Life Beyond Earth: The Fermi Paradox -- Or Why We Are Still Waiting to Meet Aliens
暫譯: 地球之外的生命：費米悖論──為什麼我們仍在等待與外星人相遇

Luigi Vacca is a plasma physicist with a doctoral degree from MIT in plasma physics and minor in philosophy . Additionally, he earned a Laurea cum Laude from La Sapienza in Nuclear Engineering. As a graduate student at MIT, he researched the physics of tokamaks at the MIT Research Laboratory of Electronics, where he participated in several internal publications. After earning his doctorate, Luigi decided to work for financial institutions because they paid better than doing physics research. His deep understanding of probability and statistics allowed him to design mathematical models of derivative instruments for the financial industry. He has published mathematical finance articles in established magazines for finance professionals. After the financial industry collapse in 2008, he moved on to AI, learning the inner workings of neural networks while studying at MIT. Since 2008, he has been working on AI applications in many of his tasks as head of machine learning. He holds a patent on artificial intelligence applied to healthcare. Currently, Luigi is working for an AI startup based in Philadelphia, where he designs models for giving wellness advice to customers. He constantly stays up-to-date on the latest scientific and philosophical advances, his passion being to seek scientific and philosophical answers to the mysteries of our time.

盧伊吉·瓦卡（Luigi Vacca）是一位等離子體物理學家，擁有麻省理工學院（MIT）等離子體物理學博士學位及哲學副修學位。此外，他在羅馬大學（La Sapienza）獲得了核工程的優等學位（Laurea cum Laude）。作為麻省理工學院的研究生，他在麻省理工學院電子研究實驗室研究托卡馬克（tokamaks）的物理，並參與了幾篇內部出版物。在獲得博士學位後，盧伊吉決定為金融機構工作，因為這比從事物理研究的薪水更高。他對概率和統計的深刻理解使他能夠為金融行業設計衍生工具的數學模型。他在知名的金融專業雜誌上發表了數學金融文章。2008年金融業崩潰後，他轉向人工智慧（AI），在麻省理工學院學習神經網絡的內部運作。自2008年以來，他在擔任機器學習負責人的多項任務中致力於AI應用。他擁有一項應用於醫療保健的人工智慧專利。目前，盧伊吉在一家位於費城的AI初創公司工作，設計模型為客戶提供健康建議。他不斷跟進最新的科學和哲學進展，熱衷於尋求對我們時代之謎的科學和哲學答案。
