  Falcon 9 is a partially reusable two-stage-to-orbit medium-lift launch vehicle designed and manufactured by SpaceX in the United States. Both the first and second stages are powered by SpaceX Merlin engines, using cryogenic liquid oxygen and rocket-grade kerosene as propellants The  Falcon 9  was intended to enable launches to Low-Earth orbit (LEO), Geosynchronous Transfer Orbit (GTO), as well as both crew and cargo vehicles to the International Space Station (ISS). Falcon 9 is a reusable, two-stage rocket designed and manufactured by SpaceX for the reliable and safe transport of people and payloads into Earth orbit and beyond. Falcon 9 is the world’s first orbital class reusable rocket. Reusability allows SpaceX to refly the most expensive parts of the rocket, which in turn drives down the cost of space access.

  The brain is the most complex and important organ in the human body. The brain is made of soft nervous tissues which control all body functions. It is the center of the nervous system in all invertebrates and vertebrates. It is located in the head and functions as the coordinating center of intellectual, sensation and the nervous system. So can we live without a brain? Well, let’s see if it’s possible or not. The brain is divided into two parts: the cerebrum and the cerebellum. The cerebrum controls important functions like our learning ability, emotion, etc. while on the other hand, the cerebellum controls activities such as balance and our muscle movements, etc. But the brain also determines our personality. There are several cases that show that a brain trauma can change someone’s personality. But back to our main question which is “Can we live without a brain?” To understand this, let us look at a case. In 2014, a 24 years old Chinese woman complained in a hospital about her ...

 what is Uranium use for ? Uranium “enriched” into U-235 concentrations can be used as fuel for nuclear power plants and the nuclear reactors that run naval ships and submarines. It also can be used in nuclear weapons. Depleted uranium (uranium containing mostly U-238) can be used for radiation shielding or as projectiles in armor-piercing weapons. Where does it comes from ? U-235 and U-238 occur naturally in nearly all rock, soil, and water. U-238 is the most abundant form in the environment. U-235 can be concentrated in a process called “enrichment,” making it suitable for use in nuclear reactors or weapons. What form is it in ? Uranium is an extremely heavy metal. Enriched uranium can be in the form of small pellets that are packaged in the long tubes used in nuclear reactors. What  if we ate Uranium ? Eating  large doses of  uranium  would be very dangerous;  if you  consumed 25 milligrams of it,  you 'd immediately start to experience kidney ...

  Mars  is a strange place and any humans  born  there are bound to look radically different. At some point, humans might settle  Mars . But according to an evolutionary biologist, babies  born  on the Red Planet will look, function, and behave dramatically different from Earthlings — and all within a few generations. If we ever manage to overcome the fertility and sex troubles of space , we'll probably be popping out little humanoid children on other planets. But our little tykes might not stay little for very long. On Earth we experience the steady hand of gravity at 1 g force constantly throughout our lifetimes. On other planets in our solar system, that's just not possible. Researchers are working on ways to make  artificial gravity is possible    in order to make long flights easier on human bodies. According to NASA, most astronauts grow about 2 inches while they're in space because the reduced gravity causes the fluid between...

  The number 3 serves as the only number that equals the sum  of  all preceding numbers (0 + 1 + 2 = 3). Also, when 3 is added to itself, the smallest perfect number ensues (6). And when 3 is squared, the result is the number that completes the single-digit numbers in the decimal system, better known as the number 9 why 369 is universe of key ? Nikola Tesla was obsessed with numbers, but especially 3, 6 and 9. He wanted the world to know the significance of the number 3 6 9, he claimed that these were extremely important numbers, but the question is why? What was that Nikola Tesla wanted the world to understand? How it became Nikola Tesla 3 6 9 theory? To understand that, we must first know about Mathematics. Why it is so different yet the same anywhere in the universe. Maths was and has been the most valued subject of all the time and the most powerful too. Two plus two will always be four everywhere in the universe. Possibly Nikola Tesla knew the power of the numbers 3 ...

  The Great Pyramid of Giza is the oldest and largest of the pyramids in the Giza pyramid complex bordering present-day Giza in Greater Cairo, Egypt. It is the oldest of the Seven Wonders of the Ancient World, and the only one to remain largely intact. Pyramids of Giza  | National Geographic. All three of  Giza's  famed  pyramids  and their elaborate burial complexes were  built  during a frenetic period of construction, from roughly 2550 to 2490 B.C. The  pyramids  were  built  by Pharaohs Khufu (tallest), Khafre (background), and Menkaure (front). The pharaoh's final resting place was usually within a subterranean burial chamber underneath the  pyramid . Although the  Great Pyramid  has subterranean chambers, they were never completed, and Khufu's sarcophagus rests in the King's Chamber, where Napoleon is said to have sojourned, deep  inside the Great Pyramid . The  Great Pyramid  at  Giza i...

  The Shimizu TRY 2004 Mega-City Pyramid is a proposed Shimizu Corporation project for the construction of a massive arcology-pyramid over Tokyo Bay in Japan. The structure would house 1,000,000 people.  The structure would be 2,004 meters (6,575 feet) high, including five stacked trusses  , each with similar dimensions to that of the great pyramid of Giza  . This pyramid would help answer Tokyo's increasing lack of space, although the project would only handle a small fraction of the population of the greater Tokyo area  ... The proposed structure is so large that it could not be built with current conventional materials, due to their weight. the construction of pyramid started in 2030 the floor area of pyramid is 8 squares kilometer .  Estimated completion  2110. The proposed structure is so large that it could not be built with current conventional materials, due to their weight. The design relies on the future availability of super-strong lightweig...
