like with those home ice cream makers (where you crank it by hand... etc) How much colder does the salt make the ice? Does it lower the temp by only a few degrees or is it a decent amount like 10 or more degrees difference?

I hope I worded this so you all can understand what I am trying to say......

The “scientific method” is as follows: Observe what happens; based on those observations, form a theory as to what may be true; test the theory by further observations and by experiments; and watch to see if the predictions based on the theory are fulfilled. Is this the method followed by those who believe in and teach evolution?

Astronomer Robert Jastrow says: “To their chagrin [scientists] have no clear-cut answer, because chemists have never succeeded in reproducing nature’s experiments on the creation of life out of nonliving matter. Scientists do not know how that happened.”—The Enchanted Loom: Mind in the Universe (New York, 1981), p. 19.

Evolutionist Loren Eiseley acknowledged: “After having chided the theologian for his reliance on myth and miracle, science found itself in the unenviable position of having to create a mythology of its own: namely, the assumption that what, after long effort, could not be proved to take place today had, in truth, taken place in the primeval past.”—The Immense Journey (New York, 1957), p. 199.

According to New Scientist: “An increasing number of scientists, most particularly a growing number of evolutionists . . . argue that Darwinian evolutionary theory is no genuine scientific theory at all. . . . Many of the critics have the highest intellectual credentials.”—June 25, 1981, p. 828.

Physicist H. S. Lipson said: “The only acceptable explanation is creation. I know that this is anathema to physicists, as indeed it is to me, but we must not reject a theory that we do not like if the experimental evidence supports it.” (Italics added.)—Physics Bulletin, 1980, Vol. 31, p. 138.

Are those who advocate evolution in agreement? How do these facts make you feel about what they teach?

The introduction to the centennial edition of Darwin’s Origin of Species (London, 1956) says: “As we know, there is a great divergence of opinion among biologists, not only about the causes of evolution but even about the actual process. This divergence exists because the evidence is unsatisfactory and does not permit any certain conclusion. It is therefore right and proper to draw the attention of the non-scientific public to the disagreements about evolution.”—By W. R. Thompson, then director of the Commonwealth Institute of Biological Control, Ottawa, Canada.

“A century after Darwin’s death, we still have not the slightest demonstrable or even plausible idea of how evolution really took place—and in recent years this has led to an extraordinary series of battles over the whole question. . . . A state of almost open war exists among the evolutionists themselves, with every kind of [evolutionary] sect urging some new modification.”—C. Booker (London Times writer), The Star, (Johannesburg), April 20, 1982, p. 19.

The scientific magazine Discover said: “Evolution . . . is not only under attack by fundamentalist Christians, but is also being questioned by reputable scientists. Among paleontologists, scientists who study the fossil record, there is growing dissent.”—October 1980, p. 88.

What view does the fossil record support?

Darwin acknowledged: “If numerous species . . . have really started into life at once, the fact would be fatal to the theory of evolution.” (The Origin of Species, New York, 1902, Part Two, p. 83) Does the evidence indicate that “numerous species” came into existence at the same time, or does it point to gradual development, as evolution holds?

Have sufficient fossils been found to draw a sound conclusion?

Smithsonian Institution scientist Porter Kier says: “There are a hundred million fossils, all catalogued and identified, in museums around the world.” (New Scientist, January 15, 1981, p. 129) A Guide to Earth History adds: “By the aid of fossils palaeontologists can now give us an excellent picture of the life of past ages.”—(New York, 1956), Richard Carrington, Mentor edition, p. 48.

What does the fossil record actually show?

The Bulletin of Chicago’s Field Museum of Natural History pointed out: “Darwin’s theory of [evolution] has always been closely linked to evidence from fossils, and probably most people assume that fossils provide a very important part of the general argument that is made in favor of darwinian interpretations of the history of life. Unfortunately, this is not strictly true. . . . the geologic record did not then and still does not yield a finely graduated chain of slow and progressive evolution.”—January 1979, Vol. 50, No. 1, pp. 22, 23.

A View of Life states: “Beginning at the base of the Cambrian period and extending for about 10 million years, all the major groups of skeletonized invertebrates made their first appearance in the most spectacular rise in diversity ever recorded on our planet.”—(California, 1981), Salvador E. Luria, Stephen Jay Gould, Sam Singer, p. 649.

Paleontologist Alfred Romer wrote: “Below this [Cambrian period], there are vast thicknesses of sediments in which the progenitors of the Cambrian forms would be expected. But we do not find them; these older beds are almost barren of evidence of life, and the general picture could reasonably be said to be consistent with the idea of a special creation at the beginning of Cambrian times.”—Natural History, October 1959, p. 467.

Zoologist Harold Coffin states: “If progressive evolution from simple to complex is correct, the ancestors of these full-blown living creatures in the Cambrian should be found; but they have not been found and scientists admit there is little prospect of their ever being found. On the basis of the facts alone, on the basis of what is actually found in the earth, the theory of a sudden creative act in which the major forms of life were established fits best.”—Liberty, September/October 1975, p. 12.

Carl Sagan, in his book Cosmos, candidly acknowledged: “The fossil evidence could be consistent with the idea of a Great Designer.”—(New York, 1980), p. 29.

It takes a pipe 12 hours to fill a tank when the faucet at the base of the tank is open. If the faucet is opened 2 hours after the pipe had started running, 3/4 of the tank is filled after an hour. How long will it take the faucet to empty a half-filled tank if the pipe is not running?

I understand the majority of it e.g.
I used a total of 629 kWh over 77 days.
The statement says that the first 190 of these were charged at 16.383 pence (£31.13) and the next 439 were charged at 8.491 pence (£37.28) for a total of £68.41p

What confuses me is this additional information on the statement:
'How we calculate your electricity charges: 16.383 pence per kWh for the first 2.466 kWhs used a day, and 8.491 pence per kWh for the rest.'
To me this implies that the first few kWhs of electricity used each day are charged at the higher rate and those that are used after this are charged at the lower price (for the rest of the day). Now I've been told that this relates to night useage (cheaper) and day useage (more costly) but how does my 'service provider' separate my useage into kWhs used up to 2.466 kWhs? Am I thinking about this in the wrong way?
