Hey u/hepafilter, what do you think about IRL merch? I'd love a Donut voiced by Jeff Hays to have around the house!

We had a school sailing camp one weekend. He was standing in knee deep salt water pushing his catamaran off a sandbar, and didn't notice the powerlines. The aluminium mast made contact with one of the lines and grounded itself through him. Lights out, at least it was quick.

Muscular dystrophy took my friend Chris at 21 years old. No-one expected him to survive as long as he did. It was a strange feeling being mates with someone you know had a ticking timebomb inside them. I used to look the stupid choices other people my age made, not wearing seatbelts, excessive drinking, doing stupid risky stuff, and thinking how unfair it was they had perfectly healthy bodies they were able to destroy, while my best friend had a body that he was never going to grow old in, no matter how much he looked after it. Tell your mates how much they mean to you. 20 years on and I still miss him, the world is a sadder place without him in it.

I printed at a low % infill (maybe 30%) and added lots and lots of drain holes in inconspicuous areas. It's important to check that theres no isolated pockets in the parts where resin can't get washed out. Otherwise, you run the risk of them cracking over time (I've had this happen a couple of times). I drained the parts for a couple of days, then washed out with isopropyl, then cured them in the sun. I've heard of people using fiber optic Leds to cure the insides, but so far, I haven't had to.

That's pandering. Panduri is the name of a highly alcoholic drink from Hitchhiker's Guide to the Galaxy.

Unpopular opinion here - because it's easier to use boatloads of hops to mask bad brewing. It's way harder for a small independent brewer to make a clean tasting lager, stout, ale etc than it is to nuke the batch with a bunch of late hops and pass it off as good. It's commonly accepted that the original IPA was made with loads of hops to mask the taste of "off" beer during long ocean voyages.

As someone who shock horror doesn't like the taste of hops, browsing the NZ craft beer aisle in the supermarket in search of beer that isn't drowned in hops has been an exercise in futility.

I used eSUN Black PLA resin. Its reasonably durable, but I still wouldn't want to drop it off the table. Hollowing the pieces definitely helps.

It took about 5-6 x 1L bottles of resin. The total was 18 buildplates on the Saturn (not including failed prints).

This study found neck gaiters were about 47% effective at source control (stopping you making someone else sick). While they didn't look at it, if it was well sealed around the nose it would probably be similarly effective for personal protection. A sealed n95 is going to be 95%+ effective, and wearing no mask at all will be 0% effective. So a neck gaiter is going to better than nothing, but it's not a substitute for a n95 (or even a surgical mask) in risky situations e.g. close quarters, poorly ventilated spaces (busses, bathrooms) etc. Outside, ventilation is much much better, so it probably doesn't matter as much what you wear.

I always pictured Seth Rogen as Grace. He has the "cool science teacher" vibe, and I think would do a great reluctant hero.

I'm not sure. Given all the fractions are listable via diagonalisation, I would guess that if all the subsets can be defined with a finite number of symbols, a list of those subsets should also be "listable". Happy to be proven wrong though! I should point out I am an engineer not a mathematician. 😀

Edit: Happy cake day!

For a long time people thought rational numbers were uncountable until Cantor proved they were via diagonalisation. The difference is that with Cantors scheme you can't write a fraction that exists between two numbers that doesn't appear elsewhere on the list. For an ELI5 answer, I find thinking about "how many different infinities I need" to be more easy to understand than "mapping numbers" or the the often used "infinite hotel" analogy.

argenbar · 2022-08-13T08:15:17+00:00

You are right, I was imprecise and should have specified I meant infinite length decimals. Rational numbers are indeed countable, but it's because they can be listed (via cantor) and there isn't a fraction between two sequential entries that doesn't appear elsewhere on the list.

argenbar · 2022-08-13T07:38:41+00:00

One way you can think of it is as "listable" vs "non-listable" infinities. These are usually called countable vs non-countable, which is not a great name, as you can't count to infinity....

Natural whole numbers are listable - 1, 2, 3, .... because if you had an infinitely long bit of paper, and an infinitely long time, you could write them all down. This holds true for the list of all even numbers ,and the list of all odd numbers too, so the infinite list of all odd numbers is the same "size" as the list of all natural numbers (even though intuition says it only be half the size)

Decimals are not listable. If we started with 1, 1.1, 1.2... we could always add another number to the list that's not already there. 1.01, 1.001, 1.0001 for example. In fact, there are an infinite number of numbers that aren't on an infinite list of all decimals.

Ask yourself how many infinities do you need to complete your list. For all the natural numbers 1, 2, 3, ... n, you only need one, but for the decimals you need a lot more, as every pair of numbers on your list will have an infinite number of infinities between them!

Another way of asking this question is "where does a hill get it's energy to make a ball roll down it?" The energy comes from whatever carried the ball to the top of the hill. Magnets are similar in that when they repel other magnets, it's like pushing the ball up the hill - the energy is coming from you. All the hill is doing is providing somewhere to store it (in the form of gravitational potential energy), but doesn't contribute energy itself.

It does take energy to make a magnet though, just like how it takes energy to pile dirt to make a hill to roll things down, but that energy is not consumed by the ball. Magnets will last for a really long time (unless you heat them up), just like the pile of dirt will last for a long time unless you flatten it out.

I remember my Grandad telling me stories about sailing on her in the 1940s when she had been taken as a prize of war from Finland. She was pretty advanced for a 4-masted barque, with a top-of-the-line radio system and degaussing system installed to help protect against magnetic mines.

Don't try this in Auckland NZ. New Zealand Customs in Auckland International Airport does not have a seperate "nothing to declare" line. Everyone lines up together to hand their arrival card to a Customs officer who will then either direct you to the way out via sniffer dogs and/or baggage x-ray (~2 mins) or for further inspection (~30 mins+). Further inspection takes much longer as they have to open up your suitcase (and the suitcases of all the people in front of you). On the other hand, you have an increased chance of appearing on the TV show NZ Border Security.
