piezoelectricity? … what is that? … too many syllables!

no, wait! read on!! … physics is really cool! …atom

understanding the physics of our world and of our surrounding galaxy and Universe is an intensely fascinating venture! … the principles of physics, chemistry, math, and biology that govern and effect our existence are literally incredible …

it’s exciting to see how persistent humans are in exploring realms of the unknown … we really are innately curious creatures, and that makes life a lot of fun! … for millenia humans have probed and prodded physical and metaphysical realms to search for the answers to their incessant, insatiable questions … this is a good thing because we’ve learned so much … the power of our knowledge, however, must be respected deeply because knowledge can be used destructively or constructively …

in the mid- to late-19th century, several scientists discovered some materials generate an electrical potential when they are mechanically stressed (e.g., squeezed, compressed, etc.) … dubbed piezomorphic (a word derived from Greek: piezo = squeeze or press + morh = form) substances, people soon realized that there was a great potential (no pun intended!) for using these materials to generate different forms of energymore…

as litter, plastic bags are especially harmful for wildlife, which may become caught and entangled in whole or torn bags … some animals may also accidentally ingest and suffocate on bags that are mistakenly taken for prey … plastic bags also choke plants, shading them from essential sunlight and sealing them off from the carbon dioxide they respire … keep in mind that plants (and the microorganisms upon which they are dependent) are the vital foundation of almost all ecosystems … more…
