British physicist Brian Cox is challenged by the presenter of Radio 4's 'Life Scientific', Jim Al-Khalili, to explain the rules of quantum mechanics in just a minute. Brian succeeds; while conceding that the idea that everything is inherently probabilistic, is challenging. Even Einstein found it difficult.

Physics is an amazing science, that is incredibly tedious to learn and notoriously difficult.
Let's learn pretty much all of Physics in under 15 minutes.
Explaining all of physics would take more than 14 minutes.
Obviously I can't get ALL of physics in that small timeframe, but I tried my best to get all of the stuff worth knowing for most people, and explaining it as simply as possible, as fast as possible ;)

What’s better than slipping and sliding in your backyard on a hot summer day? It’s so much fun! But, how does this fun happen? It has a little something to do with friction!

When refraction is involved, your world can be reversed. Try this easy science experiment you can do at home with a glass of water, a piece of paper, and a permanent marker. 🧑‍🔬 How does it work? The bending of light waves as they pass through water causes refraction.

https://youtube.com/shorts/wDGq6lgpC2E

Refraction is the bending of light as it passes through a medium with a different refractive index. When light travels from air into water, for example, it bends towards the normal line (an imaginary line perpendicular to the surface of the water) due to the change in the refractive index of the two mediums. This experiment demonstrates the principle of refraction and how it affects the way we perceive the world around us.

Among the world's largest science centers, the Museum of Science engages millions of people each year to the wonders of science and technology through interactive exhibitions, digital programs, giant screen productions, and preK – 8 EiE® STEM curricula through the William and Charlotte Bloomberg Science Education Center. Established in 1830, the Museum is home to such iconic experiences as the Theater of Electricity, the Charles Hayden Planetarium, and the Mugar Omni Theater. Around the world, the Museum is known for digital experiences such as Mission: Mars launching in 2022 on Roblox, and traveling exhibitions such as the Science Behind Pixar.
