The study of biomechanics ranges from the inner workings of a cell to the movement and development of limbs, to the mechanical properties of soft tissue, and bones.
Radio telescope. A radio telescope is a specialized antenna and radio receiver used to receive radio waves from astronomical radio sources in the sky in radio astronomy. Radio telescopes are the main observing instrument used in radio astronomy, which studies the radio frequency portion of the electromagnetic spectrum emitted by astronomical objects, just as optical telescopes are the main observing instrument used in traditional optical astronomy which studies the light wave portion of the spectrum coming from astronomical objects.
A radio telescopes collects and focuses radio waves to allow astronomers to see the universe in an entirely different way than that afforded by visible light. Figure 5.25 shows the puzzling galaxy Centaurus A. This is a rollover image showing both the optical view (yellowish image) and a radio view (greenish).
