It's really amazing, the quantum world.... the wave particle duality..... that is, an object or rather, light or electrons can behave both as a wave and/or a particle....

Without the presence of an observer, the object behaves as a wave do.....

In the act of observation, it takes on the behavior of a particle....

The waves can be seen as probability function whereby the particle will appear in that particular space.....

Amazing....

Bohr said the act of measuring the levels of quantum energy gave rise to the discrete levels of quantum energy....

If you do not measure... then the discrete levels do not appear......

much like what the philosopher said in the previous post, that one only exists when one is observed or seen...

when one is not being seen.... we only exists as a wave of probability till the act of observation is being done...

haha, confusing? that's the quantum world for you....

I think we should try to practise what Lao Tze said.... Hmm.. I can't really remember what he said... but is something along this line.... to learn, you have to unlearn... sometimes too much knowledge clogged our minds.... for a keen mind is always an open mind..... What is really true ? What is the real reality? who is to know.... we once thought the earth was flat.... We once thought that gravity was all there is, but there came electromagnetic waves and fields.... We once thought light was just a wave... or particle.... or can only be a particle or a wave...... We once thought time was constant....and still think time is.... I think we have to understand, to know, to believe that we will never understand, we will never know anything, and that nothing for sure is certain... and that there are indeed higher dimensions that we can never fathom of and understand with our limited senses and experience.....
