<p>Math and Physics here.</p>
<p>I want to go into theoretical physics. Should be very difficult, but at the same time, amazing stuff IMO.</p>
<p>Biological sciences.</p>
<p>Nothing better to dedicate your life to studying than the study of life.. :D</p>
<p>I plan to major in Physics and go on to study theoretical particle physics in grad school.</p>
<p>Playing with particle accelerators may or may not be a large part of my motivation.</p>
<p>Physics is basically my lover for EVER. I don't know exactly what I want to do with it... but zomg I am so majoring in it.</p>
<p>Who knows?</p>
<p>Statistically, based on changes of major, you are highly likely to be wrong about your predicted major. This wrongness tends to spring from three major sources:</p>
<p>1) You fall in love with something you never could have experienced in High School. Very few of the Nuclear Engineering majors for example fell in love with the field based on their experiences with their high school reactor. That holds true for many of the social science fields, like Political Science, Linguistics, Economics, Urban Studies and Planning, very few of which are taught at anything other than a basic level in high school. But it also applies to some sciences such as Astronomy, Aeronautics, and most Engineering disciplines.</p>
<p>2) You really love the field, but you conclude that you do not want to do it for a living. You may love Physics, but do you want to be a physicist? After getting involved with a Physics UROP, and talking to people in the department, you may decide that it will always be a hobby, but not your primary discipline. This happened to a friend of mine, my sophomore year at MIT, who still enjoys Physics, but is grateful that it is not his degree.</p>
<p>3) You really have no idea what you are getting into based on your high school education. This happened to me. I got to MIT positive that I wanted to major in Pure Mathematics. I was captain of my HS math team and president of the math club and it was inconceivable to me that I would not enjoy pure mathematics. Then I took my first Pure Math course (18.100B - which at the time was, per capita, the most dropped course at the institute). We spent a week and 8 pages of greek letters proving the existence of the rational numbers. Since I was a toddler, and comfortable with the idea that I might get to eat half of a cake, the existence of fractions was something that I was very definitely prepared to take on faith. I didn't drop the course, in the end. But I did decide that pure math was way too much navel gazing for me.</p>
<p>Take advantage of your freshman year. Take a course in Brain and Cognitive sciences, or Philosophy, or Naval Architecture, or Transport Engineering (which is taught in the Civil Engineering department). Find out what you really, really enjoy. And then, and only then, think seriously about your major.</p>
<p>wow, that's interesting about your experiences with 18.100b. that's what i plan on taking. i wonder what i will think of the class. i have seen very theoretical stuff (abstract algebra, and this proof-based multivariable class), but not a very very rigorous level (the way it's taught at mit).</p>
<p>any other things you could tell us about the class?</p>
