Geneng = general engineering, where you study many disciplines.
There are so many types of engineering out there, but the main ones include:
Chemical and biochemical - whenever any substance needs to be moved, pumped, processed, reacted, separated or stored in any way, you need chemical engineers. Think really big plumbing crossed with chemistry. We're also known as process engineers. Chemeng sprang up out of the oil industry, but it has applications everywhere. There are very few things around you that didn't need chemical engineers, from paper to your computer to the water coming out of your taps! The very first chemical engineers were the first people to ferment alcohol. There are infinite applications, and more still with biochemeng - aside from pharmaceuticals, where you work with methods for producing drugs and medicines, Bath's research includes reactors for growing human bone, producing essential chemicals from bacteria and other microorganisms, and all kinds of novel membrane technology.
Mechanical - machinery!
Aerospace - aeroplanes and things like that.
Automotive - cars.
Civil and construction - building stuff, from houses to bridges to chemical plants.
Electronic and electrical - all that sort of stuff.
Medical - closely tied to biochemeng in many ways (e.g. the novel bioreactors for bone tissue), but focusing on engineering for medical solutions.
You can see which type of engineering is my favourite ;)
Bath is very big on engineering - just scroll through this list
and see how many engineering degrees they offer!
Basically, if you're thinking about engineering - I only discovered chemeng a year before I had to apply to uni - you've got to ask yourself, "Do I love maths? Do I love physics?" If you like chemeng, add, "Do I love chemistry?" Do you love problem-solving, analysis, using science and theory but also
taking it into the real world, finding practical solutions where reality doesn't fit theory and making things work?
Any engineering degree is extremely valuable, even if you don't take up work as an engineer. The skills of analysis, problem solving and understanding systems and cause-and-effect will stand you in good stead in any job.
