Unusual 3D printers: The human body organs, clothes, and even cookies are made!

The 3D printer is a device that makes things easy to fabricate three-dimensional objects. The typical materials to be used with the printer are synthetic resin (plastic) or metal powders. However, there are also biological cells, textile fibers, and wheat flour as the materials for 3D printers. A printer using biological cells can make aRead more about Unusual 3D printers: The human body organs, clothes, and even cookies are made![…]

Discrete dynamics and its applications to our daily lives

Discrete dynamics and its applications to our daily lives

Math, physics, engineering, and our lives are closely related. Physics formulates the nature’s motion with mathematics. This provides applications to creating a convenient system for our living. Let us introduce a two dimensional discrete mapping: x_(n+1) = 0.6x + y + 5.2/(1.0 + x^2) y_(n+1) = -0.9999x The plot is shown as a picture above.Read more about Discrete dynamics and its applications to our daily lives[…]

Georg Simon Ohm’s biography: How Ohm’s law was formulated

Georg Simon Ohm’s biography: How Ohm’s law was formulated

Georg Simon Ohm (1789 – 1854) He was born in Bayern State in Germany. His father studied math, physics, and philosophy by himself and taught his children what he learned. Because he learned enough from his father, Georg thought that he wouldn’t learn anything in school when he was eleven years old. After completing theRead more about Georg Simon Ohm’s biography: How Ohm’s law was formulated[…]

Manufacturing and engineering owe electricity and magnetism

Manufacturing and engineering owe electricity and magnetism

Michael Faraday was a British physicist who contributed to many of important findings for electromagnetic phenomena. His family was challenged economically, but his siblings and religious belief supported him. In his childhood, he was interested in doing experiments by reading science books. The turning point of his life came when he audited Humphry Davy’s science lecture.Read more about Manufacturing and engineering owe electricity and magnetism[…]
