liquid oxigen is magnetic
if the variable "z" is the radius and the variable "a" is the thickness (height) then the volume of a Pizza is "Pi*z*z*a"
think about it... math never has been that tasty before
First semiconductor used in mass-production semiconductor devices (transistors, diodes) was germanium.

liquid oxigen is magnetic
Because the word magnetic is rather vague, you have 3 type of magnetic effect:
diamagnetic
paramagnetic
ferromagnetic
(Some materials, such as mu-metal has the property of having a magnetic permeability)
Diamagnetic objects, ie, which magnetize in the opposite direction of the magnetic field in which they are placed. Levitation can be obtained when the magnetic force that applies to the diamagnetic object exactly compensates for the weight of the latter. It requires very high magnetic field gradients due to the low magnetic susceptibility of the diamagnetic materials. As a result, only a small number of materials can be avoided in large quantities in magnets commonly used in the laboratory. A number of research groups have recently used paramagnetic fluids to create additional buoyancy through the "magneto-Archimedes" effect. In this case, the object undergoes two additional forces: the classic Archimedes' thrust produced by any fluid and the magnetic thrust. For a gas at ambient temperature, for example oxygen, the conventional Archimedes thrust can generally be neglected because of the low density of the fluid. The "magneto-Archimedes" thrust supplied by a gas increases when the temperature of the latter decreases. Indeed, at constant pressure, the density of the gas is inversely proportional to the temperature. Similarly, the magnetic susceptibility of a paramagnetic material is proportional to its density and inversely proportional to the temperature. At atmospheric pressure, the magnetic susceptibility of the gaseous oxygen is therefore approximately inversely proportional to the square of the temperature, even in the vicinity of its boiling point.
In the absence of a magnetic field, the molecules do not all have permanent dipoles (ex: O2, N2 ...). On the other hand, a dipole forms in the presence of a field, it is an induced dipole that disappears with the field that gave it birth.
The liquid oxygen is a diamagnetic. ( if I'm not mistaken)
Common Sense isnt very common anymore.
lol, Dark, you're such a nerd.
Kike, a derogatory slur for Jews, originated from the Yiddish word of Kikel, means circle. And the term comes from back in the day when the Jews who immigrated through Ellis Island were illiterate were explained by the immigration officers to put an X on the paperwork. Since Jews associated an X with Christ (who Jews don't believe is the messiah) they wrote a circle instead. Eventually the Immigration officers started associating the Circles with the Jews who were coming in and called them "Kikels" and later "kike"
another theory suggests the word comes from the Jewish-Americans who used the words to put down Jewish Immigrants.

Since you reminded me.
A superconductor is an ideal diamagnetic.
the velocity of propagation of an electromagnetic field is the light speed. imagine that! how cool is that!!!
