Pictet demonstrated that the reflection of cold can occur, as did others before him.

And everyone after Pictet showed that it does not. I linked a couple of days ago in a different thread to one such example. Did you not read it? Or did confirmation bias not allow you to?

Here it is again:

One-line summary:

"The thermometer, initially at room temperature, now radiates away more energy than it absorbs, and so suffers a decrease in temperature."

Here's another quote for you: "The first principle is that you must not fool yourself - and you are the easiest person to fool." Richard P. Feynman.

Stephen.

It's the one I linked to earlier today, with two other explanations, post Pictet. This nutbar simply does not understand those explanations, or doesn't want to and still clings to Pictet even when shown it was a challenging and interesting experiment, only of its time and is fully understood now.

Alastair really has made an utter fool of himself and shown himself completely unwilling to learn.
