Tanko Science: Combination of all things related to this universe regarding science world and education world.
Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about theuniverse. In an older and closely related meaning, "science" also refers to this body of knowledge itself, of the type that can be rationally explained and reliably applied.
Contemporary science is typically subdivided into the natural sciences which study the material world, the social sciences which study people and societies, and the formal sciences like mathematics. The formal sciences are often excluded as they do not depend onempirical observations.Disciplines which use science like engineering and medicine may also be considered to be applied sciences.[4]
From classical antiquity through the 19th century, science as a type of knowledge was more closely linked to philosophy than it is now. In fact, in the West during the early modern period the terms "science" and "natural philosophy" were sometimes used interchangeably to refer to the study of natural phenomena.
In the 17th and 18th centuries scientists increasingly sought to formulate knowledge in terms of laws of nature. Over the course of the 19th century, the word "science" became increasingly associated with the scientific method itself, as a disciplined way to study the natural world, including physics, chemistry, geology and biology. It is in the 19th century also that the term scientist began to be applied to those who sought knowledge and understanding of nature.
Science in a broad sense existed before the modern era, and in many historical civilizations. Modern science is distinct in its approachand successful in its results: 'modern science' now defines what science is in the strictest sense of the term.
Science in its original sense is a word for a type of knowledge, rather than a specialized word for the pursuit of such knowledge. In particular it is one of the types of knowledge which people can communicate to each other and share. For example, knowledge about the working of natural things was gathered long before recorded history and led to the development of complex abstract thinking. This is shown by the construction of complex calendars, techniques for making poisonous plants edible, and buildings such as the pyramids. However no consistent conscientious distinction was made between knowledge of such things which are true in every community and other types of communal knowledge, such as mythologies and legal systems.
JELLYFISH EVAPORATE IN THE SUN. THEY'RE 98% WATER!
Jellyfish are between 94 and 98 percent water, and when exposed fully to the sun, such as beaching themselves, they will evaporate, almost completely within a few hours. When jellyfish are in the water, they can be a bit intimidating. Their tentacles can pack a painful electrical shock. However, once they wash up on shore, they are anything but intimidating.
Jellyfish are about 98 percent water. If a jellyfish washes up on the beach, it will mostly disappear as the water evaporates.
It turns out that jellyfish are 98% water. Most are transparent and bell-shaped. If they end up on the beach, they will most likely evaporate in a few hours and mostly disappear.
What about their bones and organs? Jellyfish also don’t have brains, bones or a heart. They do have rudimentary sensory nerves though. They react directly on food and danger stimuli via nerve impulses without having any brain to process the impulses.
A species of jellyfish, the Box jellyfish (sea wasp) kills more people than any other marine creature each year.

World’s first telescopic contact lens gives you Superman-like vision
An international team of researchers have created the first telescopic contact lens; a contact lens that, when it’s equipped, gives you the power to zoom your vision almost three times. Yes, this is the first ever example of a bionic eye that effectively gives you Superman-like eagle-eye vision.
As you can see in the photo above, the telescopic contact lens has two very distinct regions. The center of the lens allows light to pass straight through, providing normal vision. The outside edge, however, acts as a telescope capable of magnifying your sight by 2.8x. This is about the same as looking through a 100mm lens on a DSLR. For comparison, a pair of bird-watching binoculars might have a magnification of 15x. The examples shown in the image below give you a good idea of what a 2.8x optical zoom would look like in real life.
