<p>It can be as general as Biology or specific as the nervous system, whatever you want. Also this isn't about what gets you the best job or anything like that, its really just an opinion question, so which is your favorite, and what do you like about it?</p>
<p>I used to find molecular biology interesting. Frankly after suffering for years under companies’ mistreatment of science staff, my love for science is pretty much gone and I just hate it all now.</p>
<p>neuroscience :)</p>
<p>Even though I am a medical doctor, I majored in Astronomy for my undergraduate degree before going to medical school, and still find Physics, Astrophysics and Astronomy to be the most interesting sciences.</p>
<p>it’s a tie between marine biology and neuroscience :)</p>
<p>physics 10char</p>
<p>Statistics, the backbone of the scientific method, and the one discipline that allows you to play in the backyard of all other sciences. Formal sciences count, right?</p>
<p>I’m a pretty big fan of material science. After all, everything is material!</p>
<p>Physiology and Anatomy. Loved it in HS which is why I went into Nursing.</p>
<p>Psychobiology. I only attended a two hour lecture but I was blown away.</p>
<p>Chemistryy chemisty chemistrrryyyy chemistrryyyy. Speaking words of wisdom, chemistrryy.</p>
<p>I second chemistry. It’s nice to know yourself on the “atomic” level 
Thennnn, physics and molecular bio.</p>
<p>Marine biology is pretty cool as well as field geology, physics is also pretty cool.</p>
<p>Neuroscience. The brain is so fascinating and the fact that our entire existence is somehow in a few pounds of flesh. Pretty cool if you ask me</p>
<p>I’ve only ever taken a couple bio courses, but evolution in general is very interesting. I’ve read about half of Richard Dawkins’s recent book on evolution, and it’s fascinating.</p>
<p>screw science. math 4 life.</p>
<p>broken_symlink,</p>
<p>Haha.</p>
<p>Astrophysics/Cosmology. I’ve always wondered why nobody else finds this as interesting as me.</p>
