If the UTC-TAI offset remains at -37s, then it also means the UTC-GPS offset remains at -18s. TAI and GPS have a constant 19s offset from each system.

I concur with building picoballoons. It's much more economical. It's hard to recover from a malfunctioning rocket that carried your precious payload, but a burst Yokohama is just a learning lesson.

The current zeitgeist is clearly anti-plastic. Only time will change their minds. Fortunately, the healthcare industry (hospitals) will always use plastic for preventing contamination in a very economical way.

NASA is a great PR firm. In my opinion, the real heroes are CalTech-JPL, Arizona State, and the other institutions that NASA slaps their logo on to.

The cover reminds me of John Harris's _A Dream of Starlight_.

KboPAacDA3 — Thu, 23 May 2024 18:13:56 +0000

It's the current trend in selling the fear of climate change caused by fossil fuels. People get desensitized to prior campaigns, like oil drilling, pipelines, gasoline cars, and plastic bottles in the ocean and straws in the rivers. Microplastics push the fact there's something foreign in your own body, and that's disgusting.

Martin personally gave me a tour of the factories back in 2002. I got to see first hand things being made from parts. I overheard him pitching an idea to an engineer, and then a year later seeing the product reviewed in QST. I still use the clock he gave me.

KboPAacDA3 — Wed, 03 Apr 2024 14:52:36 +0000

The key reason is the Coordinated part. By letting the Moon handle it's own timekeeping, it reduces the hassle of getting regular updates from Earth clocks. Earth-based atomic clocks will continue to measure its own precise second lengths and take measurements of quasars to get accurate wall-clock time. Moon-based atomic clocks can have their own separate network of atomic clocks and measure the same quasars to get the same wall-clock time.

You seem to have read the Old Testament. I would encourage you to also read closely the New Testament. In Matthew 23:23, Jesus affirms we should give tithes as well as justice and mercy. As for homosexuality, read Romans 1.

It's no longer necessary to follow the Mosaic law because Jesus fulfilled the requirements of the law and paid for the sins of his people. If you would like an in-depth answer, google: why do we no longer follow the mosaic law.

New comment by KboPAacDA3 in "Ask HN: Librarians, how do you find books to buy"

KboPAacDA3 — Sun, 16 Oct 2022 03:44:58 +0000

For an academic library, we interact with the faculty to find out what they want. Their departments are given a budget and we buy what they want.

For a public library, we get input from the public and also read Publisher's Weekly. We may get a curated title list from publishers on various subjects.

We regularly generate reports on what is being read and checked out, but those are mainly meant to determine what to remove from the shelves.

Thank you for writing this article and especially skipping the unneeded proofs that a programmer usually has to step over to apply quaternions.
