Retrospection 9

*About Teeth, Human & Animal, Dentistry & Dental Health, Gems & Colour.* A friend of mine once said that there are three things all people are interested in, even if they don't always want to admit it: sex, money and teeth! When he said that, I questioned whether teeth really were in parity with sex and money. Later, I have realised that they are. Most people have problems with their teeth, sooner or later, and such problems come with much pain, cosmetic trouble, and huge economic strain. Nobody can ignore the subject of teeth; everyone, absolutely everyone, would benefit from understanding teeth better, what it is and how to take good care of them. I have written a series about teeth, and it has its own label in my Index. There you can presently find 6 articles: https://read.cash/@Mictorrani/index-over-my-articles-at-read-cash-5f7c1e34#teeth Dentistry - A Modern Luxury?

The sixth article, Tusks & Ivory, can also be found under the label Gems, which I recently added. That topic presently includes: https://read.cash/@Mictorrani/tusks-ivory-dfe625f7 https://read.cash/@Mictorrani/index-over-my-articles-at-read-cash-5f7c1e34#gems Once the Most Precious Gem on Earth https://read.cash/@Mictorrani/once-the-most-precious-gem-on-earth-71626df2 Tusks & Ivory https://read.cash/@Mictorrani/tusks-ivory-dfe625f7 Genuine Ultramarine, Once One of the Most Costly Pigments in the World https://read.cash/@Mictorrani/genuine-ultramarine-once-one-of-the-most-costly-pigments-in-the-world-8ac3c605 Amber, Organic Gem with a Long History & Many Properties, Part I https://read.cash/@Mictorrani/amber-organic-gem-with-a-long-history-many-properties-part-i-9ea705bb Amber, Organic Gem with a Long History & Many Properties, Part II https://read.cash/@Mictorrani/amber-organic-gem-with-a-long-history-many-properties-part-ii-fa6314f8 It should be noted that most people think of gems as “gemstones”, mineral gems, but there are organic gems as well: most notably pearls, amber and ivory. “Ultramarine”, however, is the mineral Lapis Lazuli, a gemstone. I have been asked to continue this series with more about mineral gems. It may or may not happen, nothing has been decided about that yet. People who follow my writings here have noticed that I have just published several articles about colour, where I try to explain what colour is, how and why we see different colours, and the purpose and effect of colours; and colour is important. In “Colours III: Function, Purpose, & Effect of Colour” I wrote: https://read.cash/@Mictorrani/colours-iii-function-purpose-effect-of-colour-de0b4e94 “Sight is the dominant human sense. Of the perceptional (from our five ordinary senses of perception) information our brain receives, 80-90% is related to sight, and of that more than 80% is related to colour.“ Colours I : The Nature of Colour 1 https://read.cash/@Mictorrani/colours-i-the-nature-of-colour-1-0e75a695 Colours II : The Nature of Colour 2 https://read.cash/@Mictorrani/colours-ii-the-nature-of-colour-2-b4e4b528 Colours III: Function, Purpose, & Effect of Colour https://read.cash/@Mictorrani/colours-iii-function-purpose-effect-of-colour-de0b4e94 This ***chromocentric*** perspective will be reflected (no pun intended) in a few soon forthcoming articles as well. Indeed, I recently created “Colour” as a new separate topic in my index . There you'll also find ***chromocentric*** articles from the past, most of which you can or could find under the label “Eyes, Light, Vision, Blindness”, which I discussed in Retrospection 7 . Those that were not there, are, beside the new articles mentioned above, some articles related to colour and art: https://read.cash/@Mictorrani/index-over-my-articles-at-read-cash-5f7c1e34#colour https://read.cash/@Mictorrani/index-over-my-articles-at-read-cash-5f7c1e34#eyes-light-vision-blindness https://read.cash/@Mictorrani/retrospection-7-ec5d208c Aka-e – Japanese Colour Magic and Prussian Blue & Aizuri-e - Blue Pictures, both related to Japanese art – and Sepia, Grisaille & Verdaille: Monochrome Art... and how about Japan? , which has as well a Western as a Japanese perspective. https://read.cash/@Mictorrani/aka-e-japanese-colour-magic-f89cf7e4 https://read.cash/@Mictorrani/prussian-blue-aizuri-e-blue-pictures-dc563ddd https://read.cash/@Mictorrani/sepia-grisaille-verdaille-monochrome-art-and-how-about-japan-da2aed40 For those who wonder, *“****chromocentric****”* here means *“colour-centred”*. The word is used in genetics, mainly in the form “chromocenter”. Its exact meaning is technical and would require a long explanation, let's just say that there it has to do with chromosomes. However, I have not found it used in the general meaning as “with a focus on colour”. For this purpose I created it as a combination of “chromos”, which means “colour” in Greek, and “centric”, which needs no further explanation. About creating new words, see Retrospection 3. https://read.cash/@Mictorrani/retrospection-3-d8bc8727 Also for those who wonder... My material about Japan, and my familiarity with Japanese culture and language, have made some readers assume that I am Japanese. I am not, but I have what we can call strong family links to Japan. My series “Retrospection” is primarily created for new readers of mine, as a manual into my production at this platform so far - but it can be read by anyone who wants to explore my articles topic by topic, rather than doing so in chronological order. In addition to that, my retrospections contain new comments and from time to time short personal stories connected to the relevant topic or topics. https://read.cash/@Mictorrani/index-over-my-articles-at-read-cash-5f7c1e34#retrospection Previously published “Retrospections” are: Retrospection 1 (About Japanese Art & Cultural History.) https://read.cash/@Mictorrani/retrospection-1-a78bc572 Retrospection 2 (About Egyptology & about Coffee.) https://read.cash/@Mictorrani/retrospection-2-a54911f7 Retrospection 3 (About Quotes, Sayings and Proverbs; and about creating new words.) https://read.cash/@Mictorrani/retrospection-3-d8bc8727 Retrospection 4 (About dinosaurs, reptiles, dragons and to some extent birds.) https://read.cash/@Mictorrani/retrospection-4-0c1add0e Retrospection 5 (About Privacy, Freedom and Politics.) https://read.cash/@Mictorrani/retrospection-5-aaa611cc Retrospection 6 (Suggested reading.
