nerdyversary 0.1.1

Package for computing nerdy anniversaries

Nerdyversary

Small project about finding "nerdy anniversaries". An obvious example would be that after 3.1415... years one could celebrate the $\pi$-th anniversary. The code in this repo finds nice combinations of numbers like $\pi$, $e$, $\phi$ and so on and can construct fractions for the approximation.

Installation

From PyPI

Simply use

$ pip install nerdyversary

to install this package in your environment.

From Source

To install nerdyversary from source, follow these steps below:

1. Clone the repository

   $ git clone https://github.com/rmnldwg/nerdyversary
   

2. Create a Virtual Environment (optional, but recommended)

   $ python3 -m venv .venv
   

   You should do this with an installation of Python 3.10 or later. And don't forget to activate the environment with

   $ source .venv/bin/activate
   

3. Use pip to install

   $ pip install -U pip setuptools setuptools-scm
   $ pip install .
   

Usage

Script

usage: nerdyversary [-h] [-v] [-d SPECIAL_DAY] [-s START] [-e END]
                    [--max-power MAX_POWER] [--factor-lim FACTOR_LIM]
                    [--format FORMAT]

Find beautiful nerdyversaries.

options:
  -h, --help            show this help message and exit
  -v, --version         Show the installed version and exit.
  -d SPECIAL_DAY, --special-day SPECIAL_DAY
                        Date of the special day in ISO format. (default: 2023-01-04)
  -s START, --start START
                        Date when to start with search in ISO format. (default:
                        2023-01-04)
  -e END, --end END     Date when to end the search in ISO format. (default:
                        2024-01-04)
  --max-power MAX_POWER
                        Largest exponent to consider for building the nerdyversaries.
                        (default: 5)
  --factor-lim FACTOR_LIM
                        Largest multiple of a symbol that is accepted. (default: 10)
  --format FORMAT       The output format that will be used by the `tabulate` package.
                        (default: simple)

The FORMAT argument must be one of the strings the tabulate package understands.

An example: The input

$ nerdyversary -d 2012-12-21 -s 2023-01-01 -e 2024-01-01 --format pipe --factor-lim 4 --max-power 3

will yield a markdown table that renders into the following:

Date	Days	Years	Expression
6. Jan 2023	3668	10.04	$\frac{e^{3}}{2}$
24. Feb 2023	3717	10.18	$\frac{5 e^{3}}{\pi^{2}}$
12. Jun 2023	3825	10.47	$4 \phi^{2}$
19. Jun 2023	3832	10.49	$\frac{5 \pi^{3}}{2 e^{2}}$
25. Jul 2023	3868	10.59	$\frac{5 \phi^{3}}{2}$
5. Nov 2023	3971	10.87	$4 e$
12. Nov 2023	3978	10.89	$\frac{3 \pi^{2}}{e}$
14. Dec 2023	4010	10.98	$\frac{3 \pi^{3}}{2 \phi^{3}}$

The symbols here are

• the golden ratio $\phi \approx 1.618\ldots$
• the number $\pi \approx 3.1415\ldots$
• Euler's number $e \approx 2.718\ldots$

When using this package as a library, arbitrary constants may be defined as symbols.
