Though it is located in the asteroid belt, the answer you list for the largest asteroid is not actually an asteroid. It was promoted to dwarf planet status years ago. I suggest you change the question to read: "What is the largest object orbiting within the solar system's asteroid belt?"

No, it actually isn't. Ceres is considerably larger. Vesta doesn't even have a spherical shape (Ceres does). This is because it hasn't reached hidrostatic equilibrium, which indicates it's quite small.

The 'Fancy-shmancy Latin names' you mention make it possible for all nations and languages to have a common scientific names for all people. What use would it be if the official international name for the 'Duodenum' was 'kaksteistsormiksool' and dodekadaktlylos and zwollffingerdarm etc etc ........ nobody would have a clue what they were talking about. Every doctor/scientist in the world understands what the word 'Duodenum' is referring to.

Duodenum is the normal word sifhraven, no-one calls it the "twelve-fingery-intestine" in English. Just to be helpful - I know adverbs don't come naturally to Dutch speakers - where you say "my latin isn't that well", it sounds like it has a cold, or maybe something worse, God forbid. You mean it isn't that good.

Pretty sure there's some element of myth wrapped up in Copernicus. As though he smashed established thought regarding celestial movement, when actually it was generally accepted that the earth was round and went round the sun. Galileo in his war against the church made a lot of brash statements that kind of left a legacy of the church propogating ignorance, but according to the sources I've read, the immanence just doesn't seem to have been there.

There seems to be no source calling him Mikołaj Kopernik during his lifetime. He was spelled Niclas Koppernigk, Nicolaus Kopperlingk, Nicolaus Copernik, Nicolaus Cop(p)ernicus, Nicolaus Coppernic(k), Nicolaus Coppernig, Nicolaj Copphernicj. Fixed spelling wasn't a thing back then. See here and here.

Aristarchus of Samos was an ancient Greek scholar that first wrote about the earth and planets going round the sun. Copernicus in his notes to be published gave credence to Aristarchus as the first. Copernicus' editors convinced him to cross out any reference to Aristarchus and his claim to be the first made him famous.

Science journalism makes me mad. The headline to that article is garbage. If you read the article, you'll see that those materials are "predicted" to be harder than diamond, but it can't be tested because they are so incredibly rare. Diamond is still the correct answer until someone proves otherwise.

https://en.wikipedia.org/wiki/Superhard_material

"Diamond is the hardest known material to date"

I knew about lonsdaleite, but I didn't know there was a man-made version with, ideally, similar hardness. Lonsdaleite has a hexagonal prism-like lattice, instead of a cube-like lattice in a diamond, making it presumably as much as 1.6x harder. However, as QM pointed out, it's rare. Naturally occurring lonsdaleite has only been found in impact craters, created by the intense pressure. Not even the true color is known, because sample sizes are so small.

"Lonsdaleite has never been obtained in samples large enough to test its true hardness (or to evaluate its true color, which remains uncertain). But mathematical models of lonsdaleite’s structure indicate that the substance could be up to 58 percent harder than cubic diamond." That's where this number of 58% harder comes from, theoretical testing.

It's an unfortunately worded question which only biologists would really understand. The brain doesn't have the capacity to break down glycogen, use proteins or lipids for energy production. The rest of the body can do this by inserting various metabolites from breaking these down, into the Krebs or citric acid cycle. The brain relies upon the rest of the body to supply it with glucose from food or the breakdown of glycogen. Only in very extreme circumstances can it use ketones, and that causes physical damage to the blood brain barrier and the brain itself due to the extensive high levels of ketones in the blood that would enable them to infiltrate the central nervous system. The question is basically asking 'What is typically the only substance the brain can use for energy?'

I've tried, out of curiosity, to answer "H20" (meaning H-twenty) to the water question, and, to my surprise, the answer was considered to be correct. I really think it shouldn't be, since it is inherently wrong. Water molecule doesn't have 20 hydrogen atoms, and if some people don't know that, they should be educated, not kept in their ignorance, by accepting the wrong answer.

Jun 7, 2022
Across the site, many misspellings, common or otherwise, are accepted.

This is a philosophical question--is every quiz also a spelling quiz? Quizmaster seems to believe, within some reasonable limit, that knowing the answer to a question and knowing how to spell the words are separate things. After all, if you were administering an oral trivia quiz, you would receive a correct answer whether you knew how to spell it or not.

It's a judgement call about whether or not a misspelling is "close enough". I'd love to have the option (strict spelling or not) on each quiz, but I imagine that would be an impractical amount of work (for one thing, we'd get into a lot of arguments about what is a valid alternate answer, a valid variant spelling, or a misspelling acceptable under the looser standard; for the second, you'd have to effectively have two sets of answer patterns).

If you're going to accept misspellings at all, I'd favor "grafite", especially for those coming from other tongues.

Maybe a nitpick, but the term "yellow dwarf" is not technically correct. The peak spectral output of the sun is actually in the blue-green range. The sun appears yellow on Earth due to atmospheric scattering. "Dwarf" can be argued, as it is opposed to "giant," but the accepted terminology is "main sequence star." It doesn't really affect the way people guess the answer, thoguh, I suppose.
