Thermal Camera Germanium real heat radiation experiment.
My morning experiment. This is what I do these days, teach (sometimes before class I play these 'toys' with my students), research and write ... and exercise in between.
Germanium is interesting to me because, as a solid, it shares a property that most air does: it is transparent to thermal (infrared) radiation.
Just as an afterthought, the tape can leak infrared radiation, so it is not a perfect (blackbody) absorber of infrared radiation, but is very close.
I am interested in the detector. I think it is the most important detector humans have ever developed (outside the compass). In fact, it helped us understand magnetism and its connection to light. It is the thermopile and its kin (in this demonstration), the bolometer (the thermal camera). But it is old, 19th-century, as is, as a result of the detector, our common knowledge of heat radiation. This instrument is central to greenhouse theory (it defines the greenhouse gases) and quantum mechanics. It is the detector behind the blackbody radiation curve, the Earth's and the Sun's emission curve, and the quantum revolution. But we are not taking on board the 20th-century quantum knowledge, the topic of my book.
But I have found problems with it that no one seems to be addressing. I think its use is limited, problematic and has led to major inconsistencies, including the current Hubble Tension - the age and expansion behaviour disagreement of the universe, the age of the universe through the 'cosmic microwave background radiation (CMBR), also detected by the bolometer, and the main topic of my book, the thermal radiation properties of gases ( the atmosphere).
Anyway, I'm procrastinating, again: get back to writing, Blair!
