Even theories change. Accepted theories are the best explanations available so far for how the world works.
They have been thoroughly tested, are supported by multiple lines of evidence, and have proved useful in generating explanations and opening up new areas for research. However, science is always a work in progress, and even theories change. How? We'll look at some over-arching theories in physics as examples: Classical mechanicsIn the 1600s, building on the ideas of others, Isaac Newton constructed a theory (sometimes called classical mechanics or Newtonian mechanics) that, with a simple set of mathematical equations, could explain the movement of objects both in space and on Earth. This single explanation helped us understand both how a thrown baseball travels and how the planets orbit the sun.
Special relativityClassical mechanics was one-upped by Albert Einstein's theory of special relativity. General relativityEven special relativity was superseded by another theory. Why Do Many Reasonable People Doubt Science? There’s a scene in Stanley Kubrick’s comic masterpiece Dr.
Strangelove in which Jack D. Ripper, an American general who’s gone rogue and ordered a nuclear attack on the Soviet Union, unspools his paranoid worldview—and the explanation for why he drinks “only distilled water, or rainwater, and only pure grain alcohol”—to Lionel Mandrake, a dizzy-with-anxiety group captain in the Royal Air Force.

Chapter 1: THE NATURE OF SCIENCE Over the course of human history, people have developed many interconnected and validated ideas about the physical, biological, psychological, and social worlds.
Those ideas have enabled successive generations to achieve an increasingly comprehensive and reliable understanding of the human species and its environment. The means used to develop these ideas are particular ways of observing, thinking, experimenting, and validating. Activity: Dogs and Turnips. Evolution: Videos for Students: Evolving Ideas.

Do you diligently watch Big Bang Theory reruns?
Sneak into Star Trek conventions in strange cities? While TV’s Big Bang nerds are cast as socially inept, it’s likely the coolest kids would be envious of their social network. Like most things in life, it’s not what you know but how you use it. Time to rethink scientist’s bad rep. Chemist from NYC Tech Day (google???) Characteristics of Science. NSTA Theories and Laws. Laws and Theories Among the Common People. I guess it’s fair to say that the scientific community has not done so well in constructing its jargon vocabulary.
That being said, it’s actually kind of sad how little people know outside of the scientific community, but are so prepared to argue for or against topics that they don’t know much about. I came across an article today that talks about the discovery of a new dinosaur, from which birds may have evolved. You can read about it here: I always like to scroll through the comments just to read what others have to say about the topics I’m reading; but reading these comments was worse than nails on a chalkboard.
