RFV-sense "The sum total of all the complex processes of a single lightning event, including both what is invisible and what is visible or discernible to the human eye." That appears to be saying that not only the bright, well, flash of lightning, but also "the invisible processes" of it can be called a "flash". - -sche (discuss) 09:03, 23 March 2013 (UTC)
- I think the wording is overly verbose, but I guess it's saying the non-visible parts such as the electricity are also part of a flash of lightning. Mglovesfun (talk) 10:53, 23 March 2013 (UTC)
- You are both correct. I wish "lightning" was as simple as people often make it out to be, but it's not, and it is often de facto "defined" as a verb describing the visible "flash" like a, ummmm "flashbulb" or "camera flash". :\ Here is at least one source. Uman/Rakov's "All About Lightning", the definitive guide on lightning will clearly specify as well. Let me know if you need more. Ironically, the scientific community adopted other similar verbs of what we see in lightning to name the processes [noun/proper noun] associated with it, i.e., "Strike", "Stroke", "Attachment", to name a few.... It has not made scientific/technical discussions about lightning easy. Cheers Borealdreams (talk) 14:29, 25 March 2013 (UTC)

Flash sale[edit]
Isn't the meaning of flash as in flash sale missing? Or am I missing something? --The cool numel (talk) 20:14, 4 October 2021 (UTC)
"To communicate quickly."[edit]
I have always been confused by the use of "flash" when we say "flash message" or "flash flash flash" or similar. How does this originate? What ancient piece of 20th century technology was being "flashed" when sending messages? Or does this mean "speedily delivered"? --Geographyinitiative (talk) 12:11, 12 September 2022 (UTC)
