Matrices: Why they even exist?

A brief coverage of the history of matrices from the point of view of Engineering Maths.

There have been so many mathematicians involved in the development of matrices, I've only named a few in this video that I feel contributed heavily to what you're exposed to in engineering maths.

Maths history is very important helps us understand the concept faster and better and helps kind of know why we are even studying it in the first place

the fact that you arent reading a script, or at least practised the damn thing and memorised, helps me listen. great vibes man! underrated channel

To me, matrices were boring and unnecessary until I found out that a matrix is just anothe way to present an algebraic straight line. ex 2x +4y = 5 can be presented in a 2 by 2 matrix. And if you have three variables its a 3 by three matrix etc. Human imagination is limited to understand 3 dimensional space, but matrices can deal wit unlimited numbers og dimensions. This mat is widely used in artificial intelligence where each connection between processors has to be calculated. Imagine a neural network with 2048 input processors in 98 rows, with each processor connect to each of the processors in the layer above. and Ai does this in split seconds. I do find this kind of interesting.

I listened to the audiobook on Calculus 'Infinite Powers', which really made Calculus make sense to me. Came here looking for how Matrices transformed and why they were used in history and their evolution through time

very good video sir..we really need to know why we learn this stuffs

[thetechnoking]

thanks, this helps to make me interested at actually learning

Very beautiful vedio and simple language of explanation 🌹🙏🌹

After watching 3b1b's *Essence of linear algebra* what I got is
*A Matrix is representation of a linear transformation between two sets of dimensions*
For example: from {carrot 🥕, tea ☕, rose 🌹} to {water 🌊, money 💰}

This is an excellent explanation of why matrices even exist. We home school, and we just started learning matrices in algebra. My son was very frustrated and asked, "Why do these even exist?" Thank you for answering his question.

It's worth adding that matrices were still quite an obscure topic even in the 1920's. Heisenberg's use of matrices in quantum mechanics did a lot to popularise them.

I just discovered that knowing all about the history of matrices makes me learn matrices much better.

[abdulaliulazim]

You didn't say whay they exist. you just mentioned the history

[diskgrinder]

Topness abounds. The enthusiasm for the history and the application is very

One of the reasons I didn’t do ‘A level’ maths. I wanted to like maths but couldn’t.

[ajjbs]

Thank you so much. What are they good for. This is my frist question

[samirjawalkar]

you make boring topics interesting and easy to understand ...

[churde]

Dude if you would level up with a catchy animation style these topics would kill
