[@cremebrulee2484]

I learned vectors in physics but not maths. I got the basic concept but not the notation so this clears it up nicely.

[@CosmicComputer]

This was SPECTACULAR! Please, please continue with the trig intro in the next video! This is an outstanding resource and you’ve put a lot of care into this! Thank you! I think it would be really awesome to take some of these concepts straight into unity through code later in the series and see the practical implications as well. This is so good man!

[@FloatyMonkey]

Thanks man, I just started working on the Trigonometry video. The idea of translating some concepts into code sounds interesting to me. Could you give an example of how you see this in concrete terms?

[@CosmicComputer]

FloatyMonkey could be interesting to see, and I know unity has built in functions for a lot of this, but for like finding distance between a player and enemy for ex., or a grenade throw with a parabola etc. Just things of that nature, it would be in keeping with the more introductory nature as well. Really excited for the next video!

[@HopDubstep]

You're a fantastic teacher. I liked how you demonstrate a concept with care to the progression of thought as to what the next thing to think about should be that creates a "smooth" / natural unfolding of what it is. You remind me of Feynman in this way and It's great. This was easier than I expected for me to follow.

I was needing a refresher and this was absolutely great... you just earned a new sub.

[@rabbitcreative]

2:50 I just got into an argument with a math-teacher (geometry) about exactly this. Sal of Khan Academy describes vectors using (x, y) notation, and something doesn't sit with me, telling me that a vector is direction + magnitude, and then using (x, y) to describe it. What you said-demonstrate from 2:50 - 2:59 is precisely what I want to see-hear. I want to see more of a lead-up to that though. Those 9-seconds I think should be like 30-seconds, or something, because what you did there is CRITICAL for language.

[@winexhd9373]

I think it is important to consider, perhaps a more abstract, but relevant point to make, to an introduction to vectors. I will start off with a joke. A mathematician, a computer scientist, and a physicist were hanging around in the cafeteria of their university. A student approaches the three and asks "What is a vector?". Surely, as masters of their fields, they can answer this seemingly basic question. The computer scientists speaks, "A vector is just a single columned matrix, like an array almost". The physicist smiles a little bit, perhaps with a touch of arrogance, and speaks, "You are partially correct but not completely, sure a vector can be represented as a matrix, but the original thing itself is an arrow". After much back and forth between the physicist and the computer scientist on what is the true essence of what a vector is, they turn to the mathematician for clarification. A mathematician says "Both of you are partially correct, but none of you are completely right". And then he walks away. I guess the point is that what does it mean for a thing to be something? Perhaps that is a deeper question from epistemology which I will try not to get into. A mathematician may suggest that a vector is anything that satisfies the "vector axioms" and operates "vector-ally". This seems like a circular definition so I will try to make it more clear. Any object, any thing, any concept, that can satisfy the vector axioms, is a vector. It may not have to have any physical significance, although to a physicist, it almost always does. But if a computer scientists wants to use vectors to represent non-physical such as the parameters of sensitivity of an AI model, then he may do that. In that case, an arrow may represent the AI's sensitivity vector, but it's physical representation serves more of a visual representation of a concept, rather than maybe being an actual thing.

[@Velorant2]

Vectors are mathematical entities used to represent quantities with both magnitude and direction. They play a crucial role in various fields, including physics, computer science, and engineering. Here's a brief overview: 1. **Definition:** A vector is often denoted as an ordered set of numbers, represented by an arrow. It has both magnitude (length) and direction. In 2D space, a vector might be written as \( \langle x, y angle \), and in 3D space as \( \langle x, y, z angle \). 2. **Components:** Vectors can be broken down into components along coordinate axes. For a 2D vector \( \langle x, y angle \), the components are \( x \) and \( y \). 3. **Magnitude:** The magnitude of a vector \( \mathbf{v} \) is denoted by \( |\mathbf{v}| \) or \( \|\mathbf{v}\| \) and represents its length. For a 2D vector \( \langle x, y angle \), the magnitude is given by \( \sqrt{x^2 + y^2} \). 4. **Direction:** Vectors have a direction, often measured as an angle with respect to a reference axis. 5. **Vector Operations:** - **Scalar Multiplication:** Multiply a vector by a scalar (a single number). - **Vector Addition:** Combine two vectors component-wise. - **Dot Product:** A scalar product that involves multiplying corresponding components and summing them up. - **Cross Product:** Applies to 3D vectors and results in a vector perpendicular to the plane of the original vectors. 6. **Applications:** - **Physics:** Used to represent forces, velocities, accelerations, etc. - **Computer Graphics:** Vectors represent points, directions, and transformations. - **Engineering:** Applied in structural analysis, fluid dynamics, and electrical circuits. 7. **Unit Vectors:** Vectors with a magnitude of 1 are called unit vectors. In 2D, the standard unit vectors are \( \mathbf{i} = \langle 1, 0 angle \) and \( \mathbf{j} = \langle 0, 1 angle \). Understanding vectors is essential for solving problems involving motion, forces, and various other physical phenomena.
