We often hear knowledge is power. That's true but studying Physics told me that Knowledge can be entertainment as well.
When I started learning Physics instead of just studying it, I found how beautiful and exciting it could be exploring this fascinating universe.
Being a Physics graduate and...
I’m here to connect with others who appreciate the beauty of math and physics and to find support in spreading this knowledge to more people.
Looking forward to learning, sharing, and growing with this community!
I can basically explain everything, why the Universe exists, what it's doing, Dark Matter and connecting the forces together. I worked all this out when I was trying to make a spaceship and explore the Universe. I have mathematical proof which connects gravity to Quantum Mechanics etc. Or I had...
I am italian, i am studying civil engineer, i am looking forward to improve my knowledge and be in touch with everyone that is fascinating about how the universe works :)
Ancient knowledge is more scientific than politically whitewashed ideas of our present era. People often decide for themselves what is real based on who told them. Real science most come from experimental methods and vast research which only postulates but rarely proves anything and only...
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...
Hi.
I am Hauzen from South Korea.
I came here to gain a lot of engineering knowledge from this forum.
I want to be a competent engineer with a lot of your help.
I look forward to your kind cooperation :)
How much chemistry do I need to know as a theoretical physicist in order for this knowledge to be sufficient for research in any field of theoretical physics? It is also interesting to know how difficult the transition from theoretical to experimental physics is? Do experimental physics require...
Hi people,
It's been years I wanted to post this question here. I would like to build a zero knowledge proof that a given chess position contains at least one checkmate. I know that anything provable admits a zero k proof. I know about...
I hope this letter finds you well. My name is Daniel González Moreno, and I am writing to introduce myself as an independent researcher with a passion for knowledge and discovery.
While my formal education may lie in the arts rather than the sciences, my fascination with the mysteries of the...
I find lots of my friends that are excellent at math but dont know physics , cant solve physics tasks.
I think for physics is not enough to know math, you must understand concepts.
Sometimes is harder tool(math), sometimes is harder concept.
Here is video where Oxford mathematician solve...
I have long been gripped by an argument that I believe is profound, rooted in the science-literature dichotomy. It tends to favor one particular branch of knowledge, advocating an aut-aut (either pure science, or applied science) that devalues and demonizes the other. Unfortunately, in my...
Hello everyone,
I am very new to the concept of advanced math and am looking to broaden my knowledge.
I had sort of a vision involving the concept of swirling water and it has led me down the path of rotational energy. I am eager to learn
more and contribute if possible in the future to the...
I started this thread since there doesn't seem to be one about books on various topics meant for the inquisitive but non-expert person. These books might fill small niches in one's knowledge of our world. Sometimes we find a book that is just a lot of fun.
I just finished "A Short History of...
Summary:: I understand the consensus on PF about studying for knowledge and not merely for "cracking Semester Exams" but I urge you all to go through below thread before attaching to that feeling in my case.
Hi.
So I have my Exams on Intro QM approaching very soon, which will be a combination...
really confused at this. which is rule of thumb? some slides say heuristic is rule of thumb whereas others say factual knowledge is rule of thumb. the context of this is architecture/block diagram of expert system.
i think heuristic knowledge should be called rule of thumb. but i am not sure.
I need in my story some examples of previous knowledges or technology that were once kept suppressed in order to control the masses. For example. Flour (to keep people dependent on fruits or vegetables or produce)? Electricity? concept of Pressure? What can you think of? In modern times...
Hi all,
I'm interested in the interplay between condensed matter and high energy theory. I'm a bit more than half-way through peskin and schroeder (done with part II, RG and critical phenomena).
What I find out is that I'm still sorely lacking in ability to read any of the current research in...

I have been going through the sections in my Ron Larson Precalculus textbook and find that at least for the first 5 or 6 chapters, I can answer a lot of the questions except for a few selective problems. I will post those problems moving forward. No sense in posting questions I already know how...
How did you find PF?: Google Search

I am test my knowledge of differential forms and obviously I am missing something because I can't figure out where I am going wrong here:
Let ##C## denote the positively oriented half-circle of radius ##r## parametrized by ##(x,y) = (r \cos t, r \sin t)## for ##t \in (0, \pi)##. The value of...
Hi,
I want to make sure my understanding of calculating surface integrals of vector fields is accurate. It was never presented this way in a textbook, but I put this together from pieces of knowledge. To my understanding, surface integrals can be calculated in four different ways (depending on...
I'm hoping to see accounts of situations wherein a little (or maybe a lot) of scientific knowledge paid off.
I'll start with one that's really basic, but in my view rather amusing.
In the winter of '87 I was returning to Chicago, from DC where I'd been working on a USG contract (IBM mainframe...
I want to understand most physics papers, but I don't have much time to learn every Math subject.
When I was in college, I only took Calculus, Linear Algebra, and Statistics. I can't understand many Physics papers that interest me.

I need to be sure about a few things. Thanks for any replies.1) In HUP, it is impossible to know both the position and momentum of a particle. The more knowledge you gain of one defining parameter, the more you lose of the other. So, what I want to know, is if it is actually possible tobe %100...
Is it possible to have a solid premise and conclusion in a statement, only later through new knowledge have the conclusion become invalid (with the premise(s) still being solid?)
Organized science and many scientists are not as humble as some have suggested:The laws of the universe are named after the disoverers, almost as if Newton invented Gravity and Einstein devised relativity.They are no longer called "Natural Law of (name) discovered by (name), but Newton's Laws...
Something caught my eye about the symbol for Medicine a few years ago.The symbol is that of 2 snakes or parasitic worms wrapped around a staff that has wings a its top end.Certain explainations of this symbol claim that it represents an archaic method of removing parasitic worms from a person's...

Is it possible at this stage in our state of knowledge to have an intuitive mental image of the atom?I suppose it wouldnt make sense to think of it visually because for starters electrons are a wave / probability distribution.Wht about protons and neutrons? Is it possible to visualise them?
I was wondering... As time goes on will our knowledge of physics become more simple or complex? At the present, science (especially astrophysics and quantum mechanics) are getting more complex everyday (Dimensions, strings, more and more particles to name a few). Will Science become very...
At Yale one of the physics professors would test his undergraduates' general knowledge of the subject by inventing an outrageous machine (a la Rube Goldberg) utilizing most of the classical and modern aspects of physics. For a given input, what was the output, showing all equations, etc.?What...
I would like to see more information in our Profiles. For example, the first two fields I would like to see introduced into our Profiles would be 'Age' and 'Area of Knowledge' or something like that.I know there is an 'extra info' text box, but u cant enter more than like 25 letters into the...
