June 10: How to make a rock (using Onshape)



3D printing and my experience with it

    I have a decent amount of experience with 3D printing, I own a printer and have made a bunch of models. I have printed replacement pieces for board games, stencils for D&D battle maps. Whenever there is a problem that requires a small plastic piece of very specific parameters I can make a solution. At one point the band had water bottles whose handles would snap off every other second so I went and made a file for replacement. It is safe to say that in any practical situation I can make something. There is one thing I have no clue how to do, and that is make something completely impractical, so incredibly pointless that it exist for the shear fact that it exist. Today I made a rock.

A quick discussion on the concept of rocks

    Rocks do not have a reason to exist, they did not decide that they wanted to be, they simply are. Rocks are not uniform they do not attempt to be perfect in any way, a rock that is a perfect cube is no rock at all. Rocks are subjective, they do not have any objective geometry. When you are asked to make a Triangular prism there are very few choices you get to make. When you are asked to make a cube there is a total of one choice you get to make, size. When you are asked to make a rock you have infinite choice. The rock is your oyster. A rock is a canvas from which any shape can be formed. 


    How to make a rock, A step by step guide

Preamble

    This will work in any cad program I chose Onshape because it was between that and Tinkercad and I wanted to try something I had not used before.

Step One: Shape

    When I was making my rock I needed a good shape to start with. Make any shape (I went with a rectangle) and extrude it some amount. 
    

Step Two: Shape (but more natural)

    The next step in the rock making process is to chop away little bits of the shape until it looks like a rock (I feel now is an important time to remind everyone that a rock can look like anything this step is impossible to mess up). By using the Chamfer tool or by making a plane at a weird angle and extruding it using the remove option you can remove material in a way that looks more rockish. Repeat this process until your rock looks desirably rocky.
    

Step Three: Rock

    After you have a rock like shape give it some personality you can add whatever you would like in this step I went with a little face so he can smile at me once he exist.





Final Thoughts

    This was a very fun project for me and I hope it was a very fun project for all of you who followed along. I feel for me it was good practice for me design something intentionally imperfect. I also got to learn a new software which is always a good time. Making rocks gets 10/10 from me.

June 6: Pseudoscience

Is SETI Pseudoscience?      Today in stem in society we broke out in to groups to discuss whether or not SETI (Search for Extraterrestrial Intelligence) is real Science or Pseudoscience. Our group was composed Roju Miller, Amelia Northam, Elsie Sheumaker, and Me, Austin Newman.      We used the following sites to build our discussion This is SETI's description on what they do.  https://www.seti.org/primer-seti-seti-institute   This is an article from Nasa about the search for extraterrestrial intelligence.  https://astrobiology.nasa.gov/news/technosignatures-and-the-search-for-extraterrestrial-intelligence/    This article is a debate on whether or not Fermi's paradox is disprovable and why SETI may be useful.  https://www.universetoday.com/139467/new-model-predicts-that-were-probably-the-only-advanced-civilization-in-the-observable-universe/#google_vignette     An article about a new experiment from SETI  https:...

Are CAFOs Ethical

Concentration Animal Feeding Operations or CAFOs are a way of farming animals by smushing them in to small spaces where they can barely move as much as turn around. In these horrible operations the animals are fed horribly and are mainly sustained on anti biotics. But are they Ethical???? Yes totally absolutely ethical 100 percent for real (for the record I was forced to take up this position) and here is why: It is efficient. In order to keep the same output we would have to use thousands times more land. Factory farmed cows produce less methane so if you think about it CAFO's are saving the planet. CAFO's cause cancer,... Which is actually a good thing because if more people get cancer then more people will be on the verge of death and resort to experimental treatment. If more people take experimental treatment it will become better until eventually we will have a cure. They are the only way we can get the meat production that we currently have in the US. If we were to shut d...
