Condensate fans and attendees of #apsmarch! Consider sending your abstract (due Oct 25!) to: "Bio-inspired phase-separation" the @ApsDsoft and @ApsDbio focus session I am organizing with @SamWilken_ (session # 02.01.20 or, identically 04.01.39) Thanks!

Another paper from super post-doc @SamWilken_ on DNA nanostars, quantifying the delay for droplet appearance after a quench. The dynamics are consistent with distinct nucleation and spinodal decomposition regimes, and we map the spinodal curve. More here: doi.org/10.1063/5.0204…

Save the date for Single Molecule Biophysics 2025 (SMB 2025) to be held over January 5-10, 2025 (inclusive) at the Aspen Center for Physics, Aspen, Colorado. To get your name on our emailing list, contact tperkins@colorado.edu. Please RT. jila.colorado.edu/smb/

Happy to share our just-published review article on liquids (condensates) formed from nucleic acids. We tried to be pretty comprehensive, yet during the publication process ~6 more papers in the area appeared...ah well. see here, hope you like it: iopscience.iop.org/article/10.108…

@AlexanderRKlotz While I respect your laziness, in practice it is very easy to organize a session

Somebody please make a session about my extremely specific interests without me having to do it.

1) 500 mm lens plus blue band pass filter to knock down intensity, projected on paper 2) tree leaves as pinhole cameras, projected on sidewalk

@mglerner @csantangelo314 @MarkusDeserno Not infinite current. Current impeded by the 100k resistor, or 50k plus internal battery resistance. I think the point of the original problem is initially the time constant is due to series C and 2R, and after switch closes is due to a parallel arrangement

@OASaleh @csantangelo314 @MarkusDeserno But, again, I have the feeling I'm wrong here.

#Physics twitter, what do you think the answer is? I think it's a typo.

@csantangelo314 @MarkusDeserno @mglerner No wait I am wrong Capacitor will charge to 10. Actually the whole thing seems fine; no typo.

@csantangelo314 @MarkusDeserno @mglerner Yeah I think you are right. After a Long time of being open, V will be 10*2/3 at the top point, not 10. Typo in the label of the potential, otherwise it seems well defined.

@yoheinakajima @littmath Oh also your sim seems to be just a single Alice win, with the numbers being points in that win… likely need to repeat it many times

@yoheinakajima @littmath I think fluctuations in absolute number of wins get very large for large trial number, so it is hard to draw conclusions from one sim…

Flip a fair coin 100 times—it gives a sequence of heads (H) and tails (T). For each HH in the sequence of flips, Alice gets a point; for each HT, Bob does, so e.g. for the sequence THHHT Alice gets 2 points and Bob gets 1 point. Who is most likely to win?

@yoheinakajima @littmath I found similar, elsewhere in thread. I think Bob and Alice are equally likely to win when # flips increases towards infinity...

@littmath 10,000 simulations each from 1 to 100 flips.

@littmath In the thermo limit, I think lumpiness disappears-- sequences with long stretches of h's are effective zero probability when flips->infinity, where 'long' means 'a significant fraction of flips' so the simple answer (Bob and Alice equally likely) becomes correct in thermo limit

@littmath I agree with others that Bob winning is due to 'lumpiness' of distributions- many 'hh' pairs are involved in sequences with long stretches of h's (Alice effectively is running up the score in her wins)

We are saddened as we share that Nobel Laureate and emeritus professor Herb Kroemer has passed away. He was 95. The visionary theoretician and experimentalist brought forth ideas that literally changed our world. Read about his pioneering work and tributes engineering.ucsb.edu/news/nobel-lau…

@perrys_lab damn! We had made sure to not get scheduled against other condensate sessions, but missed this...should've gotten a dpoly co-sponsor...sorry to miss you!

@OASaleh I’m so sad this session is at the same time as the Dillon Medal symposium in DPoly. 😭

#apsmarch attendees: Check out session K35, “Bio-inspired phase separation”, Tuesday 3-6pm, with great talks on various condensate/compartmentalized systems, including invited talks from Will Jacobs (Princeton) and Sam Wilken (UCSB) @ApsDsoft @ApsDbio march.aps.org/sessions/K35
