Transcript

I am in the coffee room where element 109, meitnerium was named. In here, imagine it: 20 people sitting round arguing “What are we going to call this new element?” Writing the names on the blackboard…they rubbed it off! But there, they had the whole choice of what the elements were called. Like many others of these very heavy elements, meitnerium w... Read More
