  1. hello everyone. I am trying to choose which subjects to have in a HL. I know that I have to take HL physics, that one is sorted and decided. but i am wondering if I should have math HL. the career counselor of my school tells me that I am capable of doing it, but my credits would decrease as it is a really tough subject and that is the important stuff. but I also know that I might need to have the knowledge for what is thought in math HL. i really do not know whether is better to have a 6-7's on math SL or to take it HL and to have 4-5's but I would know more content. help please. i need togive them in 3 days. if it's helpful, these are the subjects I've chosen English SL French SL Economics HL Physics HL Math HL or SL? Chemistry HL (I was told to chose 4 HL to have a back up plan, one will be dropped afterwards) thank you
  2. Hello everyone, I am currently doing 4 HL's but I need to drop one as soon as possible. Right now I am taking Math, Physics, Chem and Econ HL. I want to be an astrophysicist. I know that I need to keep Physics HL, I do not know about Math because even though I am strong at math, the teachers say that it will be very challenging for me and I will not be able to get the score I want, but if I drop to Math SL she said that the course would be kinda too easy for me not letting me develop my skills. I have to choose between Chem and Econ which one to drop. If I were to have Physics, math, and chem HL the teachers say I would pick the "death combo", and I can see why. But they complement the best If I were to pick Physics, econ, and chem HL, would I need more maths but should I be okay with just Math SL for astrophysics? or should it be better if I keep Math HL? The other option would be to have Physics, math, and econ HL, in which math would be the most challenging one for me. I have tried the 4 for a semester, and I am allowed to keep it like that for another semester before yr12 starts, but me and my math teacher would like if I decide as soon as possible, if possible before the second semester of my first year starts. Thank you all for your help! All thoughts are welcomed!
  3. What subject combination at HL and SL are the best to become an astrophysicist, especially if you are looking at a pretty high level university like UoT?
  4. Hi all, I've been looking at the grade boundaries for IB Physics and have noticed their is no distinction between grade boundaries for different options (relativity, astrophysics etc...) in paper three. Does anybody know why this is, considering there are distinctions made between options for Mathematics HL which 'level' the playing field if one option was easier/harder than another. In this vain I'm thinking that it would be advantageous to go for astrophysics as it is by and large considered the easiest topic, however it'd be great to hear from people's past experiences of the options (the SL components preferably since I'm taking SL Phys). The class teacher is fairly stringent in her choice of relativity as an option, which I believe is thought to be more difficult, so would it be feasible to study Astro by myself (I'm on a mid 7 currently so am fairly competent)? Thanks,
  5. Hi, everyone. Later this week I'm going to start the EE and I'm desperately trying to decide what I want to write about. At first, I thought about doing it on Geography or Maths, mainly because my other HL subject, Physics, requires a lot of experimentation that can get dull and tedious. Plus, I didn't feel very passionate about many of the topics that people used for their EE in Physics. Until I realized that since I was a kid I was always fascinated by space - it's, in fact, one of the reasons I chose to do Physics at HL. I decided I might write my EE on this, but thinking about how complicated things get up there, and having spoken to my teacher about it, I realised I might have to dig for ideas to get a suitable, testable topic (I mean who has the means to get into space nowadays? Apart from NASA and other space research groups, of course). One of my initial ideas was working out the ideal time for a space vehicle to leave the earth and travel someplace in space, for example, a planet. This would involve researching into, and possibly calculating the planet's orbits, mapping all the bodies that might get in the way and, using an experiment on earth, work out the gravitational field strength of these bodies to see how much they would affect the vehicle's path, and lastly, working out at what speed and how far from the planet the vehicle would be able to enter orbit. This would also involve experiments in a vacuum, which I can do. How does this sound? Thank you for your time
  6. Hello, I just wanted to seek some help from students or past students on some EE stuff I have been struggling with. I am sorry if this posted in the wrong forum or place, please correct me If I am doing anything wrong. I am doing my EE on physics, and specifically I would love to be able to do something in Astrophysics. I have been reading some exemplar EE's and seem that most experimentally-based essays tend to score higher. Having said this, I would like to do an experimentally-focused EE on Astrophysics. However, problem with this for me is finding a topic and the time I have given. I was looking into some things I could do; such as investigations into skyglow as seen the varying levels of light scattering, or an investigation into eclisping binary stars or determining bary centers of binary star systems. The thing is, topics like these could take months of observation, and I think it would probably be best to limit myself to 1-4 weeks of observation. Are science EE's usually more argumentative? Do I need to argue how something is better than something else for example? Do any of you have experience with this or any advice on topics or how I can develop my topic from this? Any kind of advice is appreciated. Thank you
  7. Hello So right now, I am student in grade XI with my end of year exams in may and my final IB exams next year. Recently we were asked to submit our subject choice for our Extended Essay and I chose physics simply because I have a deep love of the subject and I wish to work in this field later on as well. So I have been quite excited for the Extended Essay and I had a lot of discussions with my physics teacher as well in this regard. I wanted to do my extended essay in Astrophysics, specifically related to calculating the mass of Galaxies, however, this would have been a highly theoretical based topic and hence my teacher was discouraging me from pursuing an EE in astrophysics. I didn't really pay much heed to her since I am really into this subject. Recently though, after reading all the subject criterias, the physics EE subject guide, and also seeing one EE in astrophysics that was there on the internet, I was having my doubts whether it would be the best course of action to do a theoretical based EE in physics. A lot of people have told me that even generally the requirements for a physics EE are quite high and it is difficult to score well, so doing a theoretical one, which would have only minimal experimental backing would lose even more marks. I'm confused as to what I should do, since studying astrophysics has been my dream since a very young age and I really wanted to do my EE in it, but all other factors seem to hint that I shouldn't do it. Any and all help would be highly appreciated. Thanks in advance Prajit Baruah India Grade XI
  8. I am wondering, where, when and how do we apply astrophysics in real life?
  9. Hi IBSurvivors, IBWarriors, IBAlumni, IBTeachers and Future IBWarriors :$ Can someone recommend excellent/classic must-read books for an astrophysicist? All suggestions are welcome, from textbooks on the subject to best-sellers written by authors such as Carl Sagan, Neil DeGrasse Tyson etc. I just want a bucket list of stuff to read in my 3 month break. Also, please suggest some TV shows/movies on anything close to the subject!! I particularly like Cosmos: A spacetime odyssey (hosted by Neil DeGrasse Tyson). Star Trek/Wars are of course the classics. Thaaanks !!!!

    Here is my detailed IB physics HL notes that I took during my IB years. This part contains notes for 2 HL options (Astrophysics & Relativity). Hope it is useful for those taking physics
  11. "Does Kepler's third law apply to objects with highly irregular orbits, such as comets?" I have access to an observatory, so I can actually do an experiment with it, and none of my physics textbooks are willing to say whether or not a comet will follow Kepler's Third Law. It will follow the first two. I suppose I could focus on a specific comet, since ISON is up right now (and observable) and I know somebody with a physical database of some very old observing data. However, my supervisor, while great in pointing out resources, doesn't know much about the EE... Feedback?
  12. Hello everyone, I'd like to do an extended essay for astrophysics, and after some time I narrowed down my topic to the stars. My idea is to determine the age of the milky way using hubble's constant. Or, I suppose the age of the universe would also work, as that would be going all the way to the big bang. My problem is that I have seen one Yahoo! Answer that basically answers the age of the universe in about a paragraph, and although I would like to do a data-based essay and figure out Hubble's constant myself, I don't know whether or not it is far too simple or not. We will do Astrophysics as our option in our physics class, and so I don't know whether or not this will be in the syllabus and so too easy for it. tl;dr I would like to do my EE on the age of the universe by determining Hubble's constant, is it too little for an extended essay? I am in Physics HL and will do Astrophysics as an option. I don't want to ask my supervisor as I want to first get a feasible topic (we already went through about 5 topics and discarded them, so I want to finally get a proper one when I meet her this time) so I am hoping you guys could help me.
  13. I am in IB1 but in the summer i shall have to make the choice of where i want to go and what i want to study. Up till now i have always wanted to study marketing, but that was something i was just good at, liked and is what my teachers told me that i should do. Now i have an interest in Astronomy and it is something i always just enjoyed reading about or learning about. This is why i thought of doing astrophysics, now we get to the complicated part, i did not take physics ever before in my life so that would mean i would have to do an foundation year physics, also my maths is not good enough to enter any physics course leading me to an foundation year of maths. Now my problem is i would love to understand the criminal mind and solve crimes, its something i always found truly interesting this is why i am considering doing Criminology with Criminal Justice and Law. I dont know which one would be best considering i take the following subjects: English HL, Dutch B HL, Geography HL, Math studies SL, Biology SL, Business & Management SL (these were all choices made due to the fact my school does not give a wide range of subject choices). I would really like to hear some of your opinions since i am truly lost. What do you think is the most interesting to do? Why should i do it and why should i not? And which universities are the best in the United Kingdom for it? (max my teachers think i can get is 32-36 points for entry) And what is the difference between an Criminology with Criminal Justice and Law degree and an Criminology and Law degree?
