BIOLOGY
Bios = Greek for:“life”
Logos = Greek for:“word”“rational account”“study of”“science of”
BIOLOGY
So, biology is ascience, the sciencethat studies life andliving things.
What is science?
Some Important Scientific Literature• Journals
Scientific American (all lay persons should subscribe to this)Skeptic (ditto for this)Nature (technical)Science (technical)
• Books What is This Thing Called Science, by Chalmers (McGraw-Hill)Scientific Method in Practice, by Gauch (Cambridge)Science: A History, by Gribbin (Penguin)Evolution: What the Fossils Say…, by Prothero (Columbia)
Science:the systematic attempt on the part of researchers to develop theories to explain the phenomena of our experience so as to classify, describe, organize, explain, explore, predict and, ultimately, control the phenomena.

phenomena of our experience…
Things that are publicly observable, 5 senses-able, testable, repeatedly, directly:
Things that are publicly observable, 5 senses-able, testable, repeatedly, indirectly:
molecules, cells, crystals, cats, dogs, ecosystem, solar system, Milky Way
gravity, electromagnetism, strong force, weak force, subatomic particles
Can you, I, anyone, and everyone experience it or sense it with one of the 5
senses directly or indirectly, repeatedly, by testing it in a controlled
environment?
Yes = scientificNo = non-scientific
5
NOT the 4 Ms:
M ind…in terms of “soul”M orality…right and wrongM eaning…purpose in lifeM agnificent Beings…god or gods
…these are outside the realm of the phenomena of our experience (OK to study and believe in, but not in science proper)
NOT these other Mseither:
M iracles…M artians… or other aliensM ind-control… like ESPM agic…
…these are outside the realm of the phenomena of our experience (OK to de-bunk, but not in science proper)
Intelligent Design:- The universe was createdby some superior intelligentmind (SSIM)- Life itself was created by SSIM- The highly complex things in the universe (e.g., eyes, flagellums, blood clotting) could not have evolved and had to be created by SSIM
Intelligent Design:- The universe was created by somesuperior intelligent mind (SSIM)- Life itself was created by SSIM- The highly complex things in the universe (e.g., eyes, flagellums, blood clotting) could not have evolved and had to be created by SSIM
Unfortunately for Intelligent Design:- Not part of the phenomena of our experience- Can’t be publicly observed, repeated, tested either directly or indirectly- There just is no science of Intelligent Design
False, too…
Some Literature on Intelligent Design• Science, Evolution, and Creationism, by the
National Academy of Sciences• Evolution vs. Creationism, by Scott (University
of California)• The Edge of Evolution: The Search for the
Limits of Darwinism, by Behe (InterVarsity) • Debating Design: From Darwin to DNA, edited
by Dembski & Ruse (Cambridge)
Intelligent Design:Does it belong in ascience classroom?Or, is it more appropriate for a religion or history class?How about… the study of souls? …what’s right and wrong?…the meaning of life?
Science:the systematic attempt on the part of researchers to develop theories to explain the phenomena of our experience so as to classify, describe, organize, explain, explore, predict and, ultimately, control the phenomena.
systematic attempt on the part of researchers…Scientific Method1 = ask relevant question2 = do background search3 = construct hypothesis4 = test hypothesis with experiment5 = analyze results of experiment
6a = if hypothesis is confirmed (true) = go to 76b = if hypothesis is not confirmed (false) or partially true
7 = report results8 = use results to construct more hypotheses
Science:the systematic attempt on the part of researchers to develop theories to explain the phenomena of our experience so as to classify, describe, organize, explain, explore, predict and, ultimately, control the phenomena.
to develop theories to explain…
Theory:- essentially a truth, body of facts- coherent system- confirmed hypotheses- laws (WHAT GOES UP… DOPPLER EFFECT…)
- deductions from these laws- overall… reliable predictions
to develop theories to explain…
Theory:- essentially a truth, body of facts- coherent system- confirmed hypotheses- laws (WHAT GOES UP… DOPPLER EFFECT…)
- deductions from these laws- overall… reliable predictions
E.g., Atomic, Big Bang, Evolution
And reliable predictions lead to:
- Developing better drugs to fight disease…- Developing early warning systems for tornadoes, floods, earthquakes…- Safer highways…- Spaceships and exploration…
and the list goes on and on…
Biology:the systematic attempt on the part of researchers to develop theories to explain the organic (living) phenomena of our experience so as to classify, describe, organize, explain, explore, predict and, ultimately, control the phenomena.

So… what is Life?- Replication…DNA, RNA- Encapsulation…cell wall, barrier- Self-Movement…growth, repair- Adaptation…homeostasis- Use of Energy in Multiple Ways- Hierarchically-Organized System

- is a single cell alive?
- the organelles that make up a cell? (Mitochondrion, Golgi Apparatus)
- a virus?
- a prion? (abnormal protein)
- the ecosystem itself?

Information Sciencescience associated with the collection,categorization, management, storage,processing, retrieval, and dissemination ofknowledge and information, often timesusing computational tools… think librarian,but a librarian with computational skills…
OVERALL GOAL:
KNOWLEDGE SHARING
What I Do:
BIOMEDICAL INFORMATICS More specifically, I help biomedical researchers:(A) classify their data and information in their labs(B) build links between and among all of their labs so that they can share the data and information with each other
classify, describe, organize…

with domain ontologies
with formal ontologies
Domain:
Area of study like biology, law, psychology, or any other science or discipline you would find at a university
Domain Ontology:
A classification kind of like:
Periodic Table of the ElementsKingdoms of Biology
in some domain (like biology, law, psychology, or any other science or discipline you would find at a university)
So, instead of using a STANDARD like the Periodic Table of Elements, people start classifying things their
own different ways…
this results in…
PROBLEM:DE-SILOING all of this
domain data and information so that it may
be queried effectively, shared, and
re-used(like Google-izing it)
Assists in making communication between and among domain ontologies possible by providing:
- Common language- Common formal framework for reasoning
So, just as ENGLISH is a common world language enabling different people to communicate in common…
So too, FORMAL ONTOLOGY is a common “language” enabling different domain ontologies to communicate in common…
Formal Ontology is like a “backbone” or “spine” making communication,
interoperability, and optimal dissemination of information possible between and among
domain ontologies.
