Lectures on Classical Differential Geometry: Secon&hellip by Dirk J. Struik

Got this book after reading the other reviews.
Forget this one if you think you will learn even a little of basic differential geometry from this book.
Throughout vector and matrices are uses on curves and surfaces straight away.
If you want to use it for self-study like I did then steer clear of this one.
May others are nicer - I ended up using the other book Elementary Differential Geometry(2nd ed ) by B.O'Neill.

4.0 out of 5 stars the mechanism thats locks one weight to the other looks a little flimssy, 9 Nov 2012
Just got these so will update on how long the mechanism lasts - the locking mechanism is a bit of plastic the comes out of near where the switch is and then goes into a groove into the other weights that's next to it.

It looks solid enough that it can carry the full set of weights on the dumbell. Only time will tell if this mechanism will last when used regularly.

Its very easy/quick to add/remove weight as all you do is put it on its base and flick the switch on top.
The bar you grip is proper metal and so has a solid feel. At the end of the bar is a screw that you use to lock the first dumbell to the bar. Then add on more in turn and the mechanism on top of each… Read more

I find this book very clear in its explanations . Takes you through calculus , vectors etc with plenty of examples.
Makes good use of diagrams which is where a lot of maths books fail - no idea why a lot of other books don't use more diagrams when most concepts can be put into geometric form for simple cases which makes it much easier to see whats going on rather then endless pages of equation and algebraic manipulations.
I use this book to understand the maths required for studying physics and so far its been clear.
