How many topics in physics are contained in a simple rainbow produced on the wall (and toilet) by sun shining through a plastic privacy screen?
Well...the light from the sun is composed of many different wavelengths...the distribution of which is dependent on the temperature of the star - which ours is centered on the the yellow. When the the light encounters an optically dense medium (glass or plastic in this case), the light is absorbed by the molecules and passed from molecule to molecule, the probability of which an absorption and emission occurs is described by Feynman's QED. The principle of least action (from D'Alembert and Lagrangian mechanics) finds the maximum probability amplitude, and hence the interaction that occurs, or the direction the light is refracted. The path of light through the medium is dependent on the wavelength and frequency of the light. One can back up to PAM Dirac's relativistic quantum mechanics, ingeniously melded Schrodinger's wave equation and/or Heisenberg's Matrix mechanics with Einstein's relativity, which determined that the only certainty in the universe is the speed of light. Everything else including Newton's fixed stars and time...TIME itself are mutable to make the speed of light constant in every situation. Dirac faced with the actual energy of a particle being the square root of the rest mass and its motion, devised a Hamiltonian that required matricies, later interpreted by Pauli as spin states of particles. Schoedinger and Heisenberg following Bohr's amazing leap of quantized orbits to describe Plancks description of light as quanta....actually they were named by Einstein to describe the photoelectric effect....but Planck needed the quantized description of light to explain the ultraviolet disaster of Rayleigh. Planck was working for the electric company to maximize the light output of municipal utilities at the least cost.... TBC
What proceeds death? Heaven or nothingness? If heaven exists where can its boundaries be drawn? For some, there is a very thin line that distinguishes heaven and purgatory. In this case, the line is a bit thicker, and the other side of the physical world is a bit more vague in its interpretation.
Death is a product of time; time elicits death, for time causes aging, decay, causality of death-inducing events, etc.
The 1st, 2nd, and 3rd dimensions are characterized by space. In a simple sense, the 4th dimension can be considered simply "time," but to be more concise, it is more-so "space-time" since time is dependent upon the movement of spatial objects to give reference to time. The physical world is characterized as space. The world changes because it is a space of transience due to its interference by time; time elicits death; all physical entities born within the world are born to die. But death—not simply human death, more-so the recycling of energy—is superseded by the response of birth, and thus life returns to its origin. For every death there is a birth. Existing is not simply an endeavor of the mind, body, soul, etc., but one of perpetual consciousness manifested in all things. It is a constant. To exist is to have existed, to exist now, and to exist forever.

Today, Hampton University Proton Therapy Institute - HUPTI announced a partnership with Leo Cancer Care to develop an upright proton arc therapy treatment technique for cancer.
The technique will allow patients to stand or sit upright and, combined with an additional CT system, may better target tumors in patients.
Jefferson Lab is proud to contribute to these efforts by applying its nuclear physics and technology expertise to help pave the way for improvements in patient care.

The Middle School Data Science Workshop is a one-day event for seventh grade students to learn about artificial intelligence and how it works. Students will learn about AI, look at code, modify it, and run it to train an AI model. Graphs will be made showing the performance of their models and they will learn how to read them.
