Sustainable Energy by David Mackay -- An excellent data-driven analysis of energy usage now and in the future. A must read for anyone interested in our energy use and its impact on the environment. Very readable presentation.

Slow motion video of falling water drops

Taken with a Sony RX100M6 using High Frame Rate video mode. Shot at 1,000 fps and saved at 25 fps, ie 40x slower than real-time. The RX100M6 has a 20 MP EXMOR-RS sensor, the same type used in the high-end pro Sony A9 full-frame camera. Normal sensors have a grid of wires on top of the sensor for reading the data from the pixels. This reduces the light falling on the pixels by about 30%. Data is readout serially on the grid which limits the number of frames per second. The EXMOR-RS sensor has the read wires and circuitry stacked directly under the sensor, resulting in better low-light performance and very high speed parallel readout of the image.
Parmod Kumar, Assistant Professor in the School of Engineering, used OpenFOAM to simulate a drop falling through air on a liquid surface. The simulation is remarkably similar to the real-life video.

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/

Friday morning dawned crisp and clear, with the campus covered with 1-2 inches of snow. 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
