An independant reality in the ordinary physical sense can neither be ascribed to the phenomenon nor to the agencies of observation.
Niels BohrRead
When asked ... [about] an underlying quantum world, Bohr would answer, 'There is no quantum world. There is only an abstract quantum physical description. It is wrong to think that the task of physics is to find out how nature is. Physics concerns what we can say about Nature.'
Interpretation
What this quote means
This quote emphasizes that physics describes nature through abstractions rather than revealing an ultimate reality.
Niels Bohr's quote highlights the distinction between the tangible world of nature and the abstract representations that physics provides. He argues that physics should not be viewed as a means to uncover the true essence of reality but rather as a discipline focused on the predictive descriptions and relationships that we can observe and articulate about nature, suggesting that our knowledge is inherently limited to these abstractions.

There are no black holes - in the sense of regimes from which light can't escape to infinity. There are however apparent horizons which persist for a period of time.

The universe is a symphony of strings, and the mind of God that Einstein eloquently wrote about for thirty years would be cosmic music resonating through eleven-dimensional hyper space.

What I tend to do is to wake about five in the morning-this happens quite often-think about the invention, and then image it in my mind in 3D, as a kind of construct. Then I do experiments with the image...sort of rotate it, and say, 'Well what'll happen if one does this?' And by the time I get up for breakfast I can usually go to the bench and make a string and sealing wax model that works straight off, because I've done most of the experiments already.

'Goals' and 'caps' on carbon emissions are practically worthless, if coal emissions continue, because of the exceedingly long lifetime of carbon dioxide in the air.

What works most effectively for quelling disease outbreaks like Ebola is not quarantining huge populations. What works is focusing on and isolating the sick and those in direct contact with them as they are at highest risk of infection. This strategy worked with SARS, and it worked during the H1N1 flu pandemic.
