Scientists at the Massachusetts Institute of Technology（麻省理工學(xué)院）have turned spider webs into music - creating an strange soundtrack that could help them better understand how the spiders output their complex creations and even how they communicate.
   The MIT team worked with Berlin-based artist Tomas Saraceno to take 2 D（two-dimensional）laser（激光）scans of a spider web，which were linked together and made into a mathematical model that could recreate the web in 3 D in VR（virtual reality）.They also worked with MIT's music department to create the virtual instrument.
   "Even though the web looks really random（隨機(jī)），there actually are a lot of inside structures and you can visualize（可視化）them and you can look at them，but it's really hard to grasp for the human imagination or human brain to understand all these structural details，" said MIT engineering professor Markus Buehler，who presented the work on Monday at a virtual meeting of the American Chemical Society.
   Listening to the music while moving through the VR spider web lets you see and hear these structural changes and gives a better idea of how spiders see the world，he told CNN. "Spiders use vibrations（振動(dòng)）as a way to locate themselves，to communicate with other spiders and so the idea of thinking really like a spider would experience the world was something that was very important to us as spider material scientists，" Buehler said.
   Spiders are able to build their webs without shelves or supports，so having a better idea of how they work could lead to the development of advanced new 3 D printing techniques. "The reason why I did that is I wanted to be able to get information really from the spider world，which is very weird and mysterious，" Buehler explajye.aied.In addition to the scientific value，Buehler said the webs are musically interesting and that you can hear the sounds the spider creates during construction. "It's unusual and eerie and scary，but finally beautiful." he described.
