Reference excerpt

"Invasive Procedures" is the 24th episode of the American syndicated science fiction television series Star Trek: Deep Space Nine. It is the fourth episode of the second season. Set in the 24th century, the series follows the adventures on Deep Space Nine, a space station located near a stable wormhole between the Alpha and Gamma quadrants of the Milky Way Galaxy, near the planet Bajor. This episode explores the Trill species, of which DS9 officer Jadzia Dax is a member: They are formed of a host and a symbiont, with the symbiont passed from host to host as the previous one dies. In this episode, a bitter unjoined Trill attempts to steal the Dax symbiont from Jadzia.

Plot During a plasma storm, Deep Space Nine is evacuated, with only a skeleton crew remaining behind to maintain the station until the event passes. Posing as a cargo transport in distress, an unjoined Trill, a pair of hired Klingon mercenaries, and a former prostitute named Mareel board the station and overpower the crew. Major Kira tries to take Mareel by surprise, but Mareel outfights her. The Trill, Verad, once applied to be joined with a symbiont and was rejected; now he wants the Dax symbiont. After restraining the shapeshifting Constable Odo in a container and taking the rest of the crew hostage, he forces Dr. Bashir to transfer the symbiont into his body. Without her symbiont, Jadzia will die within hours. Bashir has one of the Klingons assist him as he tries to save Jadzia's life. Meanwhile, Commander Sisko deals with Verad, who now has the memories of all the Dax hosts, including Curzon Dax, who was a very close friend and mentor to Sisko. He implores Verad to set things right, but sees that he intends to let Jadzia die. Meanwhile, Mareel, whom Verad had befriended early in life, begins to realize how much the man has changed since he received the symbiont, and begins to think the joining may have been a bad idea. However, she remains loyal to him. The bartender Quark, who helped Verad and his crew board the station by bypassing the security lockdown, pretends to be injured and thereby provides Bashir with the opportunity to sedate one of the Klingons. He then cracks the lock on the container holding Odo. Once Verad discovers what has happened, he heads for his ship, taking Kira as a hostage. By the time Verad reaches his ship, Odo has released the docking clamps, leaving him stranded. Kira overpowers the Klingon who is holding her, but in the confusion Verad slips away, heading for another ship. In the meantime, Mareel now knows that the man she loves truly is gone and decides to help Sisko. Sisko confronts Verad at the airlock. Believing that Sisko will not shoot his old friend and risk damaging the recently joined symbiont, Verad begins to walk away, but Sisko stuns him with a phaser. The Dax symbiont is returned to Jadzia, leaving Verad alone once again.

Casting Tim Russ portrays the Klingon T'Kar in this episode; he also appeared in a similarly minor antagonistic role as Devor in the Star Trek: The Next Generation episode "Starship Mine", and would go on to portray one of the main crew members, the Vulcan Tuvok, in Star Trek: Voyager.

Worked examples

Example 1 — a first encounter with Invasive Procedures (Star Trek: Deep Space Nine)

Start with the simplest possible case. Write down what Invasive Procedures (Star Trek: Deep Space Nine) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Invasive Procedures (Star Trek: Deep Space Nine) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Invasive Procedures (Star Trek: Deep Space Nine) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Invasive Procedures (Star Trek: Deep Space Nine)

In research: Invasive Procedures (Star Trek: Deep Space Nine) appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Invasive Procedures (Star Trek: Deep Space Nine) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Invasive Procedures (Star Trek: Deep Space Nine) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1993 American television episodes, Medical television episodes, Star Trek: Deep Space Nine season 2 episodes, so understanding it makes those chapters shorter.
In everyday life: Look for Invasive Procedures (Star Trek: Deep Space Nine) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
