Science (from the Latin word scientia, meaning "knowledge") is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.The earliest roots of science can be traced to Ancient Egypt and Mesopotamia in around 3000 to 1200 BCE. Their contributions to mathematics, astronomy, and medicine entered and shaped Greek natural philosophy of classical antiquity, whereby formal attempts were made to provide explanations of events in the physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of Greek conceptions of the world deteriorated in Western Europe during the early centuries (400 to 1000 CE) of the Middle Ages, but was preserved in the Muslim world during the Islamic Golden Age. The recovery and assimilation of Greek works and Islamic inquiries into Western Europe from the 10th to 13th century revived "natural philosophy", which was later transformed by the Scientific Revolution that began in the 16th century as new ideas and discoveries departed from previous Greek conceptions and traditions. The scientific method soon played a greater role in knowledge creation and it was not until the 19th century that many of the institutional and professional features of science began to take shape; along with the changing of "natural philosophy" to "natural science."Modern science is typically divided into three major branches that consist of the natural sciences (e.g., biology, chemistry, and physics), which study nature in the broadest sense; the social sciences (e.g., economics, psychology, and sociology), which study individuals and societies; and the formal sciences (e.g., logic, mathematics, and theoretical computer science), which deal with symbols governed by rules. There is disagreement, however, on whether the formal sciences actually constitute a science as they do not rely on empirical evidence. Disciplines that use existing scientific knowledge for practical purposes, such as engineering and medicine, are described as applied sciences.New knowledge in science is advanced by research from scientists who are motivated by curiosity about the world and a desire to solve problems. Contemporary scientific research is highly collaborative and is usually done by teams in academic and research institutions, government agencies, and companies. The practical impact of their work has led to the emergence of science policies that seek to influence the scientific enterprise by prioritizing the development of commercial products, armaments, health care, public infrastructure, and environmental protection.
This is an extract from my letter of resignation from the forum:
My belief is that physics has taken a wrong turn, and what passes as science is nothing more than speculation without hard evidence. As a challenger to the accepted paradigms, I can understand how I have ruffled a few feathers...
From this week's digital edition of Scientific American:

Hi everyone!
I'm currently doing a Natural Science degree from the Open University. I've always been interested in Biology and Chemistry, but for the past few years I have started to become interested in Physics.
Hello everyone & thank you for letting me join your community. I am a high school science teacher in Minnesota, USA. I took over the classroom of a former physics/math teacher and have found all kinds of cool but old equipment. I primarily teach 9th grade physical science this year but that...
What's the difference in content between the two textbooks? International Adaptation and local edition
Principles of Physics: Extended, 12th Edition
Principles of Physics: Extended, International Adaptation, 12th Edition
It so hard to predict the future but are there any technologies from sci-fi movies or books that can’t happen in real life because it’s just completely impossible to create them? For now and even when we have more advanced science knowledge?
I was reading a Nature article by Dean Keith Simonton speaking about how science seems to have slowed and there really isn’t such a thing as a real genius anymore. He defines a true genius as “A real paradigm shifter. A Renaissance human who could completely change the way we understand the...
Hello everyone,

Hello! I joined because I am interested in how physics would intertwine with science based magical systems in books. I'm looking forward to learning a lot of new things and seeing how they would work with each other.
When I was nine years old, my dad left for what would be at least twenty-five years. Our family helped my mother raise me and my two younger brothers. One uncle who took on the role of surrogate father encouraged me to explore my interest in science to the limit a working-class family saw as our...
Hi, just found this on google so signed up.
Never too late to learn and with so many things going on around me I would like nothing more than to get to bottom of things and learn how things work, and how science impacts on us. Put off by science at school but now I find it totally fascinating...
I am currently a high school graduate trying to plan my career. I am aware this does not count much in the higher scale of things, but the one thing i was really interested in since my elementary school years has been science. And i always liked to imagine myself being a "scientist" when i was...
I'm new here and new in general to online forums. I'm a middle-aged guy who has been online for decades, but I just haven't used forums or social media very much.
I've always had a casual interest in math/science.
I had a question in my mind about PCBs.
Printed Circuit Board (PCB) is a non-conductive material with conductive lines printed or etched. Electronic components are mounted on the board and the traces connect the components together to form a working circuit or assembly.

Hello There,
I am MD Mushfique Farhan Nabir. I am a student and I love science. I decided to join Physics Forum to expand my existing physics knowledge, explore and share personal experiments. I am also a programmer.
Greetings,
I consider myself a teacher of science instead of a science teacher. I have experience teaching across many subject areas of science. This has enabled me to make connections across all of my differing content areas and share that with my students.
Am on the 'net' quite often and for extended periods of time perusing scientific sites and historical ones as well. Have BSCE degree from California State University, military experience,and other professional history.
Hello.
As instructed in the welcome message, I am here to introduce myself. I'm a Norwegian man in my forties with an above average interest in all kinds of science. I am youtube educated, so of course I know everything. Nah, just kidding. It is true that I am youtube "educated", so I have...

I am not a student, nor my everyday work is related to physics in any way. Basically I am an enthusiast on physics, and I have question whose answers I like to find.
I’ve heard at least a million times that you need to understand physics, but never actually understood in which way? When I study, I understand what the textbook says and how to apply it. But questioning why is it the way it is, usually confuses me and many times leaves me uncertain, I doubt it...
Hello,
I'm Logan Monday, and today was the first time I've ever visited this forum website before. It seems like a great platform, and a very knowledgeable community, so I couldn't help, but join in with it myself. I love science in general, but I'm very passionate about Computer Science...
Hiya!
I spend most of my free time thinking about physics and concepts. I want to strengthen areas where my knowledge is weak as I do not learn or digest information linearly. This presents some problems when trying to digest mathematical concepts or I probably would have felt inclined to study...
I'm making a big life change. Physics has always been a hobby of mine, but going back to college to finish a long overdue degree in physics. I'd love to find some social circles, particularly since I don't have any friends in this area yet.
As far as college, I'm in my 40s, so I'm probably...
I am interested in many subjects; history, physics, biology, art... well, just about everything. Why? Because the only truly useless knowledge is the knowledge you don't have. My interest in the sciences mainly derives from three sources: 1) my Dad's ongoing interest, as a layman, in sub-atomic...

Howdy from West Virginia!! If you would have told me 30 years ago that I'd be researching physics and math for fun, I would have said, "Are you high.... and by the way, what is physics?!?" I'm obsessed with all things science, and tickled by all things quantum. I became interested in science and...
Hello everyone,
I just joined the forum, after a bit of lurking on some various threads. It seems like a great forum. While I'm not a engineer, I am involved in various areas of construction, and I always try to back up my designs and work with as much science and engineering as I can. I hope...
I think the Enlightenment actually brought more darkness to science than light, using a few sparks to give the appearance of substance and intelligence.
These sparks have led to a number of theories that are not beeb proven yet becoming foundational to other knowledges. I know we need models...
Interesting article from the Economist. To me it seems a bit long on vague ideas and short on specifics, but it would be very good to get the right people at least talking about the problems that they point out.
The article:

How the physics and science limit our cosmos observation and link it to speed of light?
I could not find any equation, study or science that can support and limit our observation parameters.
Always looking for answers. Wanting to help my students discover the curiosity about the world. Would love to enable a desire for understanding all around us.
I would like to subscribe to a general science periodical (emphasis on physics would not go amiss) other than Scientific American that would explain new scientific discoveries and ideas in popular terms. A hard copy magazine best but digital okay too. Please, no defense of Scientific American...
I don't have much to say, at the time I had to drop out of university but I've always been passionate about science and I can't stop reading and thinking about it, especially physics and mathematics.Welcome everybody.
