Matthew Morgan

This book explores the fundamental but often overlooked connection between Maxwell's equations, as they are taught in undergraduate electrical engineering courses, and special relativity. Written for an audience of practical engineers instead of theoretical physicists, it exposes the underlying contradictions brought about by the emergence of electromagnetic theory, one of the greatest triumphs in mathematical physics of all time that unified the phenomena of electricity, magnetism, and light, into a world in which the classical Galilean principle of relativity was considered incontrovertible. It explains how Einstein redefined the concepts of space and time and what it means to measure them, while altogether disbanding the notion of global simultaneity. A manifestly relativistic formulation of electromagnetic laws is first presented and then applied to common engineering problems, like the interaction of electromagnetic fields at dynamic interfaces, the derivation of propagating modes in closed metal waveguides, and the foundations of microwave network theory. Mathematical toolkits for relativistic analysis, such as tensor notation and spacetime algebra, are explained. These tools are then used to analyze the consequences of motion at relativistic speeds upon otherwise well-known electromagnetic circuit behaviors. Well-drawn and insightful diagrams along with articulate explanations help the reader to gain an intuitive understanding of four-dimensional spacetime and the nature of the electromagnetic field in that context, while summary tables and comprehensive appendices serve as a resource for further selfdirected exploration. Readers trained in microwave engineering will learn to see their field from a new perspective, and shall gain from that new insight the ability to conceive of unexpected solutions to practical engineering problems that might otherwise defy one's intuition.

Kõik sai alguse kaeraküpsisest. Samal ajal kui intensiivraviarst Matt Morgan päästis väikest patsienti, kes oli küpsisetüki kopsu tõmmanud, märkas ta akna taga lendavat linnuparve. Kuidas jäävad ellu linnud, kes lennates võõrkeha sisse hingavad? Sellest hetkest sündis doktori peas mõte kirjutada raamat kõigist neist imelistest meetoditest ja leiutistest, mida inimmeditsiin on loomariigist kopeerinud. Känguru aitas tõhustada katseklaasiviljastamist. Kaelkirjak tõi kergendust astmaatikuile. Kärekülmas Arktikas elavad linnud andsid uue meetodi alajahtunud inimeste soojendamiseks. Küürvaal kinkis elupikenduse haige südamega patsientidele. Mõistmine, kuidas inimene on elanud ja elab kõrvuti miljonite teiste loomaliikidega, võib viia uskumatute avastusteni meditsiinis ja päästa tuhandeid inimelusid. Matt Morgan on Walesi arst, teadlane ja ajakirja British Medical Journal kaasautor. Lisaks teeb ta kaastööd paljudele ajalehtedele, raadiojaamadele ja telekanalitele ning Briti Kuninglik Ühing nimetas ta 2020. aastal David Attenborough' nimelise teaduse populariseerimise auhinna nominendiks. "Üks meditsiin" on tema teine raamat." Igas raamatus peab olema midagi, mis paneb mõtlema, elu ja teadmisi uues valguses vaatama. Kui arvad, et tänapäevane meditsiin on näide inimkonna supervõimest, siis eksid - sageli oleme kopeerinud evolutsioonis miljonite aastate jooksul välja kujunenut, me lihtsalt ei teadnud, et loomariigis on mõned meie meditsiiniimed igapäevased ega vääri suuremat tähelepanu. No ja mina ei teadnud, et kunstliku viljastamise õnnestumise üle on lätlastel põhjust uhke olla (ja pikka viha ei pea)." Marko Mägi, zooloog"Meil on looduselt veel nii palju õppida! Kõik vastused on meid ümbritsevas kirjas, tuleb olla piisavalt tark, et need üles leida. Neid lugusid lugedes avanevad hämmastavad õppetunnid ja seosed. Meie, inimesed, oleme osa loodusest, see leidis veel kord kinnitust. Inspireeriv raamat." Kärt Tomberg, Põhja-Eesti regionaalhaigla patoloog

Mika oli kovin huolissaan. Hän pelkäsi hämähäkkejä ja avaruusolioiden hyökäystä, ja joskus hän oli huolissaan siitä, etteivät muut pitäisi hänestä. Mutta onneksi Mikalla on Luppa-koira, joka näyttää että parast tapa vapautua huolista on jakaa ne ystävän kanssa. Herkästi kerrottu ja huumorilla höystetty rohkaiseva tarina puhumisen tärkeydestä!
