The Great Oxidation Event (GOE), sometimes also called the Great Oxygenation Event, Oxygen Catastrophe, Oxygen Crisis, Oxygen Holocaust, or Oxygen Revolution, was a time period when the Earth's atmosphere and the shallow ocean experienced a rise in oxygen, approximately 2.4 billion years ago (2.4 Ga) to 2.1–2.0 Ga during the Paleoproterozoic era. Geological, isotopic, and chemical evidence suggests that biologically induced molecular oxygen (dioxygen, O₂) started to accumulate in Earth's atmosphere and changed Earth's atmosphere from a weakly reducing atmosphere to an oxidizing atmosphere, causing almost all life on Earth to go extinct. The cyanobacteria producing the oxygen caused the event which enabled the subsequent development of multicellular forms.

"You Will" was an AT&T marketing campaign that launched in 1993, consisting of commercials directed by David Fincher. Each ad presented a futuristic scenario beginning with "Have you ever…" and ending with "…you will. And the company that will bring it to you: AT&T."

The ads were narrated by Tom Selleck.

The creative team that created the ad campaign at N.W. Ayer & Partners were Copy Supervisor Gordon Hasse, Art Supervisor Nick Scordato and Producer Gaston Braun.

One of the first web banner ads ever sold was part of an AT&T campaign that ran on HotWired starting October 27, 1994, asking "Have you ever clicked your mouse right HERE? You Will".

In 2016, technology writer Timothy B. Lee commented that "overall, the ads were remarkably accurate in predicting the cutting-edge technologies of the coming decades. But the ads were mostly wrong about one thing: the company that brought these technologies to the world was not AT&T. At least not on its own. AT&T does provide some of the infrastructure on which the world's communications flow. But the gadgets and software that brought these futuristic capabilities to consumers were created by a new generation of Silicon Valley companies that mostly didn't exist when these ads were made."

The ads won a few different awards at the time, notably the first annual David Ogilvy Award for the most effective campaign supported by research, the 1994 PCIA (Personal Communications Industry Award), and two ADDY Awards.

🔗 Astronomy 🔗 Time

Decimal time is the representation of the time of day using units which are decimally related. This term is often used specifically to refer to the French Republican calendar time system used in France from 1794 to 1800, during the French Revolution, which divided the day into 10 decimal hours, each decimal hour into 100 decimal minutes and each decimal minute into 100 decimal seconds (100000 decimal seconds per day), as opposed to the more familiar standard time, which divides the day into 24 hours, each hour into 60 minutes and each minute into 60 seconds (86400 SI seconds per day).

The main advantage of a decimal time system is that, since the base used to divide the time is the same as the one used to represent it, the representation of hours, minutes and seconds can be handled as a unified value. Therefore, it becomes simpler to interpret a timestamp and to perform conversions. For instance, 1^h23^m45^s is 1 decimal hour, 23 decimal minutes, and 45 decimal seconds, or 1.2345 decimal hours, or 123.45 decimal minutes or 12345 decimal seconds; 3 hours is 300 minutes or 30,000 seconds. This property also makes it straightforward to represent a timestamp as a fractional day, so that 2024-01-15.54321 can be interpreted as five decimal hours and 43 decimal minutes and 21 decimal seconds after the start of that day, or a fraction of 0.54321 (54.321%) through that day (which is shortly after traditional 13:00). It also adjusts well to digital time representation using epochs, in that the internal time representation can be used directly both for computation and for user-facing display.

🔗 Environment 🔗 Law 🔗 Backpacking

The freedom to roam, or "everyman's right", is the general public's right to access certain public or privately owned land, lakes, and rivers for recreation and exercise. The right is sometimes called the right of public access to the wilderness or the "right to roam".

In Scotland, Finland, Iceland, Norway, Sweden, Estonia, Latvia, Lithuania, Austria, Czech Republic and Switzerland, the freedom to roam takes the form of general public rights which are sometimes codified in law. The access is ancient in parts of Northern Europe and has been regarded as sufficiently basic that it was not formalised in law until modern times. However, the right usually does not include any substantial economic exploitation, such as hunting or logging, or disruptive activities, such as making fires and driving offroad vehicles.

In England and Wales public access rights apply only to certain categories of mainly uncultivated land.

Yuri Alekseyevich Gagarin  (9 March 1934 – 27 March 1968) was a Soviet Air Forces pilot and cosmonaut who became the first human to journey into outer space, achieving a major milestone in the Space Race; his capsule Vostok 1 completed one orbit of Earth on 12 April 1961. Gagarin became an international celebrity and was awarded many medals and titles, including Hero of the Soviet Union, his nation's highest honour.

Born in the village of Klushino near Gzhatsk (a town later renamed after him), in his youth Gagarin was a foundryman at a steel plant in Lyubertsy. He later joined the Soviet Air Forces as a pilot and was stationed at the Luostari Air Base, near the Norwegian border, before his selection for the Soviet space programme with five other cosmonauts. Following his spaceflight, Gagarin became deputy training director of the Cosmonaut Training Centre, which was later named after him. He was also elected as a deputy of the Soviet of the Union in 1962 and then to the Soviet of Nationalities, respectively the lower and upper chambers of the Supreme Soviet.

Vostok 1 was Gagarin's only spaceflight but he served as the backup crew to the Soyuz 1 mission, which ended in a fatal crash, killing his friend and fellow cosmonaut Vladimir Komarov. Fearing for his life, Soviet officials permanently banned Gagarin from further spaceflights. After completing training at the Zhukovsky Air Force Engineering Academy on 17 February 1968, he was allowed to fly regular aircraft. Gagarin died five weeks later when the MiG-15 training jet he was piloting with his flight instructor Vladimir Seryogin crashed near the town of Kirzhach.

The Wall of Sound (also called the Spector Sound) is a music production formula developed by American record producer Phil Spector at Gold Star Studios, in the 1960s, with assistance from engineer Larry Levine and the conglomerate of session musicians later known as "the Wrecking Crew". The intention was to exploit the possibilities of studio recording to create an unusually dense orchestral aesthetic that came across well through radios and jukeboxes of the era. Spector explained in 1964: "I was looking for a sound, a sound so strong that if the material was not the greatest, the sound would carry the record. It was a case of augmenting, augmenting. It all fit together like a jigsaw."

A popular misconception holds that the Wall of Sound was created simply through a maximum of noise and distortion, but the method was actually more nuanced. To attain the Wall of Sound, Spector's arrangements called for large ensembles (including some instruments not generally used for ensemble playing, such as electric and acoustic guitars), with multiple instruments doubling or tripling many of the parts to create a fuller, richer tone. For example, Spector often duplicated a part played by an acoustic piano with an electric piano and a harpsichord. Mixed well enough, the three instruments would then be indistinguishable to the listener.

Among other features of the sound, Spector incorporated an array of orchestral instruments (strings, woodwind, brass and percussion) not previously associated with youth-oriented pop music. Reverb from an echo chamber was also highlighted for additional texture. He characterized his methods as "a Wagnerian approach to rock & roll: little symphonies for the kids". The combination of large ensembles with reverberation effects also increased the average audio power in a way that resembles compression. By 1979, the use of compression had become common on the radio, marking the trend that led to the loudness war in the 1980s.

The intricacies of the technique were unprecedented in the field of sound production for popular music. According to Beach Boys leader Brian Wilson, who used the formula extensively: "In the '40s and '50s, arrangements were considered 'OK here, listen to that French horn' or 'listen to this string section now.' It was all a definite sound. There weren't combinations of sound and, with the advent of Phil Spector, we find sound combinations, which—scientifically speaking—is a brilliant aspect of sound production."
