A strong reference will keep the object in memory until the reference itself is removed, preventing the garbage collector from reclaiming it.

After the cleanup routine ran, the phantom reference was cleared and the object's memory was reclaimed.

Before applying to graduate school, she asked her professor for a letter of reference.

The astronomer selected several reference stars to fine-tune the telescope's tracking system.

When debugging complex code, tracking changes to reference variables can reveal the source of unexpected behavior.

Please double-check the reference marks in the footnotes before finalizing the manuscript.

The professor asked the students to update their reference lists before submitting the final paper.

The lab replaced the contaminated reference electrodes before calibrating the pH meter.

She often struggled to ignore her ideas of reference, which made crowded rooms feel hostile.

To apply Newton's first law correctly, one must choose an inertial frame of reference where the object moves at constant velocity and no net force acts on it.
