"twice as cold today" :)

it was shrewd:)

You based on celsius temperature scale,For this scale in -273 degree every substance is solid,so it is accepted the coldest heat.To Kelvin heat measurement cannot be negative value.So to kelvin temperature scale water freeze 273 kelvin.so coldest temperature -273 degree equals 0 kelvin.0 degree equals 273 kelvin.273/2 = 136.5 kelvin= -136.5 degree.:P.Beat you:D

Temperature may be quantifiable but the use of twice is relative. I can assign a happiness code based on how I feel. On another day I may be twice as happy but two thirds as happy as I want to be. Let's say a model gained five pounds (she is from the USA) and she says that she is fat. The next week is is up ten pounds, is she now twice as fat, or still beautiful?
