Endless arcs & whorls :)
Subatomic particles become visible as graceful arcs and whorls in bubble chambers
(this image from 1978) and other detectors.

20th century hieroglyphs comes to mind when looking at elegant particle physics bubble chamber output as per the graphic seen above. Quantum is reality and tech like this shows why this notion rings true.
How particle detectors capture matter’s hidden, beautiful reality
At every moment, subatomic particles stream in unfathomable numbers through your body.
Each second, about 100 billion neutrinos from the sun pass through your thumbnail, and you’re bathed in a rain of muons, birthed in Earth’s atmosphere. Even humble bananas emit positrons, the electron’s antimatter counterpart.
A whole universe of particles exists, and we are mostly oblivious, largely because these particles are invisible.
To truly fathom matter at its most fundamental level, people must be able to visualize this hidden world.
That’s where particle detectors come in.
They spot traces of the universe’s most minuscule constituents, making these intangible concepts real. What’s more, particle detectors reveal beauty:
Particles leave behind graceful spirals of bubbles, flashes of light and crisp lines of sparks.
CERN’s UA1 detector was active from 1981 until 1990; its most notable discoveries were the W and Z bosons, together with the UA2 experiment. This image shows a section of the experiment, strung with many fine wires, on display at the CERN museum.
