Nice!
Hey everyone, came across the Cerium LT Hoody at a massive discount at the Seattle Premium Outlets. I'm pretty sure it's mainline stuff. As of this afternoon, there were still size smalls, larges, and x-larges left, all in the green colorway.

There are a few people who have queried why Bob Lazar knows the atomic number of the spacecraft "fuel" (number of protons - 115), but never mentions the mass number (protons + neutrons). This information would be useful because the theory of an island of stability is predicated on getting the number of protons and neutrons correct - thus far, all isotopes of 115 produced are unstable.
Well, there is a diary of Joe Vaninetti (one of Bob's close friends circa 1989) online. This diary notes down information Bob appears to have offered over 8 or so months. This diary states that the atomic weight of 115 is 271.
This would put the number of neutrons at 156. This is basically as far away from the theorized magic neutron numbers of 126 and 184 as you could get. If a 115 sample is to be stable, it is assumed that the neutron shells will be closed at a neutron number of 184. Of course, humans may be way off with our theories on the island of stability...
EDIT: the clowns on r/ufos censored this post on their sub. Why would they do this?
Question: [update in comment]
I've used the Rab Microlight Apline Down Hoody for several years and it has worked well for me. I am able to go on one or maybe two hikes a year (5 - 7 day range)
I'm looking to save weight and maintain/improve performance. (I have never been cold in the Rab Microlight but it is about 16.7 ounces)
What are your thoughts on the Rab Zero G vs Cerium LT Hoody? I recently purchased both in size Large and will keep one of them. (Rab Zero G for $315 + tax and Cerium LT Hoody for $196 + tax)
The aesthetic of the Arc'teryx Cerium LT is superior to the Rab Zero G, but it does not feel nearly as warm and I have some concern over the lack of hydrophobic down. Arc'Teryx items fit me well and the Cerium can definitely be used as a winter jacket around town. This is a positive for my wife.
The Rab Zero G seems like a far superior technical piece that would really only be used for hiking. Is this jacket too warm for only occasional high elevation spring / summer / fall hikes around the United States? I use a less warm down sleeping bag and often sleep in my Rab Microlight and am happy with this arrangement.
Which would you recommend keeping? I plan on using the jacket for occasional backpacking over the next 5 - 10 years. I will still have the Rab Microlight available.
Thanks!
Need a vest for extra layering options. Although will be used for stand alone so I am wondering if anyone has had a poor experience with the Cerium sl series shell fabric vs the atom lt. Or any other options I'm not aware of?
I live in NYC and I have a good winter parka I like. I was thinking about getting a Cerium Lt as a fall/spring jacket. I don't really hike or mountaineer.
I was at the arcteryx store and I tried on a few of the options - Cerium was so light and comfortable and it fits amazingly well. I read through this sub but wasn't sure if it was appropriate for city use during cool dry conditions. I was hoping to get peoples opinions on what it would be like to use Cerium as a fall jacket for city use. What do you guys think?
edit: so when I meant fall/spring i meant temperatures like 40-60. I have an Atom LT that i really like that I think will be warm enough for temperatures higher than that!
edit2: thanks yall for the comments! helped me make a decision - not getting it. Didn't like Thorium's fit or bulk - have to see what I am going to get, but for now Possibly just going to layer under Atom LT.

Tritium, because it has an half-life.
I am having trouble answering this question and would like some guidance:
Germanium has 5 common isotopes, a sample contains the following:
70Ge (57.4%), 72Ge (75.9%), 73Ge (21.3%), 74Ge (100%), 76Ge (21.0%) What is the average atomic mass of the sample?
I just multiplied 70x(0.574) + 72x(0.759) etc. since that is what you normally do. But since the percentages add up to a number higher than 100, should I do anything different? I ended up with 200.39 amu
Hope everyone out there is staying safe.
I am looking to sell this jacket that I've only used on one trip. Like new condition. No tears or rips or any damage/stains. Colorway is Pilot.

Would this layering trifecta be enough for -10 weather skiing? I went with the Cerium Lt because of the light weight, it is really super comfortable, but don't know if it is appropriate for resort skiing? Seems really fragile.
My understanding is that in carbon dating, the age of a fossil is determined by discovering the ratio of carbon-14 to carbon-12, and that carbon-12 is stable and constant. My question is, how do we know the initial ratio of the carbon isotopes?
So for instance, if one organism started off with 10 times the amount of carbon-12 as carbon-14 just before it died, and another organism started off with 5 times the amount, wouldn't their fossils show two different readings of age? Or do all living organisms have the same ratio of carbon-12 to carbon-14 when they die?

It has a delay of 1 minute and only you will get cancer or die (if you can), nobody else will.
Also, they cannot be used on nucler energy or nuclear bombs.
i thought that usually in this type of process the mass number changes. how can it stay 40?
Thought this might interest some of you:
Backcountry's picture makes the color look a little brighter than I believe it is. Here is Arcteryx's youtube video of the same color:
Hope this is helpful. Its 60% off retail so seemed like too good of a deal to pass up.
