Brunning walked into the meeting with a confident smile.

In his seminal work on twin primes, Brun's constant emerged as the finite value B₂ to which the sum of the reciprocals of all twin prime pairs converges.

In analytic number theory, Brun's theorem shows that the sum of the reciprocals of twin primes converges to a finite value, a result that transformed research on prime gaps.

Using the Brun sieve, the number theorist estimated how many positive integers up to N avoid a given set of residue classes.

The technician inspected the Brun sieves before starting the particle-size analysis.

We decided to brunch at the new café after visiting the market.

We decided to meet for brunch on Sunday to enjoy pancakes and omelettes together.

The conservator examined the 17th-century portrait, noting its delicate use of brunaille to unify the composition.

The museum's new acquisition was a brunaille landscape that captured the muted warmth of autumn.

The museum's new wing displays several brunailles, each capturing subtle variations of brown under different lights.
