Gaiman, A Fun Guy, on Beatrix Potter, Science, and Art: You Can't Have One Without the . . . Others

         The scientific illustration of mushrooms and other fungi by Beatrix Potter, children's book writer and mycologist, is part of the inspiration for a poem by Neil Gaiman, "The Mushroom Hunters."



        The blending of science and art is described in Gaiman's poem, which begins:




      "Science, as you know, my little one,
is the study
of the nature and behaviour of the universe.



      It’s based on observation, 
on experiment, 
and measurement,
and the formulation of laws to describe the facts revealed."





     "The Mushroom Hunters" is read by Amanda Palmer in its entirety here.

      Mushrooms, which are closer to animals than plants in their origins, are both mysterious and mundane. The poem continues (after a break):


      "Before the flint club, or flint butcher’s tools,
The first tool of all was a sling for the baby
to keep our hands free
and something to put the berries and the mushrooms in,
the roots and the good leaves, the seeds and the crawlers.




      Then a flint pestle to smash, to crush, to grind or break.

      Some mushrooms will kill you,
while some will show you gods
and some will feed the hunger in our bellies.

Identify.




      Others will kill us if we eat them raw,
and kill us again if we cook them once,
but if we boil them up in spring water, and pour the water away,
and then boil them once more, and pour the water away,
only then can we eat them safely. 




Observe.

Observe childbirth, 
measure the swell of bellies and the shape of breasts,
and through experience discover how to bring babies safely into the world.

Observe everything.





And the mushroom hunters walk the ways they walk
and watch the world, and see what they observe.

And some of them would thrive and lick their lips,
While others clutched their stomachs and expired.
So laws are made and handed down on what is safe.




Formulate.

The tools we make to build our lives:
our clothes, our food, our path home…
all these things we base on observation,
on experiment, on measurement, on truth.




And science, you remember, is the study
of the nature and behaviour of the universe,
based on observation, experiment, and measurement,
and the formulation of laws to describe these facts.




The race continues. An early scientist
drew beasts upon the walls of caves
to show her children, now all fat on mushrooms
and on berries, what would be safe to hunt.





      The men go running on after beasts.

      The scientists walk more slowly, over to the brow of the hill and down to the water’s edge and past the place where the red clay runs.




     They are carrying their babies in the slings they made,
freeing their hands to pick the mushrooms."



   

Have you hunted for mushrooms? My friend described finding some 'shrooms that helped him see the earth breathing. . .

You've Got to Know When to Fold 'Em: Origami, Science, and Engineering

     Origami, the ancient art of Japanese paper folding, is used extensively in creating scientific and engineering products that rely on careful packing and unpacking.


      Origami is not just for a thousand paper cranes any longer. . .




        Space Station and satellite shields and solar arrays must be carefully packed for the trip to space then unpacked once in orbit.




     These giant panels start out in paper and computer models.


  
      Robert Lang is a leader in the field of origami applications. This excellent 5-minute video shows Lang and others from Brigham Young University, UT, and the myriad origami-inspired creations.




     In addition, origami inspired microscopic folds in medical products, on the order of nanometers.



           The movement in these origami unpackings is often quite graceful.



     One Christmas, ZoĆ« made me a thousand origami cranes. That was a wonderful, graceful unpacking!



     Do you use origami, either for fun and/or scientific/engineering purposes? 






Time to fold,
Steph

Today, the Brown "Tourmalion" Marble in the elevator made me smile. I like both tourmaline and tourmalion, roar. . . ;-)

Bridgmanite and Smithsonite: One Shocks, the Other Doesn't



          Bridgmanite is the most abundant mineral on earth, comprising 38 percent of earth's volume, primarily in the lower mantle at depths below 400 miles (670 km), but was just recently given a name this year.


         
          
          Bridgmanite is a magnesium iron silicate (Mg,Fe)SiO3 which shows the effect of being shocked by impact as part of a meteorite hitting the earth, as seen in this hand specimen from Australia:


  

          and more pronounced in thin section:


  

        It was named for Percy Bridgman, a Nobel Prize-winning physicist. Before being identified in a meteorite, the mineral was loosely referred to as a silicate perovskite:


          By geologic naming convention, a mineral cannot be named until actually examined in hand specimen (hard to do 400 miles deep). So, American researchers looked at a meteorite sample that had fallen in Australia in 1879 as a likely candidate for sampling material similar to this deep mantle mineral. They used a test that involved the use of a micro-focused X-ray beam in conjunction with electron microscopy. And, thus, a mineral was named in the:


      In contrast to the shocked appearance of bridgmanite, the strikingly smooth, pearly luster of smithsonite, a zinc carbonate, shows the effect of slow, undisturbed crystal growth:


           The crystals often form in grape-like clusters referred to as botryoidal:


          Zinc carbonate or zinc spar (ZnCO3) or smithsonite, was named after James Smithson, the same chemist and geologist who donated money for the Smithsonian Institution. Smithsonite has a hardness of 4.5 and a specific gravity of 4.4 - 4.5. In addition to the green, and blue-green colors, it also occurs in lustrous, pearly pink crystals:


       Though you may have guessed my favorite, the blue botryoidal, smithsonite clusters:


     How about you? Were you shocked to learn bridgmanite was only recently named? That smithsonite occurs in so many pearly, lustrous, botryoidal forms and in so many colors?

Looking forward to your often shocked and shocking comments (as well as your pearly luster),

Tortoises, Putnisite, John Cleese, and Better Creativity Tools, According to SCIENCE!


     This week I'd like to start with an article about creativity and writing which is, according to the Fast Company title, backed up by science! It includes tortoises and John Cleese video (With this Monty Python crowd, I imagine "according to Cleese!" may have the same effect as according to Science!)



Here's the link to the full article based on SCIENCE:

          Creativity according to SCIENCE

     Science was the top word Googled, ahem, researched, on the Merriam Webster website last year:

             Top word of 2013 is science

       I imagine editors are happy to see science thrown into a title whenever possible. A quick scan of the Fast Company homepage shows 4 articles containing "according to Science" on the main page. Do not get me wrong, I am happy to see science getting so much press. Although, at times, it seems thrown in a bit gratuitously.(Gratuitous throwing is a real thing in Ultimate Frisbee, a favorite sport for my son, his friends, and dogs):


[The frisbee player and dog in the photo are not related to me though;-)]

      Back to the article...The usual things that help creativity like exercise, sleep, moving on to something else and coming back after a percolation period are well-known, even not according to science. Writing with pen and paper has always been a creative juicer for me...There is something about the physical act of making the letters that a keyboard does not do. And now, I know, according to science, it works. . .

      Mr. Cleese notes that creativity is like a tortoise in that it pokes its head out gingerly to see if it is safe to stay out.




      He speaks of writing a funny sketch, losing the paper it was written on, and then recreating it from memory. When Mr. Cleese found the old sketch, he realized the newer one was much funnier.




      I am going to set this post aside for awhile and see how that percolating works.

      Percolating results:

     Popular Science is an oxymoron these days.

     Gilda Radnor's quote about creativity percolated through: "I can always be distracted by love, but eventually I get horny for my creativity."




      Hope you are having a wonderful Earth Day enjoying science and creativity.

Scientifically!,

Fossilized Swedish Ferns: Don't Step on My Toe, Sis!


       The beauty of this 180 million-year-old fossilized fern from southern Sweden shows cells in various stages of mitosis. It combines both rocks and plant organelles frozen in a volcanic flow.





      The study was published last week in by Benjamin Bomfleur, Vivi Vajda, et al:


             FOSSIL FERN CHROMOSOMES


      The fossil had been languishing in a Swedish Museum drawer since the 1960's. The amazing thing about the specimen is the degree of cell detail shown with nuclei intact, distinct cytoplasm, and cells dividing, preserved as a hot brine of minerals replaced the cell structures. What a mitosis show!



     The fossilized fern in the family Osmundaceae is essentially identical to the modern day Royal Fern, with little change in genome or DNA content. Like the classic horsetail fern, this Royal Fern is the same today as during the Jurassic Era. It is quite comparable to the cinnamon fern of the eastern U.S. and Canada.

     This living fossil cinnamon fern reminds me, on a different scale, of mudcracks and other features seen on aerial images and segues to this amazing view of Moab, Utah, just published this week by the U. S. Geological Survey:

     
    The wind deposited and eroded features includes numerous fins and arches show in the southwest and northeast portions of the image around the central city of Moab. These features on the ground in the Jurassic Entrada Sandstone look amazing and represent such change:





   So, on one hand, here's a Jurassic fossil fern that hasn't changed in 180 million years, and a Jurassic-deposited landscape that is being eroded and changed every day. Recent collapses of arches in nearby Arches National Park allude to this change.

    Isn't geology grand in all the contrasts and similarities? Have you been to these places? Were you in awe, wonder, happy and rich in fossils?


A fossil and Utah fan,
