Our understanding of matter is still incomplete and the Standard Model of matter is still being validated and tested. Technology plays a substantial role in this.
Explain the role of technology in developing both the Standard Model of matter and our understanding in ONE other area of physics. (9 marks)
--- 18 WORK AREA LINES (style=lined) ---
Technology and the development of the Standard Model
→ Technology has played a significant role in developing the standard model of matter.
→ Scientists have used the technology of linear accelerators to accelerate a beam of electrons at stationary protons. Technology was then used to analyse the scattering patterns of the electrons which was inconsistent with protons being fundamental particles.
→ It was determined that protons were comprised of both positive and negative internal charges. This led to the discovery of quarks.
→ Further, the Large Hadron Collider (LHC) is technology which accelerates protons to speeds extremely close to the speed of light, and collides them with each other.
→ When these protons collide, their dilated kinetic energy is converted to mass in the form of new particles such as the Higgs Boson. This significantly develops our understanding of the standard model of matter.
Technology and Special Relativity
→ Another area of physics in which technology has played a vital role is special relativity.
→ Einstein’s prediction of time dilation has been validated by the Hafele-Keating experiment. Technology such as atomic clocks and high speed aeroplanes were used to demonstrate time differences recorded when atomic clocks were flown around the world.
→ In this instance, technology made it possible to validate Einstein’s predictions, improving our understanding of special relativity.
