I'm looking for a book to self-study this summer before my last course of Bachillerato (A Levels or High School in other countries). My performance in Mathematics has only improved and I've just been given the maximum mark this last term (10/10 or A+). This has motivated me a lot to keep...

Hi all, I am currently a second year physics student who has started thinking about his third year project, I am hoping to do teaching upon completion of my degree and have been advised to link my final year long project to teaching in some way. The issue I am having isn't thinking of a...

Are there any good first year textbooks which cover first year differential (limits, partial derivatives, intro vector calculus), integral calculus, DEs, AND linear algebra - vectors and matrices. other stuff like complex numbers, infinite series, etc would be a bonus. As in a single textbook...

See the picture below for details. I have included my solution thus far, but it doesn't feel right and I'm just wondering what I am missing. Any assistance would be greatly appreciated, cheers.

sup guys im currently year 2 studying electrical & electronic engineering. Next year we had to choose modules where it was split equally between magnetics(mainly covered with waves, optoelectronıcs, nano technology and like magnetic materials etc), power(renewable, machine power, a bit of...

my son is trying to find out how he can find an answer by being shown how to do the working out he wants to find out what the wavelength is if he only has the hz if he is 93.4 hz how does he find out what the wave lenth is thanks

I am a second year physics undergrad at UCSB with a decent gpa (3.65). I am wondering if anyone here has any suggestions of things I should get involved with to improve my resume for future research/internships. As of now I do not have much of anything to put on a resume, besides non-physics...

Hey Everybody, So I made it into Waterloo's honors physics program, which has been a goal and dream of mine for years. It feels great but at the same time, I really want to know how to prepare for the program before the fall and get ahead. I taught myself the essentials of differential...

Chinese Lunar New Year confusion (BBC News) Here's what one goat thinks of the matter:

So my situation is a little odd. The first part is that I'm double-majoring in physics and electrical engineering. Currently, I'm a "junior", in that I'm in my third year and have junior standing. However, there is a bit of weirdness. Because of all of the requirements of my major, I'm going...

As stated in the title I'm wondering if I'd be able to pursue a career in Physics at the age of 16. I'm only asking because it seems like many physicists had taken up a serious interest in science at a young age. Obviously I've taken science related courses throughout my life time but I feel...

I didn't know where to post this, but, this video makes my eyes water.

Homework Statement If a stock has increased 400% over the last 6 years, then how much does it grow on average per year. Homework Equations 400 = 100(1+r/6)^6 The Attempt at a Solution Divide both sides by 100 4 = (1+(r/6)^6 Take the sixth root of each side. 1.26 = 1 + (r/6) Subtract...

Hi guys, So in my current situation it is pretty rare to come across people who are mathsy/physicsy, which is why I'm venting here for the advice of some like-minded people. I took a gap year pre-university to work, travel and generally get my head straight but am starting to worry about the...

Homework Statement A year has 53 Sundays. What is the conditional probability that it is a leap year. Homework Equations None that I can think of. The Attempt at a Solution I tried by knowing that a leap year has 366 days. Next we can note that the remaining 2 days could be sunday and monday...

I'm a Physics major and am starting on my early major courses (Classical Mechanics and E&M, and an Abstract Algebra course as an elective). I've already taken an upper div Linear Algebra course and a Math Methods course (though the latter, which covered topics in Linear Algebra, Fourier...

i'm not sure if this is the best place to post this so if its in the wrong place I'm sorry and ill try to move iti've always loved physics. I've never been good at much of anything except math and science. Never could play an instrument worth a damn, zero athletic ability, and so forth, but math...

I am doing Electrical and Electronics engineering. I am current in my 6th sem (8 in total). From the 7th sem i would have to choose a topic/project for my final year, which will go on till the end of the course. I want to pursue physics as my graduate studies. I have been trying to think of...

I'm starting a physics major this year and I'm currently enrolled in foundation physics (algebra, vector based). However, during second semester I'll be doing doing a regular physics unit which is based around technology. The main topics are Electromagnetism (LOTS and LOTS of circuits work...

hi gang, been pretty quiet couple of months with no significant events for December and up till yesterday for Jan M6.8 - 84km NNE of Port-Vila, Vanuatu 2015-01-23 03:47:27 (UTC) 17.000°S 168.531°E depth=218.5 km http://earthquake.usgs.gov/earthquakes/eventpage/usc000tihy#general_summary...

Have a personal question for those familiar with the field. I am an "older than usual" undergrad student who is very interested in physics. At 27 years old I have fallen in love with understanding the world through physics and mathematics. I will be declaring myself a physics major this...

Homework Statement Damping is negligible for a 0.164 kg mass hanging from a light 6.70 N/m spring. The system is driven by a force oscillating with an amplitude of 1.77 N. At what frequency will the force make the mass vibrate with an amplitude of 0.500 m? There are two possible solutions...

Hello, I'm currently in college and getting a bachelors degree in physics and engineering, I also might get a bachelors in math too. I was wondering how much money I would start off getting with those degrees together? I've seen how much engineers get and physicist but what if you have both? Thanks

If I had a light year long stick that was incredibly strong, made of diamond for example and held it out at arms length, when I let go of the stick, the end closest to me would start to fall to the ground but 2million+ miles down the stick would still be completely level right? Because those...

Homework Statement Homework Equations W = e*epsilon*z The Attempt at a Solution No idea where to start with this and the hints really aren't helpful All I really know about the Stark effect is that the potential energy of an electron in the field of strength epsilon would be W =...

Seriously, a 5 year old asked me whether entanglement information survives/escapes a black hole. Specifically, he asked me (in only slight paraphrase) whether if one of the particles (headed in different directions) fall into black holes on either end, does the other one know it?

Hi I'm about to start my 3rd year in my Engineering university and would like some ideas for my Final Year project... We have 2 options. We can either make a model/prototype of something and present it OR we can do a research on a particular field. I'm leaning more towards the research side...
