How do speedometers work? A: A speedometer is a gauge that measures the instantaneous speed of a vehicle. Speedometers became standard in all motor vehicles in 1910 Speedometers were created by the Croatian engineer Josip Belušić in 1855 Uses the rotation of the wheels to work When the cars engine turns over the drive shaft spins to turn the wheels The speedometer cable which is powered by the driveshaft also spins A magnet located inside the speed cup (made of aluminum) of the car spins at the…

The similarities and differences of Kinetics of a Particle: Work and Energy and Planar Kinetics of a Rigid Body: Work and Energy. Kinetics of a particle: work and energy shows the particle moving when forces are applied to it and produces work and energy. Meanwhile under planar kinetics of a rigid body shows the rigid body on the plane when forces are applied and produces work and energy. There are similarities and differences between both of it. Kinetics of a particle Planar kinetics of a…

The Father of Modern Science: Galileo Galilei Galileo Galilei is an important historical figure who is known as the Father of Modern Science. He was a polymath meaning he excelled in many sciences. He was a physicist, an astronomer, a mathematician, and an excellent inventor. Galileo greatly affected history and if he had not made his discoveries it is possible that we could be living in a very different world today. In the beginning… Galileo Galilei was born on February 15, 1564, in Pisa, Italy…

Erwin Schrödinger was a physicist pioneer who gave a series of lectures in 1944. They were published under the title What is Life? (Harold, 2001). Though philosophical in nature, many have wondered if life can be reduced to biology or even further down to chemistry. This sent many scientists looking for the answer and spawned the guiding question, could human life be artificially created at the cellular level? This would consist of arranging the correct amounts of various elements into the…

The Quantum-Mechanical Model of the Atom Introduction: The theory of quantum mechanics explains the behavior of the particles, such as photons (particles of light) and electrons, in the atomic and subatomic realms. Since the electrons of an atom determine many of its chemical and physical properties, quantum mechanics is foundational to understanding chemistry. Quantum-Mechanical Model- a model that explains the strange behavior of electrons Electromagnetic Radiation- a type of energy…

In 1905 German physicist Albert Einstein published the first paper of a new age of Physics. His theory of special relativity, followed by general relativity and the Einstein Field Equations in 1915, and the Copenhagen interpretation of quantum mechanics in 1925 combined to form a more significant shift in natural philosophy…

Imagine, if you were not yourself, yet at the same time you were. Imagine that you had led a completely different life. Maybe you were a soldier, an engineer, a banker, or maybe you did nothing with your life. What if you were born a with a different name, different gender, a different race; what if you were not born at all. Imagine a world where the American Revolution never happened, The Allies fell to the Axis, or the Cold War ended in nuclear annihilation. However, none of these scenarios…

Introduction The main objective of this lab is to observe the behavior of a metal block while experiencing uniaxial translation and oscillation in respects to time to calculate the acceleration, spring constant, and damping factor. The experiment was split into two different labs. Part one, the drop test, to take the block to a fixed height and drop it. This would then allow us to calculate the friction force, along with the acceleration of the metal block. Part two, the bounce test, is…

The theory of backwards causation, or retro-causation, has been given much attention in the past twenty years. It has made waves in metaphysics, quantum physics, and even religion. In the case of religion, it pulls into question God’s divine foreknowledge, in other words omniscience. This is an attempt to reconcile the foreknowledge of God with the possibility of backwards causation. Thus if is it impossible to do so then the options present themselves as: God has no divine foreknowledge,…

The visible pulse (gating pulse) enters the microscope, and together with the ultrafast electron pulses illuminate the nanostructure specimen (gold nanoparticle). The visible laser pulse kept at low power (~1.8 mJ/cm2) to avoid saturation. At the spatiotemporal overlapping, the coupling between the visible and electron pulses takes place. The signature of this coupling can be revealed by measuring the electron energy spectrum using the electron energy spectrometer attached to the microscope. The…
