Doppler Effect is the “apparent change in the wavelength of radiation due to the relative motion between the source and the observer along the line of sight.” (Slater) b. The Doppler Effect is important to astronomers because it gathers “basic information about the motions of planets, stars, and galaxies.” (Slater) 10. If you see a blue star, what does its color tell you about how the star is moving through space? Explain your answer. (Pages 49 – 50) a. By seeing a blue star, you can…

The purpose of this spectroscopy experiment was to determine if the spectra matched the electronic transitions that occur in the hydrogen atom among several other atoms. We used the Bohr model of atomic structure to determine the orbit numbers that correspond with the spectrum emitted by the hydrogen atom. The Bohr model states that electrons will never be found in between states, but rather completely in one state or the other. We used this model to determine the initial n value at which the…

Knowledge: The limits of science and the Search for Meaning Marcelo Gleiser is a brilliant world-renowned physicist and astronomer who was born in Brazil in the year of 1959.He has received many awards for his position as a professor at Dartmouth College. He has taught physics, astronomy, and natural philosophy. In 2014 his great knowledge and thirst for the scientific answers to nature’s wonders led him to write a book called The Island of Knowledge: The Limits of Science and the search for…

Swap the tights for a $3000 suit and the Batmobile for an Aston Martin, and voila, you’ve got yourself a hero! However, James Bond, being the egotistical character that he is, isn’t quite as merciful and emotionally driven as our everyday heroes, which makes us wonder, is Bond a hero… or not? 2006 film Casino Royale directed by Martin Campbell, is the first of the James Bond movies to star Daniel Craig as 007. Armed with a Walther PPK and a license to kill, Bond sets out on a daring mission to…

Using empirical equations like this is a common trick in science; find a mathematical function that fits what you’ve observed, then use that as a clue to what’s happening behind your observations. Planck had taken this second step, and was looking for a theoretical derivation of what became Planck’s Law. This gave…

In this study, the effect of benzenethiol ligand on CdSe/ZnS core/shell quantum dots was investigated. Conventional long-chain oleic acid (OA) and trioctylphosphine (TOP) capping ligands were partially replaced by short benzenethiol ligands, and the improvement in the luminescence performance was observed in quantum dot light emitting diodes (QD-LED). Approximately 1.8 fold improvement was achieved for both the maximum luminance and maximum current efficiency for the QD-LEDs fabricated with…

The purpose of this spectroscopy, atomic spectra, and light lab was to further your understanding of how different gases are given specific wavelengths based on the variety of color that their light gives off. (Grossie, 285). Every ion gives off a different light configuration based on the amount of energy they hold. (Grossie, 285). A spectroscope is used to break down the light given off by the gas into different colored lines in different areas on the scope. The measure of these lines is what…

Supplemental information for “Colloidal Type-II CdS/ZnSe NCs : Synthesis, Electronic Structures, and Spectroscopic Properties” S.A. Ivanov, A. Piryatinski, J. Nanda, S. Tretiak, D. Werder, V. I. Klimov Theoretical model. To describe quantum states in a spherically symmetric Type-II core/shell nanocrystals (NC) characterized by the core radius R and the shell width H, we use effective mass approximation. We assume the existence of single energy bands for both electrons and holes. This assumption…

Electron microscope (Manning, n.d.) is the instrument used to magnify different scientific artifacts with the used of electron beams to create the illustration of the sample, and has the capacity to magnify two million times of the original specimen. The development of the electron microscope was first known in the year 1931 because Ernst Ruska and Maximoll Knoll magnified electron image successfully, but the equipment was actually constructed in 1933 (Innes, n.d.). The concept of the electron…

of co-presence in the light of physics, mathematics, and cosmology, he appeals to the examples of non-Hausdorff manifolds and Cantor’s threefold concept of the finite, the transfinite, and the infinite in mathematics and to the non-locality of quantum mechanics. Thereby, he renders co-presence as an infinite fractal-like character. To be more specific, gleaning from Pannenberg the idea of the dialectical mutual indwelling of the finite and the infinite, based on Hegel’s concept of…
