The elucidation of the structure and stereochemistry of an acid named ‘C-11 Acid’ that played a crucial role in the determination of the molecular structure of abietic acid, which is a constituent of violinists’ ‘rosin’, led to a flowering of ideas of conformational analysis.
Ed Lorenz, rightfully acclaimed as the father of the ‘Butterfly Effect’, was an American mathematician and meteorologist whose early work on weather prediction convinced the world at large about the unpredictability of weather. His seminal work on a simplified model for convections in the atmosphere led to the modern theory of ‘Chaos’–the third revolutionary discovery of 20th century, the other two...
There is a way to describe a family of plane curves different from that using Cartesian or polar co-ordinates. This is a trigonometric equation involving two angles. In this article, we highlight the fact that trigonometric equations are convenient to describe certain one-parameter families of plane curves. In some cases, the trigonometric form makes it easier to characterize the family than if one...
The article gives a brief insight into the world of associations in the marine biome. Mutual co-habitation with plants and animals is witnessed among the lower as well as the higher groups of plants. In order for one to live, the other too has to survive. Hence, the dire need for conservation of India’s marine coastal biome is also highlighted here.
In this section of Resonance , we invite readers to pose questions likely to be raised in a classroom situation. We may suggest strategies for dealing with them, or invite responses, or both. “Classroom” is equally a forum for raising broader issues and sharing personal experiences and viewpoints on matters related to teaching and learning science.
Edward Lorenz discovered nonperiodic behavior in deterministic nonlinear systems and laid the foundation of chaos theory. He showed that chaos exhibits sensitive dependence on initial conditions implying that long-range weather prediction is difficult because of errors in the observations used as initial conditions. Lorenz described the intricate structure of chaotic attractors and quantified predictability...
Sun-Tsu wrote the treatise Sunzi Suanjiing around the 3rd century. The problem of finding an integer x which is simultaneously 2 modulo 3, 3 modulo 5 and 2 modulo 7 was considered. The smallest solution was found to be 23 and such a result is now called the Chinese Remainder Theorem (CRT). From early times–perhaps, from the 1st century itself–the CRT was employed in...
