The next edition of the Ratio Popular Science Forum is coming up soon. We’d love to welcome you to our new science adventure on June 15!

We’ll gradually reveal the topics of this year’s spring edition, but you can expect surprises in different scientific fields.

During the past nine forums we colonized the cosmos (at least in words), we looked into the dark Universe through the eyes of Euclid, we linked maths with murder and malaria, we planned editing humans with CRISPR/Cas-9 technology, we researched the psychology of ghost sightings, we saw how neurons are connected in the brain, there were even ants and flies!

Over the past 6 years, the stage of Ratio has welcomed international speakers like Peter Watts, Christopher French, Maggie Lieu, Allain Buisson, Steven Le Comber, and many others

During the breaks in between the talks you will never be bored – past guests have had the chance to play in Martian gravity, see a mini-model of the Curiosity rover in action, watch different experiments, and even attend an impromptu stand-up comedy skit by one of our speakers. Our partners will also provide you with interesting and engaging content.

What’s going to happen on June 15? Stay tuned and make sure you’ll be there. Our early bird tickets are already on sale!

Lectures and talks

Matthew Cobb: Where are the aliens?

Matthew Cobb

"Is there life on Mars, or anywhere else in the Universe except from Earth?”

The Universe is vast, and composed of billions of galaxies, each of which contains trillions of stars and uncountable numbers of planets. It seems inevitable that there must be life elsewhere, and yet we have no evidence. The skies are not full of robot probes from other civilizations, nor have our radio telescopes detected the slightest bleep from aliens. The great physicist Fermi put it this way: “Where is everyone?” Part of the reason many people assume that there must be life elsewhere is that they do not understand quite how unlikely the origin of intelligent life on Earth has been. By exploring the only form of life we know – that found here – it begins to look as though we may be alone, in our galaxy at least.

Ceri Brenner: Extreme Lasers

The most powerful lasers in the world generate micro balls of plasma that are heated to millions of degrees in billionth of a second. They can be used to drive super-strength, micro-sized plasma accelerators that generate bright, highly-energetic beams of x-rays and particles.

The research community is now working with industry and clinicians to develop this new technology for applications such as targeted cancer therapy, and for high resolution 3D x-ray imaging of objects such carbon-fibre composite materials right up to 3D printed steel aerospace components and jet engine parts, and neutron inspection for mapping the contents of nuclear waste barrels. These super power lasers can now fire beams at 10 times a second so using these extreme lasers for societal impact and industrial solutions is just around the corner.

In this talk Dr Brenner will introduce some of the key physics behind the concept of laser-based particle acceleration in intense laser-matter interactions, and subsequent x-ray generation. Applications of this technology will also be covered, demonstrating the multi-disciplinary impact of this exciting field of research and innovation.

Sheena Cruickshank: Тhe microuniverse in your body

We are never alone with around 38 trillion bacteria co-habiting our body. These bacteria along with a whole host of other organisms make up our microbiome. Our microbiome has co-evolved with us and has many vital roles for our health. Bacteria also have an amazing ability to change and enable their host to do things they couldn’t normally do. However, changes in our microbiome are also linked to a whole host of diseases and conditions including obesity. The big question is whether we can change our microbiome to exploit its beneficial functions. Find out how our microbiome is so important for our wellbeing, the extreme measures some people are taking to manipulate it and what learning about the microbiome may help us do in the future.

Discussion: Lose your self with Tamler Sommers, Joshua Weisberg, Greg Dunn

Neuroscience and experimental psychology have only just begun to probe the depths of the human mind. While there are great difficulties correlating mind and brain, these sciences open new ways to explore foundational issues about mind and self.

Among these, we find new practices and substances that remodel our brains. Long-term meditators, for example, exhibit reduced anxiety, depression, neuroticism, and modulation of brain networks including anatomical changes. And psychedelic drugs show promise in the treatment of PTSD and depression, as well as offering insight into the nature of spirituality and the experience of transcendence.

But the more we understand about such experiences, the more pronounced the question of the self becomes. Is there really a substantial self unifying all our experiences, or are we just a loose fabric of conscious moments, a thin construction of our brains? Tamler Sommers, Josh Weisberg, and Greg Dunn will search for the answers of these questions and also questions of the nature of the self at a moment and over time, how self-awareness might differ from consciousness, what is ego dissolution, and more.
