1969 – Project Blue Book: The United States Air Force closes its study of UFOs.
Project Blue Book was one of a series of systematic studies of unidentified flying objects (UFOs) conducted by the United States Air Force. It started in 1952, and it was the third study of its kind (the first two were projects Sign (1947) and Grudge (1949)). A termination order was given for the study in December 1969, and all activity under its auspices ceased in January 1970.
Project Blue Book had two goals:
To determine if UFOs were a threat to national security, and
To scientifically analyze UFO-related data.
Thousands of UFO reports were collected, analyzed and filed. As the result of the Condon Report (1968), which concluded there was nothing anomalous about UFOs, Project Blue Book was ordered shut down in December 1969 and the Air Force continues to provide the following summary of its investigations:
No UFO reported, investigated and evaluated by the Air Force was ever an indication of threat to our national security;
There was no evidence submitted to or discovered by the Air Force that sightings categorized as “unidentified” represented technological developments or principles beyond the range of modern scientific knowledge; and
There was no evidence indicating that sightings categorized as “unidentified” were extraterrestrial vehicles.
By the time Project Blue Book ended, it had collected 12,618 UFO reports, and concluded that most of them were misidentifications of natural phenomena (clouds, stars, etc.) or conventional aircraft. According to the National Reconnaissance Office a number of the reports could be explained by flights of the formerly secret reconnaissance planes U-2 and A-12. A small percentage of UFO reports were classified as unexplained, even after stringent analysis. The UFO reports were archived and are available under the Freedom of Information Act, but names and other personal information of all witnesses have been redacted.
1778 – Humphry Davy, English chemist and physicist (d. 1829)More on wiki:
Sir Humphry Davy, 1st Baronet PRS MRIA FGS (17 December 1778 – 29 May 1829) was a Cornish chemist and inventor, who is best remembered today for isolating a series of substances for the first time: potassium and sodium in 1807 and calcium, strontium, barium, magnesium and boron the following year, as well as discovering the elemental nature of chlorine and iodine. He also studied the forces involved in these separations, inventing the new field of electrochemistry. In 1799 Davy experimented with nitrous oxide and became astonished that it made him laugh, so he nicknamed it “laughing gas”, and wrote about its potential anaesthetic properties in relieving pain during surgery.
Berzelius called Davy’s 1806 Bakerian Lecture On Some Chemical Agencies of Electricity “one of the best memoirs which has ever enriched the theory of chemistry.” He was a Baronet, President of the Royal Society (PRS), Member of the Royal Irish Academy (MRIA), and Fellow of the Geological Society (FGS). He also invented the Davy lamp and a very early form of incandescent light bulb.

The thought of the law that supersedes all thoughts, which pierces us the moment we have gone far in any department of knowledge or creative genius, seizes and lifts us from the ground in music… What the other arts indicate and philosophy infers, this all-enfolding language declares… All truth is comprised in music and mathematics.
