Description: Just a decade ago, new technologies like photonics, micro-electro-mechanical systems, mechatronics, nano-system engineering and optoelectronics bloomed to mark the beginning of prosperity in modern physics. Today, all these technologies have developed into major subjects of their own with countless implications in our day-to-day life. The impact of physics in engineering is so enormous that a new area of research is emerging each new day.
Physics deal with the complex interaction of matter, energy, space, time. Engineering physics applies the laws of physics in designing modern industrial devices. With branches of engineering physics expanding at a strikingly fast pace, the career choices for students are also growing.
This book gives students glimpse of fundamental theories behind the working of advanced devices and the advantage of physical constants in constructing new and improved materials.
Subjects in Physics like electricity, magnetism and materials science deal with the understanding of interactions of particles at atomic level. In visualizing such microscopic phenomena, a great deal of imagination and perception is required of students. Therefore, a book that limits itself to usual 2D outlines obstructs the power of imagination.
This is an illustrated book that comes with colorful images, enriched with gradation and transparent filling, to make great visual appeal to students. A smart lecturing coupled with inspiring presentation in this book is sure to offer a memorable, refreshing learning experience for students.
This book takes the advantage of a revolutionary technique (vectorized graphics) in bringing out all the drawings close to reality. Vector graphics incorporate edge detection, anti-aliasing, gradation and numerous other technical features to add clarity and precision to images. In essence, drawings reproduced in this book can be easily committed to long term memory of a visual learner.
