The worlds first riddle!

11. A giraffe's front legs are longer than its back legs.
True

12. It is colder at the Antarctic than the Arctic.
True Im closer so i should know

13. The Earthworm has no eyes.
True

14. The leopard roars like the lion and tiger.
False it grunts i believe

15. A Bimonthly is a magazine that comes out either twice a month or once in two months.
True *resist the bi innuendo*

"As various pictures/scenes are continuously shown on TV with constantly varying degrees of brightness, the iris is made to constantly relax and contract, thus causing great strain to it."

I don't doubt that muscles are strained (fatigued), but I question whether actual damage is inflicted.

"When viewed from the same distance but in their current positions, how many times brighter would the Sun be than the full Moon?"

This is somewhat ambiguous. Is the viewer halfway between the sun and the moon? Not that it matters - I don't know the answer.

I very much doubt it.



Sun and the Moon

As you know, the Sun shines, the Moon only reflects. So lets start by figuring out what fraction of the Sun's energy the moon receives. The Moon has a radius of say 2000 km, while it is 150 million km from the Sun.

Imagine a spherical surface centred on the Sun but with a radius of 150 million km. The energy the Moon receives is only a tiny fraction of the energy passing through the entire imagined surface. In fact it receives about (2000/150 million)^2 of the Sun's energy, the ratio of the areas. So at best, the Moon is 10^10 times fainter than the Sun.

However real astronomy buffs will know that the Moon only reflects 10% of the energy it receives in visible light, so you only gets full marks if you say the Moon is 10^11 times fainter than the Sun when viewed from the same distance.




Four couples have come to a party given by Leslie and Chris. At the beginning of the evening, there is quite a lot of handshaking as people get acquainted. Of course, Leslie and Chris don't shake hands and no one shakes hands with their companion. Later, Chris asks each person (including Leslie) how many hands they had shaken. As it happens, no two of the answers are the same.

It's easier to cancel out the equal numerators and denominators. All are cancelled out but the one and the ten.

"Imagine a spherical surface centred on the Sun but with a radius of 150 million km. The energy the Moon receives is only a tiny fraction of the energy passing through the entire imagined surface. In fact it receives about (2000/150 million)^2 of the Sun's energy, the ratio of the areas. So at best, the Moon is 10^10 times fainter than the Sun."
I would argue that at least half of the sun's energy (the "back" half of that sphere) doesn't contribute to its brightness as observed from a point in space.

Hi guy's, sorry for my late arrival, totally due to a power surge which blew most of the equipment. Sound system/Monitor/TV/etc. However the good news is, I am now sporting a 20 inch Dell, so I can now see what I am doing.

Before you ask, it was the night of the 12th.

In case I have made a mistake, yes, I admit I have made one or two. I give this alibi before any allegations are made.

Well bless my sole, I do believe you are right.


HANDSHAKES
The same as Chris's. (And the number was...)


The maximum number of hands that could be shaken is eight -- everyone except you and your companion. The minimum is zero. And since everyone had a different answer, all the numbers 0 to eight are represented. For convenience, we'll just refer to the guests by the number of hands they shook.

Eight shook hands with everyone except the person she arrived with. So everyone except the person eight arrived with, has to have answered 1 or more since they shook the hand of Eight. And since eight didn't shake hands with her companion, eight came with zero. Now let's think about seven and one. Seven shakes the hand of everyone except Zero and the person she arrived with. That means everyone except Zero and Seven's partner shook 2 or more hands. So the only person who can be One is Seven's partner. It isn't hard to carry on in this way so as to see that Six and Two are partners as are Five and Three. Leslie and Chris are both Four's. And since Chris didn't have to answer the question, all the answers were different. And so Leslie's answer has to be four.




This answer also came up. I post it for completeness.

I lost my league squash match tonight. I also had a freak accident during the game where two of my fingers got caught in the crack between the floor and the wall when I fell going for the ball. I wound up with a few gashes in the fingers, but fortunately neither broke. I did win the point!

"There may be more than one answer but dispute this one: What one doesn't belong; DINE It's the only one that has the letter "I" "

For the second time you have chosen the right answer for a different reason. Way to go Ralph, great lateral thinking.



Mark:

STUDENTS
146+124-200 = 70

If 73% of the students are psychology majors, we know that 27% are not psychology majors. By the same reasoning, 38% are not business majors, because 62% of the students do major in business. So:
27 + 38 = 65

65% of the students are not majoring in both psychology & business, so 35% are double majors, a total of 70 students.

Yes, this one was tricky. If you add an 'e' to the beginning of the first "word," then skip up 3 letters of the alphabet and add and 'h' to the second "word," then skip up 3 letters for the next one and so on, you will see that each "word" really is a word with the first letter removed. The word that completes the sequence must start with a w, and the only option that makes sense is 'oods,' which would be woods.

I greatly enjoy number sequence problems (not).

Keep this in mind when trying this number series enigma.

Just what I thought, you're far too darn smart, and the others are just not too far enough darn smart.

I forget who said:

Perhaps we should distinguish between the subject of a proof and the proof itself. The subject - the underlying truth or its particular expression - I agree is discovered. But I believe a proof is made or constructed. New techniques might be invented to be used in it, or even new language elements.

Taking that last thought a bit further, I think that mathematics, or any section of it, could be said to be invented: include the mathematical language it is expressed in - definitely an invention. (Note that this does not include the proofs expressed in that language! A language is an invention - a novel or recipe book is not.)…
