Jan van Deemter is a Dutch chemist known for his significant contributions to the field of chromatography, particularly in the context of analytical chemistry. He is best recognized for formulating the "Van Deemter equation," which describes the relationship between the efficiency of a chromatographic separation and various factors affecting that efficiency, such as the linear velocity of the mobile phase and the characteristics of the stationary phase.

Japanese amber, known as "Kanto amber" or "Katsuura amber," is a type of amber found primarily in Japan, particularly in the Kanto region and parts of the Chiba Prefecture. Amber is fossilized tree resin that has been preserved for millions of years, often showcasing a variety of inclusions such as insects, plant material, and air bubbles. Japanese amber is typically characterized by its rich colors, ranging from yellow to orange and brown.

In physics, "jerk" is defined as the rate of change of acceleration. It is the third derivative of position with respect to time, or the derivative of acceleration with respect to time. Mathematically, jerk \( J \) can be expressed as: \[ J = \frac{da}{dt} \] where \( a \) is acceleration and \( t \) is time.

Johann Benedict Listing (1808-1882) was a German mathematician known for his significant contributions to the fields of topology and geometry. He is particularly noted for being one of the founders of topology, a branch of mathematics that deals with the properties of space that are preserved under continuous transformations. Listing introduced several important concepts, including the idea of "topological properties" and the distinction between different types of geometrical figures.
