Grrrr, Jane Goodall! I had Dian Fossey stuck in my head and couldn't remember the other primate lady. LOL

Half the population is composed of primate ladies...

Not quite - According to the CIA World Factbook, the 2013 estimate of total world population ratios is 1.01 male to every 1.0 female.

Well, only half of the PRIMATE population ;-)

Except that you would get Mendel by typing in Mendeleev, so it seems superfluous to have both.

Thank you for mentioning the 2 scientists left off this list! That must have been some mistake, I'm sure they'll get right on updating this so that it's comprehensive.

aaaagh, I spent the whole quiz trying to remember Fleming and I couldn't remember it. And his discovery saved more lives than all of these other scientists put together!

Actually Tesla was the maker of the X-Ray

Roentgen discovered X-Rays during an experiment where he was testing whether cathode rays could pass through glass.

Level 74
Feb 16, 2022
The Captain's not entirely wrong. Tesla noticed an effect caused by x-rays while he was photographing Mark Twain a year before Roentgen's discovery and study of x-rays. It was a ghost image of a screw in his camera's lens that shouldn't have been visible, if I recall correctly. That's all Tesla did, though, he certainly wasn't the "maker of the x-ray".

Abu Ali al-Hasan ibn al-Haytham al-Hasan of Basra. 10th Century Arab mathematician considered to be the father of optics and one of the earliest proponents of what is now known as the scientific method.

Would've been cool to see him show up on this one.

Nice to see a few that usually arent in other famous scientist quizes. like davinci, tesla, pavlov, volta. (and that the davinci clue wasnt made supereasy, you either know it or you dont with this clue) But very surprised at how low the average is. The average score is 10!! (I have done many quizes by now, some much harder and usually the average isnt this low)

Are you sure that Antoine Lavoisier was the father of modern chemistry? What is "modern" chemistry anyway? I thought of several others who might deserve the title: Haber, Leo Baekeland, Percy Lavon Julian, Nobel, Pauling, etc.

Isn't Euler more of a mathematician rather than a scientist? Same goes with Euclid and Archimedes (though my knowledge is not big when it comes to the ancient Greeks)?
+3
Level 68
Feb 15, 2020
Euler was also a mathematician, but he was a first class scientist who made lots of contributions to physics and astronomy especially. In Euler's time, it didn't really make sense to make a distinction between math and science. That's also true for the ancient philosophers/mathematicians/scientists. One might argue that it still doesn't make sense today.

My trivial correction: the word "considered" actually has 2 e's in it (but not in your Euclidean clue).
+3
Level 63
Feb 18, 2020
Well, mathematics is a form of science. The quiz title may be a bit misleading but in the instructions it says "contributed to science" so they all work imo.

Math isnt science, but but it is its biggest partner
+1
Level 72
Mar 2, 2020
I agree with carry that mathematicians should be included, math is almost a prerequisite for a lot of science and as mentioned a lot of people in history were both. Archimedes discovery was definitely a scientific one, displacement is a scientific concept, not really a mathematical one.

Mathematicians arent scientists, but they sure do contribute to it.

Pavlov didn't actually use a bell - he used a variety of stimuli including a metronome and a buzzer. I suspect the bell fact is so ingrained now that nobody really cares whether it's accurate or not.

Here's the play-by-play:

Me: Electric potential means voltage.

Me: The unit of voltage is the volt.

Me: Volt isn't anybody's name...

Me: Types volt to be sure

Me: Welp, I wonder what they want. Guess I better give up.

My nit: really should say 'evolution by natural selection'. Lots of people had theories about evolution. Darwin proposed a mechanism by which it can take place.

Great quiz. Definitely one of the most frustrating on here. There must have been ten questions where I had the answer in the back of my mind somewhere. “Ohhh that’s ehhhh, aragh…..what’s name…bleep. On to the next question.” And repeat.
