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?

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.

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

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 )
