1. 나비에-스토크 방정식의 의미와 로켓 기술의 역사에 대한 강의를 듣고 있는데, 폰 칼만이 바람의 영향으로 발생한 타코마 브릿지의 무너짐 원인을 설명하고, 고다드의 액체 추진 로켓에 대한 이론을 다룹니다.

A lecture on the significance of the Navier-Stokes equation and the history of rocket technology. The speaker, Von Kármán, explains the cause of the collapse of the Tacoma Bridge due to the influence of wind and discusses the theory of Goddard's liquid propulsion rocket.

 


2. 칼만의 제자인 최 세이가 중국에서 로켓 기술을 공부하기 위해 노력하며, 수어사이드 스쿼드라는 동아리를 통해 연구소로 발전하는 과정과 고체 연료로 인한 화약 문제를 다룹니다.

Karlman's disciple, Choe Sei, strives to study rocket technology in China and establishes a club called Suicide Squad, which later evolves into a research institute. The lecture covers the challenges related to solid fuel and explosive issues.

 


3. 치올콥스키 로켓 방정식을 통해 로켓 속도 증가와 가속도 관련 이론을 설명하며, 고다드의 액체 추진 로켓의 중요성과 고체 로켓의 한계를 다룹니다.

Explaining the Chiołkowski rocket equation, the lecture delves into theories of rocket speed increase and acceleration. It emphasizes the significance of Goddard's liquid propulsion rocket and discusses the limitations of solid rocket technology.

 


4. 헤디 라마르는 무선 통신과 암호화에 관한 연구를 통해 무선 통신의 원천과 특허에 대한 이야기를 하며, 오스트리아 출신인 라마르가 미국으로 망명하고 헐리웃에서 과학자 과외를 받는 경험을 다룹니다.

Hedy Lamarr discusses her research on wireless communication and encryption, highlighting the origin and patents of wireless communication. The lecture also covers Lamarr's experience as an Austrian seeking refuge in the United States and receiving scientific tutoring in Hollywood.

 


5. 오스트리아 국가가 왜곡되어 불쾌한 마음을 가지고 있던 헤디 라마르가 원하는 알람 소리를 특허로 내고, 이에 따른 부정적인 반응과 90년대 이후 무선통신과 휴대전화의 발전에 대한 이야기를 다룹니다.

Hedy Lamarr, who disliked the distortion of the Austrian national anthem, patents her desired alarm sound, leading to negative reactions. The lecture then discusses the development of wireless communication and mobile phones since the 1990s.
