Outline of Science

to find out what can be
proved or not proved—and the knowledge thus acquired. The word "science"
comes from the Latin word "scientia" meaning knowledge. A practitioner of
science is called a "scientist". Modern science respects objective logical
reasoning, and follows a set of core procedures
or rules in order to
determine the nature and underlying natural laws of the universe and
everything in it. Some scientists do not know of the rules themselves, but
follow them through research policies. These procedures are known as the
are statements that describe or predict a range
of phenomena behave as they appear to in nature. The term "law" has
diverse usage in many cases: approximate, accurate, broad or narrow
theories, in all natural scientific disciplines (physics, chemistry,
biology, geology, astronomy etc.). Scientific laws summarize and explain a
large collection of facts determined by experiment, and are tested based
on their ability to predict the results of future experiments
. They are
developed either from facts or through mathematics
, and are strongly
supported by empirical evidence. It is generally understood that they
reflect causal relationships fundamental to reality, and are discovered
rather than invented.
is an interdisciplinary field about
scientific methods, processes and systems to extract knowledge or insights
from data in various forms, either structured or unstructured, similar to
Knowledge Discovery in Databases (KDD). Data science is a "concept to
unify statistics, data analysis and their related methods" in order to
"understand and analyze actual phenomena" with data. It employs techniques
and theories drawn from many fields within the broad areas of mathematics,
statistics, information science, and computer science, in particular from
the subdomains of machine learning,

based on empirical evidence. In natural
science, hypothesis must be verified scientifically to be regarded as
scientific theory. Validity, accuracy, and social mechanisms ensuring
quality control, such as peer review and repeatability of findings, are
amongst the criteria and methods used for this purpose. Natural science
can be broken into 2 main branches: life science, and physical science.

values such research more than other kinds. Empirical evidence (the record
of one's direct observations or experiences) can be
quantitatively or qualitatively. Through quantifying the evidence or
making sense of it in qualitative form, a researcher can answer empirical
questions, which should be clearly defined and answerable with the

and by the question being investigated. Many researchers combine
qualitative and quantitative forms of analysis to better answer

Exploratory research develops concepts more clearly, established
priorities, develops operational definitions and improve the final

design, data-collection method and selection of subjects. It should draw
definitive conclusions only with extreme caution. Given its fundamental
nature, exploratory research often concludes that a perceived problem does
not actually exist.

languages, folklore, and social structures.

a request for sponsorship of that research. Proposals are evaluated on the
cost and potential impact of the proposed research, and on the soundness
of the proposed plan for carrying it out. Research proposals generally
address several key points: What research question(s) will be addressed,
and how they will be addressed. What cost and time will be required for
the research. What prior research has been done on the topic. How the
results of the research will be evaluated. How the research will benefit

But the greatest power of science is that anyone
can be a contributor to this valuable knowledge resource, as millions
have done in our past.
And millions of people can
also benefit from this knowledge, whether they're living in the present or people who will be living in our
future. So all this accumulated knowledge becomes the building
blocks of new discoveries and new understandings. Not just progressing our advances
in technologies, but progressing our understanding of ourselves,
so we can be more aware
and make better
choices and make better decisions. Another benefit from science
is that, if and when things do change, we can use our knowledge
and tools to react accordingly instead of just suffering from
the changes in our world, or suffer from the changes in ourselves. So science is also part
early warning system, but only if it is used effectively and
something doesn't guarantee that
you will understand it, or learn from it, or benefit from it.
That is why knowledge is so extremely important, because
knowledge helps us understand our experiences a lot better.

something works does not mean that we actually know "why" it
works, or do we fully understand the dangers, because we don't know
everything. But we are learning a lot more now and we are
also learning faster now. And we are also communicating more and we're
communicating faster. But we're not efficient or effective
enough in order to benefit from our increased speed. So science
needs to solve this problem before we waste this momentum and
miss our chance in creating a better world for everyone.
Sometimes if you're moving too fast you may fly past important
information that you need in order to understand something. But luckily,
Science doesn't only speed up our ability to learn, science can
also be used to slow us down, so that we can see more details
and become more and more aware, so that we can make better choices and make better decisions.
just like every tool in our world, tools can be misused. So
science must explain the proper uses
and the proper
uses of our accumulated knowledge. Science must also explain the dangers of misusing our tools by creating a
that anyone can understand. Remember, science does not know
everything, but what science does know is extremely important,
and extremely valuable.

Scientists should stop trying to impress people with
knowledge, they should just give people the facts. One of the favorite
lines that scientists like to use is "You are made of the same elements as
. You are star dust". No, I'm much more
then just star dust. Just because I share many of the same genes as a
monkey, this does not make me a monkey. And just because my body is 90
percent microbes this does not make me a microbe. Scientist should tell
people more about the elements and the percentages, after that, then they
can share how wonderful it is to have
things in common

learning, not just impress people with wonder.
