What was alberts first creation?

Answer 1

Albert Einstein's first significant scientific contribution was the paper he published in 1905 on the photoelectric effect, which proposed that light can be thought of as discrete packets of energy called photons. This work was pivotal in establishing the foundation of quantum theory and earned him the Nobel Prize in Physics in 1921. Additionally, 1905 is often referred to as Einstein's "annus mirabilis" or "miracle year," during which he published four groundbreaking papers, including his theories of special relativity and mass-energy equivalence (E=mc²).
