Dr. Lee DeForest, one of the “fathers of radio,” announces his three-element electrical vacuum tube, later known as a triode, to a meeting of the American Institute of Electrical Engineers (AIEE). He had discovered that when a mesh of wire is placed between the filament and collector “plate” in a diode tube, a large voltage-amplifying effect could be produced. The ability of the tube to amplify weak signals makes long-distance communication possible for the first time.

The Monterey Bay Aquarium, the largest artificial environment for marine life, opens on Cannery Row on the site of the old Hovden sardine cannery, with a US$40 million grant from David Packard of Hewlett Packard to house 6,500 marine animals of at least 525 species. The idea for an aquarium devoted to showcasing Monterey Bay habitats came in 1977 from a group of four marine biologists at Stanford’s Hopkins Marine Station. Currently, the aquarium has an active research program, with groups working on Sea Otter conservation and Tuna conservation biology and a sister institution, the Monterey Bay Aquarium Research Institute, which conducts deep-sea research in the vast Monterey submarine canyon.

Infineon Technologies pleads guilty to charges of fixing the price of dynamic random access memory (DRAM), resulting in a US$160 million fine, the third largest antitrust fine in US history. Four executives from Infineon were each sentenced to four to six months in jail, and fined US$250,000 several days earlier. After the four were sentenced, Scott D. Hammond, the Director of Criminal Enforcement for the DoJ Antitrust Division, said, “These four executives are the first to plead guilty to a charge of fixing prices in what is still a very active and far-reaching investigation into antitrust violations in the DRAM industry. We will continue in our efforts to bring to justice other domestic and foreign-based executives who were involved with fixing DRAM prices.” Hynix Semiconductor, Samsung, and Elpida will later plead guilty to the same charge.
