Science prior to Einstein was basic, and so a basic understanding sufficed. Quote:

Interacting with the physical world today does not give you an understanding of quantum physics or relativity, and it does not give you an understanding of the global self-regulating climate system. (which was so hard for climate scientists to accept for years that they ostracized James Lovelock from the scientific community for pursuing such 'radical' ideas, that are now taught in earth systems courses at universities and colleges).

Re: Sound-bite science
Evolution is not very difficult to understand, it just isn't taught. My 13 year old son has a very good grasp of it, but he didn't learn it in school!

I think the main problem is that the vulgarizing press uses classical concepts to explain non-classical concepts. Take the so-called wave-particle duality. In the popular press (in which I include the vulgarizing science books) the photon is presented a a Magical Shapeshifter that is a wave here and now, and is a particle there and then. But such presentation only obfuscates things. The photon is a thingy that shares some properties with waves and shares some other properties with particles, that's all. It is merely convenient to think of a wave when examining some specific properties of the photon and it's merely convenient to think of a particle when examining some other specific properties of a photon. But a photon never IS a wave and never IS a particle. The analogies that are used to explain it get in the way of understanding instead of vice versa. The 'thingy' I used in the previous paragraph is a problem. There is a word I could correctly use there, viz. 'quantum', but then the 'jargon' argument would pop up again. The new words that are used are deemed too sophisticated and using the old, classical, ones lead to confusion. Therefore, let's start from scratch to explain the basics of quantum physics and the photon: Step 1: When you slice a diamond with a knife, what do you get ? Two smaller pieces of diamond? Correct. Now, what happens if you keep slicing up the remaining pieces ? Can you get ever smaller pieces of diamond ? The answer is no. There comes a point that you are left with a single unit of diamond, that can no longer be divided while still having the properties of diamond. We call this 'thingy' an atom of diamond. Matter is thus not infinitely divisible. Step 2: What about energy ? 'T is a bit more difficult to go slicing up energy so what one did was examining the properties of energy under the assumption that is a continuous stream. But the calculations one made under that assumption turned out to give results that didn't correspond to what one observed in reality. So that assumption had to go. Now, let's assume that, like matter, energy also has a point at which it can no longer be divided without losing its properties and calculate from there. Result : perfect agreement between the theory and the observations. Cool, we got it right this time. Now we'll call this tiniest bit of energy a 'quantum' for ease. Difficult word ? Ok, let's also call it an 'energybit' as in titbit. Step 3: What does an energybit look like ? Well, we can't see it, so let's look at what properties it has. After calculations and experiments, one gets a list of properties A, B, C, D, E, F, G, H, I, and J. Ok, but what does it look like ? Well, the properties D, E, and I are the same properties D, E, and I that a wave has, so for those, and JUST for those, think of a wave and properties A, B, and J are the same properties A, B, and J a particle has so for those properties, and JUST for those, think of a particle. Ok, but what about properties C and G ? Well, those are new, and only an energybit has them, so you'll just have to learn about them and accept them. There you have it, the essence of QP. Now, was this so difficult ? 'Quantum' is no more counter-intuitive than 'atom' is. But 'atom' doesn't give people the shivers because they were taught about them. It's a household name. 'Quantum' would also be if QP was in the general curriculum. Quote:
