Biophysics is an interdisciplinary science that uses the methods of, and theories from physics to study biological systems.[1] Biophysics spans alllevels of biological organization, from the molecular scale to whole organisms and ecosystems. Biophysical research shares significant overlap withbiochemistry, nanotechnology, bioengineering, agrophysics, and systems biology. | Overview
Molecular biophysics typically addresses biological questions similar to those in biochemistry and molecular biology, but more quantitatively. Scientists in this field conduct research concerned with understanding the interactions …show more content…
Because most individuals are capable of creating new things for themselves, people have no difficulty understanding the process that man uses. But from this experience it is an easy mistake to assume that evolution uses a similar process to produce its successful forms. However the process for creating man-made objects and the process for producing biological objects are completely different.
For human endeavors of creation, the normal process is to first recognize the need for something new, identify what its function will be, and design it, before actually attempting to construct it. In all cases the builder, inventor, or engineer is limited to some degree in both the amount of time and the amount of resources that can be dedicated to achieving the goal. Given these constraints a person must be selective in how to utilize these resources. A person usually needs to be knowledgeable of science principles to create a new device, or at the very least a person must be able to follow designs and follow trade practices while constructing something …show more content…
It has many applications. Radar detectors use the Doppler effect to measure the speed of baseballs and automobiles. Astronomers observe light from distant galaxies and use the Doppler effect to measure their speeds and infer their distances. Physicians can detect the speed of the moving heart wall in a fetus by means of the Doppler effect in ultrasound. Bats use the Doppler effect to detect and catch flying insects. When an insect is flying faster than a bat, the reflected frequency is lower, but when the bat is catching up to the insect, as in Figure 15-7, the reflected frequency is higher. Not only do bats use sound waves to navigate and locate their prey, but they often must do so in the presence of other bats. This means they must discriminate their own calls and reflections against a background of many other sounds of many frequencies. Scientists continue to study bats and their amazing abilities to use sound waves.
