High serotonin/low octopamine characterizes the victor. The opposite neurochemical configuration, a high ratio of octopamine to serotonin, produces a defeated-looking, scrunched-up, inhibited, drooping, skulking sort of lobster, very likely to hang around street corners, and to vanish at the first hint of trouble.
A weaker lobster will quit trying, accept his lowly status, and keep his legs attached to his body. The top lobster, by contrast—occupying the best shelter, getting some good rest, finishing a good meal—parades his dominance around his territory, rousting subordinate lobsters from their shelters at night.
Eco-activists, even more idealistic in their viewpoint, envision nature as harmoniously balanced and perfect, absent the disruptions and depredations of mankind. Unfortunately, “the environment” is also elephantiasis and guinea worms (don’t ask), anopheles mosquitoes and malaria, AIDS, Black Plague.
Unfortunately, that physical hyper-response, that constant alertness, burns up a lot of precious energy and physical resources. This response is really what everyone calls stress, and it is by no means only or even primarily psychological. It’s a reflection of the genuine constraints of unfortunate circumstances.
To stand up straight with your shoulders back means building the ark that protects the world from the flood, guiding your people through the desert after they have escaped tyranny, making your way away from comfortable home and country, and speaking the prophetic word to those who ignore the widows and children.
Components of a vector can be accessed via vec.xwhere x is the first component of the vector. You can use .x, .y, .z and .w to access their first, second, third and fourth component respectively. GLSL also allows you to use rgba for colors or stpq for texture coordinates, accessing the same components.
More generally, a textbook or a course must lead students through a series of subsets. We consider it our responsibility to select topics and to provide emphasis. We can’t just present everything, so we must choose; what we leave out is at least as important as what we leave in — at each stage of the journey
The most basic building block of programs is an expression. An expression computes a value from a number of operands. The simplest expression is simply a literal value, such as 10, 'a', 3.14, or "Norah". Names of variables are also expressions. A variable represents the object of which it is the name.
Note that a<b<c means (a<b)<c and that a<b evaluates to a Boolean value: true or false. So, a<b<c will be equivalent to either true<c or false<c. In particular, a<b<c does not mean “Is b between a and c?” as many have naively (and not unreasonably) assumed. Thus, a<b<c is basically a useless expression.
