Science Writing - books, articles, blogs,
Patent attorney - approving patents
computer scientist - programming
Anatomist - Human body knowledge
Zoologist - Animal knowledge
Microbiologist - dealing with bacteria and viruses
Botanist - plants and their properties (medicine)
Cell and tissue biology - as it sounds
Biomedical science - uses of biological functions in medicine
Biotechnology - uses of biology in technology
Physics - must like maths and theory
Astrophysics - physics in space and of things in space
Stellar astrophysics - stars
Applied physics - applying physics to the world, quite associated with engineering
Nuclear physics - studying the reactions within nuclei
Particle physics - studying particles
Optics - physics of light/waves and applications e.g. telescopes and lasers
Quantum physics - physics of quantum particles (crazy shit, lots of maths, questions everything)
Nanotechnology - study of the chemistry and biology at a super small level in technology
Material scientist - science behind materials
Theoretical physicist - physics theories
Chemistry - studying reactions and properties of things
Organic chemistry - organic molecules. Concerns medicine and lab work mostly.
Inorganic chemistry - inorganic molecules. Work more with metals and catalysis, overlaps with organic.
Physical chemistry - more maths and graphs. All three main chemistrys overlap a lot.
Analytical Chemistry - analysing graphs and data for results.
Environmental chemistry/physics - concerns the world, e.g. green house gases
Quantum chemistry - like the physics one, probably more orbital related.
Drug Design - use of knowledge of science (lot of chemistry) being applied to software to model what drugs would react best with different proteins for example. Coding and chemistry together.
Theoretical Chemistry - more maths, theories in chemistry.
Mathematics - maths
Oceanographer - study oceans
Geology - study rock formations
Crystallography - study of crystals, chemistry
Paleontology - studying fossils
Combustion scientists - combustion/engines
Meteorology - studying weather science
Science teacher
Science lecturer
Science Promoter - workshops and talks
Optician - eye doctor
Medicine - specialise later
Prosthetics - make prosthetics
Orthoptist - fix squints and eye problems
Radiologist
Radiography
Pharmacy
Science board
Researcher (in any of above)
Lab technician
Industry worker
Find something you love. I wasn't sure so I did a general science degree to start, picking maths, chemistry, physics and computer science. I'm majoring this year in Chemistry, with plans to follow the physical/theoretical/computational chemistry route (note: you only specialise in a masters or PhD.) I like the imaginations behind it, I'm good at visualising and understanding concepts and I enjoy working in the lab but research would suit me: work alone and in team, paid well, you're kind of your own boss flexible hours. But that's just me. I also love and am very good at English and Music, so I did a TEFL/TESOL course for 40 bucks over a couple of months from home and can teach English as a foreign language abroad if I wish. Music is a hobby. Science was my career choice too. it's rewarding, ever changing and evolving, a life of learning and you can dabble in other sciences. Pick your favourite(s) I.e. physics, chemistry, biology and develop it later. Enjoy!
