"Theoretical physicists use mathematics to describe certain aspects of Nature. Sir Isaac Newton was the first theoretical physicist, although in his own time his profession was called "natural philosophy". ..."

"Relativistic quantum field theory has worked very well to describe the observed behaviors and properties of elementary particles. But the theory itself only works well when gravity is so weak that it can be neglected. Particle theory only works when we pretend gravity doesn't exist. ..."

"In the 18th and 19th centuries, Newton's mathematical description of motion using calculus and his model for the gravitational force were extended very successfully to the emerging science and technology of electromagnetism. Calculus evolved into classical field theory. ..."

" The US military plans a portable device that uses focused sound waves to treat troops bleeding internally from wounds sustained on the battlefield. Ultrasound can seal ruptured blood vessels deep within the body without the need for risky surgery. The lightweight device has to be designed so that soldiers can operate it with minimal training. Blood loss from wounds to the extremities is regarded as a major, preventable cause of battlefield death. ..."

"It has recently been argued that anthropic reasoning applied to inflation theory reinforces the prediction that we should find ourselves part of a large, galaxy-sized civilisation, thus strengthening Fermi's paradox concerning "Where are they?" Furthermore, superstring and M-brane theory allow for the possibility of parallel universes, some of which in principle could be habitable. In addition, discussion of such exotic transport concepts as "traversable wormholes" now appears in the rigorous physics litera..."

"If an artificial or electromagnetic energy source is interacting with the natural cycle of plants, it is perfectly natural to assume the effect is verifiable at the microscopic level. In 1988 Andrews and Delgado sent plant samples from crop circles, together with controls, to Signalysis laboratory in Stroud, England. The samples were processed by Kenneth and Rosemary Spelman in accordance with a procedure approved in the German Government's "Pharmacopoeia for Homeopathy" for spagyric preparations- a process norm..."

"While the cutting techniques of the ancient pyramid builders have been a continuing topic for debate, they have not received the same attention and controversy as the proposed methods that were used to lift and transport huge cyclopean blocks of stone. While Egyptologists and orthodox believers in primitive methods argue that the huge blocks were moved and put into place using only man power, experts in moving heavy weights using modern cranes throw doubt on the subject...."
