1. B. Light. It comes from the Latin word "celeritas" meaning swiftness.
2. B. The astronomical unit is a unit of length approximately equal to the distance from the Earth to the Sun. The currently accepted value of the AU is 149,597,870,691 +/- 30 metres (nearly 150 million kilometres or 93 million miles).
3. A. 299,792,458 meters per second or 186,282.397 miles per second.
4. C. The earth passes between the sun and the moon.
5. B. Parallax.
6. A. H(b,a,c). In Logic, sentences (that is declarative sentences, also variously called propositions or statements) are those strings of words or symbols which are either true or false, i.e. are truthbearers.
7. B. Absolute zero.
8. C. 94
9. B. The gravitational force is weakest because even though it's effects can be felt over great distances, it is relatively the easiest of the four to overcome.
10. D. Beta wave, or beta rhythm, is the term used to designate the frequency range of brain activity above 12 Hz (12 transitions or cycles per second).
11. C. Diophantine equation. In mathematics, a Diophantine equation is an indeterminate polynomial equation that allows the variables to be integers only.
12. D. Integral equation. In mathematics, an integral equation is an equation in which an unknown function appears under an integral sign.
13. B. The game theory.
14. A. Aphasia.
15. B. Glossolalia. Glossolalia is a well documented phenomenon closely associated with religious practice. It is also known as, "speaking in tongue".
16. A. Quadratic reciprosity and Pythagoras' Theorem are known to have more proofs than any other theorems but it is uncertain which of the two has the most.
17. D. Cake decorating. I had to slip that one in on behalf of a very special person who is absolutely an expert at this art. The Lambeth Method uses intricate dimensional overpiping of borders on a fondant covered cake. The Australian Method also uses intricate royal icing piping over fondant-covered cakes, but then adds delicate lacework and detailed extension and curtain work.
18. A. Rappelling. The process of descending on a fixed rope. NOTE: There is actually a style of rappelling called Australian.
19. B. Swiss seat. The swiss seat is a rope tying technique that can be used as a substitute for a climbing harness.
20. D. The largest denomination ever printed by the U.S. government was the $100,000.00 note. It was used only for transactions between government agencies. The note is still technically considered legal tender.
21. C. The likeness of Woodrow Wilson, the 28th President of the U.S. is on the note.

This test does not belong on OkCupid unless you want to become a bit less lazy and actually grade the thing and give people their approximate score.
Also, in 16, claiming that both theorems have more proofs than each other is absolutely absurd.
After doing a google search of this I found that this is indeed correct. Several web sites on math recognized these two as likely candidates for the most proofs.
Great test for us math/physics geeks!
On question 6, what is the difference between H(b,a,c) and H(x,y,z)?
On question 7, I would have thought that an object at absolute zero would easily absorb energy, whereas an object in thermal equilibrium neither emits nor absorbs energy on balance.

I agree with the others about the theorams. Also yo may want to check into your definition of aphasia. My understanding it that it is a more specfic verbal deficiency
If we assume that a and b are constant integers, Diophantine and Linear are both correct for #11 - it's a Linear Diophantine Equation. Of course if we assume that a and b are real constants, it's Linear but not Diophantine.
I would like a reference for the number of proofs of various theorems. I will change it as well, since one can trivially generate a different, equally correct, proof by adding a tautology.
To other posters: aphasia is a general term for linguistic impairment, but it is often qualified to indicate the nature of the problem, ie, Wernicke's Aphasia, Brocha's Aphasia...
I found this test to be powerfully aggravating. The answer to question 1 is not "light," but rather "the speed of light." I agree with the above statement as well - it's absurd to say in question 16 that both theorems "probably" have more proofs than each other. Question 14 is constructed from sentence fragments.
That being said, I still enjoyed taking it. If you fix those problems, include the answers at the end, and actually score the thing on OKC, you'll have a great test.
Ok, so I have a few complaints. Being a chemist, I can say that 1) you can never reach absolute zero and 2) any object that is in equilibrium is at an equal energy level with its surroundings and will neither gain nor lose energy. So number 7 is wrong.
second complaint. In math, aren't theorems formulas that cannot be proven mathematically but are generally accepted? Thats the main difference between a theorem and a law.
Your blog keeps getting better and better! Your older articles are not as good as newer ones you have a lot more creativity and originality now keep it up!
