Composting and waste-to-energy are winners in a new study of food disposal options.

August 30, 2011

 

I have been having a lot of fun feeding worms my garbage. We have something you could either call a "worm bin" or a "home vermicomposting system," and we throw our food scraps, banana peels, melon rinds, moldy bread--you name it--into that. There are a couple pounds of worms in the bin, and they gratefully accept the waste, eat it,... Read more

Many professors use EBN feature articles as course material. We're always looking for ways to make their lives easier.

We are already adding blankets to our beds here in Vermont, and it's still dark when my husband and I get up for our early-morning run. Looks like time to wean the kids off their late-to-bed/late-to-rise schedule and remember... Read more

August 9, 2011

As I was hosing down the dirt driveway in front of my house last week to keep the dust down with some guests due to arrive, I got to thinking about Chicken Dinner Road.

I once lived in Canyon County, Idaho and often passed a junction for Chicken Dinner Road. Some years ago, I was told, this road was a dusty dirt track traveling... Read more

It's easy to augment your existing windows to keep the heat in better, but some "window attachments" are better than others.

August 3, 2011

 

Try this little perceptual experiment now: look at yourself in a mirror (or your computer or phone camera). Then look at your left eye, and then your right eye, and then back and forth several times. What do you see?

If someone else is around, ask them to look at you, and look back and forth between your eyes.

Should you replace your old windows? Using attachments can get more life out of them, and improve performance.

Most of us approach poorly performing old windows with a step-by-step exploration from one less-than-optimal fix to the next. Improving existing window performance shouldn't be that way, and it doesn't have to with new online... Read more

Once upon a time in a village there lived a wise old man. Legend had it that he could answer any question posed to him. A village boy hatched a plan to fool him. He caught a small bird, and approaching the wise old man with the bird in his hands, he asked, "Is this bird dead or alive?"  If the man said it was alive, the boy would... Read more

Poetry used to be memorized, not written down, and handed from bard to bard, memory to memory, down through the generations. Perhaps folks out there have memorized poems back when schools taught such things, or for personal interest.
