Half Life?
[edit]So, is it years or milliseconds? The fact the old & new numbers disagree so throughly would make an interesting section if someone knowledeble enough stumbled onto this page... Stevefranks (talk) 20:24, 11 March 2015 (UTC)
Vital information missing regarding half-life reference
[edit]The statement "This is far too short for the isotope to survive to the present, - - -" needs elaborating, it infers a very specific point in time when there was Aluminum-26 and now there isn't because time has elapsed. In the article, WHICH point in time is referred to by the author as the beginning point, the Big Bang, the supernova that initiated our solar system, or what? Every little bit of thinking I don't have to do helps speed up how fast I understand something. I am a chemist and I completely understand the concept of half-lives, but off the top of my head I couldn't tell you the relationship between 7.17x10^5 or 717,000 years half-life and the 4.54 billion years that is the approximate age of the earth as far as how many micromoles of Al-26 would be left after that period of time if starting off with one mole. Thank you. Linstrum (talk) 02:54, 15 April 2015 (UTC)
Figures?
[edit]"Figure A shows the relationship between 26Mg/24Mg versus 27Al/24Mg for a system initially containing the element Al with (26Al/27Al)IN in all phases. Figure B shows the observed relationship between 26Mg/24Mg versus 27Al/24Mg in an inclusion from the Allende meteorite.[28]" - what figures? Is it possible that this article is the result of copy&paste from other articles? Some sentences seem to be without context or incomplete (including empty brackets). --StYxXx (talk) 04:35, 17 September 2015 (UTC)
- Commented those figures out, seems an ip added the content, but didn't know how to upload his figs back in June. I've done a bit of fixin' - more needed. Vsmith (talk) 12:54, 17 September 2015 (UTC)
