Zero Gravity Fluid Physics with Dr. Mark Weislogel

Dr. Mark Weislogel gives us a short tour at the Department of Mechanical & Materials Engineering at Portland State University. I greeted him with my cam and said, “show me stuff.” He tells us a little about some of the work he and his students are working on in zero-gravity fluid physics.

Watch Mark’s talk on PSU’s channel to learn more about being a Zero G Engineer:

    First comment. You know why? Because seeing “1 Comment” at the introduction frames the reader’s mind to believe the content is engaging enough for a comment. “0 comments” reduces the amount of real engagement because no one cares. So why would I let everyone know that I am ‘duping’ them? Because a greater number of readers (in this case, watchers) can now make up their own minds whether the content is valuable for them or not, by alleviating the readers from evidence of content quality based on comment numbers. Its marketing. Its what American culture taught me to look for—opportunities to inflate the consumer’s perception of a brand/product. Lying. We lie. Our culture has accepted it as a normal part of ‘guiding’ consumer appetites.
    So this comment has fulfilled 4 goals.

    1. Granting me “1 Comment” at the presentation of this post (generates higher click rate)
    2. Extrapolate the essence of the modern-American brand-consumer relationship in a negative (lying) light
    3. Taking the opportunity to give the readers an example of exploiting a marketing tactic transparently, so the reader can now contemplate if honesty and brand/product-inflation can co-exist congruently.
    4. Creating another opportunity for engagement over the topic of this tangent piece (spontaneity makes life interesting and fuller [same with comments within comments within comments!]).

    If you think these are ideas have truth, let me know. If you think they are ridiculous, please tell me why. This is an impromptu philosophical ponder that begs the thinker to develop their sense of ethics and cultural identity, and offers an example of a creative solutions that employs a basic marketing tactic, while still empowering the consumer (in this case content-consumers) to think as marketers, consumers, and emotional human beings.

    Note: I’m not editing this. The main idea is there. If some parts are muddy or sloppy, the idea is there. If you’d like me to clarify anything, or defend a presumption I have made, I’d be happy to! Just let me know with a comment. 😉

      I noticed a similar effect on the perceived value of an article with the published date. Peeps want to consume things that are current, regardless if it’s quality and timeless—like much of the information you publish.

      I’d suggest hiding the meta data that shows the comments and dates below your titles. Add this to your CSS to do that:

      .entry-header-meta{display: none;}

        Nice dude! I think I’ll use that trick when I am creating an informational, or how-to on a product. But being a content producer, I want to permit my audience and self to have the chronological context. It helps develop a narrative, and can motivate the producer to keep content current.
