worth pointing out, as the laws of thermodynamics are commonly used (incorrectly) by Creationists due to them not understanding this caveat.

Well i would say that the question is correct. The total entropy in the universe never decreases (because we assume the universe is a closed system). So the sum of all entropy never decreases.

An instance of pedantry, i feel, would be the correction of the second law of thermodynamics, which i think closed system expresses as well as isolated system. Pedantic most simply expressed is the need to correct minor mistakes, of questionable significance. Expressing the ease with which you did the quiz might be appear arrogant or hubristic, perhaps even disdainful of these peons who found it more of a challenge. Personally, i found it to be well weighted and moderately challenging; good quiz.

Mhm, very informative, thank you, I guess the word "pedante" in Spanish doesn't literally translate to pedantic in English, will bear it in mind next time.

A tad more leeway on the spelling of palaeontology would be nice. As would me knowing Phylum was spelt with a "Ph" and not an "F". Doh!

We aren't Homo Sapiens because there are a lot of us. Each one of us is still a Homo Sapiens. The word is Sapiens, and the 's' is integral to the word. And in fact I can't imagine anybody who knows the answer isn't going to type Sapiens.

Technically, should be homosapian-sapian, if i was being pedantic :P

I disagree with the 'theory' question. A theory usually is wider than a single verified hypothesis, that can at best be the core of it. And conversely, something can become a theory while its core hypotheses still need further testing and confirmation.

At the risk of being accused of pedantry, could I ask for Tera to be accepted as alternative to Giga in the "billion" question? The American billlion is a thousand million. The British one follows the original French billion (though the French have now changed) which is a million million. Even though the BBC decided a few decades ago to "capitulate" and use the American billion, that is still not universally accepted in UK.
