Scientists, therefore, are responsible for their research, not only intellectually but also morally. This responsibility has become an important issue in many of today's sciences, but especially so in physics, in which the results of quantum mechanics and relativity theory have opened up two very different paths for physicists to pursue. They may lead us - to put it in extreme terms - to the Buddha or to the Bomb, and it is up to each of us to decide which path to take.

Shallow ecology is anthropocentric, or human-centred. It views humans as above or outside nature, as the source of all value, and ascribes only instrumental, or 'use', value to nature. Deep ecology does not separate humans - or anything else - from the natural environment. It does see the world not as a collection of isolated objects but as a network of phenomena that are fundamentally interconnected and interdependent. Deep ecology recognizes the intrinsic value of all human beings and views humans as just one particular strand in the web of life.

Subatomic particles do not exist but rather show 'tendencies to exist', and atomic events do not occur with certainty at definite times and in definite ways, but rather show 'tendencies to occur'.

A diverse ecosystem will also be resilient, because it contains many species with overlapping ecological functions that can partially replace one another. When a particular species is destroyed by a severe disturbance so that a link in the network is broken, a diverse community will be able to survive and reorganize itself... In other words, the more complex the network is, the more complex its pattern of interconnections, the more resilient it will be.

For children, most importantly, being in the garden is something magical.

Bells theorem dealt a shattering blow to Einsteins position by showing that the conception of reality as consisting of separate parts, joined by local connections, is incompatible with quantum theory... Bells theorem demonstrates that the universe is fundamentally interconnected, interdependent, and inseparable.

The creativity and adaptability of life expresses itself through the spontaneous emergence of novelty at critical points of instability. Every human organization contains both designed and emergent structures. The challenge is to find the right balance between the creativity of emergence and the stability of design.
