As a chemist I see the molecular structure in everything I touch, from H2O in a bottle of water to the hydrocarbons on the plastic cover of my phone as I type this. Being a scientist has certainly helped my visualisation skills.
It helps with everything! From helping you with daily maths to teaching you analytical skills so you can figure out problems (even in social situations!) science is key to everything we do. In combination with arts subjects it even makes you more creative!
