I wanted to make a video showing what classes you must take in order to get a Bachelors Degree in Physics. I also give a brief description of those classes.
So true. What got me interested was not the quantum/nuclear physics and astrophysics stuff either. it was the classical physics and electric/ electronic stuff🤭
remember one thing. math is used to supplement physics, not supplant it. no excuse is allowable for any teacher to throw a bunch of equations, formulas, proofs, etc., without a proper explanation of the underlying concepts that buttress the math. if you need to, meet with your classmates, and if they don't want to, then do it your self, understand fully well all physics concepts. and go no further in your study until you know what the term 'all physics happens at the margin' means. i had profs say this time and again without ever attempting to explain what that meant. it was only when i heard it for the 100th time that i stopped a class and said that it was time for them to either explain what it meant, or admit they didn't know what the hell they were talking about.....
How would you explain the meaning of “all physics happens at the margin”? I am really interested. It sounds like the way you solve physics problems. When ever you have to find a physically acceptable solution you will often solve for the boundary conditions? My lecturers have never said anything like that but then again I do not live in an English speaking country
I went into physics because I liked math and how it all fit together. Also out of curiosity about everyday silly little things, such as wondering at age 6 why my thumb and index finger appeared to merge together when I brought them close enough, in front of a bright background. I must have been a puzzle to my parents. I teach intro physics and I try to make it as easy as possible, not as hard as possible. And I think that reflects what most physics professors strive for. The reason intro physics is so hard for students is that there is indeed a lot of material, but mainly because it is often their first introduction to a whole new way of looking at the world. It's like learning a new language and also an entirely new culture. All in the span of 2 semesters. We make it as easy as possible, but the rest is in the end of the motivated student. It is normal to have to spend a lot of time practicing before it starts making sense. Once one gets over that hurdle, many of the classes that follow get easier, even though they cover more advanced material. But yes, we want our engineers to have a solid understanding of physics, because we don't want them to build bridges that crumble. And a solid of understanding of physics can only come with a lot of hard work.

@@Off_the_clock_astrophysicist thank you very much. I've actually studied diffraction and the double slit experiment by thomas young but i didn't know that diffraction causes that phenomena. thanks again. have a nice day!
Matthew Zárate good news is, first year was probably the hardest for me. They make university physics unnecessarily difficult to insure they're not creating engineers that don't understand physics and let their bridges collapse.
Andrew Dotson Thank God haha. It's crazy seeing how full of students each lecture is at the beginning of the course, and at the end, so many have dropped. I enjoy your videos!
Seems like a Physics degree needs a lot of discipline. Not sure if I can have that much discipline for 3 years. I might get frustrated after a while. Sound bad I know. I want to do it but I am afraid that I might get frustrated.
RoyalDomi You're talking to a guy that got average grades in high school, got a D in freshman level college English, but managed to turn it around and get straight A's last semester in 400 level math and physics. For me, the discipline came once I realized I couldn't have the life I wanted unless I got my priorities straight and learned to try my best consistently
I'm currently in grade 10 and have been really passionate about physics all my life. It's the subject I know I'm going to go into. Other than just somewhat aimlessly learning theories and reading textbooks, it's great to know what I'm in for in university in such a concrete form. I really appreciate it!

To go into physics you need to have natural inclinations to think intuitively. I think physicists are in many ways discovered. In HS I took physics and it was one of the easiest classes. Everyone else had difficulties. I went on to get a graduate degree. Still love it 25 years later.

Andrew your videos are so inspiring. I want to know more about how things work in this world and I’m slowly starting my physics journey later in life. It won’t be easy but I know it will give me all the answers I’m always asking. Hopefully I can be at your level one day
It is nice to hear the intro classes are known for being difficult. I've felt fine so far in Gen Physics 2. We just hit magnetic induction and faraday's law, and it just turned up a notch...
Oh man I remember taking classical mechanics, what a ride that was. CAlculus of variations leading to Euler and Lagrange equations, woo, that class was brutal but lovely.
Cool video, I just finished my first year college and wanting to be a dentist; but I'm not to sure in what major yet (most likely going to be biology) anyways I'm watching tons of math and physics videos over this summer to be prepared when I take physics and other challenging classes I need; your video helps by the way on what to expect and I bought math and physics books to read from Amazon. 😊
I remember reading through the Course Catalog as a Freshman and coming across stuff like: Lagrangian and Hamiltonian Dynamics, the Schrödinger Equation, Quantum Statistics, etc. and wondering what I got myself into! Don't let it freak you out.
Excellent video. I’m a second year engineering major. Did all the calculus and differential equations and physics 1,2,3. Trying to decide if I want to switch to physics. This helped a lot.
Econophysics dear, Econophysics. Look up that subject. Seeing the following equation helped me realize that Newton's Law of Universal Gravitation was truly universal as in it applies to studies not normally associated with Physics. This is a formula that I read in a graduate level Economics course book at 3AM in a dorm. It was introduced to me by a Economics Graduate Student .Knowing that I was studying Physics he asked me, 'Does this equation look familiar to you?" Fₘ = k(Wₚ - Wₒ)(MₒMₚ)/[(Sₚ - Sₒ)]² where Fₘ is the force of migration, k is an arbitrary constant, Wₒ is the prevailing wage in City Sₒ. Wₚ is the prevailing wage in City Sₚ, Mₒ is the population of City Sₒ, Mₚ is the population of City Sₚ, and. the quantity (Sₚ - Sₒ) is the distance between the cities Sₒ and Sₚ The equation describes the fact that the migratory force between two cities is directly proportional to the product of the difference of the prevailing wages in the two cities and the product of the population of the two cities, and inversely proportional to the square of the distance that separates the two cities. It was an epiphany. It is basically no different than F₉ = G m₁m₂/{(r₂ - r₁)]² which is Newton's Universal Law of Gravitation. Enjoy your exploration.
Thanks for this video, I had recently discovered I wanted to go into astronomy, and I've heard physics would be a good major. Good information. I hope I have the discipline to follow through
Ooh boy, I took classical mechanics at the same time as calculus 3, and that was definitely confusing for a long time, but by the middle of it, we were talking about topics in calculus that I basically just assume was true at the beginning of classical. It was definitely an interesting way to learn it, and it definitely made calculus more of an investment when I saw a proof and thought, ‘Oooooh, that’s the professor meant when she said this thing three weeks ago.’
@@sethnesmith6091 Great! I'm in my senior year - still a physics major! And got selected by the Air Force to go to pilot training after I graduate! I think that was partly because of my STEM degree
@@SilentJBeast that’s awesome! That’s funny cause I just got out of the army and now I’m gonna be heading into physics.

I totally agree with you dude about perspective of physics as a subject and teachers who teach it. I think it's because of these people that we start hating some subject.
I was having doubts if i should take physics being afraid of not being able to find a job but i see how you answered some peoples questions and i have my mind set thank you very much
It's really interesting seeing when things are studied in the American system compared to the UK where I currently study. In the UK we only do straight subjects so I only take physics and relavent maths modules and don't have to do anything from other courses. Most of the things which you mention in the second year is covered in our first year, and the course is overall shorter compared to going to university in the US.
In the us, our college curriculum covers some things we might’ve took in high school which may increase the degree program to 4 years instead of 3 years like how a lot of the world does
You're going to be fine, dude. Even though I'm a high school senior and my words have less merit than suppose an actual college student, I've heard numerous anecdotes about the materials looking intimidating at first glance, yet it wasn't as bad as they initially thought. Me, browsing Andrew's videos, I feel especially scared because I don't understand more than half of the things he's saying. But when I was about 8, and when I first saw the integral symbol, or dy/dx, or polars from my older brother's homework assignments, I didn't know a single thing. Of course, settling in Calculus BC (Calc. 2), I'm finally learning the things I initially thought I was never going to understand. All it takes is starting from the ground up and going from there, rather than leaping on numerous topics.
Ty man. I finished high school a couple months ago and am 3 months away from starting my freshmen year in physics. Although I live and will study in Croatia i don't think it is too different from what you talked about so all this is info is pretty helpful. Also I am kind of scared because I don't know if I will have the chops for all of it since it seems pretty difficult on first glance, but I think all I can do at this point is just try and find out.
To me, as a physics major in my senior year, I feel like intro physics is difficult because the formulas are motivated and derived by a deep understanding of not just the world but also mathematics like multivariable calculus. The students are expected to use these formulas as though they have a fundamental understanding of them in order to solve problems, but they can never have a fundamental understanding because it is their first year. That's how I look at it anyway.
I wish you could have taken my introductory physics course. You'd get to see it doesn't have to be as hard as professors make it and still get everything you need out of it. I was one of those first type students, more interested in the Newtonian stuff than the fancy black hole, special relativity stuff.
Wow thanks for that video. Im thinking about studing physics but i keep hearing that its hard and that only 10 people out of 120 make it to the end of the degree in my country. Today ive heard ill probably just give up and swich to economy after a while. Your video lifted my spirit up a little tho. Thanks for explaining what it really is. Im less stressed id be murdered on spot by all that difficulty haha.
I like physics as it helps apply mathematics to real life, going in to develop different computer power design. Computational physics is were I am excited to go into now, only a freshman now though I will be taking physics next fall. Your videos are really helpful thank you.
i wish i could've been good at math.. physics looks so interestin.. more than biology and chemistry :( well i like bio and chem but i think physics looks awesome
If you're good a math you won't be good at physics, you just need to understand math. It's a different kind of thinking entirely, math is just a way to quantify what you're talking about.
No matter what people say to feel superior, high level chemistry requires a lot of math too, not as much as physic but a lot none the less. I have a friend who is currently doing his Dr in physical chemistry and he took all the math courses you take as a physicist (in bachelor an master) in addition to all the other stuff because the mandatory math courses for chemistry are just not nearly enough.
love this video!! im about to graduate from secondary school and am going into a biomedical engineering course in a polytechnic but i really want to study physics in university
To any potential first year about to delve into physics , heed this gentleman's words , introductory physics can be deceivingly hard , like , getting a 20% in a test for the first time hard , and the math , make sure your math game is on point.
@@rcksnxc361 In my experience it was ,i guess it depends on ones' math and physics background (which i assume is very strong ) and also on ones' problem solving skills too( a department most are mislead into believing we are good enough in ).
One video cleared all my queries, thanks very much!! I have just one question, did you find it difficult to adjust with your peer group, because many of them come from very competitive background, if yes, how did you overcome this problem?? Thanks
I'm in my first year of college, i have never taken a single physics or calculus class in my life and I'm majoring in a social science(but honestly I don't know what to pursue in my major) but lately I been having an interest in physics and I want to give it try but I fear that i'll just regret it and end up on the same boat i'm already on in my major
Engineering is just natural sciences applied to method, in my opinion. Engineers, mathematicians, physicists, they study and work similar topics but slightly different applications, so you can get your bachelor's degree in engineering and then move to fields of research in physics later I want to get into mechatronics and study robotics and AI. I already have background in programming and basic computer science, so when I get into university I plan to either get into electrical engineering, mechanical engineering or computer science itself
@@tempestandacomputer6951 This is the problem right here. Everyone expects that other people will do your work for you. It is not hard to figure out career options for certain majors. Do somecresearch and be proactive.
An error when sb starts a degree/major, class is class u can do what u want and research what u curious in, so you dont need only to follow the lectures and your notes about them but u can search deeply 4 u own and find a passion, yep, college/major is a "ticket" but u knowledge is got by u love not by u marks... (you always gonna find time to those things are attracting to u) This is a small tip/ point of view ps: sb to correct me? Im not native so i rly appreciate it! btw Nice vid Andrew!
Thank u for this explanation... For me i study physics but it wasn't like this.... Instead of studying those basics u mentioned we studied chemistry and simple math +some of newtonien physics in the first two semesters.. After it they made us jump directly into electromagnetic and quantum mechanics.... Now I understand why I'm still fighting to understand what the hell is this lol!.... There is a lot of things and basics missing.
Hey man, I just wanted to say awesome vid and thank you for making it. I'm currently a freshman in college and I didn't do well in high school and i'm scared I'm not smart enough to get through this major. I wanted to know if you have any advice for someone who had a D average in high school and never even took calculus.
Hey this is an amazing video but it sounded like you were whispering. Not sure if it’s because of the room echoing but maybe add a little more tone :) love the video so useful
"This also gonna be one of the first classes since you introductory physics days that you'll be using real numbers again" I don't think that Al-khawarizmi thought that Algebra will make a such weird language and this language will be spoken in different dialects
I’ve taken Ap physics (In my junior year of high school ) I really enjoy everything physics has to offer. I’ve decided I want to be a physics major and want to know where to start. I’m still a junior but I used past tense to show that the school year is almost over( 4 weeks till summer)
Love physics because I am so intrigued by how the world works but for some reason I really hate math. Idk unapplied math is just a headache but when we associate it with objects, and trajectories and etc it gets interesting
Crazy that what they have in USA in third year (Electrodynamics and statistical mechanics) we have here in europe in second semester. Also it’s weird that you have special relativity towards the end of electrodynamics, we had it in the begining and basically derived magnetostatics from it (things like Lorentz force, which I’ve seen in Grifiths is just 'given'.)
I’m really interested in astrophysics as a high schooler! Are there any books you recommend for someone who doesn’t know much? I was thinking of Stephen Hawking literature.
I’ve been really into physics lately, I did my undergrad in Computer Science though, but with a little bit of post bac work does a masters in physics sound like a good way forward?
Hey, I'm a first year and I watched a few of your videos and loved them. I am very passionate about physics but I love computer science too. I thought about doing the combined major but that would make it so, that, I wouldn't go too in depth with physics or maths. Everyone keeps on telling me that it will keep on getting harder and I'll stop liking it but I took the honors level physics this year and I loved it. I think I do want to learn physics more in depth. However, people also say compsci is an easier way out and software developers earn a lot more money, but I don't know if that interests me. Any advice would be great.
Have you taken any programming courses? Physics definitely gets harder, but it also gets more real. You start learning how describe actual things instead of spherical cows with no friction. It's really hard to say, because I don't know your situation, but I have the good fortune of being able to pursue what I'm passionate about instead of the money route. Truthfully, I'm not so sure compsci is any easier.
Andrew Dotson thanks for taking the time to reply. I've taken a few compsci courses, and they seem to be easier than the physics courses. However I do seem to enjoy physics more.
thats pretty much all there is, huh? i really want to be a physics major but i guess i did not really understand how much work there would actualy be to it. this seems like madness and im probably gonna die under the workload in the first few months

Esteban Canizales That's so great to hear! If you have any questions, feel free to ask and I'll try my best to help!
Very insightful, thank you
Thank you so much
This video was simply amazing
Informative and well presented
It's really interesting seeing when things are studied in the American system compared to the UK where I currently study. In the UK we only do straight subjects so I only take physics and relavent maths modules and don't have to do anything from other courses. Most of the things which you mention in the second year is covered in our first year, and the course is overall shorter compared to going to university in the US.
In the us, our college curriculum covers some things we might’ve took in high school which may increase the degree program to 4 years instead of 3 years like how a lot of the world does
Always wanted to know abt this. Thanks man
I'm questionning my ability to study physics, eventhough I really wanna do it
You're going to be fine, dude. Even though I'm a high school senior and my words have less merit than suppose an actual college student, I've heard numerous anecdotes about the materials looking intimidating at first glance, yet it wasn't as bad as they initially thought. Me, browsing Andrew's videos, I feel especially scared because I don't understand more than half of the things he's saying. But when I was about 8, and when I first saw the integral symbol, or dy/dx, or polars from my older brother's homework assignments, I didn't know a single thing. Of course, settling in Calculus BC (Calc. 2), I'm finally learning the things I initially thought I was never going to understand. All it takes is starting from the ground up and going from there, rather than leaping on numerous topics.
Thank you. This is short, and useful.
Thanks for the information Andrew 👍👍👍👍
great explanation, best I found here!
Ty man. I finished high school a couple months ago and am 3 months away from starting my freshmen year in physics. Although I live and will study in Croatia i don't think it is too different from what you talked about so all this is info is pretty helpful. Also I am kind of scared because I don't know if I will have the chops for all of it since it seems pretty difficult on first glance, but I think all I can do at this point is just try and find out.
You.
Can.
Do.
It.
Effort brings success and happiness :)
To me, as a physics major in my senior year, I feel like intro physics is difficult because the formulas are motivated and derived by a deep understanding of not just the world but also mathematics like multivariable calculus. The students are expected to use these formulas as though they have a fundamental understanding of them in order to solve problems, but they can never have a fundamental understanding because it is their first year. That's how I look at it anyway.
Thank you Andrew this was awesome.
CosmicScattering really happy you enjoyed!
Thanks for bringing me back the goodal days
I wish you could have taken my introductory physics course. You'd get to see it doesn't have to be as hard as professors make it and still get everything you need out of it. I was one of those first type students, more interested in the Newtonian stuff than the fancy black hole, special relativity stuff.
Wow thanks for that video. Im thinking about studing physics but i keep hearing that its hard and that only 10 people out of 120 make it to the end of the degree in my country. Today ive heard ill probably just give up and swich to economy after a while. Your video lifted my spirit up a little tho. Thanks for explaining what it really is. Im less stressed id be murdered on spot by all that difficulty haha.
I like physics as it helps apply mathematics to real life, going in to develop different computer power design.
Computational physics is were I am excited to go into now, only a freshman now though I will be taking physics next fall. Your videos are really helpful thank you.
Best of luck !
i wish i could've been good at math.. physics looks so interestin.. more than biology and chemistry :( well i like bio and chem but i think physics looks awesome
Hey me too im not that good in ohysics although iam kinda good in maths
Chemistry is an extremely mathematical subject tho?? Not sure about bio.
If you're good a math you won't be good at physics, you just need to understand math. It's a different kind of thinking entirely, math is just a way to quantify what you're talking about.
@@themultigamer5682 I learnt that the hard way recently. I realised one needs to truly understand.
No matter what people say to feel superior, high level chemistry requires a lot of math too, not as much as physic but a lot none the less. I have a friend who is currently doing his Dr in physical chemistry and he took all the math courses you take as a physicist (in bachelor an master) in addition to all the other stuff because the mandatory math courses for chemistry are just not nearly enough.
Watching this video, everything seems so daunting.
I’ve always loved physics, but I know I don’t have it in me to succeed as a physics major. Good luck to everyone pursuing this field!
You seem like a good dude. Keep that up
love this video!! im about to graduate from secondary school and am going into a biomedical engineering course in a polytechnic but i really want to study physics in university
really appreciate your videos keep going!
Robin M thank you so much! Will do!
To any potential first year about to delve into physics , heed this gentleman's words , introductory physics can be deceivingly hard , like , getting a 20% in a test for the first time hard , and the math , make sure your math game is on point.
I want to study meteorology/ geoscience(can't decide🤔) but I'm fucking scared that I can't handle the physics and math homework :/
Sam Fisher that bad? ._.
@@rcksnxc361 In my experience it was ,i guess it depends on ones' math and physics background (which i assume is very strong ) and also on ones' problem solving skills too( a department most are mislead into believing we are good enough in ).
Holy nuts! I did not realize how many classes I'd need to take
My mom's a physics prof and u honestly remind me of her
Haha. Love your videos my guy. Next year I am going into my 3rd year of Physics.
Well covered, thank you
Loved Your explanation
You have a calming voice
Love your videos!
Savannah Bertrand thanks so much!
Your going to be the next Carl Sagan ☄️🔭 I just subscribed 😁
Jose Leonardo Monier IV That's a pretty big compliment! I appreciate the sub✊🏼
Hahahahhahaa if only these people saw andrews videos today
One video cleared all my queries, thanks very much!!
I have just one question, did you find it difficult to adjust with your peer group, because many of them come from very competitive background, if yes, how did you overcome this problem?? Thanks
I'm in my first year of college, i have never taken a single physics or calculus class in my life and I'm majoring in a social science(but honestly I don't know what to pursue in my major) but lately I been having an interest in physics and I want to give it try but I fear that i'll just regret it and end up on the same boat i'm already on in my major
I like how andrew's voice in this video sounds like him doing a first year impression in the later videos.
Sounds fun, can't wait
excellent video.. Tempting me to switch from engineering to physics,but I think i'll pass.
Dang it, so close! Come to the Dark Side. We have cookies
Im on the same boat... gosh I wish high school sometimes provided more opportunities as to experiment with your career interests more.
Engineering is just natural sciences applied to method, in my opinion. Engineers, mathematicians, physicists, they study and work similar topics but slightly different applications, so you can get your bachelor's degree in engineering and then move to fields of research in physics later
I want to get into mechatronics and study robotics and AI. I already have background in programming and basic computer science, so when I get into university I plan to either get into electrical engineering, mechanical engineering or computer science itself
@@tempestandacomputer6951 This is the problem right here. Everyone expects that other people will do your work for you. It is not hard to figure out career options for certain majors. Do somecresearch and be proactive.
@@tempestandacomputer6951 yeh...dude
Thank you sir for the awesome video you made. Both intelligent and handsome keep up the good work.
Thanks so much!
What we're your maths and physics grades in high school?
An error when sb starts a degree/major, class is class u can do what u want and research what u curious in, so you dont need only to follow the lectures and your notes about them but u can search deeply 4 u own and find a passion, yep, college/major is a "ticket" but u knowledge is got by u love not by u marks... (you always gonna find time to those things are attracting to u)
This is a small tip/ point of view
ps: sb to correct me? Im not native so i rly appreciate it!
btw Nice vid Andrew!
Thank u for this explanation... For me i study physics but it wasn't like this.... Instead of studying those basics u mentioned we studied chemistry and simple math +some of newtonien physics in the first two semesters.. After it they made us jump directly into electromagnetic and quantum mechanics....
Now I understand why I'm still fighting to understand what the hell is this lol!.... There is a lot of things and basics missing.
This is actually a really good video
Glad you like it!
Awesome video!
Thank you for your video.
I am actually fascinated by projectile motion 😊
For some reason this is the only video in which the dude looks...insanely attractive.
Ik what u mean lol
Hey man, I just wanted to say awesome vid and thank you for making it. I'm currently a freshman in college and I didn't do well in high school and i'm scared I'm not smart enough to get through this major. I wanted to know if you have any advice for someone who had a D average in high school and never even took calculus.
How’s it going three years later? Hopefully it all worked out for you, Im currently also getting through my physics degree
Hey this is an amazing video but it sounded like you were whispering. Not sure if it’s because of the room echoing but maybe add a little more tone :) love the video so useful
"This also gonna be one of the first classes since you introductory physics days that you'll be using real numbers again"
I don't think that Al-khawarizmi thought that Algebra will make a such weird language and this language will be spoken in different dialects
That Schrodinger's equation is also wonderful
I never got accepted into summer research unfortunately, but i did get into research with my professor.
Love how casual he is at the end
“That’s pretty much all there is too it just some differential calculus and string theory” 😂
I’ve taken Ap physics (In my junior year of high school ) I really enjoy everything physics has to offer. I’ve decided I want to be a physics major and want to know where to start.
I’m still a junior but I used past tense to show that the school year is almost over( 4 weeks till summer)
Life update?
hows it going?
update?
Love physics because I am so intrigued by how the world works but for some reason I really hate math. Idk unapplied math is just a headache but when we associate it with objects, and trajectories and etc it gets interesting
Same
Crazy that what they have in USA in third year (Electrodynamics and statistical mechanics) we have here in europe in second semester. Also it’s weird that you have special relativity towards the end of electrodynamics, we had it in the begining and basically derived magnetostatics from it (things like Lorentz force, which I’ve seen in Grifiths is just 'given'.)
I’m really interested in astrophysics as a high schooler! Are there any books you recommend for someone who doesn’t know much? I was thinking of Stephen Hawking literature.
Sophomore physics undergrad heading into electromagnetics! Great vid!
While most of these classes sound difficult, I'm actually veryyy excited to start tackling these problems
it’s been 4 years now, how was it ?!
The amount of change in 3 years damn
yo whadup young Ben Affleck with a physics major
if you get an F on a report, mention F=ma, and if m were to equal 1, therefore F=a, therefore, you have an A
I’ve been really into physics lately, I did my undergrad in Computer Science though, but with a little bit of post bac work does a masters in physics sound like a good way forward?
Hey, I'm a first year and I watched a few of your videos and loved them. I am very passionate about physics but I love computer science too. I thought about doing the combined major but that would make it so, that, I wouldn't go too in depth with physics or maths. Everyone keeps on telling me that it will keep on getting harder and I'll stop liking it but I took the honors level physics this year and I loved it. I think I do want to learn physics more in depth. However, people also say compsci is an easier way out and software developers earn a lot more money, but I don't know if that interests me. Any advice would be great.
Have you taken any programming courses? Physics definitely gets harder, but it also gets more real. You start learning how describe actual things instead of spherical cows with no friction. It's really hard to say, because I don't know your situation, but I have the good fortune of being able to pursue what I'm passionate about instead of the money route. Truthfully, I'm not so sure compsci is any easier.
Andrew Dotson thanks for taking the time to reply.
I've taken a few compsci courses, and they seem to be easier than the physics courses. However I do seem to enjoy physics more.
He cute
You gay.
1:05 A ton of people get into physics to talk about lasers, optics, semiconductors, etc... However, the reasons you listed are why I study physics.
thats pretty much all there is, huh? i really want to be a physics major but i guess i did not really understand how much work there would actualy be to it. this seems like madness and im probably gonna die under the workload in the first few months
Mfw they make me take math methods before linear algebra and ODE and then I wind up taking waves this semester without taking ODE, kill me please.
dude I did electrodynamics in two weeks in my first-year bachelor's. It was honestly not that hard, and it was super interesting!
