Notice:
This was my first experiment on creating a discipline for the web. I
hope the mix of English and Portuguese in the first part of it will be
minimally understandable for you...
Notice-2: these lectures have started to be created in March 2012, under the intense spray of geo-engineering
in our skies, an activitywhich
affects the health of a large number of people, and was also affecting
my health. One of the main scientists of geoengineering expects
1.000.000 lives/year eliminated by such practise. Here.
Lecture
001 - (p1): Measuring,
units and systems of measure.
|
Short breath,
running nose, heavy sensation of dizziness, as being constantly infected by a
virus, coldness, lack of concentration, mind blocked, were some of the
symptoms affecting us.
Our
hospitals have registered an exceptional rise in the thousands in the
number of people dying during March 2012. Less resistant people of
course cannot survive to such conditions of aggression. You may read
more about the
spray of our skies in these articles: article; article; article
Lecture 001 - (p2):
Measuring, units and systems of measure.
|
I insist it
is time to rise the question on how such an activity is silently taking the life of thousands of persons worldwide.
Many people talk and complain about this. Mainstream news, however, don't.
Beck wrote this music
about it.
Hope you enjoy learning the basics of Physics, anyhow.
Thank you.
