Trigonometric Unit Circle and Graph Reference
The unit circle is a commonly used tool in trigonometry because it helps the user to remember the special angles and their trigonometric functions.
The unit circle is a circle drawn with its center at the origin of a graph(0,0), and with a radius of 1.
All angles are measured starting from the x-axis in quadrant one and may go around the unit circle any number of degrees.
Points on the outside of the circle that are in line with the terminal (ending) sides of the angles are very useful to know, as they give the trigonometric function of the angle through their coordinants. The format is (cos, sin).
Note that in trigonometry, an angle can be of any size, positive or negative. An angle larger than 360º means that you have gone round the circle more than once.
Chernobyl disaster
The Chernobyl disaster was a nuclear accident that occurred on 26 April 1986 at the No. 4 reactor in the Chernobyl Nuclear Power Plant, near the city of Pripyat in the north of the Ukrainian SSR in the Soviet Union. It is considered the worst nuclear disaster in history both in cost and casualties.

Is Chernobyl still radioactive?
Recently, engineers completed the construction of the New Safe Confinement (NSC). The NSC was supposed to stabilize the site, which is still highly radioactive and full of fissile material. … But the ensuing explosions launched radioactive fallout into the atmosphere across Europe.
Are animals in Chernobyl mutated?
According to a 2001 study in Biological Conservation, Chernobyl-caused genetic mutations in plants and animals increased by a factor of 20. Among breeding birds in the region, rare species suffered disproportional effects from the explosion’s radiation compared to common species.
What actually happened in the Chernobyl disaster?
The Chernobyl accident in 1986 was the result of a flawed reactor design that was operated with inadequately trained personnel. The resulting steam explosion and fires released at least 5% of the radioactive reactor core into the environment, with the deposition of radioactive materials in many parts of Europe.
Why isn’t nuclear power used more?
There are three key reasons for nuclear’s decline since the ’70s. Environmental groups, fearful of nuclear meltdowns and weapon proliferation, began lobbying governments to stop building new power plants. … The nuclear cleanup is expected to take 81 years to fully complete. Chernobyl put a moratorium on nuclear power.

All living creatures emit Light
Bioluminescence is the process of light emission in living organisms. Bioluminescence imaging utilizes native light emission from one of several organisms which bioluminesce.
The three main sources are the North American firefly, the sea pansy (and related marine organisms), and bacteria like Photorhabdus luminescens and Vibrio fischeri.
Now question arises, what human body emits light.
The answer is, Yes!
The human body literally glows, emitting a visible light in extremely small quantities at levels that rise and fall with the day, scientists now reveal. Past research has shown that the body emits visible light, 1,000 times less intense than the levels to which our naked eyes are sensitive.
Are humans actually bioluminescent?
According to a study conducted in 2009 by Japanese researchers, human bioluminescence in visible light exists – it’s just too dim for our weak eyes to pick up on. “The human body literally glimmers,” the team from the Tohoku Institute of Technology wrote in their study published in PLOS One.
What kind of light do humans emit?
visible light
Humans give off mostly infrared radiation, which is electromagnetic radiation with a frequency lower than visible light.
Are humans made of stardust?
Stars that go supernova are responsible for creating many of the elements of the periodic table, including those that make up the human body. ‘It is totally 100% true: nearly all the elements in the human body were made in a star and many have come through several supernovas.
Mount Yasur
Mount Yasur
Volcano in Vanuatu.
Mount Yasur is a volcano on Tanna Island, Vanuatu, 361 m high above sea level, on the coast near Sulphur Bay, northeast of the taller Mount Tukosmera, which was active in the Pleistocene. It has a largely unvegetated pyroclastic cone with a nearly circular summit crater 400 m in diameter.
Volcano type:
stratovolcano
Yasur is an active stratovolcano. It began erupting some time before 1774 (Captain Cook made the first report) and has be going every since. It has had, at times, a lava lake at a central vent. Some phreatic explosive eruptions have occurred.

Tanna Island, Vanuatu, -19.53°S / 169.44°E
Current status: erupting
Last update: 18 Jan 2022 (Smithsonian / USGS Weekly Volcanic Activity Report)
Mount Yasur is an easily accessible active volcano, and is a major Vanuatu tourist attraction.The Vanuatu Government monitors the level of volcanic activity in the interests of the public, both tourists and locals alike. This monitoring is carried out by the Vanuatu Geo-Hazards Observatory.
The importance of the volcano to Tanna’s tourism industry has resulted in the local government creating levels to alert people. These levels range from 0-5 and notes that An eruption may occur at any level.
Level 0 – Normal
Level 1 – Signs of Volcanic Unrest
Level 2 – Major Unrest
Level 3 – Minor Eruption
Level 4 – Moderate Eruption
Level 5 – Very Large Eruption
Is Mount Yasur still erupting?
It is a stratovolcano, caused by the eastward-moving Indo-Australian Plate being subducted under the westward-moving Pacific Plate. It has been erupting nearly continuously for several hundred years, although it can usually be approached safely.
How many times did Mount Yasur erupted?
The volcano has erupted many times per hour for at least 800 years. Yasur has been called the “Lighthouse of the Pacific” because of the regular Strombolian eruptions visible from sea.
Is Mount Yasur in the Ring of Fire?
World’s most active volcanoes.
Located in the southwest Pacific on Tanna Island in Vanuatu, Mount Yasur is part of the Pacific Ring of Fire, a string of volcanoes. … Because of the almost constant volcanic activity it is a popular tourist destination. Sometimes tourists are able to climb all the way to the summit.

Andrzej Żuławski
Polish film director
Description
Andrzej Żuławski was a Polish film director and writer. Żuławski often went against mainstream commercialism in his films, and enjoyed success mostly with European art-house audiences. In the late 1950s, he studied cinema in France.
Born: 22 November 1940, Ukraine
Died: 17 February 2016, Warsaw, Poland
Spouse: Małgorzata Braunek (m. 1971–1976)
Children: Vincent Żuławski, Xawery Żuławski, Ignacy Żuławski
Andrzej Żuławski’s ‘On the Silver Globe ‘ was filmed in 1976 and 1977 but only completed in 1987. It is a cult fantasy film recognised by the ‘Taste of Cinema’ website as the best non-Hollywood science fiction work in the history of cinema.
When the authorities unexpectedly allowed the film to be made, the artist returned to Poland after several years of forced emigration in France.
Żuławski maintained that On the Silver Globe was created under poor conditions. Despite this, the production was on a big scale and the film was shot on the beaches of Łeba, in Wieliczka salt mine, and the Gobi desert among other places. Although the budget did not allow for the use of special effects, costume and stage designers showed great inventiveness in creating a futuristic universe.
On the Silver Globe focuses on the theme of establishing a new civilisation. The film starts with a scene where two men find a record of an expedition to a foreign planet. The first part of the story presents a video diary made by the participants of the expedition and their descendants. In the recording, four astronauts arrive on the planet to create a new, better society in an environment resembling Earth. Stuck with each other, the isolated heroes quickly begin to doubt the mission and tensions and quarrels surface within the group.
On the Silver Globe:
Director: Andrzej Żuławski.
Screenplay: Andrzej Żuławski. Cinematography: Andrzej J. Jaroszewicz. Set design: Tadeusz Kosarewicz, Jerzy Śnieżawski.
Music: Andrzej Korzyński.
Starring: Andrzej Seweryn (Marek), Jerzy Trela (Jerzy), Grażyna Dyląg (Ihezal), Waldemar Kownacki (Jacek), Iwona Bielska (Marta), Jerzy Grałek (Piotr), Elżbieta Karkoszka (Ada), Krystyna Janda (Aza) and others.
Production: Pryzmat Film Group (1976-1978), Kadr Film Group (1986-1987), Poland 1987, colour, 157 minutes.
A space researcher Marek goes searching for a civilisation founded by space explorers on an unnamed Earth-like planet many years ago.
The astronauts give birth to a new civilisation, but, from generation to generation, the population becomes more and more savage. When, many years later, Marek (Andrzej Seweryn) arrives at the site, he sees people enslaved by Szerns – bird-like creatures native to the planet. Marek is given the role of a mythical saviour who will save the oppressed population. However, will he really give people freedom?
The plot is only a pretext for a philosophical discourse on the nature of man. In the director’s view, the history of civilisation on a foreign planet becomes a distorted reflection on the history of humanity on Earth.
There are many biblical themes in the film: the founding of the community resembles Genesis whereas Marek is clearly the equivalent of Jesus Christ. However, unlike in the Scripture, the divine is only a product of desperate people who create myths to soothe their existence. More than in deconstruction of religion, Żuławski is interested in the spiritual side of man. Are we able to overcome our animalistic nature and rise above the needs and desires of the flesh? It is precisely these doubts that continue to haunt Marek.
