Polytopes in Geometry.

In elementary geometry, a polytope is a geometric object with flat sides, which exists in any general number of dimensions. A polygon is a polytope in two dimensions, a polyhedron in three dimensions, and so on in higher dimensions (such as a polychoron in four dimensions). Some theories further generalize the idea to include such objects as unbounded polytopes (apeirotopes and tessellations), and abstract polytopes. When referring to an n-dimensional generalization, the term n-polytope is used. For example, a polygon is a 2-polytope, a polyhedron is a 3-polytope, and a polychoron is a 4-polytope…See more : History and Different approaches to definition at Polytope on Wikipedia.
In  “Universal constructors in polytopal graph theory”, a article about Polytopal graph theory, the author wrote:
Polytopal graph theory is concerned with the graphs formed by the edges and vertices of polytopes. The graph of a simple polytope contains all of the necessary information to recover its full combinatorial structure in polynomial time, and thus is equivalent in a strong sense to the object. These objects are both mathematically and aesthetically beautiful as well as practically relevant.  Properties of polytopal graphs are linked with a number of important algorithmic questions about polytopes such as the complexity of  linear programming and the convergence of randomized algorithms - Source.

How Colors Smell"When someone asks me what flavor slushie I want, I don’t say “cherry,” I say “red.” That flavor is called “red.” “Blue” is another flavor a slushie might have. Similarly, a cherry smell—especially the chemically cherry smell of a red slushie—is a red smell.That one’s easy, since cherries are red. It doesn’t take a wild leap to make that association. But what color is the smell of, say, soap?A new study published in PLOS One finds that some people say white, some say yellow, some say blue. A group of international researchers had people from different cultures smell 14 scents and choose from 36 colors the one that they associated most with the odor.”

The Space-Beer Race Heats Up
“A small team of people gathered in the Nevada desert earlier this week to take another step toward answering one of mankind’s most pressing questions: What does beer taste like in space?
At least that’s one of the most pressing questions that comes up when a bunch of brewers get together with a bunch of amateur rocket builders. To find an answer,Ninkasi Brewing Company of Eugene, Oregon teamed up with the Civilian Space eXploration Team and Team Hybriddyne to launch some live yeast to space, bring it back to Earth, and then brew beer with it.”

Researchers successfully 3D print blood vessels, a ‘game changer’ for artificial organs
“Hundreds of thousands of people die annually because the demand for organs far exceeds the donor supply. Artificial organs could save those lives — and scientists just made a huge breakthrough in the field by “bio-printing” artificial vascular networks.
Researchers from the University of Sydney, MIT, Harvard, and Stanford have successfully bio-printed blood vessels, offering 3D-printed organs access to nutrients, oxygen, and waste-disposal routes, according to a study published Monday.”

PREHISTORIC SHARK: MEGALODON

Megalodon is an extinct species of shark that lived 1.5 million years ago and as you can probably tell from the above pictures it was HUGE, here are some few facts

  • It’s teeth were over 7 inches long
  • It’s bite can deliver from 10.2-18.6 tons of force, enough to crush a prehistoric whale’s skull like a grape
  • It feasted on prehistoric whales, dolphins, squids, fish, and even giant turtles 
  • It’s fossils have been found all over the world
  • No one knows why it went extinct
