Appreciate Talent : Arina Pozdnyak : Perpetual Calendar













We place too much value into something as elusive as time. This is the lesson that Arina Pozdnyak, the creator of Perpetual Calendar, is trying to teach us. Days fly by, and even months are mere speckles of sand in an hourglass of eternity. People do not realize that the time given to us by fate cannot be measured using months or even years. It is measured using emotions and impressions. If a person lives to be 150 years old without experiencing any emotions, he might as well have lived one day, for all it’s worth. On the other hand, a person who lived an exciting, fulfilling life, read countless books and cherished every moment that he had, is actually the one who lived a longer life, even if in reality his flame was snuffed out much too soon.

Eco-Preservation : Water Pollution in China : Gallery

pollution china

Growing cities, overuse of fertilizers and factory wastewater have degraded China’s water supplies to the extent that half the nation’s rivers and lakes are severely polluted. China aims to spend $850 billion to improve filthy water supplies over the next decade, but even such huge outlays may do little to reverse damage caused by decades of pollution and overuse in Beijing’s push for rapid economic growth.

Know : What Colour is Lava? Blue!

Yes! This volcano in Kawah Ijen has some spectacular blue lava by night, but shows red during the day.

It is the sulfur inside the volcano that causes the change in color. What turns the waters of the largest acidic crater lake in the world, gives its beautiful turquoise color. The same acidic gases burns a bright blue color when ignited by miners while condensation turns it into liquid sulfur which mimics flowing blue lava. Condensation of molten sulfur also drives the business of a sulfur mining operation on Kawah Ijen.

Documentary: Did We Land on the Moon?

The Moon landing conspiracy theories claim that some or all elements of the Apollo program and the associated Moon landings were hoaxes staged by NASA with the aid of other organizations. The most notable claim is that the six manned landings (1969–1972) were faked and that twelve Apollo astronauts did not actually walk on the Moon. Various groups and individuals have made such conspiracy claims since the mid-1970s. Conspiracy theorists (henceforth conspiracists) claim that NASA and others knowingly misled the public into believing the landings happened, by manufacturing, tampering with, or destroying evidence including photos, telemetry tapes, radio and TV transmissions, Moon rock samples, and even some key witnesses.

Much third-party evidence for the landings exists, and detailed rebuttals to the hoax claims have been made. Since the late 2000s, high-definition photos taken by the Lunar Reconnaissance Orbiter (LRO) of the Apollo landing sites have captured the lander modules and the tracks left by the astronauts. In 2012, images were released showing the Apollo missions’ American flags still standing on the Moon.

Conspiracists have managed to sustain public interest in their theories for more than 40 years, despite the rebuttals and third-party evidence. Polls taken in various locations have shown that between 6% and 20% of Americans surveyed believe that the manned landings were faked, rising to 28% in Russia. Even as late as 2001, the major television network Fox broadcast a documentary named Conspiracy Theory: Did We Land on the Moon? claiming NASA faked the first landing in 1969 to win the Space Race.

Know : 100s of Rose Species (Gallery)

rose is a woody perennial of the genus Rosa (The name rose comes from French, itself from Latin rosa), within the family Rosaceae. There are over 100 species. They form a group of plants that can be erect shrubs, climbing or trailing with stems that are often armed with sharp prickles. Flowers vary in size and shape and are usually large and showy, in colours ranging from white through yellows and reds. Most species are native to Asia, with smaller numbers native to Europe, North America, and northwest Africa. Species, cultivars and hybrids are all widely grown for their beauty and often are fragrant. Rose plants range in size from compact, miniature roses, to climbers that can reach 7 meters in height. Different species hybridize easily, and this has been used in the development of the wide range of garden roses.

The Gallery here features native Roses (Rosa flowers not the hybrid ones, which we will post later)

The genus Rosa is subdivided into four subgenera:

  • Hulthemia (formerly Simplicifoliae, meaning “with single leaves”) containing one or two species from southwest AsiaR. persica and R. berberifolia (syn. R. persica var. berberifolia) which are the only roses without compound leaves or stipules.
  • Hesperrhodos (from the Greek for “western rose”) has two species, both from southwestern North America. These are R. minutifolia and R. stellata.
  • Platyrhodon (from the Greek for “flaky rose”, referring to flaky bark) with one species from east Asia, R. roxburghii.
  • Rosa (the type subgenus) containing all the other roses. This subgenus is subdivided into 11 sections.
    • Banksianae – white and yellow roses from China
    • Bracteatae – three species, two from China and one from India
    • Caninae – pink and white species from AsiaEurope and North Africa
    • Carolinae – white, pink, and bright pink species all from North America
    • Chinensis – white, pink, yellow, red and mixed-color roses from China and Burma
    • Gallicanae – pink to crimson and striped roses from western Asia and Europe
    • Gymnocarpae – a small group distinguished by a deciduous receptacle on the hip; one species in western North America (R. gymnocarpa), the others in east Asia
    • Laevigatae – a single white species from China
    • Pimpinellifoliae – white, pink, bright yellow, mauve and striped roses from Asia and Europe
    • Rosa (syn. sect. Cinnamomeae) – white, pink, lilac, mulberry and red roses from everywhere but North Africa
    • Synstylae – white, pink, and crimson roses from all areas
