How do I place the seat back 20 cm with a full suspension bike? Ubuntu 20.04 - need Python 2 - native Python 2 install vs other options? An example of the above can be with diaelectrics, when you have a materiel inside a capacitor. Physics is about the ability to predict the outcome of scenarios. But some people have a desire to pop the hood, roll up their sleeves, and start turning the wrenches to the physics engine. 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. A lot has to do with The destructive one is the easiest to explain and usually the one on which a fair amount of time is spent. Lv 7. 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.” For some, it resurrects thoughts of memorizing equations and then desperately manipulating them to solve problems (which is not what you should do). Does physics education research support the idea that answer keys are bad? When you learn something that explains a thing you've been wondering about, you no longer have to memorize. 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. Yes — physics is hard, but it doesn’t mean it can’t be enjoyable. This intuition can only be built through experience, i.e. This is unlike secondary schools which follow a more structured materials for teaching. I don't know how helpful this group will be, we are probably a selfselected subgroup whose natural intuitions were such that physics was easy (at least up until some advanced level, when the math got challenging). Sure, this could be said about many other subjects, but these skills can only be used with some pre-requisites. Yes — physics is hard, but it doesn’t mean it can’t be enjoyable. From the very first day of physics, I sat in class and understood nothing. 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. Sometimes knowing where to start a problem is tricky enough. (Allied Alfa Disc / carbon). Why isn't the constitutionality of Trump's 2nd impeachment decided by the supreme court? The kicker is that differential equations is just one tool used to solve a physics problem! 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. Sloppy logic and thinking are unforgivable in physics. Nature is a harsh mistress, and that's why physics is so difficult. 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. I had known it was coming—logically, if not emotionally. Watch pre-lecture video that explains the current chapter, and take notes on that. 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. 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. So, you were right when you said "You really just have to understand it.". In other words, physics is not only hard, it is NP-hard ! That's a question we all have different answers for. I'm failing the class and i try so hard. Before jumping to the statistics, let us first talk about how the exams are rated. Score of 5: Extremely Well QualifiedThe advantage of taking AP Physics C exam is that many colleges grant credit and placement depending on their cut-off score. Can anyone recommend very good online lectures, preferably videos? 'money conservation': income equals expenses plus savings). It only takes a minute to sign up. You can't just memorize it, you have to understand it. Why isn't SpaceX's Starship "trial and error" development strategy an open source project? 5 years ago. Physics is hard because it is precise and rigorous when done correctly. Feynman used the chess analogy a number of times, but not in this context. 7 Answers. Why is it so hard to get students to learn even simple physics o_O !!' Then the exam scores came back and I hated it :( Where can I find these lectures? I'm in a classical mechanics class now. But many students find it hard to study physics. Formulas are (merely) a means of describing relations between physical quantities. By Alex Spencer 28 December 2020. electromagnetism theory) to the specific (e.g. Bull fvcking sh!t. Let's take a step back in time and think about your first exposure to physics. I just know it tends to make the difference between being miserable cramming things into my head and working hard learning to understand something. Six months and no social life later you might start finding physics a lot easier and also a lot more different than what you expect. professor had been providing to my deaf perception all the semester. Now, being told to "be more interested" is hardly help, and I'm sorry for that. Even when you take away all the math, physics can still seem hard. Is this true. And don't be fooled into thinking engineering will be any easier. Below is the 5-point scale scoring for any AP exam as mandated by the CollegeBoard: 1. Why is quantum physics so hard to write about? “It may be 20 years of work down the drain. Physics is typically the first time that students use their math skills (which isn't easy in the first place) in an applied manner. Let me try to expand on that. In fact, despite computers' ever-increasing performance, they still can't solve some of the most cutting-edge physical problems today. I realize classes have a tendency to kill these things (even when done right, because you're now doing something because you have to), but I think it's worth the effort to try and rekindle your true interest. Hang in there, it gets only beter from here! 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. Here is the most important lesson for physics students (and really all students). physics is not hard ,we think it as hard ,if other students gets high credit in physics in our class, why we think as harder,we should love it,we should learn this subject to improve our brain… To summarize: critique is always relatively easy, coming up with good ideas is the hard part. So my real advice is this: There will always be courses that don't interest you. Great analogy... for Physics AND programming. energy conservation) behind it. This is only natural. If you find 1st year physics hard, it's only going to snowball from there. It's not uncommon for people to cringe when they hear the word physics. The constructive or creative aspect is the hardest part. Physics is the culmination of learning the endless language of mathematics and combining complicated concepts to solve complex problems. That's why the shorthand language for physics, and the other hard sciences, is math. And try to find out where your exam answers differ from the correct answers. It's not really about physics, it's about the way people think and learn. The problems that describe our everyday life are reasonably easy to conceptually understand. That should do the trick! The underlying principles a few basic ones, but to use them you required to understand higher lever math, so to make it "easy", basic physics classes boil it down to a cookbook method. For our exams, they even give us a formula sheet, with every formula and equation we can possibly need. Just kidding. Frame dropout cracked, what can I do? I had the tools, because I had solved all the problems, but not the large picture. motion of an electron through an electric field). Right at the top of my list of the top 10 hardest GCSEs, we have GCSE … Score of 1: No Recommendation 2. Also, before applying a given formula you must check whether the assumptions made when deriving it are fulfilled in a given problem. That requires lots of practice. It's a question about. Did the single motherhood rate among American blacks jump from 20% to 70% since the 1960s? 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. For those you'll just have to cram it in. That sure doesn't help the reputation of physics. I just don't get it. 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. It's not enough to know what a for-loop is and how it works to become a good programmer. See http://www.amazon.com/s/ref=nb_sb_ss_i_6_15?url=search-alias%3Dstripbooks&field-keywords=schaums+physics&sprefix=schaums+physics. 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. 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). Unlike English, math requires students to build off of previous concepts. I don't have to need to study physics to know that touching a hot iron is a bad idea. 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. So why would anyone want to learn physics? I think this applies to most sciences (I've definitely experienced it in both physics, mathematics, computer science and electronics). Furthermore, the material tested in Physics C is much more in-depth than Physics 1 or 2 (or the old Physics B). We don't have a systematic approach to it, basically, all we do is just try. Why it's Hard to Understand Quantum Physics. Physics is centered around developing problem-solving skills and harnessing them in new environments. What can i do! Humans think though development of a picture of the minds eye. How was I able to access the 14th positional parameter using $14 in a shell script? I literally go over and do 5 old exams, one question at a time, and I understand everything perfectly-at least I think I do, until the REAL exam comes around, and I do absolutely terrible. GCSE Further Maths. Physics gives us answers to all these questions. I think the biggest thing about physics, is its mostly about a mode of thinking, and secondarily about the detailed material. 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. Few people understand the importance of background. Now, one might say that these two aspects are not necessarily exclusive to physics, which is true. Sorry if I'm not making any sense. Either with formulas, simulation, or good old curve fitting. So why would anyone want to learn physics. rev 2021.1.27.38417, Sorry, we no longer support Internet Explorer, The best answers are voted up and rise to the top. Or try asking questions here. Math and physics felt natural. 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. So physics is hard if you want to do it. Score of 4: Well Qualified 5. Why I love ragdoll physics. 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. When quizzes or tests come around, the problems will need something more than the old "plug and chug." Think of it like learning to play chess: You can learn the rules in an afternoon, they aren't that hard. I do enjoy learning it, and I liked it a lot in the beginning. Physics 1 makes sure you really understand the concepts, there's none of that "plugging and chugging" into equations. In my high school in Wilkinsburg, Pennsylvania, I was an exception. It is basically the skeptical part of science, the one where you test one idea against another. Introducing a film at an angle, for example, creates a torque on the film, but if is inserted at the normal to two parallel plate capacitors, no torque (net, anyway). There's a reason why problems solvers are paid more than jobs only involving mundane labor. Just like a mechanic, a student in physics not only needs to know how to wield their tools but also how to use them on a complex problem. Physics is the culmination of learning the endless language of mathematics and combining complicated concepts to solve complex problems. Most colleges … A Level Physics will be harder because assumptions and simplifications are gradually being removed to resemble real-world scenarios. In the question, you are given all the information you need. The learning process is difficult. Relevance. Others struggled, and had to work hard, but eventually figured out the material. 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. Physics 2 is the hardest class ive taken and im a senior mechanical engineering. I'd say sciences in general are difficult because of this. And more importantly: is it justified? Differential equations require knowledge of calculus, which involves algebra and so on. Nature is a harsh mistress, and that's why physics is so difficult. AdamPA1006 Not reallllly. I'm a really good student, but I think I've met my match with physics. Every one of us wonders about how winds blow, how stars twinkle, why desert cold at night and why the sea is salty. But ok. Physics is really hard (at least for the general population of non-geniuses, myself included). Favourite answer. The endless joys of physics-al comedy. Chemistry has a reputation as a hard class and difficult science to master. :D. This is so true, and so well said. Humans think though development of a picture of the minds eye. That's a question we all have different answers for. That takes years of practice. Moreover taking a physics class can seem so far removed from the real world! It seems you just cant 'memorize' things in this class, like you can with any other class. 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. It can certainly get overwhelming- all that math, all those equations. And I've always felt the statement about the worst teachers being those who didn't have to struggle to learn the material, has a lot of truth to it. That was the theme of George Musser ’s keynote talk at a seminar for science communicators held this week at the University of Leeds. Hope you did well on the exam today, I took it as well @fprime: google "feynman djvu". You see the process of starting from the general (e.g. I will re-purpose it! Either way, many students resort to memorizing equations to try to pass the "Motion in Two Dimension" exam. They get surprisingly good reviews. It lends to precise thinking and logic when describing the laws of nature...the physics and chemistry. Edit: Although this seems like a general study question, its actually a very specific question. site design / logo © 2021 Stack Exchange Inc; user contributions licensed under cc by-sa. What is an effective way to evaluate and assess employees on a non-management career track? 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. Pretty hard, right? I really like your descriptions of thickness, depth, breadth, etc. If On our exams, most questions are quantitative. Use the equations to construct some equations that reflect your intuition about what will happen. and true understanding often boils down to an interest and curiosity. Why is physics so hard? Unfortunately it's not clear why despite the learning effort you seem not to perform so well at the exams. If you're good in computer science classes: Here it's the same. Which is why that first quarter physics grade report, bearing an A-, prompted me to cry for an entire hour-long car ride. You have different camps pushing hard for their own interpretation. As it currently stands, this question is not a good fit for our Q&A format. I need drivers for Linux install, on my old laptop, Because my laptop is old, will there be any problem if I install Linux? There are various tools at your disposition to do this: experiment, checking for mathematical/logical coherence of the ideas. 2 thoughts on “ IB Physics is Too Hard ” Andy "SuperFly" Rundquist April 4, 2016 at 04:45. 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". If you like physics and want to learn it, and are willing to work hard, you'll succeed. The reason some people are more successful than others at doing this is experience, they can immediately select the potentially successful ideas from a larger set of ideas, without going through all the steps of the destructive part. Also you should have mentally noted any nonobvious tricks needed to get the math to work out. It's not entirely the students' fault - many other subjects taught in school are very accommodating to rote memorization. Try studying together with other students (from whom you can learn). But why does physics have such an intimidating reputation? But yet, even after all this, its not easy to do, but it should be. To study for the exams, I do a BUNCH of practice problems from previous semester exams that they supply us with.
