2/3 and 1/3 of what?"
A rhetorical question - answer is 2(sqrt(1/Pi)).
But what is the significance of these values?

Here's the 2/3 to 1/3 math perspective:
2(sqrt(1/Pi))
= 1.1283791670955125738961589031215..
^2 = 1.2732395447351626861510701069801..
/2 = 0.6366197723675813430755350534900..
1.2732395447351626861510701069801..
+ 0.6366197723675813430755350534900..
= 1.90985931710274402922660516047..
/ 1.2732395447351626861510701069801..
= 0.66666666666666666666666666666667..
= 1.90985931710274402922660516047..
/ 0.6366197723675813430755350534900..
= 0.33333333333333333333333333333333..
