    Organic vs. Inorganic Chemistry: Pros & Cons

    At present I am still uncertain about my academic education (that is, which subject to study). If I were to decide on chemistry, would you commend organic or inorganic chemistry? Why? How are the two different when it comes to studying them? Answers are appreciated.

    Can sunlight be turned into other things besides energy.

    Actually, I think plant only use the sunlight as an energy source to produce glucose and oxygen from water vapor and carbon dioxide. CO_2(g)+H_2O(g)+energy\rightarrow C_6H_{12}O_6(s)+O_2(g) It is true that energy and mass (matter) has a distict relationship \left(E=mc^2\right), but the...

    Circle Deflection: Calc Outbound Angle After Collision

    Isn't this just the reflection law, \theta_{inbound}=\theta_{outbound} with theta measured on the tangent (plane) of the collision surface at the collision point?

    Calculating Displacement with Air Drag: A Differential Equation Approach

    I solved the integral to \int \frac{dv}{A-Bv-Cv^2}=-\frac{2\tan^{-1}\left(\frac{B+2Cv}{\sqrt{-B^2-4AC}}\right)}{\sqrt{-B^2-4AC}}, so then t=-\frac{2\tan^{-1}\left(\frac{B+2Cv}{\sqrt{-B^2-4AC}}\right)}{\sqrt{-B^2-4AC}} Working with this, I get that...

    Calculating Displacement with Air Drag: A Differential Equation Approach

    This is not a homework problem, just an idea I had. If we have a sphere which is being accelerated in space by a force \vec{F} and we take the drag into account, what would the displacement be after t seconds? If the drag force is \vec{D}=-c_1v-c_2v^2, then the acceleration would be...
