They are everywhere, mostly invisible, and they keep our world running - bacteria, viruses, algae and fungi.
Miracle bacteria, star snot, meteorite eaters: the earth is actually a planet of microorganisms and if we want to understand what kind of world we live in, we have to make the invisible visible.
How did an inconspicuous bacterium bring Corpus Christi to Christianity? Why is an eye animal the beacon of hope for space travel and why might we have to let spaceships go mouldy in the future?
What do microbes have to do with our winter holidays and why do they want to get their hands on the banana?
Without microorganisms, our world would be completely different from what it is. The invisible creatures are much more than the pathogens we think of them as. They have influenced our art and culture, our politics, food and everyday life.
They live around us and within us and have literally reshaped the world we live in.
"Microorganisms are important - and they taste good (as long as you eat the right ones)," Freistetter says. At Geist Heidelberg, he explains the cosmos of microbiology in an informative as well as entertaining way, showing us a history of the world as it has never been seen before.
