SUMMARY

The discussion centers on the relationship between physics and the concept of life, emphasizing that physics does not define life but rather focuses on the interactions between matter and energy. Participants agree that atoms themselves are not alive; instead, life arises from the information encoded in the arrangements of atoms. The conversation highlights the distinction between physics and biology, suggesting that inquiries into life are better suited for biological sciences. For further exploration, the concept of 'Artificial Life' (ALife) is recommended, along with the book 'Artificial Organisms' for a deeper understanding.

PREREQUISITES
  • Understanding of atomic structure and properties
  • Basic knowledge of biological concepts, particularly cellular functions
  • Familiarity with the principles of physics, especially matter and energy interactions
  • Awareness of the field of biophysics and its relevance to life sciences
NEXT STEPS
  • Research the concept of 'Artificial Life' (ALife) and its implications
  • Read 'Artificial Organisms' to explore the intersection of life and artificial constructs
  • Investigate the principles of biophysics and its role in understanding life
  • Examine the philosophical debates surrounding the definition of life in scientific literature
USEFUL FOR

Students and professionals in physics, biology, and biophysics, as well as anyone interested in the philosophical implications of life and its scientific definitions.

dear readers,
everything in this world is made up of atoms. but how come certain things have life and certain thing don't have. do atoms have life like us? what is pecular about the atoms that cause life?

no one is a expert other than god.who knows every thing?
 
Physics news on Phys.org
There is no "according to physics" here.

Physics quite intelligently avoids the question: it says "I have enough to worry about, go ask biology"!
 
Physics deals with interaction between matter and energy, not life.
 
benzun,
Life is a dicy concept. Even Biologists often find it more conventient to refer to "functioning cells" than "living cells". However, as to your question about whether atoms are alive like us, the answer is most assuredly "no". They meet none of the criteria that are used to determine life.
 
'It is not the atoms themselves, rather the information that is encoded in arrangements of atoms that is the basis of life.' At least this is the viewpoint of many scientists working in the fields evolutionary biology.

The question of how the concept of life fits into physics is a huge field of debate. For more info, I suggest you look up 'Artificial life' (or 'ALife) on google for a different perspective on the question of life, it is rather interseting, even if you do not quite agree with what is being suggested by the ALife movement.

The book 'Artificial Organisms' is also a very good read if you are interested in this kind of thing.

'It is not the atoms themselves, rather the information that is encoded in arrangements of atoms that is the basis of life.'
That is close to my view, which is that life corresponds to a process, a certain form of complicated flow that we can subjectively identify.

But physics doesn't have an official line on this. Physicists disagree a lot over what life represents - as a brief look through the PF philosophy archives would show.
 
That doesn't prevent biophysics from having an active agenda:
