Fwiw: heat is a measurable energy that results in the feeling of warmth whereas cold is "absence" (in part) of that energy.

But its also measurable in its own right surely? We can see its affects for example. Its not a void. But then I did opt for literature over science...

The instruments we use to measure temperature actually measure the presence of heat in some form or another [ex. liquid thermometers use a fluid which increases in volume when heat (or energy) is present rather than when "cold" is present]. In the grand scheme of things this probably doesn't matter much haha, interesting none the less.

-_- I recognise when I am out of my depth. But yeah, it's prob not that big a deal lol. XD
