Having been born in 1879 in a place called “Ulm” in Germany, Einstein was an “average” student in his class but showed some keen interest in science and mathematics. Little did anybody know at that time that he, as the firstborn of a Jewish couple called Hemann and Pauline Einstein, would one day change the course of history in science and physics. 

Einstein worked on many things like Brownian movement theory or the zigzag motion of microscopic particles in suspension, the quantum theory of light” and the “theory of relativity” in which Einstein explained that time and motion are relative to their observers as long as the speed of light remains constant. However, his most famous work, in my opinion, was the invention of the formula E = mc2, relating mass and energy, which later on formed much of the basis for nuclear energy.

Of course, we all already know about these inventions, but what many of us perhaps didn’t know that Einstein renounced his German citizenship when he was just 16. We also perhaps didn’t know that he married a female student in his physics class at Zürich Polytechnic in Switzerland. By the way, Einstein also spent all his prize money to pay for the divorce of his first wife. The fact that surprises me the most about him is that Einstein was asked to be Israel's second president, but he refused, stating that he had "neither the natural ability nor the experience to deal with human beings". But then I wonder this is exactly what one of the most prolific scientists of all time would and should do!

His inventions are still important and will remain so for a long, long time as they pretty much changed the idea of energy, motion and light, and how we use them to our advantage. In fact, the global positioning system, which we use today in our mobile applications, wouldn’t function without special and general relativity. Besides, Solar panels (photovoltaic panels) which convert the sun’s energy into electricity, and the photocell eyes, which are installed on the sides of the automatic doors, rely on the photoelectric effect, explained by Einstein. Finally, the electricity, that we use, is the result of nuclear energy, derived from his famous formula E = mc2.

Model Answer 3:

In my opinion, Marie Curie is a remarkable female scientist and inventor who has left an indelible mark on history. I am happy to have been given the chance to talk about this scientist, and thank you for that.

Marie Curie was a Polish-born physicist and chemist who became famous for her pioneering research on radioactivity. Her most significant contribution to science was her discovery of the elements polonium and radium. Together with her husband, Pierre Curie, and Henri Becquerel, Marie conducted groundbreaking experiments that led to the discovery of radioactivity, a term she coined herself.

One of the most interesting facts about Marie Curie is that she was the first woman to win a Nobel Prize and remains the only person to have received Nobel Prizes in two different scientific fields—Physics and Chemistry. In 1903, she was awarded the Nobel Prize in Physics alongside Pierre Curie and Henri Becquerel for their research on radioactivity. Later, in 1911, she received the Nobel Prize in Chemistry for her discovery of radium and polonium.

Despite facing significant challenges as a woman in the male-dominated scientific community of her time, Marie Curie's work laid the foundation for modern atomic physics and revolutionized the field of medical science. Her research on radioactivity paved the way for important applications in medicine, including the development of radiation therapy for cancer treatment.

In my opinion, Marie Curie's contributions to science remain highly relevant and important today. Her discoveries continue to influence various scientific disciplines, from physics and chemistry to medicine and technology. Moreover, her groundbreaking achievements have inspired generations of scientists, especially women, to pursue careers in STEM fields and strive for excellence in scientific research.
