These 15 Dogs Were Sent to Space By Soviet Union

Before Yuri Gagarin became the first human in space, dozens of ordinary stray dogs boldly went where no living thing had gone before. The luckiest of these canine cosmonauts returned home to be adopted, or to become mothers and fathers. Far too many perished, and most were forgotten. Here, we honor 15 of the star dogs that involuntarily helped launch humanity into the space age.

6 Facts About The Asteroid Which Destroyed The Dinosaurs

About 66 million years ago, there was a last perfect day for the dinosaurs. Then, a piece of the sky fell to Earth – forever changing the planet’s evolutionary complexion, and ultimately creating the world we know today. Here, we’ve broken down the details of that fateful day. 1. Impact Site A crater buried beneath the Yucatan Peninsula in Mexico more than 180 kilometres (100 miles) in diameter and 20 km (12 mi) in depth. 2. Prehistoric Time Textiles only form during asteroid impact and high yield nuclear detonation. Samples from the impact site were determined to be 66,038,000 ± 11,000 years old – around the time between the Cretaceous and Paleogene periods. 3. Impactor An asteroid or comet with a diameter of 10 km (6.2 mi) or larger, which was travelling at speeds of 16 to 32 km/sec (10 to 20 miles/sec) when it hit Earth. 4. Impact specifics Energy Yield: The explosion energy of the impact is estimated to have been 420 zettajoules (over a billion times the energy of the atomic bombings …

How Television Evolved: The Story of 22 Generations

Television will get the biggest share of credit for the evolution of humans to modern times. We know the world we live in is mostly through the television. But, the history of television and story of its evolution is The television has been a staple of the global living room since the 1930s. Back then, TV sets were bulky, and screens were tiny-a black and white unit with a resolution of 8X8 pixels was widely considered the lap of luxury. Today’s television sets seem to be growing thinner and more detailed by the minute. It may not be long before they disappear altogether, perhaps, replaced by virtual reality screening rooms, or micro projectors embedded in our watches. But the TV sets will live on in memory. Take a peek at some of the most technologically notable units from the history of television. 1928 Octagon General Electric’s octagon is largely considered the first working television, although it never became commercially available. The set used a rotating disc and a neon lamp to produce images on a 3-inch …

9 Worst Nuclear Disasters In The History According to INES

We rounded up some of the world’s worst nuclear disasters ranked by their placement on the International Nuclear and Radiological Event Scale (INES). 1. SL-1 Experimental Power Station Idaho, USA 3 January 1961 This nuclear disaster was caused by improper removal of control rod responsible for absorbing neutrons in the reactor core, resulting in a steam explosion and meltdown. The accident killed three operators while 22 other workers were fully exposed to the radiation.  790 other people exposed to harmful levels  during cleanup and disposal of radioactive wastes. $4.3 million worth of property loss was estimated from the incident. 2. RA-2 Facility Buenos Aires, Argentina 23 September 1983 This nuclear accident was caused due to operator error while re-configuring a fuel plate. leading to a nuclear reactor assembly meltdown. nuclear accident the operator died 2 days later after exposure to massive doses of gamma and neutron rays. 17 others in the facility absorbed radiation doses. 3. Tokaimura Nuclear Accident 30 September 1999 Tōkai, Japan This need a disaster occurred when workout at the nuclear power plant …

Animals That Went Extinct In The 21st Century

Bermuda Saw-Whet Owl Native To: Bermuda Disappeared: 2014 Reason: Unknown, but may be due to the decline of cedar and palmetto trees, or the arrival of non-native predators and competitors. Formosan Clouded Leopard Native To: Taiwan Disappeared: 2013 Reason: Extensive logging of natural habitat. Cape Verde Giant Skink Native To: Cape Verde Islands Disappeared: 2013 Reason: Hunted for food and “skink oil” by native Pinta Island Tortoise Native To: Pinta Island, Ecuador Disappeared: 2012 Reason: Hunting Japanese River Otter Native To: Seto Inland Seas, Uwa Sea Disappeared: 2012 Reason: Hunting in the past, pollution and human development during recent times. Western Black Rhinoceros Native To: Sub-Saharan Africa Disappeared: 2011 Reason: Poaching Eastern Cougar Native To: northeastern North America Disappeared: 2011 Reason: Hunting, and decline of its primary prey, the white tailed deer, also due to hunting.

Supercomputers of Each Generation (History of Supercomputers)

To appreciate the scale of a supercomputer, you must understand how its performance is measured. We measured them in FLOPS, which stands for floating – point operations per second. Floating-point encoding allows for very long numbers to be handed with ease, and is useful in a number of scientific fields. 1. (CDC 6600) 1964 Processing power: 3 million FLOPS The CDC 6600 was designed by Seymour cray, the father of supercomputing, and is widely considered the world’s first supercomputer. It  would be the fastest computer in the world for five years until it was replaced by the CDC 7600. 2. CRAY – 1 1976 processing power: 80 million FLOPS The Cray – 1 was designed and manufactured by Cray Research, and came to be one of the most popular and successful supercomputers in history. It was the first supercomputer to fully exploit vector processing. 3. CRAY X – MP 1982 Processing Power: 400 million FLOPS The CRAY X – MP was the successor of the Cray – 1, and was also built by Cray Research. …

Top 5 Mass Extinctions of Earth’s History We Know About

1. The Ordovician-Silurian Extinction 439 million years ago Didn’t ordovician period, most life on earth lived in the sea. A sudden drop in sea levels occurred as glaciers formed, and a sudden rise in sea levels are god is glaciers melted. This dramatically impacted sea dwelling creatures, causing about 25% of marine families and 60% of marine genera to die. The Late Devonian Extinction 364 million years ago During this extinction event much of the sea but became the word of oxygen, making it inhospitable for anything except bacteria. Scientist think that new plant species caused the climate change, with significantly contributed to the massive loss of life. Notably the event may have been characterized by series of extensions over several million years, rather than a single event. Three quarters of a species died. The Permian Triassic Extinction 215 million years ago The permian mass extinction has been nicknamed “The Great Dying” since a staggering Instagram 96% of species disappear. This means that all life on Earth is descended from the 4% of species that survive. Although direct evidence has yet …

10 Deadliest WW-II Weapons Made By Germany

Our teachers, elders, and books introduced Hitler to us as the greatest dictator of all times. He was inspired with his obsession of winning the world and he knew that his dream may only come true if his army had unanswerable weapons. So he appointed the best scientists of that time to develop some unmatched war equipment and highly advanced deadly weapons that would engineer the structure of his motive. Some of the dream weapons of the Nazis became reality, some remained unsuccessful, and some would have remained unknown to the world, buried with their plans. A few weapons came to be known to the world later which we’ll talk about here. These weapons were meant to bow the Zeniths of all the earth into the feet of this furious dictator. These weapons could have turned any war into his favor. So are you in the mood to go back to the fearful time of Hitler and know about his deadly plans? 1. Schwerer Gustav This monstrous canon, also known as ‘The Great Gustav’ is the largest canon build yet. It was …
