Why Old Books Smell Good

“Lignin, the stuff that prevents all trees from adopting the weeping habit, is a polymer made up of units that are closely related to vanillin. When made into paper and stored for years, it breaks down and smells good. Which is how divine providence has arranged for secondhand bookstores to smell like good quality vanilla absolute, subliminally stoking a hunger for knowledge in all of us.

Ionization potential trends and explanations of the two noticeable anomalies.

For Boron to be ionized you are removing a high energy 2p electron, which is comparatively simple to removing the lower energy 2s electron in Beryllium.

Nitrogen’s ionization energy is simply the result of removing a 2p electron. However, when Oxygen loses its 2p electron, it loses a paired electron. Paired electrons are slightly less stable (i.e. higher energy), due to their mutual repulsion (this contributes to the ‘pairing energy’). Thus, this higher energy paired 2p electron is more easily removed, giving Oxygen a lower ionization energy than expected.

Nanotechnology Mirage Effect

UT Dallas scientists recently demonstrated that transparent carbon nanotube sheets, which can have the density of air and the specific strength of steel, can be used to make objects invisible. This invisibility for light oblique to the nanotube sheets is caused by the mirage effect, in which a thermally generated refractive index gradient bends light array from a hidden object.
