Collin not quite getting it:
That is not a contradiction. Light is readily observable even when it is not calculable. Before light was measurable (due to technological limitations), people could observe it and even conduct scientific experiments to test it.
Umm...Collin? You do realize that the early experiments with light (by Alhazen around 965 CE) were based on hypotheses that were tested through...wait for it...measurements:
|Alhazen invested significant time studying light, color, shadows, rainbows, and other optical phenomena. Among this work was a study in which he stood in a darkened room with a small hole in one wall. Outside of the room, he hung two lanterns at different heights. Alhazen observed that the light from each lantern illuminated a different spot in the room, and each lighted spot formed a direct line with the hole and one of the lanterns outside the room. He also found that covering a lantern caused the spot it illuminated to darken, and exposing the lantern caused the spot to reappear. Thus, Alhazen provided some of the first experimental evidence that light does not emanate from the human eye but rather is emitted by certain objects (like lanterns) and travels from these objects in straight lines. Alhazenís experiment may seem simplistic today, but his methodology was ground-breaking: he developed a hypothesis based on observations of physical relationships (that light comes from objects), and then designed an experiment to test that hypothesis. Despite the simplicity of the method, Alhazenís experiment was a critical step in refuting the long-standing theory that light emanated from the human eye, and it was a major event in the development of modern scientific research methodology. |
So what did Alhazen meaure? Why how light actually moves (in a straight line). That's an actual measure, Collin, and he did it by setting up a very simple experiment. He actually defined a specific characteristic of light by conducting that experiment.
Of course, unlike CSI, no one was claiming that the amount of light an object gave off was could be determined and further, that some threshold of that amount indicated that the light was coming from some intelligent source. However, you folks on UD are claiming just that, yet you can't seem to demonstrate such through even a rudimentary experiment.
we IDists rule in design for the flagellum and cilium largely because they do look designed. †Bilbo
