ode to carbon dioxide and nitric oxide




some people want to build cars that don't burn gasoline. they say there is too much carbon dioxide emitted in the exhaust. they also say they want to save the ozone. we are all friends on this blog site, so let me be totally honest with you. carbon dioxide does not deplete ozone...
but let's first start at the beginning. do you even know what ozone is? ozone is a triatomic oxygen molecule (O3). it is formed in the atmosphere when uv light from the sun reacts with diatomic (O2) oxygen molecules (what we need to breathe in order to survive). a photon of wavelength less than 240 nanometers (nm) will strike the bond between the two oxygen atoms in O2 forming two free radical oxygen atoms. these will then react with other O2 molecules forming two O3 molecules, ozone. when ozone is struck with photons of wavelength 200-310nm the molecule will break apart, forming an O2 molecule and a free radical oxygen atom which could potentially react with another free radical oxygen atom resulting in another O2 molecule. we could metaphorically explain this as a battle between ozone and O2.
there's a chemical compound called nitric oxide (nitric oxide is a highly celebrated compound receiving recognition as molecule of the year in 1992). nitric oxide is emitted in the exhaust from gasoline-burning engines. it acts as a catalyst in the conversion of ozone back to O2. thus, the more nitric oxide present in the atmosphere, the less ozone and more O2 is present.
[i would add parenthetically that plants do not 'breathe' oxygen (O2), they 'breathe' carbon dioxide (in fact, they 'exhale' oxygen(O2)). they will not survive without carbon dioxide.]
well if i have learned anything from chemistry it's that ozone is a non-living, non-feeling chemical compound and i must add that it is poisonous to humans. ozone robs our atmosphere of our precious oxygen (O2). then we have these people wanting to limit carbon dioxide and nitric oxide emissions, and inadvertently, i am sure, stifling our poor plants, which are beautiful to see, and another source of our precious oxygen. limiting nitric oxide emissions will slow down the conversion of deadly ozone to lovely O2.
so let's sum this all up: people want to decrease O2 which we need to live and increase O3 which is poisonous...
we must act, and we must act now!! instead of these hybrid, electric, or hydrogen cars, i make a new proposal. save the trees, and buy one of these:

ode to geeks

i am a chemical engineering student. i know, i know; the stereotype is that i am a complete geek, nerd, socially awkward weirdo. i mean, come one, who gets excited about hydrogen bonding? who gets excited about the high heating value of water, ∆H of formation of propane, or mechanical and internal energy balances? who sees an integral or a partial differential equation with love and anticipation? i admit, i am quite the nerd. but really i am cool. really, most engineers are cool. talk to us; you will see. unfortunately, as i will explain, this is not the case for all engineers and tech gurus.
i was on the internet the other day searching for a father's day gift for my father. he, too, is an engineer. i thought he might like special cases to carry his blueprints. i came across these pictures. these pictures define geekiness. these pictures are the reason engineers get a bad reputation. do not judge us all because of a few; i beg you!!


yeah!! stylin' case.
