Formal sciences are a fundamental pillar in the construction of human knowledge. Unlike natural or social sciences, these disciplines focus on the study of abstract systems and logical structures. But what does this really entail? What are the fields they cover and how do they influence our daily lives? In this article, we will unravel the mysteries of what formal sciences study, from their foundations to their most surprising applications.

1. What do formal sciences study: Definition and scope

Formal sciences are a set of disciplines characterized by their focus on abstract systems and the use of formal languages ​​to describe and analyze logical and mathematical structures. But what does this mean exactly?

Essentially, formal sciences are concerned with studying the form and structure of reasoning, regardless of the specific content to which it is applied. This distinguishes them from the natural and social sciences, which focus on observable phenomena in the physical or human world.

What are the main disciplines that make up the formal sciences? Traditionally, they include:

• Logic
• Maths
• set theory
• Computer's science
• Statistics
• Systems theory

Each of these areas provides unique tools and methods to analyze and understand reality from an abstract and formal perspective.

Why are formal sciences important? Their relevance lies in their ability to provide a precise and rigorous language that can be applied to a wide range of problems in other disciplines. From physics to economics, engineering and artificial intelligence, formal sciences provide the conceptual scaffolding needed to develop complex theories and models.

2. Logic: The art of valid reasoning

Logic is undoubtedly one of the fundamental pillars of formal sciences. But what exactly does it study? In a nutshell, logic deals with analyzing and systematizing the principles of valid reasoning.

Let’s think of logic as the “operating system” of our rational thinking. It provides us with the rules and structures to build solid arguments and detect fallacies. Isn’t it fascinating to think that there is a discipline dedicated to understanding how we think and reason?

Within logic, we find several main branches:

1. Propositional logic: Focuses on the relationships between simple propositions.
2. Predicate logic: Extends propositional logic to include quantifiers and predicates.
3. Modal logic: Studies concepts such as possibility and necessity.
4. Fuzzy logic: Works with degrees of truth, beyond the binary true/false.

How is logic applied in the real world? Its applications are surprisingly broad. From electronic circuit design to computer programming to analyzing arguments in philosophy and law, logic is omnipresent.

A concrete example: Have you ever wondered how search engines work? They use principles of logic to determine which results are most relevant to your query. It's logic working quietly behind the scenes to make our digital lives more efficient.

3. Pure Mathematics: Exploring Abstract Patterns and Structures

The pure mathematics They are the beating heart of the formal sciences. But what makes them so special? Unlike applied mathematics, which focuses on solving practical problems, pure mathematics is dedicated to exploring abstract patterns and structures for the sheer pleasure of intellectual discovery.

Have you ever marveled at the beauty of a fractal or the elegance of an equation? That sense of wonder is what drives pure mathematicians. They seek to understand the fundamental properties of numbers, shapes, and abstract relationships, without necessarily worrying about their immediate applications.

Some of the main areas of pure mathematics include:

• Abstract Algebra
• Number theory
• Geometry
• Topology
• Mathematical analysis

Each of these branches offers a unique perspective on the structure of the mathematical universe. For example, number theory, which studies the properties of integers, has led to fascinating discoveries such as Prime numbers twins or Goldbach's conjecture.

Do you think pure mathematics is too abstract to have any relevance in the real world? Nothing could be further from the truth! Many advances in pure mathematics have found practical applications decades or even centuries after their initial discovery. A classic example is number theory, which is today fundamental to cryptography and computer security.

4. Set theory: The basis of modern mathematics

Set theory is like the DNA of modern mathematics. But what exactly is a set and why is it so important? In simple terms, a set is a collection of well-defined objects. Sounds straightforward, right? However, this seemingly simple idea has revolutionized the way we understand and construct mathematics.

Did you know that set theory emerged in the late 19th century thanks to the work of Georg Cantor? His research on infinity and transfinite numbers laid the groundwork for a new way of thinking about mathematical structures.

Set theory provides us with a language and a conceptual framework to describe virtually any mathematical object. From natural numbers to the most complex functions, everything can be defined in terms of sets.

Some key concepts in set theory include:

1. Operations with sets (union, intersection, complement)
2. Relationships and functions
3. Cardinality (set size)
4. Zermelo-Fraenkel axioms

Have you ever wondered if there are different “sizes” of infinity? Set theory allows us to tackle fascinating questions like this. In fact, Cantor showed that there are infinities that are larger than others, an idea that challenges our everyday intuition.

How is set theory applied in the real world? Although it may seem abstract, its principles are fundamental in fields such as computer science, data and artificial intelligenceFor example, set operations are essential for database queries and machine learning algorithms.
