Yeah - let's continue to play in a torrential downpour! That's a true test of golf.

Thanks For Paying Taxes - Here’s A Receipt.
Taxpayers should get a receipt so they know what they're paying for, a think tank called Third Way argues in a new paper.
Here's a sample from the group. It includes federal income tax and FICA, which funds Medicare and Social Security. Details are here.

The Coriolis Effect
In physics, the Coriolis effect is an apparent deflection of moving objects when they are viewed from a rotating reference frame. In a reference frame with clockwise rotation, the deflection is to the left of the motion of the object; in one with anti-clockwise rotation, the deflection is to the right. The mathematical expression for the Coriolis force appeared in an 1835 paper by a French scientist Gaspard-Gustave Coriolis in connection with hydrodynamics, and also in the tidal equations of Pierre-Simon Laplace in 1778. Early in the 20th century, the term Coriolis force began to be used in connection with meteorology.
The Coriolis effect is caused by the Coriolis force. Newton's laws of motion govern the motion of an object in an inertial frame of reference. When Newton's laws are transformed to a rotating frame of reference, the Coriolis and centrifugal forces appear. Both forces are proportional to the mass of the object. The Coriolis force is proportional to the rotation rate and the centrifugal force is proportional to its square. The Coriolis force acts in a direction perpendicular to the rotation axis and to the velocity of the body in the rotating frame and is proportional to the object's speed in the rotating frame. The centrifugal force acts outwards in the radial direction and is proportional to the distance of the body from the axis of the rotating frame. These additional forces are termed either inertial forces, fictitious forces or pseudo forces.[1] These names are used in a technical sense, to mean simply that the forces vanish in an inertial frame of reference.
Perhaps the most commonly encountered rotating reference frame is the Earth. Because the Earth rotates only once per day, the Coriolis force is quite small, and its effects generally become noticeable only for motions occurring over large distances and long periods of time, such as large-scale movement of air in the atmosphere or water in the ocean. Such motions are constrained by the 2-dimensional surface of the earth, so only the horizontal component of the Coriolis force is generally important. This force causes moving objects on the surface of the Earth to appear to veer to the right in the northern hemisphere, and to the left in the southern. Rather than flowing directly from areas of high pressure to low pressure, as they would on a non-rotating planet, winds and currents tend to flow to the right of this direction north of the equator, and to the left of this direction south of the equator. This effect is responsible for the rotation of large cyclones (see Coriolis effects in meteorology).

Race Maps Of America
New York - The dots are so dense they almost cannot help but be separated - yet the Big Apple still has clear pockets of ethnicity.
These are the maps that show the racial breakdown of America’s biggest cities.
Using information from the latest U.S. census results, the maps show the extent to which America has blended together the races in the nation’s 40 largest cities.
With one dot equalling 25 people, digital cartographer Eric Fischer then colour-coded them based on race, with whites represented by pink, blacks by blue, Hispanic by orange, and Asians by green. Gray is other.
The resulting maps may not represent what many might expect Barack Obama’s integrated rainbow nation to look like, as many cities have clear racial dividing lines. (Click the name of each city to view its map.)
In New York, the boundaries are so intensely coloured that they can hardly avoid being integrated. While the different racial groups still have their own areas, it is one of the most diverse of the major urban cities.
Detroit, for example, is infamous for its divide between black and white. But the map shows such a clear separation along the Eight Mile beltway that it is startling - almost bordering on segregation.
The strict east-west divide in Washington DC is also well known - but chilling to see so starkly outlined on the map of the nation's capital.
And in Los Angeles, the Latino population dominates the poorer areas of the city.
But, reassuringly, the maps do show that not all American cities are so divided.
San Antonio: The Texan city blurs the lines better than most - though a divide can still be seen.
San Antonio in Texas paints a much better picture of integration, with whites and Hispanics blurring the boundaries and no real sign of a rich white enclave.
Another Texan city, Houston, also shows a richer diversity of races spreading out from the centre and Las Vegas boasts a good mix.
San Francisco also presents a better picture of racial integration together with a larger Asian contingent.
The maps have quickly become a source of fascination for bloggers, even though the data used is a decade out of date.
‘I’d love to see the income data presented this way, too,’ said one.
Good magazine's Andrew Price said: 'What do we, as a society, want to see in maps like this? I think it's safe to say that the clear separation of races in Detroit is a symptom (or cause) of serious social problems.
'At the same time,' he added, 'it seems unrealistic to expect perfect integration and it's unclear if we should want that anyway. It's great that our cities have vibrant ethnic neighbourhoods.'
The maps are based on information from the 2000 census, but Mr Fischer, 37, said in a blog on his Flickr site: ‘I intend to do a 2010 version as soon as the census finishes tabulating the data. I think the full release is planned for next June.’
He told the Washington Post: 'I always knew that cities had these racial divisions, but seeing them set out so graphically, that was the striking thing about them.'
