Applications: Of Modern Physics
"Positron Emission Tomography" is literally powered by antimatter . Doctors inject a radioactive tracer that releases positrons; when these meet electrons in your body, they annihilate and produce gamma rays that the scanner detects to find tumors.
Solar panels work via the photoelectric effect , the very discovery that earned Albert Einstein his Nobel Prize. It describes how light hitting a material can "knock" electrons loose, creating an electric current.
Every time you unlock your smartphone, you are using quantum mechanics. Applications Of Modern Physics
If engineers didn't program the satellites to compensate for this time difference, your GPS location would be off by several kilometers within a single day. 4. Sustainable Energy and Materials
GPS satellites orbit the Earth at high speeds and are further away from the Earth’s gravitational pull than we are. According to Special and General Relativity, time actually moves faster for the satellites than it does for us on the ground (by about 38 microseconds per day). It describes how light hitting a material can
If you’ve ever used Google Maps to find a coffee shop, you’ve used .
While currently in the experimental stage, fusion (the process that powers the sun) represents the "holy grail" of physics—providing near-limitless clean energy by fusing hydrogen isotopes together. 5. The Future: Quantum Computing and Beyond We are currently entering the era of "Quantum 2.0." 2. Healthcare and Medical Imaging
Modern medicine is perhaps the greatest beneficiary of particle physics.
The quest for clean energy is a journey into the heart of the atom.
The "Solid State Drives" (SSDs) in your laptop use a phenomenon called quantum tunneling , where electrons pass through a barrier that should be impassable according to classical physics. 2. Healthcare and Medical Imaging
