ATV – Jules Verne

The book, From the Earth to the Moon written by Jules Verne, describes firing the explorers from a canon to reach the Moon. This video explores Newton’s equation for gravitational force and how these forces change over distance. Anu Ojha explains how the International Space Station is in freefall, and how this...

ATV – Johaness Kepler

This video explains the historical context of observations and the different models of the solar system, that led to Kepler’s theories of elliptical planetary orbits. Both the Copernican and Ptolemaic models required the use of epicycles to explain retrograde motion. Kepler spent six years developing his three...

ATV – Georges Lemaitres

This video explains how Lemaître theory of the Big Bang explained the measurements made from the early 20th Century until today. The presenter, Anu Ojha, explains how different elements have different spectra because of the changes in energy levels of the electrons in the atoms. Spectroscopy of many nebulae show a...

ATV – Amaldi

The physicist Edoardo Amaldi was instrumental in the development of CERN and of ESRO, which eventually became the European Space Agency. One of the European Space Agency’s Automated Transfer Vehicles (ATV) is named after him. This video focuses on the low Earth orbit radiation environment and cosmic rays. The...

ATV – Albert Einstein

With the aid of animations, in this video, Anu Ojha explains Einstein’s theory of Special and General Relativity. Special Relativity tells us that the speed of light is constant, and therefore the measurements of space and time will change from the perspective of different observers. General Relativity tell us...

Atacama Desert

Astrobiologist Dr. Lewis Dartnell talks from the Atacama Desert about a research trip to find extremophiles that might give scientists some clues as to the kind of life that may exist on the surface of Mars.  Lewis shows how quartz can act as a natural sunscreen to enable cyanobacteria to grow in the dry desert...
