By Karl von Frisch

Seit mehr als 50 Jahren sind die Bienen in unserem Institut, wie in der Zeit der Ferien am Wolfgangsee, die Lieblingstiere meiner wissensGhaftlichen Arbeit. Ihr Farbensehen, ihr Riechen und Schmecken und die Beziehungen ihrer Sinnes leistungen zur Blumenwelt, ihre "Sprache" und ihr Orientierungsvermogen - das struggle das ratselvolle Wunderland, das zu immer weiterem Vordringen lockte. All mahlich haben sie uns aus der Schatzkammer ihres Daseins viele Neuigkeiten verraten. Diese hauften sich im Laufe der Jahre und verlangten immer dringender nach einer Besinnung und Dbersicht. Der Plan, dieses Buch zu schreiben, besteht daher schon lange. Aber groBe LUcken in unseren Kenntnissen waren so storend, wie die weiBen Flecken fUr den Betrachter der alten Erdkarten. Der Wunsch, ein moglichst geschlossenes Bild zu geben, rief immer wieder yom Schreibtisch zum scan, urn tieferen Einblick zu gewinnen - und jede neue Einsicht stellt neue Fragen. Ein Ende kommt nicht von selbst. guy muB es schlieBlich setzen. Ich warfare bemUht, aHgemein verstandlich zu schreiben und hoffe, daB auch noch in unserer Zeit, die immer mehr zur Spezialisierung drangt und immer weniger MuBestunden kennt, die Biene das Interesse weiterer Kreise fesseln kann. Sie hat es durch Jahrtausende vermocht. Mancher Unvollkommenheiten bin ich mir bewuBt. Nichts Besseres konnte ich mir wUnschen, als daB sie anderen als Anreiz dienen, die Arbeit fortzufUhren. Dem Springer-Verlag fUhle ich mich fUr sein Entgegenkommen und die gute Ausstattung des Buches in Dankbarkeit verbunden. MUnchen, im Marz 1965 okay. v.

Download E-books Biology: How Life Works PDF

By James Morris, Daniel Hartl, Andrew Knoll, Robert Lue, Andrew Berry, Andrew Biewener, Brian Farrell, N. Michele Holbrook, Naomi P

Rethinking biology capability rethinking the textual content, the visible software, and assessment.
Ordinarily, textbooks are constructed through first writing chapters, then making judgements approximately paintings and photographs, and at last, as soon as the booklet is whole, assembling a try out financial institution and ancillary media. This method dramatically limits the combination throughout assets, and decreases paintings, media, and exams to ancillary fabric, instead of crucial assets for scholar learning. 
Biology: How lifestyles Works is the 1st venture to strengthen 3 pillars—the textual content, the visible application, and the assessment—at a similar time. All 3 pillars have been built in parallel to ensure that every one suggestion is addressed within the ideal medium, and to make sure real integration. those 3 pillars are all tied to an analogous set of center innovations, proportion a typical language, and use an analogous visible palette. during this means, the textual content, visible application, and exams are imperative components of pupil studying, instead of simply add-ons to the text.

Biology: How lifestyles Works strikes clear of a spotlight on disparate issues, in the direction of an built-in process. Chemistry is gifted in context, constitution and serve as are lined jointly, the movement of data in a phone is brought the place it makes the main conceptual experience, and instances function a framework for connecting and assimilating information.
Biology: How lifestyles Works used to be predicted now not as a reference booklet for all of biology, yet a source all for foundational options, phrases, and experiments. this enables scholars to extra simply determine, comprehend, and practice severe strategies, and boost a framework on which to construct their figuring out of biology.
Biology: How existence Works used to be written with six issues in brain. brought in bankruptcy 1 and revisited all through, those subject matters supply a framework that is helping scholars see biology as a collection of attached ideas. particularly, the topic of evolution is emphasised for its skill to provide an explanation for and expect such a lot of styles in biology.
Across Biology: How lifestyles Works—whether scholars are taking a look at a determine within the e-book, gazing an animation, or interacting with a simulation—they continually see a constant use of colour, shapes, and design.
Every image—still and in motion—engages scholars via being vivid, transparent, and approachable. the result's a visible surroundings that's expertly designed to drag scholars in, deepens their curiosity, and is helping them see an international of organic processes.
A visible Framework
To aid scholars imagine like biologists, the visible software is designed to be a framework for college students to hold the strategies and fasten principles. person figures current foundational options; visible Synthesis figures tie a number of suggestions throughout chapters jointly; animations carry those figures to lifestyles; and simulations enable scholars have interaction with the techniques. jointly, this visible framework permits scholars to maneuver seamlessly backward and forward among the large photograph and the details.
Developed via a extensive group of prime technology educators, the exams for Biology: How existence Works deal with every kind of studying, from bear in mind to synthesis. they're designed for use in numerous settings and are available in a variety of codecs (multiple selection, true/false, loose response).
Assessment is seamlessly built-in into the textual content and the visible software (both in print and interactive). every time an teacher asks a scholar to have interaction with Biology: How lifestyles Works—whether it's examining a bankruptcy, staring at an animation, or operating via an experiment—the chance to evaluate that have exists.
Many of the questions and actions for Biology: How lifestyles Works are prepared in units referred to as Progressions.  Questions in a development are aligned with a number of middle innovations, and are designed to maneuver a scholar from easy wisdom to raised order talents and deeper understanding.  Progressions questions can be utilized separately or in a chain as pre-class quizzes, in-class clicker questions or actions, post-class homework, or exams.  whilst utilized in series, Progressions offer a hooked up studying direction for students.

In fixing those, interdisciplinary co operation will end up useful or even crucial, if improper and slim decisions are to be shunned. Co-operation among scientists and institutes engaged in numerous branches of study will make attainable a greater und er status of the advanced useful courting which ensure monetary occasions and their mutations open air Western business society than will be commonly accomplished through an remoted strategy. clever total financial making plans, for instance, calls for technological research simply up to an actual wisdom of social constitution or actual context. At this element the economist needs to co-operate heavily with the engineer if he needs to prevent wasting his approach as a rule styles of development.
