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.
Hello everyone!
I have a question about a potential flaw I see in the scientific method, but I hope people will illuminate me, and convince me that science has no problem in the respect I might lament on.
What if a scientific premise in a deductive argument is based on an observation, and we...
I am currently a final-year undergraduate student whose primary major is Physics. I double major in Computer Science, and my grade is currently near-top in my department from a prestigious university (non-US, top in my country).
My research experience during undergrad has primarily been about...
So, I'm not on twitter but I just heard Sean Caroll say on his podcast that he's following science journalists on twitter and that he uses that to know when something interesting happens in science because these journalists will link to it. Do some of you do that also? I'd like to know who you...
My name is Joe,
I'm 36 years old and currently between work. I live in The city of Erie, Pennsylvania.
My interests are in the phields of electricity, physics, chemistry, and all engineering principles related. As I am only a high school graduate with no formal training, my education is self...
If you enjoy both physics/science and history like me, you may enjoy this video from the Royal Institution. It's about groundbreaking experiments (no theoretical physics); X-rays, particles etc.
I'm only 45 minutes in so I haven't seen the entire video yet, but I wanted to share it...
I just read Feynman's The Value of Science and really appreciated his perspective. We generally value art, literature, and poetry but if you want to do science for the sake of science people take offense. It takes years to build a foundation before you can appreciate it, so the general public...
When I went to college, more than 30 years ago, as far as I can remember, nobody was talking about the use of Occam's razor in science. Reading the works of past scientists, I rarely see them invoking principles of parsimony, let alone cite Occam's razor. Yes, Newton, Einstein, and few others...
I am currently in my final year of high school in India, and slightly confused as to which course I should take. I've always been interested in physics, and would eventually like to do research in quantum computing. I'm not sure whether to take a B.S. in Physics, or engineering (a BTech) in...
A new group of investigators are attempting something similar to Deur's work, which seeks to explain dark matter phenomena with general relativity corrections to Newtonian gravity is systems like galaxies. Deur's most similar publication to this one along these lines was:

I'm 27 and I'm currently attending an online university for compsci. I did the math recently and I won't get my degree until I'm almost 30. Is it still possible for me to find jobs once I graduate?
Does it have any career opportunities outside of academia? Metallurgical engineering is easily applicable and you can find jobs with it anywhere. But about nanoengineering bachelor's degree, what kind of jobs can I find?
I'm a physics graduate from Delhi University, India. Aspirant of Theoretical Physicist . Right now , cleared Clerk in Govt. of India exam. About to get Job. I want to go for some top notch college in USA/Europe for Graduate physics. But also interested in Computer Software Engineering. Want to...

Generally, we try to apply scientific knowledge in some manner to benefit humanity. Often the application requires some standards or precautions so that the applications will have maximum benefit and minimal risk. One such application was that of ionizing radiation. X-rays were discovered in...
Hi all, I just finished my undergrad degree in CS. I did reasonably well and would like to pursue a PhD at some point in the next 6 years, however I am not ready to do so immediately. I have taken a job as a software engineer and intend to work there for a year or two to save up some money.

Just about every science related you tube use this patronising expression such that it's almost de rigueur. I find it mildly irritating and distracting as I can hear it coming halfway through whatever they are saying. Everyone from Arvin Ash to Sabine (bee) Hossenfelder and everyone in between...
How do the rods and cones in your eyes work? I looked it up but didn't find any detailed explanation, and could we make them artificially to use like cameras?

Is self-nomination common for career awards in science and engineering? I was under the impression that nomination for awards is only by others but apparently self-nomination is an option too. Any PF member has an experience in this to share?
I am 18 and currently in the middle of taking a gap year from high school to college. I am going to college this fall, and I want to go into college with a better grip on what I want to do than I have now. I absolutely love physics, science, and math. I also have a huge attachment to the idea of...
Few things are disparaged so militantly on this forum as popsci: scientific literature written for a general audience.
"It's entertainment, not real science."
"They won't teach you any actual physics."
Such remarks are all too common - and, in my opinion, they are utterly misguided. I won't...
I succeded to do the first method, but I could not do the second one.
The first method:

Summary:: I need to learn the deepest information
I just started computer science. I have to learn computer basics and then what maths should I learn? What math should I learn after I've learned basic math?
A very "meta" idea crossed my mind today, and I'd like some feedback. Apologies in advance in case the half-formedness of said idea results in a meandering post.
The specific connection I made was that the creation-versus-evolution "debate" could be characterized, at its most basic, as the...

Hi,
I think that history shows a constant:
- nobody wants to die
- this introduces several versions of fiction (like religion)
- science is influenced by this fiction
Probably you can imagine several examples where the idea of immortality influenced or influences science? What do you think...
