1. Objective and Expected outcome
The aim of this course is to build appreciation for science, develop scientific temper and help the student understand where and how science is linked to daily life. Our goal is to engage the first year students in the University in a manner that builds on the student’s high school experiences rather than simply reiterating them with more technical details and provide more information to memorize. At the conclusion of this course student would have experienced how science has brought a change in our daily life, provides comfort, and helps assessing past, present and future scenario of energy requirements. The course would also help in analyzing and interpreting data, and impart problem-solving skills. Students should also be able to appreciate interdisciplinary connections between various fields and associate with emerging new directions of science. A common integrative foundation for all students will foster tomorrow’s citizens to engage scientific issues from multiple perspectives and make better-informed decisions of societal relevance.
Every Semester, teaching will be spread over 16 weeks including two weeks for review.
