This was a favourite drawing I did at Sketchfu, I can’t remember if it was a challenge drawing or just something I decided to copy because I liked it so much. I enkoyed trying to show the sunlight penetrating down through the water and catching the Orcas back. Its a bit sketchy but not too bad.
Water changes the colours you see, and the deeper you go, the more towards the blue end of the spectrum the colours become. Reds and yellows fade away as you go deeper, until the blackness in the depths of the water absorbs all light. It is at those depths that you start seeing the dim glows of Angler fish. I actually think it would be fascinating to go down in a submercible and to see some of the otherworldly wonders, but I dont think I ever will. But I can use my imagination…
Well since all my photos are in my October file it does mean I can find ones that I took last year and I’m also putting them together in blocks so that I might be able to delete some of the individual ones.
I think these were taken out at the Dorothy Clive Garden in Staffordshire (?) , England, last year. Either it was a showery day, or partly overcast because some have shadows and some not. But they were all grouped together which is why I think they were taken around the same time. Other than that they are random and mostly on the hotter side of the spectrum. A lot of them are daisy types, but I’m in love with the poppy too.
Chemicals create different colours, sodium used in street lights glows yellow. Chemicals are used in fireworks, like strontium (red?) or copper green, creating different colours, blues, purples, oranges.
The reason sunlight is made up of a spectrum is because the sun is made not only of hydrogen and helium but all the chemicals in the periodic table up to iron (any chemicals beyond that can only be created in Super Novae explosions). All the chemicals in the sun glow in different colours, which is why they show up when the white light from the sun passed through a prism. If you split the spectrum further you can find dark lines, these are markers of which chemicals are present. The older the star the more chemicals. As a star gets older it starts to burn up its hydrogen and helium. New chemicals are created by atoms fusing together. That’s where new chemicals are made. When you think about it, if it wasn’t for stars burning or exploding we couldn’t exist.
Talking about artefacts, here’s one off my bookcase. It’s a Spectrum pursuit vehicle I think, based on the vehicles in the 1960’s TV show, Captain Scarlet and the Mysterons. I was a fan as a child of Gerry Anderson Supermarionation puppet shows. They including : Four feather falls, Supercar, Fireball XL5Captain Scarlet, Thunderbird, Stingray and then with live action included Joe 90 and UFO and Space 1999. There are probably more. I don’t remember seeing all of them, especially the first two. I think I got into science-fiction from watching them.
Are they? I think they are. Seen by my friend during a walk. They were in a garden along the canal. These were such a bright colour she took a photo of them.
Flowers are wonderful thing, such amazing structures, with colours outside of the visible spectrum that attract insects to pollinate them. They sometimes use the ultraviolet end of the spectrum to show insects where their nectar is. The trouble with flowers like these is that there are so many petals that the insects can’t get at the nectar. The human intervention of breeding flowers could have a detrimental effect on insect life. There are plants that are advertised as bee friendly, but sometimes that’s all it is, an advert. Single flowered plants are probably best.
Does anyone remember Spectrum? The agency that fought against the Mysterons who came from Mars and attacked the Earth? Captain Scarlet had been taken over by the Mysterons but he escaped. He ended up with the power not to be killed…
Captain Scarlet was a puppet show in the 1960’s and 70’s produced by Gerry Anderson (who also did Thunderbirds, Fireball XL5, Four Feather Falls, Stingray and also Joe 90, UFO and I think Space 1999.
I have this little Spectrum patrol car that was clearly merchandise from the show. I also have an Eagle space vehicle from Space 1999.
When I think about my vision I am so happy that I can see with the full spectrum of visible light (colour) . I know different animals can only see certain colours, sometimes just black and white and but others like snakes and insects can even see into the infra red and ultra violet.
Then there is colour blindness, where some cells in a person’s eye are not properly developed or can be missing. Then they have colours missing from their vision. For instance red green colour blindness. Apparently males suffer from this more than females. As I say I feel lucky to have good colour vision. X
Sodium nitrate, sulphur and carbon. Mixed together make gun powder. That is the explosive mixture they put into fireworks. The ratios of the different elements determine the burning characteristics. Strontium makes red, sodium yellow, copper green, magnesium bright white, other elements make different colours. Cobalt? Possibly blue. The elements burn at different temperatures. Each element, when heated, excites electrons in its atoms. As they cool down again photons of light are given out (emitted). The colour depends on the energy the photons release. Bear with me it gets complicated! In the same way you can tell what elements are in the sun or other celestial objects by their emission lines. If you look at a spectrum (rainbow of colours), given out by the light of the sun there are gaps, these correspond to gases like Hydrogen and Helium.
I don’t know enough science to explain properly.
Anyway the fireworks have stopped so I might go to bed.
