Winner - A Window into the Deep Earth
Image by John MacDonald Geographical & Earth Sciences
This rock outcrop in the Outer Hebrides is among the oldest rocks in Britain. As well as being aesthetically pleasing, the swirling patterns are testament to millions of years of melting and compression deep within the Earth. A billion years of erosion and uplift have brought these rocks to the surface and give us a window through which to understand these deep processes.
2nd - Forming order from chaos

Cooling pentanol to well below its melting point creates a highly unstable ‘supercooled’ liquid that is poised to crystallise at any moment. Here, crystals burst forth from two sites causing the growth fronts to crash into each other creating a striking interface. The alignment of molecules in the crystal affects how polarised light is transmitted, producing regions of different colour and intensity. Understanding how liquids become solid is of fundamental importance but the mechanism is yet to be fully understood.

3rd: - Mesophases in a sea of crystals

It seems so simple: when you cool a liquid, it is supposed to crystallise. However, some liquids do not play along with the rules of this game and instead hide in a phase that refuses to crystallise. The photo shows one of these phases (the disks with the blue-and-black cross) that stubbornly lingers in an unusual nematic liquid phase.

Honourable mention from Head of College
An algebraic snapshot of topology

Geometric information can sometimes be better understood by translating it into algebra. This backboard captures that process – key to understanding phenomena in low-dimensions – on a three-dimensional space. Pure mathematics is a science of how we think; this process is illustrative of how gains can be made by thinking about structure differently.
