‘I always want to master whatever people call impossible’

A relaxed Michael Phelps looked at the Times Sport page, saw the previous night’s IPL report, and chuckled. “Cricket? Doesn’t that take, like, 10 days to get over?”
He was only joking, of course, but we explained there were three formats, and that this was the ultra-shortened version. He seemed to like the idea, especially an analogy which cropped up about fine wine co-existing with the cheaper variety on the shelves, but still couldn’t stop guffawing about a game taking days to get over!

Phelps’ swimming career, after all, was all about short, sharp bursts of sustained physical, tactical and technical excellence. It was all about extending the will and soaring above the bounds of the possible, something he did better, and more often, than most other sportspersons in history.

The most decorated Olympian of all time, with 28 medals, 23 of them gold, Phelps is that rarest of rare species — a sporting genius. As we found out, though, he can also be remarkably human. Here as brand ambassador for apparel company Under Armour, Phelps is still easing into his various post-career roles, and still staving off the keen urge to compete. Most importantly, Phelps the superstar is learning to coexist with Michael the ordinary family man.

AICTE to introduce students feedback-based assessment for the promotion of Engineering teachers

Besides research work and their overall performance, teachers in Engineering colleges will now be appraised on the basis of students' evaluation All India Council of Technical Education's (AICTE) decision to include the students' feedback to assess the teachers has been introduced to improve the educational quality of engineering colleges. But, its effectiveness remains to be seen. "Since students' feedback will be considered while granting promotion to the teachers, they will have to put their best foot forward in the classroom. This assessment pattern is followed by the IITs and NITs," says AICTE chairman Anil Sahasrabudhe.

As per the rule, students' feedback will have 25% weightage in the overall assessment of the faculty, which will be a decisive component for their promotions. Till now, the focus for promoting teachers in colleges has been on the number of research papers published by the faculty members. This was partly the reason for the publication of substandard research papers in fake journals. "Colleges in tier II and III cities, may not have the resources to conduct research. But research publications being given high priority during promotions often leads to the problem of paid journals. The new assessment will thus award good teachers," adds Sahasrabudhe. While some academicians are positive about the impact of this assessment system, others are of the view that students might not be honest with their feedbacks owing to various reasons. "Students are sometimes not objective or may be simply confused while giving feedback for teachers. Their opinions are based on peer thinking. While interacting with the students, I have come across several students who behave differently in class and during one-on-one interactions," says Govinda K, professor, School of Computer Science and Engineering, Vellore Institute of Technology (VIT). Addressing the concern, Sahasrabudhe says that the number of such students is mostly low, thus the overall score of a teacher who is good at his work is not hampered. "Some students may give poor feedback, probably because the teacher is strict or is not lenient with marks, but this is temporary. In the long run, a teacher who is passionate about teaching and thinks about students' welfare will always be valued by the majority. Also, such an assessment will also ensure better student-teacher communication," he says. This system will allow the teachers to address their weaknesses and improve teaching methods, says KK Mahapatra, dean, Academics at NIT, Rourkela. "Since students are the direct beneficiaries, this will help the teachers to analyse their skills, for instance, maybe there is an issue with communication or students might be finding the teaching method complicated," says Mahapatra.

Niranjan Karagi’s Nirnal world’s cheapest portable water filter

Sometimes, the inspiration for the most brilliant of inventions can come from the most humbling of places. Such is the case for NirNal founder Niranjan Karagi while he was playing in a schoolyard nearby his home has invented and patented the world’s cheapest water filter which costs Rs.30 and can be used for 100 times and fits any water bottle and this removes 99% of bacteria and other disease-causing water contaminants.

AAB is proud that we were the first ones to cover his project in December 2016, An Engineer Filters the Way to Success.
Niranjan now has many accolades to his name including Best Entrepreneur Award by Deshpande Foundation – Feb 2017, Best Entrepreneur Award by Visvesvaraya Technological University (VTU) – Jan 2017, Yuva Shilpi Award by Akhil Bharatiya Vidyarthi Parishad (ABVP).
It is a compatible, portable, reusable, healthy and an eco-friendly water purifier. A product that ensures ‘Safe Drinking water ’ at an affordable price. This acts as a filter when the water oozes out of Nirnal fixed to the bottles. It is easy to use, imparts taste and also adds some essential minerals to the water. It uses activated charcoal, Filter cloth.

Niranjan did his schooling from St. Mary’s school Belagavi and PUC from Govindram Seksaria Science College, Belagavi. Later completed Mechanical engineering from Angadi Institute of Technology and Management in Belagavi.
During his free time, he noticed some small children using the playground and filling up their plastic water bottles from a potentially unsafe tap. Bearing witness to the scene, Niranjan reflected sadly on this reality and felt that all children should have clean water despite their income or area of residence. It was certainly not a surprise for the young leader to think of such social issues, given his involvement in the LEAD program at AITM College Belagavi. But it was this particular case that leads him to create something that would make a significant social impact for many people.
Water filtration became the main theme for Niranjan as he began to brainstorm ideas on providing a clean, low-cost source of water. Seeing as his research revealed the relatively high prices charged by competitors for filters, the future entrepreneur settled on creating a water filter that was both very affordable and portable for bottles. His first prototype used materials that were easily accessible around the house but after some assistance from LEAD, a second prototype was created that took Niranjan 4 painstaking months to perfect. The result was a small filter that could be fitted into any standard plastic bottle with an incredibly low cost of 20 rupees.
At that point, all the hard work put into the prototype paid off. Approval was given by the Food Divisional Officer stating that the filter could purify up to 100 liters of water. Furthermore, Niranjan turned to social entrepreneurship as a means of spreading his technology by agreeing to receive tier-ii incubation support in Belagavi by the Sandbox-IMER center. Sandbox Startups was instrumental to the founding of the NirNal enterprise, officially registered with the Ministry of Micro Small and Medium Enterprises in Belagavi. Furthermore, the incubation center gave him a platform to pursue his ideas for his product while gaining business knowledge about scalability and validity for the purposes of society. Complete with networking events, partnership opportunities, mentoring, and investor meetings, Sandbox Startups was an essential springboard to Niranjan’s growth as a social entrepreneur.
The social impact of his product has been significant. With the distribution of his product to various villages, schools, and even India’s military, it is evident that NirNal has been widely acclaimed for its ingenious and inexpensive technology. But on a personal level, Niranjan is happy with the fact that children could use his filter, knowing that they would always have a reliable source of water as they grow up. Niranjan’s initial wish to provide clean water to everyone has become more and more of a reality through the means of his portable water filter. This reality was made possible for thousands of people as 12,000 units of his filter have already been sold.
Indeed, it is exciting to see how NirNal will scale with its water filters. Niranjan himself has stated that he would like to improve the unit even further while maintaining a low price, all while maintaining his goal of providing clean water to all rural people. If he were to truly succeed in his endeavors, there would be much cause for celebration for this ingenious invention.
