People take pictures to show their discovery, but others use different methods to explain what they saw. Back then; paper and pen were used for people to explain their discoveries. But fast forward to today’s society, a lot of people love to use a computer. Computer usage can be used for many things. But now, people all over the world (Ex: Students) use programs

They say that there’s a right tool for every job. In the case of spotting scopes, their job is to provide close-up visual access to anything on land while staying a safe distance away. Something of a cross between binoculars and a telescope, spotting scopes have uses from nature photography, bird watching, and even hunting. While a telescope is usually used at night to observe the stars, a spotting scope is meant only to be used during the day. When comparing a spotting scope to a telescope or a

through the glass lens and the different colours that make up white light refract at different angles. This causes the observer to see a rainbow around the image they are viewing. One way to counteract the effects of chromatic aberration is to use multiple compensating lenses. Another way to avoid chromatic aberration is to use a long object focal length this is the distance between the focus and the objective Another disadvantage is the difficulty of making the lenses. The objective lens need to have

based on our eyes being approximately 6-7 centimeters apart, which causes each retina to receive a slightly different image. Convergence is a binocular depth cue, involving both eyes concurrently moving inwards as the object moves closer towards the lens, in order to maintain focus on the object. The most simplest Gestalt principle is the gestalt principle, which involves the viewer perceptually grouping and separating features of a stimulus to stand out as an object (the figure) against a plainer

microscope and prepare a wet-mount slide? Hypothesis: A compound microscope is being used properly when the light source, nosepiece lens, and eyepiece lens work together to bring a magnified image to one’s eye. A wet-mount is properly prepared when a drop of liquid containing the sample is placed between the slide and a thin glass coverslip.

In 2010, Dr. Manu Prakash conducted a presentation for TedMed titled “Print-and-Fold”. Dr. Prakash’s research from Stanford University is based on bringing new technology to global health. In 2012, Dr. Prakash was awarded a grant from the Gates Foundation for his paper-folded microscope project. In addition, Dr. Prakash currently serves as a Bioengineering professor at Stanford University. In this presentation, Dr. Prakash discusses the lack of access that some countries have for microscopes. Thus

microscopy. To calculate a 3D- surface-model the lower and upper border of the depth of interest has to be determined, by focusing on these levels. Between these borders a level difference of five microns were chosen. In other words, after every scan the lens moves five microns from the sample away.

An heirloom from the saddlebag of a horse jiggled loose and fell to stony path—its fall broken by a dollop of manure. Soamy picked it out and looked through. Grey. Nothing came into focus no matter how far or near she held it to objects or the ants that scurried around her boot soles. “Broken,” she said, tossed the looking glass into the long grass and smeared the dirt from her fingers onto her hessian apron. She went on her way—died 52 years later without ever realising her opportunity. In that

mentioned in the writings of the two Roman philosophers, Seneca and Pliny. Apperantly, maginfiers weren't really used much until the invention of the spectacles. The oldest actual microscope was actually just a tube with a plate at one end and a glass lens at the other end. They magnified

the microscope. This lab showed me what materials and parts of the microscope I should use when examining an object. Introduction The microscope was invented by a father and son, Hans and Zaccharias Janssen. They were once looking at the lens of a magnifying glass and decided to put the lenses in a tube. When they looked through the tube, they noticed that the object underneath the magnifying lenses, was enlarged. That was the first invention of the compound microscope. Overtime, more advancements
