Einstein's attitude towards learning facts can be summarized as the belief that learning facts alone does not constitute true education. This aligns with option B, which states that he believed learning facts was not education. Let's delve into the details to understand why this is the correct answer.

Einstein's Approach to Learning:
- Albert Einstein was a renowned physicist and a strong advocate for deep understanding and critical thinking. He believed in the importance of developing a conceptual understanding of the world rather than merely memorizing facts.
- Einstein emphasized the value of curiosity and questioning, stating that "the important thing is not to stop questioning." He believed that true education involved actively engaging with knowledge and constantly seeking to uncover the underlying principles and connections.

Einstein's Critique of Rote Memorization:
- Einstein criticized the prevalent education system of his time, which focused on rote memorization of facts without fostering true understanding. He believed that this approach hindered students' ability to think critically and develop creative problem-solving skills.
- According to Einstein, simply memorizing facts without comprehending their meaning and context was futile. He stated, "Education is not the learning of facts, but the training of the mind to think."

Importance of Conceptual Understanding:
- Einstein emphasized the significance of grasping fundamental concepts rather than simply accumulating a vast array of isolated facts. He believed that a solid conceptual foundation allowed individuals to apply their knowledge in various contexts and make meaningful contributions to society.
- By focusing on understanding the principles and theories behind the facts, Einstein believed it was possible to develop a deeper comprehension of the subject matter and encourage critical thinking.

Conclusion:
In conclusion, Einstein's attitude towards learning facts was that it alone does not constitute true education. He believed in the importance of conceptual understanding, critical thinking, and questioning. Einstein's views highlight the need to move beyond rote memorization and instead focus on actively engaging with knowledge to develop a deeper understanding of the world. Therefore, option B, which states that Einstein believed learning facts was not education, accurately encapsulates his perspective.
