Heh. I guess if I’d learned to use teh internets properly, I could have looked that up myself. But thanks for the clarification, IVAN!

From Wikipedia — Kelvin (Usage conventions):

Until the 13th General Conference on Weights and Measures (CGPM) in 1967–1968, the unit kelvin was called a “degree”, the same as with the other temperature scales at the time. It was distinguished from the other scales with either the adjective suffix “Kelvin” (“degree Kelvin”) or with “absolute” (“degree absolute”) and its symbol was °K. The latter (degree absolute), which was the unit’s official name from 1948 until 1954, was rather ambiguous since it could also be interpreted as referring to the Rankine scale. Before the 13th CGPM, the plural form was “degrees absolute”. The 13th CGPM changed the name to simply “kelvin” (symbol K). The omission of “degree” indicates that it is not relative to an arbitrary reference point like the Celsius and Fahrenheit scales, but rather an absolute unit of measure which can be manipulated algebraically (e.g., multiplied by two to indicate twice the amount of “mean energy” available among elementary degrees of freedom of the system).

Ah, THERE’s the poetry. I knew it.

Generally, the “surface” of the sun is the part called the photosphere, the layer that emits the light that we see. This is the first opaque layer, so we can’t see below it and the ones above it are (obviously) transparent, at least in visible light.

Please answer the question in #12.

Thanx

The very fact that you think highly-trained scientists don’t understand high school physics should give you a tiny clue that maybe your supposition is wrong.

is that a cromulent word?
