Those microscopic views of LP grove reveal one important point . With an otherwise pristine looking LP, even new ones, it is caused by micro dust in the groves. Micro dust is everywhere and can never be eliminated in a home environment. For one thing, the average human sheds about 1.5 pounds of skin cells a year. That is about 600.000 particles of skin every hour, which works out to be about 1.5 pounds of skin per year, per person Add to that if you have a family and pets. I am fanatical about LP dust removal and my LPs are almost as quiet as a CD.... even mono LPs from the 1950s
+Steves Projects It is surprising to see how little of the needle goes into the groove. It's because we always see representative pictures showing the needle deep in the groove. It's like the earth's atmosphere. We've been lead to believe it's like a thick blanket around the earth but in fact, at the scale of a school globe, it is the thickness of cellophane wrap - so thin as to almost not be there. But showing it that way in little diagrams doesn't work for presenters so we keep seeing the misleading images. Another one is for radio people who have seen a thousand times the diagram of a signal bouncing off the sky. Imagine that with the cellophane model and it really doesn't seem possible. For sure you cannot make that bouncing signal diagram. And I have more because I love things like this where the common sense is just wrong.
@@JimsRadioShop Your description of the relative scale of the neutral atmosphere is accurate, but the layers of the ionosphere that enable skywave propagation are at a much higher altitude, between 100 and 800 km, or 2-12% of the Earth's radius. At these altitudes, line-of-sight distances to the horizon can reach 2,000 km, or 5% of Earth's circumference. In other words, it is absolutely possible to make a comprehensible scale diagram illustrating skywave propagation. I think your point is otherwise interesting and can be applied to, e.g., models of the atom or representations of the solar system.
Thank you SO much for making this amazing video. I actually experienced a very emotional response "seeing" sound. The world and our bodies are amazing entities. The future aliens will love this one. 😉
@4:00 More grooves and they squeezed, so less dynamic range. Interesting video. Man, those records are dusty and greasy. What needle is it? Did you try a MC stylus? If I want images like these, which microscope would you recommend, now thinking inexpensive USB microscopes.

8:26 lmfao just out of nowhere hahahaha

That was really interesting up close and personal with the vinyl
The tracks are so narrow its amazing the stylus can actually stay in the grove reliably when playing

There is only 1 groove on a record.
2 actually, if you consider both sides on most records ! A couple more for the mystery records.
ima defacate myself if somebody says 3
Groovy video man!
really enjoyed the video Jim..
hello - how can we understand if the grooves are clockwise or anticlockwise ?
It is possible under the right lighting to see these grooves with the naked eye and distinguish between them?
Could you please do a video like this where it shows the record spinning on a turntable but magnified that would be cool
Thanks for the cool video. Do you remember what was your magnification or FOV?
Dear friend! What was the optical zoom?
Do you think the sound from the groove of the 78 can be taken from those microscope pictures?

How many times is it enlarged?
Could you explain which model of the microscope you are using for?
I think this is a video 4k would actually be really useful for
niiiiiice!!!!!!
That was interesting..maybe next take a look at a cd....Buzz
cd pits are very tiny
Haha, meditative science.
what point are you trying to make,the wear ,or what?
