A microscope (from the Ancient Greek: μικρός, mikrós, "small" and σκοπεῖν, skopeîn, "to look" or "see") is an instrument used to see objects that are too small for the naked eye. The science of investigating small objects using such an instrument is called microscopy. Microscopic means invisible to the eye unless aided by a microscope.
There are many types of microscopes. The most common (and the first to be invented) is the optical microscope, which uses light to image the sample. Other major types of microscopes are the electron microscope (both the transmission electron microscope and the scanning electron microscope), the ultramicroscope, and the various types of scanning probe microscope.
On October 8, 2014, the Nobel Prize in Chemistry was awarded to Eric Betzig, William Moerner and Stefan Hell for "the development of super-resolved fluorescence microscopy," which brings "optical microscopy into the nanodimension".
The first microscope to be developed was the optical microscope, although the original inventor is not easy to identify. Evidence points to the first compound microscope appearing in the Netherlands by the 1620s, with a likely inventor being Cornelis Drebbel. Counter claims include it being invented by Hans Lippershey (who obtained the first telescope patent) and what may be a dubious claim by Zacharias Janssen's son that his father invented the microscope and telescope.Giovanni Faber coined the name microscope for Galileo Galilei's compound microscope in 1625 (Galileo had called it the "occhiolino" or "little eye").

Confocal microscopy | confocal microscope principle - lecture on confocal fluorescence microscopy principle and advantages of using confocal microscope. Confocal microscopy offers a few benefits over traditional widefield optical microscopy, including the ability to control depth of area, removing or reduction of historical past knowledge away from the focal plane (that leads to picture degradation), and the potential to gather serial optical sections from thick specimens. The basic key to the confocal process is using spatial filtering approaches to do away with out-of-focus mild or glare in specimens whose thickness exceeds the on the spot aircraft of focus. There has been a large explosion in the fame of confocal microscopy in recent years, due partly to the relative ease with which hig...
This is a video on some of the different microscope cameras you can purchase these days. I will be doing a more in depth video on cameras, the features, the differences between sensors and more later. Along with a review of the microscope and information on Barlow lenses and different magnification for getting the best working distance for your needs. The 720P camera will record video if your using USB to your computer and the software. It just doesn't record video without the computer to the SD card, but video recording is possible. Auto white balance and exposure with the ToupTek software didn't work good with the MU300, this may be the same with the 720P recording over USB but I didn't test that. The built in firmware does good auto adjustments, so if you record with a HDMI capture dev...
The Solar System furnishes the most familiar planetary architecture: many planets, orbiting nearly coplanar to one another. We can examine the composition and atmospheres of the Solar System planets in detail, even occasionally in situ. Studies of planets orbiting other stars (exoplanets), in contrast, only begin to approach the precision of humanity's knowledge of Earth five hundred years ago. I will describe a two-pronged approach to the study of exoplanets. One approach involves time-intensive investigations of individual planets to eke out bulk density or single molecules in the planetary atmosphere. Another involves studies of the ensemble properties of planetary systems, and addresses the question of a "typical" planetary system in the Milky Way. In an era with thousands of exoplanet...
Hello, I wanted to put together a basic overview of magnification - talking about loupes and what is a dental operating microscope and its components.

Description: Light has properties of particles and waves. Understanding the wave nature of light is essential to understanding the workings of a microscope. This lecture describes Huygens Wavelets, constructive/destructive interference, and diffraction.
pt. 1 dancing microorganism with meditation sounds High quality and interesting videos of microorganisms in a water drop, such as ornamental algae, diatoms, tardigrades, rotifers, ciliates, Paramecium, amoeba and other protozoa. Under the microscope the behavior of microbes will be recorded in Full HD, all unicellular and multicellular organisms. Exciting observations for school, university and to education!

Don’t wanna hear that’s what he said and she said
That kind of garbage rolls on down the hill
Don’t wanna know about what he knows and she knows
That kind of work, it don’t pay my bills
A million dollars couldn’t pay the toll
I dropped my hammer and I’m down the road
You try to follow me so close behind
Soak up the magic and away I ride
There’s a great deal that you don’t know
There’s a great depth that you can’t go love
Now there’s a great deal that you don’t know
Under the microscope I will float, I will float
You got some scruff and it’s time for shavin’
Your hairs too long, better start behavin’
You keep on pushin’ on me night and day
But I’ll be risin’ from that grave
A billion dollars couldn’t pay the toll
I dropped my hammer and I’m down the road
You try to follow me so close behind
Soak up the magic and away I ride
There’s a great deal that you don’t know
There’s a great depth that you can’t go love
Now there’s a great deal that you don’t know
Under the microscope I will float
I will float, I will float, I will float
I will float, I’ll float
I will float, I will float
I will float
