Is There a Limit to the Range of Human Vision?

There is absolutely no problem in defining the temperature of a quantum system in equilibrium. Human vision is limited to electromagnetic wavelengths of roughly 400 to 700 nanometers.

Are there historical decisions that impact us today that you wish have been taken earlier or not been taken at all?
