Shearing time: Let's go hyper-local Arizona

The original post of this name and URL was written in 2010. My 2026 update begins at the "Click here for more" jump.

It's that time of year again. In September, Navajo sheep herders start coming down from the mountains north of Valley of the Sun. I hope they're psychologically well-prepared for news of the big city:

  • a broken dam due to burst bladders at Tempe Town Lake ("bladders"?)
  • $1,000,000 price on the head of Maricopa County's Sheriff Joe by the usual Mexican cartels/drug lords
  • the ever popular (no, not really, only to me and Sheriff Joe Arpaio!) Arizona Senate Bill 1070, also known as Arizona Immigration Reform.

To commemorate shearing season, this post provides an extravaganza of gentle sheepy imagery, from varied sources. Well, I admit, from two sources: a Zazzle merchant and Amazon.com. The images were so nice, I thought you might enjoy looking at them too.

Hmm... I need to find a better source for illustrations than re-purposed advertisement images, especially since I don't participate in any online ad program. I'm definitely not a Zazzle or Amazon-affiliate website.

Vibe coding an IQ test using GPT5

The purpose of IQ tests is to measure cognitive ability NOT knowledge per se. Education should not be about memorizing test answers (even though it often is). The idea of IQ test prep is even worse, as it defeats the entire purpose of psychometrics; yet evidence of efforts to increase one's IQ are everywhere  online. Sometimes, it is unclear whether the goal is increasing intelligence, or just getting better IQ test results! 

After a brief peek into this world, I found myself taking a timed online IQ test developed by GPT5.

reddit brain training

reddit offers multiple subreddits for users who are intent on increasing their IQs. First, I read this morose post in r/cognitiveTesting: I took mensa's online IQ test and got 95 despite thinking all my life that Im smart: (make some allowance for English as a second language... maybe?)

Throughout all my life, I was told i was intelligent and my relatively low grades didnt reflect poor cognition but rather, laziness. In secondary school... I was painfully mediocre, bordeline on below average, though teachers said ''if you specifically study more, you'd excel'' And always coped by saying ''its because im lazy, not because im dumb;;

In reality, i was both.

Dont know how i managed to get into a good uni. At uni, Im not the perfect student and Im a bit dissatisfied that study isnt easy.  I just wish I was more intelligent

I know its mostly biological, but can i naturally increase my IQ?

redditor Yonderboy responded:
Look up quad n-back (QNB). I can’t vouch for it personally, and most people will tell you it’s not possible (without ever having tried it), but there are a few cases of people dramatically improving test scores, school performance, and subjective feelings of cognitive ability after very prolonged (> 6 months) and regular (> 3.5h/wk) QNB training.

What is N-back training?

N-back tasks are often used in psychology and cognitive neuroscience assessments to measure working memory. The n-back task consists of reading a series of letters to the test subject. The subject indicates whenever a letter repeats some number of letters previously. The n in n-back is the number of letters. n = 3 is typical.

Some redditors and, admittedly other, less unhappy people, enjoy doing n-back tasks as a game. The IQ test redditors are interested in them as a means for improving memory, memory capacity, and increasing fluid intelligence. There is scant, if any, evidence that n-back "training" has any such beneficial effects.

Dual n-back is when two n-back tasks (e.g. one auditory and one visual) are administered simultaneously. Of course, there is a subreddit devoted to that, r/DualnBack. It is easy to misread it as Dual In Back. Multiple phone apps are available for dual n-back enthusiasts.

Rare and amusing Saturday Night Live satire of Democrats

It was near the finale of the 2024 U.S. Presidential campaigning. On the last weekend before the general election, Saturday Night Live satirized the media's penchant for the Democratic National Party; or perhaps, the GOP's allegations of such.  

I was delighted that the episode included a faux David Muir, whom I perceive as a thinly-veiled version of MSNBC's Rachael Maddow. (Muir does manage to maintains his composure and admittedly, Rachael's show is intended as commentary not reporting.)  The real Muir's news delivery has a distinctive "the world is ending!" tone, which isn't modulated by the gravity, or relative lack thereof, of the content he reports. I'm not a media professional nor even much of aa viewer, so I was delighted that at least one other person, the ersatz SNL Muir parodied real Muir's genuine anchorman voice with an edge of hysteria!  

A faux Minnesota governor Tim Waltz made multiple appearances. He professed his love of fried foods and dislike for anything spicier than a tomato. 

This doesn't happen very often

The real then-Vice President and DNC general election candidate Kamala Harris made a cameo appearance toward the end. Her SNL counterpart was great, so much so, that the opening of SNL made me laugh outright!


If you pan out, they look remarkably like the real thing. 

SNL viewer reactions

Plenty of people; i.e. the masses including me; were watching by time-delay via YouTube. There were many expressions of grief and anger in the comments. Did I already mention the extreme antipathy toward Donald Trump, regularly on display in his first term?    

In case you've forgotten, or are still trying to forget, Joe Biden had an unsettling tendency to smell women's and young ladies hair.  While visiting YouTube, I realized that this should have been well-known long before Biden's tenure as  President of the United States. 

I found a very brief clip of former U.S. Attorney General Jeff Sessions. He is being vigilant, shooing Joe Biden away, preventing the VP's attempt to sniff the hair of Sessions' very young granddaughter.  Democrats didn't like Sessions. They didn't like the government waste and corruption that he acted against either



Government opacity or corruption

Sessions was appointed to lead the Department of Justice during the Trump 1.0 administration. He held the position of Attorney General for less than two years. I'm still impressed with one of his lesser-known accomplishments, in support of victim and taxpayer justice.

Beautiful B-2 Spirit and not-so-beautiful DoD testimony

Let's look at pictures first, before getting into the nitty gritty of U.S. Air Force project management.

Putting a B-2 through its paces at 90° North

This is a beautiful photo of a beautiful B-2 Spirit approaching the North Pole.

Testing B-2 performance at a
geomagnetic extreme point 

The US Air Force provides some details about this test flight:

A B-2 Spirit flies to the North Pole on October 27, 2011, on a test mission from Edwards Air Force Base, California. The polar flight helped ensure that the B-2 maintains its combat capability in all environments...

The North Pole's coordinates are 90° North latitude and 0° East or 0° West longitude, take your pick. (For the sake of notational accuracy, it is usually expressed as 90° North but disregard that for the moment.) Patience, please, as I am going somewhere with this.

So, 90°N 0°E is merely a "quarter" rotation of the Earth away from coordinates of  0°N 0°E according to the map projection of the World Geodetic System 1984. WGS84 is an often used global reference system for modeling the Earth. The U.S. Department of Defense and GPS (Global Positioning System) both use WGS84. 

Notably, the DoD developed GPS AND made it freely available to all in the early 1980s.

Null Island is L0L0

If one is doing geocoding with GPS and WGS84, the Library of Congress describes 0°N 0°E as 

"a curious blend of real and imaginary geography, of mathematical certainty and pure fantasy"

Looking backward: Shifting U.S. allegiances in the Middle East

This is a two-page excerpt from a book titled Muslims in Europe: Notes, Comments, Questions by Manfred Wolf, PhD. It comprises several dozen essays, written over the span of a decade. 

I found the following brief section from "Muslims in Europe" of interest because Wolf wrote it in 2015. He had had a run of accurate short-term geopolitical predictions. I was sufficiently impressed, as I read with the benefit of hindsight, to give his longer term prognostications some consideration. 

Some background about the scholar

After 40 or so years as a professor of English literature at San Francisco State University, Manfred Wolf worked part-time as a faculty member at the University of California at Berkeley, teaching Dutch language and literature. 

Wolf also wrote an autobiography of his early life, titled Survival in Paradise.. It details his and his family's journey from pre-WW2 Germany to the Netherlands. A happy childhood was soon interrupted by abrupt departure--as Nazi Germany invaded western Europe--transiting through France to Portugal, then travel by ship across the Atlantic, and finally, adolescence in the Dutch Antilles in Curacao. For many years, Wolf wrote a column in a San Francisco weekly newspaper and many other non-fiction works and literary articles. "Muslims in Europe" is self-published. Wolf is not what I would consider a professional author, although he is a very fine writer!

Be aware that Manfred Wolf was about 80 years old in 2015. He is a liberal non-observant Jew, maybe leftist in his youth, who probably voted Democrat, up and down ballot, for all his years as a naturalized American citizen. He seems to possess a greater propensity for supporting exercise of First Amendment rights than many people of that demographic.

Less background about me

Manfred Wolf is the father of my former boyfriend and fiance of many years ago, Michael Wolf. 

EDIT: The website for Manfred Wolf's autobiography, Survival in Paradise is apparently defunct. Perhaps it was due to expire as of 31 Dec 2025. 

The last paragraph of interview of Wolf about the book included Michael's insightful question about his father's trek; I had wondered the same thing for many years. It is rather serendipitous to discover the answer today! Sadly, it is all gone now, but I recall the intent of Michael's (the son's) question and his answer!

To my enduring regret, I broke my engagement with Michael.

OMG Immigration police seen detaining people denied asylum

Deporting illegal aliens

U.S. Customs Enforcement and Immigration officers are caught by the local Phoenix affiliate of ABC News, ABC15, in the act of DOING THEIR JOB! Just look at what is going on in downtown Phoenix today.

This is a Breaking News report. According to the ABC15 live action reporter,

Our crews at the scene on Wednesday morning saw agents waiting outside and detaining people as they exited the building. ABC15 spoke with a few of the people who were being placed in vans, who said they initially came to the courthouse for asylum cases, which they say were then dismissed.

Is case dismissed a good outcome? 

The reporter asked questions of two women being assisted to their seats in one of the white vans. Through the assistance of a Spanish interpreter, both said that they had gone to court for hearings of their request for asylum cases; the immigration judge had "dismissed" both cases. One woman was from Venezuela, another from Mexico. 

Asylum hearings are not like civil lawsuits or non-immigration related criminal charges!  Dismissal of a lawsuit or criminal indictment would be a GOOD thing for a defendant. Dismissal of a request for asylum would NOT be a good thing for an asylum seeker. If dismissal were the outcome of these immigration court hearings, then arrest and deportation would follow. 

ABC15 doesn't seem to realize this, as they "reached out to officials to find out why people were being detained or arrested".

Asylum as shortcut to migration

The consequences of illegal entry (i.e. deportation) are held in abeyance if one claims to be seeking asylum in the U.S. Until the presidential administrations of Obama or maybe, G.W. Bush, this sort of asylum seeking was rare, and mostly sought by citizens of Warsaw Pact countries during the Cold War. 

As of 2018, an estimated 11 million illegal aliens resided in the U.S. including the Obama-declared DACA aka Dreamers. Between 10 and 20 million asylum seekers joined them during the four years of Joe Biden's presidency. Be aware that the entire U.S. population is about 330 million men, women, and children. 

11 + 15 = 26 million illegal non-citizens residing in our country means that 7.9% of the people in our country lack legal status.

Plane malfunction illusion: Rolling shutter effect

Chris wanted to take a photo while on an airplane flight. The aircraft was a Bombardier Q400. Chris didn't have a camera with him, only his Apple iPhone 3GS. The scanning order of his iPhone sensor combined with the light refracted from the airplane window caused a distinctive "detaching blades" phenomenon in the photo. Rotating the camera warps the blades in different directions.

Edit: Unfortunately for me, Chris is no longer sharing his photos online, but I have found others. Keep reading!

Bombardier Q400 digression

There have been some serious safety concerns with the Bombardier Dash Q400 Turboprop. Persistent problems with faulty landing gear received plenty of media coverage. Also, landing gear failure is highly noticeable to passengers! Some of the worry is depicted by The Cranky Flyer in the little drawing.

Although there have been no passenger injuries, thanks to pilot skill, multiple instances of left or right wheels failing to extend fully (or at all!) upon landing have occurred in Canada, the United States, and France. Those are the markets for Bombardier's small-to-medium sized commercial and business aircraft.

Engine stalls in very cold weather, due to ice, is another issue with the Q400. Both the U.S. Federal Aviation Administration (FAA) and Canadian air safety regulators launched formal inquiries.

Despite the appearance of Jason's photo below, there have never been any problems with Q400 propellers blades detaching and falling off while in flight!

Decline of Web 2.0

In a prior post, I wrote about a whimsical 1870s era cartographic depiction of America as a Young Hog. The source publication from which I first learned of it, University of Michigan's Map Library blog, has since been discontinued. I shouldn't be surprised, even though it makes me feel sad.

Web 2.0 is user-contributed content

Blogs, Huffington Post and Forbes per-pageview paid contributors, BuzzFeed, Second Life, YouTube, image sharing services, question-and-answer sites, and comment sections (for online newspapers as well as blogs) are examples of user-created online content. It is difficult to believe that Technorati tracked millions of active blogs at one point in time. User-contributed content sites seem to have been in decline for years.

Technorati was considered an authoritative source for blog activity. It was before my time, but sounded great, even including a blog search engine that was superior to Google's blog search. Google Blog Search vanished years ago, like many Google services.

Blog growth outpaces Moore's Law?!

That's what Technorati claimed in 2005: Blog growth was frequently doubling. The BBC seemed VERY excited about Technorati, and blogging in general, see "A new blog created every second"! Even though the dot com bubble was years earlier, there was still a lot of Internet hype then.

In August 2005, Technorati was tracking 14.2 million blogs, up from 7.8 million in March of the same year, according to the BBC. New blog count was doubling every six months! That's analogous to the real Moore's Law, applicable to technology, not blogs. 

Moore's Law isn't a law of physical science, but rather, a rule of thumb based on the observation that semiconductor processor speeds double every six months. (Moore's Law hasn't held up so well due to the physical limitations: there are only so many nanometers of room on processor chips.)  There's more to read about Moore's Law here including a link to Gordon Moore's original article about it.

With such amazing growth, it wouldn't be long before blogs outnumbered Earth's adult population!

Make America Porcine Again

Years ago, I found a post on the University of Michigan's Map Library blog. I consider it evergreen, as it is about two of my favorite things: Piggies and cartography!  Now seems like a good time to write about it. After all, maps were the safest way to travel during the COVID19 pandemic. Old maps even allow one to travel in time, with sufficient imagination.

In lieu of the Map Library blog, I turned to Big Think's Strange Maps. I located this excellent post, National Porcineographic: Portrait of America as a Young Hog.

Helping humans by helping pigs

William E. Baker was a 19th century tailor. He made his fortune thanks to a strategic alliance with what became the Grover & Baker Sewing Machine Company. (It was later acquired by Singer Sewing Machines.) Baker's philanthropy was extensive, but centered on his Hygienic Farming and Sanitary Cookery initiative. He wanted to improve human health by helping pigs.

Unvirtuous circle: Boston was a cesspool

New England rapidly industrialized, and the population grew along with it. An ecosystem evolved but it was of a distinctly pragmatic sort. The City of Boston instituted a garbage pick-up service but then disposed of the garbage anywhere and everywhere possible. Typical locations for garbage dumping were on the outskirts of the city or in neighboring communities. It was NOT environmentally friendly! Town and nearby country dwellers developed a recycling response: They fed the garbage to pigs.

W.E. Baker believed that this practice was the cause of much disease, in both swine and the people who consumed unwholesome pork. In 1875, he introduced a 'Sanitary Piggery' in rural Massachusetts. It was the cornerstone of Baker's contribution to the pure food movement.

"Baker’s Sanitary Piggery involved a clean environment and wholesome food for its porcine residents - it was even rumored they had individual beds, and slept under sheets. That may have been hyperbole, but it underscores Baker’s belief that public health depended greatly on sanitary food production."

He didn't blame pigs for the filth and squalor in which they, um, wallowed.

Haiku spam and double digit sigma events

Haiku Schmaiku

Howdy Ma'am,
Just spam, I am.
Five syllables short

-- Bloggerel Doggerel blog, 2007

Verse is courtesy of The Climateer, who doesn't write about climate too often, thankfully! He has a great blog description which is perpetually relevant: "In war, everything not censored is a lie."

The Climateer DOES write about investment bankers who blame statistics for their poor trading decisions... or possibly, outright deceptive practices. There was a lot of that going on in 2008. I finally hoisted some posts about double-digit standard deviations from my bookmarks and read them.

25 Sigma Event Very Unlucky

From Climateer Investor and others along the way, it seems like a 25 sigma event is impossible. "How unlucky is 25 sigma?" (2011): When Goldman Sachs was Really, Really Unlucky
"One of the more memorable moments of last summer’s credit crunch came when the CFO of Goldman Sachs, David Viniar, announced in August that Goldman’s flagship GEO hedge fund had lost 27% of its value since the start of the year."

As Mr. Viniar explained, “We were seeing things that were 25-standard deviation moves, several days in a row.”

April was the month of mathematics

April 2020 was the scheduled date for the most recent Mathematics and Statistics Awareness Month. It is a biannual event, i.e. held once every two years. Sadly, it was uniquely ill-timed to coincide with the arrival of the full-force of the COVID-19 global pandemic. A lot of recurring events have fallen by the wayside.

Tea for 8 by S. Goldstine
Possibly even worse is the fact that I see no mention of
any activities for 2022. I noticed this while browsing through the pages of the online Mathematical Imagery SIG (special interest group) of the American Mathematical Society (AMS). I encourage readers to visit! Included here are two scaled-down examples that I liked. 

The Four-Color Theorem works for any map on a plane or a sphere, i.e. four colors are sufficient to color every neighboring region with a different color. For other shapes, say this toroidal tea set, eight colors were necessary.

The shape on the left is a group of super-imposed polar surfaces. There is much more, along with detailed explanations, equations, etc. 

 You will also find pleasing drawing such as those I shared in my Cornucopia of Mathematics post, dating back to the turn of the century, uh, this century. Although I didn't hot link to the images (well, maybe one), and gave full credit to the source, a 2003 academic event at a university in New England, I noticed a few months later that the source web pages had gone 404 error not found.


On the origins of Mathematics Awareness Month


As any blog reader of mine knows, I strive to find surprising information. The origin of AMS's Mathematics and Statistics Awareness Month can be traced back to none other than... Ronald Reagan?

Bard of the Deep State: Brookings not to merge with Heritage

The Bank for International Settlements (BIS) is the central bank of central banks. Think Tank Watch is similar to BIS, except it is for think tanks. Both are meta organizations although only BIS has global gravitas. Also, I suspect that Think Tank Watch lacks any governance role for think tanks, unlike the mild governance authority of BIS over central banks.

Think Tank Watch's editor-in-chief seems rather pleased with himself. There's nothing wrong with taking pride in good work.


Think Tank Watch saw something and said something


Brookings Institute to merge with the Heritage Foundation:
Think Tank Watch has learned that the center-left Brookings Institution is in the late stages of a merger deal with the conservative Heritage Foundation to form a new think tank behemoth called "Brookitage."

The news comes via unnamed sources. Is there any other way to get information in Washington D.C. than 'unnamed sources'? Of course not!

Making policy not shaping or influencing

"We cannot afford to be just a liberal think tank in today's polarized political atmosphere," said a senior level Brookings official. "Bringing the most well-known liberal think tank together with the most well-known conservative think tank would send a huge message to Capitol Hill. Things need to change."

It is unusual for think tanks to take such an active political role. Also, think tanks tend to be hothouses of similar ideologies. Brookings and Heritage are not similar, so merging will no doubt be uncomfortable for all involved. Also, Heritage is likely none too happy with that portmanteau of a name, Brookitage.

Why hasn't the growth rate of Real Potential GDP recovered?

Missionary Work Among Savages blog is authored by 2slugbait, a pseudonym for an econometrician. He recently wrote a post about whether President Reagan's 1981 tax cuts performed as advertised with the perspective of hindsight. I think his motivation was also to assess whether a similar supply-side approach could have been a better alternative to the fiscal stimulus measures implemented by President Obama during the 2008-2010 financial collapse.

Although the recovery during Obama's second term in office was one of the most anemic in U.S. history, 2slugbait's conclusion was that a supply-side effort would not have produced an enduring benefit.

Voodoo economics not so great


Economist Arthur Laffer was known for his Laffer curve. Laffer's recommendations about supply-side measures (rather than demand-side economic stimulus) were referred to as voodoo economics by detractors, most famously by former President George H.W. Bush. 
men standing around a cauldron
Voodoo economists in action?


2slugbait demonstrates empirically why supply-side economics was only mildly effective. Specifically, neither of the following worked out the way supply-side economists posited at the time:
  1. cutting the top marginal tax rate would encourage greater labor efforts and 
  2. more hours worked would have a greater net impact on increased personal savings than increased consumer spending would.
Graph with line series shaped like a bump
The (infamous?) Laffer curve


Skepticism about David Stockman and Laffer's tax policy recommendations during the Reagan Administration is the less interesting part to me. Tax cuts for middle-income wage earners (not solely those high net worth "job creators" 😕😡 ) CAN provide a modicum of economic stimulus, even though it is not enduring! That was apparent from 2017 to March 2019, as well as the early 1980s.

Something else is much more interesting to me: The long-term decline in Real Potential GDP. 2slugbait noticed this too in his post.

Real Potential Gross Domestic Product


According to 2slugbait,
"If the Reagan tax cuts actually affected the supply side of the macro economy... then we should have observed an unparalleled increase in the growth rate of real potential GDP... 
Yes, real potential GDP did grow at a pretty good clip immediately after the Reagan recession, but it quickly faded... even at its peak it was only barely above the growth rates during the Nixon, Ford, and Carter years and well below rates enjoyed during the LBJ and Clinton years."

Real potential GDP (let's refer to it for convenience in this post as RPGDP) is defined in the Federal Reserve Economic Data repository (FRED) as

Credibility and the Internet: Queuing Theory

This was old news about queues back in the 1990s, yet it was written up as an (Inderscience) journal article, and received coverage as though a new finding in the June 2010 issue of ScienceDaily, an online "new discoveries!" update service owned by Reuters. See footnote #1 for even more.

M/M/1 queues, Kendall notation, and models of balking and reneging behavior are certainly useful. However, the concepts and most models have been well-established for at least forty years.

This Wiley text book, Fundamentals of Queueing Theory, was published in 1998.



An earlier edition was published in 1983, and explains in detail the theory and application of the concepts presented in the journal article summarized by ScienceDaily in 2010.

A little more about M/G/1

Over at Math StackExchange, I noticed a rare inquiry. If you're curious to learn more about queues, go read my answer to this question, Kendall notation's “General distribution”, what does that mean?

I found this comment endearing:

Oh I thought that this stuff wasn't even used in real life jobs... I thought it was merely theoretical, but seems that I'm wrong!
I'm okay with the G general theory [G as the general case when you just don't know what sort of service time distribution to expect] since I'm not required to study it for now (I'm following an academic course), I just wanted to understand what the G meant and you helped me in that. Do you have any experience with multi-class queues too?

Chemical Heritage

This aluminum necklace was on display at the Chemical Heritage Foundation (CHF) in 2010. It was part of the CHF's Chemistry and Fashion: Making Modernity exhibit. A description of the necklace is still available via an unfortunately image-free post about Atomic Age women's jewelry

I like the necklace, a lot! Aluminum is very light; I do wonder whether the same necklace could be made of platinum or possibly iridium. If so, how it would it compare--in appearance (e.g. lustre) and weight-- to the aluminum version?

I wrote this post in October 2010. Times changed at the Chemical Heritage Museum since then, resulting in many broken links. This is an expanded version of that post, with replacement by valid alternative links for inline URLs. I apologize if I missed any. 

URL persistence hasn't been taken as seriously as the IETF and Internet Society had hoped; URL status, according to a Google Groups thread, as of 2013:

URLs are simply not persistent...from a recent study, about 15% of URLs from a large sample reach a lifetime of 1000 days. It's abysmal. And other studies back it up.

No Moore Chemical Heritage

Sadly, Chemical Heritage was absorbed by the Science History Institute in 2018, including the CHF's 5-story building. Most CHF collections can still be viewed at the museum's original location, at 315 Chestnut Street in Philadelphia, Pennsylvania. I was born in Philadelphia, and attended graduate school there, so I feel an affinity. 

The former CHF building is near Centennial Hall, the Liberty Bell, and adjacent to a nice residential neighborhood called Society Hill. Penn's Landing is a few blocks to the east. That's where William Penn first arrived on the shores of America. 

Gordon E. Moore helped found the Chemical Heritage Foundation, and his generous donations provided much of the initial and sustaining funds.

Interested in the legacy of Gordon Moore? A reproduction of his 1966 article, in which he introduced his famous law, is included in Understanding Moore's Law: Four Decades of Innovation. The book also recounts many observations by Moore, his peers, competitors, and others. It was written in order to commemorate the 40th anniversary of Moore's Law. 

Although "Understanding Moore's Law" was published by the now defunct CHF Press, the Science History Institute kindly keeps an electronic version of the full text available as a PDF for online readers.

Heritage of Chemistry: Moore notable, noble chemists

I promise that this heading will be my final pun for today. It is a double pun, the best kind!

When I first wrote this, chemist and materials scientist Andre Geim had recently won the Nobel Prize.  In merely 10 years, he went from the dubious distinction of receiving an IgNoble prize for levitating frogs with magnets to winning the Nobel Prize for producing a one atom-thick material consisting of carbon atoms, arranged in a hexagonal lattice.  Geim named it graphene, and mapped its properties: incredibly thin but still incredibly strong, good heat and electrical conductivity, almost entirely transparent yet very dense.

AOL Running Man Lives!

The running man created by AOL (American Online) was, and maybe still is, the most iconic representation of Internet dial-up connections for many users from the mid-1990s to 2010.

Apparently, he was still making appearances at tech events as recently as 2009, as seen here in Washington D.C.

Me


I am Ellie Heartsdale. I owned a small corner plot of land on an island sim in the west. I built a little house there, for me and the piggies. I went to the Second Life synagogue, in Nessus, on Friday nights.

My father was still alive then. I was working for the State of Arizona, Department of Health Services, Office for Children with Special Health Care Needs, as chief research statistician. That was my title, "Research Statistician, chief".

I was happy, but as usual, didn't realize it at the time.
