Ansatzes – Definition & Meaning


Ansatzes is a term that is commonly used in mathematics and physics. It is a German word that has been adopted into English and has a very specific meaning in these fields. In this article, we will explore the definition and meaning of ansatzes, its origin, associations, synonyms, antonyms, and provide example sentences to help you understand its usage in context.


An ansatz is a mathematical or physical assumption that is made to simplify a problem. It is a starting point that is used to develop a solution. In physics, an ansatz is often used to describe the behavior of a system or the properties of a material. In mathematics, it is used to express a function or a set of equations.


The word ansatz comes from the German language and means “approach” or “starting point.” It was first used in the field of mathematics in the 19th century by mathematicians such as Carl Jacobi and Felix Klein. It was later adopted by physicists in the 20th century and is now commonly used in both fields.

Meaning in different dictionaries

According to the Merriam-Webster dictionary, ansatz is defined as “a mathematical assumption made to simplify a problem.” The Oxford English Dictionary defines it as “a preliminary or tentative hypothesis adopted as a basis for further investigation.” In both cases, the definition emphasizes the idea that ansatz is a starting point that is used to develop a solution.


Ansatzes are often associated with complex mathematical and physical problems that require a simplified approach to solve. They are also associated with the idea of approximation and estimation, as they are used to develop an approximate solution to a problem.


Some synonyms for ansatzes include hypothesis, assumption, conjecture, theory, and premise. These words all emphasize the idea of a starting point or a preliminary idea that is used to develop a solution.


Antonyms for ansatzes include fact, truth, reality, and certainty. These words emphasize the opposite of a starting point or a tentative hypothesis and instead suggest a concrete and established solution.

The same root words

The word ansatz comes from the German word “Ansatz,” which means “approach” or “starting point.” The root word “ansetzen” means “to set against” or “to put in place.”

Example Sentences

  1. The ansatz we used to solve the equation was a simplification that allowed us to find an approximate solution.
  2. The physicist made an ansatz about the behavior of the material based on previous experiments.
  3. The mathematician’s ansatz was a tentative hypothesis that needed further investigation to be proven.
  4. The ansatz we used to estimate the value of the function was accurate to within a certain margin of error.

Ansatzes are a crucial part of mathematical and physical problem-solving. They provide a starting point that simplifies complex problems and allows for the development of an approximate solution. By understanding the definition, origin, associations, synonyms, and antonyms of ansatzes, we can gain a better understanding of their role in these fields.
