Book reading experience and the ultimate technology
The computer is just a feeble attempt of humankind to replicate the workings of a unique invention,
while science is an attempt to understand the craftsmanship of the greatest masterpiece – Nature.
As we all know, scientists can only replicate carbon-based life forms. They cannot literally make from
out of thin air any genetic material. They rely on raw materials from resources provided by nature. It
[5] is just like trying to simulate the functions of the human brain by inventing the computer. The brain
is the fastest and most powerful multimedia computer that exists in the present. It is organic, self
upgrading and has high articulation. The computer, on the other hand, cannot help itself without the
intervention of humans.
A computer hooked to the internet provides access to all the knowledge of humanity. However, there
[10] is a downside about this convenience. It deprives the human brain the necessary thinking skills and
training for data hunting and information processing. A student today only needs to access the internet
to do research homework. However, the learning experience is defeated since it is not the student who
researches the data needed for the school homework but the web browser. So where is the selective
learning process?
[15] If carrying books is so tiresome, mobile devices like smart phones will do the trick. All a student has to
do is search in a web browser for the Intext free eBook reader, for example, and then hit enter. While
there are lots of commercially available eBooks being offered out there, education must not be so
costly. That’s why there are millions of electronic books downloadable all over the world for free.
Reading books, either printed or the electronic version, provides the learner the essential mental
[20] training for data hunting, logical reasoning for information processing and the uncanny ability to
differentiate truth from lies, right from wrong, facts from fallacy, real from a hoax and the appropriate
from the inappropriate.
In the process of reading a book, a learner elevates the capacity of the human brain for stimulation of
the senses by indexing information for instant recall and further developing comprehension through
[25] mental processing of data.
Nature is the “Ultimate Technology” and the human brain is one of its most powerful inventions. We
are zillions of years more advanced as compared to our technology. However, digital media such as
e-texts can surely serve as invaluable and easy to access reading material. Thus, let’s take advantage of
this technology to the fullest by engaging in reading extensively in order to enhance our natural skills
and talents.

Além disso, as células-tronco podem ser programadas para desenvolver funções específicas, tendo em vista que ainda não possuem uma especialização.
Basicamente, as células-tronco podem se autorreplicar, ou seja, se duplicar, gerando outras células-tronco, ou ainda se transformar em outros tipos de células.
