Braided Corona Star, Maria Sinayskaya || 8 units (7.50 x 7.50, square) || Instructions

this paper was awful and it basically was straight up wrapping paper glued to like. cardstock or something. i had to get rid of it straightaway

Masquerade, Ekaterina Lukasheva || 2-8, 10, 30 units (7.50 x 7.50, square) Instructions in Ekaterina Lukasheva’s Modular Origami Kaleidoscope

I’ve made the complete set of deltahedra before from an analogous unit which is assembled in the same configuration, but obviously this one has the added patterns.

Assembling in this manner has two key differences from the usual spiked-face configurations we see in many kusudamas:

Each unit represents a pair of faces, instead of an edge

You can, and often have to, mix the handedness of the units.

The combinations of handedness for the deltahedra here are as follows:

2 units = 1+1 = Tetrahedron 3 units = 3+0 = Triangular Bipyramid 4 units = 4+0 = Octahedron 5 units = 5+0 = Pentagonal Bipyramid 6 units = 4+2 = Snub Disphenoid 7 units = 4+3 = Triaugmented Triangular Prism 8 units = 4+4 = Gyroelongated Square Bipyramid 9 units cannot form a convex polyhedron; see the wiki page on deltahedra. 10 units = 5+5 = Icosahedron

Some tips if you want to try on your own, whether with this unit or @neutrinoprism’s unit:

2 units has only one option

3 units can also be 1+2, which might be easier to assemble. However, especially because of the patterns on this unit, 1+2 is definitely less pleasing.

4, 5, 8, and 10 units likely have other configurations, but they’re already both aesthetically pleasing and easy to assemble.

6 units can also be 3+3 or 5+1. 4+2 is the most symmetrical, but 5+1 definitely has aesthetic value.

7 units must have 2+2, and then the remaining 3 can be any handedness; the 2 that are the same form one square pyramid, the 2+2 are a belt of 8 triangles, and the last, opposite the first pyramid, can be the same or different as the first 2.

The Eight Great Units Of Microbiology!

   Recently I've found out that this year we will roll through 8 unit in my micro class. The eight units will go by in this order: 1. Introduction to microbiology, 2. Microscopes, 3. Sterilization, 4. Infection, 5. Protozoa, 6.Bacteria, 7. Viruses, 8. Fungi. I have a few expectations of these units... very long detailed expectations that i will forcefully share with you today....

   in unit one "The intro to Microbiology" one would hope that this unit would give a brief summary of what we will learn during this course. It would be a proper introduction that lives up to the excitement of class itself! OH! What a wondrous introduction it would be full of germs, illness and hopefully decaying flesh! 

   In the fantastic unit two we will begin our journey into the fantastic world of microscopes! I hope to learn about how this stunning device can create a light powered portal to the delightful world of infectious disease. I wish to learn more about how microscopes work. I really just know that its a series of lenses in a tube that can let us literally stare death in the face. I want to look at a diagram of a microscope like the one below (x) and actually know what all the parts do.

   In unit 3; "The Unit of Sterilization," we would learn about different ways to kill off innocent bacteria that lurk within our homes, hospitals, and bodies. I would like to know if there is anything better than just "killing it with fire." Of coarse this will be important through out our lives in the medical field so that we can kill any contaminants that can affect patients or lab procedures. 

   Unit 4: The Unit Of Infectious Disease i expect that we would learn about different infamous infectious diseases. I want to learn more about how they spread and reproduce. by the end of that unit i expect each and every child to learn how to genetically engineer a common E. coli cell to become a deathly antibiotic resistant bacteria with 100% kill rate that way we will win the next biological war for sure!

   In the next unit i want to go in depth as to how protist work. i want to know they can reproduce so fast and turn my pool into a green mush without over populating the water killing themselves off. i would also like to know how some use bioluminescence (such as the one below) and if so what purpose they have. it would also be nice to know how organisms started out as a protist floating in the sea somewhere. 

   After protist we will study Bacteria. Bacteria are known to be some of the oldest cells on earth but i would like to know how they got here. I believe they have the answer to how life started... which would be cool to find out! We should probably also learn to distinguish between deadly bacteria and harmless ones. We could also learn to understand the one we do live with daily inside our bodies and in the environment around us. 

   In Viruses: unit 7 edition we shall learn about the different types of viruses. (duh) I would like to learn more about how they begin to adapt over time to become infectious and spreadable. Also if viruses don't live then what is their purpose on earth. Why are they here? We still need to learn about their structure too so that we can learn how to prevent them. 

   Finally we learn about fungi. Fungi are so far my favorite unit all because of DUN DUN DUN!

ANCIENT ZOMBIE ANTS!   Meaning that so far funguses are our best bet to achieving a zombie apocalypse! Any ways besides the almighty coolness that is undead prehistoric ants fungi can also shoot spores at astonishing speeds. I want to know how they can do such amazing things. I want to learn how they evolved to become such masters of life! 

  These 8 units will be learned in a single semester and I can already tell that this class is going to be looonnnggg and stressful (crap). I don't know if I'm going to survive. oh well...
