Discussion Overview

The discussion revolves around creating a complex mathematical representation of a birthdate for a tattoo design. Participants explore various creative ideas and mathematical constructs to encode the date in a non-obvious way, focusing on the use of equations and geometric representations.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant suggests using a complicated equation with mathematical symbols to represent their birthdate, 750512.
  • Another recalls a previous discussion where a participant diagrammed the positions of planets at their birth, offering to create a similar graphic for the current participant.
  • A question is raised about the exact time of day related to the birthdate.
  • Clarification is sought regarding the birthdate, confirming it is May 12, 1975.
  • A participant proposes a geometric representation involving regular polygons to derive the numbers 75 and 12, although they express some dissatisfaction with its simplicity.
  • Complex mathematical equations are presented as potential representations of the birthdate, with a note that verification of these equations is needed.
  • One participant encounters technical issues accessing shared graphics related to the discussion.

Areas of Agreement / Disagreement

Participants express various creative ideas and approaches, but there is no consensus on a single solution or method for representing the birthdate. Multiple competing views and suggestions remain throughout the discussion.

Contextual Notes

Some mathematical expressions and graphical representations are proposed but may depend on specific interpretations or additional context that is not fully resolved in the discussion.

Ok, I know this is not too much of a teaser but maybe you guys could come up with something cool and original. I'm getting a tattoo and part of it has my birthdate in it. Except I don't want it to be obvious...I want some type of complicated equation with lots of mathmatical symbols etc so if someone actually worked it out the solution would be my birthdate in international time format 75-05-12 or just 750512 as the answer. Any other suggestions are welcome. The winner will have the satisfaction of knowing their art is permanently on my body:biggrin:
 
Mathematics news on Phys.org
Some one else asked about this a few months back. Their idea was to diagram the positions of the planets at the moment of their birth. I drew a graphic that represented it. I'll see if I can find it.

If that interests you, I could probably whip up the graphic using your birthdate.

Ah yes - https://www.physicsforums.com/showpost.php?p=703716&postcount=8".

What time of day?
 
BTW, that's May 12 right? not Dec 5?
 
Yeah, May 12 1975.
 
Here it is.

not as simple as i'd like, but here's one with regular polygons -
a triangle and 5 pentagons inscribed in a dodecagon...
the 75 comes from 5 (only 1 shown here) x 5 sided figure x 3 (triangle)
5 from the pentagon
12 from the dodecagon. Best I got right now:blushing:
It'd look something like this, but with an actual 12 sided polygon (this one is 15 sided)

[tex]750512=\frac{\int_0^{\infty}{t^{10}e^{-t}dt}}{\pi(11)}+10^4\left(\sum_{k=1}^{4}{\frac{6k}{5^k}}+\frac{383}{625}\right)[/tex]

...I believe. Someone ought to check that.

EDIT: Or also this...

[tex]750512=\frac{\int_0^{\infty}{t^{10}e^{-t}dt}}{\pi(11)}+\frac{\pi^2\int_0^1{\left(\ln{\frac{1}{t}}\right)^8dt}}{12\zeta(2)}+2^4*7*41[/tex]

That's great guys! For some reason it won't let me see the gifs though...it says I don't have permission to access those pages.

You will have to log out, view the gifs, then log back in, it is a bug here at pf.
