Answer 1

Most of the inventions or discoveries of the great scientists in this era are based upon the facts that previous scientists had found. They are therefore indirectly credible for these discoveries. If they had'nt done their work earlier, today's discoveries would not have been possible. Hence their names are reflected. It might also be as a tribute to them.
