... theory is good for you because studying it expands your mind... Specific technical knowledge, though useful today, becomes outdated in just a few years. Consider instead the abilities to think, to express yourself clearly and precisely, to solve problems, and to know when you haven’t solved a problem. These abilities have lasting value. Studying theory trains you in these areas.Michael Sipser

Science is a river with two sources, the practical source and the theoretical source.Alfred North Whitehead

If you wish to learn from the theoretical physicist anything about the methods which he uses, I would give you the following piece of advice: Don't listen to his words, examine his achievements. For to the discoverer in that field, the constructions of his imagination appear so necessary and so natural that he is apt to treat them not as the creations of his thoughts but as given realities.Albert Einstein

You may be theoretically rich but practically poor.Pushpa Rana

If I keep observing the uranium, which means a little more than keeping my eyes on the pot on my desk and involves something akin to surrounding it with a whole system of Geiger counters, I can freeze it in such a way that it stops emitting radiation. Although Turing first suggested the idea as a theoretical construct, it turns out that it is not just mathematical fiction. Experiments in the last decade have demonstrated the real possibility of using observation to inhibit the progress of a quantum system.Marcus Du Sautoy

The desired shape your dreams take is directly proportional to the practical presentation of the theoretical skills that you have learnt.Israelmore Ayivor

Theories might inspire you, but experiments will advance you.Amit Kalantri

Theory is relevant to you because it shows you a new, simpler, and more elegant side of computers, which we normally consider to be complicated machines. The best computer designs and applications are conceived with elegance in mind. A theoretical course can heighten your aesthetic sense and help you build more beautiful systems.Michael Sipser

Before we aspire after theoretical perfection in the amelioration of our political state, it is necessary that we possess those advantages which we have been cheated of, and which the experience of modern times has proved that nations even under the present conditions are susceptible.Percy Bysshe Shelley

The abject impulse is inalienably connected with the feminine, specifically the maternal. As it forms out of the undefined morass of relations, surfaces and currents that existed before the Oedipal or mirror-stage coordinated them, the subject seems built around a primal sense of loss. The developing sense of the limits of the body is focussed on those holes in it's surface through which the outside becomes inside and vice versa: the mouth, anus, genitals, even the invisibly porous surface of the skin. It was the mother's body that was most connected with these crossing-points, as it fed and cleaned the undefined infant body. The sense that boundaries and limits are forming around this permable flesh is interpreted then as the withdrawal or even loss, of intimacy with the body of the mother, firstly in the increasing distance of the practical hygiene operations it performs and secondly, more remotely, beyond that in it's archaic ur-form as the body through which the child entered into the world.Nick Mansfield

Ironically people will thank a deity for "letting" them win a race, but blame a "witch" if they stumble, look for the nearest suspect, and kill them. Why not blame the deity? Why not accept the setback as easily as they accept the victory/ Time people grew up some, I think - and stopped looking for theoretical "somebodies" to blame for their own misfortunes.Christina Engela

A theoretical grounding in agronomy must, therefore, include knowledge of biological laws.Trofim Lysenko
