Darthemed posted:Ripley's That factoid about the human body and the Sun angers me. There are a lot of ways to phrase and answer it so that is true (such as this). "Pound for pound, a human being actually generates more energy than the Sun!" is not one of them. To keep things simple, one pound of Sun can be assumed to be one pound of hydrogen atoms. Four hydrogen atoms go into the p-p fusion chain that produces 26.22 MeV of energy at the end of it. 1 lb. is 0.453592 kg, which is ~453.592 mols of hydrogen, which is divided by four for the stoichiometry of the reaction to give 113.2847 mols of hydrogen which means there are 6.82 x 1025 fusion reactions in a pound of the Sun. This gives off 1.79 x 1027 MeV of energy, which converts to 2.86 x 1014 J of energy. Using myself for the human, my basal metabolic rate is around 1979 food calories per day--meaning how much energy my body generates per day on average. Per pound that is 9.00 food calories, which is 37,000 J. The sun produces 286,000,000,000,000 J per pound--in a few fractions of a second. The human body over an entire day produces around 37,000 J per pound. Do not believe Ripley's Believe it Or Not, it's full of poo poo. (I grant you this is a Post-It Note calculation I did on my lunch break.)

Eh, most of the sun isn't actively fusing. 3.85e26 W with a mass of 2e30kg isn't a great ratio in energy:mass. A human body is about 100 W:70 kg, so significantly better. edit - It depends on if you mean the pound being the mass being "used", or the mass of the object in question.

goatface posted:Eh, most of the sun isn't actively fusing. 3.85e26 W with a mass of 2e30kg isn't a great ratio in energy:mass. Yeah, but one of the issues with the factoid in that Ripley's is that the Sun has structure. It isn't just a homogenous mass of incadescent gas where hydrogen is fused into helium, the fusion takes place in the core. That 3.85e26 W (joules per second) the Sun generates specifically comes from 1,370,000,000,000 pounds of hydrogen fused per second. So based on that you have an efficiency of 2.81e14 W per pound. Which again comes back to the Sun, pound for pound, pumping out ludicrous amounts of energy compared to the human body giving off 0.64 W per pound. So yeah, it depends on if you mean the pound being the mass used or just the mass of the object in question. It's a question with a lot of very interesting answers, which is why Ripley's just tossing out the question is so lame past getting people to discuss whether they're right or not. e: Hey cool, I got 2.86e14 J/s*lb in my first response and 2.81e14 J/s*lb in my second response. I just validated my method, and that is being a good scientist! LtStorm fucked around with this message at 23:24 on May 30, 2014 |

I wouldn't be surprised if it's been parroted around a lot by physics outreach people. It's one of those things like the old one of saying Saturn would float in a bath. You want to grab people's attention and make them go "What? That can't be right, that's dumb" in the hope they go and look it up. A chunk of the comics page is too small to go into the details of stuff like nuclear fusion, but might be big enough to make someone go and learn something about just how stupidly large the sun is. They might even learn enough to have an intuitive understanding in situations with cubic vs square growth! We can dream.

It's obviously the mass of the entire object in question - the objects being compared are 'the human body' and 'the sun'. If it were comparing the human stomach or the average human meal against the sun's fuel you'd have a valid nitpick.
