11	Sat 22 Jan 2022	The Promise (and Perils) of Data Science	SCIS Foundation Day Lecture, University of Hyderabad. By video from IIT-M Research Park.	Data is everywhere. Almost every new product comes with sensors and an Internet connection. Data collected by these billions of sensors is continuously uploaded into ever growing cloud storage. Every facet of our lives, is being captured in this cloud of data. The promise of data science is that companies can use this data to give better service to their customers and to grow their business, governments can use the data for better, more transparent governance, ordinary people can benefit from better education, health, income, friendships and quality of life. The reality has been a mixed bag. While weather prediction is becoming more and more accurate, cloud bursts devastate mountain regions without warning. Facebook fosters global connections, helps us find long lost childhood friends, but it also fosters deadly hate groups. What is Data Science? How is it related to AI and ML? Why has it suddenly come to prominence? How can we reap the benefits of Data Science while avoiding its pitfalls? We will explore these questions during this seminar.
10	Thu 16 Dec 2021	BTech = Engineering? (pdf)	Orientation for 1st BTech students, IIIT-Una	Engineers have been serving society with products and infrastructure such as bridges, buildings, plows, caraiges, etc for 1,000s of years. BTech was started only in the last 200 years. What is engineering? How did engineers learn their skills without BTech? Is a BTech needed for engineering? These questions are addressed in this seminar.
9	Fri 21 May 2021	Photography: Get Rich or Get Famous? (pdf)	Lecture-demo arranged by the Photo & Movie Club, IIT Mandi.	Every photographer dreams of seeing his/her photos in NatGeo, of some wealthy collector buying a photo for millions. With the sophistication of digital camera technology, it seems that this dream is just around the corner. Alas, there are millions of other would-be greats pursuing the same dream, and only a handful of prizes awaiting. So, should we give up photography and take to a more sparsely populated, less competitive field such as growing prize bitter gourds? It is here that Wikimedia Commons comes to the rescue. Any photographer with a modicum of talent by putting in consistent effort, can earn fame, if not fortune, by contributing their best images to the Commons. In this lecture-demo, we will talk about Commons and walk through the process of submitting images. Most importantly, we will explain what is need to get your submissions noticed. We will give examples from the journeys of IIT Mandi Wikimedians who have started to make a name.

From Shingo La, the road descends to the Lungnak Valley. The Gonbo Rangjon mountain is an impressive rocky cone that rises precipitiously from the valley floor. We stopped for tea at a campsite near the base. The owner told us that with the road construction, trekkers have declined in number. The road runs along the right bank of the Kargiakh Chu river until the confluence with the Tsarap at Purne. En route, we stopped for a sandwich lunch opposite Testa, a left bank village. The views were spectacular with brilliant blue skies in the crisp, clear high-altitude valley. Here and there, road work raised some dust but it soon died down. After crossing the Purne bridge, the road enters a narrow gorge on the right bank of the Tsarap Lingti Chu. Nearing our destination, we were blocked for 2 1/2 hours due to blasting of the cliff to widen the road. We reached our destination, Hotel Rigyal in Padum at about 8 pm. After the pass for most of the way to Padum, the road is unpaved and under construction. In a few places, there is water flowing over the road. Contrary to popular advice, the road is motorable in a small vehicle with good ground clearance such as a Maruti Ignis or WagonR. A skillful driver is necessary. DSC_0187.jpg is by Pavin Samuel.

At an elevation of about 16,600' (5,050m), the pass separates Lahaul, Himachal from Zanskar, Ladakh. The nearby Shingo Ri peak about 20,000' (6,000m) dominates the pass on the east. Just below the pass on the Lahaul side is a small lake. This feeds the Jankar Sangpo stream, a left bank tributary of the Jankar Nala, which meets the Bhaga river at Darcha. The 40km road up to the pass is paved. Beyong the pass, the road is still under construction by the BRO. There is a light covering of snow at the pass even in summer. The Lahaul side gets more snow with lovely views of snow-capped ranges. The Zanskar side is drier and the mountain peaks are mostly bare rock above scree slopes. For more images see the Commons collection on the Shingo La pass.

The sky was intense blue with a few clouds, the bright sun was pleasantly warm. Before breakfast, I walked along the deserted NH3 through Gemur photographing some buildings in the village. After breakfast, Manas and I walked down to the jhulla to cross the Bhaga, assisted by a local farmer. We climbed up a scree slope to reach a small waterfall. The slope had seabuckthorn, wild roses and assorted small plants amidst rocks small and big. After enjoying the view and a snack, we walked down to the jhulla through fields of broccoli. In the afternoon, we climbed the path behing Gemoor Khar for about 700m to reach the Gemur Gompa (monastery). The original monastery was built centuries ago, but was destroyed in an avalanche. The current building was constructed in the 1970s. It seems deserted except for an old caretaker who was glad to show us around. The Gompa has several clay statues and assorted murals on the walls. There is a lovely view of the Bhaga and the Gephan mountain range on the opposite east bank. For more images on this area, see the Commons collections on the Gemur village and Monastery.

We drove through the Rohtang Tunnel and stopped at Tandi. Clear blue sky with scattered clouds, crisp cool air, hot in the sun. The Chandra and Bhaga Rivers meet here. After a cup of tea, we proceeded across the Bhaga over the Tandi Bridge and on past Keylong to reach Gemoor Khar, Gemur about 12 noon. In the afternoon, we drove to Darcha, crossing the new Barsi Bridge, and stopped the car just after Darcha on the narrow road to Yoche village. We walked along the road most of the way to Yoche. The hills were barren and dry due to autumn, with scattered small junipers and clumps of yellow birches varying the colours. The taxi picked us up near Yoche and drove us back to Gemoor Khar.

Took us 5h15m. We stayed at Paradise Holiday Resort, elev. 8,000', near the top of the village, a steep 10-min hike from the parking lot through the village. At night, the village is garishly lit by coloured lights in the multi-storey hotels, music blaring from some of them until 11 pm. Sat 13th: the sun touched the peaks opposite shortly after 7 am. Hiked 1,000' up a steep trail to Kutla, then across meadows and pine forests to Glacier Point. Scenic view of the stream and mountain, though the glacier has largely disappeared. Stopped for lunch in Kutla. Total 10 km, 6 hours. Sun 14th morning: checked out of the hotel, drove across Pulga Dam on the Parbati River near Barshaini. Steep climb to Kalga village, with good views of Barshaini and Tosh villages. Kalga is a spread out village on a plateau with houses and homestays interspersed in apple orchards. Crowds of trekkers starting on the Kheerganga trek up the Parbati river. Departed about 12:30 pm, stopped at Kasol for lunch, reached IIT at 5:45 pm.

We started walking just beyond the turnoff to Kandal Cross Shrine. It was a cool, overcast day. There is a Forest Department barrier that blocks cars and trucks, minimizing human presence. The road is lined with stands of young eucalyptus forests on either side. The spacing between trees is too small, resulting in few branches. Most of the old eucalyptus trees are dead, though many are still standing. Some have fallen, and the Forest Department keeps the road clear. The reservoir was a few feet below high water level. The water is a rich green, due perhaps to algae from the town sewage treatment plant in Kandal. We saw a few Indian spot-billed ducks, a couple of cormorants and a red-wattled lapwing. Plus a good number of house crows and a few songbirds Approximate route Distance: 5.5km, time: 3 hours

Drove beyond Sirudavoor village to stop opposite the SE edge of the lake at 7 am. Walked across a paddy field to the bund along the lake. Pleasant shaded path on the bund, with glimpses of paddy fields on the east and the lake on the west. Sounds of babblers and other song birds, but not many visible in the dense vegetation. Light mist over the lake, that soon burnt off with the rising sun. After walking for 1/2 km, we returned to the car and drove to the gate of Tuscani at the NW corner of the lake. Met Lakshmi V. shepherding a flock of young birders from IITM. As Tuscani was decorated for a wedding function, we walked along the road beside the lake. Saw a few kingfishers on the electric wires, and blue-tailed bee-eaters in the trees/bushes along the lake. A solitary egret and a few lapwings flew overhead. Migratory birds are perhaps already moving northwards?

Joined en route by Ambareen and Ram at Kelambakkam. Started walking at 7 am. A cool morning, partly overcast. Besides birds, the only life was young villagers speeding along the road on their 2-wheelers. After an hour of walking along the lake, we went into Tuscani resort and spent an hour there. It has a large area of paddy fields with a few plots yet to be developed. Many birds in the fields. Stopped at Sangeetha ECR for dosai and coffee on the way back. Quite popular on a Sunday morning, a result of the steady abatement of COVID. Pictures by TAG, except one picture of TAG by Ram.

Enakshi and friends joined from IIT Madras (about 1h10m drive for them). After driving around in circles for half an hour we found the lake. The sun was high in the sky and the air a bit hazy. We saw a collection of water birds. In anticipation of good birding, I had loaded my 200-500 mm lens, tripod and monopod in the car. At the lake, I found that I had forgotten the camera body to go with the lens! Being absent-minded is good for one's reputation as a professor, but not good for memorable bird images! :-) Enakski kindly loaned me her Nikon P600, a vintage long zoom compact camera that takes decent images. The locality is peaceful albeit without much shade from the sun. Besides birds, the only life was young villagers speeding along the road on their 2-wheelers. After an hour of birding, we enjoyed fresh coffee and Christmas cake in the shade of some trees before the drive home. Pictures by Enakski and TAG.

Started walking at 8,500', initially a steady climb through stately deodars. After 1 km, the forest gave way to the open meadow leading to Lake Prashar. After the recent rains, the grass was a lush green, with numerous small streams flowing down the hillside. As sunshine gave way to mist, we turned back and off the road in a narrow pass through to the Kullu side. Past a Gaddi herder's hut and came upon a serene albeit muddy pond. We sat and enjoyed the view with snacks and steaming coffee from a flask. Returned to the car after a hike of about 6 km in 2.5 hours. The drive back to Salgi took 1h15m.

A lovely setting. They have tent cabins with all the fittings and furniture of a high-end hotel room. The staff were very helpful, though the food was mediocre. An over-priced place in our experience. We went on a Gypsy safari in the Nagarhole Nat'l Park. Saw few animals and several birds. The boat safari on the Kabini Reservoir was more peaceful, though with fewer sightings compared to our trip in April when the water level was lower. The safaris are run by Jungle Lodges. Bison provides transport to and fro, but this adds 1/2 hour or more to the safari time. One evening, we went on a nature walk near the Bison Resort through some fields with several sightings of birds. The weather was monsoonish. No rain, but clouds in the blue skies. Lovely sunsets.

The group of monuments includes bas-reliefs and rathas (chariots) carved out of single granite boulders, cave temples and structural temples. Most of them date from the Pallava period (7th-8th centuries AD). It was a clear warm day with light overcast to moderate the heat. We started at 8:30 am at Krishna's Butterball. Then, we walked along the road to view the Descent of the Ganges, a relief carved in two huge granite blocks. Further down the road, are assorted cave temples and structural temples. Near the Lighthouse is an unfinished "practice panel" that may have been used for experimentation before the sculptors started on the main panels. We walked down the road to the Pancha (Five) Rathas, about 1.5 km from our starting point. The road was shaded, with touristy shops selling rock sculptures, handicrafts, etc. Many were closed, perhaps a result of the pandemic. Next to one of the rock sculptors was "Body Sculptors", a fitness studio! The area is kept clean and we saw one clean public toilet. The views of these five rathas, each carved from a single boulder, was partly obscured by a large group of school girls. On the way back, we stopped for cool drinks and took in some very modern street art painted on a wall beside the road. The Lighthouse was a visibly dominant structure, showing various faces as we walked around it. Returning to the main monument group, we climbed up to the Iswara or Olakkanesvara temple built on a hillock. It affords good views of the Lighthouse and the surrounding countryside. Then we walked past several temples, including the incomplete Royagopuram possibly dating from Vijayanagara period (1336–1646 AD). The walk ended back at Krishna's Butterball at 11 am. The image of the photographer shooting the lighthouse was taken by Danica. Hires versions of most of the images, suitable for printing, can be downloaded from Wikimedia Commons.

When I last visited the Mount in the 1990s there was a quaint old chapel built in the 1500s. Now, it has been renovated into a vast modern shrine. The only vestiges of the old that I found was a gravestone of Anna Jacobyan dated 1764 in the floor at the entrance to the church. Planes were landing from the NE, so we had good views of the planes almost level with the Mount on one side, and the planes touching down on runway 07/25 on the other side.

We went up to a big flat rock called Micro View Point. With scattered high clouds, the sun was hot and the strong winds dehydrating. In the afternoon, I conducted an exercise in product design for 10 faculty who will be leading the LEAP course for 2nd BTech students starting in May. The faculty enthusiastically worked in cross-Department teams. Each team selected a problem from their daily life, brainstormed on possible solutions and worked out details of one of their designs.

This is on a range to the NE of the Idukki Reservoir, about 1,000-1,500' above. The Mount is an ecotourism park, Kalvari Mount, maintained by the Govt. It has the Stations of the Cross along the path and a large cross at the summit. Guided by K.S. Sunil of the CSE Department, we spent a couple of hours walking up to the top of the Mount. The views of the reservoir and the grassy mountains beyond to the south and west reminded one of the Nilgiris and Scotland. To the east we had vistas of the foothills and the Western Ghats, reminiscent of the views of the Shivaliks near Kamand. After descending, we had a home-cooked breakfast thoughtfully provided by Reena. On the way back to Idukki, we stopped to view the rear of the Idukki Dam. Without any spillways, it is an unbroken double arch of white concrete. The spillways are in the nearby Cheruthony Dam. In the afternoon, I conducted an exercise in reverse engineering for 10 faculty who will be leading the LEAP course for 2nd BTech students starting in May. The faculty were quite enthusiastic to reverse engineering assorted common products. PC: R16_05639.jpg -- P.T. Gonsalves

We set out on the gypsy safaris about 3 pm and returned 3-4 hours later. Good sightings of many animals and a few birds. The scenery was monotonous, mostly teak forests, some variation when we approached the shore of the Kabini Reservoir. The ride is rather bumpy.

Down to the jhulla across the Bhaga, about 08:45 am. On the left bank we climbed over rock piles and thorny shrubs to an open grassy slope on the left bank of a stream up to a waterfall. Had snack and enjoyed the view before returning. Reached about 12:45 pm. The area is much drier with browns, yellows and splashes of red and purple compared to the earlier visit in July 2016. Seabuckthorn has dry leaves and copious yellow/orange berries that have a sharp astringent taste. Wild roses with bright red rose hips (fruit). Aromatic sage plentiful, brown grass and stunted juniper on the slopes. Flushed about 10 snow partridges in the rocky slopes opposite Gemur. In the afternoon, at 3 pm we drove to New-Darcha. Walked along the spur road up a river about 5 km to the last village Yoche. Vast scree slopes from the road to about 1,000-2,000'. Peaks about 4,000' above us with small ice-fields. At the end of the valley is the snow-capped M10, 5,840m (19,160'). Extensive cultivation on the riverbed. Potatoes being loaded into lorries. Bright yellow paper birch or aspen (?) on the slope provide relief from the dark, stark rocks and green junipers. Met two oxen, two cars and the Keylong-Yoche bus. The peaks around Gemur and Darcha are mostly barren except for a few icefields near the summits and some small glaciers. Above the valley floor at 10,500', there are stunted junipers and a few birch/aspens up to 12,00'. The 5,700m (18,700') peak south of Gemur towards Sissu has a large cover of ice and snow that catches the sun's rays about 6:30-7:30 am.

The broad new 2-lane road is a far cry from the narrow single lane road that we took 4 years ago. The road climbed steadily from a barren valley with ranges towering to 16,000'-20,000' on either side, scree slopes of 1,000' and only a few beds of plants, dark red with approaching winter. After the helipad at Zanskar Sumdo (11 km from Darcha), the road turned into rubble and dust. The going was slow with crews at work. By about noon we had reached 14,000 near Ramjak, 9 km from Sumdo and still 10 km short of the Shinku La. We stopped in a level area and walked down to the river. Walked upstream with views of the rounded snow-capped Shinku Ri peak, looks like Mt. Kailash. A stark contrast to the rugged mountain slopes. There was ice in shallow pools in the Jankar Nala. Returned with several halts en route to enjoy the rugged scenery. Stopped at Paldun Lamo where the river flows through the narrow cleft in the road about 100' deep and 40-50' wide. A Buddhist shrine has been developed. Reached Gemoor Khar about 03:30 pm for a late lunch. In the evening, we tried to cross the Bhaga at the Gemur campsite. A farmer was working in the fields opposite and had tied the jhulla on the far bank. Loath to disturb him, we drove to Jispa and walked upstream along the river for 2 kms. A mix of cratered walls, camp sites, seabuckthorn, potato fields and the sandy river bed. Near Jispa, the river bed broadens and the river becomes braided. Returned to Jispa on the road. From Thenu to Gemur to Jispa, the left bank of the Bhaga varies up to 200-300m wide, good for walking, mostly rocky scrub with a few fields. In one place between Gemur and Jispa and near Jispa, the scree comes down to the river. Perilous paths are visible. Except for Thenu which is on the left bank, all other habitation is on the right bank.

We crossed the Gemur jhulla at 9 am and led by Manager Rajkumar, we headed downstream toward a glacier at the top of the steep side valley about 1.5 km west of Gemur. Without a path, we traversed scree slopes of varying gradients. Some sections had 10-15’ junipers, others had grass, in places there was no vegetation only treacherous sharp broken stones. Climbing slowly upwards, we reached about 300' above the river with a view of the glacier at 11:30 am. Rajkumar returned to Gemoor Khar. I stayed at the “base camp” taking photographs. Sree, Shyamlal and Jhaa headed towards the glacier. In an hour they progressed about 300'. Jhaa stopped at one big boulder, Sree and Shyamlal went to a bigger boulder ~50-100' higher. We returned to Gemur by a path lower down along the river, for another 3:30 pm lunch. In the evening, we drove to Khangsar about 1,000’ above Gemur. En route, we stopped to look down on picturesque Thenu village on the left bank of the Bhaga. Comparing it with pictures from July 2016, it was lush green then and dry brown after potato harvest now. A detailed comparison of the buildings indicated no new construction in 4.5 years, not even addition of a floor or rooms to an existing house. Perhaps due to a stable population and being off the tourist route. The Khangsar monastery was closed. We walked down the dirt road to Gemur Ghompa (monastery). Good views of the Bhaga upstream to Darcha. The setting sun threw the mountains beyond Darcha into warm relief. At the Ghompa, the caretaker opened it for us and gave us a tour of the whole building. It was getting dark as we returned to Gemoor Khar. To avoid the cemented path to Gemur, we clambered down a steep path above and on the far side of Gemoor Khar, by the light of one cellphone for 3 of us. Not recommended, though we made it back without any mishaps!

Light traffic to Sissu. Golden aspens or birch lining the road at Sissu. Drove up to Ghepan Monastery above Sissu. It was under renovation so we could not visit. Continued on past the Rohtang Tunnel to Koksar and up to Rohtang Pass. With light traffic, we reached about noon. Very few tourist vehicles at the Pass. We spent an hour walking across from Lahaul side to Beas Kund on the Kullu side. Stopped at Marhi for a late lunch. In Manali, we stocked up on exotic provisions at the Mall, and enjoyed coffee and fresh “German” cakes at Amigos Bakery. The drive back to Salgi was uneventful, with a stop to pick up fresh fruit outside Kullu. Reached home at 7:45 pm.

About 2h50m owing to road work. Stayed in the PWD Resthouse. Walked up the Uhl for 2 km before it got dark. On Saturday morning, we drove up the Uhl to Baragram. Walked 2-3 km almost to the end of the road. Returned for a late lunch of veg momos (mostly cabbage) and grilled trout. In the evening, Rik, Subrata and Rishu arrived. We walked along the Lamba Dug. On Sunday morning, we again drove up the Uhl part way. Walked up the road with an excursion along a side stream. After lunch, drove back home, stopping near Dyna Park to enjoy the sunset.

Enjoyed walks in the orchard and the mountains behind it. Drove to Manali Mall Road and Solang Valley. Drive from Salgi to Manali took 2h50m. On the return, we drove along the left bank road up to Kullu. Mostly a good 2-lane road, potholes here and there. Reached Bajaura in 2 hours. Due to a landslide near Aut, there was heavy traffic on the Kandi road, and the drive from Bajaura to Salgi took 3.5 hours.

On June 10th, as the flowers matured and the seeds ripened, a male plum-headed parakeet enjoyed breakfast of dozens of sunflower seeds. In about 10 minutes, he denuded one of the mature flowers. Then, he flew up into a nearby tree, and told his female friend about it. She spent a couple of minutes before leaving. Other insects also enjoyed the flowers, without damaging them.

Stayed in the PWD Resthouse with a good view of the river and the distant Dhauladhars. Spent the evening on a large mud flat beside the reservoir. Large numbers of bar-headed geese, many waders and water birds, a few songbirds and raptors. On Sun 26th, after an early morning walk through the town, we drove to the nearby Masroor Rock Temple, carved out of solid sandstone. Reminiscent of the rock-cut temples at Mahabalipuram south of Chennai. Dating from 8th century AD. Partly in ruins due to the Kangra earthquake.

In the mountains of the Nilgiris, clad in grass, eucalyptus, cypress and wattle, I imagined vivid mental pictures of the foothills of the Himalayas in which Corbett lived. In early December, I visited the Jim Corbett National Park to see Corbett country in person. The trip was very graciously arranged by Deepti (my MS student from IIT Madras) and Mayank and their delightful daughters, Meera and Vrinda. On the first evening, we spotted 6 tigers at close quarters, and one more on the next day. Other animals included elephants, cheetal, barking deer, sambhar, monkeys and wild boar. Birds were aplenty along the Ramganga River – eagles, a lammergeier, herons, storks, egrets, kingfishers, redstarts, barbets, bulbuls, etc. We spent many hours sitting peacefully in the grasslands or in the sal forest, soaking in the sounds of the birds, the wind sighing through the sal trees, alarm calls of monkeys and deer, and the occasional growl of a tiger and trumpeting of an elephant. Our guide/driver Imran was very knowledgeable and adept at spotting animals and birds. Most pics by T.A. Gonsalves, a few (C) pics by Kartiki Gonsalves http://www.kartikigonsalves.com/

By noon most of the snow on campus had melted, though the snow on north facing mountain slopes lasted for 2-3 days. The last time it snowed on campus was in December 2014 (the snow did not persist). The last time the campus was covered with snow is said to be in 1992. Pics by TAG, Neha Sharma and Merlin Sundar
