If to-day you ask a physicist what he has finally made out the æther or the electron to be, the answer will not be a description in terms of billiard balls or fly-wheels or anything concrete; he will point instead to a number of symbols and a set of mathematical equations which they satisfy. What do the symbols stand for? The mysterious reply is given that physics is indifferent to that; it has no means of probing beneath the symbolism. To understand the phenomena of the physical world it is necessary to know the equations which the symbols obey but not the nature of that which is being symbolised. ... this newer outlook has modified the challenge from the material to the spiritual world.

The attitude of Aristotelian physics toward lawfulness takes a new direction. So long as lawfulness remained limited to such processes as occurred repeatedly in the same way, it is evident, not only that the young physics still lacked the courage to extend the principle to all physical phenomena, but also that the concept of lawfulness still had a fundamentally historic, a temporally particular, significance. Stress was laid not upon the "general validity” which modem physics understands by lawfulness, but upon the events in the historically given world which displayed the required stability. The highest degree of lawfulness, beyond mere frequency, was characterized by the idea of the always eternal.

In our theory we have multiple "mini bangs” and these mini bangs are not mysterious like the big bang but they come because of the concentration of what we call negative energy fields. Whenever there are pockets of negative energy, they explode and produce a mini bang. We believe there's a mini bang producing energy in the centre of quasars, which are very bright star like objects. Gamma ray bursts, which are the explosive creations of gamma rays, are another example of a mini bang. These are actually happening. These can be described by normal physics, but the big bang cannot. The big bang theory does not use any mathematical formulation so they can't say why the bang occurred.

First they junked the concept of "justice.” Examined semantically "justice” has no referent-there is no observable phenomenon in the space-time-matter continuum to which one can point, and say, "This is justice.” Science can deal only with that which can be observed and measured. Justice is not such a matter; therefore it can never have the same meaning to one as to another; any "noises” said about it will only add to confusion.
But damage, physical or economic, can be pointed to and measured. Citizens were forbidden by the Covenant to damage another. Any act not leading to damage, physical or economic, to some particular person, they declared to be lawful.

Hewson: I ask the Prime Minister: if you are so confident about your view of Fightback, why will you not call an early election?
Keating: The answer is, mate, because I want to do you slowly. There has to be a bit of sport in this for all of us. In the psychological battle stakes, we are stripped down and ready to go. I want to see those ashen-faced performances; I want more of them. I want to be encouraged. I want to see you squirm out of this load of rubbish over a number of months. There will be no easy execution for you. You have perpetrated one of the great mischiefs on the Australian public with this thing, trying to rip away our social wage, trying to rip away the Australian values which we built in our society for over a century.

There are those who are going to be disappointed when no life is found on other planets. Not I - I want to be reminded and delighted and surprised once again, through interplanetary exploration, with the infinite variety and novelty of phenomena that can be generated from such simple principles. The test of science is its ability to predict. Had you never visited the earth, could you predict the thunderstorms, the volcanoes, the ocean waves, the auroras, and the colorful sunset? A salutary lesson it will be when we learn of all that goes on on each of those dead planets - those eight or ten balls, each agglomerated from the same dust cloud and each obeying exactly the same laws of physics.
