2021 Paper Group

A few friends in my discord do a weekly ‘paper’ discussion group (read: like a book club but nerdier) & I figured it’d be nice to record some comments from the papers selected over time & maybe revisit to see if there’s further development on what we’ve discussed previously. I put a backlog of the papers we’ve discussed at the end and future papers and notes to the top of the next section.

  • Time Compression in Virtual Realityhttps://brill.com/view/journals/time/aop/article-10.1163-22134468-bja10034/article-10.1163-22134468-bja10034.xml
    • An interesting topic which I think will have real findings in the years to come. The biggest criticism was that the sample size was really quite small & the findings had quite a lot of variance which makes it hard to put much weight in the conclusions.
    • The authors discuss this and provide a few possible ways to interpret their results (which is that VR does have a notable ‘time compression’ effect during the experience of VR) but they also point out a number of other controls or modifications to their experimental design which it seems would provide more insight than the current paper.
    • Overall interesting as a topic and from an experimental design but a lot of variables which may skew results.
  • Profunctor optics, a categorical updatehttps://arxiv.org/pdf/2001.07488.pdf
    • Contributes some of the following computer science items: an abstraction to represent optics, expression of existing structures as mixed optics, new family of optics, unified definition of lenses which encompasses existing discrete definitions, and a lot of other items which build on prior results.
    • Interesting to programmers that care about optics.
  • Human hand as a powerless and multiplexed infrared light source for information decryption and complex signal generationhttps://www.pnas.org/content/118/15/e2021077118
    • TL;DR – human hands generate IR light in a few interesting ways. This is notable because it is done without electricity, etc, so it may have uses in places where electricity is not readily available or as part of designed systems to leverage the infrared properties of the hand; the paper investigates using this for signal generation, encryption systems, and other applications.
    • Our general opinion of the paper was that it highlighted some really cool concepts but the execution was somewhat lackluster. Writing of the paper was kinda rough. Some super cool potentials -such as the wrist-based grating offering 3^5 bits of signaling.
    • Quote of the paper: “Moon is another natural light source that helps us see things during the night.”
    • Hope to see future citing of the paper with more interesting applications.
  • Observation of Gravitational Waves from a Binary Black Hole Merger https://journals.aps.org/prl/pdf/10.1103/PhysRevLett.116.061102
    • This was a really fun paper from 2017. I had heard about gravitational wave detections from LIGO when they were first announced as it was a pretty notable event. None of our group had read the paper and, when selecting a paper for this week I came across it in a list of frequently cited papers and decided to give it a go. On the whole we agreed it was an interesting paper, well written, and conveyed the significance and details of the detection well. Towards the end there was a big discussion about the assumptions used in the paper being both substantial and under acknowledged; on doing some follow-up research it looks like that was one of few criticisms of the paper which made its way in to a few journals — the assumptions held up and were logical but they were, never-the-less, still assumptions.
    • A good paper for those interested in what gravitational waves are, how they can be caused and how they are detected.
    • A really notable takeaway for me was the way the waves were predicted and modeled before any detections existed and not only were apparently quite accurate but also had modeled a variety of celestial phenomena (colliding black holes, stars colliding with black holes, colliding white dwarfs, etc. Very cool stuff!
  • The Attentional Cost of Inattentional Blindnesshttps://pubmed.ncbi.nlm.nih.gov/17433282/
    • Interesting paper about some phenomenons tied to attention and missing stimulus when focused on other tasks. The paper does 5 experiments in a similar vein to the familiar gorilla/basketball experiment. The biggest highlight appears to be that when focusing on something an unusual/unexpected events happen, even subconsciously, it costs some degree of attention.
    • Interesting question – what would this look like in an fMRI? Would also be interesting to see other similar experiments in different circumstances or with larger groups of people.
