Yes, but ... the Imperial system? Really? Grown adults shouldn't have to look up how Imperial measurements convert to one another within the same system while cooking or whatever. It's objectively dumb.
I think Celsius is similarly more logical -- freezing and boiling are great, logical points on the line -- but the fewer degrees in the human-comfortable range of the scale means it's less precise for day to day usage, IMO. If water boiled at 500 degrees or so, there'd be no question that it's the right way to go.
That's actually my
'yeah... wait, no, not-yeah' moment for Metric vs. Imperial discussions.
1) Not having to figure out how many tablespoons are in a cup (because instead you are using metric where volumes are just multiples of ten): point for metric. 2) Putting trim around your room and having one side be three feet, four and seven eights inches long, the other four feet, five and three-quarters inches long, and having to figure out how long to cut an third piece to finish off your eleven foot, three and seven sixteenths inch long room (because instead you are using metric and you just add all the two base-ten numbers together and subtract from the third to get the remaining necessary length): points for metric. 3) Water (pure, at sea-level) transitioning from solid to liquid at 0 and liquid to gas at 100:
no score drawn. It doesn't actually benefit anything (except making two very specific maybe-important -in-everyday-life physical qualities be readily memorable). You don't multiply temperatures. The one example I can think of where you multiply
by a temperature (as opposed to a delta of temperature), the ideal gas law (pV=nRT), requires you to use absolute temperature. Both Celsius and Fahrenheit use base-ten partial-state nomenclature, sure adding and subtracting temperatures works the same for both. The 0 and 100 stop being relevant* the instant you are boiling water in Denver or the sea-level water is sea water or you care about whether your kid with the flu is running a fever instead of literally boiling or freezing. Of all the distinctions between Metric and Imperial, this one come closest to being arbitrary and of no objective benefit over an alternative.
*not that there was a lot of mathematical benefit to these being 0 and 100, it just helps in remembering them
It depends entirely on the event. Most people can't remember what they had for breakfast yesterday but can tell you exactly where they were when some historically significant event occurred. For example, I was in class watching the Berlin Wall come down on 9 November 1989. Likewise, when the Challenger exploded on 18 January 1986, I was watching live, like most US schoolchildren at the time. On 9/11 I was taking mass transit to work and had no idea what was going on until I got to work and heard people talking. I got to the break room just in time to watch the second plane fly into the tower. It also depends entirely on what bits of information are being recalled and how relevant they are in context.
I remember the Challenger explosion. I was home sick from middle school that day, and watching on a B&W TV in my bedroom. It was frustrating because I saw it happen, kind of understood what was happening, but had no one to turn to ask about, help process it, or really understand all the ramifications (or be distracted, or whatever the teachers did for the rest of the US schoolchildren). It was horrifying. It also isn't what happened. I was in school that day, and like 38.7 of the 41.2 million children in grade-through-high school children in 1986, wasn't watching it (it was only ~2.5 million of US schoolchildren who were watching at the time). That memory of watching it while home sick -- that happened to my friend Mike. I heard it, internalized it, and now thoroughly have it lodged in my brain as something that happened to me. This frighteningly common experience is why people question later accounts of events, as Snarf is discussing.
But they are affected by literally all other types of bias and inaccuracy. Snarf seems to be suggesting that they are free of bias and inaccuracy by the mere fact of being written down close to the event. That's absolutely not how anything works. Take just about any two newspapers from the same day reporting on the same event and you can read wildly different stories. Doubly so with any kind of political event and political papers.
This, however, is also true. Something being contemporaneous does not prevent something from being biased.
There's also the issue that not everything is written down. Not everything is communicated in the first place, either. A primary documentation only standard is going to have more gaps in the evidentiary trail of things. Sometimes the things that show up in the primary documentation are going to be biased not because of innate quality of the observer (like the political bias example), but merely based on what was recorded (financial records might tell what transactions took place, but the causes or motivations might have been conveyed verbally or not at all).
History is messy, and you have to take all look at all contributing evidence and recognize not just how it might be biased, but why what it is and isn't/could or could not show/etc.
Unpopular opinion- while experts can be wrong, you are not an expert just because you have access to the internet and the ability to google things.
Everyone overestimates their own abilities, so while experts can be wrong, it is almost always the case that you will be wronger.
Experts can be wrong. People who think they are experts can be wrong. People who think the other person in a discussion must merely have access to the internet as their supposed expertise regarding a situation can be wrong (about that, or the topic being discussed). People can take knowledge from experts and interpret it (either the expertise in total or the individual knowledge communicated) and apply it to situations it doesn't actually apply. This is why, in general, I look for people providing both the (checkable) references in question, as well as the actual functional argument for what said evidence is, how it applies, and what they believe it implies about the topic being discussed. There's no shortcut to bringing one's receipts.
