Or only for the things that experience gravity as a curved surface? Gravity, arguably, does not experience gravity as a curved surface.

My guess... In the mathematics of the physics, gravity is a scalar field. We don't really know what gravity is, we just have various descriptions that seem to be useful at various …

Some thoughts... On the connected question of why human societies accelerated their development over time (recently posted on HN) a couple of comments are pertinent (see [0] and [1…

Efficient proprioception is useless if key behavioural incentives are misaligned with key aspects of the environment. Humans are quite good at creating collective organisations tha…

Imho, RRO only works well if some additional rules are added, to hold from the outset and throughout the process. As a prototype offering: 1. There must be sufficient representativ…

I agree with the comments that the article is misdirecting fluff. Cutting through... All organised systems (anything that we would describe as a system as opposed to random or chao…

An untested idea/suggestion... In the first Open Problem, maybe the generator tweak for random Hamiltonian paths is that two grids are needed: one for the eventual H-path; and one …

Maybe someone familiar with the graph theory math can help me. I don't understand why these properties aren't numerically accessible. Why is the estimation necessary? E.g. Assume N…

Why CO2 from air vs. extraction from seawater? I remember seeing some papers (e.g. [0]) suggesting the from seawater route was way more efficient per m^3 processed with a lot less …

I am not a lawyer, but... a public interest clause might not be the right tool, since public interest can be interpreted as restricted to information that would affect a person's v…

After constructing a better diagram that lens idea looks false too. Similar triangles win again.

A fair approach. Incidentally, I just drew some diagrams and with the assumptions that the Earth is not at the centre of expansion, Earth orbit has extremes (for parallax), and all…

I'm not a cosmologist but... Is it possible to have both photon tiring and expansion and still measure the same numbers in experiment? Also wouldn't the arc separation of deep fiel…

For the sake of HN archival history... The executive summary of my paper is that provably there are fatal inconsistencies in Cantor's Diagonal Argument (CDA). They take a few forms…

Lawvere's paper appears to suggest that if I refute one diagonal argument then I refute them all. Would you consider that to be an accurate description?

I'm not seeing this yet. Perhaps you could explain it to me in plain terms.

> Theorem: There is no bijection between ℕ and {0, 1}*. So no bijection between \bb{N} in an unspecified number base and some binary strings that could represent integers? That's a…

> Define a function z(n) = 1 - f(n)(n). I don't understand the notation f(n)(n). Is it related to f_{nn} in LaTeX notation? Your later text suggests maybe it was aiming at f(n,n) s…

The mileage of others may vary, but it has been my experience that there is no cogent solid proof of uncountability that can withstand concerted critique.[0] Being charitable one m…
