Professor Zwiebach has not thoroughly proofread these notes but believes they will be useful to people that want to know what goes on during lecture and what material gets covered. Don't show me this again. This is one of over 2, courses on OCW. Explore materials for this course in the pages linked along the left.

What we perceive as particles are actually vibrations in loops of string, each with its own characteristic frequency. String theory originated as an attempt to describe the interactions of particles such as protons. It has since developed into something much more ambitious: an approach to the construction of a complete unified theory of all fundamental particles and forces. Previous attempts to unify physics have had trouble incorporating gravity with the other forces. String theory not only embraces gravity but requires it. String theory also requires six or seven extra dimensions of space, and it contains ways of relating large extra dimensions to small ones.

String Theory and Particle Physics: An Introduction to String Phenomenology

Particle physics also known as high energy physics is a branch of physics that studies the nature of the particles that constitute matter and radiation. Although the word particle can refer to various types of very small objects e. In current understanding, these elementary particles are excitations of the quantum fields that also govern their interactions. The currently dominant theory explaining these fundamental particles and fields, along with their dynamics, is called the Standard Model. Thus, modern particle physics generally investigates the Standard Model and its various possible extensions, e.

Cosmology and Particle Physics

In particle physics , an elementary particle or fundamental particle is a subatomic particle with no substructure, i. Ordinary matter is composed of atoms , once presumed to be elementary particles— atomos meaning "unable to be cut" in Greek—although the atom's existence remained controversial until about , as some leading physicists regarded molecules as mathematical illusions, and matter as ultimately composed of energy. Via quantum theory, protons and neutrons were found to contain quarks — up quarks and down quarks — now considered elementary particles. Around , an elementary particle's status as indeed elementary — an ultimate constituent of substance — was mostly discarded for a more practical outlook, [1] pp1—3 embodied in particle physics' Standard Model , what's known as science's most experimentally successful theory. All elementary particles are either bosons or fermions.

 Она не клюнет на твою тактику разделяй и властвуй, - сказал Стратмор, подходя еще ближе.  - Отпусти. - Чатрукьян был совсем мальчишка. Ради всего святого, зачем вы это сделали.

Они мои лучшие клиенты. Беккер чувствовал, как ее глаза буквально впиваются в. Он решил сменить тактику: - Я из специальной группы, занимающейся туристами. Отдайте кольцо, или мне придется отвести вас в участок и… - И что? - спросила она, подняв брови в притворном ужасе. Беккер замолчал. Он опять перегнул палку.

 - Стратмор практически выгнал Чатрукьяна за то, что тот скрупулезно выполняет свои обязанности. Что случилось с ТРАНСТЕКСТОМ. Не бывает такой диагностики, которая длилась бы восемнадцать часов. Все это вранье, и ты это отлично знаешь. Скажи мне, что происходит. Сьюзан прищурилась. Ты сам отлично знаешь, что происходит.

Хейл сразу же растерялся, не зная, как истолковать примирительный тон коммандера, и немного ослабил хватку на горле Сьюзан. - Н-ну, - заикаясь начал он, и голос его внезапно задрожал.  - Первым делом вы отдаете мне пистолет. И оба идете со .

Энсей пользовался всеобщим уважением, работал творчески, с блеском, что дано немногим. Он был добрым и честным, выдержанным и безукоризненным в общении. Самым главным для него была моральная чистота.
