Dear Macchess, I just uploaded a few heliotrope images to commons:Category:Heliotrope. Please take a look and replace those in the article as you find fit. Cheers, Waldir talk 12:25, 11 June 2008 (UTC)
Hi Macchess. I just checked the image, it's excellent! I added a template to see if someone so inclined would do a cleanup in the pattern in the background. Look at the links in that template, or see
this image (
previous version) for an example of what can be done. But nevertheless it already is very good! It was also a nice idea to upload new versions of the other images, cropped to better show the detail of the instrument.
As for
Image:Heliotrope2-2.jpg, I edited it to remove the scratches, as I said. Tell me what you think. -

Not sure why I did that. I must have been trying for something else. I re-rolled it back to the ip's edit. something lame from CBW 08:09, 18 February 2010 (UTC)
The big problem with those articles is that they don't have enough reliable sources. I would help with that, but I really have no idea where to start. -- Boycool ( talk) 22:14, 14 May 2011 (UTC)
My source for hooke's heliograph was from a historical/chronological book called 'British History' by Rodney Castleden. However, I looked through the document of his presentation to the Royal Society and Hooke's device doesn't seem to have operated on the principles of the heliograph, as you pointed out. So, I guess if you think it's wrong then it can be taken out. Thanks. Noodleki ( talk) 12:48, 23 April 2012 (UTC)

Hi. Thank you for your recent edits. An automated process has detected that you've added some links pointing to disambiguation pages. Such links are usually incorrect, since a disambiguation page is merely a list of unrelated topics with similar titles. (Read the FAQ • Join us at the DPL WikiProject.)

I threw that note in because a few months ago I myself got the impression from that very article that the relationship between unit quats and SO(3) was a bijection rather than two-to-one. I appreciate the attention you've paid to the subject. However, I'm uneasy about making a distinction between "rotations" and "rotational transformations." To me rotations are a subset of transformations, so this doesn't quite parse for me. Is there a source somewhere that makes a distinction between these two? 11wx ( talk) 05:37, 13 December 2022 (UTC)
I gave an example of two different rotations (physically distinct processes) that produced the same rotational transformation:
"If 0 ⩽ ⩽ , the rotation about by and the rotation about by both achieve the same final orientation by disjoint paths through intermediate orientations."
Both these rotations result in the same rotational transformation, but are two very different rotations - they are in the opposite sense, and share no orientations other than the common start and end points - if they are achieved as physical rotations that are continuous processes that take finite time, the intermediate orientations each pass through are disjoint sets. What is unclear about that? Would it help if I said "physical rotation" rather than "rotation"? I'll make that change now.
