Here's why:
* Limited formal education: Nobel received a basic education in his youth, but his family's financial struggles meant he couldn't attend university.
* Practical experience: He learned most of his knowledge through practical work and his father's business.
* Extensive self-study: Nobel was an avid reader and a lifelong learner, constantly researching and experimenting.
While he didn't have a university degree, his intelligence, dedication, and self-driven learning allowed him to achieve great things, ultimately becoming a renowned chemist, engineer, and inventor.
