Canadian James Hobson, known as "Hacksmith," has 10 million users and is dedicated to bringing science fiction to life.

The observable Universe. Do not you think its impressive? This is an illustrated logarithmic scale conception of the observable Universe with the Solar System at the center. Surrounding the Solar System are the inner and outer planets, the Kuiper belt, the Oort cloud, the Alpha Centauri star, the Arm of Perseus, the Milky Way, the Andromeda galaxy, the cosmic network, cosmic microwave radiation, and the Invisible plasma produced by the Big Bang. The image was created by the musician and artist Pablo Carlos Budassi , the image is massed in the logarithmic maps of the Universe made by researchers from Princeton University , as well as images produced by NASA based on observations made by their telescopes and space probes. Princeton's team, led by astronomers J. Richard Gott and Mario Juric, based their logarithmic map on data from the Sloan Digital Sky Survey , which for the past 15 years has used a telescope at the Apache Point Observatory, to create the most detailed

Bobby Shafan, David Kellman and Eddy Galland. Discover the incredible story of Bobby Shafan, David Kellman and Eddy Galland. If you think you are seeing triple, you are not wrong.

The history of timekeeping culminates in the invention of the mechanical clock . It was not until the 14th century that people begun to measure time in smaller units. Until then, humans relied on nature to determine the time of the day. In the 6th century, a demand for more accurate time measurement arose in the medieval monasteries of Europe. The monks followed the ancient Greeks and Romans who originally divided the day into 12 hours, and divided each day and each night into twelve equal units - hours. To determine the time of the day, the monks used a variety of timekeeping devices. Historians are unable to determine when exactly the first mechanical clock was invented, but according to researchers the earliest mechanical clocks originated in Europe, at the beginning of the Late Middle A

Have you ever wondered how dolphins and other marine mammals obtain fresh water when they have been in salty environments all their lives?  These Wild animals Are Surrounded by Water. But What Do They Drink?  They don't have a desalination unit like in the gills of marine fish, and their kidneys can't dissolve sedimentary minerals. What kind of trick did nature invent? They can't drink seawater : w ith dolphins and whales, nature played an evil joke. It would seem that they are surrounded by water, but the use of salt water, on the contrary, will lead to dehydration and death. In the case of sea fish, part of the salt that comes with sea water into the body is desalinated in the gills, and the salty surpluses come out with urine. The salty environment in which they live, constantly pulls moisture out of the fish through the skin. It's a natural process - osmosis .   Therefore, these sea creatures have to drink sea water all the time and th
