One of the biggest concerns in the United States of America today is privacy. For its citizens, this concern is due mostly in part to new developments in technology and big data collection. Yes, this technology and data collection is beneficial for American citizens and is a step in the right direction for humankind, but to what extent? The CQ Researcher article titled, “Big Data and Privacy” by Tom Price answers just that question. More specifically, a monumental factor for technological advancement

predictable, the paths of particles are unknowable, because the act of observing a particle will alter it or its path in some way. Thus, rather than dealing with absolute positions, directions and speeds quantum physics uses statistics to predict the position of particles. This means that for a given particle we only have a probability of where it will be. Now the behaviour of large numbers of particles is much easier because lots of these elusive particles acting together and

Far away, on the border of both France and Switzerland, lies the massive CERN Accelerator Complex. This series of particle accelerators increases the momentum of packets of nuclei to almost light speed, then collides them. It collects the debris of the resulting destruction in hopes of finding the basic building blocks of matter. This is a basic overview of what happens at CERN, but when examined more closely, this process becomes far more difficult and complicated. How does this “Atom Smasher” work

Sub-atomic particles, known as quarks, electrons, photons, and neutrinos were strewn across expanding space. Equal amounts of matter and antimatter particles began to collide and annihilate each other. Gravity, strong and weak nuclear forces, and electromagnetic forces soon came into play. As the universe started to cool, fundamental particles called quarks began to smash together forming protons and neutrons. They, in turn, merged to create the nuclei of simple elements, beginning with hydrogen

are the elementary particles observed. the strings have tension of 1/(2 p a’) strings are approximately the planck length (smallest possible size of black hole) 10^(-33) cm A quantum Theory of Gravity is needed In physics there are two main central theories. The first is

remember asking my team members why we did not need to calculate as much for the return trip thinking about the moon Europa’s gravity? “Of course, it is a factor but the gravity of earth compared to Europa is very different (Europa’s gravity is very like our moon, which is 5/6 less than earth’s gravity).” A team member responded. The escape velocity (4) (the velocity required for an object to leave the gravitational field) to leave earth was one that my space craft needed to beat in order for my

oscillating neutrinos, and have come to believe that they’re getting very close to understanding these bizarre particles. FERMILAB LAUNCHES NEUTRINOS FARTHER This scientific advancement is the result of Fermilab’s ongoing NOvA experiment, which hopes to uncover the secrets of those elusive particles called neutrinos. The study released its final results earlier this week. The experiment’s gigantic particle detector is capable of detecting neutrinos fired from an impressive 500 miles’ distance, but the scientists

Nuclear physics in the society development Nuclear physics is the field of physics that studies atomic nuclei and their constituents and interactions. The most commonly known application of nuclear physics is nuclear power generation, but the research has led to applications in many fields, including nuclear medicine and magnetic resonance imaging, nuclear weapons, ion implantation in materials engineering, and radiocarbon dating in geology and archaeology. Nuclear physics has a lot of importance

radioactive materials is radiation therapy. Radiation therapy utilizes X and gamma rays to target and kill the cancer cells. “Radiation therapy kills cancer cells by damaging their DNA. Radiation can either damage the DNA directly or create charged particles in cells that in turn damage the DNA.” (“Radiation Therapy for Cancer”) Radiation therapy affects only the selected area of treatment, whereas other treatments such as chemo therapy affects the entire body. Radiation therapy can be administered two

external-beam photon therapy (ref 40). Proton beam therapy (PBT) is a novel form of external beam radiotherapy technique that utilises positively charged particles in cancer management (ref required). However, the idea of using charged particles for cancer treatment is not new. Robert R. Wilson was a famous American phycist who proposed that, heavy particles could be used to treat cancer (Wilson, 1946). Thereafter, in 1954, the first cancer patient was treated using PBT at the Berkeley Radiation Laboratory
