Yes, of course the subject is meant seriously.
The satire is of the pop-sci click-bait quality of the article title in the OP.
Compare it to the much more professional scientific dialog seen in this link to a Research Gate thread where the question is asked "What is negative capacitance?".
Note in particular the banter between Vasili Ivanovich Dimitrov and Petr Viscor, and Maxim Ershov. Comments from each respectively, like,
"Both by definition (The capacitance, C is the ability of a body to store an electric charge) and formalization (The capacitance, C, is defined as the ratio of the magnitude of the charge on either conductor to the potential difference between the conductors) capacitance conceptually can’t be negative conception. So, actually this (negative capacitance) is nothing but slang that is used by non-educated authors." - V. Dimitrov
From there the discussion gets more lively and deepens into illustrating different thoughts regarding static vs dynamic electronic situations, etc etc etc., but IMO boils down to the misapplication of oversimplified jargon (negative capacitance) to a complex phenomena(s) that could be seen in several different possible scenarios.
Another theory is that this is a result of, "the lower spatial symmetry corresponding to lower monophasic capacitance."
But the 23rd Street Spindizzy tended to have problems. Mayor John Amalfi never could get it fixed right.
Negative capacitance - equivalent to negative temperature, ie, minus degrees Kelvin, which those in the Upper Midwest are close to experiencing this week.
Which in turn imparts negative viscosity to outdoor liquids, ie "fried ice" ... "To cover the issue, I believe that it’s proper time and place to remember grand René Descartes (Renatus Cartesius). I cite “…Define the sense of the words, and you will clean up the World from the half of the possible delusions …” - V. Dimitrov
I'm not griping or anything, but shouldn't you guys have saved this for April 1?
Sure, save real news that sounds bogus for April 1. That way when people _don't_ believe it the joke will be on them.
My nephew was born on April 1. Everyone thought it was a joke until the pictures went around, and still a few didn't believe it.
Oh, I know it's real Jon .... but the way the article is written - and their definition of "negative capacitance" is vague to the degree usually reserved for April Fools' day ... no harm intended. Now, school me on the implications "negative capacitance" has on the real world .... and let me know how many PhDs have been awarded based on this research. Expiring minds wanna know.
Ya' know, I was just thinking about this while shaving this morning.
