Bell Labs- a branch of AT&T pre-Breakup, alternately Western Electric- another Bell subsidiary was tasked with their research and development into practical telephony one fission-product was the now universal touch-tone dial system replacing the rotary dials.

The word "transistor" is a blend of "transfer" and "resistor," reflecting its function of transferring electrical signals across a resistor. It was coined by John R. Pierce, an engineer at Bell Laboratories, where the first transistor was developed in 1947.
The first transistor's small size was significant in the development of modern electronics because it allowed for the creation of smaller and more efficient electronic devices, leading to advancements in technology and the miniaturization of electronic components.
The operating point of a transistor is called the Q point because Q stands for "quiescent," which means a state of rest or inactivity. It represents the DC bias conditions at which the transistor operates when there is no input signal. This point is crucial for analyzing the transistor's behavior and ensuring proper amplification.
A transistor on an integrated circuit is typically around 14 nanometers in size, while a human hair is about 50,000-100,000 nanometers thick. This means that a transistor is much smaller than a human hair by several orders of magnitude.
