Quantum Particles In Motion Can Still Travel Backwards (phys.org) 59
Quantum particles have a unique ability to travel in the opposite direction from their momentum. Or, as slew (Slashdot reader #2,918) puts it, "When pushed, quantum particles can fight back." slew writes:
Who knew quantum particles were passive aggressive? It's subtle, but researchers "have shown that 'backflow' can always occur, even if a force is acting on the quantum particle while it travels. The backflow effect is the result of wave-particle duality and the probabilistic nature of quantum mechanics..."
Dr Daniela Cadamuro, Researcher at the Technical University of Munich, said "The backflow effect in quantum mechanics has been known for quite a while, but it has always been discussed in regards to 'free' quantum particles, i.e., no external forces are acting on the particle."

There's some serious psychology behind some of the slashdot trolls.
There's the "always make a post and simply contradict" types, there's the "spread fake anecdotes about the poster" types, there's the "talk about the poster behind his back" types(*), and there's the "simply post an insult" types, there's "take the argument to a ridiculous extremes" types, and "associate the argument with racism/homophobia/whatever" types ("that argument is racist!").

I supposedly have 10+ user accounts to argue with myself.
They're using this particular tactic on you because their reading of your personality type indicates that it'll get you angry.
I'm not angry. I'm amused by this attention and the traffic it drives to my websites. If the trolls left me alone, I would have been gone months ago. Now that they proven the value of Slashdot, I'm here to stay and make my half-cents.

Back before leaking culture, AC used to be a valuable feature. Now five nines of AC posts are people who don't feel like logging in or trolls.
I guess the analytics shows they don't run adblockers. It's too bad Slash doesn't have cookie-based shadowban based on downmods though.

Well, maybe it's a side effect. You know, to an observer, traveling backwards in space may appear to be traveling forward in space as they travel backward in time. So the more you push against these articles, the more will appear. Moral of the story? Don't feed the time trolls :-)
Now where's my Tardis?

In any case as a tech site I would think Slashdot is a good fit for this. Imagine a backpropagation algorithm that utilizes time travel!
One of my favorite James P. Hogan novel was "Thrice Upon A Time" [amzn.to], where an engineer develops a computer that send email forward or backward in time. Whenever an email got send backward in time, it reset the timeline at the point where the email got received. The story got reset three times before the engineer decides to leave it alone.

Occasionally one comes across an interesting story and/or comments on here, but is increasingly rare as Slashdot circles the drain.
Back in the beginning, a link to my website got 3,000 clicks in a day

If it wasn't for the trolls keeping me amused, I would have left a long time ago.

It fascinates me, "quantum weirdness." I think it comes from quantum particles oscillating between a thin space and a thick space form. Thin space being space as we think of it, and thick space being what we call particles. When the thin-space collapses back to particle density it can do so at any point in the thin-space form probabilistically. Does the wave express this oscillation between densities? If the thin space collapses back to particle form on the other side of a barrier we would have "quantum tun
Quantum Mystery Cult? (Score:2)
I'm not disputing the science of this, but articles like this one are really just pushing the cult of the "Quantum Mystery". QM is difficult to understand intuitively, not because it is a deep mystery, but because it involves a lot of very hard mathematics - functional analysis, Hilbert- and Banach spaces, Lie theory and so on, not to mention measure theory and Lebesgue integrals; and that is before you even attempt to involve relativity in any form. Unfortunately this has led to the rise of a sort of Quant
