I need a good book on tensors, so that I can understand and get good hold of the topic. Can anyone recommend me a good book, like one used in undergraduate level?

Then try J.L. Synge, A. Schild, Tensor Calculus.Wrichik Basu said:Physics.

It's published by Dover, so it's probably cheap.
Alternatively, if you need it for general relativity, any textbook on GR has a chapter or two on tensors.

It depends on the perspective. The differential-geometry aspect of tensors is indeed essential in general relativity, but perhaps not so much in theory of elasticity. In the latter case, the algebraic aspect of tensors is perhaps sufficient.zwierz said:Tensor is an object of differential geometry.

atyy said:You can find lots of good basic material by googling "linear algebra multilinear tensor"
To go from tensor algebra to tensor differential geomtry, you can try Spivak's Calculus on Manifolds and Reyer Sjamaar's Manifolds and Differential Forms lecture notes http://www.math.cornell.edu/~sjamaar/manifolds/.
Two books I really like are Crampin and Pirani's Applicable Differential Geometry and Fecko's Differential Geometry and Lie Groups for Physicists. They give the translation between the mathematical notation using differential geometric objects and physicist's index gymnastics.

Hm, the notation in Chpt. 6 where he finally introduces tensor components (not as claimed tensors, but that's a common practice among physicists), is dangerous at best. One should really be very careful in not only make a thorough distinction in the vertical position of indices (indicating whether one has co- or contravariant components of tensors) but also the horizontal position. Otherwise it can come to ambiguities leading to great confusion. Also the prime indicating the other basis to which the components refer should be on the symbol, not at the indices. So Eq. (6.1) should in fact readsmodak said:

With this little more effort in notational clarity, which is a bit cumbersome (particularly with a bad handwriting like mine ;-)), pays off by being much more safe against confusing oneself in calculations with many indices.

Tensors are mathematical objects that describe the relationships between different physical quantities. They are important because they allow us to represent and manipulate complex physical phenomena, such as fluid flow, elasticity, and electromagnetism, in a concise and elegant way.
To understand tensors, a solid foundation in linear algebra, multivariable calculus, and differential equations is necessary. Some familiarity with vector and matrix operations is also helpful.
Some popular books on tensors for undergraduates include "Introduction to Tensor Analysis and the Calculus of Moving Surfaces" by Pavel Grinfeld, "Tensor Calculus for Physics: A Concise Guide" by Dwight E. Neuenschwander, and "A Student's Guide to Vectors and Tensors" by Daniel Fleisch.
Yes, there are many online resources available for learning about tensors, including video lectures, interactive tutorials, and online textbooks. Some popular websites for learning about tensors include Khan Academy, MIT OpenCourseWare, and MathWorld.
Tensors have a wide range of applications in physics, engineering, and computer science. They are used to model and analyze systems in mechanics, electromagnetism, quantum mechanics, and general relativity, among others. Tensors are also used in machine learning and data analysis for tasks such as image and signal processing, natural language processing, and recommendation systems.
