What is Physical Information?

A lot of physicists talk about "information" and just assume you'll figure out what it means by context... probably because they don't actually understand it. Hopefully, this video will fix all that! We'll talk about how physical information fixes a few relativity problems as well as how it relates to entropy and digital information. ________________________________ VIDEO ANNOTATIONS Why is Light the Fastest Thing? http://youtu.be/Vmi_h5A8B2k Why Does Entropy Even Matter? http://youtu.be/qQhv3YhiJ98 The Uncertainty Principle: http://youtu.be/skPI-BhohR8 Spacetime Diagrams: http://youtu.be/c0NuaATdzDE What the HECK is Light?! http://youtu.be/m2-UJAEJzcc ________________________________ SCIENCE ASYLUM STUFF Support us on Patreon: http://www.patreon.com/ScienceAsylum Advanced Theoretical Physics (eBook): https://gumroad.com/l/ubSc Merchandise: https://www.scienceasylum.com More videos at: http://www.youtube.com/TheScienceAsylum Facebook: http://www.facebook.com/ScienceAsylum Twitter: @nicklucid http://twitter.com/nicklucid Instagram: @nicklucid https://instagram.com/nicklucid/ Vlog: http://www.youtube.com/TheNickLucid ________________________________ LINKS TO COMMENTS Abhijit Ghogre - Expanding Universe: https://www.youtube.com/watch?v=C9OGc-_hT0s&lc=z13bxhdqovynhtbne22xixlh4uuojdrm1 Przemyslaw Szymusik - Sky Motion: https://www.youtube.com/watch?v=KAmmb-4Ov40&lc=z13bt3w4mlquxdef422ocbviuzafgphkj ________________________________ EXTRA INFO LINKS Logrithmic Universe Image: Pablo Carlos Budassi [Unmismoobjetivo] https://commons.wikimedia.org/wiki/File:Observable_universe_logarithmic_illustration.png Veritasium and Vsauce on Randomness: https://youtu.be/sMb00lz-IfE https://youtu.be/9rIy0xY99a0 Entropy: https://en.wikipedia.org/wiki/Entropy_(statistical_thermodynamics) https://en.wikipedia.org/wiki/Second_law_of_thermodynamics https://en.wikipedia.org/wiki/History_of_entropy https://en.wikipedia.org/wiki/Statistical_mechanics Speed of Information: https://en.wikipedia.org/wiki/Physical_information https://en.wikipedia.org/wiki/Faster-than-light https://en.wikipedia.org/wiki/Speed_of_light http://math.ucr.edu/home/baez/physics/Relativity/SpeedOfLight/measure_c.html https://en.wikipedia.org/wiki/Speed_of_gravity https://en.wikipedia.org/wiki/R%C3%B8mer%27s_determination_of_the_speed_of_light https://en.wikipedia.org/wiki/Christiaan_Huygens#Optics Information Theory: https://en.wikipedia.org/wiki/Information https://en.wikipedia.org/wiki/Information_theory https://en.wikipedia.org/wiki/History_of_information_theory https://en.wikipedia.org/wiki/Entropy_in_thermodynamics_and_information_theory https://en.wikipedia.org/wiki/Entropy_(information_theory) 1948 Paper(s) on Information: https://en.wikipedia.org/wiki/A_Mathematical_Theory_of_Communication http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=6773024 http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=6773067 Astronomy: https://en.wikipedia.org/wiki/Betelgeuse https://en.wikipedia.org/wiki/Andromeda_Galaxy https://en.wikipedia.org/wiki/Great_Debate_(astronomy) Star Chart by Dan Bruton http://www.midnightkite.com/ History of Photography: https://en.wikipedia.org/wiki/History_of_photography ________________________________ IMAGE CREDITS Logo designed by: Ben Sharef Stock Photos and Clipart - Wikimedia Commons http://commons.wikimedia.org/wiki/Main_Page - Openclipart http://openclipart.org/ - or I made them myself...
