Key Differences
A postulate serves as a foundational element in mathematical and logical theories, assumed to be true without requiring empirical evidence. It is used to build upon and develop further theorems or principles. On the other hand, a hypothesis is a speculative statement, formulated on the basis of limited evidence as a starting point for further investigation. It is an essential part of the scientific method, intended to be tested by experimentation or observation.
Postulates are accepted as true within their specific frameworks, providing the base from which logical or mathematical reasoning proceeds. They are not subject to verification or falsification through physical experiments. Conversely, a hypothesis must be inherently testable; it is formulated with the intention of being either supported or refuted through empirical evidence, playing a critical role in advancing scientific knowledge.
In mathematics, postulates are used as given truths that serve as the foundation for a body of work, such as Euclid’s postulates in geometry. Hypotheses, however, are prevalent in scientific disciplines, where they precede experiments designed to test the validity of the proposed predictions or explanations.
While postulates are static, serving as steadfast starting points for theoretical exploration, hypotheses are dynamic, evolving with new data and insights. The success of a hypothesis is measured by how well it withstands tests and experiments, leading to its acceptance, modification, or rejection.
Both concepts, despite their differences, are integral to the advancement of knowledge. Postulates underpin theoretical frameworks, allowing for the development of coherent and logical structures, whereas hypotheses drive the empirical investigation, facilitating the expansion of scientific understanding.

To propose as a hypothesis or explanation

Hypothesis
(sciences) Used loosely, a tentative conjecture explaining an observation, phenomenon or scientific problem that can be tested by further observation, investigation and/or experimentation. As a scientific term of art, see the attached quotation. Compare to theory, and quotation given there.
Postulate
To assume as a premise or axiom; take for granted.
Hypothesis
(general) An assumption taken to be true for the purpose of argument or investigation.
Postulate
(Archaic) To make claim for; demand.
Hypothesis
(grammar) The antecedent of a conditional statement.
Postulate
Something assumed without proof as being self-evident or generally accepted, especially when used as a basis for an argument
"the postulate that there is little moral difference between the superpowers" (Henry A. Kissinger).
Hypothesis
A supposition; a proposition or principle which is supposed or taken for granted, in order to draw a conclusion or inference for proof of the point in question; something not proved, but assumed for the purpose of argument, or to account for a fact or an occurrence; as, the hypothesis that head winds detain an overdue steamer.
An hypothesis being a mere supposition, there are no other limits to hypotheses than those of the human imagination.
Postulate
A fundamental element; a basic principle.
Hypothesis
A tentative theory or supposition provisionally adopted to explain certain facts, and to guide in the investigation of others; hence, frequently called a working hypothesis.

Common Curiosities
Is a postulate always true?
Within its theoretical framework, a postulate is accepted as true, but this acceptance is context-dependent and not based on empirical evidence.
What distinguishes a postulate from a hypothesis?
A postulate is an assumed truth fundamental to a theory, not requiring proof, while a hypothesis is a testable prediction that must be empirically verified.
What role does experimentation play in testing hypotheses?
Experimentation is crucial for testing hypotheses, providing the evidence needed to support or refute them.
How does a hypothesis contribute to scientific research?
It serves as a basis for designing experiments and observations, guiding scientific inquiry and knowledge expansion.
Are all mathematical statements postulates?
No, only foundational statements assumed without proof are postulates; other statements, like theorems, are proved based on postulates and previously established theorems.
What makes a good hypothesis?
A good hypothesis is testable, falsifiable, based on existing knowledge, and specific enough to guide the research process.
Why are postulates important in mathematics?
They provide the foundational truths from which logical and mathematical reasoning and developments proceed.
Can a hypothesis become a postulate?
Typically, no. Hypotheses are testable and subject to change based on evidence, whereas postulates are foundational assumptions within their theoretical frameworks.
Can a hypothesis be proven?
Scientifically, hypotheses can be supported or refuted but are rarely considered proven due to the possibility of new evidence emerging.
What happens if a postulate is found inconsistent?
In theoretical frameworks, an inconsistent postulate would necessitate a reevaluation of the theory, but this scenario is rare due to the fundamental nature of postulates.
Why can't a hypothesis be a foundational assumption like a postulate?
Because a hypothesis is inherently speculative and meant to be tested, whereas a postulate is accepted as a foundational truth not subject to testing.
How do postulates and hypotheses differ in their application?
Postulates are applied as given truths in theoretical contexts, whereas hypotheses are applied in experimental and observational research settings.
What is the significance of hypotheses in developing theories?
Hypotheses are essential for developing theories as they guide the research that tests and refines scientific ideas.
Can the failure to disprove a hypothesis be considered a success?
Yes, if a hypothesis withstands rigorous testing and is not disproved, it is often considered to be supported, though not unequivocally proven.
How do scientists respond when a hypothesis is disproved?
Disproving a hypothesis leads to its modification or rejection, prompting further inquiry and potentially leading to new hypotheses or insights.
