But having industrial quantities is like most of the argument for using metric! You mean to tell me you’re not converting between kL and mL all the time and reaping the benefits of being able to just slide the decimal over? That’s a shame. I’m not sure that doing your everyday cooking in increments of 125g is all that useful then. The cup is sounding better and better.
We have the same measuring cups I’m sure you use for liquids. They have mL on one side, cups on the other and a scale for sub-sizes. We do have individually-sized scoops which are nice for over-scooping and just sliding your finger across the top to push off the excess and get the amount you need. It’s not strictly necessary though. They come in a set where each smaller scoop fits inside the larger ones in a tight stack that can sit in a drawer.
The infinite granularity is ultimately unnecessary. Recipes don’t call for 0.397 cups. I’m sure you don’t see any that ask for 438 grams. If you do the math on a lot of recipes listed in both metric and imperial, you’ll find that they’re not even using the exact same amounts. The convenience of using standard measures tends to outweigh the flavor difference with plus or minus a percent of ingredient.
You guys have to weigh your flour? We just grab a cup and scoop it and then dump it in the bowl. You’re busting out the scale? You’re not exactly selling me on metric here.
Well then you’ve lost the whole advantage of base 10. You’re buying 2L or 4L containers and dividing them up into 250ml increments, having to do divisions of 8 or 16 like some common imperial peasant, only you’re doing it with numbers that have no real relationship with your daily life. I mean, ultimately it’s all arbitrary anyway. But when someone says use 2 cups, that’s 2 scoops, which seems better to me than having to know that 500ml is 2 scoops.
A useful size to package and sell ingredients in, such that the person following a recipe can halve or double the recipe as needed and still use the entire package with no waste.
Would it help if I told you that it was defined as the volume contained in a cube whose length is the distance light travels in a vacuum in 1/166219513th of a second? I imagine it wouldn’t. Obviously the litre is superior, it’s a much less arbitrary cube defined by the distance light travels in a vacuum in 1/2997924580 seconds.
The whole point of cups is that you can buy an ingredient by the gallon and it’s very likely that you can double or halve the recipe to your heart’s content and eventually use up the entire package with no waste.
The observable universe is constantly expanding as the passage of time allows light to reach us from more and more distant parts of the universe. So it’s less “we don’t know what’s outside” and more like (to a certain extent) “we have to wait and see.” And there’s nothing we’ve seen to indicate that these external regions that are being revealed are anything but more of the same kinds of things in our inner region of the observable universe.
The important thing in the balloon analogy isn’t what the balloon is expanding into, it’s just that every point on the balloon is drifting away from every other point.
One thing to consider, though, is that space may not even be a real physical thing. Maybe location is just a property of things, like mass or electrical charge. It could just be an inherent value that adjusts and influences other things according to the laws of physics. Maybe it’s less that “space is expanding” and just that “the location property of everything is constantly diverging.” There’s no need to worry about what anything is expanding into because our conception of space may just be a mental construct.
I would think you’d have to instantaneously accelerate because incremental acceleration doesn’t work the way we typically think it does at high speeds.
If you’re moving at 99.999% the speed of light relative to Earth, anything close to your speed is going to be moving quite slowly relative to you. When you accelerate some more, the change in speed relative to those close things is much larger than the change in speed you experience relative to Earth (it gets smaller and smaller as you approach light speed). But as far as I understand, there’s no such thing as moving at light speed relative to Earth but not relative to other sub-light speed things. You’d have to instantaneously move at light speed relative to everything (every sub-light speed thing).
Ooh, great one. Here are my picks for each panel:
Well, famously, they’re waves and particles. The double slit which way experiment will only set off the detector in one slit, as if it was a particle. Yet, without a detector it will interfere with itself as if it were a wave that passed through both slits.
You’re right. But the thing that’s interesting about the double slit experiment though is that it works on only a single photon. It’s as if all the traffic was created by a single car. So classically you might not think that the single car should care if the freight truck is heading down a different lane than the car but in QM it does, because the car is in a superposition of occupying several lanes.
I’m probably driving the analogy straight into the ground of course
What are you trying to see exactly? There’s this video done with polarizers: https://youtu.be/unCXuRXpEhs Of course, it’s not an instant on/off but having an instant on/off doesn’t really change anything.
Wikipedia has a whole list of citations on this very sentence lol.
There is near unanimous consensus among economists that tariffs are self-defeating and have a negative effect on economic growth and economic welfare
Tariffs are a net negative. Always. The things produced will not be competitive on the global market, if they were, we’d already be making them. The higher prices always destroy more jobs than they create. Retaliatory tariffs destroy even more jobs. The higher prices drive down demand and make the working class consumer poorer. Always.
There’s no economic upside to tariffs, over any time horizon. They create a small number of jobs in a specific sector at a very expensive cost. Some politicians might decide that the enormous economic cost is worth it for other reasons, but a net positive they are not.
Because the uncertainty in the measurement is related to the wavelength of a photon used to make the measurement and smaller wavelengths (higher frequencies) lower that uncertainty but are more energetic.
PBS Spacetime has an excellent video on this very subject.
To accurately measure the size or location of something requires energy. The more precise the measurement, the more energy is required. The amount of energy required get the precision below the Planck length would literally create a black hole.
Not American enough. I need it in football fields.
My place of work has a pretty high rate of pronoun signaling and I’ve found it immensely useful. Not just for the usual androgynous names line Pat or Elliott, but also I work with people all around the world, how would you refer to Jung Bae? Judging by the number of foreign people who have never seen my name, I imagine it goes both ways. And, yes, I also work with a number of nonbinary and trans people so of course it helps there too.
Some people refer to everybody, even those they know, as they/them and I honestly kinda like it. Been considering taking that habit on myself.
Our recipes rarely use weights except for maybe meats. We’ve got a scale in my kitchen but it hasn’t been touched in a while.
The ratios of ingredients matter more than the exact values so for the recipe you’re talking about, it’d be like 2 cups of milk, 1 cup flour, 1/4 cup of oil, 1/8 cup of sugar (or 2 tablespoons, which is a pretty common size so most people probably have a scoop for that).
