And then my friend there is the vernacular. When it’s cold outside, it means your body will not comfortably be able to sustain it’s temperature, so wear a sweater. If someone offers you a cold drink, expect a beverage slightly above the freezing point of water. If you’re pouring your child a bath, and she request that you make it colder, add more water from the tap marked “cold”.
It’s like knowing the difference between fruits and vegetables AND knowing the difference between knowing the difference between culinary fruits and vegetables. No one gives a crap if the string bean is botanically a fruit, it’s a vegetable.
Hence my statement that this is a GEEK joke.
When you work with engineering, we use measurements like enthalapy and entrophy, coefficients of thermal expansion, etc. These deal with various levels of heat.
Cold does not exist, cooling is simply the rate at which heat is dissappated into the universe (hence the statement that the entrophy of the universe is always increasing). You cannot destroy energy, so where does all that heat go?
But, please don’t shoot the messanger - I merely passed the message on to driftdiver, who asked if Cold existed.
