> it reads like Claude output
Yep. From the site's about page:
> This site is produced with substantial help from large language models: they assist with the literature search, the drafting, and the arithmetic.

> how much scrutiny did this get for accuracy?
The inclusion of references without hyperlinks suggests it wasn't thoroughly checked: they were probably put there by Claude, and as they aren't links the author probably hasn't read them (they could possibly have read them in hard-copy at a library, but given the rate at which articles were produced this seems very unlikely).
(One such reference is 17 - "Weijers, M. et al. “Heat-induced denaturation and aggregation of ovalbumin at neutral pH described by irreversible first-order kinetics.” Protein Science 12(12): 2693–2703, 2003")
FWIW, the author writes:
> " Ovalbumin coagulates irreversibly at 80°C (Weijers et al., 2003), permanently setting the foam structure.",
and the paper by Weijers et al. says:
> "A strong temperature dependence on the reaction rate was observed. At 80°C, half of the protein was denatured and aggregated in less than 2 min (half-time, th), while at 68.5°C this took approximately 6 h."
So, the citation is generally true-ish although a little bit imprecise.
At which temperature range Ovalbumin coagulates seems quite irrelevant for the whole article, however. To me it's unnecessary fluff, others might like that kind of detail.
(This does not imply anything regarding the article as a whole - it's just one thing I checked.)
Addendum:
> "Cast iron and carbon steel have nearly identical thermal conductivity (~52 W/m·K), which surprises most people."
is unsourced. And the precise "~52" is quite misleading - Wikipedia and online sources report thermal conductivities in the range of ~30-50¹.
Also:
> "Critically, whipped egg white foam drainage follows a hyperbolic saturation curve: v = V × t / (B + t), where V is the maximum drained volume and B is the drainage half-life (Lomakina & Mikova, 2006)."
As far as I can tell, the article² (cited twice for this claim) does not contain any equations modelling drainage over time, and especially not this equation or the term "hyperbolic".
So, it seems that you cannot really trust the sources the author's LLM included. For me, that means that I cannot trust any of the other claims in the article (or the author in general).

Similarly, the kite article [1] states that:
> The angle of attack, α, is the angle between the kite’s sail and the incoming wind. As α increases from zero, C_L increases approximately linearly until a critical angle (typically 12–18 degrees for flat surfaces), beyond which the airflow separates from the upper surface and the kite stalls (DT Online, 2024).
The supporting reference is [2]; this doesn't refer to a linear releationship or a critical angle, but does say that the angle of attack is typically 20 to 30 degrees (contradicting the claim that a kite would stall if the angle is above 12-18 degrees).
So I agree that this website does not seem trustworthy. Specific claims may or may not be correct, but they're not supported by the presented references.
