Justn's white???
That's right my dude, 3 were killed, Trae and someone else were hit. The news didn't even say it was Trae. I found out through WSH.

ICP Worst band ever.
Yeah because I don't go to Walmart

I feel bad for you, you actually had to look that up.

I'm beginning to think you like ICP.

Magnets, how do they work? You can't explain that scientist.

Catholic Parent's Preschooler answer: God's magical miracle
First Year High School Chemistry Student answer: You know how atoms have electrons? Do you remember how each of those electrons both orbits around the nucleus (think of the Earth rotating about the Sun every 365.25 days or so) and the electrons also have an intrinsic spin (think Earth rotating every 24 hours to make a complete day)? Well, in a magnetic material, the atom's electrons tend to line up their path with each other so they all spin in the same direction. What you also need to know is that any charged particle that moves will also create a magnetic field. If all of the electrons in a material are able to line up with each other, than their combined effect increases and so does the magnetic field that is created. These are how magnets operate.
First Year Physics Student in College: Some elements have more unpaired electrons than others. Remember the "spin-up" and "spin-down" when filling out your atomic orbitals for some of your elements? Well, before you put two electrons into the same orbit, first you make sure each orbit is filled. Some elements are better suited to make magnets than others because their shells are only partially filled. Where are the large shells partially filled? Well, that would be towards the middle of the transition metals, where the 3d is starting to get half full (we'll neglect electron promotion for now).
Now that we know certain pure materials have an appropriate electronic structure to induce a magnetic moment, we need to understand how magnetic domains operate. If you were to take a group of atoms all pointed in the same direction, their magnetic moments will be additive and point in the same direction. For the strongest magnets, all of the domains will be able to point in roughly the same direction. This is called anisotropy, and permanent magnets maintain this. Having a large anisotropy will give the magnet a large coercivity value, which means the magnet will hold it's properties in harsh conditions until an extreme demagnetizing field (or high temperature) is reached. These domains are generally smaller in size than a structural grain, and are never larger than a grain itself. Grain size in magnetic materials is very important to magnetic strength.
Baby Steps Outside of First Year Physics, and Where We Currently Stand: Why do we have rare earth elements such as neodymium in our current, strongest magnets? Well, the rare earth component provides most of the magnetocrystalline anisotropy intrinsically responsible for the coercivity in a magnet, while the magnetization itself arises from the transition metal sublattice (i.e. Iron). For compounds in which the 4f shell has a nonzero orbital magnetic moment, theoretical analyses demonstrated that the behavior of the R (rare earth) ion under the influence of the exchange and crystalline electric field controls the easy magnetization direction and accounts for the majority of the uniaxial anisotropy.
The light rare earth compounds that contain the R2Fe17 phase (same as the rhomohedral Th2Zn17 structure) unfortunately have a low Curie temperature, which is why our Nd-Fe-B magnets stink under hot conditions and the samarium cobalt still reigns supreme. Current studies are being conducted to increase the coercivity and anisotropy of our neodymium magnets.

hahaha
Majofo, you have to have a taste for it, trust me, when I first started I had no idea what they were saying, you listen to more and more and get an ear for it and concentrate on it. You get into it. Gets intense man.
Charles, for the most part, good lineup
