# Hidden Dimensions: Exploring Hyperspace

TLDRIn this intriguing program, Brian Greene introduces the groundbreaking discovery made by German mathematician Theodor Kaluza in 1919. While working in his study with his young son, Kaluza experienced an epiphany that led him to consider the possibility of our universe having more than the three spatial dimensions we are accustomed to. The program delves into the implications of this idea, exploring its impact on physics over the past eighty years and discussing the current state of thought on the existence of additional dimensions beyond our perception.

###### Q & A

### Who was Brian Greene referring to when he mentioned a 34-year-old German Mathematician?

-Brian Greene was referring to Theodor Kaluza, a German mathematician who was 34 years old in 1919.

### What significant discovery did Theodor Kaluza make in 1919?

-Theodor Kaluza discovered the possibility that our universe might have more than the three dimensions of everyday space.

### What was the setting described in the script when Theodor Kaluza made his discovery?

-The setting was Kaluza's study, where he was sitting at his desk with his 9-year-old son on the couch, often being present while his father worked.

### What was Theodor Kaluza's reaction upon making his discovery?

-Upon making his discovery, Kaluza opened his eyes wide, slammed the desk with his hands, stood up, and began to sing an Aria from Figaro.

### What is the significance of the Aria from Figaro in the script?

-The Aria from Figaro symbolizes Kaluza's excitement and joy upon making his groundbreaking discovery about the nature of our universe.

### What theme will the program explore based on the script?

-The program will explore the theme of the possibility of our universe having more dimensions than the three we are familiar with.

### What variations on the theme of extra dimensions have rippled through physics over the last eight decades?

-The script does not provide specific details, but it suggests that there have been significant developments and discussions in the field of physics related to the concept of extra dimensions since Kaluza's time.

###### Outlines

##### 🎶 The Eureka Moment of Theodor Kaluza

In April 1919, Theodor Kaluza, a 34-year-old German mathematician, experienced a significant breakthrough while working in his study. During this moment, his 9-year-old son was present, often accompanying him. Kaluza, deeply immersed in his calculations, suddenly reacted with great excitement. He abruptly stood up, slammed his desk, and began singing an aria from Figaro. This pivotal moment marked Kaluza's realization of a groundbreaking idea: the possibility that our universe might have more than the familiar three dimensions of everyday space. The evening's program delves into this revolutionary concept, tracing its evolution over the past eight decades and exploring current theories on the existence of additional dimensions, with references to the work of Calabi-Yau.
