should you walk or run when it039s cold
Bookmarked 456 weeks ago hi my name is henry i make minutephysics and you can support me on patreon: http:wwwpatreoncomminutephysicsis it better to walk or run when it039s cold out if you run then you have to deal with wind wind chill etc but your body generates more heat if you stay still standing or walking slowly you don039t generate as much heat but don039t deal with the wind note: the simple calculations in this video don039t very well take into account the baseline metabolic rateheat generation even at rest of humansreferencesphysics of running presentation: http:uwphysicswiscedureardonphysics20of20runningpdforiginal wind chill index formula: https:wwwamazoncomfactors-design-handbook-wesley-woodsondp0070717680the basis of wind chill paper: http:pubsainaucalgarycaarcticarctic48-4-372pdfbody surface area calculator: http:wwwcalculatornetbody-surface-area-calculatorhtmlnewtons law of cooling: https:enwikipediaorgwikinewton27s_law_of_cool |

bell039s theorem: the quantum venn diagram paradox
Bookmarked 433 weeks ago featuring 3blue1brownwatch the 2nd video on 3blue1brown here: https:wwwyoutubecomwatchv=mzrcdlre1b4support minutephysics on patreon http:wwwpatreoncomminutephysicslink to patreon supporters: http:wwwminutephysicscomsupportersthis video is about bell039s theorem one of the most fascinating results in 20th century physics even though albert einstein together with collaborators in the epr paradox paper wanted to show that quantum mechanics must be incomplete because it was nonlocal he didn039t like quotspooky action at a distancequot john bell managed to prove that any local real hidden variable theory would have to satisfy certain simple statistical properties that quantum mechanical experiments and the theory that describes them violate since then ghz and others have managed to extend the theoretical work and alain aspect performed the first bell test experiment in the late 1980sthanks to vince rubinetti for the music: https:soundcloudcomvincerubinettione-t |

max tegmark039s multiverse
Bookmarked 725 weeks ago the frontiers of physics have gradually expanded to incorporate ever more abstract and once metaphysical concepts such as a round earth invisible electromagnetic fields time slowdown at high speeds quantum superpositions curved space and black holes over the past several years the concept of a multiverse has joined this list it is grounded in well-tested theories such as relativity and quantum mechanics and it fulfills both of the basic criteria of an empirical science: it makes predictions and it can be falsified scientists have discussed as many as four distinct types of parallel universes the key question is not whether the multiverse exists but rather how many levels it has |

liquid n2 and copper tube magnetic levitation
Bookmarked 738 weeks ago there are many videos about neodymium magnet levitating or better say slowing its free falling in copper tube i decided to cool the copper with liquid nitrogenium to reduce its electrical resistance about three times and therefore increase magnet levitation and quotconductivity inertionquot effect |

the physics of flying 039space fighters039
Bookmarked 587 weeks ago the notion of the 039space fighter039 is a staple of science fiction they play key roles in some of the most enduring sci-fi universes and as it happens frequently the people behind these universes haven039t really given much of a though to how the design of a space fighter affects the way it flies and performsthere are plenty of great space fighter games and within the genre of 039spaceship039 games there are different flight models that are used - non-newtonian semi-newtonian and full newtonian with cloud imperium games releasing a detailed dev blog on their spacecraft flight mechanics i wanted to demonstrate some of the physics within kerbal space program we start out in the atmosphere to demonstrate how real world fighter planes fly since this behaviour is aped in star wars then we go to the mun and demonstrate various control systems seen in universes that support newtonian flight modelshttps:robertsspaceindustriescomcomm-linktransmission13951-flight-model-and-input-controls |
