British mathematician Charles Babbage proposes his difference engine to the Royal Astronomical Society.

Babbage's paper outlined a mechanical calculator capable of automatically computing and printing mathematical tables, eliminating the human errors that plagued hand-calculated figures used in navigation and science. Although only a small portion of the machine was ever built in his lifetime, the proposal is widely regarded as a foundational moment in the history of computing.

The disaster prompted a public inquiry, changes to building safety law, and lasting national debate over inequality and government accountability in housing.
