In part two, Professor Al-Khalili looks at the 19th century chemists who struggled to impose an order on the apparently random world of the elements. From working out how many there were to discovering their unique relationships with each other, the early scientists' bid to decode the hidden order of the elements was driven by false starts and bitter disputes. But ultimately the quest would lead to one of chemistry's most beautiful intellectual creations - the periodic table.
Drinking alcohol on a cold day warms you up. Eating grilled meat can increase your risk of cancer. Mosquitoes prefer blondes… ah, women. We've all heard the claims, but are they true? From Winnipeg to Florida, from New York City to Vancouver, B.C, molecular biologist Dr. Jennifer Gardy goes in search of the answers. It's a journey through seldom-seen research that forces Dr. Gardy to become a real-life guinea pig to test these claims and discover, once and for all, whether they're science fact or science fiction. The surprising results are revealed in Myth or Science. , results that could change your life. Most of us just accept these myths as fact. But it is surprising to discover which are true and which aren't. It's not what you expect. And the answers can make a major difference to your daily life, and your health.
In a powerful conclusion, Brian pieces together this story of creation that started with what Einstein called the 'happiest thought of his life' - the moment that he realised that gravity was far stranger than anyone had imagined. In an incredible experiment inside the largest vacuum chamber, Brian reveals how Einstein formulated a new theory of gravity, which ultimately took us back to the big bang. And how in doing so, we humans found our true place in space and time.
