5 questions you had better know the answer to...
...if you want me to take you seriously as a scientist. This if from an article in the Guardian, about scientific illiteracy. Here are the questions:
Q: Why does salt dissolve in water?
Q: Roughly how old is the earth?
Q: What happens when you turn on a light?
Q: Is a clone the same as a twin?
Q: Why is the sky blue?
Q: What is the Second Law of Thermodynamics?
Now, I say 5 questions because that last one is totally bogus. You could have been very good at science for years and completely understand the basics of thermodynamics yet not remember which law is which.
I have no problem answering all these questions (in fact, the very article described above does a piss-poor job of answering some of them [and they are wrong about the twin one!]), but anyone who works in science should really have some kind of understanding of what the right answer is to each of these.
At the very least your answer better be better than some of the people they interviewed for this article (on ions):
Kirsty Wark Because it's less dense.
Daisy Goodwin It forms
another compound. The only reason I know any of this
is because I've been
testing my daughter on her GCSEs.
Uh, your daughter is failing! But hey, Daisy Goodwin works on poetry anthologies and Kirsty Wark is a newscaster. Check out the reply of Robert Winston, who is a "Human fertility expert and science TV presenter" (a former medical researcher):
It's to do with ions isn't it? Let me just work it out. It's to do with the way
sodium and chloride ions, um. Do you know, I'm not sure I can really explain it.
I can't remember now from my physics years ago.
Yeah, you work on biology. Even more, you work on physiology (of a particular organism). You're telling me you don't understand how water dissolves things? You do realize that your organism of study is 80-odd percent water?
How about these replies:
(Age of the earth)
Susan Greenfield Oh blimey. Well, I know that human beings have been going for
about a million and a half years, so ... I'm just grasping here. Something like
60 billion years or something like that, but that's a grasp. I'm not a physical
scientist and it shows. I'm probably not scientifically literate.
(why is the sky blue)
Seriously? People don't know this stuff? And John, your child is probably failing too.John O'Farrell My daughter explained this to me the other day. She is in
Year Seven. It's to do with blue being the dominant colour in the colour
spectrum.
Kirsty Wark Because it's a reflection of the oceans on the planet. No idea
apart from that. I think the sky is blue because... the rain clouds obscure the blue, and the blue is a reflection... because of the sunshine. Fuck! I don't know! Why is the sky blue?Ok, first of all. My friend M and his wife L (and their baby C) got me what is, to this point, pretty much the most amazing baby gift we have recieved. Little Alton has a shirt that contains the answer to the question: "Why is the sky blue?" courtesy of M, L, and C (have I sent you guys a thank you yet? Gosh, I hope so! THANK YOU!!). I'll admit, as I have previously, that this is exactly the kind of question that I'm worried could throw me off my guard when my own child is asking me for the first time. However, these people are being asked by an adult, given some time to think, and that's the best they could come up with? Reflection off the ocean? I've lived in Kansas, and I can assure you the sky is blue there.
Secondly, I hate to hold people up to ridicule, but this is exactly what is wrong with western civilization and, indeed, the world. We are all idiots. 90% of people I've met in my life only know how to do a handful of things. Even 'jack-of-all-trades' people who do mechanical odd-jobs often don't seem to have the faintest clue why something works. Scientists seem to be among the majority here. Are we really being served well in society by producing engineers that can't understand any biology? Or biologists who literally can't do 1st year calculus?
Anyway, it is late and I'm tired and a little intoxicated so I should probably stop here. But seriously, from now on, if you can't answer basic questions about the world, then I'm not counting you as a real scientist.
