Set three balls aside. Divide the remaining 6 balls into 2 groups of 3 and weigh them. If the groups weigh the same, the lightest ball must be in the group you set aside. Otherwise, the lightest ball is in the group that weighed less. Take the group of thee that remains and set aside one ball. Weigh the other two. If the two balls weigh the same, the lightest ball must be the one you set aside. Otherwise, the lightest ball is the one that weighed less.

Find the weight of Tweedledum and Tweedledee?
In this hypothetical problem written by Richard Rusczyk: Tweedledum says, "The sum of your weight and twice mine is 361 pounds." Tweedledee says, "Contrariwise, the sum of your weight and twice mine is 362 pounds." If they are both correct, how much do Tweedledum and Tweedledee weigh together? Tweedledum and Tweedledee weigh 120 and 121 pounds respectively. (NB: Tweedledum and Tweedledee never actually had this converstion, and in the original book their weight remains a mystery...)
Tweedledum says to Tweedledee The sum of your weight and twice mine is 361 pounds Then Tweedledee says to Tweedledum Contrariwise the sum of your weight and twice mine is 362 pounds Find the weight?
To get Tweedledee's side of it, divide 361 by 2 to get 180.5 lbs. Since they are the same exact size and age in proportion to their body size, shape, and age, then they are both 180.5 lbs. To find half of 361 lbs., just divide it by 2. To get Tweedledee's side of it, do the same for that number, and you get 181 lbs. They are arguing with one another as to what their weight is.

How can you tell which of three balls is the lightest or heaviest using a simple balance that consists of two pans?
Tough question to get into one sentence! You can do it in two weighings. Select any two of the balls and place one on each pan. If the scale balances, the third ball is the oddball. A second comparison will determine whether the oddball is lighter or heavier than the other two balls. Simply replace one of the first two balls with the oddball. If the oddball is heavier, its pan will drop; if it's lighter, its pan will rise. But what if the scale fails to balance the first time? (It is twice as likely that the scale will fail to balance when selecting two of the three balls at random for the first comparison!) If the scale fails to balance on the first comparison of two randomly selected balls, then you know that the oddball is on the scale, but you do NOT know which one it is, and you don't know whether it's heavier or lighter than the other two. A second comparison will resolve those issues. Remove the lighter ball from its pan and replace it with the third ball. If the scale remains out of balance, then you know that the heavier ball is the oddball, which is, of course, heavier than the other two. If, however, the scale balances, then the ball you removed is the oddball and is lighter than the other two.

Why Does it make sense to say that one body is twice as hot as another?
because we have absolute temperature scales (Kelvin and Rankin). Something at 20'K is twice as hot as something at 10'K.
