Did you know? If you get #cholera, it means "you've eaten faeces" (Dr Hagan, Ghana, via @InformGhana). A lot of the sicknesses in Ghana are due to us not getting rid of our 'private' properly. The contents of 'private' include: parasites, viruses, bacteria and worm eggs - all can cause severe disease in humans.

Your camp must be holy, so that he will n...

Continued from:  Stop Playing The Game Without Knowing The Rules At first the phenomena of nature were roughly divided into classes, like heat, electricity, mechanics, magnetism, properties of substances, chemical phenomena, light or optics , x-rays, nuclear physics, gravitation, meson phenomena, etc .

We can imagine that this complicated array of moving things which constitutes “the world” is something like a great chess game being played by the gods, and we are observers of the game. We do not know what the rules of the game are; all we are allowed to do is to  watch  the playing. Of course, if we watch long enough, we may eventually catch on to a few of the rules.  The rules of the game  are what we mean by  fundamental physics . credit:  http://feynmanlectures.caltech.edu/I_02.html#Ch1-

Continued from:  Everything is made out of this. Everything The things with which we concern ourselves in science appear in (many) forms, and with a multitude of attributes. For example, if we stand on the shore and look at the sea, we see the water , the waves breaking , the foam , the sloshing motion of the water , the sound , the air , the winds and the clouds , the sun and the blue sky , and light ; there is sand and there are rocks of various hardness and permanence, color and texture. There are animals and seaweed , hunger and disease , and the observer on the beach; there may be even happiness and thought . Any other spot in nature has a similar variety of things and influences. It is always as complicated as that, no matter where it is. Curiosity demands that we ask questions, that we try to put things together and try to understand this multitude of aspects as perhaps resulting from the action of a relatively small number of elemental things and forces acting i...

Continued from:   http://tinyurl.com/pm6q2pg The atoms (of water) are  1  or  2 × 10 − 8  cm in radius. Now  10 − 8  cm is called an  angstrom  (just as another name), so we say they are 1 or 2 angstroms (Å) in radius. Another way to remember their size is this: if an apple is magnified to the size of the earth, then the atoms in the apple are approximately the size of the original apple. Now imagine this great drop of water with all of these jiggling particles stuck together and tagging along with each other. The water keeps its volume; it does not fall apart, because of the attraction of the molecules for each other. If the drop is on a slope, where it can move from one place to another, the water will flow, but it does not just disappear—things do not just fly apart—because of the molecular attraction. Now the jiggling motion is what we represent as  heat : when we increase the temperature, we increase the motion. If w...
