Back when NASA was flinging things into space for the first time, the tolerances that were even possible were extremely tight. Every pound mattered (every pound still matters, but because we have other things to do once we get to space nowadays, plus every pound is expensive). 600 pounds of white paint for the fuel tank was considered unnecessary, once the engineering team figured that it didn't actually protect the special foam covering of the fuel tank anyway. Thus the distinctive orange color! |

Fun fact: Columbia, pictured with the white tank, was the heaviest shuttle and was not modified to have the airlock necessary to dock with the ISS because the performance losses compared to the other shuttles made it difficult to use for ISS operations. |

Oh, I thought the pictures were backwards. The orange being the natural color and the white being paint is really critical information for it to make sense lol |

Its simple rocket math. Every lb of weight must consume fuel. Si.pky. 1 lb of weight needs 1 lb of fuel to escape orbit. But the fuel has weight also. So the effective fuel you need to lift the rocket and payload is exponential. The harder stuff is orbital mechanics. Getting things into orbit is easy. Having thwm go where you want is the hard part. |

It's always hillarious to me to see boomers on expensive bikes that aim to save every gram while they could save 20kg on themselves. |

The tyranny of the rocket equation. Generally, 1% of weight is payload, 85% is fuel. https://www.scientificamerican.com/blog/observations/escaping-the-tyranny-of-the-rocket-equation/ |

It's a competition between brand. They're at the point where decrease a single gram is incredible task and are all racing to become the lightest weight and aero-est bicycle and get to claim that. |

If you are trying to lose weight, you should be using the worst, heaviest bike possible. |

Well, it’s also fun to go places you know. If a shitty bike can only get you 20mi / 30km but a on a good one you feel confident doing a 30mi / 45km ride then the purchase makes sense. |

Well, not if you still want to have some fun while doing so. But I agree, that a regular bike should suffice and you don't need to worry about optimizing gear weight if you're not competing for anything and just ride it for your own well-being. |

And then you have E bike companies producing lead bricks that are non-functional without the motor doing 90% of the work. Or with the massive motorcycle seats that make pedaling actually impossible. |

Well, not necessarily. A bike that's got a full carbon frame also absorbs shock and vibration from the road better. This means you can ride longer distances without getting fatigued in places like your wrists or ass. Longer rides = more exercise. But once you have a carbon frame, chasing grams on other components gets to be a bit silly. |

You could also just walk whenever possible, burns more kcals/distance |

But didn't it have ejection seats at one point? |

That's less efficient time-wise though, since it takes significantly longer to walk the same distance compared to riding. Ie, riding 2 hours burns FAR more calories than walking for 2 hours. |

I've yet to ride a carbon frame for any amount of real distance, so idk how good they actually are. But having a less harsh ride can also be archived by not using the thinnest pizza cutter tires at 10 bar. Especially if we care about time ridden and not avg. speed. And it's going to be slightly harder to get the same speed out of comfy tires, so that's also more exercise. |
