Using gravity assist for deceleration?
Gravity assist has been used for decades to accelerate and decelerate spacecraft bound for other planets, but would this process be feasible for decelerating an interstellar spacecraft at the end of its journey, given the higher speeds involved?
Would the best method be an encounter with the destination star or to aim for Jupiter- or larger-sized planets first? Would this process necessarily take years to produce any substantial benefits?
2 AnswersPhysics8 years agoreal time xml counter applet?
Hi, I'm looking for an XML counter like the National Debt Clock, where I can set the variables myself.
For example, Company X made $30 million in profits last year, that breaks down into so much per day, per hour, per minute, per second.
I'd like to be able to show all four counters as they keep a running total.
I'd like to be able to input a start date/time (say their fiscal year begins at one second past midnight on October 1...) and the initial profit per second, which the other counters would build off.
If possible, I'd like it to run in real time so visitors to the web page can see the numbers change.
Can this be done? What is something like this even called?
3 AnswersProgramming & Design10 years agoA 501 (c)(3) non-profit org compliance question?
Under IRS 501 (c)(3), an organization is tax-exempt as long as it meets the requirements set forth in IRC 509(a)(2).
The "One-Third Limit On Gross Investment Income and Unrelated Business Income" test set out in IRC 509(a)(2) states that "An organization will meet this test only if it normally receives not more than one-third of its total support in each taxable year from gross investment income"
If a non-profit received $29 million dollars in donations last year, and earned another $26 million on investments from an endowment fund, has it violated the terms of the "One Third Limit"?

3 AnswersLaw & Ethics1 decade agoShould non-kosher consumers be forced to subsidize kosher certification?
Currently, the vast majority of food products sold in American grocery stores have been examined by kosher certifiers. Those that pass can print an obscure symbol, such as a U in a circle or simply the letter "K" on the label. Those who do not recognize these symbols, or read hebrew, are unaware that the product is kosher.
Since less than 2% of the US poplation keeps kosher, the costs of this process are passed on to unwitting non-kosher consumers. Kosher activists love to trot out a tired 1975 article from the NY Times in which an unnamed source claims that the cost per unit for certification is "6.5 millionths of a cent", but this is ludicrous. At that rate the rabbis would only collect one dollar for every 6.5 BILLION units sold.
So, in all fairness, should non-kosher consumers continue to be forced to subsidize a system that in no way improves the quality of our food supply?
1 AnswerOther - Business & Finance1 decade agoDid Ron Paul really agree to appear in a spanish language debate?
On November 9, the Miami Herald reported that Congressman Paul had agreed to join the rest of the Republican traitor candidates in a mexican debate on Dec. 9.
Isn't a command of the English language a prerequisite to obtaining American citizenship? To whom is Mr. Paul pandering with this disgusting stunt?
4 AnswersPolitics1 decade agoHow hot were the Apollo rock samples?
Since lunar day time temperatures can reach 250 degrees F, and since the surface of the moon is almost a near vacuum, wouldn't any rocks an astronaut picked up be extremely hot?
(Granted, the lunar landings were always scheduled before local "high noon" to ensure good shadows, the rocks must still have been thoroughly heated.)
3 AnswersAstronomy & Space1 decade agoShould George Bush visit Tehran?
In the 1950s and 60s, Richard Nixon was one of the staunchest opponents of Communism and fought the Soviets and Red Chinese at every opportunity.
In 1972, however, Nixon flew to Peking and reopened China to the West. Two months later Nixon was in Moscow signing the Anti-Ballistic Missile treaty with Brezhnev.
Despite the stupidity that ended his career, there can be little doubt that Nixon's two acts of statemanship have changed the world.
Should Bush follow Nixon's example and confront the Iranians, the Syrians, and even the North Koreans on their own doorsteps? He has little to lose and everything to gain.
(Islamo-bashers, please cool your jets and let the intelligent people answer first.)
