How did people travel before aerospace engineers invented passenger airplanes?

What makes you think it’s a comet?

And allow me to add, some people just like the glow of the tubes, the authentically old design of the case, and yes, the smell. I’m one of those.

Yes, that is part of being a good Scientist. Too many fellow Engineers I know take a measurement, do some math, and will maybe truncate a number or two. It is rare that I see accompanying error analysis.

The schematics say “Trim RV2 to obtain VDC/2 on TP1”.

TP1 is connected to circuit ground. The instructions should mention that we need to use the Baron Von Munchausen method for trimming it.

Nope, both of those have experiments.

More to the point, even if you don’t have a repeatable test and you only have data from an event that happened once, you can still do experimentation on the data. By holding off some of the data, you can then build a model and test it against the withheld data to see if it makes correct predictions.

Of course that doesn’t prevent you from coming up with false theories that happen to fit the data, or over-fitting your models – it’s just less likely that your model happens to fit both sets equally well if it’s completely wrong.

It’s probably some interaction of browser settings / script blocking, and whatever WordPress’ comment engine uses to attach comments to their parents.

There could also be a race condition with comment ID numbers? But so far, it looks like it’s happening to some individuals more heavily.

What “blocking” plugins do you use, on which browser? We’d love to figure this out.
