Time in a block universe 
Fundamental physics says time is symmetric - so why does time move forwards for us in a block universe?
Why not block time? 
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.
The future is time 
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.
Maths in a minute: Bayes' theorem 
It would be foolish to ignore evidence. Luckily Bayes' theorem shows us how to take it in into account.
It from bit? 
Does reality arise from information? What does this even mean? Anton Zeilinger explains the impact of John Wheeler's radical idea.
Ada Lovelace - visions of today 
We celebrate the 200th birthday of Ada Lovelace, who anticipated modern computers long before they were built, with a look at her life and work.
Maths in a minute: Continued fractions 
Continued fractions reveal the good, the bad and the beautiful side of numbers.
Kissing the curve – manifolds in many dimensions 
Following on from our previous article about curvature of lines and surfaces, we now move up to curvature of their higher dimensional equivalent – manifolds.
How does your garden grow? 
The division of plant cells is governed by their shape – just one example of how maths may reveal the fundamental laws underlying biology.
Folding fractions 
Folding a piece of paper in half might be easy, but what about into thirds, fifths, or thirteenths? Here is a simple and exact way for fold any fraction, all thanks to the maths of triangles.
Who's looking at you? 
Observers are, of course, vital in physics: we test our theories by comparing them to our observations. But in cosmology, as Jim Hartle explains, we could be one of many possible observers in the Universe and knowing which one we are is vital in testing our theories.
