to see you with somebody new Oh I, never thought I’d be happy With somebody else, cause now you’re more yourself to see you do the things we do never thought I’d be happy to see you with somebody new never thought I’d be happy to see you with somebody new Oh I, never thought I’d be happy With somebody else, cause now you’re more yourself never thought I’d be happy I never thought I’d be happy Dancing with another, It’s better like that it’s clear we’re good without each other Wide awake and dreaming, I wanted you back So many nights of barely sleeping to see you with somebody new Oh I, never thought I’d be happy With somebody else, cause now you’re more yourself to see you do the things we do never thought I’d be happy to see you with somebody new I never thought I’d be happy I guess that’s how I know I’ve finally let you go Should hurt, somehow it don’t You’re holding someone close But it’s good to see you loved, let’s call it even I used to wish you would never find the one Just to get you out my mind for an evening Spent all my weekends pretending I was fine Never thought I’d be happy Never thought I’d be happy to see you with somebody new Oh I, never thought I’d be happy With somebody else, cause now you’re more yourself to see you do the things we do never thought I’d be happy to see you with somebody new I never thought I’d be happy I guess that’s how I know I’ve finally let you go Should hurt, somehow it don’t You’re holding someone close And I wonder how you’ve been without it It’s been a year since you gave me back my love But there’s something kinda nice about it I didn’t think that I’d see you here tonight

Waves: Light, Sound, and the nature of Reality

Waves: Light, Sound, and the nature of Reality


Light is a wave of electric and magnetic fields. Sound is a wave of air pressure. According to Quantum Mechanics, all the particles in the universe have the properties of waves, including all the particles that we ourselves are made from. Therefore, to understand light, sound, and the very nature of reality, it is necessary to first understand waves. To understand the properties that all waves have in common, consider a wave travelling along a rope. The wave transmits energy and can encode information. Yet each individual atom stays pretty much in the same spot. When a wave reaches the end of the rope, the wave and its energy are reflected back. If the end of the rope is fixed and can’t move, the reflected wave is flipped upside down. If two waves collide, they pass right through each other. When the two waves are on top of each other, they can momentarily cancel each other out. When the two waves are on top of each other, they can also momentarily strengthen one another. Here, the two waves strengthen each other where they intersect. Now, suppose we have more than two waves. Now, suppose we have an infinite number of waves. This wave is composed of an infinite number of waves that spread out in all directions. When added together, they form a wave that travels in just one direction. Let’s consider what happens when this wave hits a barrier with a small hole. The waves behind the barrier are blocked. Only the wave behind the hole passes through. Since this wave no longer has the other waves to combine with, there is now nothing stopping it from spreading out in all directions. This is the reason why waves spread out when they pass through a small hole. Now suppose the hole is bigger. If the hole is bigger, then more of the waves are able to pass through. If the hole is small, the wave spreads out in all directions. If the hole is bigger, most of the wave keeps moving forward without spreading out. To understand why this happens, consider the pattern that forms when a wave passes through a large hole. The waves going to the sides often cancel each other out, whereas the portion of the waves going forward always strengthen each other. However, if the distance between the incoming wave peaks is much larger than the length of the hole, then the waves that pass through the hole strengthen each other in all directions. The wave spreads out when the distance between the wave peaks is much larger than the length of the hole. If the distance between the wave peaks is much smaller than the length of the hole, then the wave moves forward without spreading out. For this same reason, if the distance between the wave peaks is much smaller than the size of an object, the object will block the waves. But, if the distance between the wave peaks is much larger than the size of an object, the waves will go around the object. In the case of sound waves, the distance between the wave peaks is much larger than most objects we deal with. Sound waves can therefore go around most objects. In the case of light waves, the distance between the wave peaks is much smaller than most objects we deal with. Most objects therefore block the passage of light waves. This is the reason why we can hear things even if there is an obstacle in the way… But we can’t see things if there is an obstacle in the way. Some materials allow light waves to pass through. Although the speed of light through empty space is the same to all observers, light slows down when it passes through certain materials. The image is distorted because when a wave passes into a material where its speed is different, it changes direction. To understand why waves change direction when they enter a material where their speed changes, consider the following. If a wave enters the new material at a 90 degree angle, then it will continue moving in the same direction as before. If the wave enters at a different angle, then the left side of the wave will enter the material at a different time than the right side. White light is composed of all the different colors combined together. Each color of light is an electromagnetic wave with a slightly different frequency. In some materials, the speed of the wave does not depend on the wave’s frequency. In other materials, the speed of the wave does depend on the wave’s frequency. If white light enters this type of material, each color will bend at a different angle, causing the colors to separate in different directions. This is why sunlight passing into rain droplets can create a rainbow. Consider a case where the speed in the material we are entering is significantly faster than in the material we are leaving. If the angle is shallow enough, there will be a total reflection of the wave. This is how light stays inside fiber optic cables. Although waves sometime reflect completely, there is always at least some reflection every time a wave transitions into a material where the speed is different. The greater the difference of the speed in the two materials, the greater the reflection. If the material we are entering has a lower speed than the material we are leaving, the reflected wave is flipped upside down. If we have more than one boundary, then there will be a separate reflection at each boundary. In the case of light waves, these types of double reflections occur at the surface of air bubbles, and on thin films of oil floating on water. The two reflected waves can either strengthen each other or cancel each other out, depending on the frequency of the light and the distance between the two boundaries. Since the thickness of the bubble’s surface varies from one spot to another, different spots on the bubble will have different frequencies of light strengthen each other or cancel each other out. This is why bubbles and thin films of oil sometimes have a rainbow appearance. If a wave is fixed at two points, it can vibrate like this. If it has more energy, it can instead vibrate like this. With even more energy, it can vibrate like this. Or like this. According to Quantum Mechanics, all particles are described by waves. The wave describes the probability of where the particle is located. If the particle is given more energy, the wave will look like this. As the particle loses energy to the surroundings, the wave changes. The probability of a particle being at a particular location depends on the wave’s amplitude at that location. This means that in this case, the particle has a zero probability of being in middle area where the wave’s amplitude is zero. The particle somehow transitions from one side of the box to the other, without ever crossing the boundary in between. This means that this is not an accurate representation of how the particle is moving, and there is no accurate representation. Let’s try to represent the particle moving in a different direction. As before, how the wave looks depends on the particle’s energy. Now let’s try to represent the particle moving in both directions. The wave describing the particle now oscillates in both dimensions. How the wave looks depends on how much energy the particle has in each direction. Now suppose that instead of moving in two dimensions, the particle is moving in all three dimensions. And instead of being bound inside a square box, it is bound by the charge of the nucleus of an atom. As before, there are a number of possible waves that can describe the probability of where the particle is located. These possible waves are what we call the electron orbitals of an atom. Each orbital corresponds to a specific amount of energy for the particle. All the atoms and particles in the universe behave this way, including all the atoms that we ourselves are made of. Waves are at the very heart of the nature of reality.

What Do Stars Sound Like? | Space Time


Thanks to brilliant org for supporting PBS Digital Studios Twinkle twinkle little star how I wonder about your interior structure and dynamical properties Believe it or not we can now map the interiors of stars by Listening to their harmonies as they vibrate with seismic waves Stars are among the best understood objects in astrophysics This is impressive given the fact that they are impossibly distant opaque balls of fiery plasma yet mathematical models emerged in the early 1900’s that describe the balance between the gravitational crush and the outward flow of energy from the fusion reactions in the core these equations of hydrostatic equilibrium Allow us to calculate things like the density and temperature of the core the way energy flows to the surface And even the lifespan of stars these models are largely built around what little we can learn from the light We receive directly from the surface of stars But how do we test these models if we can never see beneath those surfaces? Well we may not see light from beneath the stellar surface But another type of wave travels freely through stars. I’m talking about seismic waves see stars have a dynamical complexity far exceeding the simplest predictions of the equations describing stellar structure they Resonate vast waves reflect around the stellar interior setting up global oscillations natural resonant frequencies that carry information about stars impenetrable interiors Stars ring like bells and although we can’t hear this resonant vibration directly We can see its effect in the changing brightness and the motion of the stellar surface the fast-growing field of astro Seismology uses these oscillations to probe the interiors of the distant stars When we try to understand other stars we always start with our Sun, while the distance does are infinitesimal points of light – even our best telescopes the surface of the Sun can be resolved in incredible detail The effects of seismic activity can be mapped across its surface understanding asteroseismology starts with understanding helioseismology actually back up understanding helioseismology starts with regular old seismology on earth Geo seismology on earth seismic waves are generated by earthquakes and can travel around the planet as longitudinal pressure or P waves Transverse shear or S Waves and surface waves which are a mixture of P And S Waves stars also support P waves and these are true sound waves that echo around their interiors Because stars are fluid rather than solid they don’t support shear waves however they do support two types of gravity waves Now these are not gravitational waves gravity waves result from the restoration of gravitational equilibrium When some material is moved from its preferred depth buoyancy forces try to push it back into place In stars these waves occur below the surface G Waves and on the surface F waves the latter are Closely analogous to ocean surface waves on the earth however It’s the pressure waves the P waves that really dominate in stars like the Sun These acoustic waves are generated by turbulence just below the surface of a star just as seismic waves on earth are created by earthquakes just below the surface in the lithosphere They start as traveling waves that can move throughout the stars in a structure however Just as a single tap con set an entire bell ringing, a single traveling wave feeds its energy into Standing pressure waves that cause the entire star to vibrate These P mode oscillations follow the rules of spherical harmonics Taking the form of regular patterns of density oscillations Throughout the star the distribution of the pan depends on the frequency or the mode much like on the skin of a drum Many modes vibrate at once overlapping in a complex structure of resonance the strongest oscillations in the Sun are in the 2 to 4 mhz range These are the suns 5-minute oscillations, so What does this look like? well for the Sun we can map these oscillations in two ways changes in brightness and changes in velocity brightness of spectral lines in the sun’s atmosphere Can change by around 1 part per million over the course of an oscillation? At the same time gas moves vertically in and out during the same oscillation reaching velocities of 0.1 m/s this can be detected in the Doppler shift of spectral lines and because many different modes overlap the complex overlapping effects of these oscillations are separated using Fourier analysis We’ve spoken in depth about Fourier analysis in our recent episode on understanding the uncertainty principle So I won’t go into too much detail here, in short the many overlapping modes form complex oscillations on the surface of the star But these can be deconstructed into simple sinusoidal oscillations each of which corresponds to an individual mode resonating throughout the star Hélio and asteroseismology are all about determining and modeling the resonant modes within a star See the nature of these modes depends on the internal structure specifically on how the speed of sound Changes throughout the star, which in turn depends on the stratification of temperature density and Composition The internal rotation of the star is also a key factor Helioseismology has allowed us to verify and improve the models of the sun’s internal structure It’s also revealed new things for example that the inner radiative zone rotates almost like a solid ball while the outer convective zone rotates at different speeds depending on latitude this differential rotation Powers the sun’s magnetic field and is also responsible for twisting that magnetic field to drive the sunspot cycle Helioseismology has also allowed us to measure the composition of the core Which tells us how much of the sun’s hydrogen fuel source has already been burned into helium In this way it’s been revealed that our Sun is currently around halfway through, its 10 billion year life span Which is consistent with h dating of the oldest meteorites? observations of the Sun surface are relatively easy seismological studies of distant stars asteroseismology Is much more difficult, they’re too far away to resolve their surfaces So we only see the global effects of their oscillations. The Doppler shifts due to local gas moving are completely washed out however, There is global flickering tiny changes in overall brightness that can allow us to figure out the strongest resonant modes Those modes allow us to determine fundamental properties like radius mass density and surface gravity in red giant stars Asteroseismology has been used to determine the fusion activity in their dying cause Allowing us to learn just how close these stars are to their last flicker But astro seismology really is hard to do to see that faint flickering we have to go to space The Canadian MOST and the French COROT satellites, pioneered this work while KEPLER does asteroseismology? mere as side gig to finding alien planets future planet hunting satellites like TESS and PLATO will continue this work with higher precision and for many more stars Most stellar seismology is focused on learning about the average global structure of stars But at least for the Sun, It’s possible to learn about current local events that are hidden from our view For example we can map the currents of plasma and density fluctuations as they shift beneath the solar surface In helioseismic holography, The visible wave field so the distribution of Doppler velocities across the visible surface of the Sun is used to infer the current state of the standing waves throughout the Sun, that includes the far side of the Sun In fact Helioseismic calligraphy is capable of detecting sunspots long before the Sun rotates them into visibility and this can give us advanced warning of potentially dangerous solar activity stars seen There harmony ISM a hidden in the flickering of their light and in the subtle in/out of their services Woven into that music is knowledge of their mysterious depths and of their pasts and futures We’re only now learning to decipher the complex overlay of tones in stellar oscillations. We’re learning the lyrics Twinkle twinkle little star and in doing so you give up your secrets because the science of asteroseismology Can now translate the messages of stars twinkling at us from across space-time.

Eventually happen as the Sun wanders the galaxy and encounters new neighbors But it’s still spectacularly unlikely. Dimitri Also asks, whether being in a different spot in our orbit can save us from a gamma-ray burst Well the answer is no Nowhere is safe Geo beams from exploding stars are estimated to have jets with conical opening angles of between 2 and 20 degrees But even if a super focused one degree gamma-ray burst hit us from a single light year away That jet would have diverged to something like 10 times the size of our solar system by the time it reaches us it would hit the whole solar system equally Luna asks whether building underground cities would help against a gamma-ray burst, well I’m sure they’d protect us against the follow-up effects of increased UV But so does hats and sunscreen however, none of these would protect the rest of the biosphere on which we’re still rather dependent Felix scneider asks how electromagnetic radiation can be focused by a magnetic field Now this is an excellent question As Felix realizes light is not electrically charged and so isn’t affected by em fields in fact the magnetic field of a gamma-ray burst focuses charged particles electrons and the nuclei of the exploding star those particles can then fire photons in our direction in a couple of different possible ways One is synchrotron radiation The charged particles spiral around the axial magnetic fields and emit photons as they do The other is inverse Compton scattering particles in the jet bumpy two existing photons perhaps synchrotron photons and scatter them to higher energies and Preferentially in the direction of the flow, in both cases photons are emitted in different directions but an effect called relativistic beaming massively amplifies our perceived brightness of the light emitted in the same direction as the near light speed charged particles of the jet Upcycled electronics suggest that I spoil the Ordovician Silurian extinction script from PBS eons Ridiculous if I’d stolen it from eons it would have been really good check it out PBS eons It’s really good

One part of music’s soul: physics

One part of music’s soul: physics


Welcome to BrainSnacks! Have you ever asked yourself what music
actually is? I mean in terms of physics. I don’t want to ruin the romance and fun of
music of course, but the explanation how music actually works might give you
another viewpoint on it or “hear point”. Here are some music / acoustic basics. If
someone sings a tone or plays it with an instrument, the air molecules around
start oscillating. They do it in a periodical way so the oscillation can be
described with an acoustic wave. One of the most important characteristics of an
acoustic wave is its frequency. It indicates how often the wave occurs in a
certain amount of time. Also the period of a wave is important. It is the time
needed for one cycle of the wave and the relationship between the frequency and
the period is reciprocal. For example: wave 1 occurs two times in one second
and wave 2 occurs four times in one second. So wave 1 has a frequency of two
per second and a period of a half second and wave 2 has a frequency of
four per second and a period of 1/4 of a second. The unit per second is also
called Hertz. A piano has tones from approximately 16 to 5500 Hertz and the
higher the frequency the higher is the tone. Let’s listen to some cords now and
for that I asked two very talented singers to join me. Hi I’m Simon!
Hey I’m Moritz. One, two, three… But the question arising is: why do these
courts sound so good for our ears? So each tone has a different frequency and
if they’re played or sang together the acoustic waves of the single tones
influence each other and they form a new wave that is the superposition of the
single waves. Let’s look at the example of my left: the two tones are a C and an
E. This musical interval is called a third.
An acoustic wave that corresponds to a note of that C has a frequency of 132
Hertz and that E has a frequency of 165 Hertz. So the frequency of E is the
frequency of C times 5/4, that means that the superposed wave will repeat every 4
periods of C or every 5 periods of E and as you can see it has a regular pattern.
Our ears really like regular stuff so that is why it sounds so good.
It is similar with a C and a G played or sang together. The interval between these
notes is called a fifth. The frequency of G is the frequency of C times
three-halves, so the superposed wave repeats after two periods of C or three
periods of G as you can see also this pattern looks pretty regular and
therefore the two notes played together sound good. One example for a wave
pattern that it’s not so regular is that one of a tritone formed for example with a
C and an F-sharp. Aou hear immediately that it doesn’t sound so nice. The
frequency ratio of these notes is 45 to 32 that means that the pattern just
repeats every 32 periods of C or every 45 periods of F-sharp and that explains
the not so pleasant sounding interval. The cords we sang on the beginning of
this episode were major courts and they always consist of a root for the chord
a third and the fifth. The superposed waves form a regular pattern and that is
why the cord sounds good. Makes sense right? I hope you enjoyed
watching this video, this topic was completely new to me, I just studied some
theory of harmony playing the piano but I never looked at the math and physics
of it. Please let me know in the comments if you would like me to do more videos
about this topic or write an email to [email protected] . I find it
really interesting and fascinating so let me know if you share my excitement.
You can also follow BrainSnacks on Facebook, Instagram and Twitter and
the links are in the description of this video. I also want to thank Moritz and
Simon for helping me with this video, I had a lot of fun and if you want to see
more of them they have some really cool bands. Simon’s band is called Cosmo Super
and move it’s band is called Zaunkönig and the links are in the

Preview: How the Fourier Transform Works: Lecture #2 – Sound As Sine Waves (Extract)


How can something so simple like a Sine wave
be so versatile? After all we use sound to transfer information in speech or music. How
can such a simple wave like this contain so much information? Well the short answer is
that it can’t. This wave just sounds like a single tone. In this video we’re going to see and hear
what we can do to make this Sine Wave sound a little more like something you might hear
in the real world. Until now, we’ve looked at our Sine wave as
a signal that changes over time like a floating ball moving up and down on the crest of a
wave. I want to look at our wave in a slightly different way. I’m going to assume that the basic shape of
our Sine wave never changes, it always looks like a rise and fall over time. So what properties
of my wave can I change? There are, in fact, 3 properties I can change, but for now I’m
going to deal with only 2 of them, we’ll deal with the 3rd in a later Blog post. I’m going
to change the frequency (or pitch), and the amplitude (or loudness), of my wave. In the following demonstration, you can hear
how my Sine Wave rises and falls in frequency and also how it keeps getting louder and quieter
within each cycle. You can also see this on the graph too. As the wave gets higher pitch
and quieter in amplitude, the peaks and troughs of my wave bunch together and become smaller.
As the pitch falls, the wave gets louder, the peaks and troughs spread and increase
in height again. So if I already know what my basic Sine Wave
looks like, I don’t really need to see the wave itself. What interests me is its frequency
and its amplitude. So I’m going to plot my Sine Wave on a new graph. We can now see our
single Sine Wave represented as a peak. As the frequency increases, the peak moves to
the right, and as it decreases again the peak moves back to the left. As the amplitude decreases,
the peak gets smaller and as the amplitude increases again, the peak gets bigger. This new way of looking at my Sine Wave is
known as looking at it in the Frequency Domain, plotting the amplitude of my Sine Wave against
its Frequency as opposed to the way we looked at it before in the Time Domain where we plotted
how the amplitude of our Sine Wave changed over time. This distinction is going to be
very important to us later on as we get deeper into what the Fourier Transform does, but
for now I want to use the frequency domain to look at how we might change our basic single
frequency Sine wave into something more interesting, something, a little more musical. So let’s go back to the Sine Wave we had before.
Here it is in the Time Domain and here it is in the Frequency Domain. What happens now if we add another Sine wave?
You can see our new Sine wave represented in the frequency domain as a new peak to the
right of the first one meaning that it is a Sine wave with a higher frequency than the
first. The peak is smaller, telling us that it is not as loud. Now let’s look at the affect
it has had on our Sine Wave in the time domain. Now we’re going to add another Sine Wave at
another frequency, and another one, and another. Each Sine wave appears as a new peak in our
Frequency domain graph and changes the shape of the wave form in our time domain graph.
As we add more and more sine waves to our signal and begin to play a little with their
amplitudes, our wave form begins to actually sound like something real, a Cello in fact,
playing the note A.
