Some Science opinions (random and unconnected)

Random science opinions volume I

1: What kind of person actually believes lights in the sky could be some extraterrestrial visitation. What kind of alien would fly around showing lights if they were trying to hide their presence. If they were not trying to hide their presence why not announce themselves and start some interaction.

2: Some current science disciplines are only slightly removed from art and imagination. What kind of science can describe a 5-ton 200 million year old lizard from a couple crumbling rocks weighing a few pounds? There is a lot of legitimacy in paleontology but imagination also plays a significant part. Paleontologists have a lot of hard evidence but come on, how can they describe the size, shape and lifestyle of an extinct creature from a couple old, rocky bones?

3:Astronomers and astro-physicists like to believe they have a grasp on their subject but their theories are based on imagination filtered through incomplete science. In a way similar to paleontologists, they describe complete systems based on interpretations of measurements with very wide ranges of inaccuracy. The understanding of our universe has not yet reached the equivalent of the earthworm's concept of automobiles. I enjoy the theories but I have always been a fan of science fiction.

4: Psychology is another art and imagination based science. From what I see in the news and TV crime shows (kinda qualifies my opinions, right?) you can always find a psychologist to support your personal opinion on a subject. Any diagnosis is always a personal interpretation based on some hard behavioral science combined with the Doctor's personality.

5:Medicine. Doctors are not allowed to practice their craft the way it should be practiced. The pressures of profit and liability require them to limit the time they spend actually getting the information they need to make accurate diagnoses. With a need to see as many patients as possible in the shortest period of time the average doctor treats the patient's first described symptom and brushes aside anything else. With lawyers lurking behind every patient, every doctor must practice defensive medicine: expensive tests that would not be ordered without the liability threat. As patients we like to believe our doctors are concerned about our well being and know what they're doing. Most doctors actually know what they're doing but get in a habit of quick, simple, defensible diagnoses instead of looking for real problems.
