India is Great, Indian people are also great:

If Sachin hits century then whole India will become happy. Indians are quite silent. If they start to think then nothing is impossible. This years Forbes magazine is highlighted Common Indian people, they got US patents, for their innovating products.Not the Ambani brothers, Mittal and Tata for his great invention to the market.

Mansukhbhai Jagani, Madanlal Kumawat, Mansukhbhai Patel, Chintakindi Mallesham and Mansukhbhai Prajapati are among Forbes's list of seven most powerful rural Indian entrepreneurs, whose "inventions are changing lives" of the people across the country.

IIM-Ahmedabad Professor and Founder of India's Honeybee Network, Anil Gupta, has selected the seven most powerful rural Indian entrepreneurs for a compilation in Forbes magazine.

"India's villages have become a hot bed of innovation, as its rural poor develop inventions out of necessity. Several of the people on this list have no more than an elementary school education," Gupta says.

Mansukhbhai Jagani developed a motorcycle-based tractor for India's poor farmers, which is both cost effective - costing roughly $318, and fuel efficient (it can plow an acre of land in 30 minutes with two liters of fuel).

After 4-5 years of experiments, Mansukhbhai developed an attachment for a motorbike -- a multi-purpose tool bar -- in 1994. This could be attached to any 325cc motorcycle by replacing the rear wheel with an assembly unit.

The 'super plough' called Bullet Santi (a cultivator that pulverizes or smoothens the soil is locally called as santi), can carry out various farming activities like furrow opening, sowing, inter-culturing and spraying operations.

A farmer, Mansukhbhai Patel invented a cotton stripping machine that has significantly cut the cost of cotton farming and revolutionized India's cotton industry.

Patel who studied up to Class X, invented a cotton-stripping machine in 1991.

Patel's machine helps in removing cotton from semi opened and unopened shells of various cotton varieties. The machine has won a U.S. patent.

Mansukhbhai Prajapati, a potter, invented a clay non-stick pan that costs 100 and a clay refrigerator that runs without electricity for those who cannot afford a fridge or their electricity and maintenance costs, Gupta said.

During the 2001 earthquake, all earthen pots were broken. "Some people told me the poor people's refrigerators are broken. They referred to the 'matkas'(pots) as refrigerators. It struck me then that I must try to make a fridge for those who cannot afford to buy a fridge," says Prajapati.

The patent winning Mitticool has been the most challenging product for him. It needed a lot of experimenting. He started work on it in 2001, the product was finally ready by 2004.

In 2005,he started the non-stick tava (pan) business. "My wife could not buy a non-stick tava as it was costly. So I thought many people would be facing the same problem. That's when I designed the non-stick tavas, priced between 50-100," he says.

Also on Gupta's list is Dadaji Ramaji Khobragade, who invented the HMT rice, a highly successful rice variety which yielded 80 percent more rice than the conventional variety.

HMT is now grown all over India, on 100,000 acres in five states.

Madanlal Kumawat, a grassroots innovator with no more than a fourth-grade education, developed a fuel-efficient, multi-crop thresher that yields cleaner grains, which can be bagged directly and eliminates the cost of cleaning.

The modified thresher reduces setup time to less than 15 minutes to switch over from one crop to another. Its latest variant can also handle groundnuts apart from threshing other cereals and pulses.

Anil Gupta said Chintakindi Mallesham, inventor of the Laxmi Asu Machine, "ignited a revolution in India's weaving community."

Mallesham's machine can make six saris worth of material in one day, and "no human effort is required beyond placing thread on the machine and removing the material after the process is complete."

Weavers making the traditional 'Tie & Dye' Poochampalli silk sarees used to undergo a painstaking process, moving their hands thousands of times in a day while weaving sarees. But not any more.

I thank to Prof: Gupta recognising the villagers.

Go India Go. Atleast In this way we are beating many. Inside us only many innovators are there, cowards are there. But keeping them aside I want to congratulate all the Village Innovators.

HOW CATS LAP

Again mystery of nature against science:

As we like cat as our favorite pet. But if you keep on observing cat, it will make you to think about science. Now the question is How cat laps milk means how fast it will drink the milk which is kept in bowl. As shown in figure below.


Animals have developed a range of drinking strategies depending on physiological and environmental constraints. Vertebrates with incomplete cheeks use their tongue to drink; the most common example is the lapping of cats and dogs. We show that the domestic cat (Felis catus) laps by a subtle mechanism based on water adhesion to the dorsal side of the tongue. A combined experimental and theoretical analysis reveals that Felis catus exploits fluidinertia to defeat gravity and pull liquid into the mouth. This competition between inertia and gravity sets the lapping frequency and yields a prediction for the dependence of frequency on animal mass. Measurements of lapping frequency across the family Felidae support this prediction, which suggests that the lapping mechanism is conserved among felines.


Frogs absorb water through their skin, desert lizards extract it from food, horses slurp it, and cats lap. Based on experimental and theoretical analyses, Reis et al. now show that cat lapping involves a subtle mechanism that exploits fluid inertia to defeat gravity. Cats curve their tongue backward so that the top surface touches the liquid surface and then raise their tongues rapidly, causing a liquid column to grow by inertia until gravity induces its breakage; closing their jaws captures the liquid. Experiments involving a water surface and glass disk reveal the lapping mechanism in greater detail.

Also what physics says regarding this problem, Newton thought of apple and invented Gravitational force. Same reis thought how the milk is breaking the gravitational field while cats lapping fluid inertia takes important role.Cats use fluid inertia to generate a liquid column that they catch in their mouths before gravity destroys it. If you dip glass plate in a water and remove water drop will come through with glass surface. In cat also happens this thing only.

People gave proof using maths for this problem.
