I have a website and a blog.

I have, over the years, contributed a number of images to the Wikipedia.

The Fine-structure constant:

$\alpha ={\frac {e^{2}}{2\varepsilon _{0}hc}}\approx {\frac {1}{137}}$

where

$e$ is the elementary charge (1.602176634×10⁻¹⁹ C‍^[1]);
$h$ is the Planck constant (6.62607015×10⁻³⁴ J⋅Hz⁻¹‍^[2]);
$c$ is the speed of light (299792458 m⋅s⁻¹‍^[3]);
$ε$ ₀ is the electric constant (8.8541878188(14)×10⁻¹² F⋅m⁻¹‍^[4]).

Here is a useful public domain Lua function:

 function sPairs(inTable, sFunc)
   if not sFunc then
     sFunc = function(a, b)
       local ta = type(a)
       local tb = type(b)
       if(ta == tb)
         then return a < b
       end
       return tostring(ta) <
              tostring(tb)
     end
   end
   local keyList = {}
   local index = 1
   for k,_ in pairs(inTable) do
     table.insert(keyList,k)
   end
   table.sort(keyList, sFunc)
   return function()
     key = keyList[index]
     index = index + 1
     return key, inTable[key]
   end
 end
