Gregory Benford Quotation on Passion

“Pas­sion is inversely pro­por­tional to the amount of real infor­ma­tion available.”

- Gre­gory Ben­ford’s law of con­tro­versy (an adage from his 1980 novel Timescape).

Stand up straight!

My mother used to tell me to “stand up straight.”

It was one of her favorite things to say: “Stand up straight!”

Many other peo­ple, I have dis­cov­ered, also grew up hear­ing that phrase. It’s nearly uni­ver­sal. As if moth­ers were pro­grammed to say it. In fact, I believe moth­ers have been telling their chil­dren to “stand up straight” longer than we real­ize. Per­haps even to pre-human days.

What if that were the dri­ving force behind the evo­lu­tion­ary trend to walk erect?

Moth­ers nag­ging their chil­dren up the evo­lu­tion­ary ladder:

“Stand up straight!
“Don’t drag your knuck­les when you walk!
“What’re ya born in a tree?
“You want the other fam­i­lies to think we’re not evolving?”

“No, mom…”

Then: “How many times do I have to tell you?”

And, therein lies the ori­gin of mathematics:

“How many times?…well, if I put the three here and carry the one….”

Conservation of Mass

I noticed a long time ago, when­ever my mother would lose weight, my father would gain weight. And when my father lost weight, my mother gained weight.

It was like the Con­ser­va­tion of Mass, within our family.

Being the young sci­en­tist that I was, I devel­oped a the­ory to explain the facts: You see, you never actu­ally lose weight….you just give it to some­body else.

Fat can be nei­ther cre­ated nor destroyed. It’s one of the basic laws of the uni­verse. You need to know the laws if you’re gonna live here.

The Batting Average Paradox

In the nor­mal course of my web brows­ing, I stum­bled upon the home page of Stephen E. Schwartz, an atmos­pheric sci­en­tist at Brookhaven National Lab­o­ra­tory and chief sci­en­tist of the Depart­ment of Energy’s Atmos­pheric Sci­ence Pro­gram.

The page gets pretty tech­ni­cal for those of us who are not atmos­pheric sci­en­tists, but near the bot­tom of the page he men­tions “the bat­ting aver­age para­dox” – which con­tains a sur­pris­ing bit of math that any of us can appreciate…

The bat­ting aver­age para­dox. Able has a higher bat­ting aver­age than Baker in the first half of the sea­son and also in the sec­ond half. You might think that that means that Able has a higher aver­age for the sea­son. But you would be wrong. Click here to see why aver­ag­ing ratios can be mis­lead­ing.”
