First day of summer 2008

June 20th was the first day of summer for 2008. The first day of summer is also the summer solstice.

Solstices occur twice a year, when the tilt of the Earth's axis is most oriented toward or away from the Sun, causing the Sun to reach its northernmost and southernmost extremes. The name is derived from the Latin sol (sun) and sistere (to stand still), because at the solstices, the Sun stands still in declination; that is, its apparent movement north or south comes to a standstill.

The term solstice can also be used in a wider sense, as the date (day) that such a passage happens. The solstices, together with the equinoxes, are connected with the seasons. In some languages they are considered to start or separate the seasons; in others they are considered to be centre points (in English, in the Northern hemisphere, for example, the period around the June solstice is known as midsummer, and Midsummer's Day is 24 June, about three days after the solstice itself). Similarly 25 December is the start of the Christmas celebration, which was a Pagan festival in pre-Christian times, and is the day the sun begins to return back to the northern hemisphere.

It depends where you live, since the first day of summer is timed with the summer solstice. For most of the United States, summer begins on June 20. In Europe it's June 21. In Australia it's six months later, on December 21.

On the other hand, if you are looking for an "official" first day of summer, there is no such thing. The United States, for instance, has never declared when the seasons start. The International Astronomical Union hasn't either. In many areas of Europe, May 1st is considered the first day of summer (as the meterologists in the United States do) with the Summer Solstice being the "Midsummer" (as in Shakespeare's play).

Video about pregnant girls at Gloucester High School

This video focuses on why teenage girls are getting pregnant. Christen Callahan talks about her conversation with girls of Gloucester High School about pregnancy.

17 Teenage Girls Made Pregnancy Pact

From: Time.com

As summer vacation begins, 17 girls at Gloucester High School are expecting babies—more than four times the number of pregnancies the 1,200-student school had last year. Some adults dismissed the statistic as a blip. Others blamed hit movies like Juno and Knocked Up for glamorizing young unwed mothers. But principal Joseph Sullivan knows at least part of the reason there's been such a spike in teen pregnancies in this Massachusetts fishing town. School officials started looking into the matter as early as October after an unusual number of girls began filing into the school clinic to find out if they were pregnant. By May, several students had returned multiple times to get pregnancy tests, and on hearing the results, "some girls seemed more upset when they weren't pregnant than when they were," Sullivan says. All it took was a few simple questions before nearly half the expecting students, none older than 16, confessed to making a pact to get pregnant and raise their babies together. Then the story got worse. "We found out one of the fathers is a 24-year-old homeless guy," the principal says, shaking his head.

What is the speed of light?

the speed of light = 299 792 458 m / s

The speed of light in the vacuum of free space is an important physical constant usually denoted by the letter c.[1] It is the speed of all electromagnetic radiation, including visible light, in free space. It is the speed of anything having zero rest mass.[2] The SI metre is defined such that the speed of light in a vacuum is exactly 299,792,458 metres per second (1,079,252,849 km/h).[3] The speed of light can be assigned a definite numerical value because the fundamental SI unit of length, the metre, has been defined since October 21, 1983, as the distance light travels in a vacuum in 1/299,792,458 of a second; in other words, any increase in the measurement precision of the speed of light would refine the definition of the metre, but not alter the numerical value of c. The approximate value of 3×108 m/s is commonly used in rough estimates (the error is 0.07%). In imperial units, the speed of light is about 670,616,629.4 miles per hour or 983,571,056.4 feet per second (roughly one foot per nanosecond), which is about 186,282.397 miles per second.

The speed of light when it passes through a transparent or translucent material medium, like glass or air, is less than its speed in a vacuum. The ratio of the speed of light in the vacuum to the observed phase velocity is called the refractive index of the medium. See dispersion (optics). In general relativity c remains an important constant of spacetime, however the concepts of 'distance', 'time', and therefore 'speed' are not always unambiguously defined due to the curvature of spacetime caused by gravitation. When measured locally, light in a vacuum always passes an observer at c.

When we deal with the immense distances of space, though, even light seems slow. When astronauts were on the Moon it took over a second for the radio waves (which travel at the speed of light) carrying their voices to reach us. Light coming from the sun takes eight and one half minutes to hit Earth. (This means that if the sun were suddenly to go dark, it would take over eight minute for us to notice) Light from the nearest stars, other than the sun, takes four and a half years to get here. From the farthest stars in distant galaxies it can take billions of years for the light to arrive..

Light years

Astronomical distances are sometimes measured in light years (the distance that light would travel in one Earth year, roughly 9.46×1012 kilometres or about 5.88×1012 miles). Because light travels at a large but finite speed, it takes time for light to cover large distances. Thus, the light we observe from distant objects in the universe was emitted from them long ago: in effect, we see their distant past. Even in terms of our own star we see into the past as well. Light from the sun takes around eight and one-third minutes to reach the earth.

Obama opts out of public funding

Democratic presidential candidate Barack Obama said Thursday he'll bypass the federal public financing system in the general election, abandoning an earlier commitment to take the money if his Republican rival did as well. obama

Obama, who set records raising money in the primary election, will forgo more than $84 million that would have been available to him in the general election. He would be the first candidate to do so since Congress passed 1970s post-Watergate campaign finance laws. Sen. John McCain, the Republican nominee in waiting, has taken steps to accept the public funds in the general election.

Obama officials said they decided to take that route because McCain is already spending privately raised funds toward the general election campaign. Obama has vastly outraised McCain, however, and would likely retain that advantage if McCain accepts the public money.

Public Funding of Presidential Elections

Public funding of Presidential elections means that qualified Presidential candidates receive federal government funds to pay for the valid expenses of their political campaigns in both the primary and general elections. National political parties also receive federal money for their national nominating conventions.

When and How Did it Begin?

The Federal Election Commission administered the first public funding program in 1976. Eligible Presidential candidates used federal funds in their primary and general election campaigns, and the major parties used public funds to pay for their nominating conventions. Legislation for public financing of Presidential candidates was first proposed, however, in 1907. In his State of the Union message that year, President Theodore Roosevelt recommended public financing of federal elections and a ban on private contributions.

In 1966, Congress enacted the first public funding legislation, but suspended it a year later. That law would have made U.S. Treasury funds available to eligible nominees in the Presidential general election through payments to their political parties. Funds would have come from a Presidential Election Campaign Fund in the U.S. Treasury consisting of dollars voluntarily checked off by taxpayers on their federal income tax returns. A subsidy formula would have determined the amount of public funds available to eligible candidates.

In 1971, Congress adopted similar provisions, which formed the basis of the public funding system in effect today. Under the 1971 Revenue Act,1 the nominee, rather than the party, receives the public funds accumulated through the dollar checkoff. The Revenue Act also placed limits on campaign spending by Presidential nominees who receive public money and a ban on all private contributions to them.prez1

In a parallel development, Congress passed the 1971 Federal Election Campaign Act,2 which required full, detailed reporting of campaign contributions and expenditures by all federal candidates, including Presidential candidates. The 1974 Amendments3 to the Federal Election Campaign Act completed the system we now have for public financing of Presidential elections. Those Amendments extended the public funding provisions of the Revenue Act to Presidential primary elections4 and the Presidential nominating conventions of national parties. Court challenges to the expenditure limits followed soon after Congress passed the 1974 Amendments. However, the Supreme Court, in two separate suits, first implied and later affirmed that expenditure limits for publicly funded Presidential candidates are constitutional. (See Buckley v. Valeo (1976) and Republican National Committee v. FEC (1980).) In 1976, Congress made minor changes to the public funding provisions and in 1979 and 1984 increased the public funding entitlement and spending limit for national nominating conventions.5

How Does Public Funding Work?

To qualify for public funding, Presidential candidates and party convention committees must first meet various eligibility requirements, such as agreeing to limit campaign spending to a specified amount. Once the Federal Election Commission determines that eligibility requirements have been met, it certifies the amount of public funds to which the candidate or convention committee is entitled. The U.S. Treasury then makes the actual payments from the Presidential Election Campaign Fund. This fund consists of dollars voluntarily checked off by taxpayers on their federal income tax returns. (In 1993, the taxpayer checkoff was increased from $1 to $3. Public Law 103-66) The checkoff neither increases the amount of taxes owed nor decreases any refund due for the tax year in which the checkoff is made.

Primary Matching Funds

prez2 Partial public funding is available to Presidential primary candidates in the form of matching payments. The federal government will match up to $250 of an individual's total contributions to an eligible candidate.

Only candidates seeking nomination by a political party to the office of President are eligible to receive primary matching funds. In addition, a candidate must establish eligibility by showing broad-based public support. He or she must raise in excess of $5,000 in each of at least 20 states (i.e., over $100,000). Although an individual may contribute up to $2,300 to a primary candidate, only a maximum of $250 per individual applies toward the $5,000 threshold in each state.

Candidates also must agree to:

  • Limit campaign spending for all primary elections to $10 million plus a cost-of-living adjustment (COLA).6 This is called the national spending limit.
  • Limit campaign spending in each state to $200,000 plus COLA, or to a specified amount based on the number of voting age individuals in the state (plus COLA), whichever is greater.
  • Limit spending from personal funds to $50,000.

The campaign finance law exempts the payment of some expenses from the spending limits. Certain fundraising expenses (up to 20 percent of the expenditure limit) and legal and accounting expenses incurred solely to ensure the campaign's compliance with the law do not count against the expenditure limits.

Once they have established eligibility for matching payments, Presidential candidates may receive public funds to match contributions from individual contributors, up to $250 per individual. The contributions must be in the form of a check or money order. (Purchases of tickets to fundraisers and contributions collected through joint fundraising are matchable contributions, but loans, cash contributions, goods or services, contributions from political committees and contributions which are illegal under the campaign finance law are not matchable.)

Even if they no longer campaign actively in primary elections, candidates may continue to request public funds to pay off campaign debts until late February or early March of the year following an election. (However, to qualify for matching funds, contributions must be deposited in the campaign account by December 31 of the election year.) Eligible candidates may receive public funds equaling up to half of the national spending limit for the primary campaign. Because candidates receive many nonmatchable contributions, such as those from political committees, they generally raise more money than they receive in matching funds.

General Election Funding

The Presidential nominee of each major party may become eligible for a public grant of $20 million (plus a cost-of-living adjustment) for campaigning in the general election.7 To be eligible to receive the public funds, the candidate must limit spending to the amount of the grant and may not accept private contributions for the campaign. Private contributions may, however, be accepted for a special account maintained exclusively to pay for legal and accounting expenses associated with complying with the campaign finance law. These legal and accounting expenses are not subject to the expenditure limit.

In addition, candidates may spend up to $50,000 from their own personal funds. Such spending does not count against the expenditure limit.

Minor party candidates and new party candidates may become eligible for partial public funding of their general election campaigns. (A minor party candidate is the nominee of a party whose candidate received between 5 and 25 percent of the total popular vote in the preceding Presidential election. A new party candidate is the nominee of a party that is neither a major party nor a minor party.) The amount of public funding to which a minor party candidate is entitled is based on the ratio of the party's popular vote in the preceding Presidential election to the average popular vote of the two major party candidates in that election. A new party candidate receives partial public funding after the election if he/she receives 5 percent or more of the vote. The entitlement is based on the ratio of the new party candidate's popular vote in the current election to the average popular vote of the two major party candidates in the election.

Although minor and new party candidates may supplement public funds with private contributions and may exempt some fundraising costs from their expenditure limit, they are otherwise subject to the same spending limit and other requirements that apply to major party candidates.

Convention Funding

Each major political party is entitled to $4 million (plus cost-of-living adjustments)8 to finance its national Presidential nominating convention. A qualified minor party may become eligible for partial convention funding based on its Presidential candidate's share of the popular vote in the preceding Presidential election.

A party convention committee may not spend more than the amount to which the major party is entitled. Contributions may be accepted, however, for a special account maintained exclusively to pay for legal and accounting expenses associated with complying with the campaign finance law. Contributions to this account count against the donor's annual limit for the Party. Certain supplemental services may also be provided by the host state and city governments and by local groups such as businesses and labor unions. The host city may, for example, provide additional public transportation to and from the convention site. Or a business may sell or rent chairs, podiums, tables or other equipment to the convention committee at discount rates.

What is the FEC's Role?

The Federal Election Commission ensures that candidates and convention committees requesting public funds have satisfied the eligibility requirements. The FEC then certifies payments of federal funds, which are actually made by the U.S. Treasury. Before certifying matching payments to primary candidates, the FEC first reviews submitted contributions to make sure they meet the requirements for matchability. Additionally, the FEC audits all public funding recipients to ensure that the funds were spent in compliance with the law. Under certain circumstances, the FEC may require the repayment of public funds.

Eligibility for Public Funds

To be eligible for public funds, a Presidential candidate or a party convention committee must first submit a letter of agreement and a written certification in which the candidate or committee agrees to:

  • Spend public funds only for campaign-related expenses or, in the case of a party convention, for convention-related expenses;
  • Limit spending to amounts specified by the campaign finance law;
  • Keep records and, if requested, supply evidence of qualified expenses;
  • Cooperate with an audit of campaign or convention expenses;
  • Repay public funds, if necessary; and
  • Pay any civil penalties imposed by the FEC.

Primary candidates must additionally certify that they have met the "threshold requirement" for eligibility by raising in excess of $5,000 in each of 20 states (see "Primary Matching Funds," above). A candidate may satisfy eligibility requirements and submit private contributions for matching payments any time after January 1 of the year before a Presidential general election. Actual payments are not made, however, until after January 1 of the Presidential election year.

Repayments of Public Funds

The Commission requires candidates and convention committees to repay public funds to the U.S. Treasury when the FEC audit determines that:

  • The amount of public funds received exceeds the amount to which the candidate or convention committee is entitled;
  • Spending limits are exceeded;
  • Public funds are used for purposes other than qualified campaign expenses;
  • Surplus funds remain after debts and obligations have been paid;
  • Interest is earned on invested public funds; or
  • The spending of public funds is not sufficiently documented.

Presidential candidates and convention committees may challenge any FEC repayment determination by following the procedures spelled out in FEC regulations.

How Can I Support My Candidate?

The following paragraphs have been written exclusively for individuals, to explain how they may support Presidential candidates. (Political committees and other organizations should call the Commission in Washington, D.C., toll free 800/424-9530 or 202/694-1100.)

Contributions to Primary Candidates

You may contribute up to $2,300 to a Presidential candidate in the primary election campaign, whether or not the candidate accepts matching funds. (The $2,300 limit applies to the entire primary process, rather than to a single primary held in a particular state.)

Contributions to Major Party Nominees in the General Election

A major party nominee who has accepted public funding for the general election may not accept any contributions to further his election. You may, however, help a publicly funded nominee by contributing to the candidate's compliance fund. A compliance fund is a special account maintained by publicly funded nominees solely for paying legal and accounting expenses incurred in complying with the campaign finance law. You may contribute up to $2,300 to the compliance fund of a major party nominee.

In the case of a major party nominee who is not publicly funded, you may contribute up to $2,300 to his/her general election campaign.

Contributions to Minor and New Party Nominees in the General Election

You may contribute up to $2,300 to the general election campaign of a minor or new party candidate, whether or not the candidate accepts public funds.

Independent Expenditures

In both the primary and general elections, you may make your own "independent expenditures" to support or oppose a Presidential candidate, whether or not the candidate receives public funds. An independent expenditure is an expenditure for a communication that expressly advocates the election or defeat of a clearly identified candidate. An independent expenditure is not considered a contribution and therefore does not count against contribution limits as long as the expenditure is completely independent of the candidate's campaign. This means you may not make the expenditure at the request or suggestion of the candidate or his/her aides or with their consent. Nor may you consult or cooperate in any way with the candidate or campaign aides. Additionally, you may not use any material prepared by the candidate or campaign in the communication.

Within these restrictions, you may, for example, place an ad on a billboard or in a newspaper urging the public to vote for your candidate. However, you must place a notice on the communication stating that you have paid for it and that it has not been authorized by any candidate (e.g., "Paid for by John Doe and not authorized by any candidate").

You must file a report with the Commission when the total amount of your independent expenditures aggregates over $250 during the calendar year. For more information, consult the Commission's Independent Expenditures brochure.

Volunteer Services

You may volunteer your services to a Presidential candidate's primary and general election campaigns (whether or not the candidate receives public funding) and to the candidate's political party. However, you must volunteer the services on your own time, not on your employer's time.prez3

You may also pay for certain expenses as a volunteer. As long as you do not exceed certain limits, the money does not count as a contribution to the candidate. However, if you exceed the limits placed on these expenses, the amount over the limit counts as a contribution. Therefore, when spending money on volunteer activity for major party nominees receiving public funds, you must not exceed the limits.

You may travel on behalf of the candidate, spending up to $1,000 both in the primary and general election campaigns. In addition, you may spend up to $2,000 annually for travel on behalf of the candidate's party. You may spend any amount in normal living expenses incurred while traveling or engaging in other volunteer activity.

You may hold a reception in your home or in a church or community room for the candidate or the candidate's party. You may spend up to $1,000, both in the primary and general elections, for food, beverage and invitations associated with the candidate's reception. For a reception held to benefit the candidate's party, you may spend up to $2,000 annually for the same items.

Contributions to Party Committees

You may contribute up to $28,500 a year to a national party committee and up to $5,000 a year to a state or local party committee. (A state party committee and the local party committees within that state usually share one $5,000 annual limit on contributions from a person.) Although major party committees are not permitted to contribute to their nominee in the general election if he or she accepts public funds, the national committee of a political party may support the nominee by making special, limited expenditures on his or her behalf, as indicated in the Chart on Expenditure Limits. The party's national committee may designate a state or local party committee to make these expenditures. In addition, state and local party committees may conduct voter drives on behalf of the Presidential nominee and distribute pins, bumper stickers and other campaign materials benefiting the nominee.
