An ultramicroscope is a microscope with a system that lights the object in a way that allows viewing of tiny particles via light scattering, and not light reflection or absorption. ... In discussions about light scattering, the converging beam is called a "Tyndall cone".

The ultrastructure of cells. Cells are the building blocks of all living organisms. ... The ultrastructure of a cell is its fine structure as revealed at high magnification. Animal, fungal and plant cells all contain structures specialised for particular functions called organelles .

A travelling microscope is an instrument for measuring length with a resolution typically in the order of 0.01mm. The precision is such that better-quality instruments have measuring scales made from Invar to avoid misreadings due to thermal effects.

Atencia et al. (2009) designed a device termed “the microfluidic palette,” which is capable of generating multiple spatial chemical gradients simultaneously inside a single chamber. While those designs allow generation of complex gradient patterns, they are limited to the creation of a pattern in a single chamber.

Another principle of physics is that Light and Electricity are the SAME THING. Electricity is just Light guided along wires. (Sort of.) But this "guiding" of light along the wires makes it slow down little.

Beginning as early as the 1930s, scientists were able to see at the nanoscale using instruments such as the scanning electron microscope, the transmission electron microscope, and the field ion microscope. ... These microscopes make use of tiny but exact movements to enable precise mechanical scanning.

The basic principle of interferometry is this: take two telescopes, separated by some distance, and observe an object simultaneously with both telescopes. Light comes from the object as a wavefront, like ripples in a pond created by splashing ducks.

A very small living organism visible with a microscope is called a microorganism, or a microbe. Microbes include viruses, bacteria, archaea, fungi, plants like algae, and protozoa, among others.

Thus, the three principles of experimental design are: replication, to provide an estimate of experimental error; • randomization, to ensure that this estimate is statistically valid; and • local control, to reduce experimental error by making the experiment more efficient.

visible light. The electromagnetic wave that is used in a microscope is the visible light. The microscope is an instrument used to view minute organism that cannot be seen by the naked eye. It is used to magnify microorganism to be viewed.

In 1993 an international group of six scientists, showed that perfect teleportation is possible in principle, or at least not against the laws of physics. More recently scientists both in the US and China have been trying. ... We are still working out how to teleport photons.

Voltmeter works on the principle of Ohm's law, which states that the voltage across a resistance is directly proportional to the current passing through it. In order to implement it in real time, we form the construction of a galvanometer, such that a coil is suspended in a magnetic field.

In 1868, T. H. Huxley described protoplasm as the “physical basis of life”. Protoplasm is a clear, colorless and jelly-like substance which seemed to make up the contents of the cell. It was also described as “substance of life” or “living material”.

Cells are significant as they are the very basis of life. In 1839, scientists Theodor Schwann and Matthias Schleiden developed the tenets of classical cell theory, stating that: All organisms are made up of one or more cells. Cells are the fundamental unit of life.

Plane mirror can used to make periscope because periscope is a useful example of law of reflection at work its important that your mirror are placed at 45 degree angle because light always reflects away from mirror at a same angle that it's hit it.
