Φυσική, τόμ. 2
David Halliday, 2002
A physics text that opens with a car, a black hole and the boredom of October, and treats its students' lives as part of the subject. A plain-spoken physics text with a curious, wondering voice, moving from everyday objects to large ideas at an unhurried textbook pace.
Feels like curiosity, awe and wonder. About nature, time and memory.
Who it’s for
You may like it if you enjoy physics explained through ordinary examples and are willing to follow worked ideas rather than a story. This Greek edition is a textbook volume, so expect formal scientific vocabulary and sections that assume familiarity with earlier material.
Why read it
It offers a patient way to see familiar physical effects, like charged candy, as part of a larger picture, and to keep your curiosity about how things work.

Μπλε Λάμψεις από Καραμέλες Μια έμμεση απόδειξη της έλξης φορτίων με αντίθετα πρόσημα μπορούμε να δούμε με μια καραμέλα με γεύση π.χ. μέντας. Αν προσαρμόσετε τα μάτια σας στο σκοτάδι για 15 περίπου λεπτά και μετά πείτε σε έναν φίλο να δαγκώσει ένα κομμάτι της καραμέλας στο σκοτάδι, θα δείτε μια ασθενή μπλε λάμψη στο στόμα του φίλου σας σε κάθε δαγκωνιά. Όταν μια δαγκωνιά σπάει έναν κρύσταλλο ζάχαρης σε κομμάτια, κάθε κομμάτι θα καταλήξει πιθανότατα με διαφορετικό πλήθος ηλεκτρονίων. Υποθέστε ότι ένας κρύσταλλος σπάει στα κομμάτια A και B, με το A να καταλήγει με περισσότερα ηλεκτρόνια στην επιφάνειά του απ’ ό,τι το B (Σχ. 21.1.4). Αυτό σημαίνει ότι το B έχει θετικά ιόντα (άτομα που έχασαν ηλεκτρόνια προς το A) στην επιφάνειά του. Επειδή τα ηλεκτρόνια στο A έλκονται ισχυρά από τα θετικά ιόντα στο B, κάποια από αυτά τα ηλεκτρόνια μεταπηδούν διαμέσου του διάκενου μεταξύ των κομματιών. David Halliday.For some languages the translators left the Freudian precedent in, and Resistance gathers force.

The universe does not require divinity to govern its immense complexity.
There is no God-Creator, but there is the Cosmos, which creates suns, planets and living beings. There is no omnipotent God, but there is the Universe, which governs the fates of all celestial bodies and their inhabitants. There are no sons of God, but there are mature and thus rational and perfect sons of the Cosmos. There are no personal gods, but there are elected leaders of planets, solar systems, stellar groups, milky ways, islands of ether and the whole Cosmos. There is no Christ, but there is a brilliant man and a greater teacher of mankind.
Cosmos · Carl Sagan
The question a physicist can ask but equations cannot answer.
Even if there is only one possible unified theory, it is just a set of rules and equations. What is it that breathes fire into the equations and makes a universe for them to describe? The usual approach of science of constructing a mathematical model cannot answer the questions of why there should be a universe for the model to describe. Why does the universe go to all the bother of existing?
A Brief History of Time · Stephen W. Hawking
The night the ocean itself began to give off light.
While sailing a little south of the Plata on one very dark night, the sea presented a wonderful and most beautiful spectacle. There was a fresh breeze, and every part of the surface, which during the day is seen as foam, now glowed with a pale light. The vessel drove before her bows two billows of liquid phosphorus, and in her wake she was followed by a milky train. As far as the eye reached, the crest of every wave was bright, and the sky above the horizon, from the reflected glare of these livid flames, was not so utterly obscure as over the vault of the heavens.
The Voyage of the Beagle · Charles Darwin
