Some Suggestions and Comment
I greatly appreciate your work on this. I think too many people take electric light for granted, and some even look at it as their mortal enemy - the International Dark Skies Association for instance.
I suggest the removal of the term "light bulb" from any article on lighting. It is fine to equate "light bulb" to "lamp", but the lighting industry exclusively uses the word lamp for the "light bulb". "Light bulb" to any lighting person means the glass enclosure of the lamp.
Secondly, I would suggest change to the 1991 Philips entry to simply call it an "induction lamp" like the entire industry does. I would suggest "1991 Philips introduces the magnetic induction lamp; a variety of fluorescent lamp that lasts 60,000 hours." How this lamp works is worth an article unto itself since it is very interesting. I however will leave that to someone that works for a lamp (not a light bulb) company.
Finally, you can find an elaborate treatise on this subject in David DiLaura's "A History of Light and Lighting" available through the Illuminating Engineering Soci3ety of North America (www.iesna.org). I would suggest the addition of this to a list of further reading. All proceeds from the book go to support the non-profit society. Ericbikeco (talk) 17:43, 8 February 2008 (UTC)

"*770 - Iron horseshoes come into common use
- 1492 - Leonardo da Vinci describes a flying machine"
Iron horseshoes should not belong in this list...you might as well add the wheel/stirrup/etc if you want to add the horseshoe. Furthermore, someone "imagining" a method of transportation doesn't warrant being on this list either. This list is purely for actual pieces of transportations used/invented.

adapted from list originally compiled by Niel Brandt RE: Copyright Permissions on this and other timelines developed by Niel Brandt, the following email exchange took place:
I saw your timeline pages, and thought they would be really valuable for the wikipedia project (http://www.wikipedia.com). Do you have any problem with someone posting them there (and setting up links)? Wikipedia uses GNU Free Document License, so your work may be redistributed by anyone in any format.
To which was responded
this is fine with me. good luck!
Source of timelines is various (they have been reproduced across the web). One is http://www.gsu.edu/other/timeline.html
Somebody needs to check the Cugnot tractor. There's serious doubt it ever actually ran, from what I've read. Trekphiler 21:05, 2 December 2005 (UTC)
Hi, folks! A while back, I copied some text from this article over to 1800-1809. This isn't a field that I have expertise in, so further editing of the work in context from other editors here would be greatly appreciated. Thanks! -- RobLa (talk) 02:01, 1 May 2010 (UTC)
Date for invention of the kamal
This article lists the invention of the kamal as 700, but the Kamal (navigation) article states it originated in the "late 9th century." That article cites a book to which I don't have access, but I have no reason to doubt. Obviously 700 is a long way from late 9th century. Anyone else able to confirm the date?

- It appears 13th century (or before) – Rocket missiles used in China. Rocket powered passenger vehicles did not appear until 1939.--Darrelljon (talk) 17:03, 11 March 2021 (UTC)
Typically timelines seem to be lists (see Timeline of the 19th century). They're only likely to be sorted chronologically. A recent edit made sections of the last few centuries into tables which I don't see the advantage of, and it also combined the early and late periods of both the 19th and 20th centuries into whole centuries. This makes it cumbersome.--Darrelljon (talk) 10:34, 15 March 2021 (UTC)
Automatic train operation
2020s looks more like lists than a timeline
2020s looks more like arbitrarily seperated lists (with years) than a chronological timeline. Some items are not significant technological advances for a timeline e.g. Google Maps adds bike sharing, or even the effects of the covid pandemic Darrelljon (talk) 05:37, 25 February 2023 (UTC)
