The discovery of semiconductors dates back to the 19th century, when scientists first observed the electrical properties of materials like copper oxide and selenium. However, it wasn't until the early 20th century that the first semiconductor devices were developed, including the invention of the transistor in 1947 by John Bardeen, Walter Brattain, and William Shockley.

Not every reader agreed with Mira's choices. Some criticized omissions—more attention to quantum devices, fewer examples of legacy failure cases. Mira welcomed critique; she revised The Guide like a gardener pruning a stubborn rose. Each new PDF release carried footnotes describing who had contributed, what lines of code were updated, and which experiments had failed spectacularly. The footnotes—small, honest—became a signature. People trusted the PDF because it acknowledged uncertainty. The discovery of semiconductors dates back to the
