What is the first principle of Physics?

Physics is the foundation of science, yet physics also has a foundation, a first principle. A first principle is an elementary conjecture that is the starting point for a chain of reasoning. A first principle cannot be proved.

What is an example of a first principle in geometry?

The classic example is that of Euclid's Elements; its hundreds of geometric propositions can be deduced from a set of definitions, postulates, and common notions: all three types constitute first principles.

What are first principles in philosophy?

First principles are generally treated in the realm of philosophy known as epistemology, but are an important factor in any metaphysical speculation. In philosophy "first principles" are often somewhat synonymous with a priori, datum and axiomatic reasoning .

What is the physics approach of first principles?

In physics, a calculation is said to be from first principles, or ab initio, if it starts directly at the level of established laws of physics and does not make assumptions such as empirical model and fitting parameters.

How do you master first principles?

First principles thinking (also called reasoning from first principles) requires breaking down a problem into its fundamental building blocks, its essential elements, asking powerful questions, getting down to the basic truth, separating facts from assumptions and then constructing a view from the grounds up.

What is Elon Musk first principle?

For Musk, first principles thinking means boiling things down to "the most fundamental truths" and then reasoning up from there. Musk used the cost of batteries as an example. "People would say, 'Historically it's cost $600 per kilowatt-hour, and so it's not going to be much better than that in the future.

Now, what most people do, kind of the opposite of first principles thinking is called reason by analogy.

What is a prerequisite for physics 180?

PHYS 180 includes: Newtonian mechanics, planetary motion, rigid body rotation, harmonic oscillators, and waves. Calculus at the level of MATH 115 or equivalent is a prerequisite for PHYS 180. PHYS 180 is suitable for students with little or no physics background, but, of course, it will be less challenging for those who have previously taken high ...

What are the physics sequences at Yale?

The Yale Physics Department offers four two-semester introductory physics sequences, namely PHYS 170/171, PHYS 180/181, PHYS 200/201, and PHYS 260/261, any of which can be used towards an undergraduate degree in Physics. It is not always easy for students to identify the most appropriate physics sequence for them, and so the following is a guide to aid students and their advisors in the decision-making process. Whichever sequence you pick, you must take it in order, i.e. PHYS 170 before PHYS 171, PHYS 180 before PHYS 181, PHYS 200 before PHYS 201 and PHYS 260 before PHYS 261. We strongly recommend too that you stick in the same sequence throughout the entire year.

What is a phys 181?

PHYS 181 provides a comprehensive first course in electricity and magnetism. Taking MATH 120 previously or concurrently is recommended for PHYS 181. However if you cannot take MATH 120 please talk to the PHYS 181 instructor before deciding not to take PHYS 181. In deciding between PHYS 170/171 and PHYS 180/181, ...

What is the purpose of physics 180-181?

The goal of PHYS 180-181 is to provide a strong foundation in physics that will satisfy the physics requirements of other science and engineering majors at Yale, and for medical school, and to provide students the experience of thinking like a physicist.

Is math 120 a prerequisite for physics?

One of MATH 120 or ENAS 151 or MATH 230 or an equivalent course in multivariable calculus is a co-requisite or prerequisite for PHYS 260/261. A course in linear algebra is very useful for the quantum mechanics portion of PHYS 261, and is recommended but not a co-requisite. Since a strong foundation in physics is important, ...

What are the challenges of first principles?

The Challenge of Reasoning From First Principles. First principles thinking can be easy to describe, but quite difficult to practice. One of the primary obstacles to first principles thinking is our tendency to optimize form rather than function. The story of the suitcase provides a perfect example.

Why did Elon Musk use first principles thinking?

Musk used first principles thinking to break the situation down to the fundamentals, bypass the high prices of the aerospace industry , and create a more effective solution. First principles thinking is the act of boiling a process down to the fundamental parts that you know are true and building up from there.

In physics and other sciences, theoretical work is said to be from first principles, or ab initio, if it starts directly at the level of established science and does not make assumptions such as empirical model and parameter fitting.

A first principle is a foundational proposition or assumption that stands alone. We cannot deduce first principles from any other proposition or assumption.

The Coach and the Play Stealer

My friend Mike Lombardi (a former NFL executive) and I were having dinner in L.A. one night, and he said, “Not everyone that’s a coach is really a coach. Some of them are just play stealers.”

Authority

So much of what we believe is based on some authority figure telling us that something is true.

Techniques for Establishing First Principles

There are many ways to establish first principles. Let’s take a look at a few of them.

Examples of First Principles in Action

So we can better understand how first-principles reasoning works, let’s look at four examples.

Employing First Principles in Your Daily Life

Most of us have no problem thinking about what we want to achieve in life, at least when we’re young. We’re full of big dreams, big ideas, and boundless energy. The problem is that we let others tell us what’s possible, not only when it comes to our dreams but also when it comes to how we go after them.

Conclusion

The thoughts of others imprison us if we’re not thinking for ourselves.
