Seafloor surveying with acoustic remote sensing has become a powerful tool for researchers and professionals seeking knowledge about the structure and behavior of the seafloor. In particular, sidescan sonar is proving to be the preeminent technique, but its data is often difficult to interpret due to the physics of acoustic remote sensing, and to the varied geological processes at play. This handbook not only presents all the fundamentals but also explains how to interpret sidescan sonar imagery and bathymetry. It fully explores the most recent advances, both in the technology and in the knowledge of marine structures, and provides deep insights for interpretation and decision-making. Broadly expanded and updated from the previous 1997 “Handbook of Seafloor Sonar Imagery”, this handbook is indispensable to oceanographers, resource exploiters, telecommunications engineers, and marine researchers of all kinds.

Tumstock Om jag inte har så bråttom kan det hända att jag går och handlar på ICA Björksätra. Folk vill prata. Här kan jag möta hela världen på en förmiddag. Den samlade kunskapen, och viljan att förmedla den, är påtaglig. En dag stoppar en gammal man mig. ”Hör du, Andersson.” (Han har läst mina verktygsbetraktelser i tidningen.) ”Jo, jag har en egendomlig tumstock hemma i en låda. Den skulle du ha tittat på, du som skriver om verktyg.” Mera blir det inte sagt. Ett par veckor senare träffas vi igen ”Hör du, Andersson…” Efter ännu ett par veckor ringer det på min dörr och utanför står den gamle mannen med sin tumstock i näven. Och nog är den lite egendomlig. Den är en aln lång, alltså måttet från armbågen till spetsen av långfingret. Den är tillverkad i buxbom, ledad i fyra delar och lederna är av mässing. Trots att den är knappt 60 centimeter lång, så kan man utöver detta mäta flera sorters tum: engelska inch, verktum och decimaltum som är en slags transformering av den gamla foten. ”Den här ska du ha!” säger han och berättar samtidigt hur han växte upp granne med poeten Stig Sjödin på bruket i Sandviken. De kroppsnära måtten är på väg att försvinna. En tum är inte alltid en tumme. En inch är 25, 4 mm, en wienertum 26,3, en burgostum 23,2, en preussisk decimaltum hela 37,7 och en dansk tum 26,2. Och så vidare. Måttet växlar mellan länder. Förr i tiden klagade engelsmännen på att de fick för lite av det virke de köpte från Danmark. Danskarna bedyrade att de levererat korrekta mängder, på tummen när. Men det visade sig att virket hade torkat och krympt under transporten. Därför mättes virket i fortsättningen i en större tum än den engelska för att ge lite krympmån. Så det var lite si och så med tummen på den tiden. Den gamle mannen som besökte mig heter Helge Astnell, om han nu fortfarande lever. När han kommer cyklande är han snart 92 år, men verkar åtminstone tjugo år yngre. Det är imponerande. Kan jag själv hålla balansen på en cykel vid 92 år ålder? Troligtvis inte. Helges tumstock är av den allra äldsta sorten. Visserligen har det funnits tumstockar allt sedan antiken, men den ledbara tumstocken räknas från året 1883. Då uppfann nämligen svensken och chalmersingenjören Karl-Hilmer Johansson Kollén just dessa stockar med tre leder av mässing. Som byggnadssnickare har jag väl brutit av några av den moderna sorten. Det var ju något av en sport att så fort som möjligt vika ut tumstockarna inför någon mätuppgift, en gjutform, gipsskiva eller regelvägg. Det blev som en ritual och vi yngre härmade de äldre och mera erfarna snickarna. Och lite svinn får man ju räkna med om man ska bli mäster. Idag påminns jag om min egen ålder när jag besöker byggvaruhuset och vill ha en 2”x4” regel och den medelålders mannen i brädgården är tvungen att fråga en kollega om hur mycket det blir omräknat i millimeter. Jag påminns också om min ålder en dag när jag sitter vid min dator och skriver en av dessa verktygsbetraktelse, när jag oväntat förlorar all kraft och känsel i min vänstra sida. Vänster arm och ben lyder mig inte. Jag har drabbats av en stroke. Det är min 64:e födelsedag, livet stannar upp, mina cirklar rubbas. Men jag hade en enastående tur. Skottet missade. Rehabiliteringen gick smidigt och skottet verkar inte ha lämnat efter sig några skador eller ärr. Men man står där i skogsbrynet och darrar som en råbock just vid skottögonblicket. Man ser den okände jägaren lägga geväret tillrätta på axeln. Hur han siktar noga och trycker av. Och jag kan ännu höra hur skottet ekar genom skogen. Plötsligt blir allting så tydligt. Livet har sina begränsningar. Det som ska göras måste göras nu. Den gången framför datorn och verktygsbetraktelsen var jag bara ett par centimeter från en ny tillvaro i de sällare jaktmarkerna. Eller rättare sagt: en tum. Sedan kan det faktiskt kvitta om det var frågan om en verktum, en engelsk inch eller en preussisk decimaltum.

På himlen kan man se en mängd olika optiska fenomen. Vissa så vanliga att vi inte tänker på dem, än mindre funderar på hur de uppkommer eller vad de innebär: Varför är himlen blå? Kan man se regnbågar på vintern? Hur uppkommer vattenspeglingarna över heta asfaltytor? Vilken väderutveckling kan olika moln förebåda?Andra fenomen är sällsynta eller mer spektakulära, och de måste en gång i tiden ha varit mer än skrämmande: Solförmörkelse, storslagna halofenomen med ringar och bågar på himlen, magnifika åskväder, norrsken. Ytterligare några lägger man kanske inte märke till om man inte vet var (eller när) man skall titta: en Venuspassage framför solskivan, den gröna blixten från den nedgående solen eller bisolens regnbågsfärgade ljusfläck. Dessa och många andra optiska fenomen i atmosfären förklaras i denna bok. Inledningsvis ges en kort beskrivning av fysiken bakom olika fenomen. Därefter behandlas systematiskt himlens olika färger, moln, haloer, regnbågar, andra effekter av vattendroppar och partiklar, hägringar och slutligen vad vi mot natthimlen kan se i rymden. Boken förklarar de olika fenomen på ett enkelt sätt och riktar sig till dem som fascineras av och vill veta mer om olika optiska fenomen i naturen, utan att för den skull nödvändigtvis ha en naturvetenskaplig bakgrund. Den är rikt illustrerad med fotografier och förklarande figurer. Boken kan användas som kurslitteratur vid universitet och högskolor, eller som fördjupningslitteratur vid gymnasiet. Författaren Göran Loman är doktor i naturgeografi och har författat flera populärvetenskapliga böcker och kursböcker i meteorologi och klimatologi.

Den här boken tar dig till ett universum som utgår från en hypotes om att en elektrisk instabilitet råder i ett absolut vakuum där positron-elektron parbildning sker spontant. Med nya ögon beskrivs hur materia och antimateria byggs upp och hur gravitationens gåta får en förklaring. Gammastrålning från positron-elektron annihilation förklaras med en ny modell och frågor om mörk energi, mörk materia och svarta hål, som fysiker inte riktigt har en bra förklaring till, får du stifta lite mer bekantskap med i boken. Ljusets utbredning i rymden och planeters omloppsbanor kommer också att belysas med den nya hypotesen som utgångspunkt. Boken ger dig nya tankar om vårt storslagna universum.

A Nobel Prize-winning physicist explains what happened at the very beginning of the universe, and how we know, in this popular science classic.Our universe has been growing for nearly 14 billion years. But almost everything about it, from the elements that forged stars, planets, and lifeforms, to the fundamental forces of physics, can be traced back to what happened in just the first three minutes of its life.In this book, Nobel Laureate Steven Weinberg describes in wonderful detail what happened in these first three minutes. It is an exhilarating journey that begins with the Planck Epoch - the earliest period of time in the history of the universe - and goes through Einstein's Theory of Relativity, the Hubble Red Shift, and the detection of the Cosmic Microwave Background. These incredible discoveries all form the foundation for what we now understand as the "standard model" of the origin of the universe. The First Three Minutes examines not only what this model looks like, but also tells the exciting story of the bold thinkers who put it together.Clearly and accessibly written, The First Three Minutes is a modern-day classic, an unsurpassed explanation of where it is we really come from.

Intended for a one- or two-semester course, this text applies basic, one-variable calculus to analyze the motion both of planets in their orbits as well as interplanetary spacecraft in their trajectories.  The remarkable spacecraft missions to the inner and outermost reaches of our solar system have been one of the greatest success stories of modern human history. Much of the underlying mathematical story is presented alongside the astonishing images and extensive data that NASA’s Voyager, NEAR-Shoemaker, Cassini, and Juno missions have sent back to us. First and second year college students in mathematics, engineering, or science, and those seeking an enriching independent study, will experience the mathematical language and methods of single variable calculus within their application to relevant conceptual and strategic aspects of the navigation of a spacecraft. The reader is expected to have taken one or two semesters of the basic calculus of derivatives, integrals, and the role that limits play. Additional prerequisites include knowledge of coordinate plane geometry, basic trigonometry, functions and graphs, including trig, inverse, exponential, and log functions.The discussions begin with the rich history of humanity’s efforts to understand the universe from the Greeks, to Newton and the Scientific Revolution, to Hubble and galaxies, to NASA and the space missions.   The calculus of polar functions that plays a central mathematical role is presented in a self-contained way in complete detail. Each of the six chapters is followed by an extensive problem set that deals with and also expands on the concerns of the chapter. The instructor has the flexibility to engage them with greater or lesser intensity.“I have been an aerospace engineer for 39 years and honestly, it would be hard for me to overstate how valuable I believe this book will be to numerous scientific and engineering disciplines and in particular to the future of aerospace engineering … This book is perfectly crafted to motivate, educate, and prepare the scientists and engineers who wish to reach for the sky and beyond.”   —Dr. Mario Zoccoli, Aerospace Engineer, NASA and Lockheed Martin

This compact yet informative Guide presents an accessible route through Special Relativity, taking a modern axiomatic and geometrical approach. It begins by explaining key concepts and introducing Einstein's postulates. The consequences of the postulates - length contraction and time dilation - are unravelled qualitatively and then quantitatively. These strands are then tied together using the mathematical framework of the Lorentz transformation, before applying these ideas to kinematics and dynamics. This volume demonstrates the essential simplicity of the core ideas of Special Relativity, while acknowledging the challenges of developing new intuitions and dealing with the apparent paradoxes that arise. A valuable supplementary resource for intermediate undergraduates, as well as independent learners with some technical background, the Guide includes numerous exercises with hints and notes provided online. It lays the foundations for further study in General Relativity, which is introduced briefly in an appendix.
