"Weather dot com. This website allows you to follow all things that are in the space weather category. So instead of being whether that we're used to with clouds and rain and things like that this essentially means it's anything that's related to interactions between the sun and the earth it also includes other celestial objects like asteroids that are near the earth on this site you can monitor solar activity which includes things like sunspots and solar flares solar flares which are intense bursts of radiation coming from the release of magnetic energy does associated with sunspots are often accompanied by something called a coronal mass ejection which is huge expulsion of plasma and meg and magnetic field that is coming from the sun's corona billions of tons of high energy particles that carry an embedded magnetic field travel outwards from the sun at speeds ranging from two hundred and fifty kilometers per second all the way up to as fast as nearly three thousand kilometers per second when the coronal mass ejection hits the earth's magnetic field that causes geomagnetic storms which range in levels one through four much. We have categories of hurricanes and levels reinforce affects satellites which can then disrupt navigation systems like gps and other problems like even taking down power grits. however it's no bad gio storms also mean more excited ions are upper atmosphere which means the northern lights are especially gorgeous can also get updates on meteor showers and another section which is on potentially hazardous asteroids geeks. I was really surprised that of today. There are two thousand two hundred and six known potentially hazardous asteroids. So you might want to learn about those two and if you want to go to space weather dot com we look in two thousand asteroids headed our way but the likes lights nicole thinking look really cool explode. Oh my god. I was really excited to. Maybe that's good for being released on roughly. Dod las margaritas. God no i mean you can go and you can see that they're not gonna hit. Oh moscow at least fifteen hundred. No.
Untangling the Crossed Wires of China's 'Super Grid'
"Alternative explanation the bears noting but has received little discussion. So far is the continued. Integration of the chinese grit as china developed its energy resources and became the largest builder of energy infrastructure over the last few decades. It developed an extremely unbalanced grid with enormous mismatches between supply and demand. China's scale and varied geography energy. Grid meant that extremely abundant energy resources were being produced in remote locations where there simply wasn't demand for them. In northern provinces huge amounts of power from coal and wind and solar went on consumed in the southern provinces abundant hydro resources far exceeded local demand. The major operation centers in china are mostly along the southern and eastern coast thousands of miles away from the most abundant and cheap sources of energy as a consequence trying to become the world's capital of energy curtailment as described by ohm's law. Electricity simply doesn't travel. Well it standard voltages and so must be produced relatively close to load centers when there isn't local demand for energy it goes unused so in two thousand sixteen. Two thousand seventeen china was tailing effectively. Wasting extreme amounts of power in two thousand seventeen chinese curtailment from hydropower. Reach fifty five terawatt hours a figure equivalent to the entire energy output of the country switzerland in two thousand sixteen china curtailed. Another fifty two point two terawatt hours of wind and solar there simply was insufficient local demand to consume this abundance of energy leading authorities to rethink the grids design. Starting in two thousand. Ten china has been constructing an ambitious continent spanning ultra high voltage power transmission network to transmit power from remote regions with abundant energy to load centers. Balancing the grid today. Forty thousand kilometers of high-voltage transmission exists with the longest line stretching over three thousand kilometers. Much has been made of the chinese. Communist party's ambitions or general aversion to freedom tech like bitcoin in justifying the mining ban. Less has been said about the fact that the presence of minors in china was always contingent on the availability of stranded energy. The central and regional government had hitherto tolerated the monetization of excess energy. Because it simply wasn't being put to alternative economic us but as the grid integration and load balancing has improved in the last five years. Bitcoin miners have increasingly begun to compete with other industrial and commercial uses

"Were you know running the vietnam war for a long time. There's no obvious idea that. Because if kennedy had been robert kennedy. Bobby kennedy had been elected. He would have gotten us out of vietnam. Politicians are tricky. They say things and they don't end up doing them all the time. So i don't know enough about that era to say how devoted or how influential he would have been actually make that happen. And as far as watergate is concerned watergate was an example of agree gio abuse of power illegal actions on the part of the president but it also led to reforms of the system. You know the ability to have special prosecutors and things like that so maybe it would have been worse overall. If watergate had not happened if i were to imagine ideal histories i would have wanted to stop some terrible massacres tragedies genocides right like the holocaust or various other terrible things that happened. There is a little bit more cut and dried to me that if that had not happened the world would be better on the other hand. I don't know like if it comes to either assassinating or not assassinating one person. I'm not what not at all sure. What would need to happen to guarantee that the holocaust would not have happened. Yeah you can say will kill baby hitler. That's the usual thing to say but it's not at all obvious to me that the social forces wouldn't have led to something more or less similar to what actually happened in world war two. I don't know maybe they wouldn't. But i just don't know claudio slam says about a moua the interstellar visitor. We had that. We talked about with envelope while his speed was notably high for solar system standards twenty six point three kilometers per second relative to the sun. It's still very low. Compared to the speed of light would we have noticed anything weird had the movie was dash been a hundred thousand times faster. Is it conceivable that a material object can be accelerated to relativistic speeds by accession of pushes from stars or other massive bodies so it certainly would have been much weirder if a who's been one hundred thousand times faster so if you think about what is going on in our galaxy the stars moving around and you know with respect to each other and around the center of the galaxy the typical speed you should have in mind is something like a couple hundred kilometers per second okay. Two hundred kilometers per second three hundred kilometers per second something like that. That's the typical speed that stars and other objects have in the galaxy. So that's the speed. You expect everything to have with respect to everything else on average okay. This is why we made the point. That in some sense move. Speed is anomalous. Low twenty six kilometers per second is lower than three hundred kilometers per second but if it had been three thousand kilometers per second that will be an all mostly high and that would be weird. So yes that would be weird. Is it conceivable that something could actually be celebrated that fast. You know it's conceivable but it's very very unlikely Things do get pushed around by passing by stars but it happens slowly and gradually An every little pushes very tiny and sometimes the pushes go in opposite directions from each other right so you certainly do not expect things to be accelerated to very very fast speeds and i should go further than that. You certainly don't expect things to be accelerated to relativistic speeds near the speed of light. Because once they're accelerated to the escape velocity of the galaxy. They escape from the galaxy and they're no longer being accelerated by a gravitational assists from nearby stars. And things like that so there is an upper limit to speeds you expect for things that are galaxy namely the escape velocity. That is fair in christie's says a priority question. You guys are using up your priority questions..

"Than a thousand additional stars are also being formed in the surrounding molecular gessen dust clouds. It's also one of the youngest known causes with an age. Of just a million years the cloud of interstellar material which form the nebula is. Roughly forty light is in amateur and contains at least thirty thousand solar masses the triffid nebula messier. Twenty is another lot. Stuff warming emission nebula containing many young hot stars a candidate between two thousand and nine thousand light years away. The triffid nebula is that. I haven't of around fifty lie is the outside of the triffid is a bluish reflection nebula all the inner agent. Close pink thanks to ionized hydrogen. There are also to doc bands dividing the triffid nebula into three regions lobes. Hydrogen in the nebula is being ionized by central triple star system which formed at the intersection of the two doc bands creating its characteristic pink cancer another staff when we region in this part of the sky is six five five nine like added some five thousand light years away again containing both red mission and blue reflection regions now. The gripping of these three nabulsi lagoon nebula triffid nebula and six five nine is known as the secretary secretaries triplet another object with looking out for is the red spider nebula.

"Astronomers have discovered a wolf rate star system making enough material to produce a planet the size of the earth every year. The secrets of this amazing star system reported in the physical jill uncovered through two decades of painstaking observations using some of the world's biggest optical telescopes wolf-rayet it's a massive stars at an advanced stage of stellar evolution and losing material at very high rate. They thought to have evolved from special type of blue stars which have lost their hydrogen envelopes to reveal an exposed helium core wolf rates. It's usually have masses more than twenty five times that of the sun with surface. Temperatures of over twenty five thousand kelvin and up to a million times the sun's luminosity they generate very powerful still. A wins thought to be driven by intense radiation pressure and ejecting as much mask the sun. Every hundred thousand years at speeds of three thousand kilometers per second only a few hundred will fray. It's ever been identified. Most hidden cocooned inside the massive dust. Clouds they produce wolf rates can be subdivided into two main groups. Wfan stars which have spectra dominated by helium and notch agenda emission lines but can also contain some cabin and w stars which had dominated by helium carbon and oxygen emission. Lines and lack any spectra finnegan. Observations suggest that about half of all wolf-rayet stars occur in binary systems. It's thought their partners would either be another wolf-rayet star or a more evolved compact companion such as a stellar mass black hole neutron star and their ultimate demise takkula as they lives concluding in either a type one or type one c supernova explosion the authors avow study. Use the observatory the subaru telescope. And the jimmy observatory all on monaco in hawaii to capture images of nearly foam dust streaming from a massive battery star system code wolf-rayet or wr. One twelve wwl one tool is composed of a wolf. Ray it staff with a companion. That's also much more massive than the sun. the authors sequence of images included observations using the cake observatories high-resolution thermal infrared long wavelength spectrometer. It shows the system moving over time with the two stars orbiting around each other repaired twenty years causing the appearance of a spiral rotation the authors found. The dust is forming in the region with a stellar winds from these two stars interacts. Win the two. Stellar winds collide. They generate turbulence releasing huge amounts of shock guests x rays and condensing out copious amounts of carbon based aerosol dust particles. The study's lead author ryan lau from japan. Aerospace exploration agency. Jackson says the wwl one twelve systems incredibly hot luminous very fast stellar winds ejecting material at high velocities of thousands of kilometers per second lowering. Colleagues follow the decades long evolution of the dust. Nebula around w i want twelve. They expected the dust to incinerate birth because of the intense radiation of heat and the final wins but it survives. Despite the extreme environment well similar binary dust formation has been seen in other systems the dusty nebula around wwl one twelve is far more complex previous observations of the system by lao using the very large telescope back in twenty sixteen led him to believe that the dusty nebula wasn't moving but the new observations have revealed that the dusty show definitely has moved since the previous observations and as he looked through the data it became apparent that the dust spiral was actually tumbling towards the earth and observation lady confirmed by modeling says the revised observations of wwl one twelve allowed him to determine. Just how much does. The system was producing. So there is that we have the objects that we're looking at are called wolfe's stars. This is a type of massive evolve star So these evolved from stars that are over twenty times the mass of our sun that only are they twenty times more massive but they're also billions of times more luminous than the sun so these are some of the most extreme stars that we know of so this particular star is called. Wr won twelve. So the wer stands for wolf ate. This is particularly interesting will phrase star because it's forming dust so the reason why this is so unusual is because like i mentioned The stars are very luminous the very hot and they also have very fast what are called stellar winds so the rejecting materials at very high losses over thousands of kilometers second so the fact that we see dust which condenses in very cool environments is actually quite a big mystery so this is why we are interested in this particular object of went twelve. We have over. We have around twenty years of observations of this target And what it actually shows is this beautiful spiral rotation motion Which was really quite surprising to us. So the oh star. The companion star is the one that's indebted in this reddish orange spiral dust shock cone and in the one outside of that is the wolf race star. That's the hot massive star so this is the orbiting each other on timescales of about twenty years. And that's that orbital motion is actually what's causing the appearance of this spiral this three dimensional spiral the direction the viewing angle that we have towards this system is not face on is actually closer to edge on meeting as the orbit instead of looking like they're spiraling around each other you actually turn it a little bit more. So it's aligned with our line of sight and because of that it will affect the morphology or the appearance of this. Dust shock cone That's forming so this spiral dust cone will look very different depending on how reviewing it and the system debris went twelve produces a lot of dust. produces around in earth mass of dust year which is pretty substantial on any of dust. So this has some pretty interesting implications for the origin of dust in the early universe. That's ryan lau. From the japan aerospace agency jackson and this space time still to come and the threat to earth being posed by the asteroid apotheosis and growing fees that it could take up to a year to fix the problem aboard the new orion spacecraft. All that and more still to come.

"He's a young journalist over there and he told me about the indian space programme. And how you know. They're doing sort of what we do for like pennies on the dollar now like the they exactly what it is but they put something into space for the same amount of money that it costs hollywood to make the movie. Gravity hundred billion dollars and the cheney probe was the name. it might be pronouncing it. I i don't remember. Meet him probably spoke about it. But i do not recall top ahead but like their space program is doing shit for hundreds of millions of dollars which ours can't really do anything without a few billion attached to it. You know so. They're doing whether or not it safe. You know who who knows. But they're kind of doing what we're doing just for a lot cheaper And if they can keep that up and get better and better at it and get cheaper she. It'll spur on competition. Everyone's going to have to step up their game hill. Yeah you're right break russian monopoly on on his base kennedy law. Musk future president of mars right there. I'm all for i'm all for. Oh yeah. I did have one other thing mentioned over the last week. Which was project marauder. Which is the other potential thing to be used. As normal weapons platform i think is more likely to be used either on naval ships or on say modified airbus or like Seven seven twenty seven But it is a plasma rail gun. I'm looking at it right now. So this thing can shoot a few grams of hydrogen gas At three thousand kilometers per second not meters per second kilometers per second and that was in nineteen ninety. Three out mistaken The last we heard citation about it was nineteen ninety-five before it was acquired by the department of defense classified ninety six. They were Projecting being able to reach Three percent of light speed by two thousand yes he. This is like with the seventy one blackbird like if we were so like black where we had it and then you know we decommissioned it for whatever reason you know to say we've made something better no the fuck we haven't to my knowledge anyways But yeah so. We haven't heard anything since according to this since ninety five but to think we have it made some sort of leap in this technology in. Was that twenty five years. Yeah fifteen years. Fifteen twenty five twenty five years. Do come up for getting old right shit. Yeah that's insane yo. They might have if anything they put on the backburner like let. Let's wait ten years till technologies there. I think rail guns were on the black on the back burner for a long time so we have them now. Don't we do we do we have. I don't have it on the right now but actually have a slug from a new on. Yeah s bad. yes. I'm going to be moving into a new apartment. Seems i'm gonna be going through all my old chit.

"Kareem is CO founder and CEO at Institute Kareem. Welcome back to the Tacoma area. Podcast pleasure to speak again. Absolutely so if Kareem's name sounds familiar. That's because we spoke We're trying to figure this out. It was between a year and a half a year ago The show actually was published in September. Was Number three hundred two and you should definitely check it out for Kareem's full background But croom wanted to give us a brief overview of what you're up to as well as an update from when we last spoke absolutely so I it's a pleasure to be back in. Continue our conversation on aside. He's been pretty invent follow. The Lot has happened as you know instead. Deep is a decision making a startup. So we focus on Problems related to making complex decisions We also do our own innovation and the tried to be helpful to the community and we've made progress basically on this three areas. We've been able to release innovative products. In decision making we've also been able to publish innovate in research Publishing original you know like pieces. That were actually. What come that nervous where we got the spotlight presentation for example with Google declined? And we've also been very active on the community side organizing major events in Africa and basically lots of young talents. Find say super -tunities in there and the we most recently saw one another at Nuremberg and had a chance to catch up briefly at the black dinner where you really piqued my interest around one of the company's new initiatives or products which is called DP. Cb tell us about what is absolutely so this'll be actually started with with conversation Two years ago I I had a dinner with a good friend of mine. Who is actually an expert in hardware design worked on like no chips for a well known phones etc and we were speaking about like. What is he doing this particular sector? And he was like not that much like particular like busy stunt for printed circuit boards so basically those ships that you will find with all sorts of Consumer Electronics Products Iphones Speakers Bluetooth etc and You know the situation in that market was that auto routers basically automated systems to connect the different components like built. Basically the electrical secretary have been going on for many years but they were not that make and we were like. Hey that sounds like an interesting problem to to look at. We started looking into it eventually. This good front now. Be True was now meeting or hardware team joint steady and we've worked very hard on this project and we're very proud to have been able to achieve goals and in November last year we've released it in. Beta form and it is a world first for the first time we have a system that is end to end fully deployable and scalable on the cloud capable of understanding how to route chips essential and now last time we spoke we. Our conversation was focused on the work. Your company was doing applying reinforcement learning to logistics is deep be also based on reinforcement learning absolutely and this is a very strong commonality and like design philosophy between or or products. So in a sense. Let me give you an example. We've we've continued to do great work in logistics and the recently last September. We've won a major contract for example with that. Chaban the German railway company and to give idea this is about routing trains on a large scale talking about ten thousand trains a day and some think on some thirty three thousand kilometers of railway but downs out their communities between routing trains and routing chips on a board and so we realized that the projects and the type of research that study is doing is actually applicable to multiple fields. And when it comes to imbed Ziegler printed circuit boards. They're putting compelling so. We went full speed ahead and this turned out to be office product. Alrighty so when you initially met with your friend your mention that they're you know while this these auto routers have been in place or have been in use for many years. They were not without their challenges and problems. What were some of those challenges and problems? And what was the opportunity to introduce? A I think Reuters have been the they've been. There's been a lot of great work. Donald Reuters but in terms of like design philosophy. The design philosophy is all about essentially using ristic's to solve problems and we spoke a little bit about this in Bester conversation so it's very similar to let's say what was the status of software for chess before out. Fazio came out the systems which were very well actually but still are built on your way. Sticks fought for the hardest problems. Ristic's have limits and a system that can essentially mobilize learning can. Learning get scale can get better results when it comes in particular for in the status of printed circuit. Boards it is actually incredible and we are in twenty twenty that actually complex sucrets still designed manually and the reason why people design those Mandy is because auto routers essentially a failed to deliver the goods to the degree of quality which is expected by high quality customers so we see a really compelling opportunity with modern built on the latest innovation. Some of it actually developed in house we actually have patents on the work done for the. There is an opportunity to accelerate the design cycle of products. Because it's not just about quality you mean. Engineers do absolutely amazing work and have amazing intuition. It's about the speed. Human engineer could take in certain cases multiple weeks if not months to completely root complex with more than we do believe instead that this timing can be proud to twenty four hours this if done at scale it would be tremendous for the industry and it would accelerate the product cycle. We are using consumer electronics to have a cycle every six months of the year. There's a new version coming. We believe that any I could actually accelerate A. That's that's a that psycho and as a consequence also make it easier to design new products and experiment and ultimately unleash more human creativity and mobilizing gay. You mentioned complexity of the boards as being one of the challenges. What are we talking about when we talk about complexity? We I'm assuming we're measuring that in for example number of components but having worked with circuit boards before there are also issues like the number of layers and things like that when you talk about a complex board. What exactly are you talking about? So about really consists in basically an. Kyi's that we need to connect and as a consequence like those guys they can be what needs to be connected so you have fairs of components essential get need to be connected and they could be thousands of those and as you mentioned rightly there could be multiple layers simple designs start with two or four layers that you could have a lot more and the more you have layers the more components you have to connect the heart of the problem. It is an empty heart problem and so this is where I can help. But you can you when you're looking at the most difficult designs that we take human engineers significant amount of time to solve

NASA ScienceCast 299: The Lasting Impacts of Comet Shoemaker-Levy 9
"In the lasting impacts of Comet Shoemaker Levy nine presented by science at NASA at the close the last century a comet captured into orbit around a planet traveled to close and was shredded by gravity into multiple pieces some as large as half a mile or one-kilometer-long those fragments would plunge engine to the planets atmosphere in a series of impacts. Would the impacts be spectacular or would the comet fragments disappear without a trace in July nineteen ninety-four astronomers around the world watched with bated. Breath as the fragments of Comet Shoemaker Levy nine slammed into the planet Jupiter Dr Kelly fast was one of the impacts observers and is now manager of Nasr's near Earth Object Observations Program. It was just incredible to watch such an impact event had never before been witnessed. Let alone studied ground based telescopes around the world and spacecraft like Nasr's Hubble Space Telescope and even the Galileo orbiter on route to Jupiter were used to to observe the impacts the discovery of the comment by Caroline Jeans Shoemaker and David Levy gave us about a year at a plan observations. The impacts proved to be impressive the fragments some twenty one in all plunged plunged into Jupiter's atmosphere over the course of six days at impact. They were travelling at a speed of about thirty seven miles per second or sixty kilometers per second heating the atmosphere to at least fifty three thousand degrees Fahrenheit. Fahrenheit or thirty thousand degrees Celsius like the splash from throwing a rock into a pond the impacts created giant plumes of material from Jupiter's lower atmosphere which rose as high as nineteen hundred miles or three three thousand kilometers above the cloud tops into the stratosphere in the aftermath the Plume Splash Bax scarred Jupiter's atmosphere with dark clouds of impact abry which could be seen for months as they were gradually dispersed by Jupiter's was wins so what scientists able to learn about Jupiter itself as a result of the impacts for one thing those dark clouds of impact debris acted as tracers of the winds in Jupiter stratosphere and by following their motion over.

This is monster the zodiac killer. Listen and subscribe at apple podcasts or on the iheartradio app. Welcome to brain stuff from how stuff works. Hey, brain stuff, loin, Boca bomb here light. In addition to being a bright, Patrick, sunshine on your window. Sill is a metaphor for enlightenment and exploration, which is a bit paradoxical for phenomenon that even after thousands of years of inquiries and endless experiments. Scientists still can't quite explain is it a particle or wave or both or neither do we need a new word for it. Your eyes tell you a lot about the way light behaves. It travels so fast that seems instantaneous about one hundred eighty six thousand miles or three thousand kilometers per second. It blazes through air and space and laser like straight lines. But it also bounces reflects and refraction, and when it interacts with the right medium like a camera lens, it make her we know that it's made up of tiny units that we call photons, and we know that the term waves can describe its movements. But neither of these words really encompass lights auditees in ancient times. The Greeks used philosophy to attempt to address lights wide range. Of behaviors perhaps they thought light is actually composed of little bits of stuff that bounce to and fro the idea never really caught on then in the sixteen hundreds French philosopher Rene Descartes became convinced that light was essentially a wave one that moved through a mysterious substance that he called platinum Isaac Newton thought that light was a particle, but he was at a loss for a way to explain many of its properties. Like the way it refracted and could be split by prison from a single beam of white light into a rainbow of many colors of light. This was largely before the rise of empirical studies in science wherein, we attempt to answer questions about the world around us by designing experiments that demonstrate well how stuff works back in the day. Science was a matter of philosophy people coming up with about how stuff works and basically arguing about the ideas merit to be fair. Our modern microscopes computers and other equipment help just for example, lights behavior becomes more evident, depending on where you're observing it in the vacuum of space. Ace light zips along at the aforementioned one hundred eighty six thousand miles or three hundred thousand kilometers per second. But point a beam of light at a very dense bit a matter say a diamond, and it can slow to only around seventy seven thousand miles or one hundred twenty four thousand kilometers per second much easier to observe relatively to try to explain in. These are modern times. What light is let's I remember some science basics waves are not a thing or substance. They're a property of thing. A wave is a compressing and stretching of a particular medium, a like an ocean wave that drives toward the shore or the ripple spreads out across the surface of a pond when you toss in Iraq, you can see the waves with your eyes feel them with your body. And sometimes when a sound wave happens in the air, you can hear them with your ears particles on the other hand are not quite so easy to define particle can be a tiny bit of matter. A matter broken down into its smallest and most basic units water, for example, is made up of countless party. Guls particles that are affected by waves. What's really happening when you watch a wave in the ocean or ripple in a pond is that each particle or molecule in this case of water is being moved and thus the medium of the ocean or pond is being compressed and stretched in sequence and we see waves, but light as experiments have proven also consists of particles that we call photons the behave like waves. Let's unpack that there was a famous nineteenth century double slit experiment in which researchers beamed light through two slits and observed the way the light struck a screen behind the slits what they saw was that the streams of light affected each other like two hands splashing water in the same sink as if they were waves interfering with one another. But then in the twentieth century scientists began their pioneering explorations into subatomic particles. Like neutrons electrons, Albert Einstein wondered what would happen? If you emitted light one photon at a time in the double slit experiment. What scientists saw dumb found? Did them the single photons went individually through the slits, but the way that they struck the screen over time showed the same interference pattern that occurred with full-scale beams of light streaming through both slits this behavior can't be explained by the physics. We use to describe particles and waves in the macro world around us, it's in the realm of quantum mechanics. The physics theories that describe what goes on at the very smallest subatomic levels, and which we humans still don't really understand. So ultimately, if you want to answer the question, what is light you could call it both a particle and wave and you'd be correct. But as for fully explaining why and how it works. We're still working on it.
What Is Light?
"Light. In addition to being a bright, Patrick, sunshine on your window. Sill is a metaphor for enlightenment and exploration, which is a bit paradoxical for phenomenon that even after thousands of years of inquiries and endless experiments. Scientists still can't quite explain is it a particle or wave or both or neither do we need a new word for it. Your eyes tell you a lot about the way light behaves. It travels so fast that seems instantaneous about one hundred eighty six thousand miles or three thousand kilometers per second. It blazes through air and space and laser like straight lines. But it also bounces reflects and refraction, and when it interacts with the right medium like a camera lens, it make her we know that it's made up of tiny units that we call photons, and we know that the term waves can describe its movements. But neither of these words really encompass lights auditees in ancient times. The Greeks used philosophy to attempt to address lights wide range. Of behaviors perhaps they thought light is actually composed of little bits of stuff that bounce to and fro the idea never really caught on then in the sixteen hundreds French philosopher Rene Descartes became convinced that light was essentially a wave one that moved through a mysterious substance that he called platinum Isaac Newton thought that light was a particle, but he was at a loss for a way to explain many of its properties. Like the way it refracted and could be split by prison from a single beam of white light into a rainbow of many colors of light. This was largely before the rise of empirical studies in science wherein, we attempt to answer questions about the world around us by designing experiments that demonstrate well how stuff works back in the day. Science was a matter of philosophy people coming up with about how stuff works and basically arguing about the ideas merit to be fair. Our modern microscopes computers and other equipment help just for example, lights behavior becomes more evident, depending on where you're observing it in the vacuum of space. Ace light zips along at the aforementioned one hundred eighty six thousand miles or three hundred thousand kilometers per second. But point a beam of light at a very dense bit a matter say a diamond, and it can slow to only around seventy seven thousand miles or one hundred twenty four thousand kilometers per second much easier to observe relatively to try to explain in. These are modern times. What light is let's I remember some science basics waves are not a thing or substance. They're a property of thing. A wave is a compressing and stretching of a particular medium, a like an ocean wave that drives toward the shore or the ripple spreads out across the surface of a pond when you toss in Iraq, you can see the waves with your eyes feel them with your body. And sometimes when a sound wave happens in the air, you can hear them with your ears particles on the other hand are not quite so easy to define particle can be a tiny bit of matter.
