I must really be an April Fool because this is a big day for me.  I’ll be on NPR’s Science Friday with Ira Flatow – to talk about science and comedy with my friends Tim Lee and Norm Goldblatt.  The show streams live from 11am to 1pm Pacific/2-4pm Eastern, in addition to airing on your local public radio station.  Listen to it here.

Then later tonight I’m emceeing a great STEM education event (STEM = Science Technology Engineering Mathematics) in the planetarium at the California Academy of Sciences.  It’s called STEMPosium and it’s an evening to honor some fantastic education innovators.  This event will be live streamed from their website at 7:30pm Pacific. Check it out!

More info on Schmahl Science Workshops:

The Bay Area is home to significant innovation in science and technology.  However many local school districts have eliminated science education from their curriculum. The key is more Science, Technology, Engineering, and Math (STEM) educated graduates if we want to continue to be leaders in the global economy. By partnering with schools, institutions of higher education, science based institutions, museums, local governments, and the business community our non-profit, Schmahl Science Workshops (SSW) develops young scientists to participate in the next wave of scientific innovation. We need your help to keep Schmahl Science Workshop strong.  We invite you to join us to celebrate the accomplishments of our students and to learn more about how you can inspire the next generation of scientists.

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

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….”

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 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.”
