The Way the World Works | Scientific Knowledge 4 of 9jkninstitute
Philosophy of science is a branch of philosophy concerned with the foundations, methods, and implications of science. The central questions concern what counts as science, the reliability of scientific theories, and the purpose of science.
An understanding of how science operates, if it possesses any real credibility and authority in its propositions.
Topics discussed:-
Laws of nature
Explanation
Theories
Possibility
The problem of induction
Science is knowledge through observation and experimentation. It is facts of principles gained by systematic study. In order to participate in doing science, we must adhere to a "philosophy of science:" There is order to the universe, humans are able to comprehend this order, and scientists should be able to repeat experiments. There are two major kinds of science - empirical science and forensic science. However, science can't answer a lot of questions, and scientists often make mistakes.

Hybrid RAID arrays of Solid State Drive (SSD) and Hard Disk Drive (HDD) offer tremendous performance gains over standard HDD RAID arrays by performing read operations from the faster SSD and write operations on both the SSD and HDD. The result is a higher number of read operations per second with no degradation of write I/O performance, and complete transparency to the operating system and all running applications.
Assignment 1BackgroundWhen you look around at the world, you .docxsherni1
Assignment 1:
Background
When you look around at the world, you can see many examples that demonstrate how an object's or a system's structure relates to its function. The structure of a highway system, for example, can affect traffic flow. You can, no doubt, think of many other examples.
In this Discussion Board assignment, you will look at the structure of the most basic unit of life, the living cell. You will also investigate how the structures of cells are directly related to the functions that are important to life.
Part 1
Your text describes the difference between the organelles in a eukaryotic cell and the more simple structure of a prokaryotic cell as an analogy between the chief executive officer's (CEO's) corner office and a cubicle. Organelles are like appliances or pieces of furniture that perform specific functions. Choose 1 organelle, and use an analogy to explain its function. For example, explain how a chloroplast is like a solar panel, or how a mitochondrion is like a furnace. Try to think of original analogies for other organelles or cell structures such as golgi, lysosome, cell wall, cell membrane, endoplasmic reticulum, ribosomes, nucleus, and so on. Include how your analogy may be less than perfect. Compare your analogy with those of your classmates’.
Part 2
You will read that only plants, algae, and some bacteria are photosynthetic. There is an exception to this, though. One species of sea slug has found a way to steal chloroplasts, store them in cells lining its digestive tract, and live on the sugar that is produced (Milius, 2010). What benefit would there be for animal cells (including those of humans) to make their own food? Could cell, tissue, or genetic engineering allow humans to use chloroplasts this way? Describe 1 or 2 factors that would need to be considered for chloroplasts to function in an animal or a human.
Reference
Milius, S. (2010). Green sea slug is part animal, part plant. Retrieved from http://www.wired.com/wiredscience/2010/01/green-sea-slug/
Assignment 2:
Scientific inquiry in biology starts by observing the living species around you. What separates science from the other methods of seeking truth is that it is testable (e.g., one can devise experiments to test the validity of an idea); it is falsifiable (e.g., an experiment can reveal if an idea is false); and it involves natural causality (e.g., the method involves and depends upon the natural laws of the universe which cause things to happen in a predictable and repeatable manner).
Observation: Scientific inquiry begins when something interesting gets your attention.
Question: Following an observation, a question arises in your mind. It may be something like "I wonder what?" or, "I wonder how? or, "I wonder why?"
Assignment Details
In this assignment, you will take a look at the scientific method. You will design a (fictional) scientific study to answer a specific question based upon an observation.
First, choose 1 of the following observations ...

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

The Art of the Pitch: WordPress Relationships and Sales
Nature of science and evolution
1.
2. Warm up
Classroom clean up. Your tasks are written on your
tables.
Create a Venn Diagram on your own sheet of
scratch paper. Compare and contrast similarities
between mitosis and meiosis. Use your notes to help
you.
FYI: I‟m still getting my voice back.
3. Nature of Science
We will now start our section on evolution. Before we
do, we need to understand how science works (nature
of science).
What would your definition of science be. Think about it
for a minute and then share with your neighbor. Be
ready to share out with the class.
Hopefully by the end we will talk about all of your
definitions.
5. Nature of Science
Science can only answer questions that address
natural phenomena (things we can see and
measure) not questions that are
subjective, political, religious, ethical etc.
Science is evidence based: uses standards of
evidence and logical ways to answer questions, all
of which are based on observations, tests, or other
types of data (CAN use the scientific method but not
always!)
6. Nature of Science
Testable and Falsifiable: Can be tested over and over
again and can be proven false by evidence
Consistent: A scientific explanation must fit all of the
observable facts or it is proved to be untrue.
Practical: The scientific explanation has work in the real
world outside of the lab setting.
7. Nature of Science
Making Explanations: must show a pattern of cause
and effect based on observable evidence
Reviewed by Peers: must be open to criticism by
other people. Usually other scientists
Self-correcting: Statements are made with caution
and scientists always note possible sources of error
and degrees of error
8. Nature of Science
Limitations of Science
Science is not absolute truth: scientific statements are
best approximations based on available evidence
Note!: This doesn‟t mean it‟s not reliable. Take
gravity for example.
Science is not Democratic: you cannot vote on science.
Science policy and laws may be voted on but science is
based only on evidence.
9. Nature of Science
Limitations of Science:
Confirmation Bias: bad science starts with a belief and
then looks for evidence to confirm that belief. Science
should start with facts and the beliefs follow after.
10. Nature of Science
A video: A video of a physics teacher explaining the
nature of science. He will probably make more sense
than all these notes….
Terms used to Describe Nature of Science
Fact: an observation that has been repeatedly
confirmed and for all practical purposes assumed to
be true. (Ex: Right now we can see the sun If we
walk outside)
11. Do you feel like your perception
of science is changing? How so?
12. Nature of Science
Terms used to Describe Nature of Science
Hypothesis: a temporary statement about the natural world that
can be tested. Used to build more complex inferences and
explanations
Law: A descriptive generalization about how the natural world
behaves (Ex: objects tend to fall towards the center of the
earth.)
Theory: A well-substantiated (well-tested) explanation of the
natural world and can incorporate facts, laws, inferences and
tested hypotheses.
13. Nature of Science
3 Things Scientists DO
Acknowledge and estimate possible errors
Identify their own assumptions
Publicize work and ask for criticisms
14. Nature of Science
It sometimes can be difficult determining what is a
scientific claim and what is not. Let‟s have a little
practice by taking this survey.
15. Nature of Science
The Nature of Science – You can’t handle the truth!
Directions: Work in groups of 2-3 Go to the class
website (hthbio2012.weebly.com) Under Assignments is
a Nature of Science Assignment Page. Pick 5 of the sites
and determine whether the sites are stating true facts or
not. Find at least one site that is stating true data. After
you determine whether the sites are true or not support
your statement with 3 different reasons. List 1 to 2
reasons why this site can be deceptive or make a reader
uncertain if the content in the website is true or not.
16. Discussion Rules
As we get into evolution, we might be getting into some sensitive
subjects. In order to maintain a safe class environment, we will all abide
by the following rules:
Listen and give your full attention to the person who is speaking
Only one person speaks at a time
Raise your hand to be recognized if you want to say something
When you disagree with someone, make sure that you make a
difference between criticizing someone‟s ideas and the person
themselves
Be respectful of everyone in the classroom
Encourage everyone to participate
Any other rules we decide at agree on
18. Nature of Science
“Everything you‟ve learned in school as „obvious‟ becomes
less and less obvious as you begin to study the universe. For
example, there are no solids in the universe. There‟s not
even a suggestion of a solid. There are no absolute
continuums. There are no surfaces. There are no straight
lines”
- R. Buckminster Fuller (1895-1983)
“The truth can sometimes be deceptive.”
- - Galileo
19. Warm Up
Finish the Nature of Science website activity.
When you are done, browse through the other website
you haven‟t visited yet. We will also go over those
websites later.
Honors: Take out SAT Book Page 224-245/Video Notes
21. Natural Selection
Natural Selection is theory that explains how
evolution works. Rather than take notes on natural
selection, we are going to do an activity and you will
try to come up with a theory for natural selection.
Take out Your Lab Notebooks
Title: Modeling Natural Selection
Purpose: To model and define how natural selection
works
22. Natural Selection
Popcorn Reading: As a field scientist…
Procedure: Popcorn Reading
- Cut and Paste the front page into Lab Notebook as
the procedure.
- Practice using your feeding apparatus. Create a
section called pre-lab questions and answer the
questions on page 2 of your modeling natural
selection handout in your lab notebook.
23. Warm-UP
Clear the tables of everything except a writing
utensil and your lab notebook or data sheet.
Practice using your feeding apparatus. Answer the
questions on page 2 of your modeling natural
selection handout in your lab notebook.
24. Results
Create a graph of your data that best shows which type
of pretendie was best suited for the environment over
time.
26. Warm Up
Take out your annotations and PD
Discuss the evolution reading packet and take the
evolution survey. Use the survey as points of
discussion. Be ready to share out.
Turn in the list of things you did for engineering in the
inbox
27. Back to Natural Selection
Create a Graph in your lab notebook that shows how
the number of different pretendies changed over time.
Then answer the post lab questions. Be ready to
discuss answers.
28. Natural Selection Notes
Take out a sheet of paper.
Natural Selection: The gradual process where biological traits become more or
less common.
Facts:
1. Overproduction and competition: the population of species has to produce
lots of offspring. Offspring compete with each other for food
1. Fitness: How many babies you can have that can have babies
2. Individual Variation: Individuals in a population vary (Ex: People look
different)
29. Warm-Up
How would you define fitness? In other words, when
you think of someone who is fit, what comes to mind?
Any questions about evolution?
If evolution is about survival of the fittest, do you think
there can ever really be true altruism?
30. Natural Selection Notes
Species organisms that have similar physical
features (traits), DNA, and can reproduce to make a
fertile offspring.
Mules and Ligers are not a species. Why?
31. Natural Selection Notes
Population a group of the same species living in the
same location at the same time
32. Natural Selection Notes
Fitness the ability of an organism to produce
offspring that survive and can reproduce
33. What is Evolution
Evolution is a change in population overtime and a
change in gene pool in a population over
generations
Gene pool: all the genes/DNA in the population
34. Natural Selection Notes
Darwin made two points in the Origin of Species
1 found evidence that new species had evolved from
ancestral populations
2 Natural Selection – explains how evolution works
35. Natural Selection Notes
Darwin‟s Theory of Natural Selection
1 Overproduction: organisms produce more offspring
than are able to survive
2 there are difference in appearance of traits found in
individuals of the species or organisms of the same
species look different from each other
3 Natural Selection is the mechanism for how
evolution works.
36. Natural Selection Notes
Darwin‟s Theory of Natural Selection
4 In a specific environment, some traits will help with
survival and reproduction (fitness) more than others
5 Over generations, the population will change to
have more traits that help survival and reproduction
37. Natural Selection Notes
Jean-Baptiste Lamarck – contemporary of Darwin
who proposed an alternate theory of evolution.
Thought that organisms strived to be more perfectly
suited to their environment
38. Natural Selection Notes
Remember (aka Key Points)
A population is the smallest unit that can evolve.
Individuals CAN NOT evolve
Natural Selection diminishes (decreases) or amplifies
(increases) existing traits
Natural Selection depends on environment
39. Natural Selection Notes
Why is diversity important in a population?
Increases the likelihood of a species surviving during
environmental changes.
42. Warm up
Turn in Introduction to inbox or email the assignment to
me. If you already turned it in, that‟s fine.
Take out a sheet of paper and title it evidence for
evolution. This will be your notes for evidence for
evolution.
ANNOUNCEMENT: Treekiller ran out of toner. Please
print out work on Chainsaw
43. Evolution Choice
Evidence for Evolution
Watch Darwin‟s Dangerous Idea Video: List the
evidence he provides for evolution.
44. Lab
You can work alone or in groups of 2-3
Finding Homologous Structures Lab
Title: Homologous Structures Lab
Purpose: To find homologous structures in the same
phylum
Method: Compare 2 organisms from the same phylum.
Sketch the organisms you are comparing. Label the
phylum and the name of the organisms. Look for
homologous structures and different structure and list
them. (You only need to compare organisms from 6
phylums out of the 9)
Results
Conclusion: Are organism in the same phylum more similar
that those from a different phylum? Why or why not?
