Map To Multiplication
Well not Tesla's work but still interesting - see Sam Collett 's comment & link bellow.
The diagram is intuitive and easy to use. It allows learners and students everywhere to see how numbers work together in a spiral with 12 positions.

I can imagine this as an animation

ReplyDeleteOh that's too bad but good to know Sam Collett .
ReplyDeleteThanks for the update.
Leaves me hungry for a taste of the up-to-it unanswered questions, as their claimed existence prevents asking "What's it good for?" -- which is imo certainly a legitimate question (all the more so given the concluding "Inventor") - and a question that further fuels the more basic question, what is it exactly in its presented intention?
ReplyDeleteAn obvious element is that this simple finite map certainly can't capture the infinity of intricacies of the multiplicative behavior of integers in general; but it doesn't appear to claim to, either.
Looks like a spirograph to me...however I do like the odd-primitive form of the multiplication table.
ReplyDeleteSpirograph changed my life. At 14 I was being taught trigonometry and there was an underused initial HP programmable desktop machine sitting in a lost room with a plotter, so that I applied the trigonometry by plotting spirograph figures, and incidentally started to program.
ReplyDeleteWell, to be totally honest, spirograph was the second programming project, the first had been to list primes:)
A thing, though, is that spirograph can also be served with complex numbers arithmetics in such a way that makes trigonometry superfluous....
(one of my pet "projects" is that of co-populating the earth with synthetic E.T. implemented as humans except for a math education that makes them familiar with what we understand as features of complex numbers and functions, before making then familiar with what we know as features of real numbers and functions. This is a concept I have very lazily been brewing for like 15 years, but thanks to you, Corina Marinescu, it just occurred to me that spirograph could serve as inventive/narrative bias for the part about introducing my ET to real numbers, teaching them trigonometry in reverse, as the bridge to get to real numbers from their otherworldly starting point. I don't know if it really works out, but it's sure fun to contemplate, especially given the most daring complex-numbers-involving pun John Baez ever invented under my stimulation, about sin and cosin).
In the meantime, Alexander Kruel just forwarded the following challenge that to me looks exactly like the kind of things that should be within the powers of Tesla's above Map of to Multiplication.

Wow! This is the nicest infographics I have seen in a very long time!
ReplyDeleteThis is a really nice study in modulo, as the amount of axis can easily be changed from anything from 2 to 100s.
