This is not because of any wizard. But, it is\npossible because of science which is creating magic. A team of researchers at\nthe \u201cMassachusetts Institute of Technology\u201d and \u201cGeorgia Tech\u201d are working on a\nsystem that is capable of reading pages of books without even opening them.<\/strong><\/p>\n\n\n\n<p><strong>MIT <\/strong>research scientist <strong>Barmak Hesmat<\/strong> quoted in a news report that<strong> Metropolitan Museum<\/strong> would allow this system to read some of the antique and fragile books. This system is not just the latest e-reader, but Museum understands the delicacy of these books and they are confident about this amazing system.<\/p>\n\n\n\n<figure class=\"wp-block-embed-youtube wp-block-embed is-type-video is-provider-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<div class=\"jeg_video_container jeg_video_content\"><iframe loading=\"lazy\" title=\"Reading through closed books\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/6i25SuJzb0A?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/div>\n<\/div><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>What\nis the technology behind this camera?<\/strong><\/h2>\n\n\n\n<p>To see through the books,<strong> terahertz radiation<\/strong> is required, this is a band of <strong>electromagnetic\nradiation<\/strong> between the infrared light and microwaves. These waves are\ncapable to penetrate and can yield an entirely different frequency for each\nchemical they encounter in their path. <strong>Terahertz\nfrequency<\/strong> can differentiate between ink and paper unlike the X \u2013rays. There\nare some tiny pockets of air present in between the pages of books. Scientists\nhave used these air pockets to emit the radiation via <strong>terahertz camera<\/strong>.<\/p>\n\n\n\n<p><strong>Terahertz\ncamera<\/strong> sensors\ncan detect the radiation and scientists use the total time of arrival back to\nthis sensor to gauge which reflects the distance of each page.&nbsp; This information for the page distance uses\nan algorithm to extract the information about the present chemical properties,\nwhich can be ink or paper or the reflecting surfaces to identify the letters on\nthe pages. <\/p>\n\n\n\n<p>This defines the correct page order and letter sequence to the researchers. To date, the researchers can read only nine pages at a time from the stacked papers or books. But they are confident about the <strong>terahertz imaging<\/strong> and they believe it is a kind of magic that is going to improve the accuracy of used detectors. With these <strong>detectors and power radiation<\/strong> sources, we will be able to read any books from beginning to end. <\/p>\n\n\n\n<p>Wait for this magic!!!<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Have you seen the \u201cHarry Potter\u201d?
