Who knows the reasons for having a question that will guide his life's work. Maybe, when pondering life's great mysteries, he prefers the guidance of physics to that of religion. Maybe he has always dreamed of circling the Earth in the International Space Station, watching every 90 minutes over the soapy blue of his home planet. Maybe he accidentally put a fork in a microwave one hour.

The young Slepkov had discovered the old grape-in-microwave trick, in which a sliced ​​grape erupts into a fireball of plasma, and ionized gas that is considered the fourth state of matter and is present in large quantities, among other places, the sun. Twenty years later, Slepkov, now a physics professor, took his own experiment to explain how the phenomenon worked.

"The more or less consensus explanation was that the grape would work as an antenna. and that would create a current through the skin bridge that would eventually heat it up and create the plasma, ”says Bianucci.
