Resource refers to all the materials available in our environment which help us to satisfy our needs and wants. Resources can broadly be classified upon their availability — they are classified into renewable and non-renewable resources. They can also be classified as actual and potential on the basis of the level of development and use, on the basis of origin they can be classified as biotic and abiotic, and on the basis of their distribution, as ubiquitous and localised (private, community-owned, national and international resources). An item becomes a resource with time and developing technology. The benefits of resource utilization may include increased wealth, proper functioning of a system, or enhanced well-being. From a human perspective, a natural resource is anything obtained from the environment to satisfy human needs and wants. From a broader biological or ecological perspective, a resource satisfies the needs of a living organism (see biological resource).The concept of resources has been developed across many established areas of work, in economics, biology and ecology, computer science, management, and human resources for example - linked to the concepts of competition, sustainability, conservation, and stewardship. In application within human society, commercial or non-commercial factors require resource allocation through resource management.

Hi guys,
I am currently enrolled in the second year of a computer science engineering course. Over the last couple of years, I have become a fortunate prisoner to mathematical fascination.
I was always good at Maths but the schools I went to did not encourage much creativity and the teachers...
I have started a class on the analysis of calculus. We are three weeks in and have covered some basic set theory, fields and axioms, and now we are beginning induction. It is a very rigorous course and I hoping someone might know of some helpful resources that could aid me throughout it. Ideally...
I've been relying on Wikipedia and some other questionable sources for a basic understanding of these studies, and i don't think I should rely fully on these sources. If anyone can point me to a place that is reliable I would greatly appreciate it.
Hello,
I am struggling with vectors, and general problems tagged along with them. How can I get some more practice aside from my book? What are some trusted resources that work well? What is your personal experience with vectors? Are (were) they a challenging obstacle for you? What is the best...
Hi,
I just started college and was pleasantly surprised to see that a lot of my classmates know a lot about different engineering stuff. Some would know all the parts of a car and maybe how the ac worked etc... for me other than programming I was ashamed of how limited my knowledge of these...
Hi, I was just wondering if there were any good resources/sites for learning to plot and solve differential equations and any other math for that matter, specifically in Python? The physics program at ASU is great but we aren't really given any class time to learn how to program, it's all on our...

I am in need of a few suggestions on books to read on Physics for beginners! I am new to this field of science and want to learn more about it. Any online archives, textbooks, published articles, etc. are welcome!
What courses or physics topics would you like to see on the internet?
I want to make a physics course series. I want to make videos and other resources (like animations, simulations apps, and games). I want it to be on topics that don't have a lot of videos and resources, and there are people...
I been googling videos and notes regarding the sketching of geometric figures, such as: planes, solids, 3rd/ 2d geometric shapes. Could not find decent resources.
The reason i ask is that I am having a hard time picturing certain problems with my mediocre drawing skills and I also tutor so it...

Hello, I have been studying matrices and determinants recently and do not understand why certain things are done the way they are. Like, why is matrix multiplication defined the way it is.
I find that there are not enough proofs. Is there any book/article/video that any of you recommend to...
I am absolutely clueless when it comes to drawing free body diagrams. I think I understand the concepts but as soon as I see an unfamiliar system I have no idea what goes where.
Are there any resourcess that provide a large number of practice problems (with solutions) for drawing free body...
Hello I am currently in high school and my high school only offers one physics class, but physics has always fascinated me. So my question is what are some resources you all found helpful as you were entering the world of physics? (Websites, blogs, books, video channels, etc...)
My wife got me hang gliding lessons for Christmas, which I'm going to take this summer. In preparation I'd like to learn what I can about atmospheric behavior on scales of a few meters to a few kilometers. I've found small isolated sources with tidbits of information, but nothing with any real...
Hi, I'm an 8th grader (also called 2nd year hs here) who's really enthusiastic about physics. This is my first post, so I hope you're okay with me making some mistakes (I've been reading stuff on this forum for a while now, though). Physics is still 2 years ahead, and I've tried waiting but I...
I was just thinking of the first concurrency problem I encountered whereby you have multiple threads incrementing a shared variable ('int x').
Now, I understand the problem and how it is solved, but since int x is a shared resource only one thread can access it at a time, so no time at all is...
Hi, i have been struggling to find some good resources on variational principle , I have got an instructor in advanced quantum course who just have one rule for teaching students- "dig the Internet and I don't teach you anything".. So I digged a lot and came up with a lot reading but I need...
During the Physics GRE Subject Test there is no formula sheet given and none can be brought in. It is best to try and memorize these fundamental formulas.
Please feel free to link to other useful formula sheets.
All data is for entry level and are national averages. Please plug in your zip code and select a different career level for better precision of information.

Hi there, I was just wondering if anyone knows of any good materials, books, websites, Youtube users etc for me to teach myself Complex Analysis for school. Some good practice problems with answers and explanations would be wicked too. Thanks :)
I saw the samsung edge released and I thought it would be very cool if I learned how it works. So are there any patents, blueprints, etc. that is on the curved display technology? I want to see it for myself because it's cool.
Is there a way to see other patents or blueprints legally?
Hello, I was wondering what websites you would suggest for resources?
Physics, mathematics, programming(any language), and engineering?
By online resources I was thinking resources like wolfram mathworld. Any online resource as extensive as wolfram mathworld would be great.
I am self-studying Physics in the second year of my undergrad(too late i know) as I never really understood many basic concepts in my high school as clearly as i now do.
In my enthusiasm to teach myself Physics I bought a number of books but none seem on par with stuff described on many forums...
