Author is probably Australian, I would use the same words.
Just checked linkedIn, yep they are from NSW.
How did you manage meaningful attitude control with only torque rods? They would need to big (read: heavy) to be useful — was this just stabilising in inertial frame or active pointing?
Mag dipoles in chassis and components tend to lock tumbling satellites into the Earth’s magnetic field. Did you see this? Or did you see atmospheric drag dominate at this altitude?
If you’ve read the book, they stressed many times that this was irrelevant to the model and also probably untrue
Hmmm.
> the listening circuit must also be tuned to resonate at the expected frequency of proton precession, which will depend on Earth’s magnetic field at your location
> the frequency of these tones matches the magnetic field at my location to about 1 percent
I don’t doubt the physics, but I’m not sure about the experiment design. Being able to hear the correct frequency may just mean you’ve built an oscillator and tuned it.
I think the URL is telling
Sorry for snooping—if this is about Foxtel, they were also sold to a UK company this year right?
I guess you’d expect some staff turnover, but not mass layoffs.
Honestly par for the course for human treatment of chickens. See chick culling [1]. Billions of baby chicks are macerated live because they are not commercially useful.
> Worldwide: As of 2015, approximately 7 billion male chicks were culled annually around the world

Not really, this is still a point of debate among vegan communities. Many of us have no moral issue with food grown using animal-derived biotech, as this does not require animal agriculture at all
1. Observations of genetic drift and biodiversity are consistent with our model of evolution at every scale. This model is the best fit to the data regardless of politics and media
2. Our ability to replicate something gives zero information on its origin. I’m not sure I understand the algorithm comment
3. Sure, GP simplified a bit too much there. Your comment is consistent with modern models of evolution. Each genome has a pool of random variations, which may or may not be expressed in an organism. Each organism is a test of those gene expressions.
A genome changes over time when an organism passes this test (e.g. reproduces), increasing the expression of its genes across the population. This occurs in parallel for many possible variations.

Ah, I should have read the rest of your comment first, but I’ll leave this here anyway. I don’t think your explanation is valid— we are biologically and socially primed for religious ideology, but its use as a world model is very limited.
We will eventually find answers to these questions, as the ratchet of scientific progress clicks along. Religion has never been useful in the same way
(Non-consensual sacrifices)
The article is proposing the latter. Low AVP could contribute to symptoms of ASD. If this is true, they expect a positive correlation between ASD and other better-known issues caused by low AVP.
Nice to see some Adelaide representation! I’ve had the pleasure of working with these guys— we have a Neumann thruster on one of our satellites. Very cool technology and great team.
Did you mean to leave in the ChatGPT preamble?
This might be the case now but shouldn’t be a particularly useful distinction for very long— on the grand scale of intelligence, the difference between the smartest human and the average human is tiny.
> The next time somebody claims that the human brain operates according to bayesian logic, simply ask them what prior probability they (currently, until the next update) would assign to that claim.
A = a person is able to (correctly or not) quantify their priors
B = brain operates according to Bayesian logic
P( A ) ≈ P( A | B )

Being part of specific cultures and communities definitely does though
