### Ambigram Poettery

I call it poettery, because it is the product of my pottering around the poetry format. Really, its not poetry in the sense of the word-- can't really say I don't really understand the sense of the word.

Ambigrams, though, are something that are really interesting, and people interested in math are likely to like them.

You can read Punya's flattered introduction to ambi-poettary here.

Logical

If o looks like a,

Then a looks like o,

and conversely.

Look at the mirror g

and tell me,

what can you see?

Through the looking glass

they say,

beyond what is

logical,

you can find

the meaning of life --

the universe, everything:

The number 42.

A-life (artificial life, spiral)

Originally uploaded by punyamishra

A Life

Changing a little

at a time.

A slightly different

point of view,

another shift

in perspective.

A Life,

you would think,

spirals endlessly.

Its an illusion:

Its finite,

like everything else.

is just a Pun.

You'll never know,

A good pun, ya?

A Life.

What a life!

It gets further

and further

from itself.

And smaller

forever.

And dissolves into

nothingness.

Turn it around

What A Life.

From A to E,

not worth living.

### Get Smart! Maths Concepts

The book Get Smart! Maths Concepts has been released by Penguin Books, India.

The book is a survey of middle school math, and covers concepts that I feel will be useful for all students to know. It may even give a quick review of things you need to know in pre-algebra and algebra, before you encounter them again in a calculus class. The emphasis is on thinking mathematically, rather than just learning the procedures to solve problems.

You can buy the book from flipkart.

### Book Released

http://www.penguinbooksindia.com/Bookdetail.aspx?bookId=7609

This blog is to answer questions if any from readers, post errata, and discuss solutions of the problems in the Do and Discuss section of the book.

### Acknowledgements

*From the book Get Smart! Maths Concepts, Puffin Books, India, 2008.*

I acknowledge the debt I owe to Professor Richard Askey of the University of Wisconsin. Most of the topics of this book are included in a beautiful handout made by Professor Askey. The handout outlines the essential aspects of algebra and geometry that students should know before they learn the Calculus.

I would also like to thank Vatsala Kaul, Penguin’s Editor for this book. Vatsala conceptualised this book creatively, and has clarified the exposition throughout this book. Further, I thank Shubhank Bhadauria and Tarun Sachdeva for creating the graphics in this book.

I thank the following people who are an integral part of my life, and who have encouraged me in one way or the other during the writing of this book: My school friends—Hartosh Singh Bal, Punya Mishra, Poonam Madan, Gaurav Suri, and Vikram Jamalabad. My colleagues— Jagdish Prakash, Shantanu Prakash, Abhinav Dhar, Sangeeta Gulati, and Meena Raju. And my family—Hem Bhatnagar, S. S. Bhatnagar, Saurabh Kumar, Amit Bhatnagar, Jayshree Bhalerao, and Priti Kumar.

Last but not the least, I wish to thank my daughter Tejasi. It is because of Tejasi and her friends that I rediscovered the joy of doing mathematics at the primary and middle school level.
