I don't think it's egregious at all. We use terms like "gnocchi phase", "lasagna phase", and neutron-star mountains regularly in the nuclear-matter literature, so these aren't indi…

Just a clarification: A here doesn't mean Angstroms. It means "number of nucleons", as in carbon-12 is an A=12 system. So they're saying A>300 means "a quark system with >900 quark…

The udQM they're talking about is in a very different regime than the quark matter produced at RHIC (Relativistic Heavy Ion Collider) and other colliders. In those, heavy ions are …

Yes, one could phrase it that way... but keep in mind that all these theoretical models suggesting an "end to the table" make huge assumptions that are not well-grounded in experim…

No, they mean that cosmic rays would be udQM (presumably produced somewhere in the universe and accelerated to us somehow). The premise of the paper is that you need a large number…

Neutrons are a pain to control as a beam because they have no charge, so methods employing electric or magnetic optics are not applicable. Typical pocket sources use the alpha(9Be,…

Check the Nature paper (and I think this is one of the biggest take-aways from AlphaGo Zero): "Finally, it uses a simpler tree search that relies upon this single neural network to…

I chose a coincidentally easy problem (whoops). Here's another one, less accessible to attack: Find e^7. Or 25000^(1/8). The trick to using the musical scale is that it's logarithm…

Back in 2010 I ran across Sanjoy's method for using the musical scale to perform more complicated arithmetic (mentally calculate pi^6 +/- 5% within 30 seconds). Can't wait to read …

I'm using CAEN (Italian company) digitizers in nuclear research, and I've expended at least 6 months sussing out firmware problems for our simple experiments. [x++] italians
