## 366 days of gratitude

When I was at language school in Spain one of my teachers decided we’d spend an hour on numbers.

My response was, no me gustan los números en español o inglés- I don’t like numbers in Spanish or English.

That’s why I do my best to avoid doing them if I can.

But if I have to do numbers, I’m grateful for calculators and also grateful that, when I use them I have retained sufficient recollection of the basics of maths to know whether the answer is likely to be right or not.

Yes, numbers can get inside you and cause problems. Just recently I tried to work out the wavelength of reflected heat in the atmosphere, and whether the molecular size of Co2 at 300ppm could hold it back. Have another go today.

Well it can Paul Scott CO₂ is opaque to wavelengths in the infra red range and absorbs them

The sunlight reflected by the earth varies according to the albedo of the surface which is close to 1 at the poles and drops down to much lower figures depending upon the surface – reflected sunlight represents a loss of energy available to the system and is of no account

What counts is the energy emitted as black-body radiation, that is the energy that has been absorbed by the planet and then re emitted which follows the famous black body curve in terms of its wavelength.

This absorbed energy is of course what makes everything work – it is what powers our brains and allows us to ponder such matters in the first place

Opaque is an interesting word for these tiny little molecules.
I get
Width of C02 is 3 Amstrom.
Distance between Co2 is 10,000 Amstrom,
heat wavelength heat also about 10,000 Amstrom

That is now what do these Co2 molecules do with the heat waves.
Send them all back in a never ending repeat return frenzy.
The runaway heat cycle.
What energy does the CO2 particle use in this process.
And even if it does send heat waves back, how would halving the numbers of this terrible little character alter things .

4. Paul Scott says:

If the heat wave is absorbed by CO2 molecule, that heat must do something. That is energy can not be destroyed.

5. Andrei says:

It all depends on how you look at it but simplistically the atoms within the molecule vibrate faster

Thermodynamics is a hard subject and you need to be “good with numbers”

Quantum mechanics is a hard subject as well also requiring facility with “numbers” and a discussion of what happens when a CO₂ encounters a photon in the infrared range or any range for that matter requires knowledge of that

Energy tries to even out (Second Law of Thermodynamics) so energy effectively flows from regions of high energy to those of lower energy and in a closed system eventually everything evens out

As this flow occurs though it can do useful things. Our whole existence is part of this process. Eventually the whole Universe will be at a Temperature of about 3K and nothing will ever happen again

Sounds depressing, photons with their own esoteric proceedings.

Not depressing at all Paul – fascinating

And humanities (that is the subset of humanity that is “good with numbers” limited grasp of these “esoteric proceedings” is what makes the wonders of this modern age possible
