Physics In Your Life: Nuclear Matters
Things I learned:

• Water made with Oxygen-16 and water made with Oxygen-18 evaporate at different rates because their mass is different.
• Process of Fission – Uranium-235 hit by neutron, U-235 becomes U-236, U-236 vibrates, structure becomes elongated, eventually splits, sends neutrons everywhere, neutrons collide with more U-235, creates a chain reaction.
• Only U-235 readily fissions.
• U-235 only makes up about 0.7% of all natural Uranium.
• A half life is the time until half the nuclei decay.

Physics In Your Life: Physics in your body
Things I learned:

• CAT = Computerized Axial Tomography.
• MRI= Magnetic Resonance Imaging.
• PET = Positron Emission Tomography.
• Laser eye surgery basically weld retina back onto the back of the eye.
• Laser surgery causes less bleeding versus a regular scalpel because the protein in the tissue instantly coagulates.
• Steady electric current and ultrasound can help heal broken bones.
