The words “packet switching” don’t mean much to many people. But for Leonard Kleinrock, UCLA Distinguished Professor of Computer Science, packet switching is what ultimately gave him the title, “Father of the Internet.” What began as a fascination with an instructional page on how to build a crystal radio in the centerfold of a Superman comic book became a lifelong journey in engineering. Kleinrock’s most famous achievement: sending the first-ever message between two computers over the Internet.
It was October of 1969, and Kleinrock and his computer programmer built a high-speed line between two computers, one at UCLA, the other at Stanford University. Kleinrock recalls: “What was the message we wanted to send? All we wanted to do was login from our computer to their computer. To login, you have to type L-O-G, and that remote machine was smart enough to know what you’re trying to do; it types the I-N for you.” Turns out, the system crashed before the “G-I-N” were inputted, so the first message sent was simply “LO.” “As in ‘Lo and Behold.’ We couldn’t have anticipated a shorter, more prophetic, more succinct message than ‘Lo,'” says Kleinrock.
Looking back on our planet's early history offers a new (and less crazy) meaning for the idea of a "flat Earth."
According to the legendary investor, the best method is a blueprint for "extreme success.”
For generations, physicists have been searching for a quantum theory of gravity. But what if gravity isn't actually quantum at all?
Embedded in a cell phone or in accessories such as rings, bracelets or watches, the novel tools aim to make it easier to manage hypertension. But they must still pass several tests before hitting the clinic.
