Fresh variable
A "Fresh variable" typically refers to a variable in programming, mathematics, or logic that has not been previously used or defined in a given context. This concept is often utilized in various areas such as: 1. **Symbolic Logic**: In logic and formal proofs, a fresh variable is introduced to avoid conflict with existing variables. It ensures that the variable represents a distinct entity that does not interfere with other variables or expressions.
Hamish Robertson
Hamish Robertson does not refer to a widely recognized subject, figure, or entity as of my last knowledge update in October 2023. It could potentially be a common name or refer to someone in a specific context, such as an author, professional, or character in a story. If you can provide more context or specify what field or area you're asking about (e.g.

Here’s an overview of the main aspects: ### 1. **Nuclear Power Generation** The UK has a significant history with nuclear energy, starting with the opening of the first commercial nuclear power station, Calder Hall, in 1956.
Gröbner basis
A Gröbner basis is a particular kind of generating set for an ideal in a polynomial ring, which has desirable algorithmic properties that facilitate solving various computational problems in algebra, geometry, and number theory.
Hans Mark
Hans Mark is an American aerospace engineer, educator, and former government official known for his contributions to aerospace engineering and his leadership in various academic and governmental institutions. He served as the deputy administrator of NASA and held academic positions at several universities, including the University of California, Berkeley, and the University of Texas at Austin. His work has focused on areas such as aerodynamics, propulsion, and space systems.
Nuclear technology organizations vary by country, reflecting their distinct approaches to nuclear energy, nuclear research, and the regulation of nuclear materials. Below is a list of some key nuclear technology organizations by country: ### United States - **U.S. Nuclear Regulatory Commission (NRC)**: Regulates commercial nuclear power plants and other uses of nuclear materials. - **Department of Energy (DOE)**: Oversees the nation’s nuclear energy policy, including research and development (R&D).
Nuclear weapons by country
As of 2023, several countries are known to possess nuclear weapons. Here is a summary of nuclear-armed states and their estimated stockpiles: 1. **United States**: Approximately 3,750 nuclear warheads, including deployed, stored, and retired stockpiles. 2. **Russia**: About 6,375 nuclear warheads, making it the largest stockpile in the world. 3. **United Kingdom**: Roughly 225 nuclear warheads.
Harold Craighead
Harold Craighead is a prominent figure in the field of electrical and computer engineering, particularly known for his contributions to nanotechnology and biosensors. He has held positions at prestigious institutions, including serving as a professor at Cornell University. His research often focuses on developing innovative technologies for detecting biomolecules and analyzing biological systems at the nanoscale. His work has significant implications for medical diagnostics, environmental monitoring, and various applications in biotechnology.
Integer partitions
Integer partitions refer to the ways of expressing a positive integer as the sum of one or more positive integers. The order of terms in each sum does not matter; for example, the two sums \(4 = 1 + 1 + 1 + 1\) and \(4 = 2 + 2\) represent two distinct partitions of the integer 4.
Number theorists
Number theorists are mathematicians who specialize in the field of number theory, which is a branch of pure mathematics focused on the study of the properties and relationships of integers. Number theory encompasses a variety of topics, including: 1. **Prime Numbers**: Study of prime numbers, including their distribution, properties, and related theorems (such as the Prime Number Theorem).
P-adic numbers
P-adic numbers are a system of numbers introduced by the mathematician Kurt Hensel in 1897, which extends the concept of the usual rational numbers. They are constructed in a way that allows for a different notion of "closeness" between numbers, based on a chosen prime number \( p \). The core idea of p-adic numbers is to define a distance between numbers that is based on divisibility by a prime \( p \).
Squares in number theory
In number theory, "squares" refers to the squares of whole numbers. A square of a number is the result of multiplying that number by itself. For example, the square of 2 (written as \(2^2\)) is \(2 \times 2 = 4\), and the square of 3 (written as \(3^2\)) is \(3 \times 3 = 9\).
Theorems in number theory
In number theory, theorems are established propositions that are proven to be true based on previously accepted statements, such as axioms and previously proven theorems. Number theory itself is a branch of mathematics that deals with the properties and relationships of numbers, especially integers.
