The biggest mystery of my Spotify wrapped this year is 大风吹, the song featured in many of 王七叶’s videos. I played it maybe three or four times, but it made it to spot #8 on my top songs (just ahead of VENOM by BVNDIT, which I literally learned the dance to this year. I listened to VENOM dozens, if not over a hundred, of times to dance to it).
Why is it here? How did I play it so much without noticing? Did someone hack my account just to play Windy a hundred times? Did I accidentally fall asleep to Windy one night??? How??
Another face study! I had to break out the eyedropper towards the end to try and troubleshoot some areas, this one's entire everything was weirdly difficult.
Why do people keep calling wang qiye the johnny bravo lady when her name is already right there… even if you can’t read the characters (i can’t) it’s a quick check of the notes to see where people have mentioned her name

Aerogel Can Become the Key to Future Terahertz Technologies - Technology Org
High-frequency terahertz waves have great potential for a number of applications including next-generation medical imaging and communication. Aerogels could be a nice addition to this.
Researchers at Linköping University, Sweden, have shown, in a study published in the journal Advanced Science, that the transmission of terahertz light through an aerogel made of cellulose and a conducting polymer can be tuned. This is an important step to unlock more applications for terahertz waves

The terahertz range covers wavelengths that lie between microwaves and infrared light on the electromagnetic spectrum. It has a very high frequency.
Thanks to this, many researchers believe that the terahertz range has great potential for use in space exploration, security technology and communication systems, among other things. In medical imaging, it can also be an interesting substitute for X-ray examinations as the waves can pass through most non-conductive materials without damaging any tissue.
However, there are several technological barriers to overcome before terahertz signals can be widely used. For example, it is difficult to create terahertz radiation in an efficient way and materials that can receive and adjust the transmission of terahertz waves are needed.
Adjustable filter
Researchers at Linköping University have now developed a material whose absorption of terahertz signals can be turned on and off through a redox reaction. The material is an aerogel, which is one of the world’s lightest solid materials.
“It’s like an adjustable filter for terahertz light. In one state, the electromagnetic signal will not be absorbed and in the other state it can. That property can be useful for long-range signals from space or radar signals,” says Shangzhi Chen, postdoc at the Laboratory of Organic Electronics, LOE, at Linköping University.
The Linköping researchers used a conducting polymer, PEDOT:PSS, and cellulose to create their aerogel. They also designed the aerogel with outdoor applications in mind. It is both water-repellent (hydrophobic) and can be naturally defrosted via heating by sunlight.
Large modulation range
Conducting polymers have many advantages over other materials used to create tunable materials. Among other things, they are biocompatible, durable, and have a great ability to be tuned. The tunability comes from the ability to change the charge density in the material. The great advantages of cellulose are the relatively low production cost compared to other similar materials and that it is a renewable material which is key for sustainable applications.
“The transmission of terahertz waves in a broad frequency range could be regulated between around 13 % and 91 %, which is a very large modulation range,” says Chaoyang Kuang, postdoc at LOE.
The study was funded by, among others, the Swedish Research Council, the Foundation for Strategic Research, the Foundation for Internationalization of Higher Education and Research, the Knut and Alice Wallenberg Foundation, the Wallenberg Wood Science Centre, and through the Swedish government’s strategic initiative in new functional materials, AFM, at Linköping University.

Facts: The terahertz range covers the wavelengths that lie between microwaves and infrared light on the electromagnetic spectrum. The waves have a width of between 0.1 and 1 millimetre and the frequency is at least 0.3 terahertz and at most 30 terahertz. 1 terahertz means that 1000 billion waves are sent or received in one second.

thought i liked di wang gong lue a normal amount but then the "Is there a person you'd never ever use? [...] What about Duan Baiyue?" - "Not in the future, but in the past... his every injury and illness, were all because of me" conversation excavated my insides with a spoon
man i wish the chinese johnny bravo joke would die
I assume most people on here have not actually seen Johnny Bravo in at least 10 years and don't remember anything about the character but it is rather unfortunate that the Wang Qiye character has been reduced to "female Johnny Bravo" in some people's minds, not least of which is because it's a weak comparison if you watch more than like 1 video.
Now that I type this, I'm guessing the Johnny Bravo comparisons come from 1) cartoonish walking; 2) hitting on strangers; 3) egotistical; and 4) in the original video that blew up on here, Wang Qiye corners the guy up against the wall, which is probably reminiscent of Johnny Bravo getting up in peoples' spaces in the old cartoons.
However Wang Qiye's humor comes more from a style of humor being slightly unhinged and perverse (变态). I would say the character is more supposed to be more predatory/a menace rather than the Johnny Bravo brand of goofy muscle-head. She's clever and money-hungry yet often broke, though she doesn't let anything affect her because as far as she's concerned it's her world and everyone else is just living in it. The fact that handsome men run away from her is part of the appeal for the character because she likes pulling power moves.
So the Johnny Bravo joke is annoying but ultimately harmless I think. If you watch a Wang Qiye video where she's playing word games with Chinese idioms and think "man this is just like female Asian Johnny Bravo" then that's sort of your loss, isn't it?
But also yes. "Omg female Asian version of this unrelated white man!" ==> 🤡
