trace the development of the electron microscope and site some of its many uses. be sure to talk about why the scanning tunneling microscope is so significant. The Electron Microscope was first developed in 1931 and was used to magnify things that are extremely small. However, in 1938 the first practical microscope was developed. They have much more power than light microscopes and can…

Jimmys: Unit 1 Ch. 3 Reading Response — "Trace the development of the electron microscope and cite some of its many uses. Be sure to talk about why the scanning tunneling microscope is so significant." First of all an electron microscope is "a microscope that is similar in purpose to a light microscope but achieves much greater resolving power by using a parallel beam of electrons to illuminate the object instead of a beam of…
: Unit 1 Ch. 3 Reading Response — Doctors can inject patients with a radioactive element and use a special camera to take pictures of the internal workings of the organ. They use bone scans which can detect cancer 6 to 18 months sooner than x-rays can
: Unit 1 Ch. 3 Reading Response — The first prototype of an electron microscope was made in 1931 by German Engineers Ernst Ruska and Max Knoll. In 1839, the University of Toronto constructed the first practical electron microscope. Even today, the electron microscopes are based off of Ruska's first prototype. Biological materials (such as microorganisms and cells), a variety of large molecules, medical biopsy samples, metals…
: Unit 1 Ch. 3 Reading Response — Nuclear Medicine is a study of medicine that exploits radioactivity to diagnose certain diseases more accurately. Particles that are radioactivly charged are injected into an organ or body, these particles are called isotopes. These isotopes emit enough radiation to create an image that certain cameras can capture. The radiation can give a different and accurate picture of an organ and what might…
2Ne1: Unit 1 Ch. 3 Reading Response — The first electron microscope prototype was built in 1931. However, the first practical electron microscope was built in 1938.The microscope uses a beam of electrons to reveal the chemicals. The tunneling must be thin, in order to focus the beam. They have been refined since then but the basic design is still the same. The scanning tunneling microscope is a type of electron microscope that shows…
