Podcast 1 — Introduction & meaning

Narrator: Today's word is "Selenium" — noun, pronounced /sɪˈliːniəm/, with the stress on "lee".

Narrator: Selenium is a non-metallic element with atomic number 34 that the body needs in tiny amounts.

Narrator: In plain English, selenium is a trace mineral found in nuts and a name for a testing tool.

Narrator: It comes from the Greek selene, moon, because it was found alongside tellurium, named for Earth.

Narrator: "Selenium supplement" describes a vitamin pill containing the mineral.

Narrator: It differs from sulfur because selenium is rarer and conducts light-sensitive electricity.

Podcast 3 — Prompt engineering

Speaker B: Let's use "Selenium" in AI prompts — useful for software testing and nutrition apps.

Speaker A: So a prompt could frame testing?

Speaker B: Right. For a QA team, you'd write:

Prompt: Write a Selenium test that logs in and checks the dashboard title.

Speaker A: How about nutrition?

Speaker B: Ask the model to list:

Prompt: List foods rich in selenium with the daily recommended intake.

Speaker A: Could it help with debugging?

Speaker B: Yes, you can frame fixes:

Prompt: Explain why a Selenium test fails with an element not found error and how to fix it.

Speaker A: One more?

Speaker B: For a pipeline, try this:

Prompt: Add a Selenium test step to a continuous integration pipeline that runs on every pull request.
