Quelle est la taille de l’univers?

En tant que formes de vie transitoires, nous ne sommes simplement pas équipés pour appréhender les étendues inimaginables de l’espace qui nous entourent. C’est en grande partie à cause des limites de perception qui sont inhérentes à nos systèmes biologiques. Ce que nos sens perçoivent et enregistrent n’est rien d’autre qu’un simple fragment de toutes […]

From Singularities to Black Hole Mechanics: Hawking’s Scientific Endeavour

The most recognizable scientist of our times has, sadly, left us this week. Stephen Hawking ushered in fundamental contributions in physics and cosmology and greatly revolutionized our understanding of black holes. It is no doubt that he left a remarkable legacy of scientific inquiry and his passing is a huge loss to the scientific community […]

The Charade of Epigenetic Evolution

Epigenetic mechanisms which involve biochemical alterations to DNA structure have been documented to result in heritable changes in gene expression. Unlike mutations, however, epigenetic changes do not involve changes in the primary DNA sequence, such that a nucleotide would change into a different nucleotide. Nevertheless, the field of epigenetics has been a fertile ground for […]

Diverse Scales

A deep connection exists between the microscopic world of atoms that holds together small molecules and the features of the macroscopic world around us, typified by complex structures, the likes of which include life, stars, and galaxies. The properties of the universe at large that have allowed biological life to evolve are determined by the […]
