I teach labs for three different sciences and have acquired cautionary tales for all of them. For some reason, college students think that reading the lab manual is optional... There was a girl in my advanced animal phys lab who hated wearing protective gear (lab coats are required, face shields, haircovers and gloves are highly recommended). I kicked her out of lab twice for not wearing a lab coat. During one of our rat surgeries to test the effects of antihistamine on production of stomach acid, the process involves decanulating the stomach by inserting a lipped tube from the intestines to the sphincter of the stomach and then tying it off to collect the stomach contents. The rats were supposed to have been fasted, but the tech forgot, so the stomachs were full. Ignoring not only the order of ops for the surgery, but also my warning to cut gently, she tied tight ligatures at both ends of the stomach and set at the stomach proper with a scalpel. She leaned in close, only a few inches from where she was cutting, and dug in. The ligatures were too tight. The chunky, pink-brown stomach contents exploded all over her face. Of course she started screaming bloody murder and crying. I, professional that I am, managed to run out into the hall before I cracked up.
The French tip about ten percent for cabs. Dogs, however, do not tip and will get hair all over your back seat. I hate getting in a cab after a dog's been in it and ending up looking like a crazy cat lady who lives with her mother.
My parents never would have been okay with that when I was a teenager. Even now they'd be telling me not to do it, that it would come back to bite me someday... The fact is, we live in a relatively puritanical society. Even if you have an open mind and think of it as artistic, our media won't portray it that way. Kids today are listening to the media, not paying attention to the art. It's not consciously setting a bad example, but it can lend itself to that depending on how the media spins it.
This is actually a fun experiment in real life. All you need is a string (ones with small, horizontal stripes work best for visualization), a mechanical oscillator, and a signal generator
I'm torn between this being beautiful and being an eyesore. I've seen it in person, and the colored lights are very bright, very Vegas. During the day it's just fine (the building is white and the colored lights appear pastel when they're not on), but at night it's a little much.
@the robot child: Yes, but not necessarily because of the most obvious seeming answer. While cold water has a higher dissolved oxygen content than warm water, both are still markedly lower than the oxygen content of air. Obviously, the frog has found ways to increase his rate of oxygen uptake (increased surface-to-volume ratio, thinner diffusion barrier, decreased blood flow rate, more capillaries, etc). If you've ever pithed a frog, you know that they live for hours in dry environments, even after their lungs have been disabled. The problem with removing the frog from the damp environment is that the skin is not exclusively a respiration organ. In frogs, water contact is used to maintain ionic concentrations and the resulting gradients, remove metabolic waste products from the body, and perform a variety of other functions. Not that anybody here really cares that much about cutaneous respiration...
@ the robot child: I wouldn't necessarily say that they are "less" evolved. Their evolution shows unique physiological adaptations to their very specific environment. People generally think of pool ventilation, lung breathing, as being a marker of higher evolution, but it's not actually the most efficient method of respiration.
The lab stole my real life...
