Dazzling, science? Not always. If it can be slow, laborious and repetitive, it is often at this price that it provides answers. Some experiences can even last for decades. Stories of some of these challenges to time.
How to pass on to future generations the memory of radioactive waste storage sites, intended to keep them underground for millennia? A headache for all projects of this type in the world.
