GEOMETRY BLOG

Cubism is considered the first vanguard, since it breaks with perspective. In cubist pictures, traditional perspective disappears. It treats the shapes of nature by means of geometric figures, fragmenting lines and surfaces. The so-called "multiple perspective" is adopted: all the parts of an object are represented in the same plane. Picasso will also be interested in avant-garde science that at the moment pays attention to non-Euclidean geometry and the fourth dimension. The impact of non-Euclidean geometries on the philosophical thought of the time will be enormous because they questioned the positivist conception of science and supported the idea of the relativity of knowledge. What arises at this time is that, from an intellectual point of view, it was possible the existence of multiple geometries in coexistence with the Euclidean. The colors at this time were not interesting because the important thing was the different points of view and the geometrization, not ...

In this post I will expose some curiosities of different areas that have in common some relationship with geometric figures: The sewer covers are circular and not square, because a square drain cover could slip through the hole and fall into the drain, when we turn it to the side. The largest geometric solid made by man is the pyramid of Cheops in Egypt and was built in the 25th century BC. It has a height of 138m and the square base has a side 230m. It covers an area of 54,000 m 2 and was made with more than two million blocks of stone, each weighing an average of 2.5 tons. Of all the plane figures with the same perimeter, the circle is the one with the largest area. At Expo 98, the Swiss flag could see a hypercube.
