Lower-case q?
- Lower-case q? Peter Jackson (talk) 10:21, 25 November 2020 (UTC)
- I would be fine with making q lower-case, especially if that is standard Citizendium format. Mark Widmer (talk) 02:07, 2 December 2020 (UTC)
Planned additional sections
This page is a work in progress, and the following benchmark units are planned or proposed.Mark Widmer (talk) 02:07, 2 December 2020 (UTC)
- Acceleration
- Power
- Force
- Pressure
- Electric charge
- Voltage
- Electric field
- Coefficient of thermal expansion
- Money/currency? Really not a physics topic, so arguably doesn't belong here. But could be useful, if not here then maybe in a new page of non-physics benchmarks?
Alphabetize the sections?
It might be useful to sort the sections into alpabetic order, though I am unsure how you would sort a section with multiple names, such as Angular or rotational speed. Pat Palmer (talk) 05:45, 7 December 2020 (UTC)
- Good idea, I have alphabetized the sections. Mark Widmer (talk) 02:45, 8 December 2020 (UTC)
Style/guidelines/scope for article
In creating this article, I had in mind a page that's layperson-friendly, while maintaining accuracy as a useful reference. With that in mind, and trying to keep a consistent style through the article, I've been trying to follow the following guidelines Mark Widmer (talk) 02:57, 27 December 2020 (UTC)
- Give most values as 1 or 2 significant figures, while quantities that are considered definitions might go to 3 sig figs.
- That being said, I'm still mulling over using 3 sig figs for densities of elements.
- For very large or very small numbers, use both
- scientific notion -- for it's compactness and making it easy to compare widely different numbers -- and
- common language like "30 billion" or "30 billionths" -- because it's more likely to be understood by laypeople -- while
- not writing numbers as, e.g. "30,000,000,000" or "0.00000003" -- because I've never been fond of having to count a bunch of zeroes.
- Stay away from obscure quantities that only experts would be familiar with, such as:
- The fine structure constant
- "Planck values", e.g. Planck length, Planck time, Planck mass, etc. (I had some of these initially, but have since deleted them as not being layperson-friendly. Plus, I admittedly do not think they have any real significance other than they happen to be what you get when various fundamental constants are combined.)
- Properties of quarks, neutrinos, and any subatomic particles other than electrons, protons, and neutrons. (Note, Dark matter is mentioned in the Density section.)
- For the "Quick scale" paragraphs, use reference objects that people are either familiar with (The Sun and Earth, a typical person, an FM radio signal, air) or have likely heard about frequently (a hydrogen atom, the speed of light).
