Into Every Life A Little Fertile Bird Poop Must Fall. . .

      A bird let loose a fine, fertile mixture of urine and feces from its cloaca onto my head on Christmas Day. Yes, a bird pooped on me.

       I expect my face looked similar to this house finch:

      The Italian (and other cultures') superstitions of a bird pooping on you being good luck is even mentioned in the Cornell Lab of Ornithology Web page:
"Flying Poop"

"Q: I have been asked to find out if Canada Geese, um, poop while they fly. I'm sure you have more important issues, but this is very important to the seven-year-old who goes to the driving range with me.

A: Birds are certainly capable of pooping while flying. They often poop just before taking off, perhaps to lighten their load. Although this might not reassure your seven-year-old, you might also mention that in some cultures people believe that is very good luck to be hit by bird poop."

       Having been through the experience of being "one in a million," I can tell you it sure doesn't feel so lucky, being a ways from home on a sunny Colorado day. . .as I passed fellow merry, well-wishing, chatty walkers with black-gray goo running from my hair down the side of my face. But, with a shower and some retrospective, I do realize how lucky I am. A friend reassured me with this photo of an egret (look at those ruffled neck feathers ;-)) and a nice landing:


     I am especially lucky because this is the second time I have been pooped on.The first was outside an Italian (maybe the birds knew?)  restaurant in downtown Denver. We stood outside the restaurant looking at the menu posted on the exterior wall when, sure enough, a pigeon let loose on my head and clothing. When I went into the restaurant to get cleaned up, the waiter laughed and said "Oh, yeah, they do it all the time with people standing there looking at the menu." Ha! Funniest Home Videos for Birds. I did think I heard the other pigeons cavorting afterward. It's good to know they have a sense of humor.

     I am also lucky and grateful for family, friends, fellow bloggers, and National Public Radio (and for the serial comma). The recent Science Friday rebroadcast on Temple Grandin, the autism spectrum, and her description of seeing life in pictures rather in words (as she proposes animals also do) struck me (post the recent avian experience):

      With the recent advent of increasing photographs and images on social media (Facebook, Instagram, SnapChat, and the like), we are all seeing life in more and more pictures. Though, being such a word lover, I truly hope we never go completely to a world of all images. What would I do with these thousand words I have stored up ready to go? All the puns waiting to be launched?

       Wishing you all a happy, safe, fertile year for 2014. The Christmas bird has deposited lots of seeds for blog topics for 2014 (the milky blue blood of horseshoe crabs, squid, and cuttlefish, "expanding" chickadee brains, as well as trilobite eyes and modern photography). Here's a preview of a majestic trilobite eye:

     Are there other topics that Partial Ellipsis of the Sun (PEOTS) might explore next year? I look forward to your ideas, suggestions, and seeds of thought. And, thanks for swooping on by.

Fertile Crescently,

In the Mobius Strip of Life, A Little Twist is Needed


     This is Math Month with 14 brilliant kindergarteners. We've gone from Fibonacci Numbers to Golden Spirals to Mobius Strips. The kids watched the following jaw-dropping, 3-minute video linking a Mobius Strip to the music of J. S. Bach:

     They watched the Jos Leys video transfixed. I heard more than one soft "Whoa!"

      The kids then drew on and cut their pre-made Mobius strips in half length-wise to learn more about the amazing looping properties of the Mobius strip. Then I created one more extra-long Mobius strip, expecting to cut one-third of the way into the strip creating one long loop intersecting with a shorter loop.

     I got two disconnected loops of green construction paper.

     Hysterical laughter ensued as Ms. Steph had forgotten to twist the loop. 

     It was GREAT!

     It looped perfectly into a discussion of scientists making mistakes and to the wonderful book I am reading (thanks, Jan!): Brilliant Blunders by Mario Livio (2013).




      In the preface, Livio starts by noting his standard answer to what his book was about: "It is about blunders, and it is not an autobiography." So far, it is a finely-woven quintuple helix of the biggest mistakes of Charles Darwin, Albert Einstein, Fred Hoyle, William Thomson (Lord Kelvin) and Fred Hoyle. Rosalind Franklin (see October 29, 2013 Partial Ellipsis of the Sun blog post here:  Rosalind Franklin: DNA Photograph 51) and her contribution to the discovery of the DNA double helix (not triple helix as Pauling hypothesized) are discussed in great detail. There are photos, letters, journal notes, and diagrams detailing the errors of these scientists. One reviewer wrote, "Even Einstein was no Einstein sometimes."  

      The word "blunder" according to Merriam Webster is from the  Middle English blundren, probably of Scandinavian origin; akin to Old Norse blunda to shut one's eyes, doze, Norwegian dialect blundra.Here's hoping that you will open your eyes to the beauty of these holiday Mobius strips:

and to this very creative person, Jos Baldwin, who blended (and surely blundered along the way) to this creation of 36 Mobius strips creating a Chambered Nautilus:




There are more photographs of this Mobius Nautilus here: Mobius Nautilus

      My world is looping back on itself as I remember the thrill of reading a first-year (ok, we called it freshman) English book that connected with my Geology 101 textbook. A chambered nautilus made of Mobius strips? W h o a . . .

     Wishing you all a good holiday (whichever you celebrate--or not) and winter filled with colossal mistakes, many children, and much laughter. . .and, perhaps, a Mobius tree:



 I look forward to our loopy conversation. (Sorry about the lack of an umlaut over the "o" in Mobius; I know you'll pronounce it Mer-bius not Moh-bius. . .)

Fracking in the New Millenium: Increase from 750 gallons to up to 8,000,000 gallons of Water to Frack a Current Well



        In continuing the discussion of hydraulic fracturing or fracking from last Tuesday,  the following words ring out the loudest to me (all the emphasis on numbers/words is mine):
       " A typical early fracture took 750 gallons of fluid (water, gelled crude oil, or gelled kerosene) and 400 lbm of sand. By contrast, modern methods can use up to 8 million gallons of water and 75,000 to 320,000 pounds of sand. Fracking fluids can take the form of foams, gels, or slickwater combinations and often include benzene, hydrochloric acid, friction reducers, guar gum, biocides, and diesel fuel. Likewise, the hydraulic horsepower (hhp) needed to pump fracking material has risen from an average of about 75 hhp in the early days to an average of more than 1,500 hhp today, with big jobs requiring more than 10,000 hhp."

       The full article, by Michael MacRae, of the American Society of Mechanical Engineers (ASME) explores some of the very early history of fracking (back to 1865 in PA) is linked here:


       The increase in those numbers, especially the amount of water used to frack a well is astounding: from 750 gallons to 8,000,000 gallons of water...Increasing the hydraulic horsepower from 75 to more than 10,000 hhp is a staggering increase in energy used just to pump the fracking mixture into the ground. And then, there is the issue of disposal of all that briny, chemical-filled fluid back into the earth via the over 144,000 disposal wells.

       Here in CO, an organization called Coloradans for Responsible Energy Development (CRED) is pushing the following message quite hard in tv/radio/print ads:

       "Through environmentally safe fracking, we’re tapping into Colorado’s vast shale reserves under our state. And we’re doing it responsibly. Coloradans everywhere are starting to learn that facts about fracking. That it’s safe and been a part of the American landscape since 1947. For example, in 2012 the Colorado oil and natural gas industry supported over 110,000 high-paying jobs and generated $1.6 billion in tax revenue for things that are important – like Colorado’s public schools, parks and roads."

        The italicized portion (mine) of the above quote is quite misleading. Fracking from the 1940's to the 1990's is so radically different from current fracking of shales (such as the Marcellus Shale pictured above) as to be truly considered a different process. The industry is considering fracking then and now to be the same. It is not. 

        Our governor may drink fracking fluid (only the "green" variety) but that is clearly such a small part of the fracking issue:

        Having worked on oil rigs in Texas I saw exactly the debris the oil and gas industry left above ground. Here is an aerial view of Denver City, Texas. All those white squares are oil rigs/pads:


       The debris the oil and gas industry is making below ground is not as visible. It is, however, using valuable resources (especially water) to extract fossil fuel and leaving behind chemicals.  Again, I don't have an answer. Of course, we need to transition from fossil fuel to renewable resources like wind and solar.

       On a positive note (My kids are always getting on me about being positive in any situation), I counseled a young woman today who is interested in the Picker Engineering Program at Smith College. The first graduates of the program started by Dr. Ruth Simmons are now almost ten years post graduation.  If anyone can figure it out, it'll be a Smithie. . .

        Thanks, I needed that!

        I welcome your input on fracking. Next week's post will be decidedly lighter! Have a good solstice Saturday, everyone, as the sun (sol) "stands still" (sistere).

Caramel Dioxide: New Fracking Ingredient?

Caramel Dioxide: New Fracking Ingredient?

      Leave it to kindergarteners to come up with great new things. After our CO2 experiment a couple of weeks ago on Science Friday, one of the teachers left me this note about his observations at the sensory table:


     "Caramel dioxide" as a fracking ingredient does not seem all that far afield...Besides the standard water and "frac sand," fracking mixtures have been known to include corn husks, gelatin/jello (The topic of fracking or hydraulic fracturing has been described by fellow bloggers as akin to nailing jello to a tree.):


guar bean gum, benzene, naphthalene, hydrochloric acid, sodium chloride (my kindergarteners know that one), ammonium persulfate, formic acid, and quaternary ammonium chloride. (Benzene, in particular, has been linked to causing cancer). In fact, you may look up the ingredients used in the fracking fluid of over 55,000 wells here:


     Well, well, well, I will back up to the definition of hydraulic fracturing or fracking first. If you haven't been under a rock for the past five years (pun intended again), you likely know that oil and gas companies use copious amounts of water, some sand as a proppant (to prop open pathways in the "permeability-challenged" rocks like shale)

and a mixture of chemicals used to thicken the water in order to suspend the sand in the water, eliminate bacteria in water that produces corrosive by products, and preventing corrosion of the pipe (among other things).

     The petroleum class I took in 1982 used A.I. Leverson's Petroleum Geology textbook from the 1960's. I recall still his description of petroleum geology as primarily the study of fluids. This is part of what concerns me greatly about fracking...the use of water in very large amounts to reap another fluid, especially one which is non-renewable.  Here in the arid west, where water is such a precious commodity. . .

      Petroleum Geology 101: Hydrocarbons are created in source rock (like shales), move to reservoir rock like sandstone and limestone) and are capped by impermeable cap or seal rocks:

     Note that fracking was originally used to open up permeability in sandstones and limestones (the reservoir rocks). The use of fracking to extract hydrocarbons directly from source rocks, such as shale, requires more water, sand, and chemicals under higher pressures. Fracking of shales since the 1990's is essentially hastening the movement of hydrocarbons out of source rocks without waiting for them to move to reservoir rocks (with their higher porosities and permeabilities).

       The overarching argument about fracking does distill to whether it is worth the resources and potential chemical contamination to extract hydrocarbons. In the short-term, perhaps it is, especially if it replaces coal extraction. Overall, investing in solar and wind power and other renewable resources sure makes a lot more sense in the longer term.

       This piece from the March 14, 2013 NY Times summarizes fracking issues well:

      The oil and gas industry's refrain is that fracking occurs thousands of feet below the surface and that ground water is only hundreds of feet below the surface. Yet, anything injected in the earth is certainly subject to moving along fractures to eventually reach the groundwater and surface of the earth. In addition, spilling of fracking fluid at the well  or storage sites is a very real concern. Having worked on oil rigs in the 1970's, I saw firsthand how careless some folks could be with those fluids around the well bore. And in our September Colorado floods, we saw how storage of anything used in oil wells could be compromised by mother nature.

       I certainly don't have all the fracking answers and I want to explore this topic further next week. I will leave you with this photograph of a 16-page flyer a friend received about guar gum used for fracking fluid:

          The flyer describes how guar bean gum is the same stuff used in your vanilla ice cream and in your fracking fluid. I believe I will go have some vanilla ice cream (with no guar bean gum) and ponder next week's blog. Better yet, add some caramel dioxide to my scoop. . .

         I would enjoy hearing your thoughts about fracking, caramel dioxide, guar bean gum. . .

"Styling" Stylolites. . .

"Styling" Stylolites

      It has been a long day in a big, downtown building with many stylolites:

     The official definition of a stylolite (The Free Dictionary) is: "A secondary structure found along contacting surfaces of adjacent calcareous rock layers, the contact zone appearing in cross section as a series of jagged interlocking up-and-down projections that resemble a suture or the tracing of a stylus."

     What they really are are reminders that limestone, under pressure, changes to marble and the dark bits of various insoluble minerals  like pyrite, clays, and iron oxides remain in the stylolites making them visible.  Stylolite is from two Greek words, stylos or pillar and lithos or stone. The stylolites are serrated or tooth-like surfaces at which darker minerals have been removed by pressure dissolution, in a process that decreases the total volume of rock. In other words, they are dark reminders of intense compression and stress:

     I believe it is no accident that they are found in Courtroom buildings around the world. They may look styling and cool, but they are reminders that dissolution under pressure leaves behind a dark, dark image. And, similar to the vegetable ash layer in the Humboldt Fog Cheese, (See November, 19, 2013 post)  it is that layer to which our eyes are drawn. 

     Yes, stylolites can be quite beautiful:

      I hope to remember that in decompressing this evening (pun very assuredly intended) from today's proceedings.

      Next week: I am considering writing about hydraulic fracturing or fracking. We shall see. Thoughts?

      Here's hoping your day did not include stylolites (unless you are researching or admiring them).

Not "Eureka!" but "That's Funny. . ."

Not "Eureka!" but "That's Funny. . ."


     "The most exciting phrase to hear in science, the one that heralds new discoveries, is not 'Eureka!' (I found it!) but "That's funny. . ."

        Isaac Asimov's words resonate for me partly because of the humor but also because of the ellipsis at the end of his quote. It is in that space of wondering, of trailing off, of inviting discourse that is so appealing. Growing up I learned to search for the "Aha!" moment. . . when, really, leaving the space to find new discoveries in the . . . is more inviting and collaborative.

         Asimov also wrote that: "It pays to be obvious, especially if you have a reputation for subtlety." I took those words to heart in making this segue to Clarke Knight, Smith College Class of 2014 and newest Rhodes Scholar:

         Ms. Knight (Clarke Knight of the Soul :-) ), a chemistry major, crew member, and book author is pictured above in the infamous Lyman Conservatory of banana plant glass pushing fame. Ms. Knight is from Henderson, Nevada, south of the Golden E Triangle of Ely-Elko-Eureka(!), Nevada:

          It is an area of the Basin and Range where I did follow-up field-checking after photogeologic-geomorphic mapping and space imagery analysis. Tromping around in the horsts and grabens of the extensional (or pull-apart) geologic features of central and northern Nevada was a true treat. Amazing fossils and fascinating geology surrounded us. Clarence Dutton wrote of the Great Basin in 1886:
Whoever has examined, even cursorily, the map of Western America must have noticed the following arrangement of the mountain masses: The great belt of cordilleras coming up through Mexico and crossing into United States territory is depicted as being composed of many short, abrupt ranges or ridges, looking upon the map like an army of caterpillars crawling northward.

     Another Asimov quote: "I write for the same reason I breathe--because if I didn't, I would die." I am not sure of Ms. Knight's thoughts on writing but I share Dr. Asimov's thoughts. His personal papers take up 464 boxes or 71 meters of shelf space. He wrote over 500 books and over 90,000 letters and postcards. His books are in 9/10 of the categories of the Dewey Decimal System (just call Isaac Iceberg Writer. . . )

      Dr. Asimov's first quote above has made me quite conscious of using the exclamation point versus the ellipsis. . .I welcome your comments from New Jersey to California and Germany to Yemen (Partial Ellipsis of the Sun Blog Reader Data: That's Funny. . .")

Cheese Imitates Geology: Thin Vegetable Ash Layer and Thin Iridium-rich Clay Layer

Cheese Imitates Geology: Thin Vegetable Ash Layer and Thin Iridium-Rich Clay Layer


      There is a small, wicker cheese basket at my local grocery store filled with little snippets of cheeses--the ends of various imported wheels and logs. This one caught my eye:


          I unwrapped it last night and found this written on the wrapper (just so you know I'm not making this up):

     A hairline layer of vegetable ash?! Oh my. 

     Of course, the iridium-rich clay layer found at the boundary of the Cretaceous period (about 65 million years ago) with the overlying Paleogene sediments first documented by Luis and Walter Alvarez (shown below) in Italy, sprang to mind. The limestone layers beneath the red clay are full of numerous species of foraminifera (forams) and the thick limestone beds above contain only one foram species. In between is this iridium-rich later of clay. In Italy. In Germany. In the Netherlands. In the U.S. All over the world.

      Iridium is a rare, silvery, white transition metal of the platinum family found in meteorites. It was named for the Greek goddess Iris after the rainbow colors in its salts and less than 3 tons a year are mined world-wide:

     Iridium is associated with the massive K-Pg extinction including the non-flying dinosaurs and a huge, diverse, plant population. (The boundary was called the K-T boundary for Cretaceous-Tertiary when the Alvarezes discovered it. The International Stratigraphic Nomenclature Committee has recently deprecated the Tertiary Period though; it now must be called Paleogene.) [First Pluto is no longer a planet; now we can't call it the K-T boundary any more. Sigh...]  And the likely location of the meteorite hitting the earth in the Gulf of Mexico is also well documented.

       What strikes me (no pun intended, okay, maybe...) about naming conventions in geology and in all areas, actually, is the creativity and force in coming up with these descriptive terms. As Clementine says to Joel when talking about her newest hair color in the film Eternal Sunshine Sunshine of the Spotless Mind, "Naming hair colors. Somebody has that job. I want that job!"

        Calling the thin layer of vegetables in the Humboldt Fog Cheese "Vegetable Ash" is truly inspired to this geologist and cheese eater.

         Last week: puddingstones that look like pudding. This week: Cheese that looks like limestone layers with a hairline layer of ash. It doesn't get much better than that full circle.

        Thanks for reading. I look forward to your comments, thoughts, and cheesy ideas.

Until then, "say cheese!" (And mean it).

Humboldtly yours,
Word Woman (aka Scientific "Vegetable Ash Layer" Steph)

Puddingstones: Plum Wonderful!

Puddingstones: Plum Wonderful Stones filled with "Berries & Currants" of Jasper & other Pebbles


     For some reason, all sorts of stones have been on my mind the past few weeks, including the wonderful Michigan puddingstones pictured above. Their name comes from the resemblance to English suet or pudding filled with berries and currants, and, well, they do look good enough to eat!

      Puddingstone, or  plum-pudding stone, is the name given to conglomerates (of different origins, compositions, and locations) that consists of distinctly rounded pebbles whose colors (in this case, Jasper chalcedony red) contrast greatly with the color of the finer-grained matrix (or cement) surrounding the pebbles. The Michigan puddingstones pictured above are likely associated with glacial activity of fairly recent origin.

     In contrast, I cut my geologic teeth in the Northampton and Boston, Massachusetts, area where we drove miles and miles from little scraps of outcrops to other little scraps of outcrops to look at the Roxsbury Conglomerate of the Boston Basin:

     Originally thought to be associated with shallow river and lake basins, the prevailing hypothesis is that these puddingstones or conglomerates are associated with very deep marine basins in a suite of rocks known as turbidites, associated with deep-sea submarine fans. They are also much, much older (and they look it!), dating from 570 to 595 million years ago.

      There are other puddingstones, such as the Hertfordshire Conglomerate in merry old England :

     And the Jelly Bean Conglomerate of Arizona and the western United States:

      I had the good fortune of attending geologic field camp in Arizona where we could see the Jelly Bean comglomerate stretching out for long distances (no driving needed, it was strictly a walk in the geologic park).

      Naming stones or rock formations based on their similarities to foods we eat is decidedly more fun than the geologic convention of naming formations based on the locale where they were first discovered. It is a sense of whimsy I shared with Robert W. Hickman, my first geologist boss, amazing teacher, and good friend. I am also writing Bob's eulogy today. Bob would have enjoyed this:


     Thanks for all you comments and suggestions. I look forward to a bit of puddingstone discussion with you. If you don't eat your meat, you can't have any pudding (Pink Floyd), but you may surely have some puddingstones.

Life Imitates Metaphor: Banana Plant Pushes Through Glass Ceiling at Smith College

Life imitates Metaphor: Banana Plant Pushes Through Glass Ceiling at Smith College

        A banana plant busted through one of the ceiling panes at the Lyman Conservatory at Smith College over the weekend. Smith College has witnessed many women pushing through glass ceilings over the past 100 plus years. Now, we have actual evidence that a pane of glass can be broken through, literally overnight, in this article featured in today's Hampshire Gazette, Northampton, Massachusetts.

     In this bizarre case of life imitating metaphor, Smith College has a most fitting symbol (living mascot?) of breaking through those clear barriers. A banana plant at Smith has many commonalities with Julia Child, Gloria Steinem, Otelia Cromwell (Otelia Cromwell Day at Smith is today!) and many other Smith College graduates. And, in so many cases, the women broke through the ceilings almost overnight...but it did take over 100 years of growth to get to the point where the pane could be shattered. The push came in the middle of the night with no witnesses. And yet, the push came. . .

     And, in an odd presaging, Marshall Schalk, professor emeritus of geology at Smith College, and I had a conversation standing near the very same banana plant in 1978 (it has been at the conservatory since at least 1904). He told me that banana plants were remarkably strong and forceful and that he would not be surprised if, one day, the plant pushed through the glass ceiling! "Just like a Smith!" he said (He called us Smiths, not Smithies).

     So, today, Marshall, life imitates metaphor. This photograph is for YOU!


       As always, I welcome your thoughts and comments on glass ceilings, Smith College or...,

Franklin, my dear, we DO give a damn!


                  "Franklin, my dear, we DO give a damn!"

     Rosalind Franklin's First Photograph of DNA structure



           Rosalind Franklin's extraordinary 1953 photograph of the DNA double helix was the impetus for Watson and Crick realizing the helix supports were on the outside of the structure with the phosphate "rungs" pointing inward. Until then, both Watson and Crick, Linus Pauling, and other researchers hypothesized the phosphates were on the outside. Franklin's research and extraordinary photograph 51 (shown below)

 were pivotal in understanding the double helix model. Yet, Rosalind Franklin received no credit for her pioneering work in x-ray crystallography of the DNA, or for the amazing photograph. Watson and Crick both later wrote that her photograph was "key" to their understanding of the structure of DNA. PBS has chronicled her story in a documentary entitled "Secret of Photograph 51:"


            And Brenda Maddox has also written Rosalind Franklin: The Dark Lady of DNA.

            My Halloween costume will be of Rosalind Franklin, complete with photo 51 emblazoned on a t-shirt, microscope, a DNA model, and a lab coat.

          I decided this was a wise choice after making DNA models with the kindergarteners on Friday. They asked me more than once "Was she a girl?" Yes, Rosalind Franklin was a girl/woman who, sadly, died at age 37 of complications from ovarian cancer. She did not receive credit for her amazing x-ray crystallography work on the DNA helix. Most (but not all) people I have shared her story with over the past week or so were completely unaware of her contributions.

           The kids and I also worked together on one giant table making a very long double helix. I (oh so subtly) mentioned that working on scientific discoveries and models together is the way to go.

          To you, Rosalind Franklin, thank you for your extraordinary x-ray crystallography, your methodical, detailed research, and for Photograph 51.  

           Frankly/Franklin, my dear, we DO give a damn!

 I would enjoy hearing your thoughts about Rosalind Franklin (1920-1958).

SHOW, not tell; Bird and Dinosaur chromosomes; and To(o) funny

         SHOW, not tell; Bird and Dinosaur chromosomes; and To(o) funny

    NPR's Science Friday discusses the art of displaying data in a user friendly and fascinating way in the article "Show, not Tell." The "infographic age" is here.


     Above, New York's carbon emissions are shown in real time. Clear, dramatic, understandable: data you can sweep right up ;-). 

     And 85 dog breeds are shown below based on four categories of herder, hunter, mastiff-like or wolf-like. Showing large amounts of data in a way that is quickly understandable has moved leaps and bounds from bar graph and pie chart days.

      On Fridays I leave the fascinating world of oil and gas and environmental geology for a few hours to work with 14 brilliant kindergarteners doing hands-on science. We made giant dinosaur nests and edible coconut bird nests and talked about clades. We made our own infographics last week showing bird and dinosaurs differing by a chromosome (simplified but effective as the kids ran around on the playground after looking at the chromosome bracelets saying "You're a bird!" or "You're a dinosaur!")

      If a had a really good infographic person I'd make these data into a fascinating SHOW:

 Organism                                   Number of Chromosomes

  Adder's Tongue (plant)                                   1260              
  Dogs                                                               78               
  Cats                                                                38               
  Birds                                                               78 - 80              
  Humans                                                           46               

    ...And tell you that none of the kids were at all concerned that the plant has so many chromosomes and that, (whew!) no one asked HOW the mom gives the X chromosome to her kid or the dad gives the X or Y to his kid.

       The kids in kindergarten don't do show and tell any more. They just DO.

       And finally, I believe I will need to sign off now. I am on a quest to find funny:

As always (4 whole weeks!), I enjoy hearing from you.

The Brain Continued, A Reassuring Lie, and a Keychain Carabiner

 The Brain Continued, A Reassuring Lie, and a Keychain Carabiner

    I started a new Quality Assurance project this week for a subcontractor doing work for the EPA. That's all I can say about that...But this cartoon about confirmation bias came to mind:


 It is from an article published on Fast Company's website. It's a long article but worth it:

      We tend to agree with what we already know, hang out with people who think like us, and support causes like us. We would rather hear a reassuring lie than an inconvenient truth.

       And sometimes, just sometimes, a new lighted LED keychain brings such a smile to my face about a reassuring (?), convenient absurdity:

 Enjoy. And be careful climbing out there!
