Wikipedia Picture of the Day - March 30th, 2021 - Vincent van Gogh (Narrated by Salli)
Vincent van Gogh (30 March 1853 – 29 July 1890) was a Dutch Post-Impressionist painter and one of the most famous and influential figures in the history of Western art. In just over a decade, he created about 2,100 artworks, including around 860 oil paintings, most of which date from the last two years of his life. Van Gogh sold few paintings during his lifetime, and was contemporaneously considered a madman and a failure. However, he has attained widespread critical and popular acclaim since the early 20th century, and his works are among the world's most expensive paintings. Van Gogh produced this oil-on-canvas self-portrait in September 1889. One of his several self-portraits, it may have been his last, produced shortly before he left Saint-Rémy-de-Provence in southern France. The work is now in the collection of the Musée d'Orsay in Paris.
Wikipedia Picture of the Day - February 21st, 2023 - Robert le diable (Narrated by Salli)
Robert le diable is an opera in five acts composed by Giacomo Meyerbeer between 1827 and 1831, to a libretto written by Eugène Scribe and Germain Delavigne. Superficially based on the medieval legend of Robert the Devil, it is regarded as one of the first French grand operas. This illustration depicts the set design by Pierre-Luc-Charles Cicéri of the opera's third act, known as the Ballet of the Nuns.

Wikipedia Picture of the Day - August 20th, 2023 - Viscosity (Narrated by Emma)
The viscosity of a fluid is a measure of its resistance to deformation at a given rate. The SI unit of viscosity is the pascal-second. For liquids, it corresponds to the informal concept of "thickness": for example, syrup has a higher viscosity than water. Viscosity quantifies the internal frictional force between adjacent layers of fluid that are in relative motion. For instance, when a viscous fluid is forced through a tube, it flows more quickly near the tube's axis than near its walls. This fluid animation shows a simulation of two fluids with different viscosities being poured into identical containers. The blue liquid on the left has a lower viscosity than the orange liquid on the right.

Wikipedia Picture of the Day - January 16th, 2024 - Lightning (Narrated by Salli)
Lightning is a natural phenomenon formed by electrostatic discharges through the atmosphere between two electrically charged regions, either both in the atmosphere or one in the atmosphere and one on the ground, temporarily neutralizing these in a near-instantaneous release of an average of between 200 megajoules and 7 gigajoules of energy, depending on the type. The three main types of lightning are distinguished by where they occur: either inside a single thundercloud (intra-cloud), between two clouds (cloud-to-cloud), or between a cloud and the ground (cloud-to-ground), in which case it is referred to as a lightning strike. Lightning causes thunder, a sound from the shock wave which develops as gases in the vicinity of the discharge heat suddenly to very high temperatures. It is often heard a few seconds after the lightning itself. Thunder is heard as a rolling, gradually dissipating rumble because the sound from different portions of a long stroke arrives at slightly different times. This photograph shows strokes of cloud-to-ground lightning hitting the Mediterranean Sea close to Port-la-Nouvelle in southern France.

Wikipedia Picture of the Day - April 26th, 2020 - Nototropis falcatus (Narrated by Emma)
Nototropis falcatus is a species of amphipod crustacean found in the northeastern Atlantic Ocean and North Sea, where it lives on the seabed. Growing to a length of about 7 mm (0.3 in), the third pereiopod or thoracic leg is particularly stout, and has a curved propodus (penultimate joint) and a powerful dactylus (claw). It can swim using its abdominal legs and orienting itself on its side, and can also burrow in the soft substrate. The species probably feeds by grazing on plant material and consuming detritus.
This picture shows an N. falcatus individual collected at a dredge disposal site off Zeebrugge, Belgium.

Beautiful News Daily - March 16th, 2020 - The Humpback Whale Is Recovering (Narrated by Salli)
This precious whale was brought to the edge of extinction. Campaigns to save them began in the 1970s. They were placed on endangered species lists. Commercial whaling was banned. This gave them space to recover.
Numbers have climbed ever since. In some parts of the world they’re flourishing. It’s a huge ecological success.

Astronomy Picture of the Day - September 8th, 2022 - North America and the Pelican (Narrated by Joanna)
Fans of our fair planet might recognize the outlines of these cosmic clouds. On the left, bright emission outlined by dark, obscuring dust lanes seems to trace a continental shape, lending the popular name North America Nebula to the emission region cataloged as NGC 7000. To the right, just off the North America Nebula's east coast, is IC 5070, whose avian profile suggests the Pelican Nebula. The two bright nebulae are about 1,500 light-years away, part of the same large and complex star forming region, almost as nearby as the better-known Orion Nebula. At that distance, the 3 degree wide field of view would span 80 light-years. This careful cosmic portrait uses narrowband images combined to highlight the bright ionization fronts and the characteristic glow from atomic hydrogen, and oxygen gas. These nebulae can be seen with binoculars from a dark location. Look northeast of bright star Deneb in Cygnus the Swan, soaring high in the northern summer night sky.

Wikipedia Picture of the Day - July 11th, 2021 - Emily J. Harding (Narrated by Emma)
Emily J. Harding (1850–1940) was a British artist, illustrator and suffragette, and a member of the Artists' Suffrage League. This poster, created by Harding around 1907 to 1918 in support of the suffrage movement in the United Kingdom, depicts a woman wearing an academic cap and gown standing inside a locked gate with a "convict" and a "lunatic", to illustrate the fact that none of the three had a vote for Parliament.

Wikipedia Picture of the Day - December 13th, 2023 - Bézier curve (Narrated by Matthew)
A Bézier curve is a parametric curve used in computer graphics and related fields. Related to the Bernstein polynomial, it is named after Pierre Bézier, who used it in the 1960s for designing curves for the bodywork of Renault cars. Other uses include the design of computer fonts and animation. Bézier curves can be combined to form a Bézier spline, or generalized to higher dimensions to form Bézier surfaces. This animation shows a linear Bézier curve, the simplest type, generating a straight line between the points P0 and P1. This is equivalent to linear interpolation.

Wikipedia Picture of the Day - December 8th, 2023 - Mount Api (Narrated by Brian)
Mount Api is a limestone mountain located in Gunung Mulu National Park in Sarawak, Malaysia. It is part of the same formation as Mount Benarat and Mount Buda. Mount Api is notable for its striking limestone karst formations, commonly known as "the pinnacles". The mountain hosts many caves, with passages linking to the massive Clearwater Cave system. It features a great diversity of pitcher plants, with at least eight different species recorded on the mountain. This 2019 photograph shows the karst pinnacles near the peak of Mount Api.
