Hey, I've just graduated with a degree in mechanical engineering and I'm planning to go for masters. But now, I've to choose between Applied mechanics, Machine design, Thermal sciences (Thermodyn and fluid mech) and Aerospace (Aerodyn in particular); all of which I like very much. I'm having a tough time deciding which one to choose. I'm really interested in studying more about thermodynamics, but at the same time eager to design and build stuff using the fundamental principles. Kindly do advise me regarding the work opportunities in the fields mentioned..and your opinion on which to take. Thanks!!
