Interstellar
Interstellar is a 2014 science fiction film directed by Christopher Nolan. Starring Matthew McConaughey, Anne Hathaway, Jessica Chastain, Mackenzie Foy and Michael Caine, the film features a team of astronauts who travel through a wormhole in search of a new habitable planet. Brothers Christopher and Jonathan Nolan wrote the film, merging a script Jonathan developed in 2007 with Christopher's ideas. Christopher Nolan produced the film with his wife, Emma Thomas, and Lynda Obst. Theoretical physicist Kip Thorne, whose work inspired the film, acted as scientific consultant and executive producer.In the future, crop blight has caused civilization to regress into a failing agrarian society. Former NASA pilot Cooper (Matthew McConaughey) runs a farm with his father-in-law, his teenage son, and his 10-year-old daughter Murphy (Mackenzie Foy). Murphy believes her room is haunted by a ghost trying to communicate with her. She and Cooper discover the "ghost" is an unknown intelligence sending coded messages using gravitational waves, leaving binary coordinates in the dust that direct them to a secret NASA installation led by Professor Brand (Michael Caine). Brand reveals that a wormhole, apparently created by an alien intelligence, offers a chance for humanity's survival on a new planet. Using it, NASA's "Lazarus missions" have identified three potentially habitable planets orbiting the black hole Gargantua: Miller, Edmunds, and Mann, named after the astronauts who surveyed them. Brand recruits Cooper to pilot thespacecraft Endurance to recover the astronauts' data; if one of the planets is habitable, humanity will follow on space stations whose technology he promises will be ready for their return. Cooper's decision to leave devastates Murphy, and they part on bad terms.On Endurance, Cooper joins Brand's daughter, biologist Amelia (Anne Hathaway); physicist Romilly (David Gyasi); geographer Doyle (Wes Bentley); and robots TARS (voiced by Bill Irwin) and CASE (voiced by Josh Stewart). They enter the wormhole and head to Miller, but discover the planet is so close to Gargantua that it experiences severe gravitational time dilation: each hour on the surface is seven years on Earth. They descend to the planet, which proves inhospitable as it is covered by a shallow ocean roiled by enormous tidal waves. As Amelia attempts to recover Miller's data, a wave hits, killing Doyle and delaying the shuttle's departure. When Cooper and Amelia returnto Endurance, 23 years have passed.On Earth, the adult Murphy (Jessica Chastain) is now a NASA scientist assisting Brand with the equation that will enable NASA to launch its massive space stations via gravity. On his deathbed, Brand admits he already solved the problem and determined the project is impossible; he covered up his conclusion and put his faith in a "Plan B": using fertilized embryos to start humanity anew. However, Murphy demonstrates that Brand's equation could work with additional data from a black hole's singularity.Low on fuel, Endurance can only visit one more planet before returning to Earth. Amelia believes Edmunds' planet has the more promising data, but Cooper and Romilly favor Mann's planet, as Mann (Matt Damon) is still transmitting. Cooper accuses Amelia of letting her emotional attachment to Edmunds cloud her judgment, while Amelia argues they could explore both planets if Cooper would give up on returning to Earth. The teamvotes for Mann's planet, but they find it to be icy and inhospitable. Mann reveals that he knew Plan B was the mission's goal all along, and faked data about his planet's viability so Endurance would rescue him. Mann breaks Cooper's spacesuit visor and leaves him to die; Romilly dies when he triggers a bomb Mann set to protect his secret. Mann fleesto Endurance on a shuttle, intending to proceed with Plan B on Edmunds' world. Amelia rescues Cooper on the other shuttle and they arrive at Endurance in time to witness Mann docking improperly. The airlock depressurizes, killing Mann and causing serious damage, but Cooper uses the shuttle to get Endurance under control.Nearly out of fuel, Cooper and Amelia plan to slingshot Endurance around Gargantua on a course toward Edmunds. TARS and Cooper detach into the black hole, hoping to collect data on the singularity and propel Amelia by dropping mass from the ship. They emerge in an extra-dimensional "tesseract" where time appears as a spatial dimension and portals lead to Murphy's childhood bedroom at various times. Cooper surmises that the theextra-dimensional beings are future humans who have created this space so he can communicate with Murphy as the "ghost" and save humanity. Using gravitational waves, he transmits TARS's data on the singularity to the adult Murphy through Morse code, allowing her to solve Brand's equation and evacuate Earth. Cooper later awakes aboard a NASA space station and reunites with the now elderly Murphy. She convinces Cooper to search for Amelia, who has reached Edmunds' planet.。

(注：本文希望更多地介绍以西方的研究成果和资料为基础的观点和见解，所以中国的研究成果和材料只被有限地运用。
)Allott在20年前曾说：“法律常常是无效的，几乎从它一出现就注定是一种愚弄，是立法者过度的雄心的结果，它也常常达不到有效法律的必备条件，例如充分的初步调查机制、交流机制、接受机制和实施机制。
”[1](P287)法律失败(Legal Failure)在于它的无效或过度有效，正像Teubner所言：可能“导致不确定、混乱、不信任或者仇视，而不是适当的管理。
”[2]就法律失败而言，国家法并不能实现有关正义、确定性、统一性、社会团结和社会控制的存在固有矛盾的允诺。
那些曾预测法律失败的人(注：参见Savigny，F.K.von.Of the Vocation of Our Age for Legislation and Jurisprudence(Translated by A Hayward).Arno Press，1831(ed.1975)；Sumner，W.G.Folkways.New American Library，1906(ed.1960).)和那些意识到法律失败的人(注：参见Pound，R.The Limits of Effective Legal Action.International Journal of Ethics 27(1917)；Ehrlich，E.Fundamental Principles of the Sociology ofLaw( Transl by W.L.Moll).Arno Press，1936(ed.1975)；Allott，A.N.The Limits of Law .Butterworths，1980；De Soto，Hernando.The Mystery of Capital，Why Capitalism Triumphs in the West and Fails Everywhere Else.Black Swan，2000； Otto，J.M.The Mystery of Legal Failure and the Mastery of Legal Education.I.

多天线接收原理
多天线接收原理The principle of multiple antenna reception is a key concept in wireless communication systems.多天线接收的原理是无线通信系统中的一个关键概念。
By using multiple antennas, a system can achieve diversity reception, which helps improve signal reliability in the presence of fading and interference.通过使用多个天线，系统可以实现多样性接收，有助于提高在衰落和干扰存在的情况下的信号可靠性。
In addition to diversity reception, multiple antennas can also be used for spatial multiplexing, which enables higher data rates by utilizing the spatial dimension of the communication channel.除了多样性接收外，多个天线还可以用于空间复用，通过利用通信信道的空间维度实现更高的数据速率。
Another benefit of multiple antenna reception is the ability to exploit spatial diversity, where the spatial separation between antennas can be utilized to mitigate the effects of multipath fading.多天线接收的另一个好处是利用空间多样性，可以利用天线之间的空间分离来减轻多径衰落的影响。
Antenna diversity is an effective technique to combat fading and improve the reliability of a wireless communication link.天线多样性是解决衰落问题并提高无线通信链路可靠性的有效技术。
从拉康哲学的视角看元宇宙
从拉康哲学的视角看元宇宙作者：曾文勇来源：《西部学刊》2024年第13期摘要：从法国哲学家雅克·拉康的理论视角，结合其“实在界、象征界、想象界”的“三界”理论和拓扑学的观点，分析了元宇宙的超越性问题、结构问题、主体性问题，认为元宇宙是人类在自己生存环境中嵌入的一个独特的空间维度。
元宇宙中的主体不再纯粹依赖现实世界，伴随着大他者的退隐，主体获得了一种不被大他者所掌控的“自由感”。
然而数字大他者在元宇宙中的返场，预示着主体实现真正的回归终究只是一种幻想。
通过探讨主体在元宇宙的存在状况，为在哲学层面上思考分析元宇宙提出了思想进路。

The subject in the Metaverse is no longer purely dependent on the real world， and with the retreat of the Big Other， the subject gains a sense of freedom that is not controlled by the Other. However， the return of the Big Digital Other in the metaverse indicates that the true return of the subject is ultimately just a fantasy. By exploring the condition of the subject’s existence in the Metaverse， it suggests a way forward for thinking about and analyzing the Metaverse on a philosophical level.Keywords：Jacques Lacan; Metaverse; “three orders”; subject關于元宇宙（Metaverse）的概念，比较一致的观点认为是出自美国科幻作家尼尔·斯蒂芬森（Neal Stephenson）1992年出版的科幻小说《雪崩》（Snow Crash）。
