I suppose if the general public tend to be persuaded more by style rather than substance, then this style of essay should be more attractive to them rather than just saying "basic, fundamental research is important for its own sake, because you just never know what it will spawn in the future".
That is essentially what this excerpt is saying. It is an excerpt from the book "The Education of T.C. MITS --What Modern Mathematics Means to You" written by Lillian Lieber. It is an "illustration" to justify the esoteric part physics and mathematics, and why they are worthy of support.
There are certainly many good points being made here. And maybe the style points are just exactly what the public might be attracted to to pay attention to the content.
So is it working?
