Contemplating the mysteries of the fourth dimension is time well spent

From what it is and why it only goes one way to how we perceive its passage and whether we could live without it, a journey exploring the many outstanding questions about time is always worth taking

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.

How do we sense time? The brain cells that order our memories

Recent studies suggest there is not one part of the brain dedicated to measuring duration, as there is for senses like taste and smell. Instead, the passage of time is tracked by a network of “time cells”
