12.8 Petabytes, You Say?

MadUndergrad writes "Dr. Jonathan Spanier from Drexel University has come up with a novel way to greatly increase data storage density: water. Specifically, they propose using hydroxyl ions to stabilize minute ferroelectric wires. These wires could be many times smaller than what is possible today, enabling data densities in the neighborhood of 12-13 PB per cubic centimeter. While there are still many problems to be resolved before drives using these can be manufactured this technology does seem promising. For one thing, it would be non-volatile, but could apparently be made to act as RAM. The fact that this is coming out of a university gives me hope that this technology won't turn out to be just so much vapor."

Bad physics

[Anonymous Coward]

Without commenting on the competence of the researcher, whoever wrote the press release doesn't have the first idea what they're talking about.

"Ferroelectric materials possess spontaneous and reversible electric dipole moments. These dipole moments are times when the material gains a charge, in this case an electric one. For example, the Earth's magnetic field generates a dipole moment that causes compasses to face north"

First sentence is correct. Second sentence is baloney. A dipole moment is not anything to do with time, and an electric dipole moment does not mean a material gains a net charge, although it might correspond to a charge developing on a certain surface. Third sentence: the dipole moments associated with the earth's magnetization are nothing to do with the dipole moments in a ferroelectric material. The former are the result of intrinsic magnetic moments in atoms, the latter the result of differing charge distributions in materials. Similar names, completely different things.

Mod parent up +5 It does make sense!!!!!

Here is the exact text:

A physics professor and his assistant are working on liberating negatively charged hydroxyl ions, when all of a sudden, the assistant says, "Wait, Professor! What if the salicylic acids do not accept the hydroxyl ions?" And the professor responds, "That's no hydroxyl ion! That's my wife!"
-Joke from Dexter's Laboratory

I've always wanted to understand this joke, from many years ago. @___@;;;
I was reminded of this joke today when we talked about hydroxyls in biology and chemistry. :XD:

To liberate is to set free. The point of this joke is that it's saying that a negatively charged hydroxyl ion is equivalent to a professor's wife. Hydroxyls, which contain at least one hydroxide (-OH), are alcohols. Does the joke mean the wife is drunk?
I then researched salicyclic acids and I found out that salicyclic acid is a plant hormone used as a medicine for acne. More importantly, it is a carboxylic acid. We learned in biology today that an ester linkage is formed between a carboxyl and a hydroxyl, and in this case, salicylic acid and hydroxyl ions create aspirin, the pain reliever.
Now isn't that cool? :D
Lastly, the hydroxyl ion is NEGATIVELY charged, so the wife has had an excess of alcohol.
Basically, therefore, the professor was only trying to give some aspirin to his wife, who has a hangover.
ROTFLMAO.

Btw... I find it creepy that googling this returned six results.
