I visited the Hiroshima museum last year. They've got a set of stone steps, a person was sat there when the bomb went off and they were simply vaporised. The stone steps bear the residue of the person, almost like a shadow.
As a teenager we also visited concentration camps on a school trip, and a survivor joined the trip from Norway to Germany. We got to know him a bit during the week long trip, and there was a session where he told his story. I'll never forget this, and I think it affects me to this day.
Soon we will have no Time Witnesses left.
Edit: I remembered a very specific anecdote he told, about how him randomly having learned to knit helped when in a concentration camp, as some officer wanted something to be made, and he then could sit inside and do that instead of working himself to death in the quarry. Based on this I managed to find his name again now.
Haakon Sørbye, thanks for telling us your story.
You can't turn material into "nothing". At best you can turn it into equivalent amount of energy if you collide it with antimatter.
That being said I don't really feel the difference between "vaporisation" and "disintegration". In both cases you stop being biology and start being physics in a subjective instant. (at least from the perspective of your own central nervous system, which has not enough time to even detect that something has happened)
In both cases you go from a living, breathing, laughing, thinking human being into contaminants in the air or surfaces around you.
What do you feel is the difference between "vaporisation" and "disintegration"? Is it about how big your largest continuous chunk is? Where do you draw the line?
It could be (and I think it's more likely) that the rest of the stone was lightened, and the part in the shadow, wasn't.
No "residue of a person", just literally "shadow".

The immense heat and light from the detonation burned/discolored the stones, but not in the shadow of the person sitting on the steps. Hence why you can see these 'permanent shadows' in various places in the city. Some caused by humans, but most are just shadows of structures.
