The main objectives in this lab included: determining the relationship between the energy, frequency, and the wavelength of waves, identifying line and band spectra, determining the relationship between the colors of the visible light spectrum and their corresponding wavelengths and frequencies, determining an unknown element and the measurement of its emission spectrum, and lastly understanding the difference between frequency, wavelength, velocity, and interference.
To properly understand the frequency, wavelength, and interference a slinky was used to show the different variations. When the slinky was moved very quickly in short strokes, this resulted in a high frequency with shorter wavelengths. When the slinky was moved with huge, slow strokes, there was low frequency and long wavelength. Constructive interference was illustrated when both people on either side of the slinky sent their waves at the same time, and on the same side. They constructed together and the wave continued. Deconstructive interference …show more content…
Also by using a spectroscope to observe the spectra of Helium, Argon, Mercury, and Neon emissions. This was done to compare the gaseous spectra to a solid spectra. The spectroscope directed at a flourescent light bulb showed a full line spectra, meaning every light was visible in the light bulb. Unfortunately the same elements weren’t burnt as those that were observed using the spectroscope so it wasn’t possible to compare the line and band spectrums together. Although, line spectrums were more prevalent in the gaseous stage and band spectrums were more common in a solid form. This is because the line spectrum is more easily observable when in a compact form such as a solid, compared to a gas where the atoms are bouncing around

Procedure: * For Hydrogen I placed a piece of Zn metal into a test tube with diluted HCl. * To produce oxygen I added Hydrogen peroxide to manganese. * Next, I added baking soda to vinegar. This caused a quick and energetic reaction! The gas from the reaction I pumped into some Limewater. * Then I mixed Alka Seltzer and water and pumped the gas caused by that reaction into some limewater.

Feasibility of Using Biosensors for Heavy Metal Detection in Complex Matrices Such as Bio-Slurries.

...to be watched very closely to avoid spreading of contaminants on area and poisoning of humans and animals. Because heavy metals are very stable and toxic in many chemical compositions, their amount should be estimated very thoroughly. A new approach that involved biosensors was tested in this study. Because the slurries are complex non-unified matrices which composed of two phases – solid and liquid, the cell behavior can varies a lot from the one that explained in water and so the estimation of ion concentration can be not reliable. It was shown that the cell actually behave different in the slurries. Normally the dissolved compounds suppress the biosensor activity and, in the same time, the ions in the particles can released during the tests and interfere with the signal. So the concentration and the pretreatment of the samples should be chosen for every particular biosensor. Additionally, there was an attempt to measure the heavy metal amount and to compare it with the results that were obtained on AAS. The data declares that the bioavailability may differ in the matrices and so the...

The Turing Triage Test

...1 The Turing Triage Test Dr. Robert Sparrow Centre for Human Bioethics Faculty of Arts Monash University Victoria 3800 Australia. This paper appeared in print in: Ethics and Information Technology 6(4): 203-213. 2004. Please cite that version. 2 The Turing Triage Test Abstract If, as a number of writers have predicted, the computers of the future will possess intelligence and capacities that exceed our own then it seems as though they will be worthy of a moral respect at least equal to, and perhaps greater than, human beings. In this paper I propose a test to determine when we have reached that point. Inspired by Alan Turing’s (1950) original ‘Turing test’, which argued that we would be justified in conceding that machines could think if they could fill the role of a person in a conversation, I propose a test for when computers have achieved moral standing by asking when a computer might take the place of a human being in a moral dilemma, such as a ‘triage’ situation in which a choice must be made as to which of two human lives to save. We will know that machines have achieved moral standing comparable to a human when the replacement of one of these people with an artificial intelligence leaves the character of the dilemma intact. That is, when we might sometimes judge that it is reasonable to preserve the continuing existence of a machine over the life of a human being. This is the ‘Turing Triage Test’. I argue that if personhood is understood as a matter of possessing...

...this situation sounds familiar, you may find it reassuring to know that many professionals undergo these same strange compulsions before they begin writing. Jean Kerr, author of Please Don’t Eat the Daisies, admits that she often finds herself in the kitchen reading soup-can labels—or anything—in order to prolong the moments before taking pen in hand. John C. Calhoun, vice president under Andrew Jackson, insisted he had to plow his fields before he could write, and Joseph Conrad, author of Lord Jim and other novels, is said to have cried on occasion from the sheer dread of sitting down to compose his stories. To spare you as much hand-wringing as possible, this chapter presents some practical suggestions on how to begin writing your short essay. Although all writers must find the methods that work best for them, you may find some of the following ideas helpful. But no matter how you actually begin putting words on paper, it is absolutely essential to maintain two basic ideas concerning your writing task. Before you write a single sentence, you should always remind yourself that 1. You have some valuable ideas to tell your reader, and 2. More than anything, you want to communicate those ideas to your reader. These reminders may seem obvious to you, but without a solid commitment to your own opinions as well as to your reader, your prose will be lifeless and boring. If you don’t care about your subject, you can’t very well expect anyone else to. Have confidence that your ideas are...

"Combines how-to with be-smart for an audience of job seekers, interviewers, Wired-style cognitive science hobbyists, and the onlooking curious. . . . How Would You Move Mount Fuji? gallops down entertaining sidepaths about the history of intelligence testing, the origins of Silicon Valley, and the brain-jockey heroics of Microsoft culture." — Michael Erard, Austin Chronicle "A charming Trojan Horse of a book While this slim book is ostensibly a guide to cracking the cult of the puzzle in Microsoft's hiring practices, Poundstone manages to sneak in a wealth of material on the crucial issue of how to hire in today's knowledge-based economy. How Would You Move Mount Fuji? delivers on the promise of revealing the tricks to Microsoft's notorious hiring challenges. But, more important, Poundstone, an accomplished science journalist, shows how puzzles can — and cannot — identify the potential stars of a competitive company....
