It seems a fairly obvious question when you see things happen, to wonder how they happen.  How can it be?  You see, in the 1800s they could see that frog spawn, these eggs turned into tadpoles, and even then they’d say, “Well, how can that be?”  So the idea at that time was probably the same as many people have now. If I stop someone in the street and said, “Excuse me.  Tell me, how does this frog spawn turn into a tadpole?”  What sort of answer do you think you’d get?

They might say, “Well, perhaps there’s a miniature tadpole inside the egg.”  That’s the best idea. And that you can’t see it because it’s so small.  It just grows bigger and bigger until this little miniature tadpole frog can be seen.  That was a plausible idea. Otherwise, you’re right.  I mean, how can it possibly happen?  And when you look inside a frog egg, which you can do now microscopically, there is no tadpole there.  No frog at all.  I’s just like soup.  But somehow it knows how to turn itself into what we see.  So there are very good questions I think. And if a younger person — my advice always to younger people is find something you’re interested in and pursue it.  It doesn’t matter what it is.  Don’t be pushed into some direction that you think is just boring and useless.

Many people who are very successful in their careers, it turned out that they were very interested and keen on whatever it was at an early age.  We hear of famous sportsmen who start playing a sport at age two or three and that’s what they really like.  So parents wisely say, “Well all right. I’ll give you a tennis racket or something and you can just try your hand at that.”  So I think the advice is — to younger people — encourage them to find anything they think is interesting and pursue it.
