Happy birthday, James Clerk Maxwell! 🎂 🎓 ⚡
Let's remember him not only for essentially formulating the full theory of electromagnetism, but also for founding kinetic theory and statistical mechanics (with Boltzmann and Gibbs), for his contributions to thermodynamics, the mechanics of continua, the theory of colours (I heard he took the world's first colour photograph); for his views about probability theory; and for MANY other things.
Among my favourite quotes:
> "They say that Understanding ought to work by the rules of right reason. These rules are, or ought to be, contained in Logic; but the actual science of Logic is conversant at present only with things either certain, impossible, or *entirely* doubtful, none of which (fortunately) we have to reason on. Therefore the true Logic for this world is the Calculus of Probabilities, which takes account of the magnitude of the probability (which is, or which ought to be in a reasonable man's mind)." – Letter to L. Campbell, 1850 <https://archive.org/details/lifeofjamesclerk00campuoft>.
> "In the popular treatise, whatever shreds of the science are allowed to appear, are exhibited in an exceedingly diffuse and attenuated form, apparently with the hope that the mental faculties of the reader, though they would reject any stronger food, may insensibly become saturated with scientific phraseology, provided it is diluted with a sufficient quantity of more familiar language. In this way, by simple reading, the student may become possessed of the phrases of the science without having been put to the trouble of thinking a single thought about it. The loss implied in such an acquisition can be estimated only by those who have been compelled to unlearn a science that they might at length begin to learn it." – In "Tait's 'Thermodynamics'", 1878 <https://doi.org/10.1038/017257a0>.
> "it is our part to provide for the diffusion and cultivation, not only of true scientific principles, but of a spirit of sound criticism, founded on an examination of the evidences on which statements apparently scientific depend." – Introductory Lecture on Experimental Physics, 1871 <https://archive.org/details/scientificpapers02maxwuoft>.

People who study #magnetics, #Electromagnetics, and/or #bioelectromagnetics, is a microgauss and a milligauss the same thing? Would it be possible to create a disk of 0.5 inches in diameter and 0.25 inches thick with a magnetic field strength of 37.4 microgauss? In researching my measurements, this seems like a really weak magnet, but I also know that the smaller units (not sure if it's micro or milligauss) is used somehow in regards to body tissues... There's a link here I'm trying to figure out, and I don't have enough info yet.

I apologize in advance, but it #BogglesTheMind that the speed of light equals the inverse of the square root of the product of the permittivity and the permeability of vacuum. #TeamMaxwell #Electromagnetics #MaxwellsEquations

Me 'n Maxwell's Equations, painted for me by my sweet 6yo nephew (with help from my art-saavy sister & equation-saavy brother-in-law). I'd love to write an accessible book on these equations, once #SubatomicWriting is published!

Hi folks, I really enjoy Mastodon. It does remind me of the olden days of #irc and the #BBS era (in a good way).
I teach computer engineering technology at the University of Kentucky. I'm originally from #Germany.
My main interests here:

#softwareEngineering
#git
#linux
#unix

I'm a #volcanologist from the Philippines working mostly with #Taal and #Mayon volcanoes. I work mostly on #electromagnetics applications and methods, but also used to work with #seismic methods (#tomography). Nowadays though #DRRM (disaster risk reduction and management) occupies most of my time. I also do seismic hazards from time to time but volcanic eruptions are more exciting and spectacular.
Picture below was back 2014 when I was finishing up my PhD, inside Taal Volcano Main Crater. -
