36125 140?!  I didn't even know we had names for elements that high! Ah, sorry for using confusing terms. I should have said atomic mass, not 'atomic mass number'. The r-process in neutron star mergers is the dominant way for nuclei with masses greater than about 140 to be synthesized, which corres...

36117 Wow Wat how do you get bird in flight shots? Skagit Valley to the south of me is full of marshes and farmland which make for a bird-watchers' paradise. It's not hard to get good shots out there, and it's common to see a lot of other bird watchers as well, often with very impressive equipment....

36114 Wat, are some of the elements we call "artificial" able to exist for short periods of time when stars explode? Yes, absolutely, and kilonovae (when two neutron stars merge together) are best at both producing and ejecting these heavy elements (especially with atomic masses greater t...

Some nice bird watching today. In addition to the usual eagles, harriers, and herons, there were a pair of short-eared owls skimming about.

36081 Is this accurate?  I really like it and always wanted to see a periodic table like this! It may not be perfect, since our understanding of the different ways these elements are synthesized and dispersed through the cosmos continues to be updated, but it is about as accurate as it can be given...

Unusual weather

36028 Wow that sounds dangerous, did you have to shelter in place, Wat?  4 inches per hour is something I wouldn't want to be caught outside in! It was fine. I was back in my car and starting to drive down before conditions got too bad. Of course, the biggest concerns would be getting caught outsid...

General global warming / climate change discussion

36026 But we haven't yet identified what dark matter or dark energy are yet, it could be that some modified theory of gravity is needed (or quantum gravity) Quantum gravity is almost certainly needed at some point, but probably not in order to explain the effects of dark matter or dark energy (for ...

General global warming / climate change discussion

Is Curry not likewise invested in a particular position? Does it matter? In science we should care most about the quality of the arguments and the evidence supporting them, not the motivations of the people making them. 36021 As Curry puts it: "Relying on global climate models, which don’t adeq...

Unusual weather

I got caught in a rather impressive snowstorm in the mountains today, with perhaps 8-10cm accumulating per hour and frequent thunder (which sounded like it was everywhere at once, being inside of the storm cloud). I've been up there during snow many times before, but this was something to remember. ...

General global warming / climate change discussion

Michael Mann:  The Rise and Fall of the Atlantic Multidecadal Oscillation . Pretty interesting. This will certainly motivate continued study by the broader climate science community, so we'll see how the story progresses. For the moment, though, I think the arguments he has laid out are actually rat...

Roy , okay, then you do not get to participate in this forum any further. FFT likewise asked "why are you even here?" Apparently not to have a respectful discussion with all participants. Respect is something we value at the core of our community. You do not get to raise a fuss about thin...

35974 You can't collect wisdom by a stupid test, sorry. Okay. Not only did you not answer the poll's questions in the prescribed manner ( which every other respondent thus far has managed to do with only a few minor errors), you also did not provide feedback which is constructive or actionable. You...
