    1. Water immobilization is a cool thing! The simplest way to accomplish it is by freezing. But can you think of how water might be immobilized (so to speak) at temperatures above freezing, say at 50°F (10°C)? Think Jell-O and a new process that mimics caviar and you have two methods that nearly stop water in its tracks.

      I learned that science and cooking is always connected. Even if we don't think about it in every day life like when water evaporates or freezes it is chemistry. But what I found most interesting that I learned is how water immobilization works, or to put it more simply the science behind Jell-O. When you add gelatin to water it traps the water molecules in place which creates the sort of liquid and solid hybrid we find with Jell-O.

    1. Comment

      I just wanted to let Columbia Gas of Ohio and Amanda DePerro know that not only is it poor etiquette to disable comments on posts (they obstruct customer feedback), but it's also pointless because people can just use tools like Hypothes.is to respond regardless.

    1. Gould, Jessica. “Teachers College, Columbia U. Dissolves Program behind Literacy Curriculum Used in NYC Public Schools.” Gothamist, September 8, 2023. https://gothamist.com/news/columbia-university-dissolves-program-behind-literacy-curriculum-used-in-nyc-public-schools.

      The Teachers College of Columbia University has shut down the Lucy Calkins Units of Study literacy program.

      Missing from the story is more emphasis on not only the social costs, which they touch on, but the tremendous financial (sunk) cost to the system by not only adopting it but enriching Calkins and the institution (in a position of trust) which benefitted from having sold it.

    1. Recommended Resource:

      I recommend adding this doctoral research article on developing open education practices (OEP) in British Columbia, Canada. The scholarly article is released by Open University, a U.K. higher education institution that promotes open education.

      Paskevicius, M. & Irvine, V. (2019). Open Education and Learning Design: Open Pedagogy in Praxis. Open University, 2019(1). DOI: 10.5334/jime.51

      A relevant excerpt from the article reveals the study results that show OEP enhances student learning:

      "Furthermore, participants reflected on how inviting learners to work in the open increased the level of risk and/or potential reward and thereby motivated greater investment in the work. This was articulated by Patricia who suggested “the stakes might feel higher when someone is creating something that’s going to be open and accessible by a wider community” as well as Alice who stated “students will write differently, you know, if they know it’s not just going to their professor.” The practice of encouraging learners to share their work was perceived by Olivia to “add more value to their work,” by showing learners the work they do at university can “have an audience beyond their professors.”"

    1. Eine neue Studie zur Entwaldung des kolumbianischen regenwalds beweist erstmals, der mit Abstand wichtigste Treiber der Entfaltung die Viehzucht ist Punkt sie ist um den Faktor 60 folgenreicher als der Anbau von Kokapflanzen. Frühere kolumbianische Regierungen haben Kokafarmer verfolgt, dabei aber den Landraub zu Viehzucht geduldet bzw.gefördert.

    1. Cattell, J. McKeen. “Methods for a Card Index.” Science 10, no. 247 (1899): 419–20.


      Columbia professor of psychology calls for the creation of a card index of references to reviews and abstracts for areas of research. Columbia was apparently doing this in 1899 for the psychology department.

      What happened to this effort? How similar was it to the system of advertising cards for books in Germany in the early 1930s described by Heyde?

    1. The lower courts consistently point to one paragraph in particular from the Heller decision. Nothing in the opinion, Scalia wrote, shouldbe taken to cast doubt on longstanding prohibitions on the possession of firearms by felons and the mentally ill, or laws forbidding the carrying of firearms in sensitive places such as schools and government buildings, or laws imposing conditions and qualifications on the commercial sale of arms.This paragraph from the pen of Justice Scalia, the foremost proponent of constitutional originalism, was astounding. True, the Founders imposed gun control, but they had no laws resembling Scalia’s list of Second Amendment exceptions. They had no laws banning guns in sensitive places, or laws prohibiting the mentally ill from possessing guns, or laws requiring commercial gun dealers to be licensed. Such restrictions are products of the 20th century. Justice Scalia, in other words, embraced a living Constitution.

    1. “Including open in the list of examples for educational leadership is important because it brings it to the forefront. When I went up for promotion, I took a risk because engaging in open practice was not listed as an example of educational leadership, but not everyone is going to do that. Whereas if it’s strictly laid out it raises the profile for those who haven’t thought about open education and also shows that it is valued by the university as being a form of educational leadership,”
