An anonymous reader writes "One of the basic utilities supplied with any operating system is a desktop calculator. These are often simple utilities that are perfectly adequate for basic use. They typically include trigonometric functions, logarithms, factorials, parentheses and a memory function. However, the calculators featured in this article are significantly more sophisticated with the ability to process difficult mathematical functions, to plot graphs in 2D and 3D, and much more. Occasionally, the calculator tool provided with an operating system did not engender any confidence. The classic example being the calculator shipped with Windows 3.1 which could not even reliably subtract two numbers. Rest assured, the calculators listed below are of precision quality."

For the second time in as many years, a student has made a discovery while participating in the Pulsar Search Collaboratory (PSC), a joint program between the National Radio Astronomy Observatory and West Virginia University designed to get students and teachers involved in analyzing data from the Robert C. Byrd Green Bank Telescope (GBT). This time it was high school sophomore Shay Bloxton, who discovered a brand new pulsar. "For Bloxton, the pulsar discovery may be only her first in a scientific career. 'Participating in the PSC has definitely encouraged me to pursue my dream of being an astrophysicist,' she said, adding that she hopes to attend West Virginia University to study astrophysics. Late last year, another West Virginia student, from South Harrison High School, Lucas Bolyard, discovered a pulsar-like object called a rotating radio transient. His discovery also came through participation in the PSC."

vsync64 writes "Last night, Congressman Dennis Kucinich (D-OH) spent 4 hours reading into the Congressional Record 35 articles of impeachment against George W. Bush. Interestingly, those articles (63-page PDF via Coral CDN) include not just complaints about signing statements and the war in Iraq, but also charges that the President "Sp[ied] on American Citizens, Without a Court-Ordered Warrant, in Violation of the Law and the Fourth Amendment,' 'Direct[ed] Telecommunications Companies to Create an Illegal and Unconstitutional Database of the Private Telephone Numbers and Emails of American Citizens,' and 'Tamper[ed] with Free and Fair Elections.' These are issues near and dear to the hearts of many here, so it's worth discussing. What little mainstream media coverage there is tends to be brief (USA Today, CBS News, UPI, AP, Reuters)." The (Democratic) House leadership has said that the idea of impeachment is "off the table." The Judiciary Committee has not acted on articles of impeachment against Vice President Cheney introduced by Kucinich a year ago.

canadian_right informs us that scientists from Caltech have found hints of a time before the Big Bang while studying the cosmic microwave background. Not only does the study hint at something pre-existing our universe, the researchers also postulate that everything we see was created as a bubble pinched off from a previously existing universe. This conjecture turns out to shed light on the mystery of the arrow of time. Quoting the BBC's account: "Their model suggests that new universes could be created spontaneously from apparently empty space. From inside the parent universe, the event would be surprisingly unspectacular. Describing the team's work at a meeting of the American Astronomical Society (AAS) in St Louis, Missouri, co-author Professor Sean Carroll explained that 'a universe could form inside this room and we'd never know.'"

mrcgran writes "Eweek is reporting on Red Hat's assurances that can continue to deploy Linux without fear of legal retribution from Microsoft. This, despite the increasingly vocal threats emanating from Redmond. 'In a scathing response to Ballmer's remarks, Red Hat's IP team said the reality is that the community development approach of free and open-source code represents a healthy development paradigm, which, when viewed from the perspective of pending lawsuits related to intellectual property, is at least as safe as proprietary software. "We are also aware of no patent lawsuit against Linux. Ever. Anywhere," the team said in a blog posting.'"
