the squirrels stole my coffee, I had very little trouble with choosing my subject for an ethology project.

When it comes to 3D TV:

hannza subtlety (404 comments)

That scene (and to a further extent, that movie) have pretty much formed my opinion on 3D tech: Use it to enhance the movie without being distracting. and don't make the whole damn thing about 'omigod! it's 3d!.' When Coraline first came out, my friends and I saw it in 3D. the effects didn't jump out at you and scream 3D- they just sort of lifted everything to a different level (the one exception: the big needle in the very beginning). I've watched Coraline several other times- a couple times on my family's HD tv, and a few times on my laptop. I could tell the difference between the the 2 and 3D versions, but I think the most important thing is the fact that it doesn't matter if it's in two or three dimensions. The movie is still great. The animation is still amazing. The 3D efffects were subtle enough that they didn't affect the movie or animation, but they were vivid enough to make it worth the extra $2 to see it in 3D. Other than that, I tend to avoid 3d stuff. Even if glasses aren't needed, my vision is bad enough that my eyes start to hurt. and if glasses are needed? I have enough trouble wearing chemical safety goggles over my regular glasses- and I'm almost blind without them.

Books I bought to read, but haven't yet:

hannza I run out of books sooo quickly (298 comments)

I love to read, and I'm a really really fast reader, so whenever I go to the bookstore i get as many books as I can afford to (usually about 15 if they're paperbacks), and it takes me maybe a week to read them all if I have a lot of other stuff to do. and no, I do not have a kindle. it would be amazing for travel, reading in bed, etc, but I would spend all my money in one day on ebooks.

Are You Prepared For the Zombie Apocalypse?

hannza Re:Easy (515 comments)

where I live, the seasons are: Cold/rainy and Really hot/dry. so, zombies would rot and melt, or they would mummify and be very flammable. for the tougher zombies, I'd just use the swords I have or just use a chainsaw.

Leonardo DiCaprio To Play Alan Turing?

hannza Re:Lots of interesting angles (269 comments)

A Cryptonomicon movie would be amazing, but I don't think that it would end up being a major movie- too easy to mess up, and I can't imagine that many screenplay writers or directors could fully translate the span or depth of Cryptonomicon.
