  • Perhaps they were thinking of an American doctor.

    The bowling pins are for hitting the patient on the head because that’s the only anesthesia they can afford. The ducks are the little birdies circling the patient’s head after the anesthetic bludgeoning has been administered.

    The first gun is there because America and the second gun is so you can double-tap the patient in case you suspect they might be an immigrant.





  • No. Firstly, no means of contraception is 100% effective; stacking them further reduces the likelihood of unwanted conception. Defense in depth is your friend.

    Also, sometimes people can catch something without being aware of it. He might have an infection he’s not aware of. You might have one. The condom protects both of you. If you want to do it without, get yourselves tested.

    And all of that is under the assumption that everyone is honest and has the best of intentions, which… isn’t always the case.







  • Unless other situations where the established technology wins due to inertia, sodium ion batteries have two benefits that make them interesting regardless:

    Firstly, they are safer. A punctured sodium ion battery doesn’t catch fire, which massively simplifies safety design. That makes them very attractive for certain scenarios, especially ones where density is a secondary concern. That in turn means they get further development money instead of withering on the vine.

    Secondly, they require fewer hard-to-obtain materials, which makes them attractive from a strategic perspective. This one should be less important than the safety factor but it’s also relevant.

    I’m pretty sure we’ll actually see wet sodium cells in the wild if they are actually practical. Sodium ion tech is already being commercialized and if this brings it within the same ballpark as lithium ion then it becomes a very interesting choice for vehicles due to instant crash safety gains.



  • My high school had a few unusual traditions around graduation time.

    The first related to our director, a man who gave his 100% on official school business and then gave another 100% on all of his hobby projects around the school. It wasn’t that we had something like an apiary or a pond biotope. We had an apiary and a pond biotope and a herd of goats and a tiny vineyard (in an area mostly unsuitable for wine) and a shelter for emotionally disturbed aras. In a public school. And all that besides him being a highly respected director and teacher who epitomized the definition of “strict but fair”.

    So at some point the students started to express their gratitude by giving the school presents upon graduation, usually themed around the director. The gym sported a Jurassic Park sign, except with the name of the school and with the profile of the T-Rex replaced with that of the director. In another year someone had contacts with the roads office and got something that looked like an official city limits sign made, except that it identified the school along with “administrative region <director’s name>”. Very cool; he took that one with him when he retired.

    Another tradition is somewhat common in the region: The “chaos day”, effectively a formalized graduation prank. At my school, it worked like this: The evening before, the students were given a copy of the keys to the school and free access to the school grounds to prepare. The next day they had to prevent the teachers from entering the building; if a teacher got in, school would resume as per normal. The teachers had a fairly good track record. Many graduating classes failed to account for the fact that the teachers had bolt cutters. One time they didn’t account for an obscure window at the back of the school, which happened to be an emergency exit and had an external lock.

    My year didn’t take any chances. I come from a fairly rural area so we had farmers in class and those farmers had forklifts and hay bales. By the time school was supposed to start, all entrances to the building had solid walls of hay in front of them. We also immediately cashiered any teacher who entered the school grounds and forced them into party activities. I have fond memories of hearing my class teacher horribly butcher Oh my darling, Clementine before wandering off to listen to the school band play Hurra, hurra, die Schule brennt.
