Carolyn Quinn looks under the bonnet of leadership in this two-part series, from business to politics and sport. What traits do you need to become a great leader? Is leadership 'in the blood' or can you train people to develop the right skills?

Carolyn Quinn examines the psychology of leadership. Once you've secured your position as leader, how do you deal with the demands at the top? The level of media attention across all sectors, from politics to football, means that today's leaders are under more scrutiny than ever before. In the last episode, Carolyn explores the challenges of modern leadership, from stepping up to the top job, to stepping down.

Written in 1905, Freud's groundbreaking 'Three essays on the theory of sexuality' is one of the pillars on which modern psychoanalysis rests. In the first of these essays, 'Sexual Aberrations' Freud unravels the complex diversity of human desire. Lisa talks to author, Kathy Lette to find out why fetishism isn't too far from shopping and she meets writer and psychoanalyst, Adam Phillips to find out why Freud thought the sexual instinct is such an irresistible force.

The second of Freud's 'Three essays on the theory of sexuality' is his ground breaking and shocking exploration of the relationship between children and their parents. In 'Infantile Sexuality' Freud outlines why our experiences and frustrations in childhood form the basis for our adult neuroses. Lisa Appignanesi talks to psychoanalysts and writers to find out how Oedipus lives on today.

In The last of Freud's essays on sexuality he explains why the troubled adolescent has to relive childhood in a bid to leave home. Lisa talks to psychoanalysts working today to find out how the struggles of adolescence have changed over the course of hundred years. She also talks to writer, Sue Townsend to find out what inspired her to write about teenager Adrian Mole and what Freud might have made of him, now, aged 38 and 3/4.

Fragment of an Analysis of a Case of Hysteria' is Freud's first great case history. Dora was brought to Freud for analysis by her father because of hysterical symptoms and threatened suicide. Dora rejected Freud's interpretations and fled before her treatment was over. Why did she leave and what did Freud learn from his apparent failure? Lisa talks to psychoanalyst and writer, Susie Orbach to find out why 'Dora' would lead to the invention of one of psychoanalysis's most important tools.

The Joke Book. In 'Wit and its relation to the Unconscious' Freud explained why the joke, like the dream provides a unique window into the unconscious. Lisa talks to comic Arnold Brown and therapist turned comedian Inder Manocha, to find out what drives the urge to make others laugh. She also talks to psychoanalysts David Bell to find out why we laugh, why we give ourselves away by our jokes and asks if there is a place for humour on the therapist's couch.

Programme 1: 1 – the most popular number! Literally, the most popular number, as it appears more often than any other number. More specifically, the first digit of all numbers is a 1 about 30% of the time, whereas it is 9 just 4% of time. This was accidentally discovered by the engineer Frank Benford. It works for all numbers – mountain heights, river lengths, populations, etc.

Programme 2: 2 - At the double. We all remember the story of the Persian who invented chess and who asked to be paid with 1 grain of rice on the first square, 2 on the second, 4 on the third and so on, doubling all the way to the 64th square. He bankrupted the state!

Programme 3: 6 degrees of separation Six is often treated as 2x3, but has many characteristics of its own. Six is also the "pivot" of its divisors (1+2+3=6=1x2x3) and also the centre of the first five even numbers: 2, 4, 6, 8, 10. Six seems to have a pivoting action both mathematically and socially. How is it that everyone in the world can be linked through just six social ties? As Simon discovers, the concept of “six degrees of separation” emerged from a huge postal experiment conducted by the social psychologist Stanley Milgram in 1967. Milgram asked volunteers to send a package by mail to one of a hundred people chosen at random. But they could only send mail to people they knew on first name terms.

Programme 4: 6.67 x 10^-11 – the number that defines the universe. Newton’s equation of gravity included a number G, which indicates the strength of gravitation. It took 100 years before the shy Englishman Henry Cavendish (he left notes for his maids because he was too shy to talk to women) measured G to be 6.67 x 10^-11 Nm²/Kg². It allowed him to weigh the Earth itself.

Programme 5: 1729 – the first taxicab number Curious properties sometimes lurk within seemingly undistinguished numbers. 1729 sparked one of maths most famous anecdotes: a young Indian, Srinivasa Ramanujan, lay dying of TB in a London hospital. G.H. Hardy, the leading mathematician in England, visited him there. "I came over in cab number 1729," Hardy told Ramanujan. "That seems a rather dull number to me."
