Is this the infamous 'Page 38' you are referring to?

So the error is in the pictures themselves?
The picture on the bottom is upside-down.

Okay, team, next brain teaser/IQ test.
Old English Riddle
As I was going to St. Ives
I met a man with seven wives.
Each wife had seven sacks,
Each sack had seven cats,
Each cat had seven kits.
Kits, cats, sacks, wives,
How many were going to St. Ives?
Here's one for you, @DeerSlayer
There is a house with three upstairs bedrooms. Each has a ceiling fixture with a 100W bulb. The wall switches for these three lights are located in the basement. But none of the three are marked.
Your job is to determine which switch goes to which light. You can flip the switches however you like. But you only have one chance to go upstairs to check the status of the lights. How do you correctly match each switch with each light?
Neither kits, cats, sacks, nor wives were going to St. Ives. Only one person - the narrator - was definitely going to St. Ives.
You are correct but you are wrong.
The riddle does not ask if the riddler was going to St. Ives.
It asks: "Kits, cats, sacks, wives, How many (of those!) were going to St. Ives?"
I was cruising from Ft. Lauderdale to Los Angeles in 2013 when I pondered this lovely riddle and posed it to my poker buddies. They all agreed with my analysis.
The reflexive "how many" refers to the precedent subject.
Going through Panama, I won a big pot at six card hi/low Monte with a club wheel, ace through five, both ways.
Declare before showing. One chip in your hand for low, two in your hand for high, three for both ways. You have to win both ways or you lose.
It's correct that the riddle didn't ask about the narrator, only about the Kits, cats, sacks, wives; I answered that in the first clause of my answer, and then threw in the second clause as commentary, not additional answer.
Neither kits, cats, sacks, nor wives were going to St. Ives. Only one person - the narrator - was definitely going to St. Ives.We all learned that answer to the riddle when Zeus kept John McClane from giving the wrong answer in Die Hard with a Vengeance :silly:

The Overcrowded Prison
A prison was overcrowded, and the warden decided to release a prisoner by giving a test.
He had three prisoners brought to his office and explained his proposition.
"The guard behind you has a duffel bag with 5 hats in it. Three are black and two are red.
He will place one hat on each of you from behind you. If you can tell me the color of your hat, you will be released to go home. But you must agree not to guess and if you guess wrong, you understand you will be shot immediately. Agreed?"
[No lose proposition. All agree. Hats are placed on the three.]
First prisoner looks at other two: "I don't know."
Second prisoner looks at other two: "I don't know."
Third prisoner is blind: "I know."
Does he or doesn't he? Explain or you will be shot.
Science IQ Test Number Four
Will a container of pure, distilled water freeze into solid ice at exactly zero degrees Celsius and standard pressure (760 Torr)?
No. It will remain liquid water at 0°C and 1 atm.

Why shouldn't you wear sunglasses while playing tennis, or paddleball?
So if you drop acid before playing tennis, your depth perception won't be as good?

P.S. This board is on a weird time zone I tell you. It's like Greenwich Mean Time.
The forum time zone was recently updated to match that on our new server. For almost everyone, this causes times in articles and replies to display wrong. There is an easy fix, which is to update your profile to tell the forum software what time zone your in. To do this, Go here:

Click on "(auto detect)" next to the Time Offset field.
Scroll down and click the "Change Profile" button.
How do you make the transition from being so smart to the opposite in just days?
Andy, Bill, Chuck, and Dwight hold the professions of aviator, builder, cashier, and doctor, but not necessarily in that order. Only the cashier tells the truth. The other three professions always lie.
Here are three statements. Use these to determine each person's profession:
Andy: Bill is the cashier
Bill: Chuck is not the doctor
Chuck: Andy is the builder
Andy is the aviator
Bill is the builder
Chuck is the doctor
Dwight is the cashier
Science IQ Test #6
How much ice at 0 degrees Celsius will be required to cool one pound of gold at 100 degrees Celsius, just melting all of the ice so that both are at 0 degrees?
No calculations, please. Guess.
(It is a wild and crezzy answer from a wild and crezzy guy.)
Science IQ Test #6None. Zero. Just stick it in a box and set it out on the step for a while. (current outdoor ambient temp is 12 above)

I don't think he's after the practical answer...
Any energy added to any volume of exactly 0 C water will raise the temperature above 0 C and melt it. Using an infinite amount of water ice at 0 C will melt it but will be 1/infinity close to 0 C.
That's the theory I'm going with...
The poster is using for heat of fusion for water. The transition from one gram of ice at 0°C to one gram of water at 0°Creleases80 calories of heat (or 334 joules). So you need to know roughly how much heat is needed to raise the temperature of one gram of gold by 100°C (which is where my guess of 16 cal fell apart).
Water has a heat capacity of 4.18 J/g C degree
Gold has a heat capacity of 0.129 J/g C degree
The heat of fusion of water is 80 times the heat capacity of water, so one gram of gold will cool down 100 degrees C with the loss of 12.9 Joules. Ice will melt absorbing 4.18 J x 80 per gram or 334.4 J without changing temperature!
The ratio of 12.9 to 334.4 or .038576 will apply to any respective quantity of gold cooling 100 C and ice just melting without even changing temperature. So a pound of gold at 100 C requires .038576 pound of ice at 0 to cool it. .038576 of 16 ounces is 0.617 ounces of ice.

Not the change in volume, but in the change of state. Solid ↔ Liquid / Liquid ↔ Gas / Solid ↔ Gas
Water has very unique properties.That ability to absorb tremendous latent heat makes it useful in firefighting, too.
Water has very unique properties.
Water has very unique properties.
Yes it does. It is as if some Intelligent Designer designed it that way. If water contracted when it froze just like almost every other substance, our oceans would be frozen under from the bottom up.

Finance IQ Test
If your forebears had invested the equivalent of $1.00 U.S. in the Bank of Israel
2000 years ago.
It pays 4% annual compound interest rate.
Guess, don't calculate, how much gold that would equate to at the current spot price.
You will not be within several orders of magnitude.
The Bank of Israel was founded on 24 August 1954.
