1 . A BioBlitz is an event that focuses on finding and identifying as many species(物种) as possible in a given area over a short period of time. A BioBlitz is also known as a biological inventory(清单). The main goal of a BioBlitz is to get an overall(全面的) list of the plants, animals, and other species that live in a place.
A BioBlitz has its own features different from a scientific inventory. Scientific inventories are usually limited to biologists, geographers, and other scientists. A BioBlitz brings together volunteer scientists, as well as families, students, teachers, and other members of the community. While a scientific survey often focuses on faraway or isolated areas, BioBlitzes involves places that are connected to a living or industrial areas. Finally, scientific surveys may take a long period of time to conduct. A BioBlitz lasts a short period of time, traditionally 24 hours.
These differences make a BioBlitz a unique biological survey that encourages a relationship between the nature and human communities of a certain area. Citizens work together with scientists to learn about the biological diversity of local natural spaces. In the process, they gain skills and knowledge and develop a stronger connection to their home environment. A BioBlitz makes citizens better understand and protect local natural spaces.
Hundreds of BioBlitzes have been conducted all over the world, mainly in the United States. Canada, Australia, and Europe. The first BioBlitz was sponsored by the National Park Service and the National Biological Service in Washington D.C.’s Kenilworth Park and Aquatic Gardens in 1996. Surrounded by heavy living and industrial development, Kenilworth Park was thought to have very little biological diversity. Scientists, however, recorded more than 900 species that first year and added even more species to their list at continuous Kenilworth BioBlitzes.

2 . Quantum mechanics (量子力学) is a branch of science that studies the smallest particles (粒子) in the universe, like atoms (原子) and even smaller things. It might sound super complex, but let’s break it down in simple language.
Imagine you have a small particle, like an atom. In the world of quantum mechanics, these particles don’t behave like the things we see in our everyday lives, like balls or cars. Instead, they act kind of like waves and particles at the same time, which is really strange!
One of the most famous ideas in quantum mechanics is the “Uncertainty Principle”, raised by physicist Werner Heisenberg. This principle says that we can’t precisely know both the position and the speed of a particle at the same time. It’s not because our measuring tools are bad; it’s because the particles themselves are naturally uncertain.
Another weird thing about quantum mechanics is something called “Entanglement.” Imagine you have two particles that are connected in a special way. If you change one of them, the other instantly changes, no matter how far apart they are. It’s like they’re talking to each other faster than the speed of light, which goes against what we know from everyday experiences.
Quantum mechanics also deals with probabilities. Instead of saying, “This particle will be here at this exact time,” scientists say, “There’s a certain chance it’ll be here, and a certain chance it won’t.” It’s like predicting the weather, but on a super small scale.
In a nutshell, quantum mechanics is a strange and fascinating world where particles act both like waves and particles, where you can’t know everything about a particle at once, and where particles can be mysteriously connected no matter how far apart they are. It’s a mind-boggling field that challenges our understanding of how the universe works, and even though it’s tough to grasp, it’s an essential part of modern physics.
