Before Spring Break: Hiding In The Light

The camera obscura catches an image through a lens and it is projected in a darkened chamber. The portable camera obscura invented in the 17th century could be moved around and used both indoors and outdoors. It had an adjustable lens and a slanted metal mirror which projected the image onto a translucent screen. By moving the lens forward and back, the image could be focused on the screen. It should be noted here that if Vermeer placed such a portable camera obscura on the table, the height of the lens would correspond to the height of the windowsill in Vermeer’s home, which is the same level of the viewing points in many of his paintings (Koningsberger 139). Therefore, Vermeer would have had both the technology and the right mindset of the day to be aided by the camera obscura.

There are many things we can identify in our favorite novels. In my book The Hidden Summer, there are themes, the author's purpose, and conflict. The protagonist in this novel is Nell. The setting takes place in an abandoned mini golf course. The story begins with a conflict, which is, Nell and her best friend Lydia are not allowed to see each other because their moms told them that they are forbidden to do so. They aren't too happy about this news but as best friends, they'll find a way to meet each other no matter the obstacles.

Spring break is supposed to be one of the happiest times of the year: families go on vacation, students and employees can finally relax after months of hard work, and the horrible cold months are finally turning into beautiful, lively new ones. This is how most people would describe spring break, but for me and my family in April of 2010, this was not the case.

The importance of spring break is for students have a break of school,and when they enter school they could begin with their finals. In my spring break i liked bounding with my family and, visit the place we traveled.

Isaac Newton observed that light traveled in a direct line which led him to think that light was made up little particles. Although when you shine two lights opposite from each other they did not collide and scatter everywhere. He saw that they went through each other which made him confused. He also saw that when the light hit the water it bent, (This 'bending of a ray of light' when it passes from one substance into another substance is called refraction). Even though he didn't completely understand light he still made extraordinary discovers like the one I listed above.

Jan Vermeer was a Dutch painter who fascinated by the use of light in his paintings. “Unlike Caravaggio and Rembrandt, who used light for dramatic emphasis, Vermeer concentrated on the way light reveals each color, texture, and detail of the physical world” (Preble 307). Vermeer

I’m reading Horrible Science: Frightening Light it talks about the light that is blindingly obvious. It’s just sunshine and the light-bulb in your living room. The science of light is full of sizzling, squishy, horrid facts that teachers like to keep you in the dark. This book told me how lethal laser beams can sizzle human flesh, why dead bodies make ghostly glowing lights, how rattlesnakes can find you in the dark, why contact lenses were moulded from dead people’s eyeballs, how eclipses turn night into day, how stars have colours we can’t see, how to use light to zap enemy missiles. Through this story I learned many helpful lessons about the light.

Dark matter is the thing that makes it possible for galaxies to exist. When calculated why the universe is structured the way it is, it quickly became clear that there is just not enough normal matter. The gravity of the visible matter is not strong enough to form galaxies and complex structures 2. The stars would more likely be scattered all over the universe and not form galaxies. It is therefore known that there is something else inside and around them. Something that doesn't emit or reflect light; Something dark. Besides being able to calculate the existence of dark matter, humans can also see it, only partially. Places with a high concentration of dark matter bend light passing nearby. This leads scientists to believe that there is something there that interacts with gravity. Right now, there are more ideas about what

While comparing this to the total light emitted he found that the light out put per unit mass fell short by a factor of over 100 times more (Redd 2014), Fritz claimed that a large amount of matter was not being accounted for (Learner.org 2014). This was the first real evidence of the existence of dark matter (Redd 2014). Shortly after In the 1950s astronomers analyzed multiple spiral galaxies and predicted the material on the outside would move slower opposed to the material moving faster on the inside based on Newton’s laws (Grant 2013). Instead they had discovered stars in different locations within the galaxy’s travelled at the same velocity (Redd 2014). This defies Newton’s laws, unless there is another force that is interacting with the galaxies that we cannot see (Grant 2013). This is another indication that the galaxy’s contained more mass than was visible (Redd 2014), providing further evidence of the existence of dark matter, but the problem was how can you find something that isn’t there (Learner.org 2014).

Although it has not been proved it is thought that the artist [4] Caravaggio used lenses to create some of his works of art. The arrangement is they had help with lenses or concave mirrors. If someone stands outside bathed in light, an image could then be projected inside onto a wall or another surface. One more discovery made during this period of time was the use math, calculus to be specific. The use of calculus in architecture allowed building to be built taller and narrower. One example of such structures was the Sistine Chapel. One could argue the use of interior lighting could be another scientific

It is likely that many artists will have used a camera obscura to aid them in drawing, but because of the stories of the occult, or because they felt it was "cheating" in some way not many people would admit to using one. In 1764, the lens was being developed. The name lens comes from

In our universe, there is stars, galaxies and other they are made of protons and neutrons and also electrons bundled together into atoms. Most of the universe is it appears is made of something that we don't know about only when there was invisible substance is called dark matter that we did not know about it is 25% of all matters and there is another substance a force that can repel gravity it is known as the dark energy and it is made of 70% of all matter so that makes up 5% of matter of the universe. Dark Matter is different from Dark Energy, Dark Matter can not be seen with the light it is invisible but, according to NationalGeographic.com that “making dark matter impossible to detect with current instruments. But scientists are confident it exists because of the gravitational effects it appears to have on galaxies and galaxy clusters”. For Dark Energy scientist they don't know why, what, how do they know that Dark Matter exists in spaces, Dark Energy is way different from normal matter “dark energy has negative pressure, and it’s this negative pressure that makes gravity

I choose to do my experiential project on the camera obscura which essentially displays an image onto a wall or other surface to be viewed. The word “camera obscura” comes from the Latin term that means “dark chamber” which came from the practice of creating dark rooms that had a small pinhole that allowed light to enter and project an image from the other side of the pinhole into the room.

Dark Matter was first proposed by Fritz Zwicky in the 1930’s when he observed the motions of galaxies and he noticed that the amount of visible objects could not account for the observations he made. There had to be some “invisible” mass holding these galaxies together. It is known that 25% of our universe is made up dark matter versus 4% of the visible matter we know and interact with every day. The leading candidates for dark matter are MACHOs and WIMPS. Gravitational lensing is one of the ways we can infer the presence dark matter, since we cannot see it directly. With the discovery of dark matter, the standard model of physics no longer answers all the questions. For that, we need another model, called supersymmetry.

Cameras are involved with physics because they use visible light to capture a picture. Visible light is part of the electromagnetic spectrum. The electromagnetic spectrum contains different wavelengths and frequencies. The visible light spectrum is the part of the electromagnetic spectrum that humans can see. Specific wavelengths in the spectrum are represented by specific colors. This is how humans are able to perceive colors, through visible light. When a camera captures an image, it uses visible light to capture the different wavelengths. These wavelengths are seen as different colors which come together to create the image. Visible light is what allows the colors that create the image to be seen when the picture is captured.
