Submission + - Objective Reality May Not Exist at All, Quantum Physicists Say (popularmechanics.com)

Submitted by waspleg
waspleg writes: “We used nuclear magnetic resonance techniques similar to those used in medical imaging,” Roberto M. Serra, a quantum information science and technology researcher at UFABC, who led the experiment, tells Popular Mechanics. Particles like protons, neutrons, and electrons all have a nuclear spin, which is a magnetic property analogous to the orientation of a needle in a compass. “We manipulated these nuclear spins of different atoms in a molecule employing a type of electromagnetic radiation. In this setup, we created a new interference device for a proton nuclear spin to investigate its wave and particle reality in the quantum realm,” Serra explains.

“This new arrangement produced exactly the same observed statistics as previous quantum delayed-choice experiments,” Pedro Ruas Dieguez, now a postdoctoral research fellow at the International Centre for Theory of Quantum Technologies (ICTQT) in Poland, who was part of the study, tells Popular Mechanics. “However, in the new configuration, we were able to connect the result of the experiment with the way waves and particles behave in a way that verifies Bohr’s complementarity principle,” Dieguez continues.

The main takeaway from the April 2022 study is that physical reality in the quantum world is made of mutually exclusive entities that, nonetheless, do not contradict but complete each other.

Submission + - We're All Being Judged By A Secret 'Trustworthiness' Score (wsj.com)

schwit1 writes: Nearly everything we buy, how we buy, and where we're buying from is secretly fed into AI-powered verification services that help companies guard against credit-card and other forms of fraud, according to the Wall Street Journal .

More than 16,000 signals are analyzed by a service called Sift, which generates a "Sift score" ranging from 1 100. The score is used to flag devices, credit cards and accounts that a vendor may want to block based on a person or entity's overall "trustworthiness" score, according to a company spokeswoman.

From the Sift website: "Each time we get an event be it a page view or an API event we extract features related to those events and compute the Sift Score. These features are then weighed based on fraud we've seen both on your site and within our global network, and determine a user's Score. There are features that can negatively impact a Score as well as ones which have a positive impact."

The system is similar to a credit score except there's no way to find out your own Sift score

Factors which contribute to one's Sift score (per the WSJ):
  • Is the account new?
  • Are there are a lot of digits at the end of an email address?
  • Is the transaction coming from an IP address that’s unusual for your account?
  • Is the transaction coming from a region where there are a lot of hackers, such as China, Russia or Eastern Europe?
  • Is the transaction coming from an anonymization network?
  • Is the transaction happening at an odd time of day?
  • Has the credit card being used had chargebacks associated with it?
  • Is the browser different from what you typically use?
  • Is the device different from what you typically use?
  • Is the cadence of the way you typed out your password typical for you? (tracked by some advanced systems)

BioShock Backlash 163

Posted by Zonk from the whap-ow dept.
Via Rock, Paper, Shotgun, a Kieron Gillen piece at Eurogamer about the heavy backlash from PC gamers against BioShock . Gillen tackles all of the most common complaints, including favorites like 'it's too easy,' and 'the ending stinks.' "BioShock is both a more accessible and easier game than System Shock 2. But 'easier' doesn't have anything to with it being 'dumber,' and hating 'more accessible' is just petty elitism from people who'd actually like videogames to be a ghetto consisting of them — especially when some of the things to make the game more accessible can be turned off. As long as point two's not true, then the former really doesn't matter."
