In fact, there is nothing particularly special about incandescence which sets it apart from other forms of luminescence if we think about it a little deeper. In incandescence, the electrons are still individually only emitting discrete photons of energy at specific single wavelengths, or colors, and they're still restricted to "jumping" in specific quantum transitions of energy. It's just that there is such an enormous multitude of individual energy levels available to an electron in a solid material like iron in a forge, or molten rock in flowing lava, or collagen molecules in your skin, that taken together they appear to continuously fill the entire spectrum. Incandescence is simply the word humans use when an object is hot enough such that the "blackbody" radiation it emits is short enough in wavelength to be detected by the unaided eye. This temperature is called the Draper point, and for humans, it occurs at ~525 °C.
It was my hobby to set in sunlight and enjoy photons shower and try to focus on one and observe it's movement. This phenomenon is more visible in early hours of sun rise, although you can observe it any time in daylight.
Great explanation and I loved the animations. It made the content easy to understand. Thanks for the video. Looking forward to more such content. And to be honest, it is my dream to work at CERN. So, hoping to get there some day.
Great video! How can I find other videos in this education series? Hashtags are of no help and on CERN website there's nothing on this. If I'm not aware of something, then please leave me a comment.
You missed a few points, cold objects emit a color, why is that, meaning in addition to infrared they emit their own color. Also when incandescent why are all wavelengths emitted? Why is the spectra continuous? Should it not be unique to the element?

9:43 the accompanying sound effect is synaesthetically appropriate which is conducive to learning.
This was so crucial to my understanding of the link between light and electrons, many thanks!
Great format CERN, keep it up.
8:34 technically, the electron frequency, since it both a particle and a wave, increases or decreases in response to incident photons.
I can see photons since my childhood with naked eyes.

Well, if you were to say the same things in a physics exam, then they will never let you work at CERN. They will simply fail you. :-)
Amazing! I need more like this
Very didatic and interesting
Very concise! Thank you :)
That was great. Looking forward to more videos from CERN.
Is possible calculate amount of universe light, or at least in a room?
Fantastically explained...

Hi,
In the description you can find the link for the playlist. It has 3 videos only.
You missed a few points, cold objects emit a color, why is that, meaning in addition to infrared they emit their own color.
Also when incandescent why are all wavelengths emitted? Why is the spectra continuous? Should it not be unique to the element?
Hi CERN! I love your work
One million points to you. Thanks
Surely colour is created by the cortex? Not by “sources” outside….idk.
the video was very informative. thank u
Also completely wrong in many aspects. If this was written by a physicist, then he needs to give his degree back. ;-)
Everybody has the gift to see photons.
Blind people be like 👁️👄👁️
How can I use this in quantum computing?
For a long time I always wondered why not photons instead of electrons.
How to create something you can see... Our eyes always see this stuff. Cool.. It's science.
There some audio editing mistake(s) ~5 min mark, levels are off.
Real question, how can we actually define the size of photon?
How to detect non existing pretend particles called Photons. Ok, I got it.
Q: How to create photons you can see?
A: Turn on the light. Or heat a metal.
Simple. 19:15 mins saved.
turn on a lightbulb
CERN? They'll never catch up to speed. Why? Because what they do is smash and crash. Not pass along and through.
Yawn material.
Whoever at CERN was in charge of the audio in this video should be fired.
chill
What a bunch of bullshit. Electrons don't like to be exited... so we can see them. It's really cool.
Booooo
