Actually, it's about a fairly simple physical phenomenon. From your weather experts:
WeatherWorks wrote:The heat index utilizes temperature and dewpoint (or relative humidity) to determine how hot the body perceives the environment. Because the body cools down through the evaporation of sweat, moist air will not allow evaporation as readily as dry air. So, in turn, the body will feel hotter on days with higher dewpoint values.
I see Memphis weather says 92° with 78° dewpoint, which is getting into what they consider the "danger" zone - danger of heatstroke etc. Minneapolis 75° with a 68° dewpoint. Tucson is 108°, but a super dry 36° dewpoint makes it, well - "it's a dry heat." If anything less danger of heat exhaustion than Memphis, though 16° hotter on the thermometer.

It isn't fictitious, it's calculated for your convenience, for warm objects that need to maintain a specific temperature and rely on evaporative surface cooling to do that. You can ignore it and rely on your own experience with temperature and dewpoint, or humidity, but I'm guessing that for every 10 people who try that, there will be 5 who get it wrong would be in trouble if they were out doing something strenuous. It will make more sense if you wait till it's cooler and then give it some thought.
Remember, there is no such thing as the average man in the street, but we have the science to prove what the average man in the street is feeling when it is 94 degrees outside and 80% humidity!!
Shut up and listen, you dumb hayseeds!!
I am committed to the advancement of civil rights, minus the Marxist intimidation and thuggery of BLM.
It is winter here in the land of Oz and I DO NOT LIKE IT!!!!!!!
I've been trying to get all the new parts made so I can put the 186 together but I just can't keep the workshop space warm.
AARRGGHHHHH, another delay! My wood fired heater can not cope with cold and windy days and my old bones hate cold; all rather depressing!
Think I'll chuck another bit of wood in the heater, turn the damper down, and grab a big "shot" of nice port and hibernate for the next 10 hours. When we get a nice day I'll get a report and pics of this project up. A "vintage" 186 4V with an accessible 4th valve, double decked, front mount slide which will eliminate the need for a 5th valve. All on a "bench mark" example which has never been beat to sh!t. Sad thing is, it will be up for sale soon after completion, probably at a price affordable to USA buyers.
The port fuelled hibernation plan worked pretty well. At 4:30 AM it was still fairly warm so I only did what had to be done then crawled back into my bed cave and stayed there until 8. The wood supply is running low so didn't keep the fire going. Tonight it will get colder - well below freezing - so will light it up again.
No mira work done except mental design of parts and jig design for fabricating them.
By the way, Bloke, what will do you when you fun out of repairs to do; go fishing? You really sjould stop teasing that poor cat.

And now this non sequitur. I awoke this morning wondering why Chris Olka had not yet commissioned a work called The Olka Polka. It seems so natural. So I just did a Google search, and find that Olka Polka is a line of ladies clothing.
Maybe they could make a Tube Top in honor of Tube Net.

Yep, that's the one. I knew what I was getting but my circumstances took a couple unanticipated twists which is why it is almost 8 years since I got it. I made up my mind about 6 months ago that come hell or high water, (no chance of the latter in the horrible drought we are in) it was getting rebuilt. I am making a new valve linkage set plus a new 4th valve circuit as they were not included; nor were any braces.
I did a test play on it with it all taped together and was very pleased with it.
It seems Chris's posts about it in for sale were deleted some time back. I'll have to get in touch with him to see what background info/documentation he might still be able to provide. I'm pretty sure it is older than the serial number would indicate.
I sold mine months ago. Not really sad though, as I had installed an electric motor on my bicycle, for a ride that for me is more fun overall. Still essentially the bicycle experience and dressed accordingly, so it's nicer in the summer; quieter, cheaper, etc.
