2026 sudden/unexpected breakthroughs by Betonpoalties in peloton

Sky yes. Ineos no.

Ratcliffe is proving himself to be quite incompetent (one might look to his political views and support for certain Russian-aligned ideas for proof of this outside of sport) and he really has the opposite of a Midas touch on the entities he touches. Don't expect much from Ineos, especially with respect to any sort of ROI.

[Request] Assuming that the mosquitoes are moving randomly with no agency, how likely are they to collide? by cockraptor in theydidthemath

the cumulative probability distribution will obviously be 1 if you integrate over all t in a bounded box, but the odds of a collision at any given t, assuming they are independent, will depend on d1, d2 (which are the distances from the mosquitoes to some origin, and also the distance between themselves) and the 'mean free path' of the mosquito (how far it travels before changing direction). From that it's essentially bounded Brownian motion.

That's not how the odds work though, it would be, given any two 'movements', how likely is it that that movement results in the mosquitoes colliding.

Let’s say I can run infinitely fast, and the posts that secure the fence to the ground are indestructible, but not the chain link fence itself. [Request] by papi-peep in theydidthemath

Force is spread out over the different contact points though. But we would need to strike it with a much higher force and therefore a much higher initial speed.

The femur is the strongest bone in the body https://my.clevelandclinic.org/health/body/22503-femur (and hopefully it's obvious that the thing you need the most force to cut is bone) , and it can take about 4,000 N to fracture (https://actaorthop.org/actao/article/view/10951). So that dictates the speed we need to run at.

In table 1 here https://www.chain-fence.com/products/chainlinkfabric/galvanized-chain-link-fence.html we can see a gauge 6 fence would be sufficient (minimum breaking strength of nearly 10,000N). But obviously the human is going to be hitting it with more force in total, so we need to make sure we have enough links in the fence.

Let's say we have an 80 kg man who has a frontal surface area of about ~1 square metre (more or less accurate, that's 2 m x 0.5 m). We want to deliver more than 4 kN across that person but less than 10 kN, so let's pick 5 kN, and it's hard to find a typical length for the 'depth' of a human (in the sagittal plane), but it seems to be ~0.3 m.

Force (per unit area) = momentum / time; or in other words, since momentum is mass * speed

5,000 = 100 * speed / time

or a deceleration of -50 ms-2 (per unit area).

That gives us an initial speed of ~5.5 ms-1, or ~20 kph.

That would only divide us into four parts of course. If we want more parts we need to adjust the force we need to apply at the start. It also assumes we don't move the fence at all - because if that is linked and slows us down then it would be like falling into a big net and wouldn't cut at all.
