Do current nuclear weapons use complicated interstage devices, like 'radiation bottles' and burn through walls, or were those just for specials tests like Ripple?

I read about those here. Maybe they're deservedly classified and speculative, but are 'pulse shaping' devices not actually necessary for the miniaturized, smaller TN weapons actually deployed, and were maybe just used for large tests to prove a principle? Or they could be part of current TN technology efficiency?

Piano performers: When playing Bach binary pieces, is it cheesy to elaborate the repeat?

There are many of these, and this also applies maybe to early classical period. I'm looking at the gigue Bb Partita. For one thing, when you're about to do the repeat, you think, well I have to at least make it as good. It's kind of lame when the repeat isn't as strong, and you worry the audience might find it tedious to hear an exact repetition. But how about changing the articulation? Or adding ornaments? I'm not sure if we know how these were performed back then, or if it was pretty loose, or the performance practice pedagogy. thanks for any feedback.

Did analysis of fall out from Ivy Mike help Sakharov's Third Idea?

Searching through this sub, I wasn't sure. They learned there was great compression, and lots of neutrons, but did that influence Sakharov's third idea?

Question for pianists playing Bach: long chromatic sequences

It sometimes feels like playing these, like in the cadenza from 5th Brandenberg first movement, or near the end of the gigue from Bb Partita, that it feels lost. I guess it's supposed to be 'briliante' and creates tension from the succession of dim chords going down, like where is it going. Just wondering if any performers have a handle on playing these, which are sometimes quite long. It's not like usual sequences which are more diatonic and shorter. Just play it strait, realizing the listener might feel a little lost about where it's going. Or articulate it in a certain way...

Electric piano is gone from my instrument choice

Sib version 2024.3.1 Previously electric piano was available as a pre packaged sound. It's not there now. Is this a change anyone has noticed?

Closed vs open position triads, more idiomatic?

I'm writing for guitar, and even bought a guitar to help with fingering (I'm a keyboardist, though grew up with a classical guitarist in the family). I see both closed and open position triads in guitar pieces, but is it true that open position is better voicing? And 8va preferable over ledger lines? thx for any info.

Advice for long diminished chord sequences in Bach

I always try to not play Bach mechanically, per audience feedback. Sometimes long diminished chord sequences, I don't know how to play those. I'm referring Bb partita, the Guigue, the second part leading part leading to the ending. The dim chord thing repeats nine times. Any advice on how to play that musically? I know one solution is, at a fast tempo it's often played at, it goes by quickly. But I play it at a slower tempo, so it's more of an issue. Also with the Minuet from the G major partita. About half way through the second part, there is another long sequence I have same issue with. (That's an amazing piece. It's a minuet, but it's in double, compound meter, and it has an hemiola section near the end where it switches to tuple rhythm. Very nice piece. ) Thanks for any tips. I'm performing these two Friday night.

(Using safari 26.4, osx Tahoe 26.4.1)

I have two older hotmail accounts (yes, they'e that old) which people have actually been sending emails to, but which I haven't used in over 5 years. They had security flags back then, and whenever I try to recovery them, outlook throws difficult security questions on my existing outlook account. Is there a way to access these older accounts without compromising my new account? thx for any help.

I'm a classical composer in USA. I'm sure some classical guitarists in Japan speak English, but often the platforms (and I'm not on much social media unfortunately) to reach them are in Japanese. I would like contact classical guitarists about a piece I wrote. Any suggestions? Thank you.

Hello. My son's an experienced composer, and is writing a clarinet quartet (ie, 4 clarinets, not the older term for piano, violin etc.) We've studied lots of repertoire, but what would be a better choice, for readiness for a group to perform it. Two Bb clarinets, one Eb clarinet, and a bass clarinet? Or three Bb clarinets and one bass clarinet? He says the music could be adapted for either, but ideally to know before hand. Thank you for any advice.

Also, it's confusing how the term 'clarinet quartet' often brings up the classical era combo, and not 4 clarinets. Is there standard term you folks use for 4 clarinet combo, aside from 'clarinet choir'?

Logic 12.0.1, OSX Tahoe

I've used clarinet sounds from Logic before. The appropriate sound library is installed. But now I can't find where they are. One of the sound libraries has an option 'orchestra/woodwinds' but it seems to have disappeared. How do I explore the sound library to find it? Sound library search function is pretty weak. thanks for any ideas.

I read the chapter on the 'Garwin design' in Ken Ford 's book , and was wondering. How did they weigh the engineering complexity of cryogenically cooling the Deuterium, to have an easier- to- predict fusion? When Rhodes or Ford of other writers describe the components (the outer wall, the plastic, the natural Uranium, the Deuterium, the spark plug,) it's never mentioned exactly how or exactly where the cooling system 'layer' fits into the design. It's right where all the compression and heating is so it was easy to fit that in there? (Dah, that must sound stupid!) They must have been superb engineers in addition to being superb physicists. Never heard of an internal debate on whether to have a design without the cooling system.

I spoke here last year of a guitar piece I was writing. Here is the Sibelius generated video/audio of this piece. It's finished, parts ready to go! It has throughout a wide triplet figure, spanning an octave or more. I figured it out on a guitar I have (though I'm not a guitarist), but not sure how difficult that is. Appreciate any feedback. Regards...
