It seems at the moment that we are surrounded by more vivid impressions of things that have, in reality, always been there, but that have previously been obscured by other features of our lives. Such things have been revealed by the changes to our lives that have come about as the result of the “lock-downs” needed to reduce the transmission of Covid-19. The birdsong that seems more dramatic and intense than before the traffic subsided. The colours of the trees as the spring light bounces off and filters through the leaves no longer surrounded by a misty haze of pollution (now suggested through its absence). And of course the smell of the coffee hitting our olfactory senses. <\/p><\/body><\/html>\n\n\n\n<html>\n<head>\n\t<meta charset=\"utf-8\">\n\t<title>Superscript and subscript<\/title>\n\t<style>\n\t\tbody { font: 100% Arial, Helvetica, sans-serif; }\n\t\tp { line-height: 1.5 }\n\t\t.ref {\n\t\t\tposition: relative;\n\t\t\tbottom: 0.5em;\n\t\t\tcolor: black;\n\t\t\tfont-size: 0.8em;\n\t\t}\n\t\t\n\t<\/style>\n<\/head>\n<body>\n<p>Before this period of social distancing and self-isolation, I had been preparing for another in the series of <a rel=\"noreferrer noopener\" href=\"https:\/\/www.beanthinking.org\/?page_id=7249\" target=\"_blank\">Coffee & Science evenings at Amoret coffee<\/a> in Notting Hill. The title of the evening had been “Space Coffee” and we were going to explore the connections between what happened in your coffee cup with features that you can see in the atmospheres of planets such as Saturn and Jupiter. Actually the connections are a lot wider than that and can be seen on the Earth too, but the atmospheres of Jupiter and Saturn have some very <a rel=\"noreferrer noopener\" href=\"https:\/\/solarsystem.nasa.gov\/news\/13037\/a-vexing-hexagon\/\" target=\"_blank\">peculiar structures<\/a> that you may not immediately think could possibly be linked to your coffee cup. One of the key people who worked on the science behind this was <a rel=\"noreferrer noopener\" href=\"https:\/\/www.britannica.com\/biography\/Hermann-von-Helmholtz\" target=\"_blank\">Hermann von Helmholtz<\/a> (known as H<span class=\"ref\">2<\/span> to his friends<span class=\"ref\">a<\/span>). For the Coffee & Science evening, the important work of Helmholtz was on vortices and fluid rotations, but it turns out that he has more links with a coffee cup than that, connections that can even give us some food (drink?) for thought in this time of separation.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"alignleft size-medium\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"225\" height=\"300\" src=\"https:\/\/i0.wp.com\/www.beanthinking.org\/wp-content\/uploads\/2017\/10\/TabTab_plants-e1508842756279-225x300.jpg?resize=225%2C300&ssl=1\" alt=\"which will win, gravity or light\" class=\"wp-image-4968\" srcset=\"https:\/\/i0.wp.com\/www.beanthinking.org\/wp-content\/uploads\/2017\/10\/TabTab_plants-e1508842756279.jpg?resize=225%2C300&ssl=1 225w, https:\/\/i0.wp.com\/www.beanthinking.org\/wp-content\/uploads\/2017\/10\/TabTab_plants-e1508842756279.jpg?w=480&ssl=1 480w\" sizes=\"auto, (max-width: 225px) 100vw, 225px\" \/><figcaption>The world has not really been turned upside down, but certainly the way that we view it could be.

In addition to <a rel=\"noreferrer noopener\" href=\"https:\/\/www.britannica.com\/technology\/ophthalmoscope\" target=\"_blank\">inventing the ophthalmoscope<\/a> (in ~1850), Helmholtz was interested in the way in which we perceive colour and how we manage to see in 3D. Thinking about the way in which we see things like light and colour and developing on the idea that how we perceive our world is, ultimately, received in each of our own minds via our sense organs, Helmholtz compared the sensations of light and colour to symbols of language: ways in which we interpret the world around us. As Michel Meulders writes in his fascinating biography of Helmholtz (told from the view point of a medical doctor rather than a physicist)<span class=\"ref\">b<\/span>, Helmholtz had <\/p><\/body><\/html>\n\n\n\n<p><em>“…stated lyrically that we should thank our senses, which miraculously gave us light and colour as responses to particular vibrations and odour and taste from chemical stimuli.
