Amazing Technologies, Weapons and Gadgets of the Ancient World
Explore the clever ancient technologies, cunning weapons, and curious gadgets which shaped our modern world and still reflect the brilliance of ancient minds. Incredible ancient technologies leave us awe-struck at the knowledge and wisdom held by people of our past. They were the result of incredible advances in engineering and innovation as new, powerful civilizations emerged and came to dominate the ancient world. Many ancient inventions were forgotten, lost to the pages of history… Travel with Ancient Origins now to experience the surprising and clever “Amazing Technologies of the Ancient World”. - 1 - Begin your explorations with Ancient Origins Member eBooks!

Optimal Cells in Crystallography and Arts
Journal for Geometry and Graphics Volume 24 (2020), No. 1, 103–124. Optimal Cells in Crystallography and Arts Katalin Máthé1, Jenő Szirmai2 1Institute of Applied Arts, Department of Design, Sopron University, Hungary email: [email protected] 2Dept. of Geometry, Inst. of Mathematics, Budapest Univ. of Technology and Economics Egry József u. 1. H. ép. 22, H-1521 Budapest, Hungary email: [email protected] Abstract. This is an overview on ball packings in different geometries. How- ever, parallel to reported mathematical results we discuss various appearances of related phenomena in arts and architecture. The ball (or sphere) packing problem with equal balls, without any symmetry assumption, in a 3-dimensional space of constant curvature (E3, H3, S3) is a very intensively researched area of geometry. In the Euclidean space E3 the famous Kepler conjecture was settled by Thomas Hales and in other spaces of constant curvatures (H3, S3) was partially solved by Böröczky and Florian. However, in the hyperbolic space H3 many open questions still need to be answered. In each considered geometry to every optimal ball packing configuration belongs a tiling, e.g., Dirichlet-Voronoi tiling. Their tile types play important roles in the crystallography. Throughout human history the phenomenon of space and its orderliness has been intriguing artists as well, who, at many instances has intuited spatial configu- rations that bear striking resemblances with the outcomes of scientific research done in this field. In an attempt to blur a rather artificial boundary between the sciences and the arts, the ball packing problems unfolded in this article will be illustrated not only with mathematical visuals but with relatable artefacts and short introductions to their contexts. -

1 Rediscovering Our Purpose. Who Are We? by Edgar Solís August 15
1 Rediscovering Our Purpose. Who are we? By Edgar Solís August 15, 2021 Introduction. If we want to know the purpose of something, we need to know its origin; who created it and why? I want to show you four different things. I invite you to guess. What is this, and what is its purpose? #1 Roman Dodecahedron. This thing was discovered in 1739. Since then, at least 116 similar objects have been found from Wales to Hungary and Spain and to the east of Italy, with most found in Germany and France. Experts have called them "Dodecahedrons." Ranging from 4 to 11 centimeters (1.6 to 4.3 in) in size. These Dodecahedrons have been found in contemporary accounts or pictures of the time. One speculated use is a candlestick holder (wax was found inside two examples) but this isn’t for sure. Experts cannot find the purpose of these artifacts. Smaller dodecahedra with the same features (holes and knobs) and made from gold have been found in Southeast Asia along the Maritime Silk Road. They have been used for decorative purposes, and the earliest items appear to be from the Roman epoch. What is this? #2. Old Computer. #3. Ancient copper coffee machine. #4. Blue Dragon. "Glaucus Atlanticus" 2 Just like trying to discover the identity and function of these items, since the beginning of human existence, people have tried to answer these questions: Who are we and what is the purpose of our existence? If we have an explanation of why we exist, then we can find purpose to our life, but if we don't know from where we came or why we are here, then human life and the existence of all creation is pointless.
