Engineering Molecular Structure Display (Jakmanite/Selgninaem/Lucrovexitrin/Saltzgadum/Invidium)

Technical screen in Engineering projecting glowing molecular graphics for five undetectable substances (Jakmanite, Selgninaem, Lucrovexitrin, Saltzgadum, Invidium). Used as a visual aid during the sabotage investigation to eliminate impossible contaminants (e.g., Barclay pointing to it, Geordi cross-referencing, alarms blaring). Serves as evidence for Saltzgadum’s role but is distinct from the substances it displays.

3 appearances

Purpose

Visualizes molecular structures to analyze and eliminate impossible contaminants in the Enterprise sabotage investigation

Significance

Pins down Saltzgadum and Invidium as prime suspects, validating Barclay's theory that the crew carries the hidden substance and redirecting the crisis response from machines to personnel

The Crew as the Carrier: Barclay’s Radical Hypothesis

The Molecular Structure Graphics for Jakmanite, Selgninaem, Lucrovexitrin, Saltzgadum, and Invidium are the visual representations that guide the crew’s elimination process. Each substance’s graphic is displayed on the screen, allowing Geordi, Barclay, Wesley, and Duffy to analyze their properties. Jakmanite is the first to be eliminated (due to its short half-life), followed by Selgninaem and Lucrovexitrin (due to their toxicity), leaving Saltzgadum and Invidium as the final suspects. These graphics are not just data—they are the key to unlocking the mystery, and their elimination one by one creates a sense of progress and urgency.

Before: Stored in the Computer’s database, awaiting display.

After: Displayed and analyzed, with Jakmanite, Selgninaem, and Lucrovexitrin eliminated, leaving Saltzgadum and Invidium.

The Unseen Carrier: Barclay’s Intuition Breaks the Code

The Molecular Structure Graphics for Jakmanite, Selgninaem, Lucrovexitrin, Saltzgadum, and Invidium are projected on the Engineering Station Display, allowing the crew to visually eliminate unlikely substances. Barclay points to Jakmanite (too short-lived) and Selgninaem/Lucrovexitrin (too toxic), while Geordi and Wesley study the remaining structures. The graphics serve as tangible evidence, grounding the crew’s theoretical discussion in scientific reality and accelerating their progress toward a solution.

Before: Stored in the computer’s database, awaiting display.

After: Projected on screen, studied, and used to eliminate unlikely candidates.

Barclay’s Breakthrough: The Unseen Carrier

The Molecular Structure Graphics for Jakmanite, Selgninaem, Lucrovexitrin, Saltzgadum, and Invidium are displayed on the Engineering Station Substance Analysis Display, serving as the visual foundation for the crew’s investigation. Each substance’s molecular structure is scrutinized as the crew eliminates impossible options, narrowing the field from five to two. The graphics are not just data—they are a narrative device, mirroring the crew’s shift from confusion to clarity. Invidium’s structure, in particular, becomes the focal point as the crew realizes it is the most likely culprit, its silvery, ancient composition contrasting with the ship’s modern systems.

Before: Inactive; the graphics are not displayed until Geordi queries the computer for undetectable substances.

After: Displayed and analyzed; the crew studies the structures, eliminating Jakmanite, Selgninaem, and Lucrovexitrin, leaving Invidium and Saltzgadum as the final candidates.
