      Lois Gilbert Sutherland suggests using a card index system for multiple uses in the classroom including notes, administration, and general productivity.

      There are so many parallels from this to how people are using platforms like Obsidian, Roam Research, and Notion in 2022.

    1. Breitenbach, H. P. “The Card Index for Teachers.” The School Review 20, no. 4 (1912): 271–72.


      Apparently in 1912, the card index was little known to teachers... this isn't the sort of use case I was expecting here...

      The general gist of this short note is an encouraging one to suggest that instead of traditional grade books, which are still used heavily in 2022, teachers should use rolodex like cards for keeping attendance and notes on a student's progress.

      Presumably this never caught on. While some elementary teachers still use older paper gradebooks, many others have transferred to digital LMS platforms.

    2. Goutor recommends cross-referencing or linking ideas between cards "at the bottom of the note-card, as soon as the note itself is completed." Links shouldn't be trusted to memory and should be noted as soon as possible. Further he recommends periodically sorting through cards and adding adding additional cross references as one ruminates. While he indicates that cross-referencing may seem "cumbersome at first sight, experience will show that it enhances the usefulness of the card file when the time comes to retrieve the information it contains." (p32-33)

      Beyond this he doesn't indicate any additional benefits of creativity or serendipity that have been seen in similar treatises.

    3. Goutor breaks down the post-processing of notes into two phases: "coding" (tagging or categorization) and "cross-referencing". (p31).

    4. On page 24, Goutor cross references one note to another, but only does so at the level of the bigger book or text and not at the level of the individual notes themselves.

      Was this on purpose?

    1. IntertextsAs Jonathan Culler writes: “Liter-ary works are not to be consideredautonomous entities, ‘organicwholes,’ but as intertextual con-structs: sequences which havemeaning in relation to other textswhich they take up, cite, parody,refute, or generally transform.” ThePursuit of Signs (Ithaca, NY: CornelUniversity Press, 1981), 38.

      Throughout Rewriting: How To Do Things With Texts (Utah State University Press, 2006) Joseph Harris presents highlighted sidebar presentations he labels "Intertexts".

      They simultaneously serve the functions of footnotes, references, (pseudo-)pull quotes, and conversation with his own text. It's not frequently seen this way, but these intertexts serve the function of presenting his annotations of his own text to model these sorts of annotations and intertextuality which he hopes the reader (student) to be able to perform themselves. He explicitly places them in a visually forward position within the text rather than hiding them in the pages' footnotes or end notes where the audience he is addressing can't possibly miss them. In fact, the reader will be drawn to them above other parts of the text when doing a cursory flip through the book upon picking it up, a fact that underlines their importance in his book's thesis.


      This really is a fantastic example of the marriage of form and function as well as modelling behavior.

      Preliminary thoughts prior to reading:<br /> What advice does Boice give? Is he following in the commonplace or zettelkasten traditions? Is the writing ever day he's talking about really progressive note taking? Is this being misunderstood?

      Compare this to the incremental work suggested by Ahrens (2017).

      Is there a particular delineation between writing for academic research and fiction writing which can be wholly different endeavors from a structural point of view? I see citations of many fiction names here.

    1. Each type of index card should have a dif-ferent color, and should include in the top right corner abbre-viations that cross-reference one series of cards to another,and to the general plan. The result is something majestic.

      Finally a concrete statement about actively cross-linking ideas on note cards together!

    1. German publishers send out so-called book cards to book shops along with their newreleases. On them, bibliographic information is printed. Those book cards are also in postcardsize, i.e. A6, and their textual structure allows for them to be included in the reference filebox.

      Automatic reference cards!

      When did they stop doing this!!!

      an example within this essay of a cross reference from one note to another showing the potential linkages of individual notes within one's own slipbox.

    3. the slips by the topicalheadings. Guide cards are useful to gdicate the several head-ings and subheadings. Under each heading classif the slipsin writing, discarding any that may not prove useful andmaking cross references for notes which may be needed foruse in more than one lace. This classification will reveal,almost automatically, wiere there are deficiencies in the ma-terials collected which should be remedied. The completedand classified collection of notes then becomes the basis ofcomposition.

      missing some textual context here for full quote...

      Dutcher is recommending arranging notes and cards by topical headings in a commonplace sort of method. He does recommend a sub-arrangement of placing them in logical order for one's writing however. He goes even further and indicates one may "make cross references for notes which may be needed for use in more than one place." Which provides an early indication of linking or cross linking cards to multiple places within in one's card index. (Has this cross referencing (linking) idea appeared in the literature specifically before, or is this an early instantiation of this idea?)

      • Otlet and Goldsmith were precursors as well

      four figures in his research: - Patrick Gattis - biologist, architect, diagrams of knowledge, metaphorical use of architecture; classification - Paul Otlet, Brussels born - Wilhelm Ostwalt - nobel prize in chemistry - Otto Neurath, philosophher, designer of isotype

      Paul Otlet

      Otlet was interested in both the physical as well as the intangible aspects of the Mundaneum including as an idea, an institution, method, body of work, building, and as a network.<br /> (#t=1020)

      Early iPhone diagram?!?

      (roughly) armchair to do the things in the web of life (Nelson quote) (get full quote and source for use) (circa 19:30)

      compares Otlet to TBL


      Michael Buckland 1991 <s>internet of things</s> coinage - did I hear this correctly? https://en.wikipedia.org/wiki/Internet_of_things lists different coinages

      Turns out it was "information as thing"<br /> See: https://hypothes.is/a/kXIjaBaOEe2MEi8Fav6QsA


      sugane brierre and otlet<br /> "everything can be in a document"<br /> importance of evidence


      The idea of evidence implies a passiveness. For evidence to be useful then, one has to actively do something with it, use it for comparison or analysis with other facts, knowledge, or evidence for it to become useful.


      transformation of sound into writing<br /> movement of pieces at will to create a new combination of facts - combinatorial creativity idea here. (circa 27:30 and again at 29:00)<br /> not just efficiency but improvement and purification of humanity

      put things on system cards and put them into new orders<br /> breaking things down into smaller pieces, whether books or index cards....

      Otlet doesn't use the word interfaces, but makes these with language and annotations that existed at the time. (32:00)

      Otlet created diagrams and images to expand his ideas

      Otlet used octagonal index cards to create extra edges to connect them together by topic. This created more complex trees of knowledge beyond the four sides of standard index cards. (diagram referenced, but not contained in the lecture)

      Otlet is interested in the "materialization of knowledge": how to transfer idea into an object. (How does this related to mnemonic devices for daily use? How does it relate to broader material culture?)

      Otlet inspired by work of Herbert Spencer

      space an time are forms of thought, I hold myself that they are forms of things. (get full quote and source) from spencer influence of Plato's forms here?

      Otlet visualization of information (38:20)

      S. R. Ranganathan may have had these ideas about visualization too

      atomization of knowledge; atomist approach 19th century examples:S. R. Ranganathan, Wilson, Otlet, Richardson, (atomic notes are NOT new either...) (39:40)

      Otlet creates interfaces to the world - time with cyclic representation - space - moving cube along time and space axes as well as levels of detail - comparison to Ted Nelson and zoomable screens even though Ted Nelson didn't have screens, but simulated them in paper - globes

      Katie Berner - semantic web; claims that reporting a scholarly result won't be a paper, but a nugget of information that links to other portions of the network of knowledge.<br /> (so not just one's own system, but the global commons system)

      Mention of Open Annotation (Consortium) Collaboration:<br /> - Jane Hunter, University of Australia Brisbane & Queensland<br /> - Tim Cole, University of Urbana Champaign<br /> - Herbert Van de Sompel, Los Alamos National Laboratory annotations of various media<br /> see:<br /> - https://www.researchgate.net/publication/311366469_The_Open_Annotation_Collaboration_A_Data_Model_to_Support_Sharing_and_Interoperability_of_Scholarly_Annotations - http://www.openannotation.org/spec/core/20130205/index.html - http://www.openannotation.org/PhaseIII_Team.html

      trust must be put into the system for it to work

      coloration of the provenance of links goes back to Otlet (~52:00)

      T.J. Johnson and colleagues studied several mixer designs by fabricating a series of slanted wells within a microchannel using a UV excimer laser. These wells generated a high degree of lateral transport within the channel to help induce rapid mixing between two confluent streams undergoing electroosmotic flow.

      The authors demonstrated chaotic mixing in a twisted pipe with a circular cross-section.

    3. 23. We qualify the mixing as thorough when the fluorescence appears uniform to within the resolution (∼2 μm) and sensitivity (down to variations of ∼5% of the maximum intensity) of our microscope.

      Because there are many possible solutions to a problem; it is important to choose the design requirements and success criteria for the proposed solution. Here the authors describe their design criteria for thoroughly mixing a solution.

    1. 16. We made the master structures with two-step photolithography in SU-8 photoresist: The first layer of photolithography defined the channel structure; the second layer defined the pattern of ridges. The pattern of ridges was aligned to lie on top of the channel structure in the first layer. We measured the dimensions of the channel and the ridges using a profilometer. We made molds of the structure in PDMS. To close the channel, we exposed the PDMS to a plasma for 1 min and sealed it to a glass cover slip.

      Here the authors describe the exact steps that they use to create the devices. The techniques (photolithography) and materials (PDMS) described are commonly used in the fabrication of microfluidic devices.

      This paper shows an alternative form of fluid mixing in microfluidic channels. This method uses curved channels with serpentine geometry to mix fluids by generating chaotic flow similar to the one presented in this paper.

      This article outlines a common use of microfluidics, that is the miniaturization of assays to run many of them in parallel at the same time ((high throughput assays). This paper addresses one of the main problems in assay miniaturization, which is efficient mixing of assay components.

    1. In an ever-increasing sphere of digital print, why can't publishers provide readers a digitally programmed selection of footnote references in texts?

      This digital version of Annie Murphy Paul's book has endnotes with links from the endnotes back to the original pages, but the opposite links from the reading don't go to the endnotes in an obvious way.

      I'd love to be able to turn on/off a variety of footnote options so that I can see them on the pages they appear, as pop up modals, or browse through them in the end notes after-the-fact as I choose. This would allow me to have more choice and selection from a text based on what I want to get out of it rather than relying on a publisher to make that choice for me.

      Often in publishing a text written for the broad public will "hide" the footnotes at the end of the text in unintuitive ways where as more scholarly presses will place them closer to their appearance within the text. Given the digital nature of texts, it should be possible to allow the reader to choose where these items appear to suit their reading styles.

      Hu et al have embedded permanent magnets into the soft robot that allow for the generation of a magnetic field. This actuation method allows for faster movement, but Hu's top speed (213 mm/s) is still one-fourth of the top speed reported for the presented robot.

      Rogóz et al. utilizes liquid crystalline elastomers that change shape under light; specifically, a continuous wave green laser beam scans the robot body and a traveling deformation is observed. The robot can perform difficult tasks like walk up a slope and squeeze through a narrow slit, however it is hindered by damage from burning along the laser beam center.

    6. 22. E. Wang, M. S. Desai, S.-W. Lee, Light-controlled graphene-elastin composite hydrogel actuators. Nano Lett. 13, 2826–2830 (2013).

      Wang et al. chooses to use light-driven hydrogel as it allows for wires and electrodes to be avoided, and light can be controlled more easily than other actuation methods. However, the crawling gait was generated by curling and uncurling after exposure to a near infrared laser. This mechanism poses issues due to the constant laser repetition required to move the device.

      In order to mimic a hop-like pattern, Kagawa et al. have used the movement style and foot path of cockroaches. Unlike the single-leg and later implemented double-leg utilized in this paper, Kagawa uses a four-legged walking machine with dimensions of 2 in x 1 in (50.8 mm x 25.4) which is significantly larger than this 10 mm x 15 mm soft robot.

      Wang et al. employed worm movement patterns to show proper movement of their soft robots. Specifically the looping gait, requires front and back leg anchoring for sequential contracting and stretching. This differs from the four main postures used in this wave-like gait pattern which include aerial, front-touching, back-touching, and both-touching.

The authors combined a pressure sensor, ring oscillator, and an ion gel-gated transistor to form an artificial mechanoreceptor. Their artificial nerve can collect pressure information from 1 to 80 kilopascals. It transforms the pressure information into action potentials ranging from 0 to 100 hertz. Their afferent nerve can detect movement, simultaneous pressure inputs, and distinguish braille characters.

Their DiTact system was able to mimic human tactile perception with slow/no frequency oscillation in the absence of pressure stimulation and increasing frequency with increased with pressures applied to the device. Overall, the device was capable of evoking action potentials at frequencies up to 200 Hz for prolonged intervals.

The glove monitors live finger movement and registers distributed pressure along the entire length of the finger. The sensory skin is made of elastic materials and does not impede hand movement. Capacitive pressure sensors with stretchable gold thin-film electrodes and porous silicone foam display high sensitivity across the dynamic pressure range of human skin. Pressure sensors in the glove are distributed along the grasping region of the finger, with strain sensors along the back of the finger. The glove is successfully used in grasping and manipulation tasks.

    3. This condition is based on the following characteristic values: U < 100 cm/s, l ∼ 0.01 cm, ν = 0.01 g/cm·s. For channels, l is typically taken to be the smallest cross-sectional dimension.

      Given these values, the Reynolds number for the microchannel flow described in this work would be less than 100, which indicates laminar flow and dominant viscous forces. It is nearly impossible to generate chaotic flows, which facilitates mixing, in microchannels.

      Newman et al.'s model predicts the size of the hole in the Antarctic ozone layer based on the level of ozone-depleting substances in the atmosphere.

      Their model predicts that the hole is expected to fully recover around 2068 because the levels of ozone-depleting substances have been declining.

    2. 24. S. Solomon, D. Kinnison, J. Bandoro, R. R. Garcia, J. Geophys. Res. 120, 7958–7974 (2015).

      Solomon et al. used a model to identify key factors influencing chemically induced ozone depletion.

      For example, they found that polar ozone loss is particularly sensitive to temperature and the presence of sulfate aerosols from volcanic eruptions.

      The model's predictions are in good agreement with measured ozone-abundance data.

    3. 13. J. Kuttippurath et al., Atmos. Chem. Phys. 15, 10385–10397 (2015).

      Kuttippurath et al. reported that from 2004 to 2013, the level of ozone-depleting substances was relatively stable. Thus, they conclude that naturally occurring climate variations produced the year-to-year variations in the ozone hole depth.

    4. 12. S. Solomon, Rev. Geophys. 37, 275–316 (1999).

      In this review paper, Solomon explains that human-made chlorofluorocarbons (CFCs) are the primary cause of the hole in the ozone layer.

      Also, the paper emphasizes that more ozone depletion occurs in the Antarctic and Arctic regions due to surface chemistry on cold polar clouds.

    5. 10. J. Kuttippurath et al., Atmos. Chem. Phys. 13, 1625–1635 (2013).

      Kuttippurath et al. reported signs of ozone-layer recovery by using September-to-November averaged data collected from 1979 to 2010.

      They attributed these signs of recovery to the reduction in ozone-depleting substances.

    6. 9. M. L. Salby, E. Titova, L. Deschamps, Geophys. Res. Lett. 38, L09702 (2011).

      Salby et al. demonstrate that naturally occurring changes, or variability, in the ozone layer must be taken into account to observe human-induced changes.<br> Here, they report that after accounting for the naturally occurring changes, a trend of increasing ozone levels is observed.

      Salby et al. look for signs of ozone healing using September-to-November averages, but the current paper by Solomon et al. uses data from September when there is less variability.

    7. 7. T. G. Shepherd et al., Nat. Geosci. 7, 443–449 (2014).

      Shepherd et al. show that in order to predict the effects of human-induced climate change, models must include more than just surface temperature conditions.

      These models must also account for uncertainties arising from circulation, or the movement of air, within the atmosphere.

      The 2014 assessment concludes that nearly half of the improvement in stratospheric ozone levels since the year 2000 is due to a reduction in ozone-depleting substances.

    4. L. Navarro-Martín et al., PLOS Genet. 7, e1002447 (2011).

      Navarro-Martín et al. study the mechanism underlying temperature-dependent sex determination in the European sea bass fish. They show that DNA methylation at the promoter of a gonadal aromatase (estrogen-making protein) is increased at high temperatures, causing female fish to masculinize.

      This supports the idea that there are many epigenetic mechanisms that can govern temperature-dependent sex determination across species and environments.

    8. I. W. Deveson et al., Sci. Adv. 3, e1700731 (2017).

      Deveson et al. reveals that a single intron change for two epigenetic-related protein transcripts (JARID2 and JMJD3/KDM6B) is specifically induced in high temperature sex reversal in female bearded dragons as opposed to normal bearded dragons. Authors propose that the intron retention changes JARID2 and JMJD3/KDM6B function and overcomes genetic sex-determining with different gene expression at extreme temperatures.

      This study provides evidence that ‘Alalā, an endangered native bird species in Hawaii, displays seed dispersal behaviors and promotes seed germination of various native plants. Based on these results, the authors suggest that ‘Alalā can contribute toward the restoration of native fruiting plants in Hawaiian forest communities.

    2. E. Burgos et al., J. Theor. Biol. 249, 307–313 (2007).

      Nestedness can contribute toward the robustness of a network. If species that share fewer interactions are the first to go extinct, the remaining mutualistic system has a greater chance of survival. The authors also calculate a coefficient as a parameter of a network’s robustness.

    3. H. A. Mooney, E. E. Cleland, Proc. Natl. Acad. Sci. U.S.A. 98, 5446–5451 (2001).

      Mooney and Cleland describe the evolutionary consequences of invasive species on the invaders themselves and on native species. Modifying behavior to adapt to a new environment, competing for similar resources, predation, or creating hybrid progeny by breeding with native species are just a few examples.

    4. N. Blüthgen, F. Menzel, N. Blüthgen, BMC Ecol. 6, 9 (2006).

      Previously, the majority of network analysis was qualitative. Blüthgen et al. introduce two quantitative measurements that use the frequency of interactions to describe specialization at the species level and across a network.

    5. E. L. Rezende, J. E. Lavabre, P. R. Guimarães, P. Jordano, J. Bascompte, Nature 448, 925–928 (2007).

      The phylogenetic or evolutionary relationship between species can predict the types and quantity of interaction patterns they exhibit in a network. Using a simulation of extinction events, the authors also demonstrated that the extinction of one species can result in the extinction of other species that are evolutionarily related.

    6. A. de Almeida, S. B. Mikich, Oikos 127, 184–197 (2018).

      The authors merged data sets from multiple studies investigating fruit-frugivore interactions and illustrated that most networks across various neotropical areas were significantly nested and modular. The authors also concluded that combining results from different studies can be useful for analyzing the ecological structures of broad regions and supporting conservation efforts.

    7. C. G. Chimera, D. R. Drake, Biotropica 42, 493–502 (2010).

      In contrast to Foster, Chimera found that introduced birds in Hawaii dispersed predominately the seeds of non-native plants. Possible explanations could be that the non-native plants produce larger fruit that are more abundant and have a smaller seed size. These qualities are more enticing to birds and enhance the fruit's chances of getting eaten and its seeds later deposited.

    8. J. T. Foster, S. K. Robinson, Conserv. Biol. 21, 1248–1257 (2007).

      Foster and colleagues investigated how often introduced fruit-eating birds on the islands of Hawaii consume and disperse seeds from native plants versus seeds from exotic plants. They found that seeds from native plants made up the majority of the introduced bird species’ diets. This supports the potential of introduced bird species playing a role in the conservation efforts of native habitats.

      The Anthropocene is defined as the epoch or geological time when human activity significantly impacted the global environment. Based on the criteria for defining a new epoch and supporting geological evidence, the authors propose two possible dates to mark the beginning of the Anthropocene: 1610 and 1964.

      This review summarizes current research on plant-pollinator networks, stressing the need to include more studies in tropical areas. Tropical areas have a richer diversity in plants and animals than non-tropical areas, resulting in the several network patterns such as low connectance and higher modularity. However, these patterns are overlooked when tropical areas are not equally analyzed, limiting accurate understanding of this relationships.

      By simulating the network patterns between plants and pollinators, the authors demonstrated that plants were more resistant to extinction with the removal of specialized pollinators versus generalized pollinators. Specialized pollinators only interact with a few plant species, whereas generalized pollinators interact with a larger range of plant species. When a generalized pollinator is lost, more plants are affected.

      This study provides evidence that ‘Alalā, an endangered, native bird species in Hawaii, displays seed dispersal behaviors and promotes seed germination of various native plants. Based on these results, the authors suggest that ‘Alalā can contribute towards the restoration of native fruiting plants in Hawaiian forest communities.

      The authors merged data sets from multiple studies investigating fruit-frugivore interactions and illustrated that most networks across various neotropical areas were significantly nested and modular. The authors also concluded that combining results from different studies can be useful for analyzing the ecological structures of broad regions, and supporting conservation efforts.

      This research examined the sizes and locations of plastic particles found in the world's oceans. When plastic objects in the ocean are exposed to sunlight, they tend to break up into small particles because sunlight weakens the plastic structure and waves provide mechanical force. The small plastic particles are quite durable. Most of the plastic debris recovered and measured during this study was about 2 mm in diameter. The total amount of plastic in the ocean estimated by this study was less than predicted from plastics production and input rates. The "missing" plastics were hypothesized to be removed through one or more of the following processes: shore deposition (being deposited on shore somewhere), nano-fragmentation (breaking up into very small pieces), biofouling (small organisms grow on the plastic particles, and the plastics become heavy enough to sink), and ingestion (being consumed by marine life). The pathway and fate of the "missing" plastic is unknown.

      When sea ice forms, it traps particulate matter from the water column such as microplastics. When sea ice melts, the particulate matter is released back into the ecosystem. This study examines the concentration of microplastics in Arctic Sea ice and finds that sea ice contains high concentrations of microplastics and other manmade particulates. Melting sea ice has the potential to release large amounts of microplastics back into the ocean.

      An ocean gyre is a circular ocean current formed by Earth’s wind patterns and rotation. The area in the center of a gyre tends to be very calm, and the circulation patterns of the currents draw debris into the stable center, where it becomes trapped. The debris is composed of objects both manmade and natural (i.e., driftwood). Many kinds of sea life live on and near the debris, such as gooseneck barnacles. Goldstein and Goodwin examined the digestive tracts of gooseneck barnacles to see if the barnacles consumed any plastics. One-third of the 385 barnacles examined had plastic particles present in their digestive tracts, and larger barnacles tended to contain more plastic particles. The effects of plastic particle ingestion on the ecosystem are still unknown.
