Reflex sight

On October 4th, 1888, George Eastman had patented a new camera. This camera was incredibly easy to use, easy to carry, and affordable to middle class; costing about twenty five dollars for the camera and ten dollars for film and development. The camera was a black leather box about sixteen by nine by eight centimeters. It was handheld and had a fifty-seven millimeter lens. (Steidl 9) This camera was the Kodak Camera. In 1900 Eastman now came out with the Brownie Camera. It was a six-exposure…

#Hasselblad is designed as a specialist studio and field camera [写真挿入] Leica, Hasselblad, Rollei, and Linhof are my favorite adoring cameras. Especially, Hasselblad seems to have a strong image of a high fashion model. Viewing through a waist-level finder and looking at a photo model symbolize a typical stereotype of a professional photographer. # History of Hasselblad Hasselblad was established in Sweden. It has an origin of an aerial camera during the World WarⅡ and was officially…

Epilepsy is a neurological disorder that causes seizures, and it affects approximately 1.5% of the population (CDC). The roots of this disorder can be traced back to almost 2,000 B.C, beginning with texts from the Assyrian and the Babylonian empires (Highlights). Written in approximately 400 BC, “On the Sacred Disease” was a work by the Hippocratic Corpus in which doubt was cast on epilepsy as a supernatural or divine disorder, and epilepsy was first remarked as a natural and earthly disorder…

to outgrow the normal startle response. The National Tay-Sachs Allies Diseases regards the “normal startle response” as, “normal reflex for an infant when he or she is startled or feels like they are falling. The infant will have a "startled" look and the arms will fling out sideways with the palms up and the thumbs flexed.” (NTSAD). If a child does not outgrow this reflex, it is a early sign of a number of problems that will be more noticeable in the future. By two months the child will begin…

He questioned what would happen if after conditioning, the bell (CS) occurred repeatedly without the food(US)? Would the dog still salivate(CR)? It seemed that the dog salivated less and less as time went on without the food(US). This reaction is known as Extinction. Gradually the dog stopped salivating to the sound of the bell and became extinct. Extinction weakens the CR while Acquisition strengthens it. However, when the bell was again paired with the food (US) he started to…

I was examined again a few moments later and was still stuck at 8.5 centimeters. Unhappy with how slow things were progressing, the doctors decided to induce my labor. The nurse injected another substance into my IV and we continued to play the waiting game. An hour later the doctors came rushing in, bubs heart rate dropped dramatically. The medicine they administered stressed the baby out and caused her heart rate to slow. To bring it back up they gave me a shot of adrenaline. We all stared…

over their body. They have poorly coordinated swipes when they reach for an object in front of them, this is known as prereaching. Along with not being able to control their reflexes, they struggle controlling their movements. Although their grasping reflex is extremely strong, they don’t improve the accuracy of their reaching until about three or four months. The Rockin’ Roller can be used for children right after birth, but with their reaching skills not fully developed, I would recommend it…

Ruger 10/22 Shooting cans with a .22 rifle is very satisfying, and is the first step many shooters take into sports like hunting, recreational shooting and competitive shooting. Few things are more satisfying as a kid than lining up a can in the sights of a .22 rifle, slowly squeezing the trigger, and embracing the unexpected buck of the rifle as it fires and making a can jump with a direct hit. Time changes, as with most things, ideas and philosophies progress with each new generation. It…
