colour coding is brilliant
Thank you for this. It's the first time I really understood Simpson's Paradox, despite having seen it before. The breakthrough was the colour-coded plot in Figure 4. Brilliant way of explaining it.
Would you care to step into a time machine and take the place of my *first* statistics teacher in 1982?
ring terminal on thermocouple (or thermistor)
That's clever! I like the aluminium crimp lug on the end of the thermocouple wire. In this situation (and for the original aquarium heater application) the increased thermal time constant won't matter, and it makes it dead easy to attach. Seems like an effective way of protecting delicate thermocouple junctions. Brilliant!
On second thought, it might be a thermistor glued inside there, not a thermocouple (it's not been crimped). Still a good idea so long as the adhesive is thermally conductive.
Turn these into a book NOW.
I hope you understand that I'm accumulating these articles in a folder. And regularly re-consulting them before I make career decisions. Having worked in both finance and aerospace, let me tell you the principles are surprisingly portable. A few word substitutions ('line' for 'traders' and 'security' for 'compliance' come to mind) and it matches the environment inside a large government/military contractor.
Turn these articles into a book, now, and I'll see to it that a few hundred copies are bought by engineers at my site.
