Biologically

Biology is a natural science that is concerned with the study of life, its various forms and its function, how these organisms interact with each other and with the surrounding environment. The word biology in Greek is made up of two words: bio (βίος) meaning life. And loggia (-λογία) means science or study. Biology: the similarity of vegetation and animal cover on the edges of the African and American states, and the existence of the same fossil.

Branches of biology
Biology is an ancient science thousands of years old and modern biology began in the nineteenth century. This science has multiple branches. Among them are:

Anatomy
Botany
Biochemia
Biogeography
Biofisia
Cytology or cell science
Ecology or environmental science

نبذه عن الكتاب:

The book is laid out this way. Chapter 1 covers some basic facts from
harmonic analysis. Most of the material there will be review for many people,
but we have tried to present it so as not to intimidate the non-experts. Chapter
2 introduces the one-dimensional dyadic square function and proves some of its
properties; it also introduces a few more techniques from harmonic analysis. In
chapter 3 we prove the exponential-square estimates mentioned above (in one
dimension only). These lead to an in-depth look at weighted norm inequalities.
In chapter 4 we extend the results of the preceding chapters to d dimensions
and to continuous analogues of the dyadic square function.
Chapters 5, 6, and 7 are devoted to the Calder´on reproducing formula.
The Calder´on formula provides a canonical way of expressing “arbitrary”
functions as linear sums of special, smooth, compactly supported functions.
It is the foundation of wavelet theory. Aside from some casual remarks1, we
don’t talk about wavelets. The expert will see the close connections between
wavelets and the material in chapters 5–7. The non-expert doesn’t have to
worry about them to understand the material; but, should he ever encounter
wavelets, a good grasp of the Calder´on formula will come in very handy. We
have devoted three chapters to it because we believe the reader will gain more
by seeing essentially the same problem (the convergence of the Calder´on integral formula) treated in increasing levels of generality, than in having one
big portmanteau theorem dumped onto his lap. The portmanteau theorem
(Theorem 7.1) does come; but we trust that, when it does, the reader is more
than able to bear its weight.
