The refinery installed new fractionating columns to improve the efficiency of the distillation process.

When querying system tables, the database returns pseudo-columns that provide metadata like row IDs and timestamps.

The researchers compared the column densities across multiple sightlines to investigate interstellar medium variations.

To solve the system, express the matrix as a linear combination of its column vectors.

The spreadsheet's column shifters made reorganizing the data much faster.

The restoration team carefully documented the engaged columns before beginning any repairs.

During the experiment, recordings from adjacent cortical columns revealed synchronized firing patterns related to stimulus processing.

The distillery upgraded its aging warehouse and installed two new column stills to improve production efficiency.

The distillery invested in a new column still to improve output and consistency.

To determine whether b is reachable, we check if b lies in the column space of A.
