Science: Everything explained by PV=nRT, F=ma=Gm(1)•m(2)/r^2

I have started a Technology thread to keep track of toys instead of ideas.

[Kepler]

Missed it by this much.

OK, you f-ckers. No cheating. Why?

My guess, without cheating: the chain links that hit the bottom exert an extra pulling force as they bounce around.

My first instinct was the dzhanibekov effect

edit: should have watched with it unmuted. What the ****.

I think that's halfway, unless I misunderstood what you meant.

I suspect if the steps fall perfectly flat and parallel to the earth, there's minimal effect. I also think the wider the platform, the more dramatic the effect.

I think the end of the step that hits the table converts the linear motion to rotational motion when it hits the table. That far end winds up being faster because it's opposite the pivot point (where the other end strikes the table) so its rotational speed is faster than gravity. It ends up pulling down each end, alternating between the two.

Here is a most excellent example of an artist playing with how the human brain works when looking at things.

Zoom in after giving it a look. It reminds me of newspaper cartoons from back in the day.

Ah, got it. Because the rings are angled, when the first end hits the table, it “instantly” starts to rotate, and when it does so, that exerts a net force on the knot in the rope attached to the end that is still falling. That force will be small, but over enough collisions, it’s enough to accelerate the ladder downward faster than the pure free-fall of the other ladder.

I had Professor Ruina for my basic statics class - this is a very “Ruina” demonstration. Very fascinating guy - saw him at all manner of campus events; he was one of those people who just enjoyed the **** out of leaning and it didn’t matter the subject.

Is the “trick” that the rungs are angled?

[Kepler]

Antimatter falls.

Yay science.

After a 2015 pilot release in the Colombian city of Bello, the researchers expanded their operations to the nearby cities of Medell?in and Itagua. Although researchers have conducted experiments like this across the world, these releases marked the program's largest yet.

By April 2022, they found that around 80% of all mosquitoes in Bello and Itagui had been infected by the Wolbachia mosquitoes (through cross-breeding), and around 60% in Medell?in.

To see whether this infiltration had actually impacted dengue levels in the three cities, the researchers evaluated the number of cases reported over the course of the releases until July 2022.

They found that the introduction of the infected mosquitoes into local mosquito populations was "associated with a significant reduction" in dengue of up to 97% in each city compared to ten years prior to the start of the experiment.

Antimatter having weight is really important, but saving lives via the reduction of dengue is a HUGE deal.

Well, except to the COVID deniers.

They're playin' God with mutant mosquitoes, don'tcha know. It ain't natural.

[Kepler]

Well holy sh-t.

The 1% of humanity that is smart almost makes up for the 50% that is rock stupid.
