End of Mathematics

Authors: August Lau
Comments: Pages.

Data is abundant but has few answers. Massive data challenges mathematics when no equation exists. Data processing has no universal operator but uses a combination of operators. Physical science has done well with formal rules and equations, typically low order equation and low dimensional space. Data science lives in high/infinite dimensional space where an object has many attributes. Finally, “point set topology” liberated us from the rigidity of differential calculus and extended our mind to perceive infinite/infinitesimal objects. Our response should be to embrace more data and more operators. We should be inventors of new mathematical tools to process and interpret data.

Interpolating Values in Code Space

Authors: Adam Bourne
Comments: 20 Pages.

A method is described for interpolating un-sampled values attributed to points in code space. A metric is used which counts the number of non-equal corresponding indices shared by two given points. A generalised interpolation equation is derived for nets, which is then applied specifically to code space. This interpolation equation is then solved in general for a set of given known sampled values in the space.

Division by Zero and Bh\={a}skara's Example

Authors: Saburou Saitoh, Yoshinori Saitoh
Comments: 10 Pages. In this paper, from an example of Bh\={a}skara, we will see the result $1/0=0/0=0$. {\bf This very simple and clear example will be very attractive for general people over mathematicians}.

In this paper, we will introduce the division by zero calculus and Bh\={a}skara's simple example which shows clearly both $1/0=0$ and $0/0=0$.
