SERIES INFO
Genre : Documentary
Stars : -
Series Plot : In this major new landmark series for BBC Four co-produced by PBS, Jim Al-Khalili explores the extraordinary story of six remarkable inventions: The Aeroplane, The Car, The Rocket, The Smartphone, The Telescope, The Robot. They are familiar, yet hidden within them are thousands of years of thought, struggle, sacrifice, determination and insight. The series is littered with visionaries. We peer into their original notebooks and sketches, use state of the art experiments, ground breaking drama and CGI to shed new light on the discoveries of well-known icons, like Galilei Galileo and Leonardo Da Vinci- lesser known individuals like female pioneers, Ada Lovelace and Bertha Benz- many, like the medieval scholar, Ibn al-Haytham, most viewers will have never heard of. Each episode explores little-known stories and is packed with incredible ideas: Like the beginnings of robotics 2,000 years ago or the Hollywood starlet and inventor who, while trying to defeat the Nazis, made today’s mobile network possible. We see time and again where a completely chance discovery leads to an application that no-one was expecting. The result is a mind-blowing science-led journey through human history, full of unintended consequences and incredible connections. It reveals how science, invention and technology build on one another to change everything. Mostly, it celebrates the achievements of the some of the greatest minds in human history.

EPISODE INFO
Title : The Telescope
Airdate : 2019-08-20
Episode plot : 'The telescope gave us what might be the greatest discovery of all – the universe itself.' - Jim Al-Khalili Jim Al-Khalili and a team of experts explore the fascinating story of one of our greatest inventions, the telescope, using original notebooks, stylish visualisations and sophisticated computer graphics. It is a tale full of twists and turns, involving a seashore plant, a New York property boom and a spilt bottle of mercury. Thanks to these events, the telescope allowed us to discover not just our place in the cosmos, but our origins too. Jim travels to eighth-century Baghdad to witness the first experiments in optics. Many regard this as the birth of science itself, culminating in Ibn al-Haytham’s extraordinary book explaining how light can be manipulated. In 12th-century Venice, a secret process using a seashore plant allows the manufacture of clear glass and with that, the first precision lenses. 250 years later a Dutch optician makes a chance observation: a particular arrangement of lenses magnifies distant objects. Months later, an Italian mathematics teacher, Galileo, constructs his own version and points it into the night sky. It is a revolution not just in astronomy but also in humanity’s perception of itself. In Paris, an accident with mercury allows Louis Daguerre to make highly sensitive photographic plates. Now cameras are attached to telescopes allowing celestial images to be analysed with mathematical precision. Later, a New York property boom allows a wealthy donor to fund a full-sky survey. Working on this project, Henrietta Leavitt notices that some stars undergo regular changes in brightness, which allows astronomers to measure their distance from the Earth. Edwin Hubble, using Leavitt’s discovery, measures the vast distances of entire galaxies. Hubble also discovers that the universe is expanding, implying that before the Big Bang, it must all have been in the same place. With the Hubble Space Telescope, we have reached the limits of our vision, but a new generation of telescope is about to be launched. The James Webb Space Telescope will see as far as it is possible to see, revealing new features of the vast universe we call ‘home’.
