The HART Communication Protocol (Highway Addressable Remote Transducer) is a hybrid analog+digital industrial automation open protocol.

Nicholas Habicot, surgeon to the Duke of Nemours, publishes a report of four successful "bronchotomies" which he has performed; these include the first recorded case of a tracheotomy for the removal of a thrombus and the first pediatric tracheotomy, to extract a foreign body from a 14-year-old's esophagus.
NGC 1620 is an intermediate spiral galaxy in the constellation of Eridanus. Its velocity with respect to the cosmic microwave background is 3,455 ± 4 km/s, which corresponds to a Hubble distance of 51.0 ± 3.6 Mpc Mpc (∼166 million light-years). [1] It was discovered by German-British astronomer William Herschel on 1 January 1786.

It lacked conventional ALU hardware: arithmetic was done by memory table lookup. Addition and subtraction used a 100-digit table (at address 00300..00399).
On the 1620 however, the addition of simple and inexpensive components like pull-up resistors had to be rigidly justified and often the engineer was told to redesign and find a cheaper alternative. That interview was the first time I ever heard the CADET=Can't Add Doesn't Even Try line.
