This is a very clunky clue:

When an object moves in the reverse sense of “normal” motion.

Is it possible to re-word it?

Can you suggest an alternate wording? I got the answer right away.

It's the least guessed answer. I would reword it "Planetary motion contrary to the majority of other objects," but I think the current clue should be fine.

I think if you know the word retrograde the clue is indicative.

I hadn’t a clue on that one, but when I saw the answer I wasn’t quite sure how I would have worded it to make it more obvious. As a non physicist that’s not a word I encounter very often. Not that I have a problem with that. If QM wants to change the word it may make it easier for people to get but the quiz is probably set at about the right difficulty level as is.

I agree that this clue isn't exactly accurate. Planets in retrograde are only appearing to move backwards. The only objects that actually move in the 'reverse of normal direction', or backwards, are antiparticles in the Feynman-Stuckelberg interpretation.

Can you accept "solar eclipse"? I only answered it right because I got an E from the quote. After all, a solar eclipse is the precise event the hint suggests.

When I heard Neil Armstrong say it, when I was 13-1/2 years old, I thought he said "That's one small step for man, one giant leap for mankind". I immediately knew what he meant to say, and thought he must have flubbed his line, saying "man" instead of "a man". If you listen to it, you'll hear what I heard.

Good quiz! I will say that Newton wasn't a philosopher, he was a mathematician and a physicist. Back then he would have been called a "natural philosopher" but not today.
+3
Level 71

He actually spent most of his life "studying" alchemy and theology. For the sake of all his other contributions, let's respectfully group these under the term "philosophy", because it feels wrong to say that Newton spent most of his life pursuing crackpot theories on the lunatic fringe.
+2
Level 58
Oct 22, 2024
I think that's (put respectfully) a little bit unfair. We say alchemy is mumbo-jumbo now because we know what substances are made up of and their relationships to each other, but when Newton was around they knew nothing about that, and hadn't got any real distance past theorising. I defy you to prove that you can't make gold out of base metals arguing only with knowledge that existed in Europe in 1700. The first list of chemical elements wasn't written until 1789, and even then it listed light and calorique as two of them.

And as for theology, the same applies, with the difference that nothing has been discovered between 1700 and now to make it crackpot or put it on any lunatic fringe.

"First name of the philosopher that defined the Theory of Gravity" - the correct answer must be Plutarch. Isaac Newton was not a philosopher, and his "definition" of gravity was likely plagiarized from Robert Hooke's papers on universal gravitation from 4 or 5 years prior. Not to mention that the word "gravity" in regard to universal attraction to the Earth was in use in the English language for hundreds of years before Newton, borrowed from Latin, who likely borrowed the idea from Plutarch, simply eschewing the original Greek term for it in favour of a Latin term.

If you want to stick with the answer, maybe "first name of 'the father of classical mechanics'" or, even better IMO, "the first name of the inventor of the reflecting telescope."

+1
Level 83

Firstly, "philosophy" back then was a very general term that incorporated what we now know as the sciences. Secondly, Newton wasn't just plagiarising willy-nilly, his most famous quote after all was "If I have seen further, it is by standing on the shoulders of giants".

ideas:

"interstellar" is not the full term. the term is "interstellar space", however that seems a bit long. jupiter has a moon named io.

"artemis" should also be accepted for the nasa lunar program. i think nasa is working on artemis right now, and their goal is to send a person to the moon again. and it also starts with A.

other than that good quiz got 19/23
