Behind it all is surely an idea so simple, so beautiful, that when we grasp it - in a decade, a century, or a millennium - we will all say to each other, how could it have been otherwise? How could we have been so stupid?
John Archibald WheelerRead
No phenomenon is a real phenomenon until it is an observed phenomenon.
Interpretation
Observation is crucial for defining and understanding phenomena in the universe.
This quote by John Archibald Wheeler emphasizes the fundamental role of observation in the realm of science and physics. It suggests that a phenomenon only gains significance and reality when it is observed, highlighting the interplay between measurement and existence in scientific inquiry. This reflects a philosophical understanding that our perceptions and interactions with the universe shape our knowledge of it.
In practice
In a lecture on quantum mechanics, one might point out this quote to illustrate the significance of measurement.
Behind it all is surely an idea so simple, so beautiful, that when we grasp it - in a decade, a century, or a millennium - we will all say to each other, how could it have been otherwise? How could we have been so stupid?
In order to more fully understand this reality, we must take into account other dimensions of a broader reality.
In any field, find the strangest thing and then explore it.
We will first understand how simple the universe is when we recognize how strange it is.
The laws of physics that we regard_x000D_ as 'sacred,' as immutable, are anything_x000D_ but.
The universe gives birth to consciousness, and consciousness gives meaning to the universe.
People are going to buy cheap fertilizer so they can grow enough crops to feed themselves, which will be increasingly difficult with climate change.
This [climate change] is potentially so dangerous that we have to act strongly. Do we want to play Russian roulette with two bullets or one?
People have always asked whether evolution is constantly driving onwards and upwards. Is there always going to be improvement? The answer is no: evolution is a progression of form and function, but it is not purposeful.
When you look at the calculation, it's amazing that every time you try to prove or disprove time travel, you've pushed Einstein's theory to the very limits where quantum effects must dominate. That's telling us that you really need a theory of everything to resolve this question. And the only candidate is string theory.
If you've been wondering where the next gold rush is going to take place, look up at the night sky to our closest celestial neighbor. The next economic boom might just be a mere 240,000 miles away on the bella luna.
When you're in a spacecraft, you need to know what things you can touch and what things you shouldn't touch!
