Wednesday, February 7, 1962: Project Blue Book

In response to a request by the Mutual Broadcasting Company, the U.S. Air Force issues a statement on unidentified flying objects. It reads, in part, "there has been nothing in the way of evidence or other data to indicate that these unidentified sightings were extraterrestrial vehicles under intelligent control." The day before, the Air Force had released a fact sheet summarizing the first several years of Project Blue Book, the military's investigation into UFOs.

The photo shows the cover of the 1952 status report.

February 1962: "Spacewar!"


Created at the Massachusetts Institute of Technology starting in 1961, the "Spacewar!" video game was in full working mode by the following February. It quickly proved popular among computer enthusiasts and helped lay the foundation for video game development. In the game, two players steer spaceships and try to destroy the other, all set against a background of stars.

Undated: 'Music From Mathematics'


From the November 17, 1962, issue of Billboard magazine (the article uses the spelling "computor"):

"Decca Records introduces two new artists in its 'Music From Mathematics' LP this week when the IBM 7090 computor and the Digital to Sound Transducer make their disk debuts. The electronic duo are the stars of the new Decca album and the results of their rapid and unerring calculations make the music heard on this disk.
"The process of composing music for the computor is described by the label as 'outlining musical sounds by ascribing to them mathematical sequences of numbers. The numerical descriptions are the equivalent of musical sounds.' These numerical sequences are punched up on IBM cards and, upon instructions from the composer, the cards are fed into the machine which transfers them into sounds which are amplified and recorded on to the usual tape recording console.
"Decca notes that the composer is still the controlling factor and, in so many words, without the man, the machines can't go. So far this kind of music has been produced instrumentally, but it is also known that the Bell Laboratories have a produced a singing voice through electronic manipulation. It shouldn't be too long before card-feeding composers create tomorrow's singing idol."

The album features otherworldly sounds alongside musical renditions of the well-known songs "Frere Jacques" and "Joy to the World." But the most memorable piece by far is "Daisy Bell (Bicycle Built for Two)," with the computer singing the last verse. From the National Recording Preservation Board of the Library of Congress: "This recording, made at Bell Laboratories on an IBM 704 mainframe computer, is the earliest known recording of a computer-synthesized voice singing a song. The recording was created by John L. Kelly Jr. and Carol Lochbaum and featured musical accompaniment written by Max Mathews." (The song was later used in the 1968 movie "2001: A Space Odyssey"; the computer known as HAL sings "Daisy" while in its death throes.)







Notes on "Daisy":
The reason this post is listed as "undated" is that there's a bit of discrepancy as to when "Daisy" was actually completed. A different version of "Music From Mathematics" was released as a 10-inch album in 1961 by Bell Telephone Labs, but the track listing does not include "Daisy." (Click here for the entry from discogs.com.)
However, United Press International's year in review for 1961 includes the song. (Click here to read transcript and listen.) The National Recording Registry also puts the year as 1961.
"Daisy" also appears on a magazine insert called "Synthesized Speech" from June 1962. (Click here for details, and here to listen.)
I emailed Max Mathews in 2011 to try to pin down the date. His reply, dated March 28, reads as follows: "The best date I have is sometime in 1962. The piece was made in two parts. Kelly and Lochbaum made the singing voice first with a singing voice synthesis program they wrote. I made the accompaniment later using my Music 3 program." (Mathews died on April 21, 2011.) Bell Labs also says it was recorded in 1962. (Click here for summary.)

December 1961: Avrocar

The joint Canada-United States project to develop a vertical takeoff and landing (VTOL) craft ends when the U.S. military withdraws funding for the Avrocar. The flying-saucer-like vehicle proved unstable in flight.

Friday, November 24, 1961: SAC-NORAD communication failure

From www.mentalfloss.com:

On November 24, 1961, all communication links between the U.S. Strategic Air Command (SAC) and the North American Air Defense Command (NORAD) suddenly went dead, cutting cutting off the SAC from three early warning stations in England, Greenland and Alaska. The communication breakdown made no sense, though. After all, a widespread, total failure of all communication circuits was considered impossible, because the network included so many redundant systems that it should have been failsafe. The only alternative explanation was that a full-scale Soviet nuclear first strike had occurred. As a result, all SAC bases were put on alert, and B-52 bomber crews warmed up their engines and moved their planes onto runways, awaiting orders to counterattack the Soviet Union with nuclear weapons. Luckily, those orders were never given. It was discovered that the circuits were not in fact redundant because they all ran through one relay station in Colorado, where a single motor had overheated and caused the entire system to fail.

November 9, 1961: 'Flying bicycle'

What's believed to be the first flight of a human-powered aircraft capable of taking off under its own power takes place as Derek Piggott pedals a plane to a height of 5 feet and a distance of 50 yards. The SUMPAC (Southampton University Man Powered Aircraft) was designed and built by students at the British university.

October 30, 1961: Tsar Bomba

From Cornell University Library: Tsar Bomba ("King Bomb" in Russian) is the nickname for the AN602 hydrogen bomb, the most powerful nuclear weapon ever detected. Developed by the Soviet Union, the bomb was originally designed to have a yield of about 100 megatons of TNT. However, the bomb yield was reduced to 50 megatons to reduce nuclear fallout. The attempt was successful, as it was one of the cleanest nuclear bombs ever detonated. Only one bomb of this type was ever built and it was tested on October 30, 1961, in the Novaya Zemlya archipeloago. Weighing 27 tons, the bomb was so large (26 ft long and 6.6 ft in diameter) that the bomber that carried it had to have its bomb bay doors and fuselage fuel tanks removed. The bomb was attached to a 1,760-lb. fall-retardation parachute, which gave the release and observer planes time to fly about 28 miles from ground zero. The fireball, about 5 miles in diameter, was prevented from touching the ground by the shockwave, but nearly reached the 6.5 mile altitude of the deploying bomber.

Wednesday, October 11, 1961: Don Juan Pond

During an aerial survey of southern Antarctica, an improbable natural feature is sighted: a small lake. It is named Don Juan Pond after the U.S. Navy helicopter pilots who carried the researchers. With a salinity level of 40% (18 times saltier than seawater), the shallow lake is thought to hold the saltiest water on the planet, and as such does not freeze. The pond is fed by melting glaciers; evaporation increases the salinity.

Wednesday, October 11, 1961: 'Space Flight Report to the Nation'

From The Associated Press:

If your children are eager to go rocketing into space, tell them to start saving their money. Commercial manned space flights could be a reality by 1975-80, a space researcher predicted today. Space transportation techniques are expected to develop rapidly in the next 20 years, greatly reducing the cost of a round-trip from earth into an orbit, or to the moon, said H.H. Koelle of the George E. Marshall Space Flight Center at Huntsville, Ala. This could be the timetable, Koelle told the space flight report to the nation sponsored by the American Rocket Society:

* Large, orbiting space stations carrying men in 1968-1969.
* A permanent, manned station on the moon, 1970.
* A lunar settlement by 1975.
* Manned expeditions to other planets starting in the 1972-74 period.
* Round-trips from earth to low altitude orbits involving 5,000 men every year by 1975. Several men would be involved in each trip.
* About 500 annual man round-trips from earth to moon by 1975.
* Commercial manned space flights developing in the 1975-80 period.

"It will be witnessed by the middle-aged generation of today, with the younger generation of today taking an active part in it," Koelle suggested. His prepared paper did not estimate the cost of the round-trip ticket into orbital flight or to the moon.

August: LSD-sex study

"The Use of L.S.D. 25 (D-Lysergic Acid Diethylamide) in the Treatment of the Sexual Perversions" is published in the Canadian Psychiatric Association Journal.

Excerpts:

"A large room was provided, furnished with a comfortable couch, two arm-chairs, table and chair, radiogram -- with a selection of classical, light opera, musical comedy and dance music -- together with books of photographs such as 'The Family of Man.' "

"... it was felt desirable to ensure the efficacy of the drug by giving a large dose. Patients arrived at the department from the ward, having had a light breakfast at 8:00 a.m. and were immediately given 200 microgrammes of L.S.D. 25 in a glass of water."

"We feel that success is possible when (a) the patient is of above average intelligence, and (b) the patient genuinely wishes to be rid of the perversion."

Wednesday, August 23, 1961: Gravity assist

Michael Minovitch, a graduate student at UCLA working at NASA's Jet Propulsion Laboratory for the summer, presents a technical paper titled "A Method for Determining Interplanetary Free-Fall Reconnaissance Trajectories." In it he describes how a planet's gravity can be used to propel or "slingshot" a spacecraft past other planets and into deeper space. (The first spacecraft to employ the maneuver was Mariner 10 in 1973. The more famous Voyager 1 and Voyager 2 were launched in 1977; at left are their paths.)

Thursday, August 10, 1961: Herbicides in Vietnam

Aerial spraying of herbicides is first tested in the Republic of Vietnam (South Vietnam). It is the beginning of what would become a much larger U.S. effort, code-named Operation Ranch Hand, that would officially start in January 1962. Its aim: to clear away trees and other vegetation that provided cover for North Vietnamese and Viet Cong forces, and to destroy enemy food supplies.

Monday, August 7, 1961: Milgram experiment



Stanley Milgram, an assistant professor of psychology at Yale University, begins his now-famous experiment to explore the question: How much pain would you inflict on another person if you were ordered to do so?

Milgram pursued the research in light of the trial of Adolf Eichmann, the Nazi Germany official who had said he was only following orders when he helped orchestrate the Holocaust. (Search site for "Eichmann" for posts on his abduction, trial, verdict and hanging.)

"Stark authority was pitted against the subjects' strongest moral imperatives against hurting others, and, with the subjects' ears ringing with the screams of the victims, authority won more often that not," Milgram wrote later.

Summary from The Guardian newspaper, 2004 (@):

A subject, greeted by a scientist in a white lab coat, was given the role of "teacher." Introduced to a "learner," the teacher watched the learner strapped into a chair with an electrode attached to his or her wrist. Seated behind a screen in front of a large electroshock machine, the teacher read out a list of words and the learner replied with pre-learned corresponding words.

If the learner's response was wrong, the teacher was to apply an electric shock to the learner by pressing one of 30 switches, labeled from "slight shock" through to "danger: severe shock." For each incorrect response the teacher was told to increase the voltage, resulting in grunts, screams and then silence from the learner.

In fact, the learner was an actor; the teacher was the real subject of this experiment. When the learner's screams and pleadings reached a certain intensity, the teacher often asked whether he or she should continue, or might refuse to carry one. This was the crucial moment: the scientists now insisted that the session should continue.

Before the experiment began, psychologists predicted that only one in a thousand would administer the strongest shocks. In fact, during the first round of experiments, using Yale undergraduates, 60% were fully obedient and took the sessions to their conclusion. Subsequent experiments achieved similar results, with no significant differences between males and females.

(Note: I used August 7 as the starting point, as referenced in "The Man Who Shocked The World," linked below.)

Undated: ''The Manipulation of Human Behavior'

Funded in part by the U.S. government, this 1961 book summarizes various approaches to, as the editors put it, "the interrogation of an unwilling subject." From the introduction: "For this work, scientists who had done research in each of these areas were asked to review the state of relevant knowledge in their fields, to consider whether and how it might be applied by interrogators, and to evaluate the recourse available to highly motivated persons for resisting the attempted influence."

Undated: Ford Gyron

The two-wheeled concept car, built by the Ford Motor Co., makes the rounds of auto shows in 1961 (Detroit, New York), though as a nonrunning prototype; it was never meant to see the open road.

From a March 31 story by UPI: "It would have a gyroscope for stability and might be powered by fuel cells instead of a regular engine. ... The car will hold two people in contoured seats which support not only the head and back but the upper part of the legs as well. It has no steering wheel. Instead it uses a dial with separate rings for automatic speed and steering control. The car could be steered from either seat because the dial is located in a console between the seats and the car has dual accelerator and brake pads. A 10-button panel, also located in the console, supposedly would control a built-in computer to help a motorist of the future 'program' a trip on a non-stop expressway."
