    Worst Fear in an Exam

    I know someone who did it... Luckily for him, it was an optional retake.

    I still remember that question. =D So what was the graph supposed to be like? I don't remember the question, I just remember what I sketched for the graph which I think is wrong... I think the graph I did was wrong too... I did an absolute cosine curve. Something like this. I did the same thing, and yes, it was wrong...

    IB + regular?

    Well, in that case I was talking about me. I find some of the extra subjects we take really hard, so I waste a lot of time studying them, and I think that using this time to study or work on the IB subjects would have helped me to get an IB grade similar to the regular studies' one. Obviously, other people wouldn't be able to get the same grade. Nonetheless, I think that my grades are good enough, so the main difference would be that I wouldn't have taken the extra subjects which I don't like as much as the IB subjects.

    IB + regular?

    Here everyone has to take the normal studies, which we call "bachillerato" (baccalaureate). We take 3 more subjects and sometimes we have to learn different things for the same subject, because of the two programs. They force us to do it this way because they say it's easier to get higher grades, but actually they don't know what would happen if we took just IB. I think that if I had taken only IB, I could have get higher grades which will be equivalent to the grades I'm getting in the normal program.
  6. About the bilingualism and language thing... I speak Catalan and Spanish without any difficulties, but I still don't speak English very well. I live in Catalonia, and here the main language is Catalan. Since Catalonia is politically part of Spain, we have to learn Spanish too. Unfortunately, people are more concerned about learning Catalan and Spanish, so they don't really care about the English level we have. And now that I'm finishing IB, I'll have to stay in Spain because I don't speak English good enough to study somewhere else. Actually, I never really thought about how important English was, but my parents didn't do so, probably because of this general concern about Catalan and Spanish. If I have kids in the future, I think I'll offer them the chance to learn what I haven't learn...

    Paper 1 was easier than I thought it would be... I finished it in 45 minutes and I expect something near 35 correct answers. I did B1 and B4 in Paper 2. And I didn't fill 2 questions (3 points) in Section A. Although probably I made a lot of mistakes.

    What time do you go to bed on average day?

    Yeah, sometimes I go to bed at 5am... I wake up at 7am, so these days are horribly awful. Usually I go to bed between 12pm and 3am.
  9. For me, Physics HL is as difficult as Chemistry SL, so I think that it would be harder to take Physics SL and Chemistry HL because of the Chemistry level.

    Genius vs. Hard Work

    I'm not a genius, but I'm in this reduced group of people who can get high scores on math exams without reading the book. Actually I can do it with all the science subjects I'm taking (more or less). And I have to say that IB isn't easier for me than for anyone else, because before IB I never did homework. Before IB, the only things I had to do were going to class and doing exams. Of course, my final grades weren't as good as my exams' grades, because of homework, but they were good enough. Now, in IB, I cannot choose to don't do homework, and I'm working very hard to complete homework because it takes me like twice the time for a normal person. So, after all, being good at maths and science subjects is not making things easier for me. But it's true that if I weren't good at them, I wouldn't be getting acceptable grades in IB.
  11. I did it. It was kind of easy, using trigonometry and similarities. The most "difficult" question is the second one, because you have to use other methods (actually, the method used for this question is also working for the first one, but it's difficult to find it). The last question is not very difficult if you have done the other questions.

    Further Mathematics Book

    I think that it will continue until 2010. Am I wrong?

    Difficult relativity question

    According to the special principle of relativity, physics laws are the same for inertial reference frames. If there is a force, there is an acceleration, so the proton and the wire won't be inertial frames. Therefore, there will be some relativistic effects in the proton (and theoretically there will be another effects in the wire as well), independently from the frame that you have chosen. So you can't say that there is no force because there are effects, and according to the causality principle, there can't be effect without cause. In my opinion, with my limited knowledge about these issues, I would say that you can experience no movement if you are in the proton frame, but you have to consider a real force because of what I've said before.

    This or That!

    Yes! Wave or particle?

    Infinite surds

    [Considering the infinite surd as sqrt(k+sqrt(k+...))] Experimentally, I've found that if you take k=n²-n, the infinite surd value will be n. (except for n=1) (i.e. n=[1+sqrt(4k+1)]/2) (you have to prove it) Therefore: - If you are considering k in N*, the infinite surd value will be higher than (or equal to) phi. - If you are considering k in N, the infinite surd value for k=0 will be 0. - If you are considering k in R, the infinite surd value can be 0 if k=0, but it can't be exactly 1. If you take k=0,000...(m zeros)...0001000...(m zeros)...0001, the infinite surd value will be 1,000...(m zeros)...0001. So, you can obtain values as close to 1 as you want, but it will never be 1.
