View Full Version here: : Giant Impacts not Periodic
03-08-2011, 07:48 PM
An interesting article by Phil Plait (http://blogs.discovermagazine.com/badastronomy/2011/08/02/new-study-finds-giant-impacts-arent-periodic/#more-35307) on recent study (http://www.mpia.de/Public/menu_q2e.php?Aktuelles/PR/2011/PR110801/PR_110801_en.html) which poses the question:
"Does the impact rate for asteroids and comets vary periodically with time?"
Interesting also is Bailer-Jones words about Bayesian inference (similar to what was outlined in our thread about (http://www.iceinspace.com.au/forum/showthread.php?t=78756) Speigel's paper about the probability of abiogenesis).
Bailer Jones says ..
Oh … and yes .. the conclusions:

This post has less to do with impact cratering than it has to do with your belief about Bayesian statistics (and, ultimately, chaos theory).
Craig, I'm getting sick and tired of these posts of yours lately that are out to look for nothing but controversy. All you're doing is pushing your own little barrow here about a theory (or methods) that have become a bee under your bonnet. Instead of looking for articles to use to push your pet ideas, find some we can all enjoy reading without them degrading into pointless arguments. These debates are becoming tiresome and annoying. That's all I'm going to say on this matter.

Carl dont let it upset you....and to hold your resolve not to say more on the matter would be perhaps a good approach if it continues to annoy you...
Thanks Craig its new to me and presumably others.
Thank you for taking the time to find material to provide content here... it is not easy to find new stuff I guess otherwise we would have many new threads each day...
best wishes to all and let peace and calm guide your thoughts and actions.

I'm just tired of people pushing agendas, Alex. This is not a forum for pushing agendas. I've made my point of view very clear in other threads. I'm not going to repeat myself here.

I have only one agenda … to explore and learn as much as is possible.
I only hope that others are interested in the same.

Yes I can understand how you feel Carl but agenda pushing is what humans do best ...I just dont like to see you upset.
If we have a particular interest..say gravity for example:D.. it may appear to others we are obsessed about that interest and pushing a particular idea whereas I suggest it is more a matter of sharing with friends ideas you think they will find as interesting as you find them.
I am thick so I havent noticed any friction but when I do it really upsets me when I perceive such...
Thanks for taking the time to comment have a great day.

Well Craig in spite of my obsession with how gravity works that is where I come from.
I am fortunate to have folk around me who hold very strange ideas and determined to convert others and so I have learnt not to argue...which is strange..arguing is a joy for me.
When I became more relaxed I realise these folk are only trying to share something with me... because I seem interested they seek me out to let me know of their latest idea...planet x arrives in June..whatever... but I see it as a good thing as they see me as a guy who they can confide in... so rather than feeling trapped I feel special to be in these folks confidence and trust.
So as I have suggested many times we create our reality to a large degree by how we classify what is going on....
