Explanation:
1 – Antibiotics
Antibiotics revolutionised medicine in the twentieth century, and together with vaccinations, have almost completely eradicated many once-common diseases such as tuberculosis. While the use of mould to treat infections was first noted by ancient civilisations such as the Egyptians and the Greeks, it was Sir Alexander Fleming who discovered the first antibiotic substance, Penicillin G. For the millions of lives that antibiotics have, and continue to, save worldwide, antibiotics have to be in my scientific top five.
2 – DNA
Over the last 60 years, our rapidly evolving understanding of DNA has catapulted medical knowledge and treatments and even transformed the way we solve crimes. Since James Watson and Francis Crick’s discovery of the double helix structure of DNA in 1953, the scientific community has split in many different directions to investigate the building blocks of life to understand what makes us who we are. Without the discovery of DNA, we wouldn’t have all the ground-breaking studies going on right now in genome mapping and sequencing, so for that reason, DNA has to be my number one scientific discovery of all time.
3-The idea of an atom-
The idea of atoms stretches back to ancient Greece when the philosopher Democritus declared that all matter is made of tiny particles. The philosopher Plato even decided-- wrongly-- that different substances had different shaped atoms, like pyramids or cubes. The first modern evidence for atoms appears in the early 1800s when British chemist John Dalton discovered that chemicals always contain whole number ratios of atoms.
4 – Medical imaging
Medical imaging is an essential tool for clinical analysis, allowing doctors to see beyond what is hidden by skin and bone to accurately diagnose and treat diseases. From X-rays and radiography to MRI scans and ultrasound technology, these scientific innovations have all helped to ensure modern medicine is the least invasive it can be while ensuring the best outcomes for patients. Medical imaging really showcases how science and technology are complementary disciplines, as one advances the other. Marie Curie played a vital role in discovering radioactive elements to do radioactive scans
