The Intricacies of a Compound Microscope
Have you ever used a compound microscope? Your first thought may be to answer "no" but chances are if you had Biology in high school or college that you have used a compound microscope. What do you remember about this microscope? You may remember what it looks like but can you recall how it worked? If not, this article is for you!
A compound microscope uses light to illuminate the sample or object so that you can see it with your eye. It has two lenses that are used in combination to give you a greater view of the sample or object. One lens is called the objective lens and the other is called the eyepiece lens. The one nearest the sample you are looking at is called the objective lens. This is the lens that sticks out at the bottom and is the one you can change the magnification with. The eyepiece lens is mounted in the microscope cylinder nearest your eye. The combination of these two lenses give you your magnified image and magnification abilities.
There are many uses for the compound microscope. It is an essential tool in the creation of medicines and cures for diseases. It is also used for research in the field of bacteria and other biology. The compound microscope is used to examine cells, bacteria, and other organisms. It is also widely used in teaching about the world around us in schools across the world.
Who made the first compound microscope? A Dutch spectacle maker noticed that when he put two lenses together that magnification was greatly increased. He may have been among one of the first creators but the beginning of the invention is commonly contributed to Galileo in 1610. Galileo had heard of lenses being used in combination and made an instrument with a focusing device. Anton van Leeuwenhoek, considered the father of microscopes, was working in a store that made magnifying glasses and created ways to increase the magnification by grinding smaller and more powerful lenses.
Then he began building microscopes and was among one of the first people to see bacteria and cells up close. Others have contributed to and upgraded the compound microscope to the modern version we have today. A modern compound microscope can magnify a sample or object up to two thousand times.
The compound microscope has enabled scientists to cure many diseases over the years. Without the invention of the compound microscope, many diseases such as smallpox, measles, and others would still be prevalent in our society today. Learning about cells and micro organisms using a compound microscope gives scientists the tools to cure disease and learn about the miracle of the human body.
Technology advances at such an astronomical rate that it's hard to keep up - take advantage of these advances with some light hearted reviews of devices designed to make our life easier. Here we look at microscopes: http://www.microscopes-reviewed.com
Acoustic Transducers for High Altitude Balloon Control
Using acoustic transducers it maybe possible to create a small region of thicker air underneath a blimp and use that patch as a platform of air to float on while blowing ever so slightly low pressure air underneath the blimp like a hover craft. Although this idea sounds like a long shot it can be done by use of a screen, which shoots the directed frequency waves into the waves created by the acoustic transducers.
Issues with Aerial Fire Fighting
A few years ago I visited the Wyoming Contractor, which used WWII aircraft to fight such fires. I was amazed that such old aircraft were not in museums but rather in flying condition and used for dropping phoschek on fires.
The Fall and Fall of the p-Zine
Para Trooper Gliders With Angle of Attack Motor or Crank
Para Trooper Gliders were very popular in WW II, they were used by both the Axis and Allied Forces. Some of these gliders were huge in size and the Germans had one which had took three bombers to get it off the ground along with two-four rockets used in take off.
Shamans and Their Documented Abilities
Many Shamans will go into a sweat house to get their premonitions, here is a make shift sweat house used by such native Indians;http://www.nativeradio.
Locusts To Help Make Energy From Bio Waste, part II
If we take the menace, nuisance and destructive Locust, we can create a win/win situation by and allowing it to survive and happily eat our bio-waste filling up our dumps. Then as it progresses and digests the food it will create energy.
Super Volcano: Can The Disaster Be Prevented?
It maybe possible to apply a rogue wave theory and some mathematical formulas of fluid dynamics to the problem of superplumes (theory) of volcanic activity to get them to erupt outside areas of high populations. This would be done by triggering events into the liquid magma underneath the surface.
Mini Robots Grid Meteorite Search
We need very much to study meteorites more, but we need more sampling to get this done. One way to do this is to go out hunting for meteorites.
Cloaking the Postage Stamp Modern Aircraft Carrier
By using a special coating on the deck of an aircraft carrier and a projector on the top of the tallest communications mast facing down, we could project the image of the ocean onto the deck like a giant IMAX theatre screen. Although this sounds like a daunting task, it isn't really.
Rover Stuck on Mars?
NASA scientists had to solve a relatively common problem hear on Earth with the Rover on Mars. What do you do when you are stuck in the sand? Anyone who has ever raced off road or owned a 4X4, dune buggy or ATV understands these issues.
Tsunami warnings by 2006
Experts from the United Nations and Indian Ocean countries agreed to set up a tsunami warning system to prevent a repeat of the catastrophe that struck on December 26, Unesco said.A fully functioning system that detects undersea earthquakes and broadcasts warnings to coastal communities is expected to be in place by the end of 2006, said Patricio Bernal, executive secretary of Unesco's Intergovernmental Oceanographic Commission, on Tuesday.
The Bermuda Triangle and Antarctica
The art or science of metallurgy is vital to the social structures surrounding all esoteric beliefs. They are the most tangible items of the cosmic soup that are possibly drawn to certain Earth Energy Grid locations as we shall see.
Making Diamonds Using The Earth
We can make diamonds using the Earth's inner forces, extreme pressure and heat. We simply send Carbon Blocks in tubes, which have been drilled into the Earth's Mantle.
Ancient Navigation and Mapping
DR. SENTIEL ROMMEL:As part of the research team that sought to know how advanced the ancient navigational equipment and computers or astrolabes were, this man deserves credit he has not received; although it might be that credit would come in the form of ridicule such as was directed at Barraclough Fell.
Fire Escape System Concept
What if in the event of a fire the building system started putting out instructions using sound waves of the best possible escape route? Using the pictures on the wall and windows to guide trapped occupants and guide them to the safest exit? It is all possible now due to an old technology which is now being used thru a transfer into the public domain. Smoke inhalation is the number one cause of death in fires.
How to Build a Mechanical Bullet Which Turns
A Mechanical bullet, which will turn in flight is well within our technical capabilities. The premise is to have a bullet, which is preset to turn a corner can be achieved thru a small gear setting on the bullet or a preset finger on the barrel or in the chamber which can be dialed in prior to discharge.
51 Easy, Eco-Friendly Ways You Can Help Sustain Planet Earth

Organic Decoy Devices for Warfare (ODDW)
We can genetically modify a rat to be the same body temperature as a humans, then parachute in several thousand rats into enemy territory. These rats will pick up the enemies advanced warning and intrusion sensors by way of heat signature.
How Body Piercing Works -- The Ins and Outs of this Cutting Edge Process
Body piercing (defined as any piercing beyond the standard earlobe piercing) has become such a popular form of body modification that between five and ten percent of the population of the United States has indulged in at least one form of it at some time in their lives. In most cases, once a person gets a body piercing, they follow the first one with more.
Creating Artificial Time in a Vacuum With Pulsed Lasers
Keying off a very interesting concept confined within Static Quantum Theory and looking for the edge of time or the end of energy or the Quantum Borderline or virtual boarder of nothing. One might use the idea of pulsed lasers created in a defined confined area of a vacuum to create a singularity of a pulsed laser, whose immediate disruption pulses of the singularity which would follow would reach the end of the confinement area faster than the light which would in fact be created and then this traveling disruption would trigger another pulsed laser reciprocal event on the far side of the confinement whose pulsed laser would send it's disruption of the event to occur to the original point of the first singularity of the original laser or starting point, which would trigger the turning off of the first laser before it created the event of singularity or light.
