Superman123 Posted January 22, 2012 Report Share Posted January 22, 2012 (edited) “Don’t tell me it’s impossible; tell me you can’t do it. Tell me it’s never been done… the only things we really know are Maxwell’s equations, the three laws of Newton, the two postulates of relativity, and the periodic table. That’s all we know that’s true. All the rest are man’s laws.” – Dean Kamen, inventor of the Segway and recipient of the National Medal of Technology and Lemelson-MIT Prize. This quote really struck me. It really got me wondering if this is true? I presume he is talking of Physics and Chemistry. Is everything else, except these things he mentions, we know theories we ourselves have developed with our own experience and thought?

dream_weaver Posted January 22, 2012 Report Share Posted January 22, 2012 (edited) The quote looks pretty selective. What was omitted? As to even physics and chemistry, the theories were developed in conjunction with man's experience and thought. The Logical Leap by David Harriman illustrates the essentials of this process using examples from both physics and chemistry.

Nigel Posted January 22, 2012 Report Share Posted January 22, 2012 NO! First off, science is theory... Everything that is important or worthwhile is theoretical. Read up on the philosophy of science if you are interest. Anyways these things that are claimed to be know as fact are actually theoretical. We cannot directly observe atoms, they are theoretical (though atomic theory is very sound and plausible, it is still by nature theoretical). We develop theories based on observed reality. There are ways to evaluate the plausibility of these theories, but to accept theories to explain reality is not contradictory to embrassing reality.

dream_weaver Posted January 22, 2012 Report Share Posted January 22, 2012 Yes, we can: http://physicsbuzz.p...s-of-atoms.html Are you sure this is not relying on our knowledge of photography, field-emmission electron microscopes, and other elements involved in establishing this fact?

I wonder what distinction he is trying to make. He refers to Maxwell's laws, those are a man's laws but somehow those are different from Kepler's laws of planetary motion.

Superman123 Posted January 23, 2012 Author Report Share Posted January 23, 2012 I am wondering what is his purpose for listing these few things as 'true'. Does somebody have an idea why? You cannot be 100% sure of anything in scientific thinking. Quote Link to comment Share on other sites More sharing options...
dream_weaver Posted January 23, 2012 Report Share Posted January 23, 2012 (edited) I think he's trying to emphasis or underscore the "Don't tell me anything is impossible; tell me you can't do it. Tell me it's never been done." (Just don't tell me it is impossible.) Newton, and the periodic table are a couple of feats of doing in history that many may have thought were impossible. The refutation is Newton's laws and the periodic table. As to not be certain of anything in scientific thinking, Both Newton's laws and the periodic table provide testimony to the contrary.

Superman123 Posted January 24, 2012 Author Report Share Posted January 24, 2012 (edited) @dream_weaver, A rational skeptic told me that he is not mentioning that Quantum Mechanics. It is one of the most thoroughly tested theories around and that he thinks that this quote is a hankering back to the Renaissance Man and an oversimplified view of science. I do think that I agree. He is rejecting hard earned knowledge and trying to say we do not know much. Isn't this cynicism? Then he wants to poor syrup on it all by implying we can do anything because we know so little. It is interesting. These things are motivating me to read up more about it. I really want to study up Occam's razor and the Philosophy of Science. I think wiki is the best but sometimes their explanations can sometimes become a bit dull. I will see what my local library has.

Grames Posted January 24, 2012 Report Share Posted January 24, 2012 I suspect there is a metaphysical premise lurking behind the quote, that only certain basic and fundamental facts have a real existence while everything else is an effect or illusion and so only those fundamental things are able to be true. It is a metaphysical hierarchy theory. Occam's Razor is not sound because it is not necessary for things to be simple to be true. Quote Link to comment Share on other sites More sharing options...
