Physicists detect the undetectable: 'baby' solitary waves

When University at Buffalo theorist Surajit Sen published his prediction that solitary waves, tight bundles of energy that travel without dispersing, could break into smaller, "baby" or secondary solitary waves, experts in the field acclaimed it as a fine piece of work.
They also felt that these waves might never be seen experimentally.
But in a paper published this week in Physical Review Letters, Sen and his co-authors report that they have done just that.
