you could have used instead:

(defun my-command ()
   (interactive)
   (ucs-insert "61"))

(global-set-key "b" 'my-command)

Interactive means that the function my-command is actually a command,
that is something called interactively using  M-x my-command.
Now you will probably never use that command directly, so there is no
need to give it a name.

Hence the lambda which defines an anonymous function, that is a function
without a name, and the interactive which convert it to a command.
It's a bit paradoxical, but global-set-key wants a command, not
a function, as its argument.

with current buffer being .emacs, do
M-x eval-buffer
