Something that looks like an electromagnetic coil on a motherboard, or like a Warp core (an interpretation which I prefer, of course), but is an entirely "analog", very simple, everyday stationery item: A stainless steel pen clip that consists of a strong clip to which a flexible spiral that holds most thinner pencils or pens is attached (so it would have worked for last week's theme as well, but it hadn't been on my radar then). For completeness, I've added a blue aluminium Rotring ballpen that, at some point in its desk life, "lost" its clip (it came loose at some point so I decided to remove it). Colour light helpers were the usual suspects, and I've processed the image in DXO, Color Efex, and Analog Efex, with final touches in LR, which seems to be my preferred processing workflow at the moment.
HMM, everyone, I'll catch up with you tonight!
Is electromagnetic radiation and we generally refer to that which is visible to us. Light is transmitted in the form of waves whose reflection illuminates surfaces, thus allowing us to see objects and colors around us.
The tiny snail loved Physics lessons! She particularly enjoyed studying the electromagnetic spectrum, and the idea that the different colours of visible light had different wavelengths - although it took a while to come to terms with the fact that blue light had the shortest wavelength and red light had the longest wavelength - but with perseverance she was able to get on top of the subject material.
For Macro Mondays theme 'Wavy Lines'. The coloured wires were arranged and photographed to be within 7cm.
No snails were harmed in the making of this photograph.

Like all kinds of electromagnetic radiation. However, in the case of light, we can see the effect this particular kind of radiation has on materials and surfaces (reflections for example). And "seeing" is the brain's translation of what happens to our retina when light enters. The literal meaning of "photography", an artificial term just 200 years old, is "writing with light". We don't. We can't even see light. Our camera is rather a tool to organise and influence our brains' translations of the impact of light. Photographers are translators, not creators in a strict sense. However, there are good and bad translations. Sony A7iii, Pentacon 3.5/30.

Un temporale lontano. Lampi improvvisi illuminano la notte. Sullo sfondo, un cielo blu scuro, cobalto, punteggiato di stelle lontane. Eppure la luce è la stessa, increspature di energia che si muovono ad una velocità inimmaginabile... e pur provenendo da mondi diversi, il mio occhio le sente, le registra insieme, il cervello le interpreta come luce... e io non posso che restarne affascinato. Profondamente.

Explosion over a city on a planet
Please zoom in to see all!
There are 4 fundamental forces (gravitation force, electromagnetic force, strong nuclear force and weak nuclear force) in our universe. Without them, our universe will not exist. The strong force is the strongest of the fundamental forces. It holds together the protons and neutrons in atoms. The weakest of the 4 basic forces is gravity. Every atom creates its own gravitational field which attracts all other matters in the universe.
In other universe, similar forces could be in effect to create different building blocks from tiny particles. These fundamental tiny-particles are created after big bang. The tiny particles, quarks, build protons and neutrons which make up the nuclei of an atom. In another universe, quarks might not form protons and neutrons. Without them, we will not have atoms.
Another universe might also be an atom based universe like ours. In that case, this one would be not very different from ours. It would have same processes to create things. It could have cities like ours.
Endless space might have some smiler universes (smiler to our universe). Without fundamental forces, there will be noting. Similar fundamental forces would create similar universes.

This detailed image features Abell 3827, a galaxy cluster that offers a wealth of exciting possibilities for study. It was observed by Hubble in order to study dark matter, which is one of the greatest puzzles cosmologists face today. The science team used Hubble’s Advanced Camera for Surveys (ACS) and Wide Field Camera 3 (WFC3) to complete their observations. The two cameras have different specifications and can observe different parts of the electromagnetic spectrum, so using them both allowed the astronomers to collect more complete information. Abell 3827 has also been observed previously by Hubble, because of the interesting gravitational lens at its core.
Looking at this cluster of hundreds of galaxies, it is amazing to recall that until less than 100 years ago, many astronomers believed that the Milky Way was the only galaxy in the Universe. The possibility of other galaxies had been debated previously, but the matter was not truly settled until Edwin Hubble confirmed that the Great Andromeda Nebula was in fact far too distant to be part of the Milky Way. The Great Andromeda Nebula became the Andromeda Galaxy, and astronomers recognised that our Universe was much, much bigger than humanity had imagined. We can only imagine how Edwin Hubble — after whom the Hubble Space Telescope was named — would have felt if he’d seen this spectacular image of Abell 3827.

Electromagnetic coils on an old graphics card.
From the basic electronic components I always found the coil the hardest to understand. In addition to the invisible current you suddenly also have this invisible magnetic force (flux). But it's a beautiful component making it a nice subject for this week's theme.
Thanks for all your comments and faves, they are really appreciated. Happy Macro Monday!
Exchanging Electrons with the Electromagnetic Field.
How does a Plasma Ball work?
Inside the globe, there is a high voltage electrode, which is powered by a Van de Graaff generator. When the electrode is energized, it creates an electric field inside the globe.
The electric field ionizes the gas molecules, stripping electrons from the atoms and creating a plasma. The free electrons accelerate in the electric field and collide with other gas molecules, causing them to emit light. The patterns of light that you see in a plasma ball are created by the movement of the electrons and ions in the plasma.
In this case, the Noble gas in the ball is 95% Neon and 5% Xenon.

A more subtle Hubble Palette channel mix ratio of the spectral wavelengths of light, to highlight the different elements in this interesting Deep Sky Object.
Also see the previous version, which was proceeded to more clearly highlight the elements of Hydrogen and Sulfur at the red end of the Spectrum, and the doubly ionized Oxygen at the blue end of the Electromagnetic Spectrum of Light. Rosette Nebula in Narrowband.
About this image:
A Hydrogen-Alpha + Sulfur-II + Oxygen-III Narrowband image of the Rosette Nebula (also known as NGC 2237 or Caldwell 49).
The Rosette Nebula is a large, spherical H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The open cluster NGC 2244 (Caldwell 50) is closely associated with the nebulosity, as the stars formed from the nebula's matter.
The cluster and nebula are at a distance of 5,000 light-years from Earth and measure roughly 50 light-years in diameter. The radiation from the young stars excite the atoms in the nebula, causing it to emit radiation (producing the emission of the nebula at specific spectral lines that we can image).

Demonstrating electromagnetism is way beyond my ability, so I went for straight magnets. I remembered I had this Magnet set from many years ago, so I went rooting in my upstairs closet and found it. The sticks all have strong magnets on each end, and the balls are steel. I had bought several sets, and my husband, grandson and I had a lot of fun building complicated structures with it. It’s a bit addictive. I’m glad we are limited to 3 pictures per challenge, or I would still be building!

Le phénomène “selfie” a infecté les réseaux sociaux tel un virus et le comportement de ceux qui s'adonnent à ces pratiques narcissiques finit par devenir exaspérant !
L’apparition des perches grotesques n’a fait qu’accentuer le problème !
Cette perpétuelle recherche d'admiration et d'approbation de l'autre vire définitivement au ridicule.!
Dès que l'on se connecte aux groupes de discussion de facebook, c'est l'avalanche d'indécence, de niaiseries voire d'autisme…
Plus aucun doute à ce sujet : l'hyperconnexion rend débile et entraîne une dépendance malsaine chez certains.
La maladie de "selfitis" est d'ailleurs désormais reconnue comme une pathologie psychiatrique par les médecins et la controverse subsiste toujours quant à la dangerosité des ondes électromagnétiques émises par nos smartphones, les antennes-relais et la wi-fi 😗
Alors, avez-vous “les artistes”, une idée pour éviter de contracter ces nouvelles maladies du 21ème siècle et comment informer nos enfants ?

Really chuffed to have gone out to watch the Aurorae with Miss Informed tonight. Until now, the best I'd ever seen was a couple of indistinct glowing blobs in the night sky, but tonight was, for the Northern Lights, what the crystal-clear skies of Australia have been for my viewing of the stars.
Things started off quite tame, perhaps overly so until our eyes adjusted, but soon we had half a sky of sorcerer's colours, transiently draping down in curtains and also occasionaly booming across the sky in bows and waves.
Truly a stunning phenomenon to observe.

The Lagoon Nebula (M8, Messier 8 or NGC 6523), is a giant interstellar cloud in the constellation Sagittarius. M8 is estimated to be between 4000 - 6000 light-years from Earth in the Milky Way Galaxy, and is classified as an emission nebula.
About this image:
Imaged in three key wavelengths of the electromagnetic spectrum of light (Hydrogen-Alpha, Sulfur-II and Oxygen-III), over a few nights (due to poor Astronomical seeing conditions, as a result of a very strong jet stream).
About Emission nebulae:
Emission nebulae are glowing clouds of interstellar gas which have been excited by some nearby energy source, usually a very hot star. The red light seen in this picture is glowing Hydrogen captured in the Hydrogen-Alpha (Hα) Infrared wavelength of light at 656nm. The blue light is from doubly ionized Oxygen ions (O2+) emitting at a wavelength of 500.7nm.

Wikipedia defines the "Electromagnetic Spectrum" as the range of frequencies of electromagnetic radiation and their respective wavelengths and photon energies.
The frequency of these electromagnetic waves ranges from below one hertz to above 10 septillion (10,000,000,000,000,000,000,000,000) hertz... with wavelengths from thousands of kilometres long... down to a fraction of the size of an atomic nucleus.
Although our bodies are constantly being bombarded by the entire electromagnetic spectrum... the average human eye is only able to detect the wavelengths between 380 nanometres and 750 nanometres. This is what is known as the "Visible Spectrum".
The rainbow of radiation that is observable to the human eye only makes up about 0.0035 percent of the entire electromagnetic spectrum. That's not very much at all in the grand scheme of things. I often wonder how much more interesting the world would be if we could see more of the electromagnetic spectrum.
So what has this science lesson got to do with this photo of a Yellowwood tree and a sun-star? Hah hah... absolutely nothing at all. :)
