Stanford Continuing Studies :: Course :: PHY 24 - 32 W
This Stanford Continuing Studies course is a collection of classes and lectures that is the minimalist approach to Theoretical Physics. A student following this curriculum would achieve a solid understanding of Modern Physics in an optimized manner. It is the minimum that is required to begin to understanding theoretical physics. In Professor Susskind's words ... "A number of years ago I became aware of the large number of physics enthusiasts out there who have no venue to learn modern physics and cosmology.

Christmas Lectures 1977: The Planets : Ri Channel
What exists beyond Earth? Over six lectures presented in 1977, American astronomer and cosmologist Carl Sagan explores the vast expanse of space that surrounds the third planet from the Sun. Life on Earth Where at first we could only discern the size of our planet and some knowledge of its atmosphere and configuration, the evolution of planetary exploration has revealed not only intricate details of Earth’s climate and geology, but a multitude of stars and planets besides our own. Beginning with a closer look at the world we inhabit, Sagan explores of the diversity of life on our own planet and the building blocks behind it, before questioning whether the same organic chemistry is occurring on planets in the outer solar system.

Η θεωρία των διανυσμάτων που αναπτύξαμε στο Κεφ.1 γενικεύεται στη θεωρία διανυσμάτων στον τρισδιάστατο χώρο. 2.1 Περιγραφή διανυσμάτων στο χώρο 2.1.1 Γεωμετρική περιγραφή: Τα διανύσματα περιγράφονται σαν προσανατολισμένα ευθύγραμμα τμήματα. Δύο διανύσματα θα θεωρούμε ότι είναι ίσα, εάν έχουν το ίδιο μήκος και την ίδια κατεύθυνση. Με άλλα λόγια θα θεωρούμε ένα διάνυσμα αμετάβλητο όταν κινείται παράλληλα προς τον εαυτόν του. 2.1.2 Αλγεβρική περιγραφή: Ένα διάνυσμα στον χώρο περιγράφεται σαν μια διατεταγμένη 3-άδα (α,β,γ), όπου (α,β,γ) το σημείο που αποτελεί το πέρας του

Practical Physics
This website is for teachers of physics in schools and colleges. It is a collection of experiments that demonstrate a wide range of physical concepts and processes. Some of the experiments can be used as starting-points for investigations or for enhancement activities. Many have links to carefully selected further reading and all include information and guidance for technicians. Physics is a practical science.A step-up transformer
Using lamps and meters to compare the voltages in the primary and secondary coils of a transformer. Demonstration meters, with AC dials (1 A, 5 A, 5 V), 2 C-cores and clip, pair of
Shows the basic principle of any transformer: a change in current in the primary coil will induce an e.m.f. (voltage) in the secondary coil. For each student group Galvanometer, sensitive to e.g. 3.5–0–3.5 mA, 10 ohm resistance C-cores, laminated iron, 2
