Most of us natively write anti-clickbait titles.
Though it is rarely cited, my favorite paper that I've co-authored is:
Indirect Evidence for Lévy Walks in Squeeze Film Damping: https://arxiv.org/abs/1005.4926 https://arxiv.org/abs/1005.4926
It could have alternatively been titled: "Holy crap! Did you know that high-vacuum gas particles trapped between two walls follow fractal paths?!"
- ChuckMcM 8y ago"You won't believe where these high vacuum particles go when they move, or how they get there!"
- mromanuk 8y ago“The walls hate these particles, they can move in fractal ways, you can learn the secret, too”
- kevin_thibedeau 8y agoBait me with how this affects my car insurance and you've got a click.
- jonbarker 8y agoThese four tech giants are upending this centuries old industry... with quantum entanglement.
- jonbarker 8y agoA light wave got sucked into a black hole, you won't believe what happened next! I predict a new meme theme of taboola/outbrain style headlines that are actually semi-accurate sciencey clickbait titles. Genius!

- phaedrus 8y agoI wonder if this in any way related to (causes, or shares a cause with) Mandelbrot's discovery that electrical noise on a signal line follows a Cantor set pattern? Or perhaps the motion of the particle is due to the Heisenberg uncertainty principle? (If the exact position and velocity of a particle is not knowable in detail, then its path would have to have a fractal dimension overall.)
- ISL 8y agoThere's unlikely to be any direct link. The Levy-walk behavior is a simple consequence of geometry interacting with the distribution of particle directions that a particle might select each time it comes off the wall. The result turns out to be scale-invariant, and was a surprise for us, as we had expected a nice integer power-law in the scaling of the gas dynamics, and it turned out to be fractional. The upshot is that when computing gas damping in high-precision force/displacement sensors, one must resort to numerical simulation. One consequence of this work, in concert with the groups at Trento and MIT is that the LIGO gravitational-wave detectors opened up their gaps between the detector masses and nearby "reaction masses". The easy gaps to open happened before Advanced LIGO turned on, and I believe that the more difficult/expensive gaps to open are being upgraded roughly now. It's fun how little table-top measurements on the minutiae of force-sensing can have impacts on whether or not we observe cataclysms billions of light-years away....
