Little Changes = Big Results For The Earth

According to GreenWaste, the average person generates 4.5 pounds of trash per day – that's 1.5 tons per year per person. The really baffling part of that number to me is that approximately 45% of our waste generated per year could have been recycled! I know personally that the initial thought of adding extra work to my everyday life seemed daunting, but the fact is, taking an extra minute to change my original course of action makes a huge impact for us all.

I'm lucky enough to work in a place where Green Mission is ingrained in our everyday actions so carrying over good habits hasn't been all that challenging thanks to the lessons I've learned at Whole Foods Market after I decided a good starting point for myself. Below are a few of the tricks I've adopted at home and links to resources that helped me to change my behavior.

For Carl: Three New Worlds in the Cosmos

It seems like just yesterday. In 1980, astronomer Carl Sagan presented Cosmos, his PBS series about the joy and beauty of scientific discovery. More than anything else (yes, I have to admit, even more than my childhood visits to COSI), Cosmos awakened in me a love and a passion for science that has never dimmed.

In one of my favorite scenes, Sagan visits his old sixth grade classroom in the Bensonhurst section of Brooklyn. Sagan talks to the students there (who, coincidentally, were just my age at the time) about what a special time this was, the first time that humans had begun to explore the universe. In particular, Sagan talks about the beginning of our search for planets beyond the solar system.

The Electroscope, Dark Matter, and Mystery

We have a new toy in the Electric Workshop at COSI. It's called an electroscope.

On the 1898 side of Progress, you might happen upon our Electric Workshop Show (check your daily schedule for show times). The Electric Workshop is one of COSI's hidden gems, a live demonstration all about the history (and future) of electricity. You can become an electric generator, make real lightning with our Wimshurst machine, and discover the mysterious power of a new kind of energy called radio waves.

Now we've added an antique electroscope to help reveal one of science's great discoveries: the entire universe is electrical. With the electroscope we discover the effect of separating electric charge.

But there's a further story to be told. The electroscope lies at the heart of another mystery of science – one that, believe it or not, we still haven't solved even in 2013.

Flight: Blogging from 38,000ft

Since my daughter was born nearly three years ago, I haven't traveled much. So it was with a lot of excitement that I boarded a flight this morning to attend a conference in Portland, OR.

Ever since I was a kid (remember when you still got little plastic wings instead of a full body scan?) I have loved flying. At 14 I was lucky enough to take some flying lessons and I've never fallen out of love with the science of flight, nor have I lost my appreciation for the physics of it.

Lift. Thrust. Weight. Drag.
It seems so simple... just four small words. But, the mechanics of flight are nothing short of amazing.

Right now, I'm inside an aluminum frame that is capable of lifting and holding 154,500 pounds of weight in to the air while cruising at 593mph thanks to two massive high-pressure turbofans producing 49,200lbs of forward thrust.

Meet COSI’s newest basketball stars!

It's been an exciting Spring in the locker room at COSI, as we've watched our newest pair of rats fly through their basketball training. Penny and Bernadette played their first game for a crowd of screaming fans last week, breaking some pretty impressive training records. What makes this pair so exceptional? Our average training time is about 5-6 months, from the first day in the training court to the first public show. It can take up to 8 months for a rat to master her basketball skills, and some rats have breezed through training in about 4 months. Penny and Bernadette spent just three and a half months perfecting their skills, our current record for the fastest learners!
