Linear polarization holography
In conventional holography, the hologram is formed by recording the interference fringes of two coherent beams using a photosensitive material. The amplitude and phase information of the original signal wave can be reconstructed correctly when readin.....»»
Turning any camera into a polarization camera
Polarization, the direction in which light vibrates, provides a lot of information about the objects with which it interacts, from aerosols in the atmosphere to the magnetic field of stars. However, because this quality of light is invisible to hum.....»»
Frequency-dependent polarization of repeating fast radio bursts reveals their origin
Fast radio bursts (FRBs) are the brightest millisecond-duration astronomical transients in radio bands with a yet unknown origin......»»
What Is A Linear Foot | Architect’s Information
Have you recently found out about the linear foot measurement? If yes, don’t worry, we’ve got your back. One of the most common problems seen in hardware stores is that people aren’t aware of the right unit of measurement. And, in suc.....»»
Inside Finland"s Plan To End All Waste by 2050
An anonymous reader shares a report: As natural resources diminish and the climate crisis grows more acute, the notion of a circular economy has been gaining traction around the globe. Most modern economies are linear -- they rest on a "take, make, w.....»»
Swedish tweets about immigration reveal new insights into polarization dynamics
A computational analysis of more than 1 million Tweets from Swedish speakers has found little evidence for significant polarization within this network on the topic of immigration—even after Sweden's 2015 refugee crisis. Elizaveta Kopacheva and Vic.....»»

Metalenz unveils PolarEyes sensors that are 1,000 times smaller than a human hair
Metalenz unveiled a new kind of sensor which uses polarization technology to bring a new kind of sensing to camera-equipped devices. Metalenz unveiled a new kind of sensor which uses polarization technology to bring a new kind of sensing to camer.....»»
3D digital holograms on smartphones
3D holograms, previously seen only in science fiction movies, may soon make their way to consumer technology. Until now, 3D holograms based on phase shifting holography method could be captured using a large, specialized camera with a polarizing filt.....»»
Cylindrical vector beam multiplexer/demultiplexer using off-axis polarization control
Cylindrical vector beam (CVB) multiplexing has emerged as a powerful technique to boost signal channels. Coupling and separating CVBs are two pivotal elements in CVB multiplexing communication. Although off-axis control technologies such as miniature.....»»
The future of 3D display and the emergence of holographic television
The pioneers of holography (Gabor, Leith, Upatnieks, and Denisyuk) predicted very early that the ultimate 3D display will be based on this technique. This conviction was rooted in the fact that holography is the only approach that can render all opti.....»»
Polarization, diversity, and democratic robustness
Polarization is dangerous for democracy. Though the U.S. Constitution was designed to harness rivalry with a diverse, redundant, and modular set of institutions, if that rivalry curdles into the belief that your competitors are your enemies, those in.....»»
The emergence and perils of polarization
We can't understand polarization unless we analyze it as a complex system, argue SFI External Professor Scott Page (University of Michigan) and co-author Delia Baldassarri in a commentary for a special feature on the dynamics of political polarizatio.....»»
Halo Infinite’s open world doesn’t hold up to past linear campaigns
Without set pieces that players can easily memorize, Halo Infinite's open-world campaign just seems forgettable......»»
Will Political Polarization Stop US Lawmakers from Regulating Big Tech?
A media lobbying group wants to see tech platforms reigned in with stronger antitrust laws. But the group's president tells the New York Times the biggest force supporting the status quo is hyperpartisanship. The Times reports: The lack of regulati.....»»
The Witcher Season 2 review: Moving forward again, with focus
After a successful but convoluted first season, The Witcher brings Henry Cavill's monster hunter back for a more linear, and rewarding, second story arc......»»
Paramount+ adds Live Channels for ‘effortless’ entertainment

Preventing extreme polarization of political attitudes
Encouraging interactions between people on opposite ends of the political spectrum may not be the best way to foster tolerance in a polarized nation......»»
The tipping point for legislative polarization
A predictive model of a polarized group, similar to the current U.S. Senate, demonstrates that when an outside threat—like war or a pandemic—fails to unite the group, the divide may be irreversible through democratic means. Published in the Proce.....»»
People unknowingly group themselves together online, fueling political polarization across the US
As people curate their online news feeds, they may be unwillingly sorting themselves into polarized networks, according to a study led by researchers at Princeton University......»»
