OPEN THREAD 20200312

Basically, all legal free speech is allowed. We will assist the authorities in dealing with illegal speech. You are each other’s moderators. Have fun. And don’t forget to MAGA at nuclear levels.

After going through the elements, we now enjoy a sequence of RANDOM somewhat pseudo-random topics that will be thrown out for investigation and commentary on each open thread. At some point, in a way something like composite numbers, I will accidentally hit a second occurrence of one of them – that’s just normal.

Have fun!

Day 127 – cyclopropane

10 thoughts on “OPEN THREAD 20200312

  1. OK, the actual chemical cyclopropane is a ring of three carbon atoms (instead of six) with all the extra links filled by hydrogen C3H6. This puts the ring bonds at an angle of 60 degrees rather than their preferred 109.5 which is a source of strain within the molecule.

    It found some use as a general anesthetic because it smelled somewhat sweet, like petroleum, and rapidly induced unconsciousness. It was introduced for that use in 1934 by Ralph Waters, the father of professional anesthesia, and has not been available for that use since the mid 1980s. In medical contexts, various gases have different colors for their hookups and pressure meters — cyclopropane’s color was orange. One reason for its discontinuance is that mixing oxygen and cyclopropane is potentially explosive. It should be noted that the common welding gas acetylene is H-C-(3)-C-H, a carbon-to-carbon triple bond with two hydrogens filling extra links.

  2. A cardiac anesthesiologist is flying across the country for a conference, when a flight attendant comes running down the aisle, shouting, “Is anyone on board a cardiac anesthesiologist?!?!”

    The anesthesiologist raises his hand and announces his presence, and asks what the problem is, and whether anyone is sick.

    “Oh, no, no one’s sick, but there’s a cardiac surgeon up in first class who needs his table adjusted.”

  3. [*A doctor performs surgery using local anesthesia….*]

    “Relax, Ernest, it’s just a few cuts with a scalpel. Don’t panic,” the doctor says.

    “But, doctor, my name is not Ernest.”

    “I know… just talking to myself.”

  4. An elderly man was on the operation table awaiting a very complicated life-threatening surgical procedure and he insisted that his son-in-law, a renowned surgeon, perform the operation.

    As he was about to get the anesthesia, he spoke to his son-in-law.

    “Yes, Dad, What is it?”

    “Dont be nervous, son; just do your best — and remember, if it doesn’t go well and something happens to me, your mother-in-law will come and live with you.”

    The surgery was a great success.

  5. Bonus anesthesia story (not mine, off the intertubez) —

    “I got my wisdom teeth removed at 16. I grew up in a small, remote, white Canadian town. We had to travel to a slightly larger, slightly less remote town to visit the hospital there for the procedure. The new anesthesiologist there was a very nice Chinese doctor whose family had just moved up from the city.

    Now, and this is important later, I had JUST returned from a year away — I spent a year of High School as an exchange student in Taiwan and had only gotten back a few weeks earlier.

    Procedure happens, nothing major goes wrong, and I come-to in a hospital room in a fair bit of pain but mostly fine. My dad had driven me to the hospital and came in to see me and get me up to take me home. The minute he saw me, he burst into a laughing fit and I could tell from his face that he’d been laughing about as hard as anyone could laugh.

    Once he finally found his composure, he explained to me what had happened. The anesthesiologist and a nurse came out to the waiting room after I was put under and apparently were white as ghosts. My dad asked if anything was wrong…..and eventually the anesthesiologist, still in a daze, explained to my dad that after he had administered the anesthesia (but before I was fully out of it), I began speaking to him in fluent Mandarin — and that he thought maybe he needed to call someone to ask how it’s possible that this redneck white teenager could suddently gain the ability to speak Chinese under anesthesia.

    Needless to say, my dad thought this was hilarious and explained (to the doctor’s relief) that the white kid did already know how to speak Mandarin and that he hadn’t damaged my brain somehow.”
