20 out of 20. Question number 10 has a questionably correct answer. Viruses are considered to be living things by many who study in that field. otherwise, great quiz

[@quiznook]

Thank you for the precision. I looked at so many sources to confirm/infirm that fact! I'll watch out for next time when the line is this blurry 😅 Thanks again for playing and for your comment 👍🤗

[@jillianbakke2567]

@@quiznook no problem. I did graduate studies in biochemistry and microbiology, so I probably have a slightly more nuanced view, I guess you could say. In any case it was a very very good quiz and I really enjoyed it. Keep up the good work so many quizzes online are just not that great your s certainly was however.

[@quiznook]

Thank you thank you, your comment is greatly appreciated. I’m glad you enjoy the quizzes, and I definitely plan on making more :) Cheers!

[@maudeboggins9834]

Goodness well done, what school did you go to? I can remember chemistry was the last 2 periods on a Friday. I was bored out of my brain.

[@jillianbakke2567]

@@maudeboggins9834 I graduated from Michigan State University, home of one of the best basketball players of all time, magic Johnson. I absolutely loved chemistry and biochemistry. It's all the fault of Isaac Asimov and his book The world of carbon. I read that when I was 10 or 11 and I was determined to be a biochemist like him.

[@drdan75]

19 out of 20. The only question I missed was the one about the study of dreams.

[@buddyjenkins7188]

That's the one I missed. Is that a real science?

[@rickkwitkoski1976]

@@buddyjenkins7188 Yeah, you can study it, scientifically. Just don't attempt to make predictions about what the dreams might "mean"! I didn't know that name either.

[@marcderiveau9307]

Me too, and 19 others.

Me too. Same one

[@rg1809]

Yes. I didn't know the answer and like most who missed it, I went to somnulant as a possible root.

[@benji-L]

17/20. Minor quibble: the Turing Test does not test for human-like thinking (as stated in the question), but human-like behavior (as stated in the answer). I couldn't begin to design a test to measure human-like thinking. More specifically, are the computer's responses to questions indistinguishable from those of a human.

[@pelimies1818]

Lol, the first picture presents two electrons of different size and colour. That is a maximum fail.

[@robertloveless4938]

Makes for a wobbly atom- like a poorly loaded washing machine. ;-)

[@md65000]

You have to specify the temperature and pressure before you can say if neon is a gas or a liquid.

[@rickkwitkoski1976]

Yeah, THAT was a crap question. And besides, IN a neon tube, it is not a gas either, it is a PLASMA!

[@ThomasEWalker]

O barf. In the absence of specs it's gotta be thought of as 'room temperature' at sea level.

[@mayorb3366]

This one was unusual for me. I either knew the answer outright, or had no idea. Got 16.

[@Jerryed10]

I would not consider the image in Number 1 to be correct for any model of the atom.

[@keithmills778]

That’s because you’re not 150 years old. When Rutherford discovered that the atom was largely empty space (1909), different models arose to explain this phenomenon. One looked kinda like the image in Question 1. Since the neutron wasn’t discovered until 1932, early atomic models consisted of a proton core with electrons whizzing around it. Neils Bohr came up with the idea of electrons travelling in specific orbits in 1911, making his concept of the atom look like a tiny solar system.

[@oobrocks]

U are wrong

[@verucasalt2391]

⁠@@keithmills778You most likely know more about this than I, but while studying radiation, that image was Nils Bohr’s theory of the atom.

[@stevearrendale8341]

Of course you wouldn’t

[@NoosaHeads]

Totally agree. That was antiquated 40 years ago.

17/20 dreams, brain weight and #1 (quibble over representation though)

[@quiznook]

Addendum Q4: In the explanation, it should be specified that MRIs emit a type of *non-ionizing* radiation, from strong magnetic field and radio waves (not the same as the ionizing radiation that is found in X-ray and CT imaging). Non-ionizing radiation does not have enough energy to remove electrons from an atom. Microwaves and visible light, for instance, are types of non-ionizing radiation that is present all around us. This clarification does not affect the answer to the question :)

[@kevinireland8020]

flip flop

[@davidlawson4281]

I must confess that I never considered magnetism as a form of radiation. But, your point that it is non ionizing is obviously correct.

[@davidlawson4281]

@@1-Wheel-DriveI am afraid that QUIZNOOK is correct. It is “non ioninizing” radiation.

Several comments: Only those who believe they scored well will report their scores. Therefore, we have no idea of the average score. We also know nothing about the age or education of the test takers. I am an aging retired lawyer who scored 19, missing question 15. School kids with a science background might do better.

Great quiz

[@ruatoomey9107]

0 degrees Celsius is 32 degrees Fahrenheit. After that every 1C = 1.8F for 33.8F,or every 5C = 9F for 41F. 10C = 32 +18 for 50F. Works negatively also, -10 C = 32 -18 which is 14F. They are equal at -40. Just easy for kids to understand

[@rickkwitkoski1976]

19/20 - didn't know what the science of "dreaming" was called This is junior high school stuff. #1. WTF kind of representation of an atom is THAT? What are the two large circles on the outside? Electrons? Then what about the electrons on the other orbitals? BAD! #4. It is actually Nuclear Magnetic Resonance Imaging! It is just that the word "nuclear" scares people so they took it out. #6. Oneirology - Ok, I'll try to remember that one. #7. Actually, WITHIN a neon tube, the neon is a PLASMA and not a gas. AND at cold enough temps it can be a liquid or a solid too! Bad question! #10. Virus... yeah. Debatable as to whether they are actually "alive" or not. #15. Phagocytosis - NOT JUST the immune system! Anytime a cell "eats" another cell. I'll try some of your other quizzes now...

For your "which is a gas" question you need to state "at standard temperature and pressure". Nothing is a gas if the temperature is low enough.

#12 Another interesting fact to convert 1 bar (the imperial measurement) to Pascals (the metric one) simply multiply by 10,000. Weird, considering every other unit differs hugely.

[@JohnRandomness105]

10,000? Or 100,100? I thought that a bar was just a notch under an atm, which is 101,300 Pa.

[@JohnRandomness105]

@abigmonkeyforme Sorry, the extra 1 in the number was a typo.

[@rickkwitkoski1976]

bar... for AIR pressure! For the pressure of other things, like pneumatic tires, PSI is used. If you SCUBA dive, then you might see your cylinder pressure as PSI - usually about 3000. OR you might see it as BAR - usually about 200.

[@ReuvenF957]

18 out of 20. Missing the one on the science of dreams and one other (obviously). Just because we're scientists doesn't mean we can't speak proper English. Question 20 should be worded "WHOSE theory is..." and not 'Which'. Alternatively, the answers should be changed from proper names to pronouns. For example, "Pythagorean".

[@trainliker100]

18/20. I thought it was mildly challenging. The 2 I missed (name for the study of sleep and the phagocytosis question) had me having to just guess or maybe able to eliminate only 1 of the four answers. Had not heard of either term before.

#14 Here's a thought, what if we haven't detected a transmission from a single alien civilisation, because there are loads? For example, you are standing on the centre spot of a soccer pitch just before a big game, can you hear the voice of a single fan above all the others?

If that was the case we would be hearing a stadium of aliens but just unable to pick one out. So far Drakes equation is not looking very good.
