Nice. They could be reduced further using the elctromagnetic potential.

Classical physics describes the behavior of objects at macroscopic scales and is based on a set of fundamental equations. Here are some of the most important equations in classical physics:

1. Newton's Laws of Motion:a) Newton's First Law (Law of Inertia): An object at rest tends to stay at rest, and an object in motion tends to stay in motion with the same velocity unless acted upon by an external force.b) Newton's Second Law: The force acting on an object is equal to the mass of the object multiplied by its acceleration. It can be written as F = m * a, where F is the force, m is the mass, and a is the acceleration.c) Newton's Third Law: For every action, there is an equal and opposite reaction. When object A exerts a force on object B, object B exerts an equal and opposite force on object A.
2. Law of Universal Gravitation (Newton's Law of Gravity):The force of gravitational attraction between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. Mathematically, it can be expressed as F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between their centers.
3. Laws of Thermodynamics:a) First Law of Thermodynamics (Law of Energy Conservation): Energy cannot be created or destroyed; it can only be transferred or converted from one form to another.b) Second Law of Thermodynamics: The entropy (disorder) of an isolated system tends to increase over time. It implies that processes in nature tend to move towards a state of higher entropy.c) Third Law of Thermodynamics: As the temperature approaches absolute zero, the entropy of a system approaches a minimum value.
4. Conservation of Energy:The total energy of an isolated system remains constant. It can change its form, such as from potential energy to kinetic energy or vice versa, but the total amount of energy remains unchanged.
5. Conservation of Linear Momentum:The total linear momentum of an isolated system remains constant if no external forces act on it. It can be expressed as the product of an object's mass and its velocity.
6. Conservation of Angular Momentum:The total angular momentum of an isolated system remains constant if no external torques act on it. Angular momentum is the product of an object's moment of inertia and its angular velocity.

These equations provide a foundation for understanding and predicting the behavior of objects in classical physics. However, it's important to note that at very high speeds or in extreme conditions, such as at the atomic or subatomic level, classical physics is no longer sufficient, and the laws of quantum mechanics or relativity come into play.

Also let's not forget Alpha Fuxx, Beta Buxx.

Even Feynman wasn't Blackpilled enough to add this elegant formula to his lectures.

Focus on your niche, these things take a lot of thought to move beyond basics and are time consuming, you should not delve into things that don't make a monetary sense, basic physics is a prerequisite for engineering nothing beyond that.

 

[Knajjd]

Nice. They could be reduced further using the elctromagnetic potential.

Can they? I don't know any physics. I've read an Engineering Mathematics book in the past.

One of the lectures Feynman says no one knows what an electron is and why it doesn't tear itself apart as like charges repel. The equations of physics can model but can't really explain what fields or particles are.

He subconciously knew it, he just didn't want to upset the bluepilled Physicscels.

Very true.

I was thinking of buying the books and working my way through them, for a cope, but realised it would take me 10 years and I might be none the wiser at the end.

Like you say, better to focus on money in.

It can be very engaging for the thoughtful, but it doesn't pay, thinking in speech can be very addictive, the secret behind stem.

 

[starcrapoo]

ahh yes I really liked classical physics. you can use trigonometry for the force equations and actually figure shit out.

it gets harder and harder from there. electromagnetism is hard but after that which is quantum mechanics, it gets incredibly hard.

What do you mean by "thinking in speech can be very addictive, the secret behind stem"?

I just have a vague notion of what you mean. Can you clarify a bit? Thanks.

Thought, there are two ways you can think, either in speech or in graphical imagination, stem subjects give you ample opportunities to use these faculties instead of just reading, it's the thought that makes men sit for hours together, maybe your experience differs but that's how I see it and have done it

It's a shame we aren't taught to think at school. Some schools do, but they are not state schools and cost a lot of money to attend.

I just read this on Disney's stock:

"We prefer to step aside, acknowledging meaningful uncertainty, and wait for further catalysts, as buying the dip has been a losing trade," Nispel said in a client note Wednesday, according to CNBC.

It's just a single sentence but has all sorts of critical thinking going on such as know your limits, be comfortable with uncertainty.

 

[based_meme]

It's awesome (in the true sense of the word) how so much complexity can be described so simply.
