this is actually why i like fahrenheit the most... 0F is "really cold" and 100F is "really hot", whereas in celsius 0C is "kind of cold" and 100C is "uninhabitable". it makes sense for the 0-100 range to be reserved for temperatures frequently encountered in our habitat as humans i think...
That’s a biased view that leads to a scale only convenient for people living in particular latitudes. Now talk to someone living near the equator like Singapore, and 0F is unimaginably cold (even 40F is basically unheard of), and 100F is very hot but not extraordinarily so. Then you talk to someone living close to the arctic and the converse is true. All this talk about 0F to 100F being frequently encountered probabl…

#132NIST Cigarettes are a mere $204 per carton. Depending on what state you live in, that's not bad these days. https://shop.nist.gov/ccrz__ProductDetails?sku=1196a&cclcl=e...
Shows $508 for 2 cartons, so 254 per. NY has probably most expensive smokes, ranging $140-155 per carton

That’s 02025 thinking.
X̅ ? (I'm a little sad the five-digit date hasn't become popular.)
Years aren’t even four digits by custom: they’re just numbers, with the present idiosyncrasy of eschewing a grouping (thousands) separator. We say the sack of Rome was in 410, not 0410. Only for specific serialisation purposes have we ever recorded fixed-width dates, acknowledging that there are limits to this. The recording of two-digit or offset-by-1900 years in computer systems was a case of bad judgement. The recording of four-digit years as is presently customary is pragmatic and entirely adequate for the next few thousand years, and there’s no point in designing things beyond that horizon.

Truth. I once paid nearly $500 for a set of 17 certified, calibrated wooden pencils, with documentation showing that each one met their rated hardness levels of 9H thru 6B. And for $500, they don't even come with erasers, that is an added-cost option. https://www.gardco.com/product/pencil-hardness-test-kit-astm...
I'd like to ask a more specific question than my sibling's excellent "Wait, why?" question :) Why offer erasers on these things? The procedure described below has nothing to do with using these as pencils, and at $500 for a pack I can't imagine anyone, anywhere casually drawing with these. (Is there another procedure, similar to the one described below, except instead of dragging the pencil tip across a surface you d…

Makes me want to go to the ocean and start filtering out water somehow.
You can centrifuge it. Heavier molecules move closer to the bottom. Repeat until you reach the desired purity. You need shitloads of ordinary water to extract a liter of heavy water. And I'd be surprised if there's any superheavy water in that, because tritium radioactively decays. Fun fact: Heavy water is slightly toxic to humans. If you only drank heavy water, you'd die as it shifts the chemical reactions in your b…

Unless you're actually measuring something with any importance, a gallon is about 4 liters. More closely 3.78541... But saying a quart and a liter are about equal is often good enough.
As long as you also know a gallon is 4.0… quarts

How much volume is that for the rest of the world? Really unscientific article.
Just think of the largest container of ranch dressing that you’ve ever seen in a grocery store. It’s that much.

To be honest, if you live outside of the US the answer to that is more likely to be a liter (or less) than a gallon.

> 0F is cold, 100F is hot. I experience both of these temperatures outside where I live every year. Most people never experience anywhere near 0F in their lives. > -20C to -40C seems much more arbitrary as a way to measure the zone humans mostly live in. The zone most humans live in does not routinely (if ever) get anywhere near -20, to say nothing of -40.
The -40C was a typo, should have been 40C, to mirror the 0F to 100F, rounding a bit to make it less silly. It’s been fixed now. Millions do experience 0F, and it’s ok to not use the full range. At or around 0F is cold, as you move closer or beyond it, it’s cold. As you move closer to or beyond 100F, it’s hot. Most people would likely prefer to never deal with 100F.
That’s not even an argument. Billions never experience freezing temperatures let alone 0F, and it’s ok to use negative numbers.
> At or around 0F is cold, as you move closer or beyond it, it’s cold.
The exact same statement can be made about 0C. Hell if you live in a subtropical area 10C is cold.
> Most people would likely prefer to never deal with 100F.
Most people would likely prefer to never deal with 30C.
