In a new interview, <keyword id="10387" type="CITY" weightage="20" keywordseo="Microsoft">Microsoft</keyword> co-founder and richest man in the world <keyword id="45830" type="PERSON" weightage="20" keywordseo="Bill-Gates">Bill Gates</keyword> explained the potential for chat-bots in education. Gates lauded the potential for what he calls "dialogue richness," where a chat-bot can really hold a conversation with a student, essentially making it into a tutor that can walk them through even the toughest, most subjective topics. One of the Indian companies seems to have put this into use and that is <keyword id="187342" type="COMPANY" weightage="20" keywordseo="PagalGuy">PaGaLGuY</keyword>. <keyword id="3347386" type="UNKNOWN" weightage="20" keywordseo="Prepathon">Prepathon</keyword>, a test preparation app by PaGaLGuY, is the first bot in education and has taken early lead in the future-changing zone of BOTS. This bot gives progress report like a teacher, makes study plans like a tutor, provides revision practice like a coach and motivates like a mentor. Business Insider got chatting with the founder <keyword id="2608266" type="UNKNOWN" weightage="20" keywordseo="Allwin-Agnel">Allwin Agnel</keyword> to understand how this interesting thing works, and what are his future plans with Bots: 

	1. When did you first decide to have a bot? 

	- We first thought of bots last year when we saw the amount of repetitive work our coaches had to do. We felt we could automate the responses in order to reduce some of this work load. This included answering some very basic questions and also messaging the users asking them to study the topic of the day, to motivate them and so on.
 

	2. When was the first bot launched? 

	- The first bot was launched last year in the month of December - it was the "topic of the day" bot. The bot had to message users in every course the topic they had to complete for the day and if they didn't complete it - the bots would send reminders to the students.
 

	3. What are the other bots you have? A brief description of each…

	-We are planning to launch 4 more bots by the end of next month and will go on adding 1 new bot each subsequent month. 
	 
	We have launched 'Feedback' recently: Lets the user know about his/her performance on Prepathon, taking into account how much time they have spent answering questions, how many questions were answered correctly and the assessment of one’s performance w.r.t everyone else.

	We will launch 'Announcement': Makes sure one gets all important updates such as exam deadlines, new course material etc. from the course creators. Then would be 'Revision': Automatic provision of suggestions on the topics the user needs to revise. This is based on a spaced-repetition algorithm, to ensure that the candidate remembers the information which was studied previously. Then will come 'Motivation': For days when the user feels that his energy is not quite 100%; the motivation bot helps lift their spirits by offering easier goals, showing how their peers are doing on Prepathon, etc. 
	 
	Each of these bots will use varying degrees of machine learning and AI to keep getting better at what they do.
 

	4. So how have bots helped you in solving problem areas? 

	-The bots have significantly reduced the amount of time coaches have to spend on doing repetitive work. For example, our bots tell our coaches the no of people who haven't logged in within the last week and will suggest a single click message broadcast option to send out reminders to the said audience in order to coax them into getting back to their studies. This feature essentially acts as a force multiplier helping us allocate our resources more effectively. 
 

	5. How does he see technology evolving the e-learning space going forward?

	-Technologies like bots will dramatically alter the way people learn. 90% of a teacher's job is to motivate, to correct, to advice and help students study their material. Bots are extremely good at doing repetitive jobs and therefore can help manage students at scale, which is something traditional teachers cannot. 
 

	Beyond this, bots open up newer avenues - bots will allow students to personalize their own learning experience. Students will be able to select the bots they want active or deactivated on a course by course basis. This level of personalization can be achieved through bots. We are the very beginning stages of technology changing the way we learn and I fully expect bots to be leading the change.
 

	6. Plans for the future of PagalGuy and Prepathon?

	-PaGaLGuY is India's largest student community and we'll be entering newer verticals this year. With Prepathon we intend to add 30 new courses by the end of the year and have a set of 10 bots to cater to a wide range of student needs.
 

	He concluded by sharing some insights about the online education space - "The goal of technology should be able to make people do things faster, easier and better. While technology has made content accessible, it hasn't necessarily solved the problem of getting people to learn better online. The biggest challenge for the online education space is to use technology in a way that allows people to learn more faster, better and more efficiently than ever before."

India is recognized globally for its premier engineering institutes IITs and IIMs. Students from these colleges are behind some of the world's unicorns. They have a history of producing some wonderful innovations for a better world. From efficient electric cars, autos running on hydrogen to machines for the blind - the diverse innovations inside the campus labs are usually aimed at solving the real pain points of people and making their lives easier. Big or small, their ideas have contributed to our society for years. They are out to revolutionize the world and we are simply proud of their stellar innovations. Let's go over some of them:

An App which Facebook ended up buying 
 Abheek and Soham were inspired to create Tagtile by an incident in a restaurant in San Francisco. The <keyword id="137562" type="PERSON" weightage="20" keywordseo="IITians">IITians</keyword> heard the restaurant owner complain about the websites and apps offering deals. Thus, Tagtile was launched in March 2011 to satisfy the merchants as well as customers with exciting deals and offers. Tagtile won many acclaims and became one of the widely used apps. It also received an award in October 2011 for Best Startup in a competition among 100-odd start-ups in the Silicon Valley.Initially a partnership deal, ended with Facebook buying the year-old product. The deal brought along an offer for Abheek and Soham to join Facebook as product manager and engineer.

Hydrogen Autos with less noise and Pollution may take over Delhi roads 
	
	
	
	
	
	<div type="image" msid="51806957" hostid="261"></div>











 Professor LM Das of IIT-D conceived the idea of using compressed hydrogen as an automotive fuel with Delhi's air pollution in mind . In the early '80s, it was a bold initiative — an idea ahead of its time. Lay acquaintances thought he was talking about making a hydrogen bomb. Detractors in the scientific community dismissed his research as a freak project. But Das soldiered on alone over the next three decades as associates came and went. He says - Unlike petroleum-derived hydrocarbon fuels, pure hydrogen does not produce toxic carbon monoxide or the heat-trapping carbon dioxide on combustion. There are no oxides of sulphur, nor any particulates. Water vapour and oxides of nitrogen (NOx) are the only byproducts. Although NOx is a pollutant, Das claims their engine has been optimized to reduce its emission greatly.

Designed and developed in just 95 days by two IIT Bombay students - Anurag Meena and Satyendra Meena - is a revolutionary machine which accepts used cans or bottles, and dispenses 300 millilitres of clean (RO and UV treated) drinking water in exchange. It is currently on a pilot test run at the IIT-Bombay boys’ hostel. In the coming months, it will also be installed in several other places in Mumbai and Chandigarh.
