    Symmetry in Transportation Vehicle Design 

    Cars, trains, airplanes, boats, all of them are shaped symmetrically, looking at them from the front. This primarily helps with aerodynamics, keeping them stable when moving at high speeds and making sure the pressure the vehicle experiences is spread out evenly.

    Vectors in Electric Fields 

    An electric field is produced by a positively or negatively charged object or particle. It is the area around the said charged object or particle in which other charged objects and particles experience either an attractive force or a repulsive force, depending on the charges of the particles or objects (opposite charges attract, same charges repel). The electric field can be represented as a field of vectors with the charged object or particle in the center being the source of the field. The amount of force exerted on a particle by a certain particle decreases the further away they are from each other, in this way the magnitude of the vectors decrease as their distance from the reference particle.

    Salutations 

    What’s your name?
    I’m Joshua Castillo and pretty much everyone just calls me Joshua or Josh.

    What were your thoughts when you enrolled in this course?
    The first thing I thought was “OMG Sir Paul yay”, immediately followed by “OMG MATH NO”.

    How comfortable are you with math?
    I actually find math quite interesting, its just that it really never bodes well for my grades.

    What’s your dominant feeling right now?
