what are these things called? i know it's cogs and whatnot, but these look like some kind of model kit or something? would be kinda cool to have something like that to fuck around with to pass the time
Sagittarius A*. aka: the super-massive black-hole at the center of the Milky-way.
This last one I posted is the neutron star in the Crab Nebula. It's a false-color x-ray photo taken from Chandra.
This last one is a Fourier Transform, it breaks a function up into its constituent harmonics. It relates a functions frequency domain to its time domain.
This gif here shows the orbital resonance of the asteroid Chakrilo (the first asteroid discovered that has rings) with the planet Neptune. The reason why this looks strange for an orbit is because this is being displayed in a rotating reference frame.
the asteroid belt is actually a reuleaux triangle?
This is Saturn's moon Prometheus. It is on the inner boundary of Saturn's F ring. The outer boundary of the ring is shepherded by Saturn's moon Pandora (not shown). When a particle in the F ring runs too close to Pandora in its orbit it is slowed down and falls back into the F ring. When a particle in the F ring runs too close to Prometheus in its orbit it is sped up and 'kicked' back into the F ring.
These two moons, Prometheus and Pandora, are called Shepard moons by astronomers because they literally herd the ring into being stable.
Yes, Jupiter has quite the harem of asteroids.
That's not the asteroid belt, those are asteroids beyond the asteroid belt that are under the influence of Jupiter's gravity just enough to keep them in a stable configuration in the Lagrange points of Jupiter.
The main-belt asteroids have roughly circular to low eccentricity elliptical orbits.
This here is a coronal loop stretching from the suns photosphere into the suns corona. The kinetic energy released in a phenomenon known as magnetic reconnection, it is one of the current mysteries of modern physics as the standard model cannot properly account for the amount of kinetic energy released in the reconnection of magnetic fields.
That sentence was worded really bad. The basic idea is that the kinetic energy of charged particles in a magnetic loop undergoing magnetic reconnection have more kinetic energy than the standard model can currently account for accurately.
The green signifies that the asteroids are stably librating around the L5 and L5 Lagrange points.
this right here
is reason enough to get a 3d printer
These are some images of Iapetus taken by the Cassini space probe. One side of Iapetus is barren and rocky, the other is coated in frozen gases and liquids.
The reason for this is that Iapetus is tidally locked to Saturn (much like our moon to the Earth). One side ends up being lit a little closer to the sun than the other side does, so that side receives more intense sunlight. In this case the side receiving more intense light is the barren rocky side of Iapetus. Because this is the side that is on average close to the sun ices statistically sublimate more often on that side. When the ices sublimate they remain under influence of Iapetus's gravity and they will undergo deposition on the night side of the moon. (During this time the night side is the white icey side.)
The same is true for the icey side of Iapetus, gases will sublimate onto the night side of the moon when the icey side is lit (at this time the night side is the dark rocky side of the moon). But because this side is only lit on the far side of Saturn the sublimation happens at a slightly lower rate than it does on the dark rocky side. So the majority of sublimation happens on the rocky side.
Yeah, they do make calc 3 so much better.
Here are some vibration modes for resonances in a baseball bat.
These are some asteroids in the main asteroid belt as viewed from the Dawn spacecraft.
This asteroid here was viewed from the Japanese Hyabusa space probe, which returned the very first samples collected directly from an asteroid in orbit.
It's common that many people have trouble visualizing concepts in Calc 3.
If i remember correctly this gif should be comet ISON on the final stretch of its death-plummet.
Rotating reference frame of Acruithne, an asteroid caught up in Earths Lagrange points.
>implying that picture isn't science
The green glow in this image is created by the ionization of gases (primarily oxegen). It is called airglow.
If you go to the Wiki article on Fourier series or Fourier transforms you can click the gifs and go to their 'about' pages. There you can navigate to the account of the guy that makes them, he has a website that elaborates on how to make these animations. And he has more neat stuff on his site.
Here you go.
quantum is really interesting but the math will blow your hair back, I want to take numerical analysis and complex analysis but I dont think I am going to have the time. What did you cover in linear? I have heard its almost all eigenvalues/vectors
>numerical analysis and complex analysis
I'm taking those two next year, it looks really fucking interesting.
>What did you cover in linear?
Basic intro to vector spaces
Singular value decomposition
Convergence of infinite products and series with matrices
(More really cool stuff)
I suggest you watch the MIT Open Courseware Lectures on linear algebra.
the rig would try to stabilize the camera, making the handles move in the direction opposite of which it's trying to correct for
oh and you'd likely cry a lot too. those things are in the $10k+ range
The MIT Open Courseware lectures are probably what you need then.
Its really basic, you might not find everything you need but there may be a few things for you in there.
