20th-century Physicist Quotes
In our time of ever-increasing specialization, there is a tendency to concern ourselves with relatively narrow scientific problems. The broad foundations of our present-day scientific knowledge and its historical development tend to be forgotten too often. This is an unfortunate trend, not only because our horizon becomes rather limited and our perspective somewhat distorted, but also because there are many valuable lessons to be learned in looking back over the years during which the basic concepts and the fundamental laws of a particular scientific discipline were first formulated.
Strangely enough, many of the philosophical issues surrounding quantum mechanics are today being used to entice potential students into physics. As quantum computing and quantum communication become a commercial reality, tomorrow's students may find themselves routinely grappling with the same philosophical questions that challenged their forebears almost a century ago.
It seemed that fundamental physics was stuck. The particle physicists were smashing particles into each other with ever increasing force, trying to figure out how many quarks could dance on the head of a pin. The cosmologists were working with very few facts... on what seemed to me to be mainly religious grounds. And most of physics was still focused on pushing and pulling, on the material properties... rather than on its informational properties.... those that relate to order and disorder.
Although quantum theory involves the use of nonlocal states, such as wave packets and entangled states, there is nothing in the theory, or in the real world so far as it is accurately described by quantum theory, that corresponds to the sorts of instantaneous nonlocal influences which have often been thought to arise in the situation envisaged in the EPR paradox, or implied by the fact that quantum theory violates Bell inequalities.
Science is a special kind of explanation of the things we see around us. It starts with a problem and curiosity. Something strikes the scientist as odd. It doesn't fit in with the usual explanation. Maybe harder thinking or more careful observation will resolve the problem. If it remains apuzzle, it stimulates the scientist's imagination.
The existence of exotic dark matter particles outside the standard model of particle physics constitutes a central hypothesis of the current standard model of cosmology (SMoC). Using a wide range of observational data I outline why this hypothesis cannot be correct for the real Universe.
The circumference of earth at equator is 40,000 km and by dividing it with 24 hours (earth completes its rotation in a day), it comes out to 1,667 km. This reverse phenomenon happened at 60 degrees latitude because their jet plane managed a speed of 833.5 km which is half of circumference of the earth.
Knowledge or no knowledge, the intelligence community is obliged to furnish estimates to military planners, even if they're worthless and very possibly misleading. If you are one of those strange ducks trying to understand what this nuclear business is all about and read the respectable journals the CIA leaks information to, please don't get the idea this makes you a more respectable arm chair analyst than anyone else.
... we see a number of sophisticated, yet uneducated, theoreticians who are conversant in the LSZ formalism of the Heisenberg field operators, but do not know why an excited atom radiates, or are ignorant of the quantum theoretic deerivation of Rayleigh's law that accounts for the blueness of the sky.
