Remember the fancy Hubble Space telescope? It was launched into low Earth orbit in 1990, and its 2,4 meter mirror observes the near ultraviolet, visible and near infrared spectra.
Its orbit just outside the distortion of earth’s atmosphere, allows it to take extremely high-resolution images with negligible background light.
It has recorded some ...

There is a video trending these days which is titled “How to go to Space, in Simple Words”. They creators are trying to explain the whole concept of how a person can go to space using only the 1000 most used words in the English Language.

We all have in mind that lasers are for cutting ...

Our last two posts, were about that fascinating Google attempt to provide internet access to our planet's remote areas. Project Loon.

Oliver Queen, is a billionaire (!) who loses his father (!!) in a boat accident and he become a ...

The superformula is a generalization of the superellipse and was first proposed by Johan Gielis in 2003. Gielis suggested that the formula can be used to describe many complex shapes and curves that are found in nature.

In polar coordinates, with r the radius and φ the angle, the superformula is:

The parametric equation for X ...
