  • P.S. Does anyone know where I could get some metric-only measuring cups?

    The key is to never use measuring cups, stick to the scale for everything. Using recipes made with mass is the best way to do it, but if you are trying to adapt a volume based recipe, look at the serving size on the food package; it should be given in volume and mass. For example my king arthur brand 00 pizza flour serving size is 1/4 cup (30 g).

  • One of my friends had their water hookups backwards, too, and they had no clue until I checked after they complained to me about how all their clothes were shrinking despite only ever washing on cold and hang drying. Sounds like a nice feature to have a sensor in there.

  • I've definitely got a soft spot for any electromechanical appliances. Computers have gotten so cheap that every appliance built now runs on them, but it's much harder (for me, at least) to do anything about it when one stops working.

    • My chest freezer stopped working, and i was able to put in a new relay for $2. The circuit diagram made it easy to diagnose with a multimeter. Oddly enough, i had to buy a 10 pack, so i likewise have a bunch of spares I'll never need.
    • My dishwasher stopped working, and the manual specifically showed which wires to connect to to test resistance of each component to see if anything needed to be replaced. It turned out that the float was gunked up, so it read as having enough water even though it didn't.
    • My fridge ice maker stopped working, and I just had to stick in a jumper wire to put it through a test cycle that immediately made it clear what was going wrong (a short), and i was able to fix it.

    This is all in contrast to my clothes washer that runs on a computer, and it gives me an error message that basically just means "it's not draining right", and there's like 8 potential causes, and I've tried to address them all, but it's still get the error message.

  • I think a major one is to try to avoid trusting in unfounded precision.

    If you want to make lemonade like a chemist, you don't just weigh out some lemon juice and add it to water and sugar. You measure sugar and citric acid content of the batch of lemon juice, then calculate how much water will dilute it to the right pH, and how much sugar will bring it to your desired osmolarity. In reality, no one is going to do that unless they run a business and need a completely repeatable. If you get lazy and just weigh out the same mass of stuff with a new batch of lemon juice, you could be way off. Better to just make it and taste it then adjust. Fruits, vegetables, and meats are not consistent products, so you can't treat them as such.

    If i were to be writing recipes for cooking, I would have fruits/vegetables/meats/eggs listed by quantity, not mass (e.g., 1 onion, 1 egg), but i would include a rough mass to account for regional variations in size (maybe your carrots are twice the size of mine). Spices i would not give amounts for because they are always to taste. At most, I would give ratios (e.g. 50% thyme, 25% oregano). Lots of people have old, preground spices, so they will need to use much more than someone using whole spices freshly ground. I think salt could be given as a percentage of total mass of other ingredients, but desired salinity is a wide range, so i would have to aim low and let people adjust upward.

    Baking is a little different, and I really like cookbooks that use bakers percentages, however, they don't work well for ingredients like egg that I would want to use in discrete increments. For anything with flour, I would specify brand and/or protein level. A European trying to follow an American bread recipe will likely end up disappointed because European flour usually has lower protein (growing conditions are different), which will result in different outcomes.

    I will say in defense of teaspoons, most home cooks have scales that have a 1 gram resolution, though accuracy is questionable if you are only measuring a few grams or less. Teaspoons (and their smaller fractions) are going to be more accurate for those ingredients. Personally, I just have a second, smaller scale with greater resolution.

    One thing that I like experimenting with that i have to search for every time is the time/temperature curves for pasteurization of different foods. Every "knows" you are supposed to cook chicken (and most "prepared foods") to 165 °F according to the FDA/USDA. What most people don't know is that that temperature is what your food needs to hit for 1 second to have the proper reduction of bacteria (e.g., 7-log for chicken, which is a really high bar). You get the same reduction with 15 seconds at 160 °F or an hour at a little over 135 °F. You can easily do that with a sous vide bath.

    It's really cool for people who are immunocomprimised or pregnant because you can cook a steak to medium rare, but hold temp for a couple hours, and it's just as safe as if you cooked it to way hotter and ruined the meat. You can also do runny egg yolks.

    Here's the first link that came up when I looked for it, but I'm sure you could find the actual government publication.

  • Why would you want anything by volume? Mass is so much easier. 50 ml of honey is way more annoying to get into a recipe than dumping it right into whatever container the rest of the ingredients are in while it's sat on a scale.

  • My front loading clothes washer. It frequently doesn't drain right. If you create a fault tree on what causes that, you can have:

    • Faulty water level sensor
    • Clogged water level sensor hose
    • Clogged filter
    • Clog around the heating element
    • Broken check valve
    • Faulty pump
    • Clog between drum and liner
    • Faulty control board

    The pump can clearly be heard running when the water levels are too high, so I know the sensor, sensor hose, controls, check valve, and pump are all functioning. Sometimes, the pump runs for way longer than you'd think necessary, with only a small trickle of water coming out little bit by bit. This indicates to me that there is a clog upstream from the pump. Multiple times, I have squeezed myself back behind the washer to take the back off and access the filter (which should be accessible from the front). I've found no clog there. Ive taken out the heating element to check for clogs around it, and found nothing there. Ive shown a bright light from inside the drum to highlight any potential clogs between it and the drum, and seen nothing there. Despite all of that, the problem remains, and when I manually spin the drum with nothing inside, I can hear what sounds like stuff moving around inside.

    I assume it must be ghosts or something at this point.

  • I found this good review article based on a study commissioned by the Canadian government.

    It seems like potential IQ effects are still difficult to distinguish as a dose response, so they weren't able to come up with a point of departure. It doesn't help that in a lot of studies comparing "high" and "low" fluoridation effects on IQ, the "low" is still higher than the WHO recommended level of 1.5 mg/L, and the US recommended level of 0.75.

    I think the optimal level is likely going to vary by municipality based on the quality of dental care and the use of fluoridated toothpaste (that everyone overuses), and consumption of high fluoride beverages like tea. I guess my main takeaway is that people need to read their local water quality report, and do what they will with that information

  • I think it depends on the type of tourist attraction. In places like beach towns, "locals" are usually people who happened to have enough money to buy a vacation house, and decided to make it permanent. Or think of ski towns where the cost of living is so expensive that everyone who actually works there commutes in from another hour away or lives in their car or a jam packed seasonal rental. Basically anywhere that tourism is the only industry, a lot of decent people will be priced out.

  • One thing to keep in mind with a lot of responses is often when someone says "we didn't learn about x in high school", what they should be saying is "I didn't learn about x in high school". I've certainly heard former classmates claiming not to have learned something even though they were sitting next to me when I learned it.

    When i was a preteen, we learned about WW2, mainly from a US perspective, and had a fairly large focus on the holocaust, including a visit to a holocaust museum.

    As a teen, I had a class on specifically European history. In there, we learned about lot more about the rise of the nazis (though not much on Italian fascists).

    Here's the tl;dr on what I remember learning about then:

    WWI ended with the treaty of Versailles which was not a realistic, sustainable peace. We learned about the economic trouble like hyperinflation. We learned about the beer hall putsch, and that it was effectively unpunished. We learned that Hitler then sought power through legal means by allying with a broad range of groups unhappy with the current government. As he rose to power, various elements were purged from the government. Concurrently, political violence from the stormtroopers suppressed minorities and other enemies from organizing against them. This culminated in Hitler being elected chancellor, and then the enabling act gave him ultimate power. In the night of the long knives, all the allied elements in the party were purged. After that was kristallnacht, the remilitarization of the rhineland, annexation of Austria and the sudetenland, and then finally the invasion of Poland.
