All, I am taking this off-list since it is so far off topic. What I said seems to have been somewhat misinterpreted.
1. "Threshold of pain" means it starts to hurt, not "I can't stand it any more". 2. The surface temperature of a child's forehead when running a fever of 106 degrees is less than 100 degrees. The 106 is an internal temperature. 3. This is a "rule of thumb", not an absolute. Run the experiment yourself: * Come up with a way to measure the temperature of a hot surface. Maybe an over window could be used, but you need to measure the surface temperature. Using a forehead thermometer will not work since it has bee calibrated to read internal temperature based on the cooler external temperature. * Heat the surface to 99 degrees and see how it feels. * Then try it again at 100 or 101 degrees. Yes, individuals can handle much hotter temperatures. I once saw somebody reach into a hot fish-frier and come out unburned; but he had been working in the frying industry for years and had built up the ability to to that. This "rule of thumb" is based on a "normal average". 73, Fran > On Jul 3, 2021, at 19:52, David Woolley <[email protected]> wrote: > > 100°F is well within the survivable body core temperature range, so it should > never trigger pain receptors. > > In fact, I believe it was defined based on the nominal core body temperature > of a cow. > > Did you mean 100°C? > > -- > David Woolley > > > On 04/07/2021 00:03, Francis Belliveau wrote: >> Another rule of thumb for those who care. >> When you hold a finger on something and it is 10 seconds to pain threshold, >> that location is about 100 degrees F. >> This is not an absolute constant, but I have checked it a few times since I >> was told that, and it seems to be true for me. > > > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:[email protected] > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > Message delivered to [email protected] ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
