Recently, a middle school physics teacher in Ganzhou, Jiangxi Province released the "Paper Cup Gramophone" video that became popular on the Internet. The teacher said that the "paper cup phonograph" was designed by a friend, not a new invention. It just used the working principle of the previous phonograph and made it for teaching. Through experiments, students and the public should be aware of the need for innovation and invention.

After eating the chicken, can the bones be assembled into a complete skeleton? Netizen: I thought it was a joke, but it turned out to be true!

z40The immortal teacher who is both eating and attending class is called Lu Jing. He is an associate researcher at the Institute of Vertebrate Paleontology and Paleoanthropology of the Chinese Academy of Sciences. His research field is Paleoichthyology. After
feasted, deboned, washed, dried, and spliced the food debris until the scattered bones became a complete skeleton teaching aid.
someone ridiculed and said: "When I meet Mr. Lu, restaurants are afraid to cut corners." Before
, she tried to spread her professional knowledge in various ways: publishing popular science articles, giving lectures in museums... "If you want to say me The biggest science popularization I have ever done is to work with the teacher to compile the chapter of palaeoichthyology in the sixth edition of "One Hundred Thousand Whys"." Lu Jing said, these are more traditional methods.
Until May of this year, Lu Jing participated in the review of a popular science video. As a distinguished expert of the China Science and Technology Press, this was originally only part of her daily work, but it gave her the idea of using short videos to popularize paleontology.
"If you directly talk about the structure of these bones, a lot of background knowledge will be daunting. We think of cutting in from a familiar angle." She said, "The most common opportunity for everyone to come into contact with bones is at the dinner table. By assembling the bones of common foods, it aroused everyone's interest. "
So, she released the first video on "Ms. Lu Playing with Bones": Turning the fat head fish skull in the fish head bubble cake into a bone specimen.
Lu Jing said: “It’s funny when I think about it now, because we chose a super difficult beginning for ourselves. The bones of fish are the most common among common animals, and the most complicated, and the fish bones that have just been eaten are a bit oilier. It’s not easy to fit and sticky. The first video took seven or eight hours.”
