I Have Spread My Dreams Under Your Feet

Aedh Wishes For The Cloths Of Heaven


W.B. Yeats

HAD I the heavens’ embroidered cloths,  
Enwrought with golden and silver light,  
The blue and the dim and the dark cloths  
Of night and light and the half light,  
I would spread the cloths under your feet:
But I, being poor, have only my dreams;  
I have spread my dreams under your feet;  
Tread softly because you tread on my dreams.

Cow Belch

Have you ever wondered what happens to the hundreds of gallons of methane gas produced each day by cows and other grazing animals? You'd think there would be herds of farm-youth with lighters standing-by to activate enormous pyrotechnics at the cows' expense, right?

Thanks to yet another hilariously educational book by Mary Roach, I've learned the cows don't belch (or fart for that matter). They actually reroute their internal tubing to move the very flammable gas from their rumens to their lungs where it is mixed in with air to be diluted to nonflammable levels, and then they "quietly" breathe it out. That is especially important since the sound that amount of gas released in any other "pressurized" way would've been an open invitation to their predators giving away their exact location.

Microbot Swarms

Inspired by colonies of worker ants, SRI International built magnetically actuated micro-robots to work in parallel in micro-factories to build electronic circuit board. The robots are built from low cost materials and their ability to work together reduces time and cost of the products they build.
