Ultimately, what it means is that a vector projection is nothing more than the compound of two vectors. An analogy. Two billiard balls approaching each other. Upon collision, if we were to consider only one of them, what is the new vector it results with, due to the impact, starting at the point of impact. Easy, eh? :)

Very easy to understand :D So a ball falling from the sky at an angle when it hits the projection would be the vector that the ball will "bounce" towards?

Correct :) To be pedantic, the "ball falling from the sky at an angle" is the ball and its vector details, the angle being the direction in 2D/3D space (depending on how you see it) and upon "impact" with another vector (even an immobile has a vector) results with a projection, again each one has a projection.

Apparently my thinking apparatus is having a little trouble today, because I don't see any connection between engineering, medicine and dance, other than that they all appear in your post.

The best lesson I ever had... I want you to observe an object falling through space, then , having observed, enable via an interaction, immediately, to interject a second object, freely, to interupt the ballistic path of the first object, and, by doing so, cessate the conclusion of its path, taking into consideration such divers data as freefall path, gravity, air resistance and procedural lagging and show, through empirical means, that such an interaction is both possible and, via completion, achievable, in a time frame that is shorter than that achievable by the frame available to that of concious thought. It was easy... Catch!

I am about to start University for a Computer Science degree however my maths skills are not great (GCSE level 2) as I haven't done A levels maths... Maths has always been a struggle for me as the tutors seemed more concerned on the "higher" students than "middle grade"... Can anyone recommend a on-line resource or book for learning some maths higher than GCSE level 2 as allot of algorithm books (especially game development books) contain lots of wonderful symbols and structure which I do not know (or know how to search for them as I do not know the names)? :-D
Well I'm pretty sure that GCSE maths will get you through the course, and if it helps I did A-Level maths and still have trouble understanding all the crazy symbols they throw in. Even knowing the symbols it's still a struggle to figure out what all of the variables are. I've still not found much use for any of the maths I learned at A-Level and it's all slowly slipping away. GCSE Physics and algebra on the other hand are most definitely useful.

When I did old fashioned O Levels I found it what is what they are doing at A Levels today. Serious slippage!

I done my Maths GCSE 3 years ago, I use very little of it however some simple 2D game physics (Velocity, Gravity, friction...) I can do. I have even managed to figure out a "Verlet rigid body" (ragdoll) without understanding the maths but I feel somewhat a cheat by doing it in software instead of its core mechanics ;P

And yet I need the maths more now that I am doing my degree in Evolutionary Biology than anything else I have ever done. Sure, as an accountant, I use a lot of Arithmatics, but it is only now I am doing a lot of set theory, ecological constaint mechanics and reproductive mathematics that all the shot I learnt a hundred years ago is becoming important.

I'm wondering what you think you'll need maths for in computer science? I did A-level Maths and Physics and Maths courses in my engineering degree, none of which I have ever needed in my programming career. Some basic arithmetic, algebra and trigonometry (an then only because I'm writing / supporting a CAD program) is all I ever required. (I used to work in real-time optimisation). Being able to read and understand English describing maths will get you further (you don't actually need to understand the maths). For instance, with the aid of the internet, I could probably implement any sort algorithm you care to mention, applying it to almost any problem, but I might not bother to actually figure out EXACTLY ho the sort works...

I have never needed maths in Accountancy, but now I am doing evolutionary biology I need maths. Odd, innit?

Well the CS course focuses on AI and Games Theory which I am sure I would need some decent mathematics greater than what I know to be able to "prove" theory's?

I have it too, its very awesome and flexible + bonus points for being surprisingly balanced :laugh: The story mode is very good and could even be classed as "Epic" (opinion). If you liked Command and Conquer (not tw 4 that was horrible I think) you will love this :-D

Reminds me of "Blast From the Past". The main character struggles to understand baseball, but finally "gets" it eventually. Guess it just takes some longer than others to play catch.

Well, Mathematics is a broad and beautiful subject. You'd have to be a bit more specific with your question to get a really good answer regarding a resource. I can suggest two things however. The first is that Maths, like anything, needs a lot of hard work, so much more so than intelligence, to be good at it. Intelligence makes the route shorter, but hard work gets you there all the same. So have at it with a brave heart :) The second, and I use this from time to time mostly for things other than Maths, is the OCW from MIT (Clickety[^]). This has several, some more advanced than you'd care or want, fantastic classes with quite a few having video lectures. After seeing some of those lectures, you can really understand why MIT is such a fine institution, the lecturers are excellent. There is one or more on Mathematics for Computer science, so you might want to check that one out first. Also, there are quite a few of us who are interested in Mathematics, I am one of them, who would gladly help out with anything specific.

Great site, Mustafa! :-D I checked it out a few years ago, but most of the course materials were missing. It's grown quite a bit, and the class materials are much more complete. A pity that they only offer one class in Power Systems Engineering... Not to worry, though. I still want to know more about designing steel structures, water and sewer systems, and reinforced concrete design. That should keep me busy for a few weeks. :-D

5'ed and seconded. I have watched the OCW videos for Linear Algebra by Gilbert Strang. His explanations are excellent!

Many years ago I needed to get Mathematics O level to get into university. I worked my way through 'Teach Yourself Algebra' and did every problem in it. (Teach Yourself... is (was?) a well known series in UK). Somewhere along the line it clicked what was going on - don't know why or how it just did. The lesson I drew from this was that I had to do mathematics to get it. Just reading books or attending classes was not enough. But I guess that's pretty much the same in all subjects - to get programming you need to program, not just read programming books. :)
