I find that the zeppelin part doesn't make much sense as modern zeppelins are filled with helium rather than hydrogen... even "classic" zeppelins were filled with helium if available. The main resaon for the Hindeburg not being filled with helium but hydrogen was a helium embargo by the US. https://en.wikipedia.org/wiki/LZ_129_Hindenburg#Use_of_hydrogen_instead_of_helium [[User:Elektrizikekswerk|Elektrizikekswerk]] ([[User talk:Elektrizikekswerk|talk]]) 09:04, 28 January 2021 (UTC)

Just for reference: the maths to scale down the Niagara Falls flow an convert from cubic feet to cubic centimeters:

> 1e5*(.3048)^3*1000^2/(1e3)^3
[1] 2.831685
> 1e5*(.3048)^3*1000^2/(1e3)^3/2
[1] 1.415842

American editors may want to adapt the formulas to add the numbers in cubic inches.--Pere prlpz (talk) 18:29, 27 January 2021 (UTC)

do we have a category for these small scale world comics if not we might want to discuss that. 162.158.75.246 18:51, 27 January 2021 (UTC)

Based on the original Star Trek canon, I believe it more than reasonable to say that all of the Enterprises would be able to operate at least partially submerged, but I would be very worried about a scale aircraft carrier breaking in two if lifted. 162.158.62.115 20:56, 27 January 2021 (UTC)

Tensile/shear strength works on cross-section, so would be proportional to the square of the scale, not the cube. A scaled-down Golden Gate Bridge would only support a millionth of the full load, not a billionth, so the proportional load is only 0.3 of a person. (And it basically wouldn't have to support itself, which, as it turns out, takes care of most of the remaining part.) --162.158.183.117 22:07, 27 January 2021 (UTC)

Neutrino Detector/Observatory seem to be 2 different things? one under an icesheet, one in tunnels? Some light should be shed on what they are, where they are, wether the ice sheet is to scale, etc. Also why the implication of the neutrino detector being functional ("The fact that people are not supposed to create false positives implies that the neutrino detector is functional.") - also: The no hot stuff on the ice could be just about not melting the ice and therefore destroying the model, instead of messing with the detectors... --Lupo (talk) 06:25, 28 January 2021 (UTC)

Only particles that travel faster than the speed of light (in ice) will emmit Cherenkov light, so the part about the "hot objects" is incorrect.

Order of comics

I wonder why he posted this one after the 1/10,000 and 1/100,000 comics instead of publishing them in order. My thought is maybe he worked on them simultaneously but this one wasn't ready, or maybe he made this one because he felt the response to the previous two was positive. 172.69.68.11 23:50, 27 January 2021 (UTC)

Small planes

I was fascinated by the east/west layers shown under "Watch for small planes". I assume this is in reference to actual US FAA and/or global practices? And of course the next question that occurs to me is what about planes flying due north or due south? Can anyone fill in some notes on this? 108.162.245.18 01:12, 28 January 2021 (UTC)

Global. Well, not entirely universal, but common for lot of countries. See Semicircular Flight Level rule. Apparently, New Zealand, Italy and Portugal prefer to divide by North/South but most countries use West/East. -- Hkmaly (talk) 01:34, 28 January 2021 (UTC)
Any aircraft with a heading from 0° to 179° is considered to be flying "east", and one with a heading anywhere from 180° to 359° is considered to be flying west. (Headings get rounded to nearest degree, so nobody flies at 359.5°.) Traffic headed east flies at odd flight levels (31,000 ft, 33,000 ft, etc.) while traffic heading west flies at even flight levels (30,000 ft, 32,000 ft, etc.) -- 172.68.174.132 03:38, 28 January 2021 (UTC)
