On Education

Image
🔊         By all means, this treatise of the highly demanding subject will not be complete, if not for anything    else, but for the reason that will include personal only suggestions, opinions and critic. ~ ~~ ~~ ~ We're what we produce , as individuals, but primarily as societies, and we produce only what we know how. Our wellbeing depends on what we have in our disposal to live a fulfilling life and it's marked irreversibly by what we don't, especially in health care. Any one who believes this as being the absolute truth, must believe in education, you can't produce in our era what makes life better without education. The personal interest of the people to educate themselves will not change, although it's obvious and will become more obvious, that from now on to participate in the economic life that leads to good life you need education above and beyond high school.  It's science and technology that set the bar high and studying and ...

Time is on the other side.

I'm sorry I have to reposted, I had to rework it for better meaning continuity and flow of speech. Time pulls life by its hand and she's gliding along, to see, to sense to enjoy, proliferates with pride, but..... it's waning too, breadth after breadth spent. Doesn't know, time doesn't tell her it's being ebb away, cheats on young life's careless richness, don't t feel time an enemy. Young minds don't know what's thirty, forty,fifty years, they go along, they have plenty to spend. As life is waning, lessens, feels lighter, and counts her breadths fewer. Humbled then, pulls her hand, but the grasp is tight, it's late. Time, is dragging her now, time and life are one, it's nature's destiny. The mountains and the seas, the sun and the stars sent time away, life didn't learn it, nor did curing wane. Nature faulted on life, created her bittersweet. Thieves, time and demising death, you're stealin...

Energy, piezoelectric materials and hydrostatic pressure.

Eee-nergyyyyyyyy Ee-nergyyyyyyyy Here we have good energy......... ` `` ``` Although piezoelectric materials are producing little energy and they're rather expensive, I wish I could put them in a tank with a screw-hole outfit, that water/air-proofs the tank 100%, and immerse it to certain depth in the sea. Depending on how little energy is required to tie in and untie the screw, to change the hydrostatic pressure in the tank, one must wonder if there will be any useful energy left from the energy produced by the piezoelectric materials. ` ` 🔵 Even if the hydrostatic pressure will not go down to zero with the screw tied in, still the pressure will fluctuate enough, with ripples of pressure to spread through the tank while the hole will be closing and opening and thus the required change in pressure will be created.

IN THE ABSENCE OF ANALYTICAL SOLUTIONS........

POINT BY POINT CREATION OF SIMULATIONS AT THE AGE OT THE REIGNING COMPUTER, ELABORATE AND LENGTHY NUMERICAL SOLUTIONS ARE POSSIBLE IF THERE ARE SOUND THEORETICALLY DERIVED EQUATIONS TO WORK WITH, AS WE HAVE FOR EXAMPLE THE NAVIER-STOKES PARTIAL DEFERENTIAL EQUATIONS IN FLUID MECHANICS, THE NUMERICAL SOLUTIONS ARE USEFULL FOR QUALITATIVE ANALYSIS OF FLOWS. IN ATOMIC THEORY AND QUANTUM MECHANICS THE DESCRIPTIONS ARE ABOUT WHAT ONE   CAN NOT   DO OR FIND, NOT WHAT   CAN   DO OR FIND.   IT'S PROHIBITED TO ASK WHERE AN ELECTRON IS OR WAS IN ATOMS AND MOLECULES YOU CAN ONLY TALK ABOUT THE PROBABILITY OF FINDING AN ELECTRON IN A CERTAIN VOLUME IN SPACE.  TO FIND WHAT IT'S  NEEDED: HOW ELEMENTS HAVE SHAPED THEIR PREFERENCES (THEIR ATOMIC STRUCTURE) TO FORM BONDS WITH SOME BUT NOT OTHER ELEMEMENTS, SCIENTISTS USE TRIAL AND ERROR METHODS. (OFF COURSE WE ARE HAPPY FOR WHAT THEY AND THE ENGINEERS HAVE CREATED AND WE ARE OBLIGED TO THEM. SCIENCE AND TECHNOLOGY H...
