If it is warmer on the inside than out, the condensation
Read again what I said ... nothing in your quote above changes what I stated in the least.
Frost has nothing to do with condensation. AAMOF, if the conditions are right for condensation, you won't normally see "frost":

clear day without any evidence of liquid water (it's called sublimation), a very cold object can acquire little ice crystals (frost) when the surrounding air is moist enough. See again "dew-point".
I'm guessing they don't teach basic chemistry in middle school (what we called Jr. High) any longer?
I recall, Mr Becker spent a good deal of time on condensation and vaporization in ninth grade chemistry, and in High School we actually learned to calculate the enthalpy of the reactions ... remember that?
Then again, things have changed since a ninth grade in 1957.
:(
You must be thinking of the type of guard that comes with most low to medium price saws that combines guard and splitter. No, you can't use one like that. But you can make or buy an overarm guard that works quite well. And it's much less of a PITA than the guard/splitter combo.
The overarm guards that you can buy are expensive. But some even come with dust collection.

Thermo was college work in Holland. First year '63-64. I don't remember the equivalent of 9th grade high school anymore, thankfully.
I clearly remember that the "State of Matter" was one unit that took up an entire six week grade period in middle school Chemistry.
Thinking back on it, and in contrast to what "education" encompasses today, I now realize what an excellent education we received in those days. Based on the perspective, it was safe to say the education in this country had sunken to such a low point when my youngest graduated in
2002, that it was relatively unrecognizable as such.I'm pretty well convinced that two factors that were in greater supply in those days are largely responsible for the current decline ... discipline, and the quality of the teachers.
The trend downward started in the early seventies around here, and all it took was one complete 12 year cycle to insure that from that point forward, educational mediocrity is the only guaranteed result for the population as a whole.
I use it 2 ways. On wider stock where the guard isn't in the way I'll use 2 of them on long rips where a push stick wouldn't be appropriate and in lieu of using just my palms on the board. The GR does not slip on the board, even if it's sawdusty, the way my hands do. You're holding the board down and against the fence automatically if you angle the GR's top handle towards the fence as the mfg suggests.
Where the GR really shines is in ripping thin slices against the fence. Think cutting your own 1/4" thick banding to cover the ends of plywood panels so the ply grain doesn't show. In other cases, like ripping a 2.5" board to 2" wide, I feel like I have better control of the board with a GR (or 2) than I would with a push stick and feather board. In both these cases I don't use a guard, just run the tunnel in the GR over the blade. Sounds (and looks) scary, but it's actually quite safe as your hand is well above the blade and shielded by the plastic body of the GR. I'm sure it might be possible to get your hand on the blade when doing this but you'd have to really work at it.
Regards.

I love the things!

In my time, we had at least 3 foreign languages in high school. 15 years later, when my yougest sister in law graduated, she didn't even have English. (She is a very nice person anyway).
Discipline is the parents' responsibility, and the baby boom wore out a lot of teachers, I think.
I think a renaissance of sorts is happening now. And, again, when my daughter graduated from high school 22 or so years ago, at a relatively common high school on Long Island, at least 3 out of 200 were admitted to the ivy league college of their choice. If you get a group of kids and parents together who challenge (and help) the kids, miracles will happen.
But they now graduate (at least those the graduate) have good self esteem

English is my second language, can you please explain more clearly? I really prefer Dutch, but that may be too much to ask ...

I'd suggest a green scotchbrite pad and WD-40. Then a cotton cloth, then pastewax.
IOW, the idea in the education industry today that having "self esteem" is more important in the current scheme of things than being well educated, personally responsible, and achieving goals through hard work and personal effort.
Often manifested by programs that include lowering testing standards for certain groups, and the practice of rewarding everyone a prize, instead of just those who excel because of an inherent talent and/or hard work (like eliminating Valedictorians from high school graduations) ... just a couple examples of the misguided nonsense of the "self esteem" card being played in education today.
THAT example is warm air hitting a cool surface.
everyone graduates. Stupid or not. No dummy left behind, remember?
It amazes me how many Americans still need to go back and take "English As A First Language". I know a LOT of people in your position that read, write, and speak English better than most of us Americans do.
Sorry Leon. He's right.
Yep
I agree on discipline, but I don't recall there being a plethora of good teachers back in the '50s. Maybe one out of 5 of my HS teachers qualified as good, 3 as mediocre, and 1 as horrible. I remember only one really excellent teacher.
I hesitate to mention this because it's not P.C., but the rules now force the teachers to teach the unteachable. Also known as the lowest common denominator. In my day, if you couldn't keep up after as much extra help as the teacher could give, you were eventually ignored and given a failing grade. They can't do that anymore, it hurts the kiddies self esteem.
It's the condensing surface that needs to be at or below the dewpoint temperature to cause condensation irrespective of absolute temperature(s).
That's why moisture condenses on the tea glass surface--it's below the dewpoint in the room at a comfortable or even, perhaps, cool temperature.

Unfortunately, that's an entirely falsely manufactured self esteem which will crumble at the slightest touch of reality in the first year after school. And then they're left with absolutely nothing to look forward to but asking people if they would like fries with that...
Except in Han's f'rinstance, where people band together and allow miracles to happen with the brighter kids. They are our salvation.
-- To use fear as the friend it is, we must retrain and reprogram ourselves... We must persistently and convincingly tell ourselves that the fear is here--with its gift of energy and heightened awareness--so we can do our best and learn the most in the new situation. Peter McWilliams, Life 101
