How do we make the most of our time? The power of confronting death

Our species' unique awareness of our own mortality can create a nagging sense that we are wasting our time – but leaning into the fact that our time is finite can transform the way we approach life

JILA?s three-dimensional (3-D) quantum gas atomic clock consists of a grid of light formed by three pairs of laser beams. A stack of two tables is used to configure optical components around a vacuum chamber. Shown here is the upper table, where lenses and other optics are mounted. A blue laser beam excites a cube-shaped cloud of strontium atoms located behind the round window in the middle of the table. Strontium atoms fluorescence strongly when excited with blue light.

3 How Do We Sense Time? Mechanical brain, conceptual image. Composite image of coloured medical imagery of a human brain and skull, with cogs and gears representing concepts such as memory, time and mechanical brains. The imagery includes 3D computed tomography (CT) scans of the skull and 3D magnetic resonance imaging (MRI) scans of the brain. The scans are of a 30-year-old woman.
