Ask Science•In Quantum Electrodynamics, are there really "infinitely many" Feynman Diagrams for electron interactions, or is it more like a ridiculously high number like TREE(3)?English
25·3 months agoThere are infinitely many. But the cool math that Feynman worked out is that infinite diagrams (paths) kinda look random, unless they’re not random (aligned).
When you get enough infinite “randombess” you tend to cancel almost everything out (not actually random but phases that destructively interfere), so what you’re left with (when you “sum all paths”) are solutions that favour a particular direction or phase.
Hey there! Sorry, I got busy with work today.
I was just noticing that you have plenty of replies. I think you seem to have enough to go on with.
If you still need anything, hit a reply to this one and I can give you my 2-cents worth of opinion.
I think for those classic clicky dumb thermostats they should be called thermochaser.
You dial up a temp and that’s pretty much the least likely temp that you’re setting, the f****** think will overshoot panic, u-turn dive back past the set-point hit the breaks u-turn again apply full throttle.
Or perhaps a thermotease. For when you do that fine adjustment to try and make it just barely click then 10 seconds later it’s too hot or cold… so you give it anither tiny tweak thinking you gotta be close but no, it’s miles away from clicking - burning away, quietly mocking you.
First question. Was your router also your modem? As in describe each connection/device from street until you get to your router. (Do you also know your connection type? Some flavour of DSL, HFC, Fiber?)
Sure! Scooters could be lethal!
I’d love to see that normalised to how many of each vehicle type are in use aver the same time.
Initially, I see that and think trucks are less deadly than cars, but according to my brief Google search (https://www.statistiques.developpement-durable.gouv.fr/donnees-sur-le-parc-automobile-francais-au-1er-janvier-2024), there are 5x more cars than trucks, which puts them [trucks] over the top of cars in every category.
I guess that doesn’t really matter to the pedestrian. It still sucks to be killed by either.
This Billy Joel remix needs some work. Though, it still makes more sense than the original.

science•Scientists Reveal a Shocking Solution to The Chicken or Egg ParadoxEnglish
21·1 year agoI hear you and actually subscribe to your magazine. But…
Is your chicken-zero growing inside a chicken egg, or is it growing in a proto-chicken-thingo™ egg? I agree the thing growing will be born as the worlds first chicken and then grow its own eggs but what do we call the egg it’s in?
Is the egg named after the thing it hatches? Or, is the egg named after the thing that made the egg? Which might be the same as asking, is it called a “chicken egg” or “chicken’s egg” … or… both?
I guess I’ll need to actually read the research paper to find out.
I ended up on Piwigo. It’s pretty fully featured and allows you to set up access controls for groups. Also has client apps.
And every one of them hatched from a happy little lawn grub that ate our lawn.
I don’t really understand this reply and why this is a shower thought.
But, I take it back. Clearly not a pastor or sermon. Sorry, my bad…

Is this one of those “how do you do fellow kids” accounts made by a very young looking , middle aged pastor attempting to infiltrate social media?

Espresso@infosec.pub•Breville/Sage Touch Impress cleaning (backflush) cycleEnglish
2·2 years agoGood to know. But, so far we haven’t got DRMed cleaning tablets. So, when it asks to clean, throw in some random powder, push the button and let it do whatever it wants. I can’t see how they’ll ever know.
It pisses me off. Because I’d happily buy manufacturer brand consumables if they weren’t such scumbag assholes with their pricing. I might even consider a small premium if the product is decent but not 400% premium just because it matches their brand.
These assholes package up the same common salt-shaker-garden-variety-chemicals costing 1-2 cents per dose (which generic brands charge 10-20c / dose) and sell it for $1 a dose. Screw that.
Anyways. Fight the power. :) Good luck.

Espresso@infosec.pub•Breville/Sage Touch Impress cleaning (backflush) cycleEnglish
3·2 years agoYeah you are a bit but manufacturers do like to ham up the warnings, so it’s understandable.
I wouldn’t stress. They’re all so similar. The variations will need mostly proprietary differentiation nonsense.
The sodium carbonate might attack copper and aluminium at moderate concentrations. I suspect the concentration would be enough to do mild damage if you left it a long time (ever run an aluminium pot, ice cream scoop or kitchen gadget through a dishwasher? You get that crazed grey look). But the chemicals and the duration of the cleaning cycle wouldn’t give it enough time to do meaningful damage.
From a heath angle, the cleaning agents in these tablets are also reasonably mild (in the scheme of things). Probably better to err in the side of no serious chemical burns to customers’ throats (in case the cleaning cycle goes wrong). Sodium carbonate (washing soda) and sodium percarbonate are generally mild irritants - best if you don’t stick your eyeballs on genitals in a concentrate solution.
But they’re not particularly nasty compared to things like dishwasher tablets.
You’d detect the taste before you’d have issues.

4·2 years agoYou can find the general compositions of the powders and tablets from the safety data sheets here: https://www.cafetto.com/safety-data-sheets
I managed to find a Breville SDS to compare (https://s3-ap-southeast-2.amazonaws.com/wc-prod-pim/Asset_Documents/Breville Eco Coffee Residue Cleaning Tablet SDS.pdf)
But from what I’ve seen, they’re all pretty much the same - Washing soda and an oxygen bleach (some brands add surfactants).
If you did it by approximate weight you’d be fine. But double dose probably wouldn’t make a difference either (the ingredients are easily dissolved).
I’d suspect the tablets contain a binder that might make them slower to dissolve.
If you want to get experimental, couch a spoon in one glass and a tablet in another and fill hald with hot water and see how long they take to dissolve.
I’m curious, but probably wouldn’t be curious enough to do it. I’d just Chuck in the scoop and give it a wash cycle and maybe an additional rinse (wash without powder) until the final rinse water from the clean cycle looks clear and tastes ok.
After a rinse or two I can’t imagine it’d be concentrated enough to case an issue from a tiny taste test (but I’m not a doctor, you do you).
