why is physics so hard

If you haven't got the understanding, the intuitive mental model that captures all the rules (theory) that you know, then you will struggle to see your way to the solution. As my son is starting to take some AP courses in high school (so far bio and chem) I think about this a lot. and true understanding often boils down to an interest and curiosity. Physics C is especially tough because not only are you learning physics material, which can be hard, you also need to know calculus alongside it. Basically, of you define physics as determining dynamical equations —the laws of physics— from some observations —the experiments—, they prove that this problem is NP-complete. Differential equations require knowledge of calculus, which involves algebra and so on. Score of 3: Qualified 4. The reason why quantum physics is so hard to understand is that the whimsical names of discovered particles during the sixties simply adds to the confusion. electromagnetism theory) to the specific (e.g. That should do the trick! Physics formalizes many of the things that you have done for years. However, loving the subject does not imply that you will never have night terrors where you wake up screaming "Its a real job I tell you, its a real job". Yes — physics is hard, but it doesn’t mean it can’t be enjoyable. So, you were right when you said "You really just have to understand it.". They get surprisingly good reviews. That is not how physics supposed to be, and it is a pitty you are stuck in such a situation. One good place for beginners seeking inspiration is the set of lectures by Feynman. @fprime: that doesn't make it about physics, though. Why doesn't the UK Labour Party push for proportional representation? Let's take a step back in time and think about your first exposure to physics. We don't have a systematic approach to it, basically, all we do is just try. To answer that, you need to have a clear model in your head of what an electron is, how it interacts with electric fields, the idea that a particle follows a path defined by an equation of motion, the thought that the oscillation of the platform will change both the time taken and the minimum initial energy needed to reach the platform. But even after all this, physics remains to be one of the most challenging subject for many students, including myself. Yes — physics is hard, but it doesn’t mean it can’t be enjoyable. Can anyone recommend very good online lectures, preferably videos? Think of it like learning to play chess: You can learn the rules in an afternoon, they aren't that hard. I think this applies to most sciences (I've definitely experienced it in both physics, mathematics, computer science and electronics). I'm failing the class and i try so hard. I'm in a classical mechanics class now. What is an effective way to evaluate and assess employees on a non-management career track? The destructive one is the easiest to explain and usually the one on which a fair amount of time is spent. Others struggled, and had to work hard, but eventually figured out the material. That sure doesn't help the reputation of physics. site design / logo © 2021 Stack Exchange Inc; user contributions licensed under cc by-sa. It is basically the skeptical part of science, the one where you test one idea against another. However, when we get into the weird stuff like quantum mechanics or general relativity, the math can be easier to understand that then concepts! I think being good at undrgrad level physics has a very high correlation with being good at math word problems, so if you don't get a satisfactory answer here (on how to make it much easier), I'd ask the math group the same question about word problems. Or try asking questions here. To summarize: critique is always relatively easy, coming up with good ideas is the hard part. I don't have to need to study physics to know that touching a hot iron is a bad idea. Frame dropout cracked, what can I do? (Allied Alfa Disc / carbon). Before jumping to the statistics, let us first talk about how the exams are rated. Lv 7. That requires lots of practice. Once you can do that, your understanding should be high enough to enable you to work through problems that need the understanding of the theory, but for which a cookbook like approach (simply plug in equation XXX for problems of type YYY, almost never works). Let me try to expand on that. Why is it so hard to get students to learn even simple physics o_O !!' Sometimes knowing where to start a problem is tricky enough. When you learn something that explains a thing you've been wondering about, you no longer have to memorize. A lot has to do with I dont know what else to do at this point :(. For our exams, they even give us a formula sheet, with every formula and equation we can possibly need. We don't have this problem in other subjects like literature or history (unless you are taking it in another language). When doing research in Physics, you tend to do this to get an intuitive expectation, or prediction, of what will happen, and then you do an experiment to test it. Most of my fellow students were mystified by science and mathematics. Physics is the culmination of learning the endless language of mathematics and combining complicated concepts to solve complex problems. Answer Save. It seems you just cant 'memorize' things in this class, like you can with any other class. For others, it's a foreign language only understood by the geekiest lifeforms. But yet, even after all this, its not easy to do, but it should be. This will help you when meeting new problems to assign them to the correct framework, in my opinion of course. Physics is typically the first time that students use their math skills (which isn't easy in the first place) in an applied manner. AdamPA1006 Not reallllly. Nice! Or they just are willing to spend so much more time on working on the subject, giving up on many other activities, which of course forges experience. “It may be 20 years of work down the drain. The only people who, I would say, weren't cut out for physics were ones who didn't care enough to try to learn. But many students find it hard to study physics. That takes years of practice. Does physics education research support the idea that answer keys are bad? 0 Party less? You really just have to understand it. I had known it was coming—logically, if not emotionally. Just to clarify my school allows for us to do one science, 2 sciences, 3 sciences or a mixture of all 3 in double award. Watch how those who are good at it descibe how they solve problems, hopefully some of their thinking style can be learned. I do enjoy learning it, and I liked it a lot in the beginning. The relevant concepts involved may not have been properly explained to you in sufficient detail for you to manipulate them easily. And don't be fooled into thinking engineering will be any easier. The good news is that enjoying physics is much different than practicing physics. The best learning technique for me when I was learning it was to speedread the chapter in the text book, then take out lots of paper and derive all the formulas just taught -the speedreading was to get the gist of where you are trying to go to and a feeling for how to get there. And lately, I've just been so discouraged to study since no matter how hard I study, I do really bad on the tricky exams. I really like your descriptions of thickness, depth, breadth, etc. I need drivers for Linux install, on my old laptop, Because my laptop is old, will there be any problem if I install Linux? Formulas are (merely) a means of describing relations between physical quantities. How likely it is that a nobleman of the eighteenth century would give written instructions to his maids? Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Imagine taking a chemistry class in a language you don't speak. Anyway a lot of people in my class are telling me that I’ve made a mistake as physics and chemistry are both really hard as full subjects. Physics is interesting. And more importantly: is it justified? Reason #1 Physics is hard and there is no textbook or step-by-step guide First of all, besides the challenging and abstract physics laws, most local schools do not follow a comprehensive textbook or step-by-step guide. Feynman used the chess analogy a number of times, but not in this context. Why is physics so hard? The problem is: There are so many formulas which you can combine, rearrange and manipulate in oh so many ways that just knowing the formulas doesn't get you that far. To study for the exams, I do a BUNCH of practice problems from previous semester exams that they supply us with. But this teaches you nothing about how to be a good chess player. Few people understand the importance of background. Probably this is your problem with physics, that you have the detail tools and are missing the forest for the trees. Ubuntu 20.04 - need Python 2 - native Python 2 install vs other options? If you were lucky, you had an enthusiastic teacher who seemed way too excited about Newton's Second Law. Well @fprime, the first thing to realize is that physics is really friggin' hard and it seems to me that once you're over that hump you might actually end up enjoying it. But really, if we’re going to be honest, as scientists, if a member of the public asks us what is the meaning of our most basic theory of physics, I think we all have to say we don’t know.” :D. This is so true, and so well said. Why is A Level Physics So Hard? In other words, physics is not only hard, it is NP-hard ! It's a question about. I'd say sciences in general are difficult because of this. Just kidding. I’ve picked physics and chemistry for my gcse options. Watch pre-lecture video that explains the current chapter, and take notes on that. See http://www.amazon.com/s/ref=nb_sb_ss_i_6_15?url=search-alias%3Dstripbooks&field-keywords=schaums+physics&sprefix=schaums+physics. How to prevent pictures from being downloaded by right-clicking on them or Inspecting the web page? If you didn't encounter the problem in other sciences yet, it's because you are still at a more elementary study level in them as compared to physics. Experimental Physics often works in the opposite direction, starting from some specific experimental results, and coming up with a general theory to tie them together. Also, the course material was "dumbed down" and the problems were harder to solve in my opinion without vector calculus. It can certainly get overwhelming- all that math, all those equations. 'money conservation': income equals expenses plus savings). When quizzes or tests come around, the problems will need something more than the old "plug and chug." What you need is intuition and understanding as to which formulas relate to your problem and how you should relate them to get what you want. It lends to precise thinking and logic when describing the laws of nature...the physics and chemistry. Anyone can collect all the wrenches and sockets in the world, but the tools alone won't help you fix your car. Compared to O Level, there is a steep increase in the learning curve. So physics is hard if you want to do it. 5 years ago. My study routine goes a little something like this: I don't know what else to do at this point. We don’t know. Physics is about the ability to predict the outcome of scenarios. There are many reasons why students dislike physics such as; 1-Involvement of maths. Humans think though development of a picture of the minds eye. Have you considered using a book with very clear definitions and many worked examples, like Schaum's outline series? Suppose I tell you that an electron has been fired through an electric field towards an oscillating platform, and I want to know the time after which it will hit the platform, and what minimum initial energy I need. It is a difficult course, so if you're struggling a bit, it's good that you're having a bit of a challenge (as long as you're ultimately understanding the physics). Here is the most important lesson for physics students (and really all students). You have different camps pushing hard for their own interpretation. rev 2021.1.27.38417, Sorry, we no longer support Internet Explorer, The best answers are voted up and rise to the top. professor had been providing to my deaf perception all the semester. The way I see it, there are two aspects to the practice of science, there is a constructive one and a destructive one. Anyone notice the irony between the title and the tag? Andrew Smith. energy conservation) behind it. Either with formulas, simulation, or good old curve fitting. This intuition can only be built through experience, i.e. Using your mental model see, in your mind, what you think might happen in this specific circumstance. I will re-purpose it! Physicists May Have Finally Figured Out Why Knuckleballs Are So Hard to Hit All with the help of a ball-throwing robot Pitcher R.A. Dickey is well-known for his knuckleball. Physics Stack Exchange is a question and answer site for active researchers, academics and students of physics. Unfortunately it's not clear why despite the learning effort you seem not to perform so well at the exams. Chemistry has a reputation as a hard class and difficult science to master. It's not uncommon for people to cringe when they hear the word physics. Now, one might say that these two aspects are not necessarily exclusive to physics, which is true. Score of 1: No Recommendation 2. But some people have a desire to pop the hood, roll up their sleeves, and start turning the wrenches to the physics engine. Why it's Hard to Understand Quantum Physics. Make sure u get used to the wording of the questions because most of physics is understanding the question and context and applying the physics formulas correctly. Why don't video conferencing web applications ask permission for screen sharing? Physics gives us answers to all these questions. There's a reason why problems solvers are paid more than jobs only involving mundane labor. Here's a look at what makes chemistry so hard. That was the theme of George Musser ’s keynote talk at a seminar for science communicators held this week at the University of Leeds. Why isn't the constitutionality of Trump's 2nd impeachment decided by the supreme court? ... laughing so hard that we gather a … If you're good in computer science classes: Here it's the same. Sure, this could be said about many other subjects, but these skills can only be used with some pre-requisites. Edit: Although this seems like a general study question, its actually a very specific question. To many, math is hard enough, making physics seem really hard. Sorry if I'm not making any sense. The constructive or creative aspect is the hardest part. By Alex Spencer 28 December 2020. That's a question we all have different answers for. If As it currently stands, this question is not a good fit for our Q&A format. This is only natural. read more numerous hours of problem solving. We can come up with lots of ideas, but nature doesn't care about how creative we are, if the idea doesn't work it doesn't work. It seems like it should be so easy. Do the weekly homework, which itself is pretty challenging. Physics helps us to understand how the world around us works , from can openers, light bulbs and cell phones to muscles, lungs and brains; from paints, piccolos and pirouettes to cameras, cars and cathedrals; from earthquakes, tsunamis and hurricanes to quarks, DNA and black holes. I don't think this question belongs here. Physics 1 makes sure you really understand the concepts, there's none of that "plugging and chugging" into equations. Musser – who has written extensively on topics such as quantum entanglement and string theory – gave several reasons and here are a few that stuck in my mind. I'd say sciences in general are difficult because of this. On our exams, most questions are quantitative. My suggestion is to bear with it, until you discover some of the commonalities by yourself and find your own way of making sense of the world. Right at the top of my list of the top 10 hardest GCSEs, we have GCSE … If you find 1st year physics hard, it's only going to snowball from there. Physics is nearly the same thing, except the language is math. Science communicators like Neil Degrasse Tyson and Brian Cox have authored amazing books which allow any reader to learn about the conceptual side of physics. It's often useful if you can find an everyday analogy for it (e.g. In my experience, physics was only hard after I left high school because my "teacher" was a weirdo and didn't know how to teach, and I didn't take the initiative to learn everything on my own. Try studying together with other students (from whom you can learn). The kicker is that differential equations is just one tool used to solve a physics problem! There is an answer to your question in the form of a physics paper : Determining dynamical equations is hard by Toby Cubitt, Jens Eisert and Michael Wolf.
