  • It’s more about a minimum of weight or pressure that affects it. So the higher the pressure the more likely it is to flex the road where a small vehicle with light pressure might not make it flex at all. The heavier it is the more the weight will flex the subsurface and cause more damage.

    “To give you an example of that impact, let’s do a quick calculation. Here in New Zealand, the heaviest vehicle allowed on (some of) our roads is the 50MAX truck. It has nine axles and a total weight of 50 tonnes, so the load-per-axle is 5.55 tonnes. The best-selling car in NZ in 2022 was the Mitsubishi Outlander. It weighs 1.76 tonnes, so its load-per axle is 0.88 tonnes. The fourth-power law says that to calculate the relative stress that these two vehicles apply to a road, you take the ratio of their loads-per-axle and raise the result to the fourth power. In this case, (5.55 / 0.88)4 = 1582. In practical terms, it means that a 50MAX truck applies as much stress to a road as 1,582 cars (or quite literally billions of bicycles)”

    The sad part is that there isn’t any real answer, like a lot of fundamental things in science we don’t really know how it works and won’t for decades. My personal theory is more along the lines of the whole tearing muscles concept is crap and exercise is basically just a signal for your body to make more muscle and doesn’t directly cause anything.

    That’s not a biochemist, memorizing the amino acids is literally biochem 1 on college. Most people with a biology undergrad take that.

    Being a biochemist is more about understanding the whole system of how proteins interact, and not really about memorization of any specific protein.
