Sometime back in May:

• Quantum Physics II
• Stellar Astrophysics
• Visual Art I

Sometime in the middle of June:

• Quantum Physics II
• Stellar Astrophysics
• Electronics II + Lab
• Visual Art I

Sometime in the beginning of July:

• Quantum Physics II
• Stellar Astrophysics
• Electronics II + Lab
• …

I would kill for this schedule!  Except I wouldn’t have Visual Art in there…just my opinion… :D

If had nine lives, I would sure waste one studying this.

Research scientists at Columbia University’s Fu Foundation School of Engineering and Applied Science have achieved a breakthrough by proving that the carbon material graphene is the strongest material ever measured.

Graphene holds great promise for the development of nano-scale devices and equipment. It consists of a single layer of graphite atoms arranged in a hexagonal lattice, similar to a honeycomb. As a two-dimensional material, every atom is exposed to the surface. It forms the basis of graphite fibers used in tennis racquets and other durable products. When rolled, very useful tiny tubes called nanotubes can be fabricated.

This is an awesome site to help everyone out there like me.  Whether you like to just randomly learn more and more about mathematics, like me, or need to struggle through high school geometry, this site helps!

It has an easy-to-navigate interface that will let you quickly find the topic or theory you need and research it more in depth. 

Hope it helps!!!

The del operator, denoted with what is called the nabla symbol (an inverted delta), is a differential operator connecting differential calculus of functions to the study of vectors, and vector-valued functions. The del operator has several forms, and is defined by

where ∂/∂x indicates the partial derivative with respect to x (similarly for y and z), and i, j, and k indicate the three standard unit vectors (all in the Cartesian coordinate system).

To a scalar function, F(x,y,z), in the Cartesian coordinate system, the del operator may be applied to create what is known as the gradient of F — defined as

The inclusion of the unit vectors in ∇ lead to the gradient’s being a vector-valued function in three dimensions, and the vector consequently is directed toward the greatest increase in F, at any point (x,y,z). Its magnitude is equal to the maximum rate of increase, and hence may be used as an analog to the 1-dimensional derivative, in 3 dimensions.

When ∇ is applied to a scalar field (function) of the form F(x,y,z), and a vector field a (= <a_1, a_2, a_3>) is chosen, the directional derivative takes the form

in which the dot-product of the gradient of F and and the vector a is taken. The most common analogy is this: if ∂F/∂x gives the rate of change of F in the x direction, then ∇F • a gives the rate of change of F, in vector form, toward the vector a. a is taken to be the unit vector for this calculation. This operation allows the rate of change of a scalar field with respect to an arbitrary — and sometimes changing — direction of a vector (a need not be a vector composed only of constant components), to be calculated. Its most common application for this operation lies in the field of fluid dynamics.

Coming soon: ∇applied to vector functions!

Multivariable calculus <3

Was just teaching the very beginning steps of this to mi novia a couple days ago :D

This is what you get to look forward to!

remember folding@home? SETI@home? distributed.net? (I had a few dozen machines working on a 3des contest there at one point long ago.) If you liked that stuff, chances are you’d also like having your computers’ idle cycles put to work searching through LHC data to support physics experiments like the CMS and ATLAS, and maybe even contributing to the search for the Higgs Boson.

Just think, if only people were off Tumblr long enough for their computers to have idle cycles…

The possibilites…

Antiproton ring found around Earth

Satellites had already discovered positrons - the antimatter partners of electrons - in the radiation belts. Now a spacecraft has detected antiprotons, which are nearly 2000 times as massive.
