the speed of light and the 1/4wave speaker

I have to do all the work round here!

864 ( = 2^5 x 3^3)
1728 ( = 2^6 x 3^3)
2592 ( = 2^5 x 3^4)
3456 ( = 2^7 x 3^3)

7776 (=2^5 x 3^5)
8640 (= 2^6 x 3^3 x5)

13824 (=2^9 x 3^3)
14688 (=2^5 x 3^3 x 17)
155….

Hope that clears it up. 🙂
Nope.. what does it represent, what are those? Do they represent anything not just a number?

13824 years ago we lost in almost all of humanity almost all of the wholly mammoth and all of the sabertooth tiger, giant armadillo, bear, horse, a giant sloth etc..

subsequently you can trace that back all the way to 66 million years ago with the dinosaurs.

You see the ‘ archaeological and earth science fossil record concludes that this happened in the equivalent of June 30.

And in 1908 something happened on June 30 as well.

these are originates from the same place obviously but it gets more complicated than that.

. 66 million years ago so obviously very vague and not specific. However the time of season is…

1908 isnt vague.
Breaking this down talo huge amount of archaeological evidence which includes near perfect dating at some point.. You will see the next or current situation described as ‘global warming’. But then you trace back to see what it really is and what’s really happening.

it’s much more serious than just numbers it’s your own existence once you look or your grandchildren or your children?

in the past who have come across something similar and they were charlatans or snake oil. They didn’t have tech and info to look into things as detailed as we do now. Yeah we still have people who think the earth is flat… So how are they ever gonna be able to digest this? We are screwed.
 
I thought this was a pretty good piece of Mathematical work:

https://en.wikipedia.org/wiki/Riemann_hypothesis

864 ( = 2^5 x 3^3)
1728 ( = 2^6 x 3^3)
2592 ( = 2^5 x 3^4)
3456 ( = 2^7 x 3^3)
4320 ( = 2^5 x 3^3 x5)
5184 (= 2^6 x 3 ^4)
6048 (= 2^5 x 3^3 x7)
6912 (= 2^8 x 3^3)
7776 (=2^5 x 3^5)
8640 (= 2^6 x 3^3 x5)
9504 (= 2^5 x 3^3 x11)
10368 (= 2^7 x 3^4)
11232 (=2^5 x 3^3 x 13)
12096 (= 2^6 x 3^3 x 7)
12960 (= 2^5 x 3^4 x 5)
13824 (=2^9 x 3^3)
14688 (=2^5 x 3^3 x 17)
155….

My advice is to keep expanding the Series.

I am interested if anything happens with a factor of 163:

Let's not waste time on Random Events:

I have decided to look at this another way!

864 ( = 2^5 x 3^3)
1728 ( = 2^6 x 3^3) = 864 x 2/1
2592 ( = 2^5 x 3^4) = 864 x 2/1 x 3/2
3456 ( = 2^7 x 3^3) = 864 x 2/1 x 3/2 x 4/3
4320 ( = 2^5 x 3^3 x5) = 864 x 2/1 x 3/2 x 4/3 x 5/4....
5184 (= 2^6 x 3 ^4)
6048 (= 2^5 x 3^3 x7)
6912 (= 2^8 x 3^3)
7776 (=2^5 x 3^5)
8640 (= 2^6 x 3^3 x5)
9504 (= 2^5 x 3^3 x11)
10368 (= 2^7 x 3^4)
11232 (=2^5 x 3^3 x 13)
12096 (= 2^6 x 3^3 x 7)
12960 (= 2^5 x 3^4 x 5)
13824 (=2^9 x 3^3)
14688 (=2^5 x 3^3 x 17)
155….

??

Certainly an interesting problem. I ought to be able to cancel certain terms in the fractional numerators and denominators.

Ah wait. I have got it. It converges on 864n. Where n is a very large number. 🙂

I have a feeling I made that harder than it is. Teach me to use advanced Maths on Elementary problems. 😡

I think I am out of my depth here! 😳

Everybody knows that 3^2 + 4^2 = 5^2

Fewer people know that 3^3 + 4^3 + 5^3 = 6^3

And of course that 2^3 x 6^3 = 1728.

I'll stop there. I know my limits.

But 1728 is (1731.41..) is the speed of light, so look at what you’re doing and see how incredibly important it is actually!!!

You’re using a little’cheat’to navigate through things in higher orders that are the speed of light

0.5236 is as well
(0.5238095338 is 30 degrees)
Once you put this into a subwoofer it shows all of it and more

How many hexagon parts as ‘pi pieces’ fit into a rectangle?

I am not sure the 1731.41 is any sort of speed of light I can usefully employ in loudspeaker design.

https://en.wikipedia.org/wiki/Speed_of_light

Is this Astronomical units per day? And that is a purely local Earth definition.

The speed of sound is equally local. On Mars it is considerably slower.

Even the size and orbits of Planets evolves with time. I certainly wouldn't calculate the bass loading on a 1/4 wave loudspeaker on that. Surely Thiele-Small loudspeaker parameters are quite reliable?

Certainly 1728 is a very interesting number:

https://en.wikipedia.org/wiki/J-invariant

But I generally find that everything about regular loudspeakers screams Pythagoras Triangles in Mechanical and Electrical filter matters. And, of course our old friend Pi (3.14159...) pops up a lot. Mr. Troels Gravesen is a safeish pair of hands on 1/4 wave loading. Why reinvent the wheel?

Hope it helps.
