While not explicitly shown, it's heavily implied Bulma displayed exceptional scientific aptitude from a young age, given her later accomplishments. This period likely involved advanced learning and experimentation far beyond typical childhood levels.

At just 16, Bulma invents the Dragon Radar, a revolutionary device capable of detecting the energy signatures of the Dragon Balls. This invention is the catalyst for the entire Dragon Ball saga, enabling her quest and indirectly shaping the fate of the universe.

During her journey with Goku, Bulma continues to refine and utilize Capsule Corp's capsule technology, essential for housing various vehicles and equipment. She likely gains more practical experience in its application and improvement.

Driven by Future Trunks' desperate plea, Bulma dedicates herself to building a Time Machine, a feat considered impossible by most. This project demands an unparalleled level of scientific understanding and engineering skill, pushing her abilities to their absolute limit. The time machine uses a dangerous fuel source and required years of reverse engineering of unknown technology from Trunks.

After the Cell Games, Bulma continues to improve upon her inventions. She researches and implements methods to train in extreme gravity like Saiyans, creating training chambers. The focus is on supporting the Z Fighters and advancing Earth's technology.

In Dragon Ball Super, Bulma creates a device to detect God Ki, enabling the Z Fighters to locate powerful beings like Beerus and Whis, showcasing her ability to adapt to the ever-escalating power levels of the universe. This is non-canon, as it occurs solely in the anime.

Bulma remains a vital scientific resource, offering technological assistance and insights to the Z Fighters in their ongoing battles against various threats. Her contributions are crucial in maintaining Earth's defense and understanding new phenomena.
