Why was spencer silver's work an essential part of
fry's invention?

fry remembered a curious adhesive - a strong and yet
easily removed "unglue"- that spencer silver, another
3m researcher, had come upon several years earlier.
silver felt the unusual adhesive might have some
commercial value, and so he demonstrated it to various
colleagues, including fry. at the time, no one had come
up with a use for it, and so the formula for the weak
adhesive was filed away - until the monday morning
when fry came to work with the idea of making sticky
bookmarks that could also be removed without damaging
the book.

" "it isn’t that," said scrooge, heated by the remark, and speaking unconsciously like his former, not his latter, self. "it isn't that, spirit. he has the power to render us happy or unhappy; to make our service light or burdensome; a pleasure or a toil. say that his power lies in words and looks; in things so slight and insignificant that it is impossible to add and count ’em up: what then? the happiness he gives, is quite as great as if it cost a fortune." he felt the spirit's glance, and stopped. "what is the matter? " asked the ghost. "nothing particular," said scrooge. "something, i think? " the ghost insisted. "no," said scrooge, "no. i should like to be able to say a word or two to my clerk just now. that's all."
