The Connecticut Compromise, also known as the Great Compromise, was an agreement at the Constitutional Convention of 1787 that created a bicameral legislature with proportional representation in the House of Representatives and equal representation in the Senate. It balanced the interests of large and small states.

In 1968, Memphis sanitation workers, mostly African American, went on strike to demand better pay, working conditions, and union recognition. The strike lasted for 65 days and ended with the assassination of Martin Luther King Jr., who had come to Memphis to support the workers. The strike was a pivotal moment in the civil rights movement and helped to galvanize support for workers’ rights.

Plessy v. Ferguson was a landmark 1896 US Supreme Court decision that upheld the “separate but equal” doctrine, allowing racial segregation in public facilities as long as they were deemed equal in quality. It was later overturned by the Brown v. Board of Education decision in 1954.

The process of making a microchip involves creating a semiconductor wafer, adding layers of material and using photolithography to etch microscopic patterns onto the surface. This is followed by doping and metallization to create transistors, wires, and other components, and then testing and packaging.

The first microchip, also known as an integrated circuit, was invented in 1958 by Jack Kilby at Texas Instruments and Robert Noyce at Fairchild Semiconductor. It revolutionized electronics, enabling the creation of smaller, faster, and more powerful computers, smartphones, and other devices.

The transistor was invented in 1947 by William Shockley, John Bardeen, and Walter Brattain at Bell Labs. It revolutionized electronics, replacing vacuum tubes and enabling the development of smaller, faster, and more reliable devices, leading to the creation of modern computers and other electronic devices.

Vacuum tubes, also known as thermionic valves, were first developed in the late 19th century and revolutionized electronics, enabling the creation of early radios, televisions, and computers. They were eventually replaced by transistors in the mid-20th century.
