From simple alphabets to secret symbolic languages, graphic designer Saki Mafundikwa celebrates the many forms of written communication across the continent of Africa. He highlights the history and legacy that are embodied in written words and symbols, and urges African designers to draw on these graphic forms for fresh inspiration. It's summed up in his favorite Ghanaian glyph, Sankofa, which means "return and get it" -- or "learn from the past."

What if your brain at 77 were as plastic as it was at 7? What if you could learn Mandarin with the ease of a toddler or play Rachmaninoff without breaking a sweat? A growing understanding of neuroplasticity suggests these fantasies could one day become reality. Neuroplasticity may also be the key to solving diseases like Alzheimer’s, depression, and autism. In this program, leading neuroscientists discuss their most recent findings and both the tantalizing possibilities and pitfalls for our future cognitive selves.

PARTICIPANTS: Alvaro Pascual-Leone, Nim Tottenham, Carla Shatz

MODERATOR: Guy McKhann

In the framework of the largest string theory conference in the world, Strings 2019, Science and Cocktails organized a special event at Flagey in Brussels. We were sipping cocktails in the art-deco building with string theorist and science superstar Robbert Dijkgraaf as he told us all about the fundamental laws of Nature. Afterwards, cellist and composer Benjamin Glorieux performed a musical piece together with invited guests especially commissioned for the occasion, while live-video artist Klaas Verpoest accompanied them with his visual magic.

What is string theory? What happens to stuff that falls inside a black hole? What are the fundamental building blocks of space and time? Did Nature have any choice in picking the fundamental laws of physics? What is the role of mathematics in physics?

This talk by professor Robbert Dijkgraaf was recorded on 13 July 2019 at Flagey in Brussels. For more science lectures with dry ice cocktails and live music, visit:
