During this summer semester, I took part in the course

“

Introductory Nanoscience and

Nanotechnology

”

. In the four days, I truly believe I got a lot by the professor

s lectures. In the end, I

read the lecture

”

given by Richard P. Feynman in 1992. This

lecture was regarded as the beginning of nanoscience and nanotechnology. Now I will talk about

my options and views about this lecture and nanoscience and nanotechnology.

I have to admit that Mr. Feynman represented a totally way to observe the experimental physics.

There are lots of fields seems to be bottomless and in which one can go down and down.

Nanoscience and Nanotechnology is such an amazing field. Having grown rapidly during the last

two decades, and successfullysynthesized the achievements of physics, chemistry, life science

aswell as information and computational science and technology,nanoscience and nanotechnology

have emerged as interdisciplinaryfields of modern science and technology with various

prospectiveapplications towards environmental protection and the sustainabledevelopment of

industry, agriculture, public health etc. At thepresent time, there exist many textbooks, monographs

andencyclopedias on nanoscience and nanotechnology. They present to us, students the whole

process of development from the emergence ofnew scientific ideas to comprehensive studies of

concrete are useful for experienced scientists in nanoscience andnanotechnology as

well as related scientific disciplines.

This course,

“

Introductory Nanoscience and Nanotechnology

”

is extremely adaptive for us who are

preparing for learning material chemistry. The purpose of this course is twofold. In a pedagogical

manner. Theprofessor presents the basic physical and chemical concepts ofnanoscience and

nanotechnology. Students with a backgroundknowledge in general chemistry and semi classical

quantum physicscan easily understand these concepts. On the other hand, bycarefully studying

the content of this text course, readers can learnhow to derive a large number of formulae and

expressions whichthey will often use in their study as well as in their future researchwork. A

distinguishing feature of the course is the inclusion of a largenumber of thought problems at the

end of each chapter fordemonstrating how to calculate the numerical values of almost allphysical

quantities involved in the theoretical and experimentalstudies of all subjects of nanoscience and

nanotechnology. Theprofessor has successfully achieved both of the main aims of thecourse.

The courselasts for 4 days. This course is very useful not only for training beginners inresearch

and engineering in nanoscience and nanotechnology, butalso for attracting the interest of

specialists in other scientificdisciplines to the application of the achievements of this new emerging

multidisciplinary scientific field.

“But

I am not afraid to consider the final question as to whether, ultimately---in the great future---we

can arrange the atoms the way we want; the very

atoms

, all the way down!

friend of mine

(Albert R. Hibbs) suggests a very interesting possibility for relatively small machines. He says that,

although it is a very wild idea, it would be interesting in surgery if you could swallow the surgeon.

You put the mechanical surgeon inside the blood vessel and it goes into the heart and ``looks''
