An abacus is a simple counting tool used for performing arithmetic calculations. It consists of a frame holding a series of rods or wires, each strung with beads or disks that can be moved. The design and configuration of the abacus can vary, but it typically allows users to represent numbers and perform basic operations like addition, subtraction, multiplication, and division. The abacus has ancient origins and has been used in various cultures, including the Chinese, Greeks, and Romans.
The Chinese multiplication table, often referred to as the "Chinese multiplication chart," is a method used to teach multiplication in a visual and organized way. It is similar to a standard multiplication table but is typically structured differently and may incorporate elements of Chinese numerology or cultural significance. In a Chinese multiplication table, numbers are arranged in a grid format with one set of numbers listed across the top (representing the multiplicands) and another set of numbers listed down the side (representing the multipliers).
András Gyárfás is a Hungarian mathematician known for his contributions to combinatorial geometry and graph theory. He has published numerous papers and is recognized for his work in areas such as extremal combinatorics and the study of geometric configurations. Gyárfás has also been involved in various collaborative research projects and has organized conferences related to mathematics.
John Riordan (1905–1982) was an American mathematician known for his work in combinatorics, generating functions, and number theory. He made significant contributions to the field, particularly in the areas of combinatorial methods and the study of special functions associated with mathematical sequences.

The term "Jewish biophysicists" refers to biophysicists who identify as Jewish, either culturally or religiously. Biophysicists study the physical principles underlying biological processes, often integrating techniques and concepts from physics, chemistry, biology, and engineering to understand the molecular mechanisms of life. The Jewish community has made notable contributions to various fields of science, including biophysics.
