Quantum Mechanics it’s not just a theory for small things

Quantum Mechanics it’s not just a theory for small things

In this video I explain that quantum mechanics is not merely a theory for short distances, as it is often portrayed. Quantum mechanics applies to all objects, regardless of size. Indeed, quantum effects are necessary to explain many rather mundane observations: the sun shines, atoms are stable, laser light is strongly focused and coherent.

Correction: The map at 5 mins 13 secs does not show the islands of Tenerife and La Palma but, mistakenly, the islands of Tenerife and Gran Canaria (the captial of which is Las Palmas). Lots of palms there, I figure. ht Jose de la Puente for pointing out.

Note: The animation at 1 mins 31 secs does not show what really happens if an electron hits an atomic nucleus. It merely illustrates « this is not how atoms work ». If an electron hits an atomic nucleus, there constituents of the nucleus most definitely do not fly off in all directions!
