- 623463a2a8a949e0590ffe6b2fd3e4e1028b2b99c747e82e899da4485eb0b6be and 5143cf232576ae53e8991ca389334563f14ea7a7c507a3e081fbef2538c84f6e both have 3,075 outputs of 1 satoshi each and a single input. We were not able to identify any meaningful data in it,
filejust saysdata, and there aren't long ASCII strings. However, the outputs were unspent as of 2021, which suggests that they might actually be data.
Analysis of some of them follows.
- dd9f6bbf80ab36b722ca95d93268667a3ea6938288e0d4cf0e7d2e28a7a91ab3 has 13107 with payload 256KB in size, but some of them at least have been spent: www.blockchain.com/btc/tx/dd9f6bbf80ab36b722ca95d93268667a3ea6938288e0d4cf0e7d2e28a7a91ab3 therefore it's not data.
filesays their payload is a DOS executable, but it must be a coincidence

A Baidu Baike page: baike.baidu.hk/item/層層水瀾/12386243 mentions that the score was published in 1970 by Tao Yimo (陶一陌) in a eponymous score book.
Basically a mini-Constellation.
royalsociety.org/grants-schemes-awards/awards/copley-medal/ says it is now open to international citizens, but having a quick look at the 2010 awards still suggests that it is very British centric, or at least anglophone centric, much like the society fellowship itself. That's likely the reason why the Nobel prize won, being much more international from the start.
Coral of life by János Podani (2019)
Source. Fantastic work!!! Some cool things we can easily see:Named after radio pioneer Heinrich Hertz.
Based on JCVI-syn3.0, they've added a few genes back to give better phenotypes, including slightly faster duplication time. Because the development cycle time is your God is also true in biology.
As of essential metabolism for a minimal cell (2019) it had only 91 genes of unknown function! So funny.

JCVI-syn3A during cell division by David Goodsell (2022)
Source. A description is present at: cdn.rcsb.org/pdb101/goodsell/2022_JCVI-syn3A.pdf Integrative Illustration of a JCVI-syn3A Minimal Cell by David Goodsell (2022) which describes everything in the picture.en.bitcoin.it/wiki/Jercos mentions:www.bitcoinwhoswho.com/jercosinterview is the source. Persumably the contact was initiated via the private messaging feature of the Bitcoin Forum.
According to jercos the transaction was finalized over IRC chats. Jercos was 18 at the time of the transaction.

I-V curve of a diode
. Source. This image shows well how the diode is only an approximation of the ideal one way device. Notably, there is this non-ideal voltage drop across the device, which can be modelled as constant. It is however an exponential in fact.

- youtu.be/Fwj_d3uO5g8?t=514 applications:
- protection against accidental battery inversion
- rectifiers, notably mentions a diode bridge
I was trying to learn about how some types of quantum computers work, when I came across this pearl:
en.wikipedia.org/wiki/Wolfgang_Paul#Scientific_results Wolfgang Paul, 1989 Nobel Prize in Physics winner, referred to Wolfgang Pauli, 1945 winner, as his "imaginary part".
