Ruzzle/Riddle Thread

What is the largest possible number you can write using only 2 digits - just 2 digits, nothing else?
 
Alright, I spent some time developing this little puzzle today. This is my first time posting in this thread, but I only discovered it last night. The following is an encrypted sentence. Who can decode the sentence, and solve the code?

270-15.72-3.93,225+5.24-15.72-7.86+10.48,0+20.96-3.93+10.48-11.79,60+11.79+11.79,120+14.41-10.48+3.93-14.41-1.31,195+9.17-22.27+17.03,270-15.72-3.93,150_PoO_360-1.31,30+14.41-10.48+15.72,0_PoO_15+10.48.

Okay, another riddle I heard today:
We have two spheres in thermal equilibrium, one standing on a thermally insulating plate, one suspended from a thermally insulating string. Each sphere is now heated by the same amount.
Are the spheres at the same temperature, and if not, which is hotter?

I'm guessing that the salient difference is that one sphere is in compression, while the other is in tension... but I don't know what difference that makes to temperature.

How about...

(For the purposes of this puzzle, I'm claiming that the circle around the nine is a digit, because it looks like a zero :p )

What do you mean by thermal insulating? No heat can pass through it, or does it bounce all heat back perfectly?

How about going to the limit with two circles, oo? :)

No heat is transferred via the plate, including by reflection of radiation.
Pete, you're close but not quite there; what happens to the spheres when they are heated?

Eureka!

Ah!
When heated, the spheres will expand and the suspended sphere's center of gravity will drop a fraction while the supported sphere rises.
Therefore some of the supported sphere's heat energy does work in lifting the sphere, and the supported sphere will be (slightly!!) cooler than the suspended sphere.
 
Inspector Clusoau had parked his car under a tree and was heading toward the criminal's house when a vicious German shepherd dog barked at him. Luckily for Inspector Clusoau he was just beyond the German shepherd dog's reach. Since the criminal wasn't home, Inspector Clusoau decided to leave, but he had a slight problem. The shepherd dog, straining at the end of his chain, was following Inspector Clusoau's every move. With the chain attached to ac tree, the vile dog had access to both car doors. How could Inspector Clusoau get into his car without the furious beast being able to get at him?
 
Enter via the trunk?

Or: Open one door so that the dog enters the car, then close it slightly (the chain will prevent it from closing fully), somehow start the engine, take a hose and attach one end to the exhaust and the other end inside the car, then wait until the lethal fumes kill the dog :D
 
I do not think that a dog of avarage dog IQ would enter an empty car while the juicey behind of the inspecter would be in/close to the dog's teeth reach.

Enter through the trunk, possible, but let's say the car keys are in the car and the trunk is locked... :)

He didn't need to get into his car, he never left it to begin with.

"<i>was heading</I>" is in the text (suppose the dog was sleepeing when the inspector came...)
 
He walks around the tree with the dog following until the it's chain was too short to reach the car, and then simply get in and drive away. Because the dog is following his every move, and the fact that he is a dog, the dog wouldn't think to run back around the tree to give him slack enough to reach the inspector.
