آشکارسازی الگوهای پنهان اسپینی: چگونه لیزرها قفل جهان کوانتومی را باز میکنند؟
مدتهاست که دانشمندان در تلاش بودند تا راههایی برای مطالعه نوع خاصی از امواج نوری به نام امواج پلاسمونیک ابداع کنند؛ امواجی از نوسانات الکترونی که وقتی نور با فلز برهمکنش میکند، در امتداد سطح فلزات حرکت میکنند. امواج پلاسمونیک میتوانند نور را در فضاهای کوچک متمرکز کنند و پلی بین نور و جهان نانو…

Although some channels have been removed, the curation process is considered opaque and insufficient by analysts. Given the pro-privacy stance of the platform, it’s taken as a given that it’ll be used for a number of reasons, not all of them good. And Telegram has been attached to a fair few scandals related to terrorism, sexual exploitation and crime. Back in 2015, Vox described Telegram as “ISIS’ app of choice,” saying that the platform’s real use is the ability to use channels to distribute material to large groups at once. Telegram has acted to remove public channels affiliated with terrorism, but Pavel Durov reiterated that he had no business snooping on private conversations. "There are a lot of things that Telegram could have been doing this whole time. And they know exactly what they are and they've chosen not to do them. That's why I don't trust them," she said. Perpetrators of these scams will create a public group on Telegram to promote these investment packages that are usually accompanied by fake testimonies and sometimes advertised as being Shariah-compliant. Interested investors will be asked to directly message the representatives to begin investing in the various investment packages offered. Groups are also not fully encrypted, end-to-end. This includes private groups. Private groups cannot be seen by other Telegram users, but Telegram itself can see the groups and all of the communications that you have in them. All of the same risks and warnings about channels can be applied to groups.
