Nuremburg Chronicles Empedocles

Anaxagoras and Empedocles, from the Nuremburg Chronicles

In my last post, I showed the statistics of what this blog has accomplished so far. I feel very good about where we’ve been, but now it’s time to describe where I plan on going this coming year.

Given that I am not teaching chemistry this school year, my work on the Elements Unearthed project has slowed down a bit as my attention has been diverted elsewhere by the astrobiology projects (the podcasts and CLOE animations) and other projects that I’ll describe next week. I anticipate teaching chemistry again next year, and I am in the process of writing up a series of grant proposals (all of which have to be done by Feb. 1) that, if successful, will provide funds for purchasing some iPad tablets and probeware that will allow us to do some environmental field research.

In the meantime, I have a large backlog of videos that I have taped of various mine tours and interviews I’ve done across the country. I need to edit these into final videos and report on them in detail on this site. In order to keep myself on track, I’ve created a schedule for when I’d like to do each video and the topics I’ll cover here as I work on them.

This January, 2012, I am going to start at the beginning and look at ancient chemistry and our knowledge of the elements in prehistoric and early historic times. Then in February, I will start to work on my Greek Matter Theories videos. I have previously created all the script and narration and have even set up the video files and begun the graphics and animations. It’s high time I finished these. I’ll start with an overview of the Greek Ideal in philosophy and science, then talk about Thales and the Miletian School, then Parmenides and Zeno and the Eleatics. In March, I will talk about Heraclitus and Empedocles and the atomic theory and Plato. In April, I’ll move on to Aristotle, Epicurus, and the debate on elements versus atoms, ending in the theology of St. Thomas Aquinus and how atomic theory came down through the Middle Ages.

In May and June I’ll discuss the practical side of chemistry, with a look at ancient crafts, including metalworking, glass making, and other medieval technologies, including a detailed look at Agricola’s De Re Metallica (which I have many photos of).

By July I should have the funding I need in place to start the field research. My plan is to partner with another school, perhaps Tintic High School or Wendover High School, to travel out to nearby mining sites and use the probeware and iPads to collect and record data on soil and water environmental conditions, such as the pH of soil and runoff water near old mine dumps. I’m especially interested in seeing if the EPA efforts to mitigate contaminated soil in and around Eureka, Utah have been successful. I’ve talked about those efforts in previous posts (especially here: 
http://elementsunearthed.com/2010/06/09/the-legacy-of-the-tintic-mining-district/
 ), so I won’t talk about them again now. We would use GPS coordinates and GoogleEarth to set up a grid of sample sites both in and out of the recovered area. We would sample the surface and two feet below ground. It would require several trips and coordination with local students to gather the data, but it is a project that would fit very nicely with the research I’ve already done. If I can get enough money together, I would like to rent a portable X-Ray Fluorescence Spectrometer which can read element abundances nondestructively on the site.

In preparation for all this, I need to make one more trip to the Tintic district in June to photograph and videotape the mines in the southwest area, which were the first mines discovered, including the Sunbeam and Diamond mines. One of my great grandfathers, Sidney Tanner Fullmer, died as a result of injuries suffered in an accident while working in the Diamond mine, leaving my grandmother an orphan to be raised by her aunt and uncle. So this history has a particular interest to me.

One thing I plan on doing, if we can work out a partnership, is to set up an evening in Eureka at Tintic High School where townspeople can come in with photographs and tell their stories of mining and life in Eureka before and after the EPA efforts. We’ll scan the photos and videotape the recollections, then combine all that with the video I’ve already done of the Tintic Mining Museum and local area. Ultimately, my students will help me script and edit a three-part video on the Tintic District, perhaps even done well enough that we could market it to KUED, the PBS station in Salt Lake City.

The months July, August, and September will be dedicated to this effort and will result in the best documentation created so far on video of the history and present of the Tintic Mining District.

October will be dedicated to Zosimos of Panopolis and such Arabic alchemists as Jabir ibn Hayyan. November will begin a discussion of European alchemists, from Roger Bacon and Ramon Llull through the Middle Ages. I’ll draw on the many photos I’ve taken on alchemical texts at the Chemical Heritage Foundation. The history of alchemy will continue through December, 2012 and on into January, 2013. In February and March, 2013, we’ll discuss the emergence of modern chemistry through Boyle, Priestley, and Lavoisier through Dalton, Avogadro, Berzelius, and others.

In April through June of 2013 we will switch gears and talk about nucleogenesis and the origin of the elements, then the physicists and chemists that have helped us understand the structure of the atom and quantum mechanics. From there, I will probably begin to talk about individual elements and how they are mined and refined, with examples of the mining districts where they come from, such as the history of the Viburnum Trend in Missouri and the lead mines there, or the gold mines of Cripple Creek, Colorado. I really do have enough materials now to keep this blog going for at least two years. And I’ll be gathering more all the time. I will also dedicate occasional posts to my efforts as a chemistry teacher and to science education in general, including my experiences at conferences, etc.

Well, it is an ambitious schedule. I hope to do at least one post per week, probably on weekends. I hope to complete at least one video segment every two months or so. Next week, I’ll start us off with an overview of the history of chemistry.

Once each year I like to go over the statistics for this blog in detail to see what posts have been the most popular, which search terms are finding this blog, which videos are most watched, etc. I’m not doing this just for an ego trip, but to be able to report the impact this site is having. I have had some very generous sponsors over the three years this blog has been running, especially the American Section of the Société de Chimie Industrielle (which paid for my fellowship in 2009) and the Chemical Heritage Foundation, which provided such a wealth of resources in its collections on the history of chemistry. It was during the time of my fellowship that this blog really began to find an audience, and it has been growing ever since.

Stats for the Elements Unearthed

Monthly Stats for the Elements Unearthed Blog

So here is where this blog stands: As of today, there have been a total of 67,620 visits to this site. As seen by the histogram, the number of visits has shown a definite annual pattern consistent with the school year – visits are lower in the summer when school is not in session, rise in August and September, stay high in October and November, dip a bit in December due to Winter Vacation, then rise again in January and February and peak in March, then gradually decrease as the school year winds down in April and May. This same pattern has repeated for the last three school years, but has grown each year. Last year, in the 2010-2011 school year, my best months were slightly above 3000 visits. Now they are topping out above 4000 and I hope they will hit 5000 by March.

Granted, compared to some popular blogs with thousands of hits per day, 5000 per month doesn’t sound like much. However, I am pleased – this is a rather esoteric blog dedicated to the history of chemistry and chemistry education. The yearly pattern shows that I am reaching my intended audience of high school students and teachers. This is also shown by the types of searches that reach my blog.

Although there are always some unrelated search terms that somehow reach my blog (the biggest ones are “Ocean City, New Jersey” and “Punxsatawney Phil” because I visited both places in 2009 and showed some pictures), by far the majority of search terms are related to chemistry and its history or to science education in general. I’ve gone through the search terms and compiled them into categories, mostly so that I can make plans for the future. Here are the top searches that reach this blog: (1) Greek Matter Theories (3473 searches) with Aristotle, Democritus, and Thales being the biggest ones; (2) the Periodic Table of elements (2288); (3) beryllium (1600); (4) Alexandre Beguyer de Chancourtois (1397) – this is a bit surprising, but apparently my animation of his telluric screw periodic system and description of his work is one of the few sites out there about him; (5) the Tintic Mining District (1041); (6) the history of the periodic table (868); (7) science education (862), especially using iPads in science classes; (8) early modern chemistry (822), including Lavoisier, Boyle, Priestley, Dalton, and Newton; (9) alchemy (732), with love potions, Khunrath, Basil Valentine, Zosimos, and Maier the highest; (10) water and wind turbines (618); (11) strange attractors (586) – this is another odd one, since I only mentioned it once, but it was in my most popular post; (12) mercury (554); (13) early technology (514), such as Roman glass, Pliny the Elder, Agricola, Neri, and others; (14) mining in general (455) – such terms as overburden, open pit mine, ball mill, and headframe; and (15) Cripple Creek, Colorado (315).

The videos that I have created for this project are posted on this blog (under the video tab) and on YouTube. The History of the Periodic Table, featuring Dr. Eric Scerri of UCLA, is my biggest hit so far. All parts of this video have been watched a total of 11,474 times as of 1/7/2012. There are even a few derivative works on YouTube that take parts of my video – a section on Henry Moseley, for example – and combine it with parts of other videos with Bill Nye, etc. I’ve had quite a few comments on how useful this video has been for chemistry teachers out there, and I am very pleased with the results so far. There is also a version with Portuguese subtitles done by a professor in Brazil; I’m not sure how many times that has been seen. My separate video that showed only some animations of the periodic table has been watched 416 times.

The second most popular videos have been the two parts on beryllium – its properties and uses, and how it is mined and refined. It has been watched a total of 3219 times, with the separate video on the geology of beryllium watched itself an additional 153 times. The Discovery of Synthetic Diamonds has been watched 745 times and the demonstration of Glass Blowing 754 times. These have been the most popular videos related to this project.

In conclusion, the most important question is: Have I succeeded in my attempt to bring the history of chemistry and chemistry education to the general public, and specifically to teachers and students? All indications, based on these statistics, are that I am succeeding and that that success is continuing to grow.

The last several posts have been about astronomy and space science education, and although some search terms have reached these posts, not many have. For various reasons, not the least of which is that I want to keep this blog focused on my original intent, I am starting a new blog which should be up and running by Wednesday night on space science education and resources for teachers to use now that we are in the golden age of astronomy. I will be doing quite a bit of education outreach on these topics over the next few years, if all goes well, and they deserve to have their own blog. I will include links here once that is ready to visit. I will post to this new blog once per week on Wednesdays.

The statistics also point out which topics have been most popular, and give me direction on what to post about in the future. In my next post, I will give you a schedule of what I intend to discuss over the next year and a half and when I will have the related videos completed. I will try to post once per week, probably on weekends. I have much more material from my fellowship at the Chemical Heritage Foundation that I haven’t shown or discussed here yet, and I look forward to digging into it all. I have also visited many sites related to mining and refining of the elements which I have only mentioned in passing. It’s time to edit all that footage and photos into videos for this site and YouTube. I expect the next few years to be busy, productive, and rewarding and to reach even more people than I already have.

Ramon Llull portrait

Portrait of Ramon Llull

As we have studied the history of chemistry for our recent unit in Honors Chemistry, I’ve had my students do a bit of research on what is known and supposed about various alchemists. For example, a student in each of my sections was assigned to research Ramon Llull, the Majorcan alchemist. We started by finding out what is known about the real person. He was born in Palma in 1232 AD, and was a courtier, poet, and womanizer at the court of King James of Aragon, then had a religious epiphany that converted him into a fervent missionary for Catholicism. After a nine-year hermitage and writing many religious tracts, he set off on a series of missionary journeys to North Africa. He was fluent in Arabic and was unusual for his time in that he believed in converting the Muslims through reasoned argument instead of Crusades and the sword. He wrote some of the first works in Catalan, his native language, and died after being stoned in Tunis.

I also had the students research what is attributed or credited to the person in tradition and later writings, such as Ramon Llull’s alchemical works and his having created the Philosopher’s Stone.

Each student also had to find an image of the person and include it, then take their short report and convert it to simple bullet points to summarize their findings. I’ve now taken those bullet points and turned them into a Keynote/Powerpoint slide show and added their images as well as photos I took last year at the Chemical Heritage Foundation as part of my fellowship sponsored by the Société de Chimie Industrielle (American Section). This is the first time, except for a few progress report blog posts, where I have started to use all the materials I assembled. I am attaching it here, and hope you enjoy going through it and using it in your own classes.

Sorcerers Apprentice

A Sorcerer’s Apprentice Masters the Transmutation of Copper into Gold

It was my privilege last summer to dig into the very books these alchemists wrote, and I’m still digesting what I discovered. One result has been my own creation of the White and Red Elixirs and the formation of the Stone itself; in fact, I demonstrated my alchemical prowess for my students by converting copper into silver and then into gold. Several of my students had achieved the inner transmutation sufficiently to successfully direct the Stone’s powers as well, as shown in the photo. (Of course, we really aren’t making gold. This is the old “Alchemists Dream” activity where copper pennies are coated with sodium zincate [using a combination of 6.0 M sodium hydroxide and zinc powder], then heated gently in a Bunsen burner flame to alloy the zinc with the copper to form brass, which looks like gold).

These student-created projects are part of my overall philosophy of science education and the main rational of this Elements Unearthed project: that students learn best when they are actively involved in sharing their knowledge with others. With modern tools for publishing on the Internet through blogs and PDF files, Powerpoints and videos, students now have an audience for their work that is much greater than simply their peers and teachers in class. Tomorrow is the unit test; we’ll see if my theory holds water then!

Finally, after months of waiting and effort, the two videos on the history of the periodic table are complete. Here they are:

The title of this video is:   The Periodic Table Part 1: Before Mendeleev

It’s YouTube links are:

(Part 1-A)
and  

(Part 1-B)


The title of this video is: The Periodic Table Part 2: Mendeleev and Beyond

The YouTube links are:

(Part 2-A) and:

(Part 2-B)

They feature interviews with Dr. Eric Scerri of UCLA, to which I have added my own narration, animations, illustrations, photos, captions, etc. as well as publication artwork and notes by Edward G. Mazurs (see my previous Periodic Tables posts). I have edited the videos into two parts. Part 1 covers the events leading up to Mendeleev’s invention of the periodic table including the work of several precursors such as de Chancourtois, Newlands, Odling, Hinrichs, and Meyer. The second part covers Mendeleev’s working out of his periodic system and the work of his successors, as well as some interesting questions such as whether the periodic table can be entirely deduced from quantum mechanics and the mystery of the Knight’s Move pattern of properties. Part 1 is 17 minutes long and Part 2 is just under 20 minutes. I am very pleased with the results; I’ve been using every spare minute to complete the editing which is why I haven’t posted here for so long. I hope you feel it is worth the wait. Please let me know what you think!

In addition to placing them into this specific post, I will set up a separate page on this blog just for the completed videos. So far I’ve done the rationale video in two parts, now these two on the periodic table, and more will follow as soon as possible. The next will be on the mining and refining of beryllium ore, then on glass blowing, and so on. I have materials (video, photos, etc.) for about 30 episodes already and will get more as student teams begin to complete projects. I will also post these episodes to YouTube but will have to cut each part in two since you can only do ten minutes at a time on YouTube. I also plan on creating a completely separate website just for these videos so that I can place my own metadata on them and upload them to Apple iTunes as podcasts. As these steps are completed, I’ll post information here.

Next week I travel to Philadelphia to present this project at the National Science Teachers Association (NSTA) conference. My presentation will be on Saturday, March 20 at 9:30 in Room D-17 of the Pennsylvania Convention Center. I hope to do a few posts from the conference. Looking through the program, I see several names I recognize among the presenters from my years of facilitating educational workshops for NASA, so it will be fun to see them again. I also hope to work out corporate sponsorship of this project, including funding, so that I can finally begin Phase II to have teams of student in Utah, Colorado, and Nevada start to create their own episodes of the mining and chemical manufacturing in their communities. It will be a very busy week getting ready for the conference. I’ll post again in a few days once all the uploading and links have been created to these videos.

    This has been a busy week for me here at the Chemical Heritage Foundation. On Tuesday, June 23 I presented The Elements Unearthed project at a Brown Bag Lunch here. It’s pretty informal; people bring their lunches and eat while the speaker presents. I had 20 people attend, which was very nice. I would have been happy with five!. After a couple of technology glitches  I switched to Plan B and everything went well. In addition to talking about the purpose of the project (which is to document the history, uses, sources, mining, refining, and hazards of the chemical elements and industrial materials through student-created podcasts (whew!)), I showed some short samples of the student videos created this last semester for glass blowing and synthetic diamonds. I also showed some animations with narration of a podcast episode I’m working on this summer on the history of atomic theory. You saw a sample image on the last post of Aristote’s hylomorphism. That’s just one frame of a whole animation. But just so that you can have a sneak peak at what will be posted to iTunes and YouTube by the end of August, here is the first video clip of the students’ work:

 

This is a clip edited and narrated by Alex Anderson, who also took the photos of the rejects at the end of the clip. Videotaping was done by Sam Comstock, Megan Parish, and Bernardo Martinez. My only contribution was some final tweaking of the video color balance and lighting to match up the two cameras and smooth up some transitions; otherwise, the editing is all Alex’s work.  This is a representative sample of the kind of work you’ll see when these episodes are finally posted. I’ll post the samples for Synthetic Diamonds and Aristotle/Empedocles next time.

    Here is the PDF version of my presentation, sans video clips:   Elements_Unearthed_Presentation_6-23-09

    After my presentation, Ron Brashear, the Director of the Beckman Center here at CHF, took me out to lunch. As we talked, I was surprised to find that we knew some of the same people. He had worked at the Huntington Library in California, researching Edwin Hubble’s letters and personal papers. As part of his research, he visited Mt. Wilson Observatory where Hubble did most of his work. I’ve been up there several times with the NASA Explorer School workshops that I did for JPL, and so we’ve both met some of the astronomers and docents at Mt. Wilson and we’ve both visited the Lowell Observatory in Flagstaff, AZ. It is a small world, as they say.

Intersecting Bubbles

Intersecting Bubbles

    I find, however, that as I have these opportunities to work in the science education and science history fields, that I increasingly meet the same people, or at least find that we have the same aquaintances. Academic and scientific circles become increasingly rarefied and specialized, but sometimes they intersect in interesting ways. One of the great privileges of my life has been to meet some of the best minds in several scientific disciplines, including space exploration, astronomy, and now science history. I’m not going to drop names here, but when comparing them to so-called “celebrities” I’ve met, the scientists are the truly great ones, the ones we should be holding up as heroes. My fellowship here at CHF has already helped me to make contact with some of these personal heroes and to at least intersect their circles, and that may be the best part of all for a science groupie like me.

    The other activity I’ve worked on is a Preliminary Proposal for an Informal Science Education grant from the National Science Foundation, which was due yesterday at 5:00. After writing with blazing speed (I hope it makes sense), I wrestled with NSF’s Fastlane submission system and finally hit the submit button a few minutes after 5:00, only to realize that I forgot to justify one of my budget entries – to provide stipends for time and equipment to the mentor teachers/schools of the participating teams. Hopefully that won’t be enough to kill it.  I am submitting the Summary Page and the Project Description here for your evaluation. I would appreciate any feedback you can give.

   Last week I drove 2300 miles from Utah to Philadelphia to take up my three-month residence at the Chemical Heritage Foundation. Today I’ll describe more about what CHF is, how I came to have this fellowship, and what I will be doing with it.

Entrance to Chemical Heritage Foundation, Philadelphia

Entrance to the Chemical Heritage Foundation, Philadelphia

   The Chemical Heritage Foundation was established as the Center for the History of Chemistry in 1982 at the University of Pennsylvania with support from the Americal Chemical Society (ACS) and later from the American Institute for Chemical Engineering (AIChE). In 1987 it incorporated as the non-profit National Foundation for the History of Chemistry, and in 1992 it was renamed the Chemical Heritage Foundation. In 1995, the foundation purchased the old First National Bank building in downtown Philadelphia, having outgrown its space at the U. of Pennsylvania. Today it has several divisions and research arms, including the Othmer Library of Chemical History which houses over 100,000 titles including journals, reference books, portraits, photos, oral histories, and even scientific instruments. It also houses the 6000 titles of the Roy G. Neville Historical Chemical Library, a collection of rare books from the 15th Century and later, some 400 titles being unique to this collection.  The Beckman Center for the History of Chemistry manages the research of visiting scholars and fellows at the library.

   In addition to the holdings in the library, CHF has museum spaces and exhibits and a convention center/meeting hall. The First National Bank building was rennovated and turned into museum space which opened last fall for the permanent exhibit called “Making Modernity,” which is a collection of instruments and artifacts that helped define the rise of chemistry as a science, with everything from samples of ancient Roman and medieval glassware to 20th Century pH meters, electron microscopes, and mass spectrometers. They also have changing exhibits such as “sLowlife,” a look at the adaptations and movements of plants; “The Whole of Nature and the Mirror of Art: Images of Alchemy” which is a series of photographic reproductions of illustrations from medieaval manuscripts; and “Transmutationa: Alchemy in Art” which displays paintings of alchemists by various artists. CHF also has traveling exhibits and the Ullyot Meeting Hall for conferences and conventions. It is a unique space for such meetings, since we are located right in the historical district of Phildelphia at 315 Chestnut St., diagonal to Carpenter’s Hall (where the First Continental Congress met in 1774) and just two blocks down from Independence Hall.

   The fellowships and travel grants managed through the Beckman Center are provided by the donations of individuals and 3rd party organizations. My fellowship is sponsored by the Societe de Chimie Industrielle (American Section), which has as its mission to provide better public understanding of the chemical industries, which is precisely what my project intends to do. I found out about this fellowship while researching grants about 18 months ago, and before that had not heard of CHF. I didn’t think I would qualify, since I don’t have a PhD or a disseration, but then I read the requirements for the Societe fellowship and found I might just qualify. I wrote a proposal and asked two people who know me and my work to write letters of recommendation, and sent the whole in by e-mail in Feb., 2008, thinking my chances were slim. When I received an e-mail from CHF  in April, 2008, I wasn’t able to read it at first because it came into my inbox as Chinese characters. I assumed it was the “thanks for your application we had many great applicants sorry we can’t accept all of them” and so on letter I’ve received before. I hit the reply button so I could get the Chinese translated into English and was amazed to find out this wasn’t a rejection letter at all. I had been selected! What remained was deciding when I would be here. My term of appointment is September 2008 through August 2009, but in discussions with my managers at MATC, they were not willing to let me take a sabbatical, especially in the fall when classes were beginning. Finally we compromised on this summer, the last three months of my fellowship term, when I would have fewer students to leave at MATC. They gave me such a difficult time about it, however, that I decided perhaps the time had come to leave MATC, which I have now done.

   During my three months here, I will be conducting background research into atomic theory and its origins and development through the Middle Ages until revived by Dalton and others. I’ll also be looking at the instrumentation and labware of alchemists and chemists through the ages, and anything else that might be useful (there are some great reference works here, and those oral histories). Basically, this will all become background material for The Elements Unearthed, with images and information used to provide historical depth and richness to our project. I hope to take the illustrations of labware that I find, for example, and turn them into 3D models and animations, perhaps re-create entire laboratories of famous chemists. For all this work, this is the place to be; no other library has so much information specifically related to this project, and this fellowship comes at an ideal point to move into Phase II. I am very fortunate to be here, and so far I am being treated very well indeed.

   My goal is to not only use my time here to finish editing the students’ projects into final video podcast episodes, but to create several new episodes based on the information and images I acquire here, so that about ten episodes will be ready for uploading at last by the end of August. I’m going to stuff as much information as I can find, as many photos as I can get, into a hard drive and use them over the next several years as the project develops. I can’t afford to waste any time, so I’ve set up a detailed research schedule and so far I’m following it well, with some wonderful new information about Democritus and Aristotle that I didn’t know before. I’ll share more of what that is and how my research is going in my next post.
