Does anyone know why does the footer of the page have a “ssn”?

#13Chicken sized 74C object radiates at 2kW? Probably cools rather fast, but still feels like high number... Energy in general really feels weird, when you look at the numbers. Like potential energy or kinetic on relatively low speeds... And then compared to chemical energy... Edit: Also how do you get it there? Wouldn't you need to hit it with higher frequency to start with to get to temp?
Your intuition is right in this case. A 2kW oven is more than enough to heat small chicken up to temperature. The author lazily took the 165F temperature and put it into a blackbody calculator without converting the units. Anything but the metric system...
Assuming the chicken has a surface area A=1m^2 (corresponding to a perfectly spherical chicken of radius=25cm/diameter=50cm, a little bigger than usual) and is a perfect blackbody (just going to handwave this one).
with the incorrect temperature: A blackbody with T=165°C (438 K) and A=1m^2 radiates P=2090 W.
with the correct temperature: A blackbody with T=74°C (347 K) and A=1m^2 radiates P=824 W.
Also neglected is the incoming radiation from the ambient environment. Without this, the "power loss" is closer to measuring the chicken in deep interstellar space. from a room temperature environment: T=20°C (293 K) and A=1m^2 radiates P=419 W onto the chicken.
The net power loss of the cooling chicken on the kitchen counter is therefore something like 824-419 = 405W, rapidly decreasing as the temperature drops towards room temperature. e.g. at 50°C it's around 200W.

It's just the digits of pi, likely not their real SSN.

"a little bigger": it would weigh 65 kg.

points for'a perfectly spherical chicken'.

#17Are we assuming perfectly spherical chickens in vacuum?

Yeah, lets go with that

#19Chicken Gun: https://en.wikipedia.org/wiki/Chicken_gun I’m pretty sure NASA used a version of this to test the resiliency of the space shuttle tiles. Not fast enough to cook tho.
Could aim it at the space station. Would be nice to receive a fresh cooked chicken in orbit I imagine.

#20OT, but the site of that author looks very interesting in general: https://james-simon.github.io
