Good Will Newton

Any relation, Will? To Newton?

Title: Towards a Better Understanding of Nuclear Matter: Synthesizing Neutron Star Observations and Nuclear Experiment


10.00 Choco- bacon. Seems to be for shock effect. Didn’t have breakfast this morning, so it has a slightly different effect on your blogger.
10.01 Blaming Google for his representation of nuclear physicists. Crowd appreciates the friendly start to the talk. A little chit chat is nice before… you know. Take note, kids.
10.02 Arrows everywhere. Interdependence between subfields. We get it. It takes a village.
10.02 J0737-3039 Double pulsar, A & B. Looks like my flight number. 22.7 ms and 2.77 s rotational periods for the two pulsars, respectively. Opposites attract, I guess.
10.03 Did someone say--- muuuurder?? My idea of using crime as a metaphor for nuclear physics is being carried to fruition here. I was thinking more along the lines of a mafia syndicate ande cooked books to describe the discrepencies between the Hamiltonians we construct and what Nature uses.
10.06 e-capture is Will's fall guy for pulsar B formation, and crime of double homicide. There is no statute of limitations here. He is going to lay out the case and take it to the jury. Who killed Pulsar B??
10.10 Wrapping up SNe feature list.
10.13 Distinguishing the rest mass and measured mass of pulsar, which is going to include gravitational binding energy of star. EOS is relevant. M_0/R is relevant here.
10.15 Aw- I really don’t feel like listening to EOS crap. Shouldn’t do that to people before noon, Will. Ya- I’m talking to you, man. EOS slides are ALWAYS boring. It is the only thing worse than spectroscopic factors.
10.16 Isospin asymmetries are “alpha.” Should be nice and confusing.
10.18 Symmetry energy discussed, with list of recent studies.
10.21 Zero minutes left warning is interpreted by Will as ~ 5 minutes left. Common approximation for theorists and crazies. (He's a theorist.) Will made the mistake of assuming the session chair was giving other warnings, too. Ahem.
10.24 Constraints are zeroing in on symmetry energy and mass….
10.26 “…final note,….”
10.27 Questions: tolerance for fallback? Simulations of the SNe explosion give E-3 M_solar if any at all. Will recommends seasoning his slides with salt. You should take most of what he says with a grain of salt: he's Brittish. Hendrik: wouldn’t we expect this to happen more frequently given how common e-capture SNe are? Zach: difference in frequencies for A and B…? Spin up of one from L transfer from the other. (Zach is a shoo-in for the student with the most zeal for asking questions. It is a cry for help- just not the kind you think.)

  1. Yeah, I hate having to show EoS slides too. I was going to try and offset this by having smiley faced neutron and protons in nuclear matter, but I ran out of time....

  2. To date I've seen at least 4 different symbols for isospin asymmetry, each one of which is also used to mean something else in related nuclear theory - it drives me crazy. In future I'm going to use that symbol that Prince used for a while.

    Talking of which (crazy, not Prince), I prefer to think of myself as a crazie (with an ie) rather than a theorist.

  3. Hmmm, looks like Will's not the only space scientist with a Newton connection...?
