Scientists finally succeeded in exiting an atomic resonance with a laser in the near ultraviolet. It's a remarkable feat that they've been working on since the 1970s. It could usher in the era of nuclear precision. Let’s have a look.

Just for some scalar fun - if you were to convert the scale of an Attosecond (10^-18s) to a Second, our seconds would appear to be ~32 billion years long, or over twice the age of our universe. But if that scale seems bizarre, consider that if we were to scale a Planck Second (10^-44s) up to the scale of seconds, a single Attosecond would now take over 3 quintillion years to pass, and a full second would be over 100 tredecillion years long (I had to look that word up...;P) In other words, the very smallest slices of time that we can currently measure are still nearly endless eternities compared to the smallest units of time that our theories can describe. (10^-44s)

@ralftest4373 25 дней назад

It is clear that this format of scientific information cannot meet the standards of a respectable scientist. The humor or irony with which Sabine masks this can also be seen as her method of conveying information in a RU-vid-appropriate manner. I am a math and physics teacher and I sell my content so far reduced didactically that structure often gets lost or becomes indiscernible. However, I see this as a benefit for my students, as this information would otherwise not reach them, or they would hardly retain it. I would now like to sincerely thank Sabine for providing this didactic reduction for me as the recipient of the information. It's enjoyable to watch Sabine! I hope the scientific community sees it that way too, at least in the field of science journalism. So, thanks again to Sabine!
