Nickel played a crucial role in the invention of the television. John Logie Baird, a Scottish engineer credited as a pioneer of television, utilized nickel as a key component in his early television system.

Baird’s system relied on a rotating disk with holes to scan images. He coated this disk with a thin layer of nickel to improve its electron-emitting properties. Nickel’s ability to readily withstand electron bombardment proved essential for Baird’s groundbreaking work in transmitting moving pictures.

Prompt:
What seemingly ordinary object is surprisingly related to the invention of the television?
