Energy from Matter – Chemical Energy, Atomic Energy, and Annihilation

Physics, Technology
[caption id="attachment_15861" align="alignright" width="440"] An example of fission: a neutron plus U235 produces U236 which breaks down into Kr92, Ba141, and 3 neutrons.[/caption] Energy (E) is crucial for life; there is no life apart from energy. Fortunately energy derived from matter exists abundantly. It is readily obtainable. Chemical E Our bodies require small installments of energy. This leads us to the dinner table. Our body breaks down the food we eat, liberating chemical energy that keeps us functioning and warm. For instance, there is the digestion of starch into sugar and energy. Sugar is further broken down into carbon dioxide, water, and still more energy. This form of energy can also be called molecular energy, since it comes from the breaking down of molecules. This involves the breaking of chemical…

What is a Negative Number?

Maybe a negative number is simply a number headed in a different direction. After all, an imaginary number is real. Opposite charges don’t cancel. Antimatter isn’t the opposite of matter. Male and female compliment each other. Instead of three dimensions, maybe there are six dimensions. Or if you include time, maybe there are seven dimensions. Coordinate Systems If there truly is no such thing as a negative number, then both halves of the x-axis, at 180º with respect to each other are positives headed in different directions. What would stand in the way of there being an infinite number of positive directions in between what was formerly negative x and positive x, each rotated a miniscule amount? Waves Even waves that cancel one another at various points may sing a…
