Tonight I went to a booksigning and a panel of SF authors at Reiter’s Scientific Bookstore in DC. Among the authors present were: Dr. Catherine Asaro, Greg Bear, Bud Sparhawk, Tom Purdom, Tom Ligon, Yoji Kondo (Eric Kotani), John Hemry (Jack Campbell), Charles E. Gannon, and Dr. Arlan Andrews. The roundtable discussion topic was “How Science Fiction Changes Everything” - How Science Fiction Serves the National Interest. The Washington Science Fiction Association also sponsored the event.

Some (all?) members of the panel are also members of SIGMA:

SIGMA is a group of science fiction writers who offer futurism consulting to the United States government and appropriate NGOs. We provide a new concept in public service “think tanks”– an association of speculative writers who have spent careers exploring the future. Many of us have earned Ph.D.s in high tech fields, and some presently hold Federal and defense industry positions. Each is an accomplished science fiction author who has postulated new technologies, new problems and new societies, explaining the possible science and speculating about the effects on the human race.

The event was mostly the panel fielding questions from the audience. I enjoyed the evening; it was quite interesting to hear the viewpoints of various SF authors, especially Bear and Asaro, as I’m a fan of both. At the signing Dr. Asaro mentioned that the cover of Alpha was her favorite. The artist was going to go with a flowing gown, but she told him, no, I’d rather look like this:

My wife’s family was in town for her grandmother’s and uncle’s birthdays (happy 92nd birthday, Margaret!; happy birthday, Paul!) so we all went to the Freer Gallery of Art in DC. Preston fell asleep in his stroller (but not before some very loud “OUTTA HERE!”s echoed off the gallery walls). The rest of us enjoyed it. :)

I spent most of the time in the galleries of ancient Asian ceramics, and bronze. I’ll definitely be going back for a more leisurely visit, but not around Preston’s naptime.

Some highlights below (click any image for a slideshow), but a lot more via the photography page.

Tim Berners-Lee in 2001

It was twenty years ago today (March 13, 1989) that Tim Berners-Lee wrote up his proposal for management at CERN, titled “Information Management: A Proposal“.

This document was an attempt to persuade CERN management that a global hypertext system was in CERN’s interests. Note that the only name I had for it at this time was “Mesh” — I decided on “World Wide Web” when writing the code in 1990.

Berners-Lee’s boss thought his proposal was “vague but exciting”. :)

Preston, Dylan and I went to the Smithsonian National Museum of Natural History yesterday. Preston just loved the Insect Zoo. No way was Dylan going to hold a bug, but it was hard to keep Preston away. He also held a big beetle, but I couldn’t get a picture as I had to help keep Preston from squishing it.

The new Ocean Hall is quite good. Even Dylan was impressed by the giant jellyfish (seen in foreground). Full-size right whale hangs from the ceiling, and videos of ocean scenes line the walls. Lots of informative exhibits about the ocean.

A lot more pictures are viewable via the Photography page (Natural History link)

 

A 3-D image of Cleopatra has been rendered by computer imaging based on images from ancient artifacts.

Egyptologist Sally Ann Ashton of Cambridge University says the image(s) reflect the Queen’s Greek heritage. Cleopatra was born in 69BC into an Egyptian - Greek dynasty. She took the throne at 17 and by 20 had seduced Julius Ceasar…

Researchers at PennState have published the DNA sequence of an extinct Woolly Mammoth; see the news article at Nature.com, or the November 20, 2008 issue of Nature for a paper by Miller, et al. (Nature 456, 387-390: “Sequencing the nuclear genome of the extinct woolly mammoth“).

Mammoths went extinct some 10,000 years ago, but have been found preserved in Russian permafrost. The hair from one of these preserved (mummified) ancient beasts was used to retrieve DNA. Hair is useful for such extractions as it is relatively easy to wash away contaminating (foreign) DNA.

One tidbit that I found quite interesting: where did the researchers get the Mammoth hair? They bought the hair on Ebay.com! You can too, for only $175.00 for 2.5 grams. Yes, the researchers did verify that this was actual mammoth hair. Anyway, the big question is whether or not we will shortly have a Mammoth clone. Short answer: not any time soon. This is just the first step, but is a major one.

Our ancestors did see live woolly mammoths; here’s a cave painting in France depicting one:

A new exhibit at the National Gallery of Art opened yesterday: Pompeii and the Roman Villa. Preston and I went to see it. For an active two-year old, Preston was surprisingly well-behaved. He was most impressed by the large bronze sculptures of horses’ heads (whazzzaaaat???!!) and the dogs attacking a wild boar (whazzzaaaat???!!).

At one stop Preston did point and say “MOM!!!”. However I couldn’t tell if he was pointing to a statue of Aphrodite or the blonde standing next to it. So I covered both bases with “Yes, that looks like mom, but she’s not here right now”. (The picture at left is not Aphrodite; it’s the daughter of Marcus Nonius Balbus. You’ll have to go to the exhibit to see Aphrodite). :)

The exhibit is in the East building, and is on two floors. The exhibit is free, though I recommend the $5.00 audio tour. I found the sculptures particularly captivating. I hadn’t realized before that the blank eyes on a lot of ancient statues actually originally had inlays. Most of the time such inlays have not survived to the present, but in a number of the exhibit sculptures they do. This made the art even more striking and realistic. The frescoes were amazing; such color and detail. One piece (rather small, maybe 1.5ft on a side) appeared to be drawn in red pencil on marble. The detail on that piece was absolutely amazing. They definitely had some very talented artists 2000 years ago.

The opulence of Pompeii does show through in the sculptures and frescoes. The exhibit also contains paintings and sculptures from the 19th century (and later?) that show an artists’ recreation of Pompeii before the disaster. Wow. I think it was Augustus (Octavius) who was so captivated by the area around Naples that he bought an island.

The Archimedes Codex is the story of the Archimedes Palimpsest, formed when a medieval prayer book was created by taking parchment (sheepskin pages) from several ancient codexes, scraping off the old text and re-using the parchment. One of these ancient manuscripts happened to be the earliest surviving copy of Archimedes Codex C. An informative website is dedicated to the Archimedes Palimpsest.

The old prayer book/palimpsest was purchased in 1998 at auction for $2million. The new owner entrusted Noel, the curator of the Walters Museum in Baltimore, to unlock its secrets. Netz is a Stanford classicist; the two authors alternate chapters.

I was more interested in the technology used to uncover the Archimedes text than in the text itself however a majority of the book is on the text and how it contributes to our understanding of Greek mathematics (geometry, combinatorics, etc.). Only the last 20 pages focus on what caught my attention initially, namely the use of a beamline at the Stanford Linear Accelerator Center (SLAC) to do X-ray absorption studies on the palimpsest. These studies reveal hidden text via the iron in the original Archimedes text’s ink. I’ve done X-ray absorption (EXAFS) studies myself at SLAC so I liked the tie-in.

I think Noel is either being tongue-in-cheek or is a new earth Creationist (ick!). He once says that sheepskin evolved “or was Intelligently designed” with more antibiotic properties on the side facing out. In another passage , when discussing dates in the codex, says the dates as written by the orthodox monk were from the origin of the earth - “which as everyone knows was 5500 BC”. He can’t possibly believe that the earth was created ~7000 years ago! Anyway, the Archimedes text was written ~6-900 AD, while the Prayer Book it was made into was written ~ 1200 AD.

Interestingly (and sadly), as described in the book, most of the damage and deterioration of the book took place not in the past, but in the 20th century! The book today was very brittle, moldy, and glued(!) together.

The boys and I went to see Kim MacQuarrie give a talk Thursday night about his new book, “The Last Days of the Incas” at Olsson’s Bookstore in Arlington, VA. MacQuarrie is a documentary filmmaker, and he spent some 4+ years in Peru. While there he spent some time living among a “newly discovered” Amazonian Indian tribe. His interest in the Inca was piqued, and he subsequently spent 3 years researching and writing this book. He goes over the story of how ~160 Spanish were able to “conquer” some 30,000 Incas (and eventually the entire Inca civilization of some 10 million). The Spanish killed the Inca ruler Atahualpa in a despicable double-cross (the Inca had filled a room with gold as a ransom; the Spanish took the gold and killed Atahualpa anyway). That story is well known. Turns out the Inca didn’t just lay down their arms quietly after that. The book goes on to tell about the ~40 year “guerrilla” war the Inca waged against the Spanish after the execution of the Inca ruler. He touched on the “discovery” in 1911 of Machu Picchu by Hiram Bingham, and also for the modern search for the lost Inca city of Vilcabamba ( the search is still underway).

Enjoyable talk, and the author inscribed a copy of the book to me afterwards. I believe he currently lives in the DC area. Interestingly, I saw him on the subway on the way home later in the evening (he was in another car); I wonder if he saw me reading his book. :)

The audio recording of the talk is available (from my Canon Powershot S3 IS).

I spent a relaxing afternoon yesterday at the Sackler Museum’s “In the Beginning: Bibles before the Year 1000″ exhibit. As I was walking through the gates behind the Smithsonian Castle, I noticed the sign on the fence: WiFi @ SI. Nice! Turns out there are a few free wireless hotspots on the Mall now, this area (Haupt Garden behind the Smithsonian Castle) being one of them.

The exhibit at the Sackler was very interesting- they even have some fragments of the Dead Sea Scrolls (from ~60AD) on display. My favorites were the illuminated manuscripts from the 10th century - especially the purple-stained vellum with real gold/silver lettering. The exhibit goes through Jan 7, so stop by if you get a chance - it’s free.
