Hahn is a relatively small impact crater located on the Moon's surface. It is situated in the lunar highlands and is characterized by its circular shape and relatively well-defined edges. Like many lunar craters, Hahn has been subject to the processes of erosion and degradation over time, leading to a more subdued appearance compared to newer craters. The crater is named after the German physicist and chemist Otto Hahn, who is known for his work in nuclear chemistry and physics.

An interplanetary dust cloud refers to the region of space within our solar system that contains tiny particulate matter, often referred to as interplanetary dust. This dust primarily consists of small particles, typically ranging from the size of a grain of sand down to sub-micrometer scales.
Circle packing is a mathematical concept that involves arranging circles within a given space, such that no two circles overlap and the arrangement satisfies certain criteria. The study of circle packing includes investigating how many circles of a given size can fit into a larger circle or how circles of different sizes can be arranged optimally.
Ellipsoid packing refers to the arrangement of ellipsoidal objects within a given volume in the most efficient way possible, often focusing on maximizing density—similar to how spheres can be packed. This concept arises in various fields, including mathematics, computer science, materials science, and physics. In three-dimensional space, the challenge of ellipsoid packing involves determining how to place ellipsoids (which can have different sizes and aspect ratios) to minimize the amount of unused space.
The strip packing problem is a classic optimization problem in the field of combinatorial optimization and computational geometry. The problem involves packing a set of items (usually rectangles) into a larger rectangular container, termed a "strip," with the objective of minimizing the height of the strip that is used. ### Problem Definition: 1. **Items**: You have a collection of rectangular items, each defined by its width and height.
As of my last knowledge update in October 2023, Muhammad Rafique is a mathematician known for his contributions to various fields within mathematics, including statistics, algebra, and differential equations. He may have published research papers, contributed to mathematical education, or been involved in academic institutions, but specific details about his work or achievements may vary.

He has served in various capacities within the party and has been involved in politics at both provincial and national levels. Haider has also been known for his contributions to social and political issues in Pakistan. His work often focuses on democracy, governance, and public welfare.
Sultan Bashiruddin Mahmood is a Pakistani nuclear scientist known for his work in the field of nuclear technology and engineering. He became widely recognized in the late 1990s for his involvement in Pakistan's nuclear program, particularly during the time when the country conducted its first successful nuclear tests in May 1998. Mahmood has also been involved with various scientific and technical organizations in Pakistan.
The term "Pakistani relativity theorists" likely refers to physicists or researchers from Pakistan who work in the field of relativity, particularly Einstein's theories of special and general relativity. These scientists may contribute to theoretical physics through research, publications, and teaching. Prominent figures in the field of relativity may include university professors, researchers at institutions, and those involved in the study of astrophysics, cosmology, and gravitational physics.
"Teenage Mutant Ninja Turtles" (2012) is an animated television series that aired on Nickelodeon, based on the iconic comic book characters created by Kevin Eastman and Peter Laird. The show features the adventures of Leonardo, Michelangelo, Donatello, and Raphael, who are trained by their rat sensei, Splinter, in the art of ninjutsu.
The Modular Neutron Array (MoNA) is a detector system designed for the study of neutron-rich nuclei and their decay processes, particularly in nuclear physics research. It is often used in conjunction with other experimental setups, such as the Fragment Mass Analyzer (FMA) or other particle accelerators. MoNA is composed of modular units of detectors that are arranged in such a way to provide high efficiency for detecting neutrons emitted from various nuclear reactions.

Pinned article: Introduction to the OurBigBook Project
Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.Figure 1. Screenshot of the "Derivative" topic page.
