On November 5 we’re organizing the next edition of Ratio Popular Science Forum. We’ll talk about real things that we don’t see, unreal things we believe we’ve seen – and everything in between! We’ve chosen speakers who will considerably improve your brain’s contents.

Tickets for Ratio are already up for sale and here’s more info on our talks and speakers.



At Ratio 2017 you’ll meet three speakers that will cover diverse topics, as well as a discussion panel with completely new faces. Here are our first guests:

speakers steven goldfarbDr. Steven Goldfarb

Dr. Steven Goldfarb is a particle physicist working on the ATLAS Experiment at CERN, the European Laboratory for Particle Physics. He worked on the L3 experiment at CERN’s Large Electron Positron collider, helping to determine that there are three families of particles in the universe.

Most recently, Dr. Goldfarb has focused effort on the challenges of large-scale science communication, serving as ATLAS Outreach and Education Coordinator, overseeing worldwide communication of the Higgs boson discovery in 2012, and launching the award-winning ATLAS Virtual Visit system. He’s seen on stage both as a speaker at different TEDx events and as the frontman of the popular Geneva-based Canettes Blues Band.

The Missing Pieces: LHC and our dark Universe

Ever since ancient times, people have been fascinated by scientific discovery. Today, for the first time ever, we can discover and analyze phenomena that we can neither see nor feel directly. We will talk about dark matter, antimatter, and dark energy. We will go into extra dimensions and we will look into those 95% of the Universe that we still know nothing about.

The talk will be held in English with no translation in Bulgarian.

speakers chris frenchProf. Christopher French

Prof. Christopher French is a British psychologist and skeptic, specializing in paranormal psychology and anomalistic experiences. He’s the head of the Anomalistic Psychology Research Unit in the Psychology Department of Goldsmiths, University of London.

In addition to his academic work, prof. French participates in conferences, discussions and other public events, he’s a columnist for The Guardian and was the editor-in-chief of The Skeptic magazine for more than a decade.

The Psychology of Ghosts and Hauntings

Opinion polls repeatedly show relatively high levels of belief in ghosts even in modern Western societies. Furthermore, a sizeable minority of the population claim to have personally encountered a ghost. This talk will consider a number of factors that may lead people to claim that they have experienced a ghost even though they may not in fact have done so. Topics covered will include hoaxes, sincere misinterpretation of natural phenomena, hallucinatory experiences and pareidolia (seeing things that are not there), inattentional blindness (not seeing things that are there), the fallibility of eyewitness testimony, the possible role of complex electromagnetic fields and infrasound, photographic evidence, electronic voice phenomenon (EVP), and the role of the media.

The talk will be held in English with no translation in Bulgarian.



The autumn edition of Ratio 2017 is happening on November 5 from 10:00 to 16:00. The full schedule will be announced soon.
