OK so we agree what the energy of a 10 micron photon is, now that I have sorted out my nottaion. That's a minor point though. What I really wanted was to ask a simple question. Supposing you have a single photon, just one photon all by itself, how do you know the temperature of the source from...

Er OK let's use a less abbreviated notation 6.6*10^(-34) * 3*10^8 * 10^5 = 1.98*10^(-20) comments?

Shall we start with arithmetic 6.6^(-34) * 3^8 * 10^5 = 19.8^(-21) = 1.98^(-20) any comments?
