Tiny Science, Big Impact: How Quantum Physics Helps Us
Every Day by Cory

Quantum physics is the science of the very small. It studies how tiny particles like atoms and electrons move and behave. These particles don’t always follow the usual rules of physics, which makes quantum physics seem strange However, even though it’s challenging to comprehend, this science underlies many of the tools and technologies we use on a daily basis.
As explained by Cory Carnley, one of the most significant applications of quantum physics is in the field of electronics. Every smartphone, laptop, and TV works because of tiny parts called transistors These transistors are built using ideas from quantum mechanics Without them, we wouldn’t have the fast, powerful devices we rely on today
Quantum physics is also used in healthcare MRI machines, which doctors use to visualize the inside of the body, operate based on quantum principles. These machines utilize magnets and radio waves to study atoms within the body and produce clear images Thanks to this, doctors can detect injuries and diseases early and treat them better
Lasers are another invention made possible by quantum physics They are used in many areas from cutting metal in factories to correcting vision in eye surgery Supermarket scanners, DVD players, and even some beauty treatments also use lasers. All of this depends on how particles of light, known as photons, behave at the quantum level
You might be surprised to learn that quantum physics also helps you find your way. GPS systems use satellites that rely on very accurate atomic clocks These clocks measure time based on how atoms vibrate, and their accuracy is thanks to quantum science. Because of them, your phone can tell you exactly where you are on a map.
In the future, quantum physics could lead to even more amazing technology. Scientists are working on quantum computers, which could solve complex problems much faster than today’s computers There is also research into quantum communication, which could make internet messages completely secure and impossible to hack.
Even though we can’t see atoms or particles with our eyes, quantum physics affects our world in many ways. It helps us stay connected, stay healthy, and explore new frontiers in science. What seems like a mysterious part of science is working behind the scenes in our daily lives quietly making things better, faster, and smarter.
