    large disk with holes on it, which spun in front of an object while a photoelectric cell recorded changes in light. Depending on the electricity transmitted by the photoelectric cell, an array of light bulbs would glow or remain dark. But Nipkow’s mechanical system could not scan and deliver a clear, live-action image. Many inventors hoped to perfect this. In 1921, a 14-year-old Mormon from Idaho named Philo Farnsworth came up with an idea. While mowing hay in rows, Philo realized an electron beam

    blurry. Then, I remember I had a pencil with an eraser. I turned that pencil around so the eraser was pointing directly towards the paper and the lead was pointing to the ceiling and I erased my error like no man had erased an error on an exam before. Quickly my mistake vanished and I was able to write down the correct answer. A couple of months later I got my score. I had passed the exam. The pencil had once again saved the day and I began to appreciate and love the pencil. Am I different from any other

    concepts of “effective” and “mechanical” in logic and mathematics. Both Turing and Church reached the hypothesis independently and in different forms. But both forms confront similar issues and the general form is known as the ‘Church-Turing thesis’. In general, the thesis asserts that a machine can execute all processes that are ‘mechanical’[1]. Clearly, there is some ambiguity in this statement. What is meant by mechanical? What is meant by machine? ‘Mechanical’ (or ‘effective’ as Turing sometimes

    A pencil Listeni/ˈpɛnsəl/ is a writing implement or art medium constructed of a narrow, solid pigment core inside a protective casing which prevents the core from being broken or leaving marks on the user’s hand during use. Pencils create marks by physical abrasion, leaving behind a trail of solid core material that adheres to a sheet of paper or other surface. They are distinct from pens, which instead disperse a trail of liquid or gel ink that stains the light colour of the paper. Most pencil

    Physics Waves Lab SL Introduction: This lab will investigate the properties of mechanical waves such as a longitudinal wave, focusing on the question: Does a change in the frequency of a wave result in a significant and convincing change in the speed of the wave? Hypothesis: Changing the frequency of the wave will not result in a change in speed because the wavelength will change proportionally as in theory. Student Designed Investigation Procedure/ Planning Procedure: 1.     Three students

Incorporating the low hum of the ventilation system, I compiled the sounds into a neat musical score by drawing the sounds as they occurred over a twenty-second time span. I then titled my piece "Twenty Seconds of Music 20A
