The amazing discovery of the refrigerator industry
They found that there was a limit to the cold.
The ovens industry has not discovered that there is a limit to heat.

Physicists did not answer this question.
Geometrics provided an interesting response.
There is a limit to the amount of space that a given length can contain.
What is the connection between a refrigerator and geometry?
