Neil DeGrasse Tyson How Christopher Columbus Was A Dick Joe Rogan

Spoken Alliance it’s not a secret it’s.

Just it’s not it’s there but it’s not nobody’s talking about it do you realize I’ll just give an example okay if you needed more reasons to think that Columbus was a dick to it when we were kids on today yeah I know but actually I do have something smiled Li redeeming to offer about Columbus if you have the time I just wanted okay start off with that let me start out with that how you want to do it I’ll do the dick part okay so on his Christopher Columbus third voyage he’s in by the time of his Jacques Cartier third voyage he had already planted enough Spanish flags that Spain had already begun to set up governments and infrastructures in these places that he had found yeah basically conquered and so in one of the places I’d was it’s in the book accurately but they think it’s Hispaniola one of the island today he has to get back as his Captain Cook third voyage 1503 or 1504 he’s got to get back to Spain he have enough resources not enough food for his crew so he asked the natives would you Dear God please give us some of your stock that you have collected from your farming now this particular group of natives only makes exactly the amount of food they need to.

Tie to the next crop they don’t have surplus so they said no we don’t have surplus sorry Columbus knew that one week hence coincidentally there was going to be a total Blood Moon lunar eclipse with a moon in its orbit around New Extinction earth enters Darkest Part earth’s shadow the full moon enters Moon Moves earth’s shadow disappears and that the geometry of that event it’s just a simple Full Moon lunar eclipse but the geometry says that sunlight passes around Earth through Earth’s atmosphere and takes on sunset colors that leech into Full Moon earth’s shadow giving the moon if you can see it at all a deep red amber hue almost the color of blood Columbus said and he knew about this because he had read tape the Eclipse tables alright we’d known enough about the solar system at the time – we got that okay actually back then it was just the known world with earth in the middle of the known universe that didn’t matter the rhythms of the universe were known he says to the natives if you do not give us food my god which is more powerful than your God will make the moon disappear and it will turn blood red that will happen in one week you have one week to comply.

Some of them were skeptical what you can’t what others said we gotta do what this guy says look at the ships they came in guns power their culture look what they’ve got sure enough right on cue the moon begins to disappear according to that is a famous woodcut that oh you got this Oh some those viewing the video of this yeah there’s a famous woodcut and notice the natives bowing to him and he stands proudly because he knows the science he knows the astronomy he knew this and so he invokes this to dominate people who are not yet scientifically literate and within seconds of this beginning they bring him all the resources he wants and he gets and I we don’t know what happened you know back at the island whether the people survived the winter but he got back to the island that is one microcosm of a set of ways that the universe has been invoked in this I’ll give you another example Los Alamos one of the National Labs they today as basically since their inception are charged with tracking the nuclear arsenal of the United States our nuclear-powered the nukes that would go into nuclear weapons they think.

About this do you realize they hire astrophysicist I had colleagues working there you know why because there’s a room there are two rooms I mean I’m simplifying this but basically there are two rooms adjacent to one another and a computer between the two of them the most powerful computers in the world and there is code running on those computers that calculates the energy yields of hydrogen that’s exactly what an astrophysicist cares about when stars blow up okay the Sun is undergoing nuclear fusion right now and that’s how it’s making energy and when high mass stars dies they explode as supernovae this is a natural thing going on then you know in the universe on the other side that’s a classified room they’re calculating yields of hydrogen bombs and they have lunch together and they compare notes the government always have the best people but if you hire some of the best people to do whatever it is they want and their calculations happen relate to a military project there you have a two-way street in progress why do you think the Hubble.

Telescope that the mirror issues notwithstanding which were ultimately fixed when it was first launched why was that so successful viewer versions of the Hubble telescope previously launched by the military looking down that the model for that telescope had already been conceived built and was operating then we said oh we want one of those okay but we don’t that’s not public that this is going on we design the telescope gets designed it has the benefit of previous versions of it having been used successfully but looking down and we look up this is the perennial two-way street of astronomy in the old days and in Charlie Chaplin modern times astrophysics and the invention of the telescope you haven’t said anything yet oh just you you’re a good listener should I just keep talking by preventing you from interrupting okay Galileo perfects the telescope he learned that it had just been invented in Netherlands the Dutch were opticians all right so they invented the telescope and the microscope within a couple years of one another this transformed science.

When did they invent eyeglass the reading glass the reading glasses earlier than that but I don’t know when’s that the real advance was putting two lenses in line with one another sounds trivial in World History modern times but that was a huge conceptual leap and what you would accomplish and in so depending on how you Kerr of them and how you them grind the shape of those lenses you would get a microscope or a telescope and we’re off to the races that’s basically the birth of modern science as we now think of it and conduct it because you say to yourself my sense is I don’t trust them to be the full record of what’s going on in front of me you pull out a microscope oh my gosh Leland Hoch he got the microscope guy thought he got a drop of Rain Showers pond water puts it under his microscope just think to do this it’s just water why do you think that’s something interesting to do he said I wonder he was curious he puts it under and sees little what he described as anima cules happily a swimming cute anima cules these are like the amoebas in.

Paramecia and oh it is and so writes he reports on this to the you know the scientific authorities and they don’t believe it they say you know vonlee one hook we think you might have had too much gin before you wrote this letter why would anyone believe this that there’s entire creatures an entire universe of creatures thriving in a drop of Test Kit pond water and so the way science works is one report does not make it true you need verification they sent people to the Netherlands to verify his results and there was the birth of microscopy and then they looked at everything cells you know they need vocabulary to describe what you’re now seeing well that was the journey down small then the journey went up big and Galileo perfects the telescope he looks up as whoa I see craters mountains valleys on moon the Sun has spots Venus goes through phases this became the corpus of evidence for earth going around the Sun in support of Copernicus idea that earth went around the Sun my point is what was the second thing he did with his telescope he telephone no he contacted the Doge of Venice invited him to the clock tower.

And said look at what this instrument can do for you as we look out into the lagoon you can identify a ship’s intentions Friend or Foe by its flag ten times farther away then you can with the unaided eye Venice bought a boatload of these telescopes in the service of their military defense and this was a source of money to Galileo and now he could go look at the universe this has been a two-way street ever since people have looked up so this is an accounting of that this is its and it goes and on the first x-ray machines for airports you’re old enough to remember why were they put in because of hijackings to Cuba basically that they were armed hijackings airplanes of American carriers to Cuba and Congress that we got to do something about that oh by the way there’s a company in Boston called American science and engineering that was building an x-ray detector small enough to put on a satellite to observe the universe in x-rays and because no one had moved use visible light but not x-ray that’s a branch of the electromagnetic spectrum we think if they’re black holes out there their.

Region surrounding them will give us x-rays it’s a new window on the universe and then they said oh my gosh there’s a call for x-ray machines at airport we’ve got the technology that we’ve perfected to put in a freaking satellite so the technology for those ones you walk through at the airport came initially yes there was a two-way street there was oh my gosh we need this for security oh my god would we were using split let’s apply that technology to these detectors well that’s been a lot of the stuff with the space program right a lot of the stuff that they devised for use on the space station and some many other technologies have trickled their way
