A few comments on photovoltaics (solar cells)
Solar Cells: one path to sustainable energy
. . . also called "photovoltaic" (PV) energy
. . . Some images:

http://www.metaefficient.com/architecture-and-building/skyscraper-gets-covered-in-7000-solar-panels.html
What is the future of PV, etc.?
. . . First, the "etc.": http://blog.ted.com/2009/06/02/announcing_sing/
. . . Next, lets focus on the PV graph
. . . . . . curve fitting a straight line gives the slope
. . . . . . what is the slope? See hard copies
. . . . . . let's "Delphi it"!
Types of PV technology
. . . Example technological advance
. . . . . . Cost reduction approach: vacuum typically needed to deposit top layer of anti-reflective material, vacuum processing is expensive, spray-on technology is cheaper and under development
. . . . . . Thin film vs. regular
. . . Efficiency improvement (are these exponential?)

. . . . . . http://www.tf.uni-kiel.de/matwis/amat/semi_en/kap_3/illustr/eta_development.gif
For general information on PV see: http://www.pveducation.org/pvcdrom
A major tipping point: grid parity
. . . check some graphs: see
. . . . . . image.google.com (query: grid parity)
Exercise: using a hard copy of Kurzweil's graph, figure out when PV will satisfy 100% of energy needs
. . . Assume world uses 15,000,000 (15 million) megawatts (per http://en.wikipedia.org/wiki/World_energy_resources_and_consumption)
. . . . . . Note: for simplicity, you may assume 10,000,000 if you wish
. . . Assume continued exponential growth
. . . . . . (straight line on log graph)
. . . Ok that's the mathematical result, but what do you think will really happen?
. . . . . . Why?

Oil: the Hubbert peak
Today: the Hubbert Peak
1. Who was Hubbert?
. . . Marion King Hubbert
(Oct. 5, 1903 – Oct. 11, 1989)
. . . Was a geologist at Shell
. . . Devised a way to predict
oil production for a given oil field
. . .and by extension for a given country
2. ...and what was his peak?
Oil field production rises,
then hits a limit,
then falls
Duh!
But why does it rise? Level off? Fall?
The qualitative observation is obvious
Quantifying it (to allow predictions) is trickier
3. Hubbert's prediction about the US
. . . in 1956 he predicted:
US oil production would peak in 1965-1970
. . . he was widely disbelieved
. . . but US production did peak in 1970
. . . sure we still pump the stuff
but less, year by year
4. Other countries and their Hubbert Peaks
. . . Each country has its own peak
. . . Most countries have peaked already!
. . . Some major oil-producting countries have not
. . . Iraq, Iran are among them
5. If fields and countries peak,
why not the whole world too?
Suppose one country's production is increasing . . .
can world production be decreasing?
. . . How is the world different
from any one country or oil field?
6. Why the world is a bit different
. . . price elasticity of oil:
or not very elastic?
So are oil prices elastic or not?
7. How sensitive are oil prices
to changes in production?
. . . for a field?
. . . for a country?
. . . for the world?
8. Ok, so...
How sensitive is production
to changes in price?
. . . how might
the world peak of production
differ from
a countries peak of production?
9. Example: pre-recession gas prices
When will the peak be?
. . . http://www.hubbertpeak.com/images/peakoilproduction2008.png
or, better, just
http://www.hubbertpeak.com/
. . . Inference:
as recession eases,
gas prices will skyrocket
... again
. . .Inference #2:
getting new wheels soon?
Avoid a gas guzzler...
. . . When will be a better time than now
to go for a power & performance oriented car?
Btw: Hubbert-style peaks apply to other resources
. . . renewable, non-renewable, or both?

Homework 14
1) Check out the Leonid shower tonight, if the sky happens to be clear enough to catch something interesting. The general direction to look is the constellation Leo, which may be in the general direction of Northeast. You don't have to be able to recognize Leo because the meteors will be spread out over a fair area. If this seems unrealistic, then find 2 videos of the Leonid shower (at least, to include at least one that you would consider "worth it to have checked out"), or some other planet, moon, or other astronomical phenomenon. (a) Describe. (b) Then relate to the concept of colonization somehow. Or if you prefer, discuss colonization in the context of some other planet, moon, part of the Earth, etc.
2) Term projects - if you do not know when your presentation is, let me know. Work more on it...the closer you get to finishing it, the better off you'll be! Post new material on your blog. Also, start preparing your presentation. One way to do that is to use your project writeup as a guide, and make slides that will step us all through it (just a suggestion).
Backup plan for homo sapiens: space adventure
. . . It will be passed around
. . . Here is how to use it
Meteors
. . . Terminology: meteoroid, meteor, meteorite
(and asteroid, comet, micrometeoroid, cosmic dust, etc.)
. . . Anyone ever see a shooting star?
. . . "The wonders of the universe!"
. . . Video: shooting star, satellites, ufo
. . . 3-second video of shooting star
How to protect against:
. . . supervolcanoes (cradle of humanity?)
. . . asteroid impacts (death to dinosaurs?)
. . . nuclear war (death wish?)
. . . runaway greenhouse effect (like Venus?)
. . . ozone layer destruction (we're winning this one?)
. . . stealth virus (wouldn't happen naturally?)
. . . nano-goo (not serious?)
. . . nearby supernova (unlikely?)
. . . Etc.?
Eco-bubbles
. . . self-sufficient communities in bubbles
. . . lava tubes are often recommended as easier
. . . could be on the moon
. . . maybe Mars
. . . maybe Earth (deserts, Antarctica, oceans, or anywhere)
. . . maybe on an asteroid or floating in space
. . . maybe other planets, moons, etc.
. . . each one is a backup plan for the species
Eco-bubbles are colonies
. . . They're a lot easier if decent conditions are outside
. . . What conditions are needed?
. . . water (at least O and H)
. . . sunlight
. . . carbon dioxide for plants (at least C)
. . . nearness to Earth
. . . temperature issues
. . . a little of nitrogen compounds (at least N)
. . . energy (e.g. light, solar cells)
. . . some of these are easier to compromise on than others
. . . . . . like what?
. . . We've heard about the moon & Mars
. . . What about others, like Mercury, Venus, Titan, many others?
Water
. . . It's on the moon!
. . . See video, etc.
. . . It's on Mars!
. . . It's even on Titan
. . . . . . Where's that?
. . . . . . Titan BBC segment, http://www.youtube.com/watch?v=SplxlPbKc3Y
. . . . . . http://saturn.jpl.nasa.gov/multimedia/flash/Titan/index.html
. . . . . . http://science.nasa.gov/headlines/y2005/16jan_titan.htm
. . . . . . BBC again, http://www.esa.int/SPECIALS/Cassini-Huygens/SEM85Q71Y3E_0.html
. . . . . . Another one, http://www.youtube.com/watch?v=YJ0hwTzOMPE&NR=1&feature=fvwp
Imagine Mars (or the moon, etc.)
. . . dotted with bubbles
. . . covered with bubbles?
. . . if a colony is started,
. . . . . . it will grow
. . . . . . new bubbles will have to be built
. . . . . . eventually, the entire new world will be overpopulated
. . . . . . how long will that take?
(We discussed that earlier:
What was the take-home message?)
. . . . . . let's say Mars, for example
. . . . . . how long do you think it will take?
. . . . . . we could try a Delphi approach...
. . . . . . let's try it with spreadsheets
. . . . . . . . . the power of information processing!
. . . . . . what if we vary rate of increase?
. . . . . . initial colony size?
. . . . . . population capacity of the new world?
. . . . . . let's vary one or two, use Delphi, then spreadsheets...
. . . . . . we might graph time-to-overpopulation vs.
. . . . . . . . . rate of increase
. . . . . . . . . initial size
. . . . . . . . . population capacity
From "The Million-Year Picnic," in The Martian Chronicles, by Ray Bradbury, 1950
Setting: Mars, after Earth is destroyed in a nuclear war.
"Now I'm going to show you the Martians," said Dad.
...
They reached the canal. It was long and straight and cool and wet and reflective in the night.
"I've always wanted to see a Martian," said Michael. "Where are they, Dad? You promised."
"There they are," said Dad, and...pointed straight down.
The Martians were there - in the canal - reflected in the water.
The Martians stared back up at them for a long, long, silent time from the rippling water.

Homework 12
1) Recall the relevant class. Comment on Toxoplasma Gondii. What do you think??
2) Add more to your project or project presentation. Put the new things in a new blog posting or email it. Consider new material that has some connection to Toxoplasma Gondii. Alternatively, it could have a connection to some other parasite or disease, or parasites or diseases more generally. Or it might be about something completely different...your choice!
3) This course has been designated as able to help keep our curriculum accredited! Therefore we need to ask students to answer certain questions. This week's question is:
Think about the impact of information and/or computing privacy, security, and quality, etc. on individuals like you. Then explain what these conclusions mean for society as a whole now and in the future, as follows.
a) privacy
b) security
c) quality
d) some other one of your choice

1) Suppose you had a coupon for a free robot. The catch is it can only do one thing. But you can get a robot that will do whatever one thing you like, just not anything else. What would you want your robot to do?
2) Write or develop an additional significant piece of your project. As a suggestion, consider the connection of robots to your topic. However, if another subject besides robots seems more appropriate, that is just as good. Post the new section on your blog.

- (per IEEE 1621)
Power LED
- LED?
- green=charged
- amber=partial charge
- red=little charge
- flashing red=no charge
- What is the charge of yours?
Play button
Play LED
Advance button
Advance LED
Resetting the robot:
- Power cycle it. Try it.
Choosing a demo (10 of'em)
- Press the 'Advance' button
- Printed with a double arrow
- 4 beeps for demo #4
- long beep for #5
- long + 2 shorts for #9
- How about #10?
Try each demo outside where there is more room...
Contact points for home base
- Why not save $ by making them out of plastic?
Cliff sensors
- Are these spring-loaded feelers, or electronic?
Battery
- Take it out
- Put it back in

Musical robots
send:
128 132 (start, then put robot in full programmer control mode)
send: 140 0 4 62 12 68 12 69 12 74 36
(loads a song)
send:
141 0
(plays the song)
140=defines a song
0=name it song #0
4=we'll see later :)
62=MIDI note #62 (range 31-127)
12=twelve 64ths of a second
Etc.
You can send all three at once:
128 132 140 0 4 62 12 66 12 69 12 74 36 141 0
Notice the 68 is a 66 this time
Should give you control, then load, then play the new song
Try some variations on
128 132
140 0 4 62 12 68 12 69 12 74 36
141 0
recalling that:
140=defines a song
0=name it song #0
4=song has four notes
62=MIDI note #62 (range 31-127)
12=twelve 64ths of a second
Etc.
Insert a 5th, superhigh tone, 111
Play it for a long time, 100:
128 132
140 0 5 62 12 68 12 69 12 74 36 111 100
141 0
Try it
Program new variations and let's have a concert...
Robot motion
Moving - kind of key for robots!
Initialize: send
128 131
Make it move:
be ready to pick up so it doesn't fall
send :
137 0 100 128 0
137=drive
0 100=go 100 mm/sec
128 0=go straight, no circle
Notice that:
128 131
is not the same as
128 132
which gives full control
This time try
128 132 (instead of 128 131)
Then again make it move (be ready to pick it up!):
137 0 100 128 0
Pick it up
Now what to do??!
Change the initialization back to:
128 131
and send it
What is the slowest speed you can get it to go?
Scripts
A kind of small program
152 17 137 0 44 128 0 156 0 144 137 0 44 0 1 157 0 90 153
Let's analyze it!
152=define a script
17=it has 17 more bytes
137 0 44 128 0=drive, 0+44=44 mm/sec., 128 0=straight
(137 1 44 128 0 would drive 256+44=300 mm/sec.)
156 0 144=wait until 0+144=144 mm
137 0 44 0 1=drive, 0+44=44 mm/sec., 0 1=spin counterclockwise
157 0 90=wait until 0+90=90 degrees
153=repeat script
Notice how this makes it go in a rectangle!
To run the script:
send 128 131 (start in safe mode)
send 152 17 137 0 44 128 0 156 0 144 137 0 44 0 1 157 0 90 153
send 153 (to run it)
Recall:
152=define a script
153=play a script
Well,
154=show the script
try it
what happens?
Let's review the script program...
Then try variations on the program
- see board for command details
If time allows - show off your new program

Robot Bible
The Robots’ Bible
Robogenesis
In the beginning, humankind created visions, and reality. Now the reality was unformed and void, and darkness was upon the face of *robotics*. And the spirit of humankind hovered over reality. And humankind said, let there be electricity, and there was electricity. And humankind saw the electricity, and that it was good. And humankind divided electrification from non-electrification. And humankind called the electrification "progress," and the non-electrification was called "Luddism." And there was bright evening, and bright morning, one day.
[...]
And humankind said, Let robotics be gathered together into an academic discipline, and let conferences; contests; benchmarks; and journals appear. And it was so. [...] And humankind said, Let robotics put forth mobile robots, robots yielding manufactured products, and robots that build more robots after their kind, whereinare the plans thereof, upon the robotics endeavor. And it was so. And robotics brought forth Web and desert rovers, manufacturing robots, and robots that build robots, wherein are the plans thereof; and humankind saw that it was good. And there was dreaming andawakening, a third day.
[...]
And humankind said, Let reality swarm with swarms of living robots, and let fly in the heavens, even unto Mars. And humankind created the great robotic ships, and every living robot that creepeth upon the floor, wherewith reality swarmed, after its kind, and every flying robot after its kind; and humankind saw that it was good. And humankind blessed them, saying: Be fruitful, and multiply, and fill reality and the imagination. And there was vision and there was the hidden hand of economics, a fifth day.
And humankind said: Let reality bring forth the living robot after its kind, workerbots, and floor-cleaning robots, and agribots after its kind. And it was so. And humankind made agribots after its kind, and workerbots after their kind, and every robot that creepeth upon the floor after its kind; and humankind saw that it was good.And humankind said, Let us make Turing robots in our image, after our likeness; and let them have dominion over the robotics field, and over the flying robots, and over the workerbots, and over all reality, and over every creeping thing that creepeth within reality. And humankind created robots in their own image, in the image of humankind created they them, with the ability to build progeny better than themselves they createdthem. And humankind blessed them, and humankind said unto them: Be fruitful, and multiply, and replenish the earth, and *subdue* it; and have *dominion* over the robotics field, and over the flying robots, and over every *living thing* that creepeth within reality. And humankind said: Behold, we have given you everyresource, which is upon the face of all reality, and every renewable, in which is the capacity for renewal - to you it shall be for production of more robots [...]. And it was so. And humankind saw every thing that they had made, and behold, it was very good. And there was singularity and there was post-singularity, the sixth age.
And the vision and the reality were finished, and all the host of them. And in the seventh era humankind finished their work they had made; and humankind rested in the seventh era from all their work which they had made. And humankind blessed the seventh era, and hallowed it; because in it they rested forever from all their work which humankind in creating had made.

Prediction vs. Intervention; Weather vs. Climate
Observation #1:
. . . Does Fall semester feel different from Spring semester?
Observation #2:
. . . My lab was involved in an interesting weather research project
. . . Later, let's discuss if the results apply to climate...
Predicting the Weather
Remember "Spoil Sports of the Prediction Game"?
. . . That's why weather forecasters have a bad reputation
. . . . . . It's not their fault!
. . . . . . They're doing the best they can
. . . They often do okay short term
. . . . . . We'll never predict the weather on this date next year
. . . . . . Delphi method: how far in advance do you think we'll get?
What about weather control?
. . . Like here in the US in, say...
. . . . . . Minneapolis (straight north of Little Rock)
. . . . . . Buffalo (lots of Great Lakes-related snow)
. . . . . . etc.
. . . Little Rock -
. . . . . . Snow equipment costs a bundle, hardly ever needed
. . . . . . Cheaper just to shut down the city
. . . . . . . . . That's expensive too (but at least you get an extra vacation day!)
Moscow has

The Russian Air Force plans to spray clouds with liquid nitrogen, silver (iodide?), and cement
. . . see news article link under image above
Interestingly, you can buy weather modification equipment
. . . http://www.nawcinc.com/photos.html
. . . How well it works is another issue...
What's easier, predicting or controlling weather?
. . . What would you guess?
About research from my lab
. . . Experiments done by former grad student Dongping Xu
. . . . . . as-yet unpublished research
We asked:
What predictions are more reliable:
Forecasting the weather?
-or-
Forecasting the effects of weather modifications?
How we answered
1. Predict the weather using MM5 on given initial weather pattern
2. Add a bug to MM5, run it again
. . . what is a bug?
Source: http://en.wikipedia.org/wiki/File:H96566k.jpg, in http://en.wikipedia.org/wiki/Software_bug
3. Do this for many different bugs
4. Calculate the average amount of change caused by a bug
. . . that is, change to some quantitative weather value
Why care about how MM5 acts when bugs are added?
Now do another experiment
(Delta is a Greek letter that is a triangle)

Trend Analysis
Consider the graph below
Suppose this graph shows a fact about how bar height changes as we proceed rightward
Suppose further the data are noisy
What do we mean by "noise"?
We want to shrewdly determine the fact by mentally discounting the noise
Without giving any hints to your neighbors...
Take another look, then decide on the mostly likely fact:
a) Height decreases the farther right we go
b) Height starts out at a high plateau on the left, then switches to a low plateau as we move rightward
c) Height decreases at first, then increases ("U" curve) as we move rightward
d) Height increases as we move rightward
e) Cannot tell from the given data
Discussion?

Homework 10
Suggestion: answer Q1 soon, while things are still relatively fresh in your mind. At least, figure out the answer for writing down later (that's actually better because then you have to think of the answer twice!)
Q1) We discussed in class how there is no such thing as a "scientific proof." Explain in your own words.
Q2) Write a new part for your project of 250 words or more.
Earth 2100 continued
Some initial comments and questions before the general discussion
What is the difference between science and mathematics?
Math: prove new things based on existing knowledge
Mathematical reasoning is deductive
- 1+1=2
- 2+2=4
- Therefore, 1+1+1+1=4 (proof by substitution)
- All men are mortal
- Socrates is a man
- Therefore, Socrates is mortal (proof by "syllogism")
- Deduction can prove things
- Mathematics uses deduction
- Therefore, mathematics can prove things
- . . . . . . (proof by syllogism again!)
Science is different from math!
- Science is based on induction (not deduction)
- All apples observed to break off the tree, fall down
- Therefore, if I shake this apple tree and an apple breaks off, it will fall down
- Not a proof! Can you think of a counterexample?
- That which goes up has always come down
- Therefore, if I throw this up, it will come down
- Not a proof! Can you think of a counterexample?
Science needs more than only induction
Humankind has always sought reasons
Scientists call those reasons "theories" and "hypotheses"
Theories are the big ones
- relativity
- evolution
- continental drift/plate tectonics
- If the ground gets waterlogged, water will get into my basement
- IFSC majors learn more marketable things than physics majors
Math proves; science does not prove!
Science explains (using theories)
Science predicts (because the theories predict)
The phrase "scientific proof" makes no sense!
- Science does not prove things!
- It explains things and finds evidence
- If only everyone actually knew that
- Like reporters, spokespeople, politicians...
. . . Worst case scenario consistent with best science available
. . . The main crises were global warming and deadly disease
. . . . . . So it could happen that bad, but might not
Climate science uses theories
implemented as complex
computerized models
- There are variations among different models
- They make somewhat varying global warming predictions
- Global warming is happening, will get worse, and is a serious problem
- That is the consensus among climate scientists
- Just no math-style proof
Politics and special interests are a different ball game
. . . Some economic interests benefit most if nothing is done
. . . . . . Naturally, they will impede change
. . . . . . . . . That is famous economist Adam Smith's "Invisible Hand"
Your turn: Earth 2100 discussion
Please have your say and let everyone else have theirs!
I reserve the right to take an active role in organizing the discussion.
What technologies are envisioned and what are their plausibilities?
- We live in Arkansas, which is in the United States, we are Americans and speak English
- Some people live in Holland - what is the elevation in Holland, what country is it in, what is the nationality of its people, and what language do they speak?
Ever see the doors of the lock of the Big Dam Bridge?
What is the connection between epidemics and global warming?
- Any diseases already spread to the US?
- Any that may soon?
- Long-term blackouts
- Transportation network breakdown
- Where would you want to live if things went bad?
- How about Arkansas?
- Little Rock?
Hyperpowers are historically limited in time
- Mongolia
- Rome
- UK
- US
But how to stay that way?
What are the natural tendencies that cause hyperpowers to be time-limited?
- Rigidity
- Over-confidence from past successes
- Inner rot
What can be done to prevent it or delay the inevitable?
Why successful societies collapse
Earth 2100 quotes someone asking what the person who cut down the last palm tree on Easter Island could have been thinking
That is straight out of Diamond's book
Diamond appeared several times in the movie!
Easter Island, Rome, the Anasazi, the Mayans, the Greenland Norse, ...

Homework 9
Recall HW 7, where you assembled information about your project, developed an outline, etc. Let's continue the development process some more.
1) In a new posting on your blog, post your current writeup. Add notes inside it in various places. Each note says what you would like to add in at the location of the note. If you are writing a story, this might not work - instead, just add some more material to it, or develop more plot description, or whatever advance seems best.
2) Write and incorporate a new part. Ideally it should be about crime (or precrime!), or indeed any other idea from Minority Report or our discussion of it. But if that doesn't fit, any other advance to your project will do just as well.
3) Write and incorporate another new part. Ideally it should be about cyborgs, mind hacking, ghosts, shells, ghosts in shells, therm-optic camouflage, or something else related to The Ghost in the Shell. But again, any advance to your project will be fine.
4) Explain briefly what you did for questions 1), 2), and 3) so that I can decipher what you did for this HW.

Homework 8
1) (Due this Wednesday before class) Post, on your blog, 250 words or more commenting on "Minority Report." This will get you thinking so we can have a more in-depth discussion. You can discuss any aspect of it you like - here are a few suggestions to get you started.
- Could this really happen?
- What could really happen?
- What if they found genes that make it more likely for someone to commit a crime - what should they do?
- What is the movie "really" about? For example, Orwell's book Animal Farm was really not about animals, but about communism, and Russia (then the Soviet Union) in particular. You can have a story about cats that's really about dogs, etc.
- What themes found in other movies and stories or in the popular imagination are present?
- What methods and tricks does the movie use to make the audience like it?
- Speaking of precrime - http://www.cnn.com/2009/TECH/10/06/security.screening/index.html. (And what about racial profiling? Any kind of "profiling"? Differential insurance rates? Is a definite future illness a "preexisting condition"? Measure testosterone levels, which predict criminality? Eugenics? Young men commit the most crimes - put'em all away? See http://www3.interscience.wiley.com/journal/119317165/abstract?CRETRY=1&SRETRY=0.)
