Lawrence Livermore scientists, in conjunction with international
researchers, have discovered five new atomic nuclei to be added the
chart of nuclides.

The study, conducted this fall, focuses on developing new methods of
synthesis for super heavy elements. The newly discovered, exotic
nuclei are one isotope each of heavy elements berkelium, neptunium
and uranium and two isotopes of the element americium.

Other participants include scientists from Manipal University, India;
GSI-Giessen, Germany; Justus Liebig University Giessen, Germany;
Japan Atomic Energy Agency; and the joint Institute for Nuclear
Research in Russia. The results are published in the journal Physics
Letters B. The Lab's Dawn Shaughnessy, Ken Moody, Roger Henderson and
Mark Stoyer participated in the experiments.

The more natural linkage between terrestrial sciences at this level and astronomy is not conjectured particles but rather efficiency at a small scale as a means to discern large scale efficiency such as stellar evolution, orbital dynamics and so on.

You wouldn't think that the growth of a small crystal can tell you anything about stellar evolution but long before the rings of supernova 1987a were observed, I had been working on a geometry where a star is surrounded by two large rings and a smaller intersecting ring back in 1990 using a very specific geometry borrowed from quasicrystal growth -

I'll let you into a secret experienced by many innovators. There is a private side and a public side to creativity for while the former sometimes comes as a blinding flash or at other times as a slow and almost imperceptible adoption of perspectives, the public translations of new insights into new narratives is often a rocky road.

I could show you the master geometric representation bridging quasicrystal growth with an encompassing geometry governing all natural efficiency and beauty up to an including stellar evolution but the geometry will mean absolutely nothing to you and your colleagues who basically practice a modern form of voodoo -

The arrangement where 36°,72°,108° and 144° fall into sequence within a structure balanced between pentagonal and hexagonal geometry forms a wonderful story that has developed in a wonderful way over the last 3 decades.

The chances are that the story will die with me as people mistake contrived novelties for genuine mysteries even though genuine researchers sometimes make advances as with stellar evolution.

Let me guess, they have half-lives measured in micro-seconds?

The participants? How did they find time to do the experiment?

I think these days they have gone even further towards scraping the bottom of
that particular barrel. Perhaps nanoseconds. I don't think they've gotten to
picoseconds, let alone femtoseconds, just yet.

Ah, the article says the particles thus formed fly apart after a sextillionth of a second.

microsecond: 10^-6
nanosecond: 10^-9
picosecond: 10^-12
femtosecond: 10^-15
attosecond: 10^-18

million: 10^6
billion: 10^9
trillion: 10^12
quadrillion: 10^15
quintillion: 10^18
sextillion: 10^21

Oh, dear me, it's not only not a femtosecond, it's not even the next one after!
Of course, the particles, just being formed by two nuclei crashing into one
another, may be in an excited state, so the actual half-life of the isotope,
were it possible to cool down the nucleus to see, might be longer.

Their half lives, though, it seems at this point, would be measured in
zeptoseconds, if one takes them as they are.

Better this, I suppose, than scientific research into the behavior of gambling apes. (Maybe there should be a special tax on gambling casinos to pay for that?)

The article says the half lives range from a few milliseconds to a few
seconds. Actually, that's rather longer than I would have expected.

Read all ab-at id! Snellfish recommends increased taxation on gambling!

My statement was in the form of a question, and it suggests that if any group of people should be taxed to fund studies on gambling then that group should consist only of those who actually gamble or who live in areas or work in industries that stand to benefit from gambling (or be harmed by it.)
