Lucie's book "15 Million Degrees: A Journey to the Centre of the Sun" is available to buy now - https://geni.us/2oB8V

110 times wider than Earth; 15 million degrees at its core; an atmosphere so huge that Earth is actually within it: come and meet the star of our solar system.

Light takes eight minutes to reach Earth from the surface of the Sun. But its journey within the Sun takes hundreds of thousands of years. What is going on in there? What are light and heat? How does the Sun produce them and how on earth did scientists discover this? Since the Royal Institution was founded in 1799 our knowledge of the Sun has changed dramatically and much of the work was carried out at the Ri.

Join Lucie Green for an enlightening talk, taking you from inside the Sun to its surface and to Earth, to discover how the Sun works, how a solar storm can threaten the modern technology that society relies on and more of the latest research in solar physics.

Lucie Green is a Professor of Physics based at the Mullard Space Science Laboratory, UCL’s Department of Space and Climate Physics. She studies activity in the atmosphere of our nearest star, the Sun. In particular, she looks at immense magnetic fields in the Sun’s atmosphere which sporadically erupt into the Solar System.

Lucie is very active in public engagement with science, regularly giving public talks and appearing on TV shows like Sky at Night.

The rich in Germany been never been as well-off as they are today and assets have never been so unevenly distributed. But who are they? How do they live? And what do they think of their country? A journey into the discreet world of the super-rich.

One percent of Germans own over a quarter of the country's assets, whilst half of the country’s citizens have no assets at all. But while the German media report on the growing poverty in the country on a daily basis, little is known about the super-rich. They keep a very low profile and can walk the streets unrecognized. "Manager Magazin” says there were around 200 billionaires living in Germany in 2018, and their numbers are increasing. The documentary "Top of the World" asks why rich Germans are so unwilling to talk about their wealth. Its author immerses himself in the discreet world of big money and meets financial advisors with 800 years of family tradition behind them and billionaires such as drugstore king Dirk Rossmann and mail-order company heir Michael Otto - as well as a self-made businessmen such as Rainer Schaller. They talk about their notions of money and justice, the origins of their wealth and their fear of social envy.

Imagine transforming barren and empty landscapes into abundant food forests, layered with mangoes, legumes, garlic, herbs and corn.

SwaYYam in South India is doing just this by using agroforestry and alley cropping to revitalise soils, produce an abundance of crops and educate local farmers.

Agroforestry and alley cropping allow multiple crops to be stacked in one space, with tree crops providing shelter for low-lying plants and holding water in the soil with their roots. Fast growing biomass plants are used as groundcover and then as a mulch to feed the soil. Nitrogen-fixers make nitrogen available in the soil for other plants and a range of crops are grown for year-round food.

Swales and ploughing on the contour work with the land's orientation to maximise water capture. Deep irrigation and pitcher irrigation take water deep to the roots of trees, especially young sapling plantings.

SwaYYAm and their educational centre, Open Shell Farm, enables local farmers to learn regenerative farming methods, helping them create their own sustainable incomes through healthy soils and bountiful harvests.

SwaYYAm is a recipient of the 2020 Permaculture Magazine Prize: https://www.permaculture.co.uk..../articles/2020-perma
