Einstein Proposes Mass-Energy Equivalence
In November 1905, Albert Einstein published a pivotal paper in the journal Annalen der Physik, introducing the concept of mass-energy equivalence encapsulated in the formula E = mc². This groundbreaking theory posited that mass could be converted into energy and vice versa, fundamentally altering the understanding of physics. Einstein's paper outlined the theoretical implications of this relationship, leading to profound consequences for both theoretical and applied physics. The publication was based on earlier works and theoretical insights that Einstein had developed during his time as a patent examiner in Bern, Switzerland.

Albert Einstein introduced the special theory of relativity through his paper published in the journal 'Annalen der Physik.' This groundbreaking theory fundamentally changed the understanding of space, time, and energy. A key aspect of the theory is the equation E=mc², which highlights the equivalence of mass and energy. This work laid the foundation for modern physics, influencing various fields such as cosmology and quantum mechanics.

Max Planck presented his groundbreaking work on black-body radiation, offering a new theoretical framework that would revolutionize physics. The formulation stemmed from attempts to explain the observed spectrum emitted by perfect black bodies, which traditional physics could not adequately describe. Planck's law, derived from his theoretical research, introduced the concept of quantized energy levels. This innovative idea was presented at a meeting of the German Physical Society in Berlin, marking a pivotal moment in the development of quantum theory.

J. J. Thomson presented groundbreaking findings at a lecture at the Royal Institution in London, revealing the existence of the electron, a subatomic particle far smaller than a proton. His experiments with cathode rays led him to conclude that these particles were fundamental constituents of atoms. This discovery challenged previous atomic models and opened new doors in the field of atomic physics, setting the stage for modern quantum mechanics.

Wilhelm Röntgen, a German physicist, published a groundbreaking paper in 1895 that described a new type of radiation resulting from the use of a cathode ray tube. This radiation, which he named 'X-rays,' had the unique ability to penetrate opaque substances, allowing for the imaging of bones and internal structures in living organisms. Röntgen's initial experiments produced striking images, famously demonstrating the skeletal structure of his wife's hand. This discovery opened new avenues in medical diagnostics.

Wilhelm Röntgen, while experimenting with cathode rays at the University of Würzburg, stumbled upon a new type of ray that could penetrate solid objects. During his experiments, he noticed that a nearby fluorescent screen was glowing even though it was not in the path of the cathode rays. After further investigation, Röntgen realized he had discovered a revolutionary form of radiation, which he called X-rays due to their unknown nature at the time. This remarkable finding would transform imaging and diagnostics in medicine.
