I thought the FDA guideline was once the internal temperature reaches 160 or 165 or something it didn't need to sustain that temperature? it was only the lower temperatures that required some duration to achieve the same log reduction as reaching 160/165?
Chicken 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?
Spiritual successor of this is how many slap's it take's to cook a chicken. There was a viral video on this a few year's ago rather funny https://www.youtube.com/watch?v=LHFhnnTWMgI
I love that when I opened this article i already knew some elements, from having read it months ago on HN
So now I will remember it a bit better and for longer
Hackernews is actually like Anki cards for nerd (and in this case useless) Internet stuff
Assuming an infinitely malleable chicken...
This reminds me of the old blacksmithing trick: https://www.youtube.com/watch?v=4I68Cik7ywg
That chicken would be obliterated long before cooking
If we're considering unconventional cooking methods, what about orbital re-entry cooking, or atmospheric friction cooking in general? What speed/altitude would a plane need to be travelling at to lob a chicken out the window and have it perfectly cooked when it hit land?
SR-71 external temp reached 600F or so at Mach-3, so that might result in a charred chicken.
I still need to know how fast I need to ride my bike to not freeze my hands, when biking during the winter without mittens. There has to be some sweet spot where my hands a warm, but not burning.
This is exactly why I like hanging out with math & physics types. It has big "assuming a spherical, frictionless horse" energy.

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.
Someone did build himself a chicken slapper to he could slap himself some chicken dinner: https://www.youtube.com/watch?v=LHFhnnTWMgI
"Mom, where are the hitters in the oven?"
"We call them heaters in that one case."
OT, but the site of that author looks very interesting in general: https://james-simon.github.io
And the experimental evidence…
"Assume a spherical chicken..."
Sounds more like a recipe for chicken soup ...
The question posed is not "how hard" but "how many times and how hard". You can't cook a chicken in one hit because that amount of heat requires a large amount of force which then obliterates the chicken. There's a video on youtube that tries to answer this question.
I don’t think I agree with the assertion that instantly bringing the chicken up to temp wouldn’t result in it being cooked. Especially since the classic solution got the chicken up to 400F. I don’t care how fast it cools off, if we assume magic uniform heat distribution from the slap, starting at 400 F, all the proteins are gonna be denatured and the diseases killed.
Used to joke in the kitchen that I worked in that if we were pressed for time, instead of baking something for an hour at 300°, we can just bake it for 6 minutes at 3,000°. It's such a fun concept and always makes me giggle
"if you slap a chicken at 3726 mph, it will be cooked."
Certainly holds true for the Gen Z sense of the word.
I raise the bar higher - how hard and how long do you need to hit the chicken to make it sous vide
Incredible. Was not expecting an answer that felt reachable.
Does anyone know why does the footer of the page have a “ssn”?
Are we assuming perfectly spherical chickens in vacuum?
I thought this was xkcd's What If? series from the title.
By the way, it's got a Youtube channel now and it's as good as ever: https://www.youtube.com/@xkcd_whatif
Motion is relative, so firing a chicken at a static target is also a possibility.
The trouble would be imparting and spreading enough energy through the entire mass uniformly enough to have something remain.
It likely wouldn't work in the real world because the result would obliterate bones resulting in something worse than Chicken McNuggets, and not cook it sufficiently long to be safe from bacterial contamination.
If attempting such a feat, it would generate visible light. There's a good chance of generating some long-wave UV at the energies involved (several MJ, which would be a chicken flying at about 2 km/s. It would instantly disintegrate.)
Conspicuously, this is from June 2020
is it cooked or vaporized?
You don’t have to hit a chicken hard to cook it you just shoot it at a wall.
This is really disgusting. Chickens are feeling animals as well.
Sora, show me this.
I assumed the question was how to achieve the proper preconditions for cooking a chicken while avoiding any animal cruelty charges.
Clearly, we could simply knock its head off with a bat, since today I learned you can physically cook chickens with bats and professional batters, via a method well suited to humanity's eminent migration to outer space.
But I expect with some years of strength training and finesse, a very hard flick to the back of the chicken's lower noggin could dislodge the first cervical vertebrate from the skull, severing the spinal cord's integration with the brain stem.
Whether actually dead, or merely in a persistent vegetative state, the chicken may now be cooked.
However, if the chicken is merely headless [0], but in good health, one should not cook it.
