09/27/2024 NIST's new recommendation on passwords:
https://pages.nist.gov/800-63-4/sp800-63b.html#passwordver
"1. Verifiers and CSPs SHALL require passwords to be a
minimum of eight characters in length and SHOULD require
passwords to be a minimum of 15 characters in length.
2. Verifiers and CSPs SHOULD permit a maximum password
length of at least 64 characters.
3. Verifiers and CSPs SHOULD accept all printing ASCII
[RFC20] characters and the space character in passwords.
4. Verifiers and CSPs SHOULD accept Unicode [ISO/ISC 10646]
characters in passwords. Each Unicode code point SHALL
be counted as a single character when evaluating
password length.
5. Verifiers and CSPs SHALL NOT impose other composition
rules (e.g., requiring mixtures of different character
types) for passwords.
6. Verifiers and CSPs SHALL NOT require users to change
passwords periodically. However, verifiers SHALL force a
change if there is evidence of compromise of the
authenticator.
7. Verifiers and CSPs SHALL NOT permit the subscriber to
store a hint that is accessible to an unauthenticated
claimant.
8. Verifiers and CSPs SHALL NOT prompt subscribers to use
knowledge-based authentication (KBA) (e.g., "What was
the name of your first pet?") or security questions when
choosing passwords.
9. Verifiers SHALL verify the entire submitted password
(i.e., not truncate it)."

is okay, but it was probably also glass or ceramic and more
breakable.
09/26/2024 Estimating the size of a olive oil molecule:
https://www.atomsonly.news/p/franklin-oil
"Rayleigh carefully measured a tiny volume of olive oil -
0.81 milligrams, to be exact - and placed it onto a known
area of water. The oil quickly spread out and covered an
area, which Rayleigh precisely measured. And then he ...
divided the volume of the oil by the area it covered, thus
estimating the thickness of the oil film. Assuming that the
oil formed a single layer of molecules - a monolayer - then
the thickness of the oil film is the same thing as the
length of one oil molecule."

09/26/2024 eVinci nuclear microreactor:
https://newatlas.com/energy/evinci-nuclear-microreactor/
"[Westinghouse's] eVinci microreactor, [] is less than 10 ft
(3 m) in diameter and generates up to 5 megawatt electrical
(MWe) with a 15 megawatt thermal (MWth) core design.
...
[I]t has no moving parts once in normal operation and
requires no water or other coolant circulation. It uses
highly robust TRISO (TRi-structural ISOtropic) fuel, which
consists of uranium enriched to 19.75%, sealed into pellets
the size of millet seeds made of uranium, carbon, and
ceramic. These pellets are combined into small spheres that
are then packed into rods and inserted into the core. The
result is a fuel assembly that is extremely durable,
resistant to heat and corrosion, and produces a
self-limiting nuclear reaction that cannot go out of
control.
...
Instead of circulating water, air, helium, or molten salts,
the reactor uses a solid-steel monolith to house the core
and absorb heat. From there, alkali heat pipes passively
conduct the heat away using phase changes in the alkali
metal to cool the reactor and convert the heat into
electricity.
The result is a compact, inherently safe design."

https://science.nasa.gov/blog/a-striped-surprise/
"The [Perseverance] science team thinks that this [black and
white striped] rock [which they have named 'Freya Castle']
has a texture unlike any seen in Jezero Crater before, and
perhaps all of Mars. [Their] knowledge of its chemical
composition is limited, but early interpretations are that
igneous and/or metamorphic processes could have created its
stripes. Since Freya Castle is a loose stone that is
clearly different from the underlying bedrock, it [] likely
arrived [] from someplace else, perhaps having rolled
downhill from a source higher up. This possibility has [the
science team] excited, and [they] hope that as [they]
continue to drive uphill, Perseverance will encounter an
outcrop of this new rock type so that more detailed
measurements can be acquired."

2. Quit the app
3. Set the system date far into the future (say April 5,
2063)
4. Open the app and trigger the prompt
5. Click "Allow for One Month"
6. Restore the correct date
See also: https://lapcatsoftware.com/articles/2024/8/10.html
1. To stop the prompts set the date to far in the future
for a particular app:
$ defaults write ~/Library/Group\ Containers/group.com.apple.replayd/ScreenCaptureApprovals.plist "[Application Full Path]" -date "3024-09-21 12:40:36 +0000"

09/18/2024 CMS confirms prior measurements of the W boson's mass:
https://home.cern/news/press-release/physics/cms-experiment-cern-weighs-w-boson-mass
1. The Standard Model predicts that the W boson's mass is
"80353 million electronvolts (MeV) within an uncertainty
of 6 MeV"
2. In 2022, the Collider Detector at Fermilab (CDF)
measured the W boson's mass as "80433.5 MeV with an
uncertainty of 9.4 MeV, [which] differed significantly
from the Standard Model prediction and from [] other
experimental results"
3. In 2023, CERN's ATLAS Collaboration measured the W
boson's mass as "80366.5 MeV with an uncertainty of
15.9 MeV, [which] lined up with all previous measurements
except the CDF measurement"
4. CERN's CMS experiment has now measured the W boson's mass
as "80360.2 [MeV] with an uncertainty of 9.9 MeV, [with]
a precision comparable to that of the CDF measurement and
[] in line with all previous measurements"
SM continues to hold.

09/18/2024 Proposed experiment to confirm QED photon scattering:
https://physics.aps.org/articles/v17/s109
"A long-standing prediction of quantum electrodynamics is
that high-energy photons can scatter off each other.
However, this process has yet to be observed because
dedicated experiments have an extremely low signal-to-noise
ratio. Now [researchers] ... have designed an experiment
that could achieve a high-enough signal-to-noise ratio to
measure the phenomenon[.
...
[The researchers] propose colliding three laser beams: an
x-ray beam and two high-power optical beams. The two optical
beams provide the photons that scatter off each other, and
the x-ray beam imparts a momentum kick to the scattered
photons. This kick alters the trajectory of the photons and
spatially separates them from much of the experimental
background ... [increasing] the signal-to-noise ratio."

"[T]he researchers assigned the [study's] participants, who

of roughly equal size. The smartphone group reduced their
private smartphone use by one hour a day for one week. The
sport group increased their daily physical activity by 30
minutes. The combination group did both, and the control
group didn't change their routine at all.
...
In the smartphone group and the combination group, the
researchers found that work satisfaction and motivation,
work-life balance and mental health had improved
significantly. What's more, the feeling of work overload and
symptoms of problematic smartphone use were significantly
reduced. All interventions led to a reduction in depressive
symptoms and they increased the participants' sense of
control."

"The Hubble Space Telescope and the Chandra X-ray

waltzing around each other. ... They are approximately 300
light-years apart - the closest AGN [Active Galactic
Nucleus] pair seen in visible-light and X-ray wavelengths.
...
The two supermassive black holes were once at the core of
their respective host galaxies. A merger between the
galaxies brought the black holes into close proximity. They
will continue to spiral closer together until they
eventually merge - in perhaps 100 million years - rattling
the fabric of space and time as gravitational waves."

"Physicists from the Cavendish Laboratory in Cambridge have
created the first two-dimensional version of the Bose glass,
a novel phase of matter that ... has some glassy properties
and within it all particles are localized. This means that
each particle in the system sticks to itself, not mixing
with its neighbors.
...
To create this new phase of matter, the group overlapped
several laser beams to create a quasiperiodic pattern, a
pattern that is long-range ordered like a conventional
crystal, but not periodic, meaning that, like a Penrose
tiling, it never repeats. When filling the resulting
structure with ultracold atoms, cooled to nanokelvin
temperatures ... close to absolute zero, the atoms formed
the Bose glass."
