Rheology, Theology, Salvador Dali, and God

o, this is not going to be one of those children’s games, such as “One of These Things is Not Like the Other” that you might still see on Sesame Street. Instead, rather than highlighting their dissimilarities, I will try to draw a connection between the very diverse elements listed in the title of this article.
Rheology As you probably already know, rheology is the science that studies the deformation and flow of materials. Theology is a way of thinking, or a belief system—like an ideology, religion, etc. Even though the derivation of both words may be traced back to the Greek words rheos (flow, stream), theos (God, god), and ology (a branch of learning), they are ‘seemingly’ two very different branches of learning.1,2 Now, your computer, which thinks it knows everything, will certainly confuse the two. Therefore, I caution you that the first time that you type the word ‘rheology’ using a word processer do not trust spell check to get it right. Invariably it will change the word to ‘theology’. At least that’s been my experience. Like Sgt. Phil Esterhaus (played by the late, Michael Conrad) said at the end of every TV episode of Hill Street Blues, “Let’s be careful out there.” In fact, go ahead and add the word ‘rheology’ to your software program’s dictionary right now. I will wait. As you will see in the next section, the connection between the
The Persistence of Memory (Spanish: La persistencia de la memoria; Catalan: La persistència de la memòria) is a 1931 painting by artist Salvador Dalí.
two words runs so much deeper than the similarity of their spelling. The rheological realm covers a continuum that extends from purely viscous materials that deform or flow irreversibly (e.g., water, mineral oil, etc.) to purely elastic solids, that spring back unchanged (a steel ball, for example)—see Figure 1.3 Pure liquids exhibit Newtonian rheology and their viscosity remains constant regardless of the amount of stress applied. Most, if not all, materials are viscoelastic, which means that they contain varying degrees of both properties. Take, for example, Silly Putty (Dow Corning 3179 dilatant compound). Under low shear stress it exhibits viscous behavior (will flow irreversibly) and elastic behavior under high shear (it will bounce or break; thus, behaving very much like a solid)—see Figure 2.4 So, technically speaking, selling Silly-Putty as the “real solid-liquid” is truth-in-advertising.5 Figure 1.

It is very difficult to imagine a steel ball being elastic in nature. Under normal conditions, certainly no one can perceive any deformation; at least not with the naked eye. That is because the relaxation time, following removal of the stress, is immediate. It is equally difficult to conceive that it contains any viscous component whatsoever. At the opposite extreme, the viscous behavior of window glass, which actually is a super cooled liquid at room temperature, is also very difficult to observe. This time it is because the deforming force of gravity on a vertical windowpane takes decades to occur.5 At this point, the connection to theology enters the discussion. Here goes…
Theology Many years ago, I read about the Deborah Number.6 (No, I did not forget to mention Deborah in the title. I purposely left her out so that you did not jump to the conclusion that there was something sordid going on between her and Salvador.) Unlike the Reynolds Number,7 another dimensionless value that Chemical Engineers use to describe the rheological mechanics of fluid flowing through pipes, hoses, and other conduits, the Deborah Number has a theological aspect. Yes, I mean theological—it is not a typo. The Deborah Number takes the science of rheology to a higher (theological) level. In 1964 Markus Reiner called upon the bible verse, “The Mountains flowed before the Lord,” contained in a song by prophetess Deborah (Judges 5:5) celebrating a victory over a powerful enemy. Reiner used that biblical reference to name the phenomena that given sufficient time even the most rigid or unyielding materials, like a mountain, will flow. Deborah Number =
Characteristic relaxation time of material (1) Time scale of observation
Basically, the above ratio shows that the rheology of a material depends upon two fundamentally different characteristic times: 1. The intrinsic time it takes for a material to adjust to applied stress. 2. The time needed to run the experiment. Therefore, the way a material flows is not merely a fundamental nature inherent in the material itself. It also has to do with the stress it is under and the length of time it takes to respond. A small Deborah Number typifies a viscous fluid with Newtonian flow properties. A high Deborah Number exemplifies a non-Newtonian material. The higher the Deborah Number the more elastic or solid-like the material is. If the experiment is

designed to see how something responds when you whack it with a hammer, the time scale of observation (the denominator) will be very short and will obviously tend to increase the Deborah Number. Conversely, a material with a longer relaxation time will have a higher Deborah Number also. To reiterate, all materials are virtually viscoelastic. If the Deborah Number is < 1, the stress is proportional to the viscosity times the shear rate and the material behaves most like a viscous liquid. If the Deborah Number is > 1, the stress is proportional to the modulus of rigidity times the strain and the material behaves more like an elastic solid. If the Deborah Number is ≈ 1, the material is very viscoelastic.5 There is one more dimensionless number used by rheologists that I merely want to mention. That is the Weissenberg Number. It helps define the viscoelastic nature of polymeric solutions. If you are a cosmetic chemist formulating at the bench, you have probably seen the ‘Weissenberg Effect’ yourself without knowing that there is a term for it (see Figure 3).8 Weissenberg number = Relaxation time X Deformation rate9 (2) Next, one (me) may use both the Deborah Number and the Pitch Drop Experiment to make the comparison to, and connection to, Salvador Dali (the surrealist painter from Catalonia, Spain) and God.10-13
The Pitch Drop Experiment My entire thought process on this subject started when I read about a momentous occasion in science that occurred in August 2013. It was the extremely exciting news (a bit of sarcasm) that another drop of pitch dripped! The “Pitch Drop Experiment,” for those few who still might not know (more sarcasm), is the longest running scientific experiment in the world. (To be completely honest, that alone was new Figure 3. The Weissenberg Effect. From http://www.rwe.com/web/cms/en/55196/ news to me.) It is even in the Guinness Book of World Records. rwe-dea/know-how/wietze-laboratory/. Briefly, back in 1927, Thomas Parnell, a physics professor at the University of Queensland in Australia, melted some pitch (a.k.a. bitumen or asphalt) and poured it into a funnel. The point he was trying to make is that even something as rock-hard as bitumen will, eventually, flow like a liquid. Maybe this was already known, but he set up this experiment as a teaching tool to demonstrate it nonetheless. Although not readily obvious, pitch, like Silly Putty, is viscoelastic. Both will shatter if you hit them with a hammer. However, on the opposite end of the continuum, the fluidity of pitch takes a lot longer to observe. One can observe the deformation of Silly Putty due to the force of gravity in a matter of minutes. It takes a single drop of bitumen nearly a decade to form and drop. And if you blink, you might miss it when it does. A similar experiment is running at Trinity College in Dublin, Ireland, but the pitch is somewhat different and, dare I say, a little bit runny. That experiment did not start until October 1944, and when it dripped on July 11, 2013, it was the first time a pitch drop was successfully filmed. If you are interested, the video is available on many websites. It is certainly Figure 4. possible that perhaps a few shared pints of Guinness between rheologists The Pitch Drop Experiment. might be at the root cause of this obsession with pitch. The viscosity of water at 20 ºC is about 10-3 Pa·s. Taking into consideration that the viscosity of pitch is temperature dependent, scientists calculated that the average viscosity of the pitch used in this experiment to be on the order of 108 Pa·s. Crazy as it may seem (to me anyway), the effective viscosity of the Earth is on the order of 1020 Pa·s.10 Who thinks of measuring such things? It’s a far cry from using a Brookfield RVT viscometer with spindle number 4 at 20 rpm at 25 ºC for 1 minute to find out if my shampoo is within specification or not. For comparison purposes, my shampoo of 8,000 centipoise (cP or cps) may be converted to 8 pascal seconds (Pa•s). Isn’t it interesting that both Pitch Drop Experiments began decades before Markus Reiner invoked the Prophetess Deborah in 1964? (Continued on page 6)

(Continued from page 5)
When I first heard the biblical phrase, “The Mountains flowed before the Lord.” I never thought it implied volcanic eruptions and molten lava flow, or motion of the earth’s tectonic plates. Only that perhaps nothing is permanent and a faith that God can indeed move mountains and vanquish even the most formidable of foes. Used in the context with which Markus Reiner intended, I understood he created the Deborah Number to try and explain the inherent rheological properties of materials. I wondered if the watches in Salvador Dalí’s paintings are not melting due to high temperature, but simply symbolic that everything eventually, given sufficient time, will flow before the Lord. Did Dalí study the science of rheology? Did he know about the Deborah Number; or, was he at least familiar with the phrase quoted from the bible? According to Wikipedia, the symbolism of the melting watches “suggest that time is relative and not fixed.”14 In any case, Dalí was also fascinated with the new science of quantum mechanics and was “inspired by Werner Heisenberg’s Uncertainty Principle.”

God Forget for a moment whether you are an atheist, agnostic, or true believer. Whatever your perceptions or beliefs about God may be, it is irrefutable that we do not know all there is to know about everything. We are severely limited. Maybe one day we won’t be. Our time here on earth is finite. We won’t be around long enough to observe and measure the time it takes for some materials (like mountains) to deform under stress and relax again. But maybe there is some unknown constant that always was and always will be— even long after we are all gone. The time it took to observe a pitch drop drip seems long enough. So then, how inconceivably long might it take a mountain to flow; how many eons? Does time and space as we measure it even continue to exist? How does God measure time? What value do you plug into the denominator of the Deborah Number equation? If a tree falls in the woods and no one is there to hear it, does it make a sound? If a drop of pitch drips and there is no one there to observe it, does it actually drip? Which gets me to thinking about Schrödinger’s Cat and the “observer effect.” Best to save that for another day. So you see, this really is an article about the esoteric pitch drop experiment. If I gave that away in the title, who would read all my musings that it prompted? No doubt you would read about that insignificant slow-moving drop observation and either disregard it or, come away stimulated by your own thoughts and ideas it generated. Esoteric, maybe. But insignificant? I guess not. It seems to be at the center of everything. Well, it doesn’t explain the meaning of life, but at least it is at the center of this article. In conclusion, if you want to become closer to God, be sure to attend the two-day NYSCC Rheology Symposium, March 19-20, on the campus of Princeton University. Be there or be square wicked.
