Hey there! In this video, I’m diving into the intriguing question of how mathematics relates to the real world. This question has come my way quite a few times, even when I was teaching algebra to my kids. We often use math in our daily lives, whether it’s basic arithmetic or more advanced concepts like algebra.
Mathematics plays a vital role in various fields, especially engineering marvels that rely on calculus and algebraic equations. These equations are essential for understanding complex systems and even the fundamental nature of the world around us. I’m gearing up for some exciting discussions in domain 3, focusing on mathematical models and constructs.
We’ll explore security models like Bell-La-Padula, Biba, Clark Wilson, and Lipner. There are two ways to understand these models: one is to grasp their outcomes, while the other involves delving into the intricate mathematical foundations. While the latter can be complex and often presented in a rather dry, academic manner, I’ll do my best to make it engaging for you.
Before we dive deep into mathematical models, let me provide a brief answer to the fundamental question: What is the relevance of mathematics and mathematical models in our daily lives? If you look closely, you’ll realize that our world, from the vast universe to our planet Earth and our human experience, is governed by laws.
These laws can be broadly categorized into natural laws and man-made laws. Natural laws, like gravity, are based on principles, and these principles follow a logical structure. To understand these principles and the logic behind them, we use tools, and one of the most powerful tools we have is mathematics. It allows us to create concepts and mental models that help us comprehend the underlying logic of these principles. In essence, mathematics is the key to unlocking the laws of nature.
Take gravity, for example. By applying mathematical equations, we can calculate how celestial bodies like the sun, moon, and planets interact. Mathematics provides the bridge between the abstract principles of nature and our real-world understanding.
Another simple example is the number system. We’ve invented numbers to make sense of the discrete nature of objects around us. From counting mangoes to measuring distances in meters or masses in kilograms, mathematics is the foundation upon which we build our understanding of the world.
So, to sum it up, mathematics is the language that helps us decipher the laws of nature and create models that drive scientific discoveries, technological advancements, and the marvels of our modern world. In the upcoming videos, we’ll delve deeper into mathematical models, including the Bell-La-Padula (BLP) model, exploring sets, relations, and functions. There’s a lot of intriguing content ahead, so stay tuned! And for those of you preparing for the CISSP exams, best of luck – I’m here to help you navigate the complexities of these topics.
