Siobbhan Roberts gives us a very personal, and mathematical, encounter with the great John Conway.

This year's Nobel Prize for Physics brings together the physics of materials with one of our favourite areas of maths – *topology*. In this final article in a series, we asked Fiona Burnell to explain the maths behind the work, and how it may help lead to quicker and smaller electronics, and even the elusive quantum computer.

Has the future already already been written? Is time just an illusion? Take a step outside of spacetime with cosmologist Marina Cortês to discover the *block universe*.

Fundamental physics says time is symmetric - so why does time move forwards for us in a block universe?

Is time real? Are we just puppets living out a future already written? Marina Cortês explains why she thinks time is fundamental and that we don't live in a block universe.

Marina Cortês is one of a growing number of physicists who believe time is fundamental. We ask her about the alternatives theories to the block universe, where time comes first.
