因为圆周率是一个比值，圆周长和直径都是测量而来，只要去测量圆周长和直径，就不可避免要在空间去度量，而空间，全都是非欧空间。

The well known numerical method of approximating differential
quotients by quotients of differences is used in a novel context.
This method is commonly underestimated, wrongly.
The method is explained by an ordinary differential equation first.
Then it is demonstrated how this simple method
proves successful for non-linear field equations with chaotic
behaviour. Using certain discrete values of their integration constants,
a behaviour comparable with Mandelbrot sets is obtained.
Instead of solving the
differential equations directly, their convergence behaviour is analyzed.
As an example the Einstein-Maxwell equations are investigated,
where discrete
particle quantities are obtained from a continuous theory, which is possible
only by this method.
The special set of integration constants contains values identical with
particle characteristics.
Known particle values are confirmed, and unknown values can be predicted.
In this paper, supposed neutrino masses are presented.

Let $V$ be an asymptotically cylindrical K\"{a}hler manifold with asymptotic
cross-section $\mathfrak{D}$. Let $E_\mathfrak{D}$ be a stable Higgs bundle over $\mathfrak{D}$, and $E$ a Higgs bundle over $V$ which is asymptotic to
$E_\mathfrak{D}$. In this paper, using the continuity method of Uhlenbeck and Yau, we prove that there exists an asymptotically translation-invariant Hermitian projectively Hermitian Yang-Mills metric on $E$.

When a meromorphic vector field is given on the projective plane, a complete holomorphic limit cycle, because it is a closed singular submanifold of projective space, is defined by algebraic equations. Also the meromorphic vector field is an algebraic object. Poincare had asked, is there just an algebraic calculation leading from the vector field to the defining equations of the solution, without the
mysterious intermediary of the dynamical system.
The answer is yes, that there is nothing more mysterious or wonderful that happens when a complete holomorphic limit cycle is formed than could have been defined using algebra.
