The best optical microscopes can see structures in the 200 – 400 nm range, at their limits of resolution.
The STM can “see” structures on the order of 0.1 nm —another SPM, the AFM—can distinguish things on the order of 100 nm .
Optical microscopes are “diffraction limited”—the wavelength range of visible light (400-750 nm) sets the size of the smallest thing that can be imaged: ~ 400 nm.
Scanning Probe Microscopes don’t use visible light—they depend on measuring intermolecular ....etc

Human beings extract a lot of information about their environment using their ears. In order to understand what information can be retrieved from sound, and how exactly it is done, we need to look at how sounds are perceived in the real world. To do so, it is useful to break the acoustics of a real world environment into three components: the sound source, the acoustic environment, and the listener:

1. The sound source: this is an object in the world that emits sound waves. Examples are anything that makes sound - cars, humans, birds, closi ....etc

Latest Invention: Acoustic Ear-scanning Technology to Help Avoid Theft



Researchers managed to come up with a technology that could protect portable devices such as iPod and mobile phones from theft.
Their latest invention uses the acoustic fingerprint of the ear, which makes it impossible for other people to operate the device. Such technology could be also used to improve the safety features of bank accounts and passports.
Scientists found that it is possible to identify a person by the distinctive sounds ....etc
