List of some Indian inventions that may surprise you !!

  • Button - Buttons were made from seashell and were used in the Indus Valley Civilization (Now India and Pakistan ) for ornamental purposes by 2000 BCE. Buttons were carved into geometric shapes and had holes pierced into them so that they could be attached to clothing by using a thread.

  • Ruler - Rulers were made from Ivory and used by the Indus Valley Civilization in 1500 BCE. The  ruler was calibrated to about 1/16 of an inch which is less than 2 millimetres. The weights and measures of the Indus civilization also reached Persia and Central Asia, where they were further modified.
  • Stirrup - The earliest evidence of the stirrup was a toe loop that held the big toe and was used in India late in the second century BC. This ancient foot support consisted of a looped rope for the big toe which was at the bottom of a saddle made of fiber or leather.
  • Stepwell - The earliest stepwells most likely date to about 550 AD, but the most famous were built in medieval times. It is estimated that over 3,000 stepwells were built in the two northern states. Although many have fallen into disrepair, were silted in at some point in antiquity, or were filled in with trash in the modern era, hundreds of wells still exist. In New Delhi alone, there are more than 30.
  • Shampoo - The word shampoo in English is derived from Hindi word  "chāmpo" (चाँपो ). The shampoo itself originated in the eastern regions of the Mughal Empire that ruled erstwhile India, particularly in the Nawab of Bengal where it was introduced as a head massage, usually consisting of alkali, natural oils and fragrances. Shampoo was first introduced in Britain by a Bengali entrepreneur from Bihar named Sake Dean Mahomed.
  • Crescograph - It is a device for measuring growth in plants, was invented in the early 20th century by the Bengali scientist Sir Jagadish Chandra Bose.The Bose crescograph uses a series of clockwork gears and a smoked glass plate to record the movement of the tip of a plant (or its roots) at magnifications of up to 10,000.

  • Mysorean rockets - The first iron-cased and metal-cylinder rockets were developed by Tipu Sultan, ruler of the South Indian Kingdom of Mysore, and his father Hyder Ali, in the 1780s. They used them effectively against the British East India Company. Their conflicts with the company exposed the British to this technology, which was then used to advance European rocketry with the development of the Congreve rocket.

5 Innovative Inventions Of 2K14

Solar-panel windows

A breakthrough in quantum dot research by scientists at Los Alamos National Laboratory paved the way for windows that double as solar panels.Quantum dots - nano-crystals made of a semiconductor - were embedded in a transparent polymer in order to capture the sun's energy and harvest it as power.


Smart contact lenses

A smart contact lens that can monitor the glucose levels of diabetes sufferers was developed by Google in January.Coming out of the company's Google X skunk works division, best known for developing Google Glass, the contact lenses use chips and sensors the size of glitter to offer an early warning to the wearer by analysing tears.

SolePower 

Each thud of a hiker’s heel releases enough energy to illuminate a light bulb. Rather than waste that power, Matt Stanton, an engineer and avid backpacker, created a shoe insole that stores it as electricity.


XStat

To save more lives, a group of veterans, scientists, and engineers known as RevMedx has created a pocket-sized device called XStat : a faster, more effective way to plug wounds. The poly-carbonate syringe slides deep into a wound, such as a bullet track. When a user pushes down on the handle, it deposits dozens of pill-size sponges that expand to stem bleeding. Meanwhile, a substance in the sponges fights infection while clotting blood.

Smart expiry label

A London-based student developed a bio-reactive expiry label that decays at the same rate as food, potentially making a massive dent on the millions of tonnes of food wasted around the world each year.

Lazy Lifestyle Led To Weaker Bones

The comparatively light bone structure of modern humans compared to ancestor  and other modern primates may be due to the modern abandonment of the constant physical activity that was inherent in the life of early hunter gathers.

The most plausible explanation is that a lack of constant physical activity causes the bone in the head of the femur, the long bone in the thigh, to become thinner and lighter than that found in more mobile populations or modern primates such as chimpanzees, gorillas and orangutans.
The other two possible explanations, that humans and nonhuman primates have different bone structure because of genetics, with humans evolving to a lighter, more gracile structure, Or that the large joint surfaces required for upright, two-legged movement decrease the strain on bone and therefore the development of strong bones, do not appear to be true.

Ryan, working with Colin N. Shaw of the University of Cambridge, UK, looked at the hip joint to determine which of the three possible explanations was likely.

The researchers found that the agriculturalists had significantly lower bone mass than the foragers. However, the bone characteristics of the more mobile foragers overlapped with those of the nonhuman primates.

This knowledge might aid in prevention of osteoporosis and hip fracture in the elderly.

Antimicrobial Metal :- Copper !

Copper and its alloys (brasses, bronzes, copper-nickel-zinc, and others) are natural antimicrobial materials. Ancient civilizations exploited the antimicrobial properties of copper long before the concept of microbes became understood in the nineteenth century.

Bacteria, yeasts, and viruses are rapidly killed on metallic copper surfaces, and the term “contact killing” has been coined for this process. In several clinical studies, copper has been evaluated for use on touch surfaces, such as door handles, bathroom fixtures, or bed rails, in attempts to curb nosocomial infections. In connection to these new applications of copper, it is important to understand the mechanism of contact killing since it may bear on central issues, such as the possibility of the emergence and spread of resistant organisms, cleaning procedures, and questions of material and object engineering. Recent work has shed light on mechanistic aspects of contact killing.
The antimicrobial properties of copper are still under active investigation. Molecular mechanisms responsible for the antibacterial action of copper have been a subject of intensive research. Scientists are also actively demonstrating the intrinsic efficacies of copper alloy "touch surfaces" to destroy a wide range of microorganisms that threaten public health.
 In addition, different copper alloys should be tested not only for their effectiveness but also for their esthetic appeal. Finally, the antimicrobial properties of copper surfaces must be integrated with other methods of disinfection and the overall hygiene concept of a health care facility. Additional measures, such as the addition of spore germinants to cleaning solutions to improve killing of spores, also deserve further investigation.

Mission :- Educated Bharat


As we know that in Bharat there a lot of children who never get any education. This is because of their background, caste and other problems. I want to education all of them which is impossible yet, but i have an idea to educate them.
In Bharat there are a lot of families and a family has a housewife. I know that most them are not educated, but 50% of them are educated. From this 50%, 25% are working or employed anywhere, but 25% are free. So, when they have their spare time (generally afternoon), they should collect 2 or 3 children (who don't have money to educate them) and educate them, just for 1 hour daily. If one housewife educate 3 children, then 5 million housewife educate 15 million of children every hour in India. And in this 15 million of children 50% are girls, so the housewives of Bharaeducating girls too. 
At last, it is my request to all the reader please give you 1% percent by sharing my view, because your 1% will be 10% of Bharat's Future .
Thank You for reading , i hope you co-operate .

Does Curiosity Improve Your Brain Memory ?

As everyone knows it's easier to learn about a topic you're curious about.Now, a new study reveals what's going on in the brain during that process, revealing that such curiosity may give a person a memory boost.
When participants in the study were feeling curious, they were better at remembering information even about unrelated topics, and brain scans showed activity in areas linked to reward and memory.
The results, detailed Oct. 2 in the journal Neuron, hint at ways to improve learning and memory in both healthy people and those with neurological disorders, the researchers said.
Not surprisingly, the study researchers found that people remembered more information about the trivia when they were curious about the trivia answers.But unexpectedly, when the participants were curious, they were also better at remembering the faces, an entirely unrelated task. 
Participants who were curious were also more likely than others to remember both the trivia information and unrelated faces a day later, the researchers found.

The brain scans showed that, compared with when their curiosity wasn't piqued, when people were curious, they showed more activation of brain circuits in the nucleus accumbens, an area involved in reward. These same circuits, mediated by the neurochemical messenger dopamine, are involved in forms of external motivation, such as food, sex or drug addiction.

Finally, being curious while learning seemed to produce a spike of activity in the hippocampus, an area involved in forming new memories, and strengthened the link between memory and reward brain circuits.

According to my view being curious is very important because of that we can discover, invent, improve and know about  everything . 
So, 
                                                     Be curious, not judgemental.
