This film is excellent work. Everything, the camera work, the sound, the choice of music to help tell the story. Invasion, unease, confusion, hypersensitivity, the internalising of stress, sensory overwhelm, loneliness ... literally made tangible in seven-and-a-half minutes. Watched it three times and with earbuds too, and i felt like having lost track of time while watching it. Thought it was like three minutes short but it's actually a five minute walk.

There may be several answers to this. This is my somewhat simplified take.
One is, it's a (series of) physical action (heating, gasification, pyrolysis -- break-up of molecules of the fuel) and chemical reactions (oxidation). Oxidation means in general (in a commonly accepted model) that an atom shares away its outer electrons, which makes it acquire a lower energetic state. Oxygen is one element that is eager to attract such electrons for the same reason.
Whenever such a reaction happens, the superflous energy is released as a quant of electromagnetic radiation (a wave/particle) which we call a photon (it's therefore called an exothermic reaction). Photons can appear to us as visible light (that is wavelenghts in the visible spectrum). The wavelength of a photon inverse-correlates with the energy of the photon (blue > red).
Getting the reaction going however, requires the molecules of the fuel to get excited with energy in the first place, which is the required activation energy. This can be done by heating the atoms of the fuel. And as the oxidation also emits heat energy (far infrared), and in fact more than what is required for the whole phsyical-chemical process to happen, it can sustain itself (given the right conditions, see the second answer). This self-sustaining gassification, pyrolysis and oxidation we call a flame.
Flame colours are composed of the glow of gases at different temperatures ("red" is colder than "white") and the colour corresponding to the wavelength of the photons emitted in the oxidation reaction (simplified). In a typical candle flame, we see mainly hydrogen burning at the lower end (where the flame is blue but the gas is still reatively cold). Carbon takes a bit more activation energy (burns less easily), so it will start to oxidise farther up the flame where the gas is hotter. Carbon will make an orange flame at these temperatures. Other elements burn in all kinds of colours. A burning copper wire will make a flame glow green. Print colours on paper can contain metals which burn in different colours.
The other answer is how I explain how to make a "smokeless" campfire.
A fire needs three things: fuel (something to burn, wood), oxigen (air), and heat. Smoke is just the gases coming out of the wood condensating because they are either not hot enough for activation of the final combustion, or there is too little air getting into the hot zone of the fuel. Anything that is smoke could be a flame when the smoking part is put into a hotter place. Black smoke usually means that there is too little heat for the carbon to get fully oxidised. Cold fuel and having to evaporate water in the wood generally takes away heat from the flames.
TL;DR: A flame is a self-sustaining combustion process in a mixture of gases that needs to be hot and be steadily fed with fuel and oxygen. The gas is so hot that it glows.
I guess it means the DuckDuckGo Browser?

I'm somewhat reluctant to post this wisdom here, though ...
edit: deleted this comment, as this actually deserves a more in-depth and dedicated post in a more suitable place.
Had a look in the modlog... the mod deleted all comments and locked the thread. Looks really a bit strange. I could understand it as not wanting to attract discussions that could get dirty, at all. Critique ageinst the state of israel is often misinterpreted as antisemitism, and discussions around these topics tend to attract antisemites.
Did you ask why a ban was seen necessary?
Can anyone give an actual reason for downvoting this?

There are a few ways. People have set up special websites to index servers and communities:
Lemmy Explorer filters through names and descriptions: https://lemmyverse.net/communities
and there's also still Lemmy Community Browser which is a little older: https://browse.feddit.de/
Community promotion and discovery, there's a lot:
community promo https://lemmy.ca/c/communitypromo
find a community [email protected]
wow this Lemmy exists! https://lemmy.ca/c/wowthislemmyexists
a few more search sites turn up with this filter in Lemmy Explorer: https://lemmyverse.net/communities?query=find+communities
Generally, your home server will know a commuity's existance only after someone has searched for it. I don't know if this has already been fixed, but the advice has been to enter the whole URL of a community into the search bar in order to get it known to your server instance. And once you follow the link in the search result it should start to syncronise, which may take some seconds in the beginning.

afaik Lemmy does not have a tag recognition yet.

And thanks to all who enlightened me about that blue and green and bubble issue. Hmm. my Telegram indeed is set to a greenish-bubbly theme but that's a coincidence.
