Mars Coming To Large View – Is This Hoax Amnesia Or Ignorance

It is unbelievable how many people believe all the nonsense that is circulating the Internet these days. Last year, 30 October 2005, we had the occurrence of Mars being close enough to Earth so that you could be spot it with the naked eye. But many people complained the next day that they saw nothing. The reason was that they have been hoaxed to believe that Mars will be as big is the moon, while it was in fact a bright star in the sky. This year we again have an e-mail circulating the Net, propagating the same lies again and the best of all, the e-mail states that this will only happen again in the year 2287, but according to NASA, this happens every two years.

DNA Testing Services

DNA testing services are invaluable services for people, organizations, or other institutions that may require a positive or negative identification on a person by way of biology. Surveys estimate that at least 200,000 DNA tests are annually conducted by states that are after the settlement of child support and paternity concerns. Recent advances in the field of DNA analysis have opened a wider horizon in the understanding of paternal relations. Furthermore, DNA testing services are also able to determine twin zygosity, siblingship, cousin and grandparent relationship and one’s ancestral origin.

Voltage Transformers

In order to switch on electrical equipment we need the mains supply which either provides us with an output of 110 Volts or 220 Volts of Alternating Current (AC). The question here is what the compatible voltage for the equipment is. If you find that your supply is 110 Volts and the equipment requires 220 Volts AC, you need a step-up voltage transformer to run that equipment. If it is the other way round, a setp-down voltage transformer would be required.

Modern UV-VIS Spectroscopy: A Decade of Fiber-Optic CCD Array Spectrophotometers

Ultraviolet-visible spectroscopy continues to be one of the core disciplines practiced in nearly every analytical laboratory. Since its inception by Cary and Beckman in the 1940s, UV-VIS spectroscopy has revolutionized the field of molecular spectroscopy. Over the decades, numerous improvements have been made with respect to optical designs, including dual-beam optics, variable slit resolution, noise suppression, and integrated electronics.

Science In Literature - Writers And Scientists Bridge The Gap

Fictional scientists are invariably portrayed as unscrupulous power seekers, out of touch with reality. At best they are caricatured as socially inept, white-coated misfits – think Jekyll, Frankenstein and Strangelove. All too often writers are forced to rely on these misguided stereotypes due to a lack of relevant knowledge but now an exciting project called SciTalk aims to bridge the perceived gap between writers and scientists by bringing them face to face.

The Value of a Science Fair Project

With the jam-packed schedules of today's families, why would either a student or a parent want to add one more major activity? Clearly, any school project assigned to a student should meet a stringent test for usefulness. Surprising to some, a science fair project is one of the best learning experiences a student can undertake. And, if it is taken seriously, it can be an excellent way to earn significant prizes, qualify for scholarships, and distinguish a college application.
